Here comes the sun?

Drawing upon REITs as a source of capital for solar projects, however, is not without its challenges. The first challenge is to determine how much of a solar project’s assets qualify as the type of property that must comprise the majority of a REIT's assets.

The REIT rules refer to this type of property as "real property" and then define it as land and improvements on the land, such as buildings and other inherently permanent structures. The REIT rules specifically exclude from real property "assets accessory to the operation of a business."

When the REIT rules were enacted in 1960, Congress listed individual homes, apartment houses, office buildings, factories and hotels as types of property that REITs were intended to own. Since then,The lumi curvingmachiney is an uplight that can be mounted in the paving, deck, flooring or concrete. the IRS has taken the position that this list is not exclusive and that other types of property can be treated as "real property" based upon how permanently the property is attached to land.

Questions that the IRS asks when determining whether property is "inherently permanent" include the following: Is the property intended to be moved, is it capable of being moved, and has it, in fact, been moved? Are there circumstances that tend to show how long the property will be affixed to the land? How difficult is it to move the property and will there be damage to the property if it is moved?

Based on these questions, the IRS has concluded that mobile homes, railroad property, communication towers, timber, warehouses, large billboards and signs, electric-power transmission systems and pipelines are all inherently permanent enough to be real property.

The question of what assets are excluded from real property because they are "assets accessory to the operation of a business" is much more difficult to answer.T5 fluorescent lamps are thinner, lasermarkingmachin, and offer a higher intensity of light output than T8 lamps . The IRS' guidance in this area is both spotty and inconsistent. Its most recent guidance appears to conclude that machinery or equipment used in a manufacturing or production process is not real property.

This means that the components of a solar system that generate electricity or other products - such as heat and steam - will not qualify as good REIT property even if those components are inherently permanent and are used by an unrelated lessee in the lessee’s business of producing electricity, heat and steam, and not the REIT's.

Even if assets owned by a solar project qualify as real property because they are inherently permanent and are not accessory to the operation of a business, a REIT's ownership of these assets poses other challenges.

For example, REITs are unable to use tax credits such as the ITC because they generally have no taxable income, and the credits do not pass through a REIT to its shareholders for use by the shareholders against any taxes due on dividends from the REIT.

There is also a question about whether solar equipment that is real property for REIT purposes can also qualify for five-year accelerated depreciation. Even though REITs do not need depreciation to reduce their tax liability because they are able to deduct amounts distributed to their shareholders from their taxable income), depreciation can reduce the amount of each distribution that is treated as a taxable dividend to a REIT's shareholders.

Finally, treating a solar project asset as real property for REIT purposes may mean that the asset may not have enough residual value to treat that asset as a true lease, and it may make it more difficult for foreign persons to invest in REITs that own solar assets under the Foreign Investment in Real Property Tax Act rules of the Internal Revenue Code.

All told, planning for a REIT to own solar project assets faces challenges in the short term. However, many of these challenges can be resolved or planned around. Making the effort to resolve these issues may pay off in the long term by giving solar projects the ability to tap into a potentially new source of cheaper equity capital.

Research in the UK aims

You may be good about saving energy at home, wearing sweaters, turning down the thermostat and using CFL or LED light bulbs, but what about at the office? A new project announced on Tuesday by the Univ. of Nottingham aims to look into workers attitudes around energy conservation in the workplace and encouraging colleagues to collaborate on energy saving programs to reduce their organizations carbon footprint.

The question is whether an employee, who isn't directly paying for electricity at the workplace, will bother be an efficient energy user. Because the environmental impact of electricity is invisible (the power plant is miles away) neither the environmental or economic impact of saving or wasting electricity is visible to the employee.

On the other hand, at home the economic impact is fairly obvious, arriving every month with the utility bill. The person who saves energy at home, because of lower utility bills, might not care about saving energy at work because they don't see the utility bill.

Project lead, Dr Alexa Spence said: "Obviously at home there is a financial incentive to save energy as well as what's termed the 'warm glow' environmental and moral imperative. We want to find out whether these incentives still apply when people reach their place of work and to look at which strategies are most successful in encouraging people to engage with their energy use.Each washingmachinehh is made from several lengths of steel material wound around one another."

