Patent DE-3521027-A1 (DE)
Title: Electrically heated or solar-heated cooker with heat accumulator
Inventor: MUELLER WALTER
IPC: F24S90/00
Filed: 1985-06-12
Abstract: An accumulator container is filled with a liquid heat transfer medium (thermal oil). Arranged in the centre on the accumulator container is an expansion space, in which cone valves with regulating levers are arranged. Around the expansion space, cooking plates are embedded in the insulation on the accumulator container. From the cooking plates, down pipes lead outside the accumulator container in the insulation to the ground. For the cooking process, the cone valve is opened with the regulating lever. The heat transfer medium flows through the cooking plate and cools down, after which it flows by convection in the down pipe to the bottom of the accumulator container. The circuit for the circulation is thus closed. The accumulator container is equipped with connection pipes for heating by solar collectors and with at least one electric resistance heater for electric heating. The cooker is universal and can also be heated by small wind and water power installations. Its use is therefore possible in many regions.

Patent DE-3528259-A1 (DE)
Title: Method and device for interferometric length measurement using semiconductor lasers as light source
Inventor: FERCHER ADOLF FRIEDRICH PROF D
IPC: G01B9/02
Filed: 1985-08-07
Abstract: This invention relates to methods and arrangements for absolute interferometric measurement of lengths by means of semiconductor lasers. For this purpose, the wavelength of the semiconductor laser 1 is modulated beyond a mode discontinuity, and the interferogram phases at the mode discontinuity are determined from the time variation of the interference term at the interferometer output 10, thus implementing a sensitive two-wavelength measurement. The combination of this method with an interferometric coarse measurement, which is likewise derived from the time variation of the interference term, leads to an interferometric length measuring method which permits the measuring of distance x, whose origin of co-ordinates is the position 13 of the reference mirror 8 mirrored at the beam splitter 5, by means of interferometric resolution. 9 is the interferometer mirror, serving as measuring probe, of the measuring interferometer. Fluctuations and drifting of the laser wavelength are compensated by a calibration interferometer having the divided surface 19 and a fixed path difference. Processing of the photosignals of the two interferometers is performed in the measuring and computing unit 11. <IMAGE>

Title: Method and circuit arrangement for automatic assembly of printed circuit boards with integrated components
Inventor: SIEGEL WERNER
IPC: H05K3/30
Filed: 1985-08-08
Abstract: The invention concerns a method and device for automated assembly of printed-circuit boards with integrated components, which have terminal wires which are soldered into appropriate holes in the printed-circuit boards. To assemble such printed-circuit boards manually, the terminal wires must be threaded into the appropriate holes, and the component must then be pressed into its final position. This often causes terminal wires to be bent. To avoid this, the invention provides a method and device in which the terminal wires (5) are threaded vertically downwards into the holes (1) of the printed-circuit board by guide pins (3) and an assembly frame (12), and the guide pins (3) are provided with V-shaped notches (8) to centre the terminal wires (5). <IMAGE>

Title: Process for producing nickel powder by means of partially oxidised natural gas
Inventor: FABER PETER DR
IPC: C22B23/02
Filed: 1985-09-27
Abstract: The natural gas, used in the parent patent for producing metallic nickel powder, is mixed, relative to its proportions of saturated hydrocarbons, preferably methane, with gaseous carbon dioxide. At 400-500 degrees C over a nickel catalyst, the gas mixture is largely converted to carbon monoxide and hydrogen according to the general equation  CnH2n+2 + n CO2 -> 2n CO + n+1 H2 The gas enriched with CO and H2 is then more suitable for the reduction of the NiOx according to the process of the parent patent than the unreformed natural gas itself. The reaction can also take place directly on the NiOx.

Title: Spray gun, in particular high-pressure spray gun for high and extremely high pressures
Inventor: REDMERS KARL-HEINZ
IPC: B05B1/30
Filed: 1986-03-29
Abstract: The invention relates to a high-pressure spray gun with a shut-off valve between a connector for pressure medium and a nozzle pipe. The shut-off valve has a valve-closure plunger, which is actuatable via a trigger lever, with a sealing collar and a fixed valve-sealing seat, penetrated by the valve-closure plunger, with a sealing edge assigned to the sealing collar. The valve-closure plunger is guided in a guide bush arranged between the shut-off valve and the nozzle pipe. The guide bush has guide channels, leading from the shut-off valve to the nozzle pipe, for the pressure medium entering the guide channels and emerging into the nozzle pipe when the shut-off valve is open. Furthermore, the valve-closure plunger is hydraulically compensated, so that work can be carried out with low opening and holding forces, obtaining a smooth transient function and avoiding sudden opening. <IMAGE>

Patent DE-3619373-A1 (DE)
Title: Control device for variation of the conveying capacity with constant compression and conveying pressures in the compaction and conveying of pulverulent or pelletized solids, suspensions or melts with the aid of screw machines or extruders with connected conveying channel or extrusion die, at constant drive speed, by axial displacement of the screw and, matched thereto, variation of the resistance characteristic of the connected mould channel
Inventor: HORRIGHS WOLFGANG DR ING
IPC: B29C48/45
Filed: 1986-06-09
Abstract: For the variation of the conveying capacity in screw machines or extruders, the speed regulation is usually used, which, however, is associated with a variation of the conveying and compression pressure, as a result of which products with extremely variable consistency are produced. The regulation of the material flow rate by axial displacement of the screw, presented here, on the other hand effects a variation of the screw characteristic and a variation of the resistance characteristic so that, with a mutually matched reciprocal effect between these two characteristics, a variation of the conveying flow rate can be obtained at constant compression pressure, it being possible additionally, in a covering part, to exert, by means of changed screw parameters, a selective influence on the screw characteristic and, by means of an adjustable throttle device, a selective influence on the resistance characteristic.
Patent DE-3619704-A1 (DE)
Title: Antenna arrangement for diversity reception in the windowpane of a motor vehicle
Inventor: LINDENMEIER HEINZ PROF DR ING
IPC: H01Q1/12
Filed: 1986-06-12
Abstract: The invention relates to an antenna arrangement for diversity reception, preferably for the frequency band of metric and decimetric waves, in the windowpane of a motor vehicle. The windowpane is surrounded by a metallic frame which has two approximately straight sides which are joined together in a corner of the frame with an enclosed angle in the range between 30 degrees and 150 degrees. Two antenna conductors are fitted there, each of which is guided essentially parallel to one of the two sides, in each case at a suitable distance over a length of at least 1/10 of the lowest operating wavelength. At their mutually facing ends, the two antenna conductors together with the adjacent connection to the metallic frame in each case form the antenna connecting point of a receiving monopole whose length is in each case suitably selected. The two antenna connecting points are connected to the two inputs of an input coupling circuit which has two or three outputs. Two outputs supply voltages which are in each case proportional to the reception voltages at the associated connecting points of the two monopoles. A voltage which is proportional to the difference between the reception voltages at the antenna connecting points can be formed with the aid of a third output. <IMAGE>

Title: Device for outputting voice without mechanical parts
Inventor: WANISCH THOMAS J
IPC: G10L19/00
Filed: 1986-09-02
Abstract: To achieve electronic voice storage and reproduction, a counter is used for generating the addresses for a RAM (random access memory). When recording, the counter at the same time controls an analog/ digital converter. The digital values determined are stored at the memory location addressed in each case by the counter. During reproduction, the counter retrieves the stored values from the RAM. Using an R2R network which is also utilised in the analog/digital conversion, the values are reconverted into analog voltages and output via a loudspeaker.
