Title: Heater for car door - has double heat pipe transfer system with contact area alongside door hinge
Inventor: ANDRES RUDOLF
IPC: F28D15/04
Filed: 1980-01-30
Abstract: The heater for a car has a booster comprising heated panels in the doors linked to the engine by heat pipes. At least two sets of heat pipes are required, linked near the door hinge by opening contacts so that rigid pipes can be used. The contact areas comprise a fixed area (11) linked to the engine and a moving area (12) attached to the door. The fixed area has some elasticity using a bellows construction with an integral gas cushion. This ensures max. thermal contact and heat transfer. No moving parts are required for the heating panels, nor any pumped fluid curcuit.

Patent DE-3023976-A1 (DE)
Title: Air or steam feed appts. for concrete pan mixer - has feed element with hard rubber corner piece esp. wedge with self closing outlets
Inventor: BURKARD RUDOLF
IPC: B28C5/46
Filed: 1980-06-26
Abstract: Appts. has a feed element which leads into a pan, located in the corners between the pan base and the vertical inner or outer wall, or in the discharge slide or on the wall of the pan. Each feed element is of elastic, hard-wearing material having an internal cavity; the steam, air, etc. is fed into this cavity and escapes from it through a release gap or bores under the applied pressure to enter the internal chamber of the mixer. The closure pressure causing the lips of the gap or the bores to close is provided by the in-built stresses in the feed element and/or in-built closure springs. In the case of an annular pan-type concrete mixer the feed elements may consist of components screwed to the outer wall and/or the base and constituting corner profiles. These tend to prevent accumulation of concrete in the corner and their elasticity makes them self-cleaning. With this arrangement, the height and the horizontal width of the corner elements is pref. 4-7 cm and flat springs are pref. used. The difficulties associated with valves, etc. are eliminated. The forming of a concrete crust in the corner is considerably reduced or eliminated. Wear on the blades of the mixer is reduced.

Title: Gyratory centrifuge
Inventor: HULTSCH GUENTHER
IPC: B04B7/16
Filed: 1981-12-23
Abstract: In the processing of certain solids in gyratory centrifuges, the angle of adhesion which, by being exceeded, is known to be utilised to transport the solid on the inner surface of the screening drum depends on the degree of dehumidification of the solid. As a result, disadvantages arise in the customary screening drums with a uniform approach angle due to the excessively rapid transport of the solid at the open screening drum end. According to the invention, the approach angle is matched to the desired transport conditions at the open end of the screening drum and the transport in the rest of the screening drum area is brought about by a baffle which is attached to the hollow shaft and thus carries out a movement relative to the screening drum.
