Title: Operation of converter fed motor during supply interruptions - includes alternative DC circuit path controlled by thyristor
Inventor: ISHIBASHI HIDEO DIPL ING
IPC: H02P27/06
Filed: 1976-08-19
Abstract: A converter fed motor is protected against sudden over-currents when the supply to a motor circuit is restored after a brief interruption. Normal operation of the speed controlled motor (5) is via a controlled rectifier (2) and a self commutating inverter (4) with a smoothing choke (3) in the d.c. link between the two. If the supply system (1) voltage falls below a predetermined level a thyristor (14) across the d.c. circuit is triggered and the inverter control initiates a reduction in frequency. The motor thus changes to generator operation, falling in speed, and the loop current flows through the thyristor (14). The circuit maintains the machine current, and thus machine flux, and on restoration of the supply there is no sudden inrush current. As the rectifier (2) voltage rises again the thyristor (14) is extinguished and the control circuits revert to normal. Motor operation is restored and the machine accelerates back to its set speed.

Title: Hangar ventilation shutter operating mechanism - has hand winch with detachable counterweight sections on cable
Inventor: KONZER MANFRED
IPC: B64F1/36
Filed: 1977-05-25
Abstract: The mechanism is operated by a crank-handle-winch f which the traction cable traverses an idling pulley to anchor on the shutter. The lifting of the leaf is assisted by a progressively varying counter-weight. The counter-weight is split into segments which are progressively removed as the mass descends. In this manner the greatest assistance coincides with the maximum shutter moment being countered. The detachable segments may settle on intermediate supports as the mass descends. The geometry of the counterweight may be such that the primary mass passed through the intermediate supports during descent.
