Title: Pneumatic centrally operated vehicle door locking mechanism - has cylinders with locking function controlled by solenoid valves operated from central switch
Inventor: REINHARD THEODOR
IPC: E05B65/38
Filed: 1976-12-30
Abstract: The centrally operated locking system on cars has pneumatic operating cylinders each with its own electrically controlled valve. The system is fitted with pneumatic cylinders carrying integrally designed switch valves controlled electromagnetically. The switch valves are connected to pneumatic control line operating with negative pressure. The door next to the driver is fitted with a change over switch operated by the door key. When locking the door, a movable contact moves from its neutral position to activate a locking circuit. The switch valve is moved into such a position as to admit vacuum into the cylinder space of the pneumatic cylinder which moves the locking mechanism into an operative position.

Title: Buffing machine pad cleaner - is apertured stand with radial curved bars for flexing pad and loosening dirty wax
Inventor: WHITTAKER RICHARD E
IPC: A47L11/40
Filed: 1977-05-16
Abstract: The floor buffing machine may be positioned and operated on a stand to remove built-up accumulations of wax and dirt from the buffing pad. The stand has a flat elevated apertured surface with radially positioned curved bars arranged in an annular pattern over the apertures. Operation of the buffing revolves the pad relative to the bars (17) and their arrangement and shape causes the buffing pad to be flexed progressively so as to effectively loosen accumulated wax and dirt deposits which otherwise interfere with the efficient use of the buffing pad. The loosened deposits fall through the openings (15) into the interior.

Title: Removal of solvent traces from effluent streams - using stream stripping of effluent with return of condensate to separator
Inventor: HAECKER WOLF DIETER DR
IPC: B01D3/38
Filed: 1979-03-08
Abstract: The effluent from a solvent recovery plant is passed through a stream stripper to remove traces of solvent. The vapours then flow into a condenser where they are condensed. The resulting mixt. of solvent and water flows down to the separator on the solvent recovery section. The stripped solvent either flows to drain or is used to generate the steam to regenerate the carbon recovery beds. For use with carbon bed solvent recovery systems. Maximises recovery and avoids the need to discharge contaminated water to drain.

Title: Layered reinforced concrete slab with lattice beams - has thin foreign layer separating basic slab and added site concrete
Inventor: HERZOG PETER
IPC: E04B5/38
Filed: 1979-03-31
Abstract: A prefab concrete slab is constructed with lattice girders for reinforcement. An additional reinforcement is laid across the main reinforcement, and site concrete is then applied. A thin layer (4) of foreign material such as cardboard, plastics foil or metal foil, is sited between the prefabricated slab (1) and site concrete layer (5). this runs laterally between the lattice girders (3), parallel to their longitudinal axis, and effectively separates the concrete layers. This simplifies computation for design, and less reinforcing steel is needed.
