Dana Corp.'s Driveshaft Div. has introduced a magnetic-pulse welding process for joining ferrous and non-ferrous material to form lighter, more compact--and in some cases--previously non-producible driveshaft configurations. "The process results in a metallurgical attachment that outperforms conventional MIG welding and competing mechanical attachment processes," says Jim Duggan, Dana's chief engineer of advanced design. The process creates an intense magnetic field by downloading large amounts of electrical energy into a specifically designed coil over a very short period of time. When an aluminum tube, for example, is subjected to the field, it collapses inward with sufficient force to weld itself onto a stationary component, such as a steel or aluminum shaft. The solid-state weld process requires no heat, with the component orientation controlled by machine tooling. FAX (419) 866-2616.
Some of our culture's most enduring robots appeared in the 80s. The Aliens series produced another evil android, and we saw light robot fare in the form of Short Circuit. Two of the great robots of all time also showed up: The Terminator and RoboCop.
Major global metropolitan areas are implementing a vast number of technology, energy, transportation, and Internet projects to make the metropolis a friendlier, greener, safer, and more sustainable place to be.
Here’s a look at robots depicted in movies and on TV during the 1950s and 1960s. We tried to collect the classics here, omitting the scores of forgettable B movies such as Santa Claus Conquers the Martians and Dr. Goldfoot and the Bikini Machine. Stay tuned for slideshows of robot stars from later decades.
