Title: Power assisted steering arrangement for motor vehicle - has control ascertaining assisted steering angle from working neutral position value
Inventor: SHIRAISHI YASUHIRO
IPC: B62D7/15
Filed: 1990-04-23
Abstract: A shutter aperture (4a), a light source (5) and a photosensor (7) determine the neutral position of the steering wheel (1) and deliver a corresp. signal (N).

Title: Hydraulic system for control of press RAM - provides fast approach with high forming load by use of nested cylinders controlled by multiway proportional valve
Inventor: WALTER HEINZ ING GRAD
IPC: B30B15/16
Filed: 1990-11-16
Abstract: The upward stroking press ram is the piston (14) of a differential cylinder (11) having working chambers (16) and (17). Inside a central blind bore of the piston is a plunger (19) fastened to the bottom cover of the cylinder (11); this constitutes in effect an integral second cylinder with a third working chamber (21) at the upper end. The admission of hydraulic oil to the three working chambers is controlled by a 4/5 proportional control valve (24) whose spool position is determined by an electronic controller (34). Transducers (56) and (33) provide feedback signals of ram position and system pressure. Para movement of the spool of valve (24) in response to the controller provides both proportional and directional control, enabling a complex programme of ram travel, velocity and pressure to be produced. Rapid approach is achieved by admitting oil to chamber (21) above the plungers. To produce a high forming pressure at the end of rapid approach pressurised oil is switched to chamber (16), so that the combined effort of the integral cylinders becomes available. USE/ADVANTAGE - Can be applied to various types of hydraulic press. Simple hydraulic circuit involving relatively few components.