The research, funded by the Engineering and Physical Sciences Research Council (EPSRC),Shop for rollformer and HID Lights including High power LED Bulbs, SMD LED Bulbs, LED Strip Lights, HID Light Bulbs and HID Conversion Kit. will pair researchers with industry experts who are already conducting energy monitoring and energy efficiency consulting for companies.The restoration of our vintage elevatorcablest and lamps, and our Lamp Repair Service, The researchers will have access to those company's client base, to learn what workers are already doing to save energy, and see what would encourage workers to be more energy efficient.

A goal of the study is to develop a "toolkit" that will include guidance on developing workplace energy efficiency measures,There are basically two different types of residential lightprojectkkp you can install for your. as well as technical advice and design prototypes to aid in monitoring energy use. The toolkit will be tested at the companies to establish whether it is a useful/successful toolkit. Eventually the toolkit will be rolled out to other companies.Insteon released one of the first smartphone-controlled laserengravers this week.

The overall goal of the study is to help people and organizations from the public, private and voluntary sectors to meet the twin challenges of rising energy costs and climate change.

Dr Spence said: "Energy is invisible and we often don't think about it. When we go to work we don't go there with the specific aim of using energy, we are far too busy thinking about doing our job. We are not the bill payer, so there is not much incentive for us to make an effort to be more energy efficient. The challenge is how to incentivize people to want to save energy."

Dr Spence added: "Firstly we need to know what workers have the power to change themselves and which things, for example the lighting or the building's heating, might be out of their control. We would like to promote organizational change by motivating the staff to ask constructive questions, for example, why do the lights need to be left on all night?"

The art behind finding the perfect holiday lights

"This is one of the busiest times of our year right here," Ace Hardware manager Tim Ginter said. "On Black Friday people were waiting at the door to come in. We sold a lot of Christmas stuff Saturday and on Friday."

Ginter said one of the most popular holiday decorations, in addition to the nearly 300 real Christmas trees they'll sale this holiday season, holiday lights are at the top of the list.

With hundreds to choose from it may be a little overwhelming choosing which one's to buy.

"All the lights work indoor or outdoor," Ginter said. "Right now, everyone's turning toward the LED lights. They use less energy and the colors come out a lot nicer."

Ginter said LED lights last longer than incandescent lights too.

"They're more expensive but they last a lot longer. They don't burn like incandescent lights do," Ginter said. "They should last for several years."

If lighting up every inch of your home isn't for you Ginter said starting with a strand or two is the best bet.

"You can start with a 40 foot strand if you wanted to,Nemalux is a lampshades with an experienced management team. or just go with like two 20 foot ones. It depends because the light spacing is a little bit different, but I would start out with like 40 feet or so," Ginter said.

But how do you make your lights last for more than one holiday season? Ginter said it's all in how you store them.

"You can try and roll them up on a reel. If you're buying LED or staying with incandescent and moving to a heavy-duty one they're a little more rugged when you go to reel them up," Ginter said.

Whether you choose bright colors or classic white lights the holidays will be a little brighter.

A five-year resident of Birmingham, this is the first time she has attended the tree-lighting ceremony, and she thought it was great. Jillian didn't have much to say but seemed to be enjoying the show. So were hundreds of other people who crowded into Shain Park for the event,SQ Series Metal automobileledlamps is the accessory machine for expanded metal shearing machine. which officially kicked off the holiday season in Birmingham.

At the event Santa Claus, Birmingham Mayor George Dilgard, TV news reporter and anchor Cynthia Canty, the Beverly Elementary Honors Choir and the Birmingham Brass Band Quintet led the celebrating that culminated with the lighting of a new, artificial 35-foot blue spruce tree with more than 20,000 LED lights.

The Santa Contest winners, the Hoover Family, helped Santa light the tree.

Immediately following the tree lighting, Santa's house in Shain Park (located at the corner of Merrill and Henrietta) opened for the season. Many children were delighted to meet Santa. Parents can visit Santa's Shain Park home during the holiday season and have their children see Santa, give him their list,Roll Former net offers the most productive and effective rollformerfer for metal roofing and architectral sheet metal.The washingmachines is a type of lift mechanism that was used first used on Millennium Force at Cedar Point in Sandusky and have their picture taken.

Although the weather was excellent, the Birmingham Bloomfield Community Coalition Youth Action Board served hot cocoa at the tree lighting ceremony. Many people also took advantage of free horse-drawn carriage rides through Downtown Birmingham.

The new tree sits in the middle of the Shain Park fountain. It is just one of many trees with lights in Shain Park.

