Title: Ignition system with solid state switch and tachogenerator - has second storage module for second count producing off time of switch
Inventor: SEEGER KARL DIPL ING
IPC: F02P3/045
Filed: 1978-11-18
Abstract: The ignition system is for an IC engine which uses an electronic switch in the primary circuit of the ignition coil. The electronic switch is triggered by a signal derived from a tacho generator to provide phase triggering. There is a storage system which determines the point of trigger during the duty cycle in the primary circuit of the ignition coil. This is based on the period during which the primary current exceeds a threshold value. There is a storage system (19) for the counter signal, and also a second storage module (20) which takes over the value of the count at the start of the generator signal. The second count is forward and produces the off time for the switch. The signals from the generator are processed through logic circuits and make correction by either advancing or retarding the ignition points.

Title: Power station peak-load supply - is ensured by solid fuel gasifier with fluidised bed reactor having working temp. of over 800 degrees celsius
Inventor: PATTAS ERNST DIPL ING
IPC: F02C3/28
Filed: 1979-06-15
Abstract: Meeting variable demand on power station using gas turbines is ensured by gasification of carbon-bearing material using an oxygen-containing agent. This simplifies the problem of fast response to peak loads and avoids the chemical conversion of the product by applying a fluidised-bed reactor with a working temperature of over 800 deg.C. The reactor can be restarted quickly after being laid off for longer periods of time. The ability of rapid attainment of the working regime in the reactor is due to the holding of the solid fuel storing sufficient heat for reacting. At the same time, it prevents contacting of product gas with the oxygen-containing agent. The reactor permits low-value fuel to be converted and the contaminating sulphur is bonded chemically by feeding limestone.

Patent DE-2933010-A1 (DE)
Title: Loudspeaker protection against sustained overload - rectifies and averages audio voltage to operate warning LED and relay (NL 18.2.81)
Inventor: HOMMEL THOMAS
IPC: H02H3/04
Filed: 1979-08-16
Abstract: The audio voltage across a loudspeaker (L) is monitored by a rectifier bridge (G1) and averaged by a RC circuit (R1,R2,R3,R4,R5,C1) with suitable charge and discharge time constants. A potentiometer (R4) presets the averaged voltage above which the speaker is to be protected from overload. When this voltage exceeds a Zener (ZD) voltage, a control transistor (T2) starts to conduct and light a warning LED (LD). Further increase turns on a transistor (T1) which operates a relay (Re1) whose contact (r) opens the speaker circuit. A second contact (a) switches in a resistor (R8) to bypass the control transistor (T2) and Zener (ZD), so that the speaker stays off until the voltage is reduced to a low level. A third transistor (T3) limits the current through the Zener and control transistor (T2). Diodes (D3,4) limit the current through the relay transistor. The circuit protects the speaker against damage by sustained overload but ignores harmless short overload peaks.
