Title: Anode combustion plant - with suction pipe for extracting powder fill
Inventor: WINTER BASTIAN DE
IPC: C25C7/02
Filed: 1972-10-13
Abstract: A suction device for anode combustion plant is used for removing pulverised filler, e.g. anthracite or coke, from the cells, in which this filler surrounds the elongated anode during the combustion process. The suction device comprises a pipe lowered by an overhead crane into the gap between the cell wall and the anode within the cell. The suction pipe is fitted with a revolving joint permitting the nozzle at the end of the pipe to rotate about the axis of the pipe while it is being lowered into the cell; further rotation is also caused while it raised out of the cell again. The nozzle is thus rotated at each lifting and lowering by a predetermined angular amount. This enables the elongated nozzle to be oriented in correct position automatically each time it is lowered into the narrow gap between the elongated anode and the surrounding cell wall.

Title: Pulsating deuterium-lithium nuclear power station - using block of lithium deuteride-tritide with molten core to contain plasma
Inventor: FISCHER ALBERT GEORGE PROF DR
IPC: G21B1/03
Filed: 1974-01-04
Abstract: A pulsating nuclear reactor for the prodn. of useful electric energy generates heat by burning D and Li to He. The nuclear reaction plasma is produced by rapid discharge of a concentric plate condenser along a conductivity path, preformed thermally, through molten 6LiD1-xTx (in which 0  x 1). The prim. neutrons formed by fusion in the resultant high temp., high pressure channel act as starting point of fission-fusion reaction chains, which are enclosed by the surrounding liquid walls, in which only T is produced and is then bound chemically. The shock waves, radiation and heat of reaction are absorbed by the liquid, which acts as heat transfer medium to the connected turbo-generator power station and also, where it is solidified, acts as solid contg. wall and heat buffer. The reactor is simple, cannot explode and produces no radioactive waste. Fuel supplies are plentiful.

Title: Electronic flasher control for car - with single fast flash rate generator and impulse divider for normal use
Inventor: PROHASKA HANS
IPC: B60Q11/00
Filed: 1974-03-07
Abstract: A frequency source provides a continuous series of impulses at a fast ratte, whenever the direction flashes switch is operated. A current sensitive relay operates a switching relay so that if the current drawn from the flasher unit alters, i.e. one or more flasher lamps fails, then the switching relay connects the flasher lamps directly to the flasher unit. In normal use the impulses are fed to the lamps via a frequency divided to generate a slower rate of flashing. The frequency divider can be provided by a simple flip-flop and the whole flasher circuit comprises a simple electronic unit for easy replacement.
Patent DE-2411327-A1 (DE)
Title: Blanking-signal generator for TV - produces composite standard blanking signal from sync. signal even when heavily distorted
Inventor: WILHELM RUDOLF
IPC: H04N5/067
Filed: 1974-03-09
Abstract: The blanking signal generator, for televisions, has a circuit to produce a pulse signal of double the horizontal frequency from the sync. signal and whose position and width correspond to those of the blanking signal. A horizontal-frequency blanking signal is derived from the double-horizontal-frequency pulses, and a vertical-frequency signal is derived from the sync. signal. The double-freq. pulses are counted to determine the leading and trailing edges of the vertical blanking part of the blanking signals: the count being started by the vertical signal. The vertical blanking signal is formed using the defined leading and trailing edges. The horizontal and vertical blanking signals are then added to give the standard composite blanking signal.

Title: Test equipment for fault detection - uses plug-in assemblies in telephone exchanges and has step-by-step switch
Inventor: KUESTNER MANFRED
IPC: H04Q1/20
Filed: 1974-05-31
Abstract: The switch automatically detects faults such as short-circuits, shunts and incorrect polarity of rectifiers, and displays them. Each contact pin of the tested assembly is connected to a potential through a test resistor of such value, that in case of a short-circuit and/or shunt between the pins the applied potential stops further movement of the switch. In order to detect bridges in circuits and incorrect rectifier polarity, keys are provided disconnecting certain test resistors. Light emitting diodes are connected in parallel with test resistors for faulty connection signalling. The l.e.d's are connected by a relay operation. Only those light up which correspond to the step at which the switch has been stopped.
