Patent DE-2851130-A1 (DE)
Title: Electric component, esp. for appts. used to drive motor cars - where flat ceramic substrate is coated on rear surface with material causing curvature of substrate during sintering
Inventor: MUELLER KLAUS DR
IPC: H01L23/15
Filed: 1978-11-25
Abstract: The component consists of an initially flat ceramic substrate coated on one side with a material (A) which possesses a different shrinkage on sintering than the substrate, which is also coated with a thin layer of metal (A). When the coated substrate is intered, the different shrinkages of the substrate and layer (B) result in a prod. which is curved. The substrate pref. consists of partly or completely stabilised ZrO2, whereas layer (A) is pref. Al2O3; and metal (B) and/or its connections are pref. applied by printing, rolling, or spraying; or by evapn. onto the sintered substrate. Metal (B) is esp. applied as a meandering pattern on one side of the substrate whereas layer (A) is located on the other side of the substrate; and the prod. is esp. an electric heating element in control or measuring appts. in motor cars. Metal (B) can easily be applied in mass prodn. to a flat substrate, which is then curved to concentrate or disperse the heat rays produced by the prod.

Patent DE-2855750-A1 (DE)
Inventor: WIDMER MAX
IPC: B62D53/08
Filed: 1978-12-22
Abstract: The displacement device is provided with a baseplate (1) which is permanently connected to the vehicle and bears a pair (5, 5a) of toothed racks, a slide (11) which is fitted on the baseplate and receives the fifth-wheel coupling (10) and locking bolts (23, 23a) which are guided on the slide transversely with respect to the sliding direction and can be engaged in and disengaged from the tooth gaps (6) of the toothed racks by means of the force of a spring (33) and by means of a lever (26) which is connected to the said bolts (23, 23a) in an articulated fashion. The object of the invention is to provide a displacement device with a lever and locking system which can be actuated with relatively little force and with which secure engagement of both locking bolts is ensured. In order to achieve this objective, a stop (27, 27a) is attached to the slide in the region of each locking bolt, which stop (27, 27a) on the one hand limits the disengagement travel of the locking bolts and on the other hand has the purpose that, when one locking bolt rests against this stop, an axis of rotation for the pivoting movement of the lever can be formed simultaneously with the articulation axis connecting the locking bolt to the lever (26) so that the other locking bolt can be disengaged, the lever (26) being connected individually to each locking bolt (23, 23a) but being freely movable with respect to the slide (11). <IMAGE>

Patent DE-2920350-A1 (DE)
Inventor: SANDER BRUNO DIPL CHEM DR
IPC: C02F11/122
Filed: 1979-05-19
Abstract: A process for dewatering sewage sludges, the dewatering characteristics of which have been improved by adding an organic flocculant, on a chamber filter press, wherein the greater part of the water in the flocculated sludges is removed by gravity filtration in a process step upstream of the chamber filter press, without application of a pressure difference, and the actual pressure filtration, on the chamber filter press, is only then carried out. In principle, commercial products can be used as the organic flocculant. These are water-soluble, macromolecular compounds which have been obtained by polymerization or copolymerization of acrylamide, acrylic cid and/or their salts, or of esters of acrylic acid or methacrylic acid with specifically modified alcohol components.

Title: External aircraft load automatic release - has wedge-operated toggle links between body and hinging claws
Inventor: HUETTER HORST
IPC: B64D1/04
Filed: 1980-03-06
Abstract: The automatic release is for loads suspended outside aircraft, having left- and right-hand hinging claws bearing against the outside of the load and pivoting on a central body, being equipped with supporting buffers. The body accommodates the pivoting mechanism. A two-part (15,16) toggle link (14) is attached to the end of each claw (11) towards the body (10), one of the parts hinging on the body. At the coupling pin (20) between the parts one of the latter has a sideways-protruding portion (24), against which one of the ramp faces (22,23) of a wedge (21) sliding in the body bears. Movement of the wedge forces the toggle links outwards and turns the claws against the load.

Title: Data transmission station remote controlled power supply - uses clock pulse generator to monitor recognition frequency oscillator at reserve supply station
Inventor: ROTHER DIETER
IPC: H04B17/40
Filed: 1980-03-27
Abstract: The power supply system uses symmetrical lines to connect amplifier stations, using phantom circuits for a control system. Each station includes a recognition signal oscillator which is used in a fault locating system. The different signals for the different stations are monitored at a central station with a system of filters for separating the signals. When the supply to a station fails, a reserve supply can be brought into operation. When a supply fails, a clock pulse generator at the station is operated and used to monitor the recognition frequency oscillator of a reserve station. This monitored signal is then selectively applied to an indicating device at the central monitoring station.
