Title: Hydraulic control of automobile gear box - has valves actuated by pressures proportional to engine torque and speed
IPC: F16H63/30
Filed: 1976-03-05
Abstract: The hydraulic control of an automobile gear box utilises a pump which supplies oil to a slide valve. In addition, a pressure regulator controls the pressure to a value P which is proportional to the engine torque and a value P2 proportional to engine speed. Three receptors control the three forward speeds. Two receptors are supplied continuously with oil at pressure P2. The position of the slide valve determines which receptor is supplied with a pressure P3 which is also proportional to engine torque. Thus the speed selected is a function of engine torque.

Title: Hollow metal toy ball mfr. - includes welding hemispheres with surface patterns and edges rectified after welding
IPC: B21D51/08
Filed: 1976-12-21
Abstract: The process for fabricating hollow metal balls for games, forms two demi-spheres (1b) which are welded together, but forms surface patterns during a preliminary phase, and prepares the edges of the demi-spheres in the formative phase. The process includes pressing or rolling a surface pattern onto a metal sheet. Circular plates are press cut and formed into demi-spheres. Their edges are rectified and calibrated then welded together. Finally the ball is coated with plastics or other material. The pre-welding plases are carried out on a multipost machine, and the edge calibration and finishing may be carried out by punches on the sphere-forming punch. Complex surface patterns may be obtained by multi-stage initial pressing or rolling.
