Title: Oil escape signalling device - has double float, one floating on water, and other on oil and uses change of position to trip signal
Inventor: STUECKL HEINRICH
IPC: G01F23/64
Filed: 1977-06-28
Abstract: The device signals oil already escaped and floating on the water surface, thus preventing heating oil penetration into ground water or into sewage system. It is intended for all tank rooms, heating cellars and most of all for waste water channels. It reacts to oil only, since it floats on water surface and indicates only oil. Shifting of a float position in two liquids with different densities trips the switching processes, e.g. a alarm on and a waste water pump off. These processes are tripped by the tilting of a mercury switch.

Title: Carrier wave demodulator suppressing unwanted modulation products - has sample and hold circuit which switches signal to capacitor in synchronism with carrier
Inventor: VOLEJNIK WILHELM DIPL ING
IPC: H03D1/22
Filed: 1977-07-29
Abstract: The carrier-wave demodulator is designed to allow certain modulation products to be suppressed whilst retaining simplicity. The carrier wave (Q) is passed to the input of a sample and hold circuit where it is switched (S) in synchronism with its carrier frequency through to a capacitor (C). Alternatively, the sample and hold circuit may be constructed on pushpull principles if two input signals are present. In this case there is still only one capacitor but now two switches. The two signal sources are connected in series and their common point earthed.
