Title: Incremental setting system for magnetic core store - is for comparing output voltage with reference voltage to obtain setting pulses
Inventor: SETTFORS JAN DIPL ING
IPC: G11C11/06
Filed: 1976-01-14
Abstract: The incremental setting system for a transfluxor (RTM) store has the output voltage of the latter compared with a reference voltage, so that setting pulses are supplied to the store until the two voltages are the same. Together with each setting pulse, at least two interrogation pulses are applied across the interrogation winding, with only the latter of the subsequent output pulses used to determine the output voltage. Pref. the setting pulses and the series of interrogation pulses associated with each are supplied by a single source. The setting pulses are pref. supplied to the setting winding via a NAND circuit and a diode resistor and capacitor circuit, controlling a transistor, with its collector connected to the setting winding.

Title: Single line with DC fed repeaters - with HF and DC fed to single transmission line with filter eliminating resonances and hum pick=up
Inventor: ENGLERT REINER ING GRAD
IPC: H04B3/44
Filed: 1976-08-27
Abstract: The branch junction for an h.f line permits the feed-in and take-off of an h.f current a supply current, with a capacity in the HF line and an inductance in the supply line and a blocking capacitor between the inductance and earth, with an additional resistance in series with the blocking capacitor. The arrangement is useful with long transmission lines incorporating amplifiers, to feed the supply currents for these amplifiers through the single HF/DC line. The presence of the resistance results in a considerable attenuation of any resonances or hum pick-up on the line. The effect may be enhanced by providing an additional inductance in series with the resistance.

Title: Chilled ready unexpanded dough contg. chemical blowing agents - packed and stored in rigid pressure-resistant containers
Inventor: REINERS FRITZ DIPL CHEM
IPC: A21D6/00
Filed: 1976-10-02
Abstract: Prepn. of chilled, ready-to-bake doughs, contg. chemical blowing agents, comprises packing and storing the raw unexpanded doughs in rigid-walled, pressure-resistant containers. The raw doughs are prepd. from standard raw materials by merely mixing and kneading. Quick transfer of the raw, unworked doughs to pressure-resistant containers, shortens processing times e.g. from 25-35 min to 5 min. and minimises CO2 loss. increase in lactic acid bacteria and formation of Na2HPO4.12H2O crystals, when using NaHCO, and Na4P2O7 as blowing agents. Storage in the given containers improves gas retention of dough, probably by forming a protective outer skin through internal pressure in container.

Title: Automatic document reading for radio processor computation - using scanning head unit for max. possible reading positions on master indicator
IPC: G06V30/146
Filed: 1976-11-03
Abstract: Automatic document reading enables rapid computation in a processor of the regions of the document to be examined. It avoids the necessity of complicated and exact document indicator marking devices and facilitates the handling of different document types, e.g. lists, questionnaires etc. The processor works with a scanning head input unit such that a max. number of possible reading positions is defined on the document by first scanning a master bearing only positional indicators. The processor computes the positions and stores them. A second document is then scanned with data present in the intended positions, and the processor assigns values to the used positions which are then evaluated on the succeeding documents.

Title: Device measuring angle of rotation of shafts etc. - has toothed disc attached to shaft providing signals for magnetic data pick=up
Inventor: HELWICH PETER-JUERGEN ING GRAD
IPC: G01P3/48
Filed: 1977-09-23
Abstract: The device to measure angle of rotation uses a voltage-controlled control-frequency transmitter which supplies pulses to a counter. The counting frequency of the transmitter is adopted as a function of the mean frequency of the pulses received. When a received pulse is input, a store takes over the content of the counter, so that at a constant frequency of the pulses received the store has the same counter state at any given time. A D/A converter may be used at the store output. The measuring signal may be defined by tooth divisions of the toothed disc.
