Forklift - ROCHESTER, N.Y. (AP) – Seven mechanics at Xerox Corp.’s manufacturing hub in upstate New York have been charged with helping to bilk the printer and copier maker out of an estimated $4 million for forklift repairs that weren’t carried out.
Federal prosecutors say four current and three former employees who maintained Xerox’s Forklift Truck fleet in suburban Rochester sent out parts to an electrical company for repair between 2002 and 2007. They say Clarkson Auto Electric in Clarkson near Rochester simply repackaged the parts and sent them back.
An internal investigation was taken up by federal authorities in 2007.
The mechanics, and three Clarkson Auto owners, were charged with mail fraud and conspiracy. If convicted, they could each draw up to 20 years in prison.

Better safe than sorry. The Refrigerant closed the Towne Center Shopping Center on South Glynn Street late Sunday afternoon after a coolant line broke at the Kroger supermarket. The center was cleared for opening later Sunday night.
The shopping center was closed at approximately 6 p.m. after the fire department received a 911 call from store employees. Fire department spokesperson Bill Rieck said the break in a refrigerant line came from a piece of portable equipment in the deli area. The Refrigerant has the potential to be explosive, Rieck said.
Firefighters followed Georgia Environmental Protection Division regulations and allowed for the coolant to be ventilated, said Rieck. The Kroger and adjacent businesses were evacuated.
Firefighters and police blocked entrances to the shopping center until ventilation process had been completed.

The Colchester-based specialist Fleetshield Services fitted its 2.7-tonne Vitos with custom racking for tools and spare parts, and carriers for bottles of refrigerant gas.
WR Refrigeration financial director Paul Brown says the company switched to Vitos in 2006, and that the new vehicles are part of its replacement programme. Another pair of Mercedes-Benz vans, both 3.5-tonne Sprinter 313CDIs, are also about to enter service, he says.
“Those first vans performed very well and, while this model already accounts for the greater part of our 450-strong service fleet, our aim now is to become an all-Mercedes operation at the earliest opportunity,” states Brown.
Key to the appeal of the Vito, he says, is its active and passive safety systems, which include the latest adaptive version of the ESP anti-skid system.
WR Refrigerat new vehicles are the subject of a four-year lease with the in-house commercial vehicle finance arm, Mercedes-Benz CharterWay. Responsibility for overseeing the maintenance of the new vans has been assigned to Daimler Fleet Management, the fleet Kitchen Cabinet Door provider of Mercedes-Benz parent, Daimler.
“Our engineers are our most important asset so we’re always conscious of our duty of care obligations,” says Brown. “They enjoy driving comfortable, well-equipped vehicles, especially the new 111CDIs which, with their 116hp engines, are more powerful than the 95hp 109CDIs they’ve replaced.”
And he adds: “This is our first experience of Mertrux as a supplier and I have been very impressed with the dealer’s professional approach. The same is true of Mercedes-Benz CharterWay and Daimler Fleet Management.”

When it comes to performance measurement and air conditioning systems, most master technicians gravitate to one of two measurement techniques, the airside or the refrigerant side.
Refrigeration experts will challenge anyone that questions pressure and temperature measurements on the refrigerant circuit as the only legitimate methods of determining equipment performance. On the other hand, an experienced airhead will fight to the death to defend his belief that airflow, pressure and temperature testing will deliver superior performance every time.
So who’s right? Both are fluids, both transfer heat and are essential to the performance of a system. The truth is an individual who has mastered both the air side and the refrigerant circuit will prevail every time when it comes to measuring air conditioning performance. Let’s take a look at each method and consider the best of both worlds.
Refrigerant Circuit Measurement
There has been substantial focus over the last few years on the refrigerant measurement and diagnostic practices in utility and government programs. They’re called RCA programs (Refrigerant Charging and Airflow.) Several amazing new refrigerant instruments coupled with software such as the Service Assistant and the Testo 523 are leading refrigerant diagnostics and performance into the 21st century.
These instruments calculate super-heat and sub-cooling values based on a wide scope of refrigerants and provide troubleshooting solutions that experienced technicians would take years to master. Equipment performance can be calculated and Shower Room are built into the software.
However without the 400 CFM per ton airflow over the indoor coil being verified, current refrigeration tables provide little help. Also, unless data is available from the manufacturer that matches current indoor and outdoor conditions, interpretations of refrigerant test numbers remain questionable. There are heated discussions as to whether or not these instruments can accurately determine airflow through the equipment.
The primary concern is that the refrigerant circuit is limited to equipment performance. Duct system losses outside that circuit are invisible from this diagnostic portal.
Airside Performance Measurement
Airside measurements, if they include airflow, pressure and temperature can be effectively used to interpret the performance and efficiency of the entire system. If these values are applied to effective system performance formulas, they can open wide new diagnostic doors and provide efficiency solutions.
One sure win for the airheads is that the air system measurements look beyond the box and see the performance of the entire installed system, not just the operation of the equipment. The idea that the equipment efficiency is the definitive measurement of energy savings should have died years ago.
On the other hand, airflow measurements, like refrigerant readings can lead you down the wrong path. Airflow measurement without temperature measurements that ignore the performance of the refrigerant system can draw an incomplete picture about efficiency.
High Tech Solutions for Low Tech Problems
Jim Brown, of Mountain Home Arkansas, once taught me the weaknesses of using high tech solutions to solve low tech problems.
One risk of solutions gained using today’s high end technology is that we assume the makers of today’s technology are capable of leading us to the best solution every time. The best solution is to have all the high tech tools and know how to use them, but then to have the knowledge and wisdom, gained through experience, to bring the entire system and its performance into a single efficiency rating.
While we’re at it, we cannot forget the HGH. How can efficiency be achieved without testing and adjusting the combustion circuit along with the airside?
One of the weaknesses in our industry today is code compliance attempting to force slices of efficiency together by applying disjointed test methods and slivers of engineering practices in an attempt to create efficiency for consumers.
Just like the refrigeration circuit cannot deliver efficiency independent of airflow testing, we’re fortunate to have a test method that sees the entire system and its performance as a whole.
After years of progress in measuring the performance of HVAC systems, it seems we are just beginning to see the value of a single system performance rating number that assures all the factors are considered when declaring the installed efficiency of an HVAC system.
The answer is for air conditioning system performance is using both airside and the refrigerant side measurements to maximize system performance.

The lips can be enhanced by creating more lip volume to thinner lips to give them a fuller appearance. Dermal filler can be injected along borders of the lips and into the cupids bow to accentuate the lip line giving a more shapely and youthful appearance.
Marionette lines are lines that are present just below the corners of the mouth and occur with loss of volume associated with ageing. They can give the appearance of pulling the mouth downwards giving a sad and unhappy facial expression. Dermal filler can be injected just below the corner of the mouth to soften these lines by adding volume to the area and giving shape to the lips. Smokers lines which are vertical lines mainly at the top lip can also be effectively reduced by dermal filler treatment into the lips.
The cproduct used at Face Clinic London is Restylane which is the most scientifically documented dermal filler in the world with over 10 million treatments worldwide, they are safe. All treatments at Face Clinic London are administered by fully qualified doctors who aim to give a subtle and natural look.
Face Clinic London only use dermal filler products with the local anaesthetic Lidocaine included for a more comfortable treatment experience. The treatment itself takes about fifteen minutes and the results are visible instantly. There may be small amount of swelling after the procedure which usually settles. The effects can last for about six to nine months after which the filler dissolves naturally in the body and the lips return to how they were before treatment.
