Title: Hydraulic transmission with variable speed reduction - uses two identical machines as pump and motor, each with variable eccentricity rotor for sliding vanes
IPC: F16H43/00
Filed: 1976-03-05
Abstract: A hydraulic transmission system uses two identical machines. One machine operates as a pump and supplies fluid at pressure to the second machine which operates as a motor. Each machine consists of a cylindrical casing with end cover plates. A rotor of variable eccentricity runs in bearings mounted in the cover plate. The rotor has three sliding vanes (5,6,7) which are kept in contact with the bore of the casing by a central shaft. By varying the eccentricity of the rotor, the volume of fluid flowing through the machine per revolution can be controlled. The ratio of speed reduction between the pump and the motor is thus a function of the eccentricities of the rotors of both machines.

Title: Continuous annealing plant - with carriage motors in strip looping towers controlled with feedback from strip tensionmeter
IPC: B21C49/00
Filed: 1976-08-23
Abstract: Continuous annealing line for cold-rolled steel strip consists of a heating, equalizing, quenching, over ageing and cooling zone.

Title: Isostatic compaction vessel housing two liquids - constituting primary and secondary pressurisation agents separated by flexible diaphragm (SW 16.5.77)
IPC: B22F3/04
Filed: 1977-01-11
Abstract: Isostatic compaction appts. for pulverulent material comprises a pressure vessel which contains two liquids separated by a flexible partition. The material is housed in a container which is supported in a deformable container in the vessel. The deformable container is in contact with one liquid which may be pressurised, via the flexible partition, by the other liquid which constitutes the primary pressurisation agent.
