Title: Overvoltage protection for inverter operating on DC HV - uses fast switching of charging resistor by thyristor
Inventor: KLOTZ HUGO DIPL ING
IPC: H02H9/00
Filed: 1977-03-11
Abstract: The inverter overvoltage protection circuit is principally for use in suburban electric trains. The inverter (1) is connected to the dc traction supply (2) through a buffer capacitor (5). At start-up a charging resistor (4) is in series with the capacitor. On reaching a preset voltage a detector (8) triggers a thyristor (7) to bridge the resistor (4). The inverter is now operational. Should a voltage transient occur the detector (8) triggers a commutating circuit (9, 10) and the thyristor (7) is extinguished. The resistor (4) is reinserted and absorbs the voltage transient. On reaching an acceptable voltage level the detector retriggers the thyristor and the inverter returns to normal operation. The protection is also effective in preventing feedback into the traction supply.

Title: Double phase acoustic corrector - has small transverse deflector preventing flow back of sound so that it can be added
Inventor: VOGT EBERHARD
IPC: H04R1/28
Filed: 1977-06-13
Abstract: The corrector lies transversally at the beginning of the phase channel and diverts the sound of several bass loudspeakers into the channel. The production tolerances of the loudspeakers cause small differences in transient processes between the loudspeakers so that the sound radiation from different loudspeakers is staggered in time. The sound node is so shifted, that one loudspeaker oscillates in the phase channel, while others operate like in a closed cabinet. Deflection of the sound into the channel prevents a flow-back. The sound from several loudspeakers can be added, without interfering with each other. It is even possible to disconnect one loudspeaker without upsetting the operation of the rest.
