Abstract: A ring dispenser comprising a rotating rod having an acme thread along one portion thereof and a helical coil spring at a dispensing end thereof feeds individual rings to a ring transfer device located at the dispensing end of the rod. The rod is rotated by a motor and the rings are automatically separated and directed to the end of the rod where a sensor detects the presence of the ring and stops the motor. When the ring transfer device is ready to pick up a ring, the motor starts again and a ring slides off a conical tip of the rod onto the transfer device by rotation of the rod. The rings have diameters greater than the separation between the individual threads of the rod so that the rings move on the crests of the threads and are out of engagement with the thread roots. The spacings between the convolutions of the coil spring are greater than the thickness of the rings so that the rings move on the rod surface as the rings approach the dispensing end of the rod.

Abstract: A conveyor of the type having a flexible endless belt with generally horizontal top and lower return levels is movably supported for delivering materials between load and unload stations. A plurality of transversely spaced pairs of wheeled trolleys or other types of slide mechanisms are movably mounted on spaced horizontal guide rails and are attached to opposite sides of the conveyor belt by brackets and small sections of flexible belt material. Each of the trolleys has a pair of horizontally mounted wheels and a pair of vertically mounted wheels which move with the conveyor belt along the guide rails to maintain accurate guidance and tracking of the conveyor belt. One of the trolleys of each pair is spring biased to compensate for possible variations in the guide rails.

Abstract: This invention serves to cool the lubricant used by a mechanical constant speed drive (CSD) driving an aircraft alternator which aircraft is powered by a turbofan engine. The system cooling capacity is supplemented by an existing engine fuel/oil heat exchanger thereby effectuating a reduction in size of the CSD fan air/oil heat exchanger and minimizing an aircraft engine performance penalty.
