Title: Location method for surface vehicles - involves receiving radio signals from vehicle by several separate receiving stations
Inventor: DREBINGER KLAUS
IPC: H04Q7/38
Filed: 1974-12-20
Abstract: Received signals from the outlying stations are transmitted over fixed wire lines (12, 13, 14, 15, 16) to a central station where they are evaluated by the hyperbolic method; errors due to propagation time between the receiving stations and the central station are eliminated by a correction derived from location of a fixed reference transmitter as in 21 37 846. In order to obtain correction values at least two separate reference transmitters (V1-V6) are called and located. A mean value is formed from correction values for the different reference transmitters, and are used as calibration for vehicle location. The use of a large number, e.g. 6 outlying stations enables the elimination of ambiguities in the results.

Title: Natural gas liquefaction process - with circulating medium leakage compensated by higher boiling liquid fraction from feed stock
Inventor: ETZBACH VOLKER DIPL ING
IPC: F25J3/02
Filed: 1975-01-24
Abstract: In a closed refrigeration circuit for the liquefaction of natural gas, the circulating gas mixture is compressed, cooled and liquefied in several stages by partial condensation. The natural gas is partly split into fractions during its liquefaction. The liquid fraction consisting of hydrocarbons with a higher boiling point are recycled into the refrigeration circuit, after it has it has been evaporated and heated in a heat exchange with natural gas and the circulating medium. The corresponding part of the circulating medium is extracted from the closed circuit. This compensates for the leakage of components of the circulating medium. The capital investment and the operating costs for storage tanks of the individual components are saved.

Patent DE-2523997-A1 (DE)
Inventor: ETTER PETER
IPC: H02M1/096
Filed: 1975-05-30
Abstract: In the case of converters having power thyristors, a plurality of successive triggering pulses for the individual thyristors are required in many applications, for example in the case of parallel-connected thyristors in order to ensure the current distribution to all the thyristors. This also applies to triggering circuits having a light-controlled thyristor in the gate-cathode circuit of the power thyristors. Complex arrangements are normally required for multiple-pulse triggering circuits. The object of the invention is to create a comparatively simple and reliably operating multiple-pulse triggering circuit using light-controlled triggering thyristors. In order to achieve this object, a tuned circuit, whose oscillations produce the required multiple triggering pulses with successive charge reversal of the capacitor (6), is formed in the gate-cathode circuit of a power thyristor (1) with a light-controlled triggering thyristor (9) and with a capacitor (6) for storing triggering energy, by means of series connection of a suitably dimensioned inductance (5) to the capacitor (6). If the damping of the tuned circuit is suitably weak, it is possible to produce a sufficient number of successive triggering pulses. In addition, the triggering current can be adjusted and can be kept virtually constant by means of the energy stores of the tuned circuit. <IMAGE>

Title: Telephone line calling state detector - uses decoupling rectifier to avoid line damage
Inventor: ANTRITTER JUERN DIPL ING
IPC: H04Q3/00
Filed: 1975-09-24
Abstract: When the loop is closd by a subscriber, calling state is detected by a capacitor charged to the potential difference between the wires and inserted between the subscriber line pulse generator output and the input of a voltage measuring device. It is connected through decoupler which reduce feed-back from pulse generator to the subscriber line to a safe level. The decoupler consists of resistors sensitive to current polarity, e.g., rectifiers (G1), whose resistance is low for currents charging the capacitor (C1) to the potential difference between line wires. But they block the pulse voltage from the pulse generator (Tr2 etc.). The subscriber line may be connected to the rectifiers via a low pass filter.
