Title: Pressure cooker with built-in safety mechanism - prevents lid being removed instantly before residual pressure is released
Inventor: TANNER WILLY
IPC: A47J27/092
Filed: 1975-05-07
Abstract: The pressure cooker has a manually operated stop mechanism which can be provided in the lid handle and is triggered on closing the lidso that on rotation when opening the lid, the latter is detachably held by the stop mechanism in a position where it cannot be removed from the cooker pot but a communication port is set between the inside and ouside of the cooker. Any remaining pressure inside the cooker can escape without danger and the lid can therefore not be removed too quickly, but a conscious manual step has to be carried out. The stop mechanism can be a spring-operated locking pin in the lid handle which engage with a catch on the handle of the cooker pot.

Title: Fluid damping for periscope bearings - has viscosity variation compensation and additional friction cylinder linings
Inventor: ABEL ALFRED
IPC: F16F9/52
Filed: 1975-05-15
Abstract: The fluid damper system has temperature increase compensation and is incorporated in a periscope bearing damper. The temperature compensation (due to viscosity changes) is achieved by variation in the size of a constriction in the shock absorber, in order to produce as near as possible constant damping. The periscope (1) housing has two bearings (4, 5) inside a bearing bush (6), the lower wall (8) of which is bolted (9) to the housing (2). The upper wall has inner flanges (10), and the enclosed chamber (12) is partly fluid-filled (13). A disc (7) supports an end seal (11). A hole (14) is drilled in the lower end (8) with a flexible connector tube leading to a fluid reservoir (18) kept at the same temperature as the housing by good thermal contact. Additional friction sleeves (20, 21) increase friction damping, and are attached to either the periscope or bearing box.

Title: Crucibleless zone melting of semiconductor crystal rod - uses funnel sleeve around pinched zone for direct current passage contact
Inventor: KELLER WOLFGANG DR
IPC: C30B13/18
Filed: 1975-07-11
Abstract: The parent patent describes a crucible-less zone melting process for single-crystal growth wherein a funnel-shaped sleeve surrounds the conical zone of the semiconductor crystal rod above the seed crystal to support it with its metallic filling and prevent vibrations. In this addn., this sleeve serves also as the bottom contact for a current which is passed through the rod; the top contact is a metal sleeve which is fitted with an insulation in the top holder of the rod and is in direct contact with the stock. This changes the heat balance in the fursion zone by the produced PELTIER effect an enables the growth process to be controlled by current pulses. The current density can be much higher than when the current must pass through the pinched rod zone.

Title: Supports for high speed rail vehicle - uses liq. oxygen to produce ice coating on friction support pads contacting rails
Inventor: DRITTENPREIS HERBERT
IPC: B61B13/08
Filed: 1976-01-30
Abstract: The low-friction ultra-high-speed passenger transport system can be used on railway lines a conventional design, achieving speeds of 300 to 450 Km/h. The passenger compartment cell units is set up with its centre of gravity very close to the track.
