A magnetic coupling assembly for selectively rotating rollers of a roller conveyor when the torque required to maintain this rotation does not exceed a predetermined threshold is described herein. The magnetic coupling is mounted to the side rail of a conveyor, below the conveyor rollers and include a driving portion rotatably mounted to the side rail and a driven portion rotatably mounted to the driving portion. Corresponding friction surfaces of the driving and driven portion are brought and maintained in contact via a magnet and an element made of magnetic material or another magnet. Means for varying the distance between the magnet and the element made of magnetic material are disclosed. The present invention is also concerned with means for simultaneously adjusting more than one coupling assembly and with means for detecting the rotation of conveyor rollers.

Magnetic coupling assembly for conveyor rollers

A compact mechanical lock for bi-parting handles of passenger doors used on mass transit vehicles. Rotating lock cams cooperating with an interlocking lock plate to ensure proper closure of each panel prior to lock actuation.

Compact panel lock for an overhead mounted door panel operator

A power door operator for vehicles requiring uninterrupted car surfaces in a door area and minimal use of car interior space, particularly in the closed position. The equipment provided utilizes a rotary motor drive and distributed gear system for moving opposing door panels away from an opening in the car wall. Movement of the doors into and out of the car door opening is accomplished through use of controlled reaction travel of the rotary drive motor.
