Patent DE-2952122-A1 (DE)
Title: Speech controlled telephonic communication channel - employing digital filters and comparators to set reception and transmission channel damping
Inventor: BALANESCU ALEXANDER DR ING
IPC: H04M9/10
Filed: 1979-12-22
Abstract: The circuit overcomes the problem of correct input and output damping when both parties to a connection speak simultaneously. The microphone (M) output is amplified (MV) and, via the adjustable damping circuit (SD), fed to the transmitter amplifier (SV) and switching circuit (GS). A tapping from the microphone amplifier output goes to a null detector (SN). A comparable signal from the loudspeaker amplifier (LV) in the receive channel (EK) also goes to a null detector (EN). The null detections are all counted (SZ,EZ) and applied to a coincidence gate (KG). These items together form a correlation filter (KF). The filter output is integrated (IG) and ultimately placed in a memory (ROM) from where the null coincidence data is used to affect the setting of the damping circuits (SD,ED). Because the integration is not instantaneous, level detector circuits (SS,ES) setting of maximum or minimum damping. The feed from the receiving channel is time delayed (VG) by up to 250 microseconds.

Title: Knock detection in IC engines - using vibration sensor with vibrating mass exerting force on dielectric medium
Inventor: BETZ DIETER DIPL ING
IPC: G01H11/06
Filed: 1980-02-22
Abstract: A knock detection sensor has a base (10) attached to a component of the engine transferring the knock vibration and a vibrating mass (12). It is partic. simple, robust, and cheap to make and uses economical materials. The sensor produces active signals which can be directly processed. Dielectric material placed between the base (10) and the vibrating mass (12) produces an active signal when the mass exerts a force upon it. The signal is fed to an amplifier (15). The dielectric material is in the form of an intermediate layer (13) and the active signal is extracted from between the mass (12) and the base (10). Alternatively, a disc-shaped ceramic capacitor between the base and the vibrating mass produces the active signal when knock vibrations occur.

Title: Steam power generator with feedback - produces mechanical work exclusively from super heated medium expanded adiabatically
IPC: F01K21/00
Filed: 1980-03-13
Abstract: A steam power generator has exhaust heat feedback to the steam circulation process. The mechanical work is extracted exclusively from the superheat. The converted heat not used to produce work during the conversion process is permanently fed back to the steam circulation process. A liq. with a high or a low boiling point, such as water ammonia, is transformed into superheated steam or into the gaseous condition by the absorption of external heat. The superheated steam is fed to the rotary or reciprocating machine where it is first kept at constant pressure and then expanded adiabatically to the upper limiting curve of the working medium used. It is then compressed and condensed to a constant expansion end pressure. The medium is then fed back via a high pressure pump.
