Title: IC engine pressure wave charge operation - controls exhaust branch passage dependent on engine speed and load
Inventor: MAYER ANDREAS
IPC: F02B33/42
Filed: 1990-10-29
Abstract: The pressure wave changer for an i.c. engine is operated such that charge air is delivered via a high pressure passage and supplied with high pressure exhaust gas from the engine, while a branch passage delivers part of the exhaust gas to a gas pocket. When the engine is stopped, or used in an emergency, the inlet (50) to the gas pocket (12) is held fully open by a spring, and  kept open during starting, idling, or at low load. As the load increases, it is steadily shut by a first pneumatic system, which shuts it completely under part-load, faster idling speed, and lower to half speed at full load. A second pneumatic system opens it in the top part of the part-load range and in the full load speed range. ADVANTAGE - No exhaust gas losses.

Patent DE-4112828-A1 (DE)
Inventor: SIEGLE GERT PROF DIPL PHYS DR
IPC: H05K11/02
Filed: 1991-04-19
Abstract: The proposal is for a radio receiver, especially a vehicle radio, which is capable of displaying or acoustically reproducing traffic information contained in digital signals.

Patent DE-4130045-A1 (DE)
Inventor: WALKER MICHAEL
IPC: H04M9/08
Filed: 1991-09-10
Abstract: A circuit arrangement for dynamic control of a speech communication terminal, comprising a compander function, is specified. Instead of analog circuits for dynamic expanders and compressors, use is made of a digital signal processor (DSP), which assigns on the basis of a pre-stored characteristic curve (KL) to the individual level mean values of the input signal gain factors, which are fed to the amplifier (VS) arranged in the transmitting branch of the terminal. The stored characteristic curve may be displaced in a manner dependent on a noise mean value or dependent on a reception mean value obtained from the sidetone signal, or be replaced by another characteristic line. In this case the effect of a change in gain in the transmitting branch on the sidetone signal entering via the receiving branch is compensated. In a further development, the circuits supplying the level mean values are also replaced by the digital signal processor, which uses subroutines to execute the functions assigned to these circuits. <IMAGE>
