Title: Space heater for enclosed substation - has its operation controlled by dew point detectors with peltier element in coolest part of substation
Inventor: BAUMGAERTL ULRICH
IPC: H02B7/06
Filed: 1975-08-01
Abstract: The purpose of the circuit is to save energy by switching off the heater when there is no danger of moisture condensing out onto the insulator surfaces in a substation. A heater (8) is under the control of a dew point sensor (9) whose detecting element is subjected to more intense cooling than the rest of the installation. In consequence moisture is condensed on the detector before the dew point for the rest of the enclosure is reached. The equipment is thus safeguarded as the heaters will be on in time to prevent condensation. When the dew point is below the detector temperature the heaters are again switched off. Peltier elements may be used as detectors and their output, suitably amplified, is used to operate the relay switching the heater.

Title: Signal transmission by alternating voltage - using modulation of half cycle crest value by individual clipping of half cycles
Inventor: MIESSL ROBERT
IPC: G05D23/24
Filed: 1976-05-28
Abstract: The signal transmitter employs one or more wires to convey the signals. The signal is generated by altering the magnitude of the half cycle crest voltage to specific values. It is detected by monitoring the level of the incoming voltage crests at the receiving end. In a typical installation the crest voltage may be set by clipping the particular half cycles (positive or negative or both) with a zener diode circuit to a predetermined value. By use of several diodes with differing zener voltages connected to a selector system a variety of information can be sent down one wire. The receiver may employ a complementary set of zener diodes to check the incoming voltage and actuate the particular circuit demanded by the signal.
