Title: Electronic switch for selection pulse circuit in telephone - has thyristor turned on by resistor and off by transistor driven from RE circuit
Inventor: RALL BERNHARD DIPL ING
IPC: H04M1/31
Filed: 1978-04-19
Abstract: The electronic switch consists of a thyristor (1) with its gate/anode path shunted by a turn-on resistor (3) and its gate/cathode path shunted by a controlled semiconductor (4).

Title: Low temp. gas mixt. sepn. process - uses only additionally compressed gas stream in expansion machine
Inventor: ROHDE WILHELM
IPC: F25J3/04
Filed: 1978-12-16
Abstract: The low-temp. gas mixt. sepn. process uses two-stage rectification, the mixt. being compressed and divided into two streams. One of these is led to the high-pressure section of a two-stage rectification column, and the other is further compressed and cooled by heat exchange with sepn. products. A further stream is passed through an expansion machine and led to the low-pressure section of the column. Only the additionally-compressed stream is used as this further current. The output of the expansion machine can be transmitted at least partly to the compressor effecting the additional compression operation.

Title: Rotation and revolution rate measurement - using sagnac effect and circularly polarised light faraday phase shift control
Inventor: ULRICH REINHARD DR
IPC: G01P3/36
Filed: 1979-02-22
Abstract: The method and arrangement are for measuring rotations and revolution rates using the Sagnac Effect in a closed light path mainly consisting of an optical fibre and subject to rotation are designed to eliminate as far as possible the influences and non-linearities of the evaluation electronics and instabilities in the measurement system which can degrate measurement accuracy. Coherent partial light currents coupled into the fibre ends are recombined after passing through it. The rotation speed is derived from the combined light current intensity which depends on the phase shift of the interfering currents. Both partial light beams are subjected to a phase modulation. The detector output signal is rectified with phase reference to the modulation frequency. The oppositely circulating beams are circularly left or right polarised. The detector rectifies output controls a magnetic coil round the fibre so that the rotation phase difference and the Faraday phase difference sum to a whole number multiple of 2TT.

IPC: H01H9/16
Filed: 1979-07-06
Abstract: The monitor is particularly intended for sulphur hexafluoride insulated outdoors power circuit breakers, with at least one switching pole at high voltage. Near one switching pole (24,26) is mounted a leakage detector (46) which controls, in case of leakage, a light beam transmitted from high voltage to earth.

A light source (36) may be connected to the high voltage, which may be masked or exposed by a shutter segment actuated by the leakage detector. An insertion of a convex lens may be used for focussing the light source emission to the optical fibre input. Two optical fibres may be used when the light source is at earth potential, one fibre transmitting the light to a mirror system feeding the second fibre, leading to the photocell.
