Cone Drive gear units, which promise improved seal arrangement, is now in control of the giant shutters that protect the Keck 1 telescope on Hawaii's Mauna Kea volcano, the world's largest optical and infrared telescope. The units come with modified input shafts, hollow shafts, housings, special output mounting flanges, and keeper plates in hollow bores. They also feature 14 custom 8-inch center distance HP double enveloping worm reducer units with a special ratio of 9.75:1.

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.
