Title: Vehicle course measurement system - uses earth's magnetic field and has steering angle sensor operating during disturbances of field
Inventor: SZCZESNY WILFRIED ING GRAD
IPC: G01C21/28
Filed: 1979-07-06
Abstract: The vehicle course measurement arrangement contains a first sensor deriving a signal corresp. to the magnetic heading from the earth's magnetic field. It is an economical device providing accuracy good enough for navigation even with variations in the earth's magnetic field. An additional sensor which is stable over short periods acts as a course variation sensor. A correction signal is derived from the two sensor signals such that the heading is essentially derived from the sensor when disturbances occur in the earth's magnetic field. The course signal is obtained by adding the previous course signal' the heading increment, second sensor output' and the correction signal. The steering control angle is determined by the second course sensor which contains a pulse generator connected to the steering column.

Title: Profiled guide rollers for wet-treatment of fabric rope - have liquor drain channels to discharge liq. and prevent aquaplaning
IPC: D06B3/24
Filed: 1979-12-01
Abstract: Guide rollers for use in the wet-treatment of fabric in rope form, partic. in rope scouring machines, have a series of grooves or channels running across the surface, leading to apertures in the flanges at the ends of the roller. The grooves serve as drainage channels for entrained liquor separating from the fabric, and discharge the liquor in a way which prevents it from running back over the rope. This prevents an aquaplaning effect when running at high speeds with long liquor ratios and enables the roller to maintain frictional contact with the rope. Tension fluctuations in the rope are minimised, and the washing efficiency is improved.

Title: Price calculating balance with computer interface safety switching - responding only to defined range of keyboard input values
Inventor: ZIMMER WILHELM
IPC: G01G19/414
Filed: 1979-09-25
Abstract: A device recording the price of goods, esp. a price-calculating scale unit, contains a memory for price by goods and/or wt., a keyboard for memory dependent and independent pricing, a computer for price-wt. multiplication and price addition, and a multiple role display. A switching unit changes the computer interface connection from the memory output to the input device and vice-versa. The arrangement reliably prevents faulty keying operations which can easily arise in busy shopping periods. This is achieved without complicating machine operation by arranging that the switching element can respond only to a defined boundary value, in the keyboard input. As long as the value is not exceeded the computer is connected to the memory and each input corresp. to a code number.
Patent DE-3001132-A1 (DE)
Title: Telephone instrument for impulse type number selection - with switched low impedance path to facilitate subscriber identification by exchange
Inventor: LOSEHAND HELMUT DIPL ING
IPC: H04M1/31
Filed: 1980-01-14
Abstract: The circuit is intended to simplify the recognition of the subscriber when the hand set is lifted. A circuit comprising a resistor (R1) and two field effect transistors (FET1, FET2) is connected across the lines inside the instrument. The FET gates are connected to a control unit (AS). The FETs are of the depletion type and are in the conducting state when no gate voltage is applied. When the hand set is lifted the contact (gu) on the cradle connects the instrument to the exchange. The low recognition voltage is applied to a low impedance path (R1). When identified, the exchange switches on the operating voltage whereupon the impulse generator in the selector system (TWB) becomes active. Impulses are transmitted to the control unit (AS), rectified and applied to the FET gate circuits. The FETs become non- conducting and the path reverts to a high impedance state. Normal operation can then proceed. The FET controlled circuit bypasses the bridge rectifier (GB) in the instrument which has a high impedance tothe recognition voltage, and would not pass sufficient current to operate the exchange equipment without complicated extra circuitry.

Patent DE-3025718-A1 (DE)
Inventor: GROLMS REINHARD
IPC: G01S13/91
Filed: 1980-07-07
Abstract: In order to control, in particular the downhill braking of railway gravity shunting systems, it is important to know when the vehicles have been affected by the brakes. For constructional reasons it is not possible to arrange at the point of the brake at which the brake bars grip fully, a rail contact via which such a report could be triggered. This contact is always arranged in front of the brake and therefore, hitherto, has triggered the braking report too early. In accordance with the invention there is provision for a vehicle which travels over the rail contact (IG) when a preceding section of the brake is free, to input a length value, corresponding to the preceding section, into a pulse counter (IZ), and for the pulse counter to be subsequently reset incrementally in accordance with the forward movement of the vehicle. The resetting pulses (RI) are output here by a radar device (R) which detects the vehicle moving forward. Whenever the pulse counter (IZ) moves into the zero position, it is loaded with a length value which corresponds to the distance between the respective following axle and the axle which is travelling straight ahead. This length value was determined when the respective following axle actuated the rail contact (IG). The timing of the zero crossovers of the pulse counter (IZ) designates the times at which vehicles arrive at the effective braking range of the brake. <IMAGE>

Title: Anamorphic converter circuit for TV signals - has stages to modify video signal from cine film so that displayed image along one axis has dimensions changed W.R.T perpendicular axis
Inventor: BELMARES-SARABIA ARMAND
IPC: H04N9/11
Filed: 1980-08-02
Abstract: The beam index colour cathode ray tube has index stripes spaced apart across a run-in area of the screen which have a pitch equal to the pitch of index stripes in an image area. A predetermined number of the index stripes in the run-in area are counted as an electron beam scans them to preset colour control circuits to a predetermined condition as the commencement of scanning of the image area. A characteristic of the signal resulting from scanning of the index stripes may be used to begin the counting of the signal from a specific one of the index stripes in the run-in area other than the first one encountered by the electron beam. A broad index stripe is optionally provided at the outer perimeter of the run-in area. The broad index stripe raises the average signal level in that region to a high enough level to avoid triggering by noise.
