Patent DE-3047772-A1 (DE)
Title: Deicing control for windscreen washer jets - with heat conducting connection to engine
Inventor: GELLER GEB GREDLER
IPC: B60S1/52
Filed: 1980-12-18
Abstract: The bonnet mounted windscreen washer jets are streamlined and covered with an insulating cover. A heat conducting strip is fitted to the jet body under the bonnet and leads to a hot part of the engine. The insulation is applied under pressure and forms a streamlined cowl to prevent wind chilling of the jet. The heat is conducted from the manifold or from the exhaust system by any suitable means and thus requires no external heat supply or complex protective system.
Patent DE-3100032-A1 (DE)
Title: Drive motor for space vehicles
Inventor: MORITZ RICHARD
IPC: B64G1/40
Filed: 1981-01-02
Abstract: The drive motor is used for accelerating and controlling space vehicles and aircraft. It consists of a mass which is moved at different speeds within an orbit. A thrust force in the direction of the maximum speed is obtained by the different centrifugal forces thus produced. The resultant force is obtained by vectorial addition of the centrifugal forces, said force producing the magnitude and direction of the thrust force. It must always be in the same direction. The following means are used, for example, to achieve different centrifugal forces:   A) a device according to Fig. 1, the mass (3) being mounted on a gearwheel (1), on the half (1.1). The motor (4) rotates at a higher speed in the region (1.1) than in the region (1.2); B) a device according to Fig. 2, the mass being located on the rotor (6).   The poles (5) must be driven continuously at different excitation times, for example becoming smaller from P1 to P7 and becoming larger from P7 to P12. The force direction (resultant 7) is located over the pole P7 (maximum speed). The motor is constructed in pairs in order to compensate for lateral forces. <IMAGE>

Title: Heating system for closed rooms
Inventor: BOLLINGER VIKTOR
IPC: F24D13/00
Filed: 1981-04-15
Abstract: The heating system intended for closed rooms serves for the better heat distribution of the heat generated by conventional convection heating systems. To this end, the heating system has a number of thermoelectric heat radiators which work as a heat pump according to the Peltier effect and which are installed under the ceiling and if appropriate also on the walls of the heated room and if appropriate can be aligned in such a manner that they radiate heat extracted from the room air flowing through selectively into given regions of the heated room. Thus, the average room temperature necessary for adequate heating can be lowered which leads to heating cost savings.

Patent DE-3118381-A1 (DE)
Inventor: ROTHE ANSELM DR RER NAT
IPC: G01N33/52
Filed: 1981-05-09
Abstract: A test strip for analyzing a liquid sample has a carrier or handle, a slowly-absorbent layer fixed thereupon which slowly sucks up the liquid sample, a liquid impermeable layer fixer thereover, an absorbent reagent layer fixed thereover, and a mesh covering these, which mesh layer is fixed next to the slowly-absorbent layer on to the carrier. The mesh and layer portions of the test strip can thus be briefly immersed in the liquid sample with the carrier and withdrawn for observing the analyzing reaction of the reagent and liquid sample absorbed into the absorbent reagent layer through the mesh, the mesh serving to conduct excess liquid sample from the adjacent surface of the absorbent reagent layer to the still absorbent slowly-absorbent layer so that the excess liquid sample does not interfere with the observation of the reaction.

Title: Method for filling and emptying housings for gas-insulated electrical apparatuses and installations
Inventor: BESSEI HERBERT DR ING
IPC: F17C5/06
Filed: 1981-06-10
Abstract: The subject-matter of the invention is a method for filling and/or emptying housings for gas-insulated electrical apparatuses and installations, in accordance with the so-called displacement method. The aim is to recover economically as high a proportion of the insulating gas as possible from the gas mixture displaced out of the housing. For this purpose, the displaced gas mixture is compressed and is fed to a cooled separating container. The latter has a gas outlet valve at its highest point and a controllable flow outlet valve at its lowest point. The valves are operated automatically in accordance with predetermined operating conditions (pressure, temperature and fluid level) in the separating container.

The excavating tools can be arranged on one-piece or multi-piece swivel arms (14, 50) or are guided on working platforms (62, 63, 64) which are arranged at a distance one above the other. <IMAGE>
Patent DE-3128725-A1 (DE)
Title: Fitting for doors or windows
IPC: E05B15/02
Filed: 1981-07-21
Abstract: The fitting, shown in Figure 1, in the form of a plate consists of an outer cover cap (1), of a protective cap (2) produced from high-strength metal, of an insertion plate (3) made of ceramic, of a plurality of bolts (4) equipped with an internal thread and of a handle (5). The insertion plate (3) made of ceramic as well as the cover cap (1) and protective cap (2) contain an orifice for a lock cylinder. Drilling into the tumblers of a lock cylinder is reliably prevented by the ceramic insertion plate, since this, although sometimes springing apart under attempts at drilling in, nevertheless cannot be drilled through, since the individual components of the sprung-apart insertion plate cannot escape from inside the fitting. <IMAGE>

Title: Power-feeding circuit in a telephone set
Inventor: REUSS MANFRED ING GRAD
IPC: H04M19/08
Filed: 1982-10-22
Abstract: A power-feeding circuit for feeding a microphone and a loudspeaker amplifier in a telephone set has a polarity reversal protection circuit which can be inserted into the voice circuit of the telephone set and outputs at its output a polarity-independent power-feeding voltage to the loudspeaker amplifier. In parallel with the loudspeaker amplifier, a microphone branch, which contains the microphone and a transistor in series, is also located at the output of the polarity reversal protection circuit, the microphone being connected to the collector of the transistor. To achieve a constant power-feeding voltage and, in particular, to reduce a reaction of the loudspeaker amplifier to the microphone impedance and, at the same time, permit the most varied microphone types to be used in the power-feeding circuit, a control loop is provided which contains the base-emitter path of the transistor and corrects the power-feeding voltage to a predetermined value with decreasing or increasing direct-current resistance of the loudspeaker amplifier and, at the same time, shifts the operating point of the transistor of the microphone branch in the cutting-off or turning-on direction, respectively.

Title: Push-button switch group
Inventor: BOETZ JAKOB
IPC: H01H13/56
Filed: 1982-11-03
Abstract: In a push-button switch group consisting of at least two push-button switches having a housing 10 and in each case one push button 15, 15' on which a spring elements acts and which is held in a switched-on position with the aid of a control cam 24, 25 and a control lock 21 running in the control cam, and, when the other push button in each case is switched on, can be released from its switched-on position, it is intended to prevent it being possible to push the second push button down when the first is blocked in its switched-on position by means of an external force. As can be seen from Fig. 1, this is achieved in that the means 40 which are used for alternately releasing the push buttons 15 and 15', can be moved out during the switching-on movement of a push button over the position which they occupy in the release position of the one control part 21, and in that this movement can be blocked by a stop which can move vertically with the other push button. The stop is preferably formed by the control part 21, which can be displaced vertically. <IMAGE>
