Patent DE-2850065-A1 (DE)
Title: Cine camera with reduced noise level - uses three separate drive motors supplied with control pulses from common clock generator (OE 15.3.79)
Inventor: BAUER FRITZ GABRIEL
IPC: G03B19/18
Filed: 1978-11-18
Abstract: The cine camera uses a separate motor for the film transport mechanism, the rotary shutter mechanism and sprocket wheel. The three motors are harmonised via a control circuit. Pref. each motor comprises a stepping motor controlled by pulses from a common clock pulse generator. A frequency converter stage is coupled between the latter and at least one of the motors with a respective drive stage preceding each motor together with a switch for deactivating the motor. This switch may be coupled via a control device to a comparator for comparing signals representing the actual and required motor speeds.

Title: Electric supply protection for work tables - using matching network and threshold switch disconnecting supply via contact in case of overvoltage
Inventor: PREUSSE FRITZ
IPC: H02H3/20
Filed: 1979-01-29
Abstract: The electric supply system to worktables in physics laboratories of schools institutes or training establishments must be protected against overvoltages. A main contactor connects the main distribution board to the supply. A great variety (d.c. or a.c.) of voltages and currents are available at the sockets. They become available to the worktables by inserting jumpers with banana plugs. Each line is linked to a matching circuit with a high ohm resistor and two antiparallel diodes. If a common threshold switch detects the presence of an over-voltage it cuts out the main contactor by breaking the contact. This ensures full protection against electrical accidents.

Title: Generator for electric vehicle with sinusoidal output - uses frequency control and forms approximation to ideal wave by simultaneous variation of polyphase outputs
Inventor: SCHUSTEK SIEGFRIED EMMERICH DI
IPC: B60L13/00
Filed: 1979-01-31
Abstract: A generator supplies the power to drive an electrically-driven motor vehicle at a given speed. It is a polyphase nominal voltage generator with sinusoidal outputs with infinitely variable frequency control. There is common amplitude control for all the output voltages to obtain max. output from the motors. It suppresses the unsymmetrical components of the voltage. The sinusoidal wave is approximated by the output voltages with relative phase displacement and amplitudes which can be varied in common. The final outputs are passed through controlled rectifiers. The nominal value generator can be used on electric passenger vehicles or freighted vehicles. It can also be used on building sites and for tracked drives.

Title: Opto-electronic relay for telephone exchange - has transistor blocking too high current to LED transmitting light to receiving element
Inventor: EMDE KURT-LOTHAR DIPL ING
IPC: H03K17/795
Filed: 1979-06-19
Abstract: An opto-electronic relay is for a telephone exchange or can act as a special type of switch. A transistor prevents too high currents from reaching a l.e.d. used to transmit light to a receiving element. The base of the transistor is connected to the junction of the l.e.d. and a resistor forming a series circuit of base-emitter-resistor. The latter is shunted by the emitter-collector patch of the transistor. This emitter-collector path is itself shunted by a leakage resistance. A collector resistor can be inserted between the collector of the transistor and the series circuit of base-emitter-resistor. The leakage resistance can be coupled between the collector of the transistor and the collector resistor. The leakage resistance can be provided as a variable resistor.

Title: Gas pipe safety seal - comprises plastic ring screwed into union with half-shells spring-loaded shut
Inventor: HOHMANN RUDI
IPC: F16L41/04
Filed: 1979-07-17

Title: Hydraulic prop assembled mine support frame - has side draw rods for cap and shield convergence and block length setting
Inventor: SMITH JOHN CAMBRIDGE
IPC: E21D23/00
Filed: 1979-11-27
Abstract: There are hinged caps and base plates on the hydraulically extensible props making up the support frame in a mine. There are rear end swivelling shields, and pressure blocks hinged to the cap and shield so that they run at an angle to the frame centre line, providing cap resistance to displacement. Draw rods (11) are attached at the frame sides, between the cap (3) and shield. These provide for mutual convergence of cap and shield, and determination of the extension length of the pressure blocks (12), and thus the max. interval between cap and shield on each side of the frame. This is effective in spite of relatively unfavourable pressure blocks' position, with props withdrawable into a prescribed position on removal from the roof.