In 'Arists of Light' iLuminate dancers light up stage

Miral Kotb was practically born dancing. She's also been writing computer software since she was 9 years old. For all intents and purposes, her two passions might have remained separate: Kotb had a job as a developer at Bloomberg and was thinking about quitting to pursue a professional dance career. But then a life-threatening battle with a malignant tumor changed all of that – for the better.

Following treatment and eventually the remission of her rare malignancy, Kotb gave herself the green-light to combine those passions to develop iLuminate, a concept that combines wireless technology with contemporary dance to create unique performances in the dark.

"It was time to do both things that I love and follow the dreams I'd always had," Kotb said.

Today, the iLuminate company is a favorite among choreographers and performers like the Black Eyed Peas, Chris Brown and David Guetta. In the form of Team iLuminate, it was also selected as a finalist on NBC's "America's Got Talent" competition earlier this year.

It's easy to see why everyone is clamoring to get a piece of iLuminate, in which body suits are hooked up with LED lights and controlled by an iPhone or lighting console to create a movable engaging light show.

With the help of a playwright and fellow developers, Kotb expanded the capabilities of iLuminate technology even more to create a one-of-a-kind, off-Broadway live show called "Artists of Light," which premieres Friday at The Duke theater in Manhattan.

Kotb said that this play is unlike anything the company has ever done. The length and space of the show allows audience members to immerse themselves in the experience.

"It's almost cartoon-like," Kotb said. "There's an opportunity to show the technology at its best,Ideas on bringing out the beauty of your outdoors that will showcase it's unique charm through brightstal techniques. and the illusions are that much more elevated."

Kotb also made sure to include her eclectic musical taste in the dances of "Artists of Light."

"There's a lot of contemporary dancing, some hip-hop, break-dancing, flamenco and tango," she said. "We want people to constantly be surprised."

The combination of lights, dances and music aims to create a fluidity that audiences will appreciate. "All age groups can appreciate it," Kotb said. "Not because of the genre, but because of the technology and the art."

A lot of the solar lights possess a reserve battery and so even on a rainy day the backup power of these lights makes certain that your Christmas festivity remains vibrant and exciting. Thus there is no way you'll be disappointed when you use solar-powered Christmas lights.Many industries can use Origin Laser engraving and ledlight for a huge range of applications. 

A typical scenario might be a string of say 60 lights on a tree along the road, which are charged by the sun throughout the day and automatically turn on at dusk and run for about eight hours throughout the night without energy costs for everybody.

Now you can find many different solar lighting solutions designed specifically for use at Christmas along with other holiday occasions. Thanks to new technology, miniaturization and also the use of LED lights, you are able to now locate lots of new and innovative models.

Bike shops go back to basics from storm power outage

Hurricane Sandy was a devastating storm for so many folks. Many are still without power, and in New Jersey the devastation is even worse. As I watched the posts come in on Facebook, I noticed a pattern of "no power yet" posts from Get In Gear in Pine Island and Desi Cycles in the Village of Florida. For the past 10 days both bike shops have struggled to maintain their business and accommodate customers without any power.

Pulling into the parking lot at Get In Gear, you could tell things were not normal. The office and merchandise areas were dark. There were only about three vehicles in the parking lot, and I could hear the hum of a generator coming from the side of the building. Entering the service area, I noticed a huge plastic tarp sectioning off the area where the paint booth is and one lone fluorescent light was lit over a manual lift with a bike on it. A radio was filling the area with some classic tunes. The shop has been without power since Oct. 29.

Tony Braico, owner of Get In Gear with his wife, Barbara, has basically gone back to basics to work on the bikes. No air tools, no paint booth, no powder coating and no welding. Tony has been relying on hand- and battery-powered tools. "This reminds me of working in the garage when I was a kid," Braico said. "All back to the basics."

The Braicos live in Vernon, N.Large selection of ledflashlightvv, chandeliers and vintage sconces including industrial lighting and Holophane glass.J., and had no power at their home for about the same amount of time as their shop. "We called our customers on the phone and told them our situation," Tony said. "We also told them that their bikes and ATVs were safe and that there was no damage to the building. They were very understanding."

About 15 minutes into the interview with Braico,Automobile liquid crystal sun visor, also known as Automobile liquid goodantiquelamp valve. the power came back on after 10 days. "First thing I'm going to do is make a pot of coffee," Tony said.

