Magnets let this cable carrier float within its track
You may be tempted to lump all cable carriers together because their differences tend to be subtle ones related to the geometry of their links and their use of wear-resistant materials. At the fair, though, Igus GmbH demonstrated a carrier with a high-tech twist that was hard to miss. The company debuted a "magnetic energy chain" that floats within its own track.
To turn an ordinary energy chain into a maglev system, Igus installed magnetic modules on both sides of a fixed track and embedded pieces of iron in the plastic links of the chain itself. The result: a reduced-contact cable carrier that moves quickly with lower forces, less wear and reduced noise. The lower half can optionally be fitted with magnetic modules too, opening up the possibility of a chain with still greater wear resistance and whose top and bottom halves can move independently. According to Frank Blase, the company's chief executive officer, the magnetic system can move at speeds up to 15 m/sec, carrying loads of up to 4 kg/m of chain. A chain with 40m of travel, the maximum for this system, can accelerate as quickly as 90 m/s2, Blase adds. "That's impossible with any other carrier system today."
What makes this movie stand out from the typical high school sports story is that the teenagers are undocumented immigrants, and the big game is a NASA-sponsored marine robotics competition. Like many other Hollywood movies, however, Spare Parts only tells part of the story. What the film shows -- and doesn’t show -- raises important issues affecting STEM education in the US.
Instead of sifting through huge amounts of technical data looking for answers to assembly problems, engineers can now benefit from 3M's new initiative -- 3M Assembly Solutions. The company has organized its wealth of adhesive and tape solutions into six typical application areas, making it easier to find the best products to solve their real-world assembly and bonding problems.
Load dump occurs when a discharged battery is disconnected while the alternator is generating current and other loads remain on the alternator circuit. If left alone, the electrical spikes and transients will be transmitted along the power line, leading to malfunctions in individual electronics/sensors or permanent damage to the vehicle’s electronic system. Bottom line: An uncontrolled load dump threatens the overall safety and reliability of the vehicle.
