Title: Open-end spinning rotor roller bearing - has an intermediate ring with auxiliary drive to give a differential assembly
Inventor: STAHLECKER FRITZ
IPC: F16C19/55
Filed: 1976-06-04
Abstract: The roller bearings for the spinning rotors of open-end spinning units ride in a race formed by an outer and an inner ring. An intermediate ring is placed between the rollers on the inner ring or axis and the rollers on the outer ring. This acts as the inner race path for the outer rollers and as the outer race path for the inner rollers. An auxiliary drive gives the intermediate ring the same rotary direction as the other rotating components, the outer ring or the inner ring/axis. The design gives a differential roller bearing where the total rotary speed is divided into stages so that no section of the roller bearing assembly carries the full load.
Patent DE-2629042-A1 (DE)
Title: Harrow with outer section which swing upwards hydraulically - has closed end of hydraulic cylinder connected to hydraulic reservoir(OE150476)
Inventor: PRILLINGER ERWIN DIPL ING
IPC: A01B73/04
Filed: 1976-06-29
Abstract: The harrow's two outer sections are swung upwards by a hydraulic piston-and-cylinder (7), which connects their frames; they swing downwards under gravity. When they were held in the down position mechanically, inadvertent operation of the hydraulics before the bolts were withdrawn could strain the frames. To avoid having to strengthen the frames, the "closed" end (9) of the hydraulic cylinder is connected to a hydraulic reservoir (10), open to the air. When a valve (12) in the connecting pipe is closed, the piston is locked against further movement. This locks the frames in position. If the hydraulic pressure is now applied before the valve is opened, the force is confined to the hydraulic system - which must on other grounds be made strong enough to withstand it - and cannot strain the frames.
