Management by mythology
Life is full of mystery. Consider, for example, the mystery of how we got to the point where executives are paid a king's ransom to run companies into the ground and sell off assets. Equally mysterious is why there is a thriving business in management consulting. As former consultant Matthew Stewart puts it, "How can so many who know so little make so much by telling other people how to do the jobs they are paid to know how to do?" Stewart is in a position to ponder this question. He was once one of those highly paid consultants and wrote a book called Management Myths about his consulting escapades. He admits that when recruited fresh out of school, he knew basically nothing about business — his degree was in philosophy. He says his consulting work involved "considerable on-the-job training, all at the expense of large financial institutions who, for reasons that are sometimes difficult to articulate, sought my ....advice on matters having to do with their business strategy."

You/ve been sued. Now what?
The time to prepare for a possible product-liability lawsuit is early in the product design. To defend a product in a liability case, you must convince a jury of technically unsophisticated people that you did everything in your power to design, manufacture, and sell a safe product. This means you must possess detailed records of the product design and manufacturing. Also, you must be able to show that advertising, labeling, warnings, and instructional literature is correct, detailed, thorough, and completely understandable to potential users. Read more

Embedded electronics for the smart grid
Late last month, appliance maker Whirlpool got a big check from Uncle Sam. It wasn't a tax refund. Rather, it was part of $34 billion in federal funds designed to accelerate deployment of smart electric grids. The development that makes such measures possible is the smart electric meter, or e-meter for short. Proposals funded in the stimulus package include plans to deploy about 18 million e-meters, some of which will act as home-communications hubs. Read more

Brass versus stainless
Assemblies made of plastic or other soft materials often rely on threaded metal inserts to secure fasteners and reinforce joints. Though stainless steel may be appropriate for use in some applications, brass inserts can satisfy the majority of performance requirements while offering significant cost benefits. Raw material costs for brass and stainless steel are typically similar but the cost of machining stainless steel is much higher. Free-machining stainless steel may only be 40 to 50% as efficient to machine as brass. Other austenitic stainless steels may be less than 40% as efficient to machine. Read more

Featured video: The space elevator competition
The space elevator contest requires entrants to build machines that climb 2,953 ft (nearly 1 km) up a cable slung beneath a helicopter hovering nearly a mile high. In recent competitive heats, entrant LaserMotive's vehicle zipped up to the top in just over four minutes and immediately repeated the feat, qualifying for at least a $900,000 second-place prize. The device is a square of photovoltaic panels about 2 X 2 ft and topped by a motor structure and thin triangle frame. Physorg.com recently ran a rundown on the contest results and video. Read more

New Products

Diaphragm pump
The new 1410 Series dc miniature diaphragm pump is designed with a full range of motor options and several design configurations to meet application requirements. The pump features a low sound level, is lightweight (0.4 lb), has a 4.3-lpm maximum flow, 27.5-psig/1.9 bar maximum pressure, and a 22.0-in. Hg maximum vacuum.
More Information: Thomas Products Div., Gardner Denver Inc.

Servo rod-style actuator
The new integrated-motor actuator (IMA) combines a servomotor with a rod-style actuator. The IMA's integrated design provides higher dynamic performance by eliminating the need for separate motors, couplers, motor mounts, gearing, and belts. The actuator provides up to 2,000 lbf of force, high speed (23 ips), ±0.00984-in.positional accuracy, and comes in incremental stroke lengths from 6 to 18 in.
The IMA is offered with multiple ball-screw leads and a choice of motor winding voltages. A patent-pending screw lubrication system allows for easy relubrication without disassembly.
More Information: Tolomatic Inc.

Slit-type plastic couplings
A new series of slit-type plastic couplings feature UV resistance, and voltage and RF isolation. The S50TLC... Inch and Metric Series come in sizes 13, 19, and 25. The lightweight molded coupling replaces stainless/aluminum slit-type couplings with low cost and improved operation. There is no windup, backlash, or derating for reversing applications. A metal screw-to-metal nut design ensures a tight fit between the shaft and coupling and does not use threads cut into the molded piece.
Made of engineered polymer with stainless-steel fasteners, the couplings come in 0.125 to 0.500-in. bore sizes and range in length from 0.710 to 1.400 in. Their maximum temperature range is –4 to 284°F.

Selection and Application of Lubricants for Linear Motion
Sponsored by Thomson
DATE: December 20th, 2009
TIME: 2:00pm ET/11am PT

More questions come into the Thomson technical support team regarding proper lubrication of mechanical motion control components than for almost any other topic. Unnecessary machine downtime and high maintenance costs are easily avoided with the right information in hand. As the inventor of the Linear Ball Bushing Bearing® and with over 60 years mechanical motion application experience, Thomson is uniquely qualified to help answer these questions.

What IS the number one lubrication mistake? What is the difference between weight and viscosity? Which lubricants best extend product life? Which are best for food grade or submerged applications? What is the best way to remove grease? This webinar will answer those questions and more. Proper lubricant selection can significantly improve performance and extend product life. This webinar will cover lubrication for Plain Bearings, Ball Screws, Ball Splines, Linear Bearings and Profile Rail.
