Title: Torque limitation fluid coupling - has annular weir returning fluid direct to reserve chamber from turbine working area
IPC: F16D33/08
Filed: 1976-03-11
Abstract: The coupling delays the acceleration to full speed of machines with high inertia, being particularly for use between a squirrel-cage motor and a centrifuge. An annular weir (4) connects the working area of the turbine wheel (2) and the reserve chamber (3) accommodating the spare fluid. This collects the slip flow fluid and returns it direct to the chamber. The portion of the turbine wheel working area, in which there are no blades, can be used as the reserve chamber. The design is simple and cheap to produce, and provides a self-regulating effect. A long working life is achieved whilst operating under conditions of maximum efficiency.

Title: Side-feeder for self-loading trailer - has motorised roller conveyor with end stop to control loading of bales in groups
IPC: A01D90/08
Filed: 1977-01-14
Abstract: Bales of forage are fed by an elevator loaded and placed on the track which is used for loading and unloading. The track incorporates a motorised roller conveyor. Engagement of an end stop on the track by a bale iniates a loading cycle on to the platform of the trailer when three bales are in position on the track. The first bale on the track is braked by a deflector until three bales are on the track. When this condition holds, the first bale can pass to the end stop so causing the three bales to be discharged on to the trailer. The deflector is raised clear to permit unloading of the bales from the trailer, the travel of the bales being always in the same direction along the track.