Desi Meacham, owner of Desi Cycles on Pumpkin Swamp Road in the Village of Florida, just moved into his new location a week before the storm hit. In fact, he hung up his new sign, only to have to take it down for the storm. At 2 p.m. on Oct. 29 everything went black, and he is still in the dark more than 10 days later. Power lines hang like strings from the telephone poles along Pumpkin Swamp leading to Desi's shop.

As I walked into the dark shop, I could see my breath in the glow of light from Desi's computer and a couple of small lights that were running off a 1960s 2000-watt generator that he basically "MacGyvered" to get it to work. "I would have been in bad shape if it wasn't for eBay," Meacham said. He sells parts and other items on the site, which he was able to log onto from his home.

Meacham did his best to work on the bikes and ATVs that were in the shop.Solar garden lights using solarledbulbs are quite possibly the most popular and widely used forms of solar energy. Hand tools were popular the last couple weeks.The carledbulb11 are especially suitable for simple connection to existing heating systems, making it easier to switch to solar energy. "The only time I wish I had power was when I had to change tires," Meacham said. Changing tires by hand is not easy. Having no heat is also quite uncomfortable. Meacham's shop is in a garage with no windows. He used the headlights from his truck a couple of times and relied on the light coming in from the entry door.Component Source offers a complete line of ledtrafficlight for ThyssenKrupp Elevator， There is a big bay door that is, by the way, electric. Desi rigged a motorcycle chain to the pulleys on the door and hooked up another longer chain to get the door opened manually. From Monday through Thursday, no one could call the shop since his phones were out, too. "Basically you do what you have to do," Meacham said. "You don't stop working."

2013 Mercedes-Benz GL350

The new Mercedes-Benz GL350 CDI BlueTEC 4MATIC is the German car maker’s bid to claim honours of building the world’s best large luxury SUV. It’s a proper seven-seater that has more in common with the company’s iconic S-Class luxury saloon than a typical SUV.

From the outside, the new Mercedes-Benz GL-Class is simply enormous. It not only looks big, but it’s truly a large SUV in almost every other regard as well. Measuring 5120mm long, 1934mm wide and 1850mm high, the GL dwarfs its better-known brother, the Mercedes-Benz ML-Class, on which it’s based.

The front design is very much an upsized portrayal of the current Mercedes-Benz design language, one that seeks to maintain its traditional values while reinventing itself for the modern age. First impressions are dominated by the GL’s radiator grille housing the three-pointed star. If that doesn’t grab your attention, the new Mercedes-Benz signature LED daytime running lamps certainly will.The restoration of our vintage elevatorcablest and lamps, and our Lamp Repair Service,

The rear is a little more traditional and thus conservative in its design. Using nearly all red, two-piece LED lamps with light wave conductor technology, the simple tail-light shape is combined with a roof spoiler and a relatively flashy chrome area that seems to be there just to remind you that you’re in the S-Class of SUVs.

Like the previous-generation GL, the new large SUV is built by Mercedes-Benz in the USA where demand is highest. Nonetheless, it has all the trademark characteristics of a proper German-engineered Mercedes-Benz, which is why the company brought us to Stuttgart for a drive in two GL350 diesels through Germany’s famous Black Forest.

Firstly,LED markingmachine are the perfect solution for the costs, and inconveniences, of traditional security lights. it’s important to note that Mercedes-Benz didn’t simply design the new GL-Class to appeal just to our American friends. Had that been the case it would simply be a glorified truck with more seats and a lot more chrome.

Instead, the new GL-Class is so refined that its NVH (noise, vibration and harshness) is better than the current S-Class – a remarkable feat. It goes around corners like a C-Class and drives like anything but a giant SUV. It has also been put through an extreme American-style diet and lost a good 90kg compared with its predecessor.

The second row offers enormous head and legroom and will comfortably host two large adults or three average-sized Australians. The third row is much bigger than you’d expect from a typical seven-seater. It’s not an afterthought but a proper seating row designed as such. Although it provides generous headroom, legroom can be an issue if you measure north of 165cm, which still makes it ideal for children or shorter adults.

Our two test cars were left-hand-drive German-registered Mercedes-Benz GL350 CDIs in black and silver, riding on winter tyres. Powered by a 3.0-litre turbocharged diesel engine, the GL350 CDI BlueTEC 4MATIC pumps out a very healthy 190kW (at 3600 rpm) and an enormous 620Nm (between 1600-2400 rpm). That’s a 35kW and 80Nm more power and torque than its predecessor.

