Patent DE-4039377-A1 (DE)
Inventor: BAITZ GUENTER DIPL ING
IPC: G01G21/22
Filed: 1990-12-10
Abstract: A weighing device for self-service of goods in department stores has a dormant scale (2) arranged in an upwardly open, floor-mounted enclosure (3). The dormant scale (2) has a device (8) for hanging at least one removable carrying container (11). The dormant scale is protected against possible outer influences by the floor-mounted enclosure (3), so that delays are avoided during the weighing process. The arrangement of the carrying container (11) on the dormant scale (2) allows buyers to leave the weighing area more quickly with the weighed goods. A shopping container, for example a shopping trolley (21), may also be used as a weighing receptacle for the scale in the floor-mounted enclosure (3). For that purpose, the dormant scale (50, 60) is designed with a U-shape when viewed from above and is provided with support elements (52, 71) for the shopping container.

IPC: B26D7/08
Filed: 1991-01-08
Abstract: Cutting an outline in textile material which may be woven, knitted or non-woven natural or synthetic fibre.

Title: Fluid distributor baffles for mass and/or heat exchangers - comprising meshed basins incorporating capillary tubes. - by introducing water contg. ammonium, and air, then mixed with fresh ammonia
Inventor: GRABBERT GERT DR
IPC: B01D3/22
Filed: 1991-01-25
Abstract: In the treatment of gas effluent from fossil fuel power station, a sulphur-bearing fuel is burned. The gases pass through a nitrogen extractor reaction unit downstream of which there is a heat exchanger from which ammonium salts are removed by water. The water effluent is passed to a column into which air is introduced. The effluent air and desorbed ammonia it contains is then mixed with the fresh ammonia produced by the nitrogen extractor. The water flowing into the column receives an addn. of alkali resulting in a deposit which can be removed by sedimentation or filtration. The process gas used is either rareified air or cleaned gas effluent. USE/ADVANTAGE - Water effluent from the power station is of a quality which may be released.

Title: Solenoid check valve for vehicular antilock braking system - incorporates twonon-return ball valves closed and opened by different levels of solenoidcurrent
Inventor: HONG YEH-SUN
IPC: B60T8/36
Filed: 1991-01-30
Abstract: In a three-port three-position valve, two pressure pistons (14,15) are driven outwards by helical springs (e.g. 15b) leaving a narrow air gap (G1) and a wider gap (G2) on either side of a central yoke (12). One piston (14) lifts a non-return ball valve (16a) from its seating until weak current through the solenoid (11) retracts the piston (14) and closes the narrow gap (G1). Another ball valve (17a) remains seated (12b) until the other piston (15) is retracted by stronger current. ADVANTAGE - Escape of oil is avoided and rapid and precise reversals of pistons are ensured at opening and closure.

Title: Joining ends of feed belt for sander - by removing lengths of belt layers to form stepped space when ends butt together, fitting corresp. glued piece into space and hot pressing
Inventor: BRAEUTIGAM JUERGEN DIPL ING
IPC: B24D11/06
Filed: 1991-02-02
Abstract: A process joins together the ends of a feed belt for a belt sander machine, where the upper side of the belt made of elastomer conveys the workpiece and is bonded to an embedded textile reinforcing layer; the underside of the belt is a low friction fabric which is bonded to the textile reinforcement by a layer of rubber. In the process the ends are prepared, laid together with at least one infill between, and the assembly is cured or stuck together. An adequate length of the low friction underside is removed from each end of the belt, and the two ends are butted together; where the low friction layer and rubber bonding layer have been removed from the join area the space left is filled with a piece of low friction material plus bonding rubber and a bridging piece of fabric, the total thickness of the rubber and fabric being about that of the rubber in the original belt; the infill is then cured or stuck in situ. ADVANTAGE - The process makes the joint with properties virtually identical to those elsewhere in the belt. It minimises waste of material.
