Title: Gain controlled amplifier for audio systems - delays input so that gain change takes place before input arrives
Inventor: KRAUS ULRICH
IPC: H03G3/20
Filed: 1976-01-20
Abstract: The gain-controlled amplifier, for LF sound systems, is designed so that its gain has already been altered by the time the input signal reaches the gain-controlled stage of the amplifier. The gain control therefore causes no audible amplitude modulation when the signal appears. The input signal is delayed and passed to the gain-controlled stage, whilst the gain-control signal is derived from the undelayed input. The delay circuit comprises an analog device such as a bucket brigade delay arrangement. The latter type can be obtained ready-made and offers a delay time between 0.5 and 1 ms.

Title: Heat engine with gas turbine output stage - has regenerative constant volume heat exchanger to reduce thermal loading
Inventor: FRANK ERWIN
IPC: F02G5/02
Filed: 1976-05-04
Abstract: The engine has two cylinders (1, 2) with reciprocating pistons (3, 4) on either side of a regenerative heat exchanger (5). Valves (7, 9, 10, 11, 12) control the flow through the unit. A valve (6) admits hot gas from the regenerator to a gas turbine and a valve (8) admits exhaust from the turbine into the regenerator. Atmosphere air drawn in is compressed in the upper cylinder. It flows through the generator and is heated before being burnt with fuel and passing to the turbine. The turbine exhaust then flows through the regenerator to be cooled. In cooling it produces a vacuum which is used to draw atmospheric air through the turbine. This gives the turbine alternate periods of subjection to hot and cold gases.