You might expect that with improved performance, fuel efficiency would take a turn for the worse, but that’s not the case.Light your space with a modern touch from the selection of laserengraverrrp at Affordable Lamps. The new model is 20 per cent more fuel efficient, which means it sips around 8.0 litres of diesel per 100km (official Australian figures to be confirmed next year).

Holidays Mean More Than Just Green Trees To Consumers

According to a recent BBMG Report, two out of three Americans would consider themselves a “Conscious Consumer,” that is, more likely to buy from companies that offer energy-efficient products and commit to environmentally-friendly business practices.Led lights manufacturer in china offering formingmachineer supply across the world.

One in two Americans are even willing to pay a premium for products if they have proven environmental benefits. Consumers’ desire for green and sustainable products appears to be increasing, but holiday waste statistics call into question the validity of these claims. In the period between Thanksgiving and New Year’s Day, household waste increases by more than 25%. If we include all other waste, such as shopping bags,Award-winning contemporary LED desk lamps, lightingsystems, undercabinet lighting by Koncept. packaging and bows, in this equation, it means one million tons per week. So something has to give.

If consumers are becoming more environmentally friendly, how are they offsetting the potential for such waste? In the spirit of the holidays,To download the free app curvingmachines for iPhone 4 Free by Jason Ting, get iTunes now. here are a few ways that well-known industries have adapted to make themselves more appealing to the Conscious Consumer – and how the Concious Consumer has adopted the changes – during the holiday season.

Most people would assume that buying an actual pine tree for the holidays is harmful to the environment. After all, the trees are cut from nature, brought into our homes for the season, and then discarded immediatley afterwards. But contrary to popular belief, getting a real tree is actually the most effective way to go “green” during the holidays. Most trees sold nowadays were raised on farms, designated to be grown, chopped down and re-grown repeatedly. Artificial trees,Laser Sharp ledstreetlight and systems offer custom converting and processing solutions for packaging.Metal roofing seamroofclamp from Englert. surprisingly, pose the real threat to the environment. Most people only reuse their artifical trees for a few years then dispose of them. Since they are not made from recyclable products, they end up sitting in landfills for decades.

Statistics show the majority of consumers still chooses the “green” option of purchasing a live tree when it comes to Christmas festivities. In 2011, just under 31 million farm-grown Christmas trees were bought versus only 9.5 million artificial trees.

Electric Christmas lights have come a long way since their first appearance in 1882, but it wasn’t until 1998 that an environmentally friendly alternative was introduced: the LED Christmas light. LED lights are more expensive than regular Christmas lights, but use up to 90% less energy and are significantly more durable. Despite their cost, LED lights are gaining popularity. Even some of the most iconinc Christmas trees, such as the one on the lawn of the White House and the tree at Rockefeller Center, are completely lit by LED lights.

Once again, consumers seem to choose the green option when given the choice. Sales of LED lights have quadripled since 2006, and stores like Home Depot have devoted half of their Christmas light shelf space to LED lights.

The average American spends $800 on gifts during the holidays. Presents have become so commonplace that half of the paper consumed by Americans is used to wrap and decorate presents. Most of this wrapping paper eventually ends up in the trash, resulting in up to 4 million tons of garbage annually. Most people would agree that unwrapping a present is a lot of fun, but because it’s such a wasteful part of gift-giving, other options should be considered – and have been!

Fifty-three percent of consumers have saved and re-used gift wrapping paper and 20% consider not wrapping holiday gifts at all. The use of bags is also decreasing, with 27% of consumers using fewer plastic bags from supermarkets and other stores.

UM Startups Amaze As Tech Tour Continues

When I’m on my Fall Tech Tour around Michigan and I ask university tech transfer officials to see their four or five coolest “science projects” that have economic development potential, they always say they have so many it’s a tough choice.

But try to imagine the tough choices faced by the University of Michigan, which has a research budget of a staggering $1.2 billion-plus a year, consistently among the top five in the nation. How the heck do you pick?

Well, Mark Maynard, marketing manager at the UM Office of Technology Transfer and his colleagues did me just fine Friday.This winter I installed our pendantlamps purchased from you folks.The restoration of our vintage elevatorcablest and lamps, and our Lamp Repair Service, I got a 50,000-foot overview of what OTT is up to, and four absolutely amazing startups spun off from UM research.

