Title: Ballast for fluorescent or gas-discharge tubes
Inventor: DUM HERMANN DIPL ING
IPC: H05B41/00
Filed: 1982-09-13
Abstract: An electronic ballast is described for a fluorescent or gas-discharge tube having a capacitor with a relatively high capacitance as an intermediate energy store. In this arrangement, the capacitor (14), which is used as the intermediate energy store, and a fuse (13), which is connected in series therewith or is integrated into the capacitor (14), are arranged on a carrier (11) which is provided with contact pieces (3). The contact pieces (3), which are preferably constructed as plug-in contacts, can be connected to the normal ballast (1) and/or to mating contacts (4) connected to the fluorescent or gas-discharge tube (7), in order to ensure that the capacitor can be replaced easily, without tools. <IMAGE>

Title: Device for storing low-temperature heat in the backfilling of trains of pipes
Inventor: OEHLER ERNST AUGUST
IPC: F28D20/00
Filed: 1982-09-15
Abstract: The patent application under the abovenamed designation relates to storing low-temperature waste heat inside the backfilling, which is thermally insulated from the outside, in trains of pipes leading to external consumers. It is preferred, for example, that the feed is from cooling water circuits of industrial undertakings and power stations. The aim of this patent application is also that in the event of interruption of the low-temperature feed into the train of pipes, it is possible to provide a continuous supply from the backfilling store to the external low-temperature heat consumers for the time of the interruption. A pipeline network constructed in accordance with the patent application, which stores and transports low-temperature waste heat, can be used for the purpose of continuous heating even in the event of specific possibilities of interruption to the supply of heat, e.g. for swimming pools, greenhouses, schools and dwellings, for service water etc. The efficiency can be further increased by fitting low-temperature water heat pumps downstream, which can be operated with a substantially better performance coefficient than the heat pumps known so far.

Title: Device for calibrating extruded plastics profiles
Inventor: GOEBEL ALBERT
IPC: B29C48/90
Filed: 1983-01-19
Abstract: A device for calibrating extruded plastics profiles, in which the gauge surfaces (6) of the calibration form (1) are connected via passages, for example slits and/or bore holes, to a vacuum pump (9) and the inlet and outlet of the calibration form (1) are each sealed by a hydraulic seal (3 and 4), is constructed in such a manner that the delivery rate of the vacuum pump (9) is determined only by the level of the vacuum to be produced in continuous operation. To this end, a large-volume container (11) as water separator is connected between the suction side (8) of the vacuum pump (9) and the associated vacuum connection (7) for the calibration form (1). In the container (11) the water drawn off from the calibration form (1) by the vacuum stream is separated and kept away from the vacuum pump (9). For start-up operation, a high vacuum can be briefly generated in the container (11), which vacuum facilitates the application of the plastics profile (2) to the gauge surfaces (6) of the calibration form (1). <IMAGE>

Inventor: GITTLER GUENTER
IPC: H04N3/15
Filed: 1983-03-14
Abstract: The invention relates to a circuit arrangement for eliminating the effects of external light in semiconductor imaging devices of the second generation. It is used in measuring, handling and robot technology and here particularly in electro-optical measuring systems which require an exclusion of the effects of external light. The aim of the invention is the creation of an electro-optical measuring device comprising a laser as transmitter and a photo-sensitive high-resolution semiconductor imaging device as receiver, which, with little complexity, provides for reliable signal detection with strong effects of external light. The object is to be achieved to find possibilities for processing the opto-electronic received signal. This is done by a novel circuit arrangement being used for driving the semiconductor imaging device of the second generation. Using this circuit arrangement, an unknown effect previously not provided within the semiconductor imaging device can be utilised. The external light is suppressed without additional complexity, has high reliability and is characterised by low energy consumption. <IMAGE>

Title: Measuring system for detecting the relative and absolute movements between rapidly rotating shafts
Inventor: WALZER WINFRIED DIPL ING
IPC: G01P3/60
Filed: 1984-01-28
Abstract: A measurement problem that frequently occurs in all fields of technology is the exact detection of torsional play, angular differences and torsional vibrations between two rotating shafts at full speed and under load. A computer-assisted high-resolution measuring system has been invented for the purpose of continuous detection of the variations in differential angle between two rotating shafts. The apparatus consists in its present version of the following units (Fig. 1):     - incremental rotary transducer   - differential angle measuring instrument   - intermediate store for measured data   - microcomputer   The measuring system can be applied to all measurement problems in which there is a need for an analog or digital measurement signal for the variation in the differential angle of rotating machine parts. It is suggested, in particular, for geometrical, kinematic and dynamic analysis of shaft joints, clutches/couplings and transmissions of all sorts. The modular construction of the measuring system omits use as a total system, or else of only individual subassemblies, resulting in a large degree of flexibility in any possible application. <IMAGE>

Filed: 1984-06-12
Abstract: AgSnO2-based contact materials with Bi2O3 and CuO as further metal oxide additives have already been proposed. In these, the volume fraction of metal oxide should be between 10% and 25% with an SnO2 volume fraction of >/=70% of the total oxide quantity. It is proposed to select the SnO2 mass fraction specifically in the range from 4% to 8%. The Bi2O3 mass fraction is here between 0.5% and 4%, and the CuO mass fraction is between 0.3% and 1%, the remainder being silver in each case. Contact pieces having surprisingly good electrical properties can be manufactured from such materials.

Title: Intensive mains scouring unit for grains
Inventor: HAUSSIG RAINER DIPL ING
IPC: B02B3/08
Filed: 1984-07-07
Abstract: The invention relates to an intensive mains scouring unit for grains, preferably wheat and rye. The aim is to develop a machine which achieves a high, controllable working effect with minimum use of material and energy and in a simple manner requiring little servicing and maintenance. This is made possible according to the invention in that grain distributing and grain accelerating elements, water atomising elements, damming, processing and compression elements are arranged on a rotor. Enclosing this at a distance, a water-tight working casing, which can be opened when required, radially delimits the processing chamber, in which an intensive swirling of mains water and a curtain of grain takes place in the upper region and an automatic damming of material arises in the lower region, leading to further mechanical distribution and working-in of the mains water into the grain mixture. The working effect can be adjusted with respect to wetting-out or bran stripping by the metered water introduction, the adjustable damming effect, and the use of different rotating or stationary working elements connected to the casing. The stream of processed grain flows out downwards through a discharge hopper. <IMAGE>

Patent DE-3436555-A1 (DE)
Inventor: HARTMANN UWE ING GRAD
IPC: H04N3/185
Filed: 1984-10-05
Abstract: A combinatorial circuit component for television sets with an overload protection circuit on the primary side and a secondary-side regulating circuit and starting circuit with final disconnection of the mains section. The protective circuit, which comes into play in the event of anomalies on the primary side, causes a jump in the negative voltage on the secondary side. This is compared with a secondary (standby) voltage, created independently of the combinatorial circuit, in a comparator, which supplies a control voltage to which the secondary protection circuit responds thus interrupting the excitation of the switch in the mains section.
