IPC: G01R31/36
Filed: 1971-05-04
Abstract: 1342110 Automatic current control H K SCHOLL 23 April 1971 11116/71 Heading G3R [Also in Divisions G1 and G4] The discharge current of a battery (22) Fig. 6 (not shown) is maintained constant by a servosystem which includes a motor (57) for adjusting a rheostat (41) in the discharge current path. Signals respectively proportional to the desired and actual currents are compared in a differential amplifier 113, and if their difference is too great one or other of two Zener diodes 117, 118 breaks down to energise a corresponding relay R5 or R6 which in turn supplies power to the motor to drive it in the appropriate direction. The presence of the Zener diodes prevents hunting, and a storage capacitor 119 across the differential amplifier output provides damping.

Patent DE-2214024-A1 (DE)
Title: Exhaust gas antipollution system - recycles most engine exhaust gases after addition of oxygen and fuel in closed loop
Inventor: EBERLE RUDOLF
IPC: F02B47/08
Filed: 1972-03-23
Abstract: Air pollution by exhaust gases of internal combustion engines is largely eliminated by discharging only a small part downstream of a cooler and of an activated carbon filter to atmosphere or into a closed container. The greater part is recirculated in a closed loop to the engine after oxygen has been added to it from an oxygen cylinder, and fuel. The oxygen feed valve is controlled by an oxygen meter which also receives a control signal depending on the engine load. This burns the hydrocarbons and the carbon monoxide, still contained in the exhaust gases, in the engine itself and results in lower total amounts of pollutants emitted into the atmosphere.

Title: Mould for mfr of ceramic or plastic parts with small holes - is built up from plates with semi circular grooves
Inventor: SCHMIDT HELMUT
IPC: B23P15/16
Filed: 1973-12-14
Abstract: Holes of very small bore in moulded ceramic or plastics parts are obtained with the aid of pins which are supported in plate assemblies at either side of the mould. As the support holes for these pins are too small to be drilled in the thick mould plates, the holes are formed by placing together plates in which semi-circular grooves have been ground at the required pitch distance. when the plates are placed together, the semi-circular grooves form the support holes for the pins. The pins used are provided with a head at one end and a point at the other. The heads are clamped between two mounting plates, comprising a top mounting plate against which the pin heads lie and a bottom mounting plate with holes small enough to prevent the pin heads passing through. Accurate positioning of the pins is achieved.