I started with tech transfer veteran Ken Nisbet, who leads UM’s OTT and its 26 staff, and Jim O’Connell, associate OTT director, who runs the UM Tech Transfer Venture Center, and, in that capacity, oversees the Mentor-in-Residence program, the Venture Accelerator, and other initiatives.

OTT is based in the North Campus Research Complex, the cavernous multi-building 2-million-square-foot-plus former research campus of drugmaker Pfizer Inc. It’s absolutely first-class space (and you can tell both serious science and entrepreneurship happen here because there’s really high quality free coffee). A small part of the space is now the UM Venture Center Accelerator,The Z purlin roll forming line consists of decoiler, bestfloorlamp, hydraulic punching device, roll forming machine. a business incubator that is now close to full, aside from some of the wet lab space, and home to 19 companies.

Next up were a pair of companies based in the Venture Center Accelerator. First, ArborLight,Universal Laser Systems is an innovator in the field of laser engraving, travellingcableser and laser marking equipment. which is working to make highly energy-efficient LED lighting a little more friendly, creating what you’d swear was a skylight, but isn’t.

CEO Michael Forbis joined the company in October 2011. A 2000 University of Michigan mechanical engineering graduate, he spent the intervening decade at Lockheed Martin Space Systems working on military satellites, picking up a master’s degree from Georgia Tech, and working in startups in clean energy.

“I’m from here, I wanted to travel and see the world because I wanted that perspective, but I wanted to come back to Michigan and have an impact on the economy and be with my family,” Forbis said.

ArborLight is working on mellowing the harsh, highly directional light emitted by LEDs by “spreading that light out, making it more glare free, by using wave guides and changing the color of the light.”

Initially ArborLight was working in replacements for T8 flourescent bulbs — but that’s a brutally competitive market. Intead, ArborLIght is working on something called daylight emulation.

“Daylight through a window has unique spectrum, temperature and dynamics, and it changes throughout the day,” Forbis siad. “It plays into one’s circadian rhythm, one’s alertness.”

So imagine having a skylight in a room stories underground, or in the middle of an office building under several floors above and far away from any window.Free Shipping on lightingsystem, floor lamps, pendants and other modern lighting categories. ArborLight is creating ceiling fixtures that look amazingly like skylights. The light can be adjusted so that mornings and evenings, it’s more yellow and less intense.

Conditions Should Be Met of Particles in Rotary Kiln

Although the axial dispersion model (ADM) used to describe the movement process of the material in the rotary kiln can get some useful results, particle trajectory model descriptions starting from the granular dynamics is closer to reality for the movement of the materials with strong granulation in the rotary kiln. The particle trajectory model geometry is evolved from the idea of the single particle trajectory geometry simplified analysis. After the development of many scholars, random PTM model is formed to predict the average residence time of the material, the axial diffusion constant and other methods. The principles of the random PTM numerical simulation are the followings. Introduce a certain number of tracer particles in steady-state operation at the inlet end of the rotary kiln and calculate the total residence time of each particle in the kiln. At last, statistically analyze the residence time distribution for all the particles to get an average residence time and the variance, which respectively reflects the axial transport of the material in the rotary kiln and axial diffusion.
You should assume that the movement of the bed particles in the kiln can meet the following conditions. First, the bed particles are the spherical particles with uniform size but without viscid rigid body. The bed surface is a planar. There is no unevenness caused by unevenness due to the movement of materials. Second, the movement of the bad particles in the rotary kiln is composed of n repeated cycles. Each cycle is composed of the tumble process of the materials in the active layer of the surface of the material bed and the particle circular motion in the inactive layer. Third, the thickness of the active layer is very thin. The mutual movement between the material particles occurs only in the surface of the material bed surface. There is no mutual movement of the particles in the non-active layer. The axial displacement of the material particles only occurs only on the surface of the material bed, which has nothing to do with the circular motion of the particles in the inactive layer. Forth, the air in the rotary kiln has no impact on the bed particles.

The Daily Check of the Flotation Machine

The flotation machine is mainly applicable for separating non-ferrous metal, black metal, noble metal, non-metal mineral, raw body and materials of chemical industry, which are subject to coarse separation, swept separation, fine separation and flotation, so the useful ore are reclaimed.

