TRACERCO Diagnostics

1/5/2009 · Kategori: Teknoloji

Do you want an installed method of regularly assessing the operation of your distillation tower, reducing operating costs and reducing shutdown time?

To meet the changing needs of our customers the Tracerco research and development team has designed an alternative technique to conventional tower scanning. The TRACERCO Diagnostics™ RapidScan technology combines sophisticated wireless detector capability with an easy to install permanent scanning guide wire system.

The TRACERCO Diagnostics™ Tower Scan method has been used for over 20 years by many major chemical and refining companies around the world. The combined data acquisition software from these techniques coupled with TRACERCO Diagnostics™ RapidScan hardware increases efficiency and reliability of scan data by providing fast, consistent data acquisition from fixed orientations. The service allows repeatable tower scanning that can quickly evaluate mechanical or process related problems offering plant personnel a cost effective process diagnostics solution to optimize or troubleshoot tower performance. Even columns with limited or zero ladder access do not pose an obstacle following installation of a TRACERCO Diagnostics™ RapidScan system.

• Improved Accuracy - the scans will use a fixed orientation so repeat scans are guaranteed to utilise identical geometries
• Better Data Reliability – data will not be affected by weather conditions (wind)
• Increased Safety – all scanning operations will be from ground level with no need to climb the tower, eliminating workingfrom heights
• Greater Cost Savings – after initial setup, the high costs of scaffolding or cranes for columns that have inadequate or no access is eliminated
• Enhanced Efficiency – reduces time needed to conduct a scan lessening the burden on operations to hold column at set conditions

The capabilities of conventional tower scanning are not lost. In fact, the TRACERCO Diagnostics™ RapidScan system potentially improves our ability to diagnose more subtle process changes by stringently controlling and eliminating variability in scan line orientations and paths.

Features Identified

• Tray damage
• Liquid maldistribution/blockages in packed beds
• Tray liquid loading
• Jet and liquid stack flooding
• Packing damage
• Distributor performance
• Presence and density of foam

All of the stainless steel pulleys and bracket work will be attached to the existing structure using insulation bands utilising the ‘band-it’ system. No welding or direct attachment to the column walls is required; hence the vessel pressure envelope will not be affected.

DDR-150 Rotary Positioning Stage

27/4/2009 · Kategori: Teknoloji

Direct drive brushless DC servo motor

• Precision ground ABEC-7 4-point contact bearings
• Durable stainless steel top plate with through hole
• Resolution to 0.2 arc seconds
• Highly repeatable Hall effect home and limit switches
• Optional encoder scale cover
• Ideal for:
  • Wafer Inspection
  • Precision Assembly
  • Laser Machining

Low Profile Direct Drive Rotary Stage

The direct drive servo control of the brushless DC motor has several advantages over conventional gear driven rotary stages. Backlash is eliminated, torque variation is minimized, plus gear and brush wear are no longer factors in long term usage. Added benefits include speeds up to 360 rpm, 0.2 arc second resolution and ±1 arc second repeatability. Step-and-settle time is also reduced due to increased servo bandwidth.

Available options for the DDR-150 include a variety of encoder resolutions to meet your speed and accuracy requirements. An axial through hole for use with pneumatic or optical devices; adjustable home, limit and hardstop positions; and a sheet metal cover to protect the encoder and internal components.

Sarmısak Çayı

22/4/2009 · Kategori: saglik

Doğum sonrası kilolarından kurtulmak isteyen seksi yıldız Angelina Jolie, 'sarmısak çaylı' diyet uygulamaya başladı. Doğum yaptığı Güney Afrika ülkesi Namibya'da sağlık gurularının tavsiye ettiği sarmısak çayını yanından ayırmayan Jolie'nin yakınları, güzel oyuncunun doğum sırasında aldığı 11 kilodan hızla kurtulduğunu söylüyor. Jolie'nin uyguladığı diyet programının merkezinde bulunan sarmısak çayı Meksika ve İspanya'da soğuk algınlığı tedavisinde kullanılıyor. Ancak çayın, bağırsakları çalıştırarak zayıflamada etkili olduğu da söyleniyor.

İŞTE MUCİZEVİ TARİF...

Bir çok yönden sağlığa yararlı olan sarmısak çayın malzemeleri ve hazırlanış tarifi: Bir tencerenin içine 3 bardak su ve 3 diş sarmısağı atın ve kaynatın. Su kaynadıktan sonra yarım bardak bal ve yarım bardak limon suyu ilave edin, soğumaya bırakın. Günde 3 kez ılık olarak yarım bardak için. Bir sonraki gün kullanmak içinse, kaynattığınız kabı buzdolabında saklayabilirsiniz

Robotic suit helps paralyzed walk

19/4/2009 · Kategori: saglik

LONDON, England (CNN) -- A new robotic suit could transform the lives of paralyzed people, giving them the ability to walk again.

The invention, known as ReWalk, acts like a kind of exoskeleton. It consists of lightweight, motorized leg supports and an assortment of intricate motion sensors.

Users wear a backpack that holds a computerized control box which helps the medical device recognize when a step needs to be taken.

"Standing changes my whole environment. I don't have to look from the bottom up. Now I am eye to eye with everybody," Radi Kaiof, who has used the device, told CNN.

Kaiof, a former Israeli soldier, was paralyzed from the waist down 20 years ago. He doesn't have feeling in his legs but is still able to move with the use of the robotic suit

With the assistance of crutches, which offer balance and support, people paralyzed from the waist down can walk, bend, sit and even climb stairs when they wear the suit.

The futuristic invention offers an alternative to using a wheelchair for those who have functioning upper bodies and are capable of standing with the use of supports.

It is the creation of Dr. Amit Goffer, an engineer and founder of Haifa, Israel-based high-tech firm Argo Medical Technologies. Goffer was inspired to create the device more than a decade ago after he became disabled in an accident.

The medical technology that could help paraplegics do what was once considered impossible isn't available for purchase yet. The device wasn't ready for testing until late 2007 and currently is in clinical trials in Tel Aviv.                     

More trials are planned for the United States and Europe, and if the product receives the necessary approvals, it could hit the market in 2010.

The price of the device hasn't been set yet, but is expected to be comparable with the typical average yearly expense of using a wheelchair.

The robotic suit improves the quality of life of people paralyzed from the waist down, according to Goffer, who wanted to give paraplegics an alternative to using a wheelchair. It also benefits their overall health since it keeps their bodies active all day long, he says.

But when it comes down to it, the invention is all about helping people regain respect. Dignity is "the No. 1 problem" for people who use wheelchairs, says Goffer.

For Kaiof, the former soldier, the robotic suit has changed his life. Before he tried it on, his daughter had never seen him stand before.

When he stood before her for the first time, she couldn't believe just how tall he was, he recounted to CNN.
