Title: Electrical contact plates for metallurgical applications - has two part foot for coolant channel with central pillar and bolts
IPC: H05B3/03
Filed: 1979-04-23
Abstract: Each contact plate is provided with cooling channels for use in high electric current circuits for metallurgical treatment. The foot of the plate is in two parts. The channel is defined between them overcoming the problems associated with providing such a channel in one piece plates. The channel which may be comparatively complex compared to that in a one piece plate is formed in the lower surface of the upper of the two parts. This also carries the contact pillar and coolant, normally water, entry and exit points and the contact area on its upper surface. The lower and thinner of the two parts has a plain surface and closes off the open side of the channel and is soldered to the upper. Bolts between the two ensure correct location and prevent accidental separation.

Patent FR-2464727-A1 (FR)
Inventor: BEYL JEAN JOSEPH ALFRED
IPC: A63C9/08
Filed: 1979-09-14
Abstract: Under normal skiing conditions, two lateral arms of a jaw unit cooperate with the toe end of a ski boot in order to maintain the boot in the axis of the ski and are held in position with a force designated as the inherent stiffness of release. When an excessive twisting effort is exerted on the skier's leg, the arms both move in a transverse direction with respect to the ski in order to permit lateral disengagement of the boot. A toe abutment feeler member is in contact with the front end of the boot and cooperates with a spring-loaded piston unit in order to reduce the inherent stiffness of release as well as resistance to torsional disengagement in the event of a forward fall of the skier and/or of an axial thrust exerted by the boot, thus achieving considerably enhanced safety.

Title: Dual circuit pressure medium brake valve - has setting piston with double membrane sealing element for non-linear characteristic adjustment
IPC: B60T8/26
Filed: 1980-01-11
Abstract: The pressure ratio maintaining valve has a double seated valve to regulate the differential pressure to the front and rear wheel brakes. A control piston is linked to the valve housing by a double membrane sealing element so that the relative effect of the valve changes with piston deflection, which causes support members to change the respective membrane surface. The non-linear brake modulation characteristic provides enhanced brake effect at higher front axle loadings, esp. during heavy braking. The displacement of the floating piston changes the effective area of the membranes to alter the modulation effect.
