Patent DE-2401535-A1 (DE)
Title: Fuel injection with stroboscope timing - injection pressure is sensed and activates strobe lamp to give accurate measure of start of injection
Inventor: GRUPP EBERHARD
IPC: F02M65/00
Filed: 1974-01-14
Abstract: A fuel injector utilises a needle and orifice to control fuel supply rate. Fuel is supplied to the nozzle chamber through a channel from the inlet pipe. The stroke of the needle is governed by a shoulder that locates against a step in the housing. When the pressurised fuel supply is commenced the needle lifts off the seat against the resisting force of a coil spring. Upwards movement of the needle results in fluid pressure being transmitted from the top chamber to a pressure sensor. The sensor generates an electrical signal to an amplifier coupled to a stroboscope. The stroboscope beam is directed onto a timing disc coupled to the engine crankshaft, with a marker. The arrangement permits the start of fuel injection to be closely monitored. A second connection allows connection of a second pressure injection chamber.

Title: Fault location of electronic data processing system - using functional units connected to common central line system
Inventor: HAEFNER RAIMUND
IPC: G06F11/07
Filed: 1974-03-30
Abstract: In order to distinguish the functional units, the line system contains address lines, and the line system transmission paths are to a large degree secured by check bits. In the event of a fault, the change-over devices are influenced by a monitoring element which tests the accuracy of information in the line system. Consequently, the typical address in the line system at this moment for the functional unit, which triggers the fault, is directly transferred by the change-over devices for output to a functional unit, which is used for other purposes in the case where no fault has arisen.

Title: Microwave pumped light detector - designed for optical signal demodulation with reduced noise from photoconductor in microwave resonator
Inventor: MUELLER RUDOLF PROF DR
IPC: H01L31/00
Filed: 1974-09-04
Abstract: A microwave resonator contains a light-sensitive microwave reactance which controls the resonator frequency as a function of the incident light to produce light-dependent microwave reflection. The light-sensitive reactance is pref. a free-wheeling psn-diode.
