Title: Device for reducing temporary pressure peaks in hydraulic systems
Inventor: HESS PAUL
IPC: F16L55/05
Filed: 1981-11-19
Abstract: In a device for reducing temporary pressure peaks in hydraulic systems, a dampened piston is combined with a sensitive diaphragm in such a way that the inert piston reacts to slow pressure and pressure-flow changes and lets them pass unimpeded, whereas the sensitive diaphragm reacts to temporary pressure peaks and either brakes the throughflow for the duration of temporary pressure peaks (series circuit) or lets the extra volume occurring due to the pressure peak flow off into a bypass line (parallel circuit).

Patent DE-3201351-A1 (DE)
Title: Rolling chain with a studded belt
Inventor: STEUER WILLI DIPL ING
IPC: F16H1/28
Filed: 1982-01-16
Abstract: Endless, elastically deformable drive chain under radial stress, comprising radially inward-tapering hollow links (1) which are arranged in series on a prestressed endless studded belt (2), surrounding the latter and secured on the latter in such a way that they are held and centred relative to one another whatever the curvature of the chain. The rolling chain can operate in tension and in compression, the chain links (1) rolling on one another in operation and transmitting the compressive forces while the belt (2) accepts the tensile forces. The inward deformability of the chain is limited by the coming into contact of the feet of the chain links in "U". Here, in the tightest deflection, the chain becomes a rigid structure and can accept a force (P) acting on it radially from the outside. The rolling chains can be used as elastically deformable planets in planetary mechanisms according to P 3114154.4 or as general driving elements where compressive or compressive and tensile forces are to be transmitted elastically. Alternatively, the chain assumes the function of a gear ring. Wear is low since the chain links roll on one another. <IMAGE>

Title: Display device for characters or images composed of individual elements on a carrier
Inventor: SCHLEISIEK KLAUS-PETER DIPL IN
IPC: G09F9/37
Filed: 1982-04-22
Abstract: In a display device for characters or images whose representation is composed of individual elements, the picture elements consist of individual subareas of the carrier with equally two-colour movable magnet or electret plates which adhere by their own force without attachment in one of two possible positions to the carrier in such a way that the entire picture element shows one of the two colours. The colour change of the element by folding back the plate can be performed electrostatically, magnetically or pneumatically. Special arrangements of the elements and their excitation systems are specified for packing the picture elements free of gaps and without mutual reaction. Electrostatic picture elements can be produced in a very small size and for low voltages. Energy and control signals are required only to change the image.

Title: Arrangement for the protection of gas-insulated, encapsulated switching installations
Inventor: PLESSL ANDREAS DR
IPC: H02B13/065
Filed: 1982-04-30
Abstract: In interrupter switching operations in gas-insulated encapsulated high-voltage switching installations (GIS) radio-frequency voltage travelling waves occur in parts (K) of the switching installation (GIS), as a result of arc ignition, which cause critical transient excess voltages. By fitting thin, poorly conductive coatings (B) having high magnetic permeability ( mu @) onto the surfaces (I, A) which guide the voltage travelling waves in the switching installation, it is possible significantly to reduce the amplitude of the transient excess voltages. <IMAGE>

Patent DE-3233277-A1 (DE)
Title: Electrooptical speed indicator according to the correlation principle
Inventor: MEYR HEINRICH PROF DR
IPC: G01P3/80
Filed: 1982-09-08
Abstract: The speed indicator is constructed for detecting the range of low speeds and high accelerations which is scarcely accessible to the known correlation-type speed indicators. A sensing head (15) having two signal pick-ups (16, 17) scans a surface (11) and a correlator (20) forms in each case one measured value (Vn) for the current speed from the scanning signals (a(t), b(t)) in short predetermined measuring periods ( tau ). At the same time, a prediction unit (30) forms a predicted value (Vn) for the probable speed from preceding values. A comparator (32) compares the measured (Vn) and predicted values (Vn) with one another. If their mutual deviation is smaller than a predetermined reference value ( delta n), the measured value (Vn) contributes to the next predicted value (Vn+1). If, in contrast, the deviation is greater, the measured value is considered to be incorrect and does not contribute to the next predicted value. At the same time, an input unit (45) increases the next reference value ( delta n+1). <IMAGE>

Title: Process for manufacturing a template
Inventor: NORDMEIER MANFRED
IPC: B05C17/06
Filed: 1982-09-14
Abstract: Templates which have, in particular small and/or narrow recesses and which have previously been manufactured as relatively expensive plastic injection moulded components due to the difficulty in removing the material to be punched out can be manufactured substantially more simply and cheaply according to the method proposed according to the invention, in accordance with which method a sheet consisting of a resistant paper material or a similar plastic film is applied to a self-adhesive sheet and in a punching device punched, together with the self-adhesive sheet remaining under it, along the contours of the template cutouts with the sole exception of the surface of the self-adhesive sheet and is pulled off in order to form the template from this self-adhesive sheet whilst leaving behind the punched-out parts remaining stuck to the latter. In advantageous embodiments of the invention, even entire sets of associated templates can be punched continuously according to this method and collected together to form packets which are only opened when used and are assembled to form the templates.

Title: Protection circuit for electrical systems and apparatuses
IPC: H01H85/46
Filed: 1982-11-08
Abstract: A protection circuit which is intended for electrical systems and apparatuses, for example hifi apparatuses, has a primary and a secondary circuit which are coupled to one another via a protection component. The protection component contains a primary element which is constructed as a melting fuse element and is connected in the primary circuit, and a secondary element which is constructed as a temperature-dependent resistor, preferably as an NTC resistor, and is connected in the secondary circuit. The coupling comprises the primary element being coupled to the secondary element thermally in a defined manner but being electrically and galvanically isolated therefrom. To this end, the primary and the secondary elements are arranged on a thermally conductive support of insulating material. Such a protection circuit ensures short-circuit protection, by means of the primary element, for the electronic components located in the primary circuit and a control or regulating task is carried out, as required in the secondary circuit, via the thermal coupling of the protection component as a function of the thermal load of the secondary element, triggered by a corresponding current load in the primary element.
