Patent DE-2351106-A1 (DE)
Title: DC motor protection and starter control - guards against voltage surges, short circuits, switch arcing and supply variations
Inventor: KLOTZ HUGO DIPL-ING
IPC: H02H3/04
Filed: 1973-10-09
Abstract: DC electric motors and their starter systems are protected by providing a variable shunt path across the starter and motor circuit. The starter resistance can be short circuited by a parallel thyristor coupled to the current lever control. A further thyristor at the lower end of the shunt network acts as a break to the shunting thyristor. Threshold switching of the thyristors is controlled by a transformer coupled to a network across the motor. Indication of operation of the protection circuit is obtained from a transformer across the shunt line operating a relay.

Title: Ram jet propulsion for boat - with cylindrical valve which requires small gas vols. and displaces min. water forwards
Inventor: VOSS HANS
IPC: B63H11/12
Filed: 1973-10-15
Abstract: The ram jet has a combustion chamber in which the fuel is ignited to generate gases. A hollow, cylindrical shutter coaxial to the centre of the jet has a profiled leading edge fitted with a circular gasket. The ends of the cylinder are guided in narrow ducts so that only a small gas vol. is required to drive it forward until the leading edge is forced against the inside of the entry duct to seal off the water intake. A small amount of water is expelled forward thus releasing more gases to provide the propulsion. The gases are collected in a chamber and passed intot he outer water jacket through a duct opened when the valve is slid forward. When the valve is closed the fuel intake is also stopped.

Title: Directional relay for AC networks with two supplies - has differential quotient of clipped AC current triggering indicating relays
Inventor: GEIGER FRANZ DIPL ING
IPC: G01R19/14
Filed: 1974-03-16
Abstract: The directional relay, for a.c. networks with two supplies, has the a.c. voltage and current and the 180 deg. phase-shifted a.c. current clipped by zener diode circuits into trapezium-shaped current waveforms. The positive differential quotient of the trapezium current waveform during the positive half wave triggers the direction indicating relays. The advantage of the circuit is its direct processing of the a.c. voltage and a.c. current which allows the whole directional relay circuit to be manufactured more economically than existing types because the number of electronic components is less.
Patent DE-2413555-A1 (DE)
Title: Cylinder lock operated by magnetic key - rotary magnets prevent radially moving locking bar moving
Inventor: BOEVING EGON
IPC: E05B47/00
Filed: 1974-03-21
Abstract: Permanent magnets (34) embedded in the key rotate the cylinders (17, 18, 19) about pivots (16) by action on the associated magnets (21). When all magnets are aligned the slots (22) face the projections (23) on the locking bar (11) which can then slide radially inwardly against the pressure springs (24). The inward movement of bar (11) is produced by the rotation of the barrel which brings the chamfered edge (10) of the bar into contact with the internal surface of the cylinder (1). Returning the key and withdrawing it rotates the cylinders (17) so that the projections (23) do not register with slots (22) and the locking bar cannot move inwards to release the barrel. Any attempt to force the lock causes the projections to press on the magnetic cylinders which cannot then turn.

Title: Loose thermoplastic granulates prodn - by shearing thermoplastic from nozzles with cooled, rotating knife, and projecting particles into ring of fluid
Inventor: HEIL EDUARD DIPL ING
IPC: B29B9/06
Filed: 1974-11-26
Abstract: A thermoplastic mass is granulated by extruding it through a nozzle plate into the chamber pressurised by gas and filled with fine droplets of fluid, of a water-ring cutter. On emerging from the nozzles, the thermoplastic is sheared off by cooled, rotating knives, the particles being superficially chilled, projected centrifugally into the ring of fluid set up on the inner wall of the chamber, and washed out by it. Unwanted cooling of the extrusion head is prevented by the continuous circulation across its face of a stream of gas picked up by the revolving knives and rid by centrifugal force, by any droplets of fluid. There is no adhesion between the granules or linkage by filaments. Excessive wear on knives and extrusion plate is avoided.

Title: Frequency multiplier with single sideband signal generation - is multiplied and downward mixed for filtering to obtain wanted integer multiple
Inventor: ENTLEUTNER SIGISMUND DR ING
IPC: H03B19/00
Filed: 1975-01-08
Abstract: The frequency multiplier, for multiplying an input signal by a constant selectable integer, produces a single side-band signal from the input signal and a carrier signal. The multiplied input signal is obtained by multiplying and downward mixing with the integer-multiplied carrier and by separating out unwanted multiples of the input signal. The advantage lies in avoiding unwanted multiples and input signals in the required multiple frequency band. The output of the modulator is multiplied and can be mixed with the output of the same oscillator whose divided output is used to form the single sideband signal or with the output of a separate oscillator.