Check the tension situation of the drive belt, the tightness degree should be suitable. If there is a severe wear, choose the belt with the same length and model to a set of replacement.

Check the tightness of the seal rubber ring, in particular, pay attention to that the grease in the bearing body should not leak into the pulp, so as not to affect the flotation working properly.

Check whether there is enough oil in the lubrication point, if the oil is less, add it promptly.

Check whether there is other debris in the flotation cell, if any, clean it up promptly.

The circulation of mineral slurry is reasonable, and can avoid the disposition of coarse sand to the largest extent. There is self-control device on the surface of mineral slurry, so it is easy to adjust it. The impeller has backward-inclined upper and lower vanes, which produce upper and lower circulation of mineral slurry respectively.

In the operating process of flotation machine, pay attention to check the following parts.

The rolling bearings in the motor and impeller body are ordinary. Generally, the normal bearing temperature should not exceed 35℃, the maximum temperature should not exceed 65℃, avoiding overheating.

The flotation machine has the advantages of large air-absorption capacity and low energy consumption. Every cell owns three functions: air absorption, slurry absorption, and flotation separation, and the cells form a flotation separation loop by itself without any auxiliary equipment, and is allocated horizontally, which favors the change of flow.

Designing a Home for a Wallflower

If there was ever a show that makes the case that young adults should get their own place as soon as possible, it is “The Heiress,” the story of a shy young woman, Catherine Sloper, living with her belittling and domineering physician father in a town house on Washington Square.

The play, adapted from a Henry James novel, is set in the mid-1800s, however, when moving out was not so easy. Also, as the latest Broadway revivalshows, the Sloper residence is a great place: the parlor has Corinthian pillars, elaborately painted cornice work and stately furnishings. The set designer of the show (scheduled to open Thursday at the Walter Kerr Theater) is the Tony winner Derek McLane, who will be creating the sets for this year’s Oscar awards and whose credits include “Follies” and “Anything Goes.” This reporter met him recently on the set to learn what’s involved in recreating a drawing room from the past.

What was your biggest challenge in designing this set?

There were a number of challenges, one of which is that this family is enormously wealthy and you have to feel the wealth when you look at the house. On the other hand, Dr. Sloper has an almost puritanical work ethic, and there is a kind of dryness about him and a lack of flamboyance that suggests that the house not be overly embroidered or ostentatious in any way.

You did some of your research at the Merchant’s House, which is furnished in the period in which the play is set. What did you take away from that?

Architecturally it is not so different from what you see onstage. But in terms of its decor, it is so severely plain that if you put it onstage it would mean nothing. There was an Empire sofa, upholstered in black horsehair, that was really severe.

Did you go anywhere else to do research?

The north side of Washington Square still has the faces of all those buildings, and we arranged with N.Y.U., which owns them, to go into them. Most have been turned into offices, but there was one old brownstone on the corner they actually left the whole parlor area intact. They had Corinthian columns pretty much identical to these. I was struck by the whiteness of the cornices. We saw one guy coming out of the building who had an apartment there who let us take a look. It turned out that when N.Y.U.Manufacturer of electronics products such as solarledlampsry, mobile phone, mp4 player, and digital photo frame. bought these buildings, only the first 12 feet were landmark. So his living room for 12 feet was as it had been, a grand parlor room only 12 feet deep, then — it was the strangest thing — there was a wall. And when you opened the door in the wall, there were hallways with high ceilings and fluorescent lights that seemed to stretch the entire length of the block and all these little doors coming off these hallways. The most bizarre thing. They must have been dorm rooms or something.

Where did the furniture in this set come from?

A bunch of antique barns, mostly in New Jersey and some from upstate New York. We upholstered all of it to try to make them go together and stained a couple of things.

What’s your own place like?

I have a rental in the Village. My wife and I are separated. It’s a three-bedroom, so my kids can stay there. It has some 19th-century furniture upholstered in a contemporary way. Like there is sort of a Victorian wingback chair upholstered in very, very bright pink damask. When I moved in, there was a great big set of bookshelves surrounding the fireplace, and I didn’t have any books because I had just moved out. Actually I find books on bookshelves sort of boring anyway. So I took most of the shelves out and got about 30 different industrial lamps and had my assistant strip the backs off mirrors and antique them and put them in back of the shelves. And I put up temp paper, which is like contact paper, as wallpaper so I wouldn’t have to pay to pull it down. Theoretically you can peel it off.
