Patent DE-2432802-A1 (DE)
Title: Electricity produced electrochemically from environmental heat - by decomposition and recombination cells with natural circulation
Inventor: HOEGE HELLMUT DIPL ING
IPC: H01M8/18
Filed: 1974-07-08
Abstract: The parent patent describes a method for converting heat into electrical energy, in which an aqueous electrolytic compound is electrochemically broken down in a decomposition cell at a decomposition voltage which at the reaction temperature is less than the recombination voltage and less than 1.23 volts, this decomposition giving rise to two substances, one of which is a gas; these two substances are conducted to a recombination cell and recombined to give an aqueous compound while generating direct current; this compound is recycled to the decomposition cell; the cooling process which occurs in the decomposition cell results in an inflow of surrounding heat from the environment. In the patent of addition, the recycling of the electrolyte from the recombination cell into the decomposition cell takes place automatically, as a consequence of a higher electrolyte surface level maintained in the decomposition cell than the level in the recombination cell; this difference is produced by the gas released in the decomposition.

Title: Adjustable blade kitchen knife - can be adjusted to cut food into slices of predetermined thickness
Inventor: STARMAN MARTIN
IPC: B26B3/03
Filed: 1974-09-23
Abstract: The knife consists of a handle with a blade with a serrated edge. The blade is provided with threaded studs at each end which fit into clearance holes in the handle on either side of a slot. A knurled nut is held in the slot and screwed on to the stud as the studs are pushed through the clearance holes. The spacing of the nut is such that it fits closely in the slot so providing control over the gap between the blade and the edge of the handle. This gap determines the thickness of the slice.

Title: Flashlight gas discharge lamp - with duration of flash controlled by an electronic circuit
Inventor: OKUNO KENO
IPC: H02M1/06
Filed: 1975-03-26
Abstract: A specified time after beginning of the discharge an extinguishing signal is applied to the lamp, determining the lamp burning time. A blocking current is applied to a thyristor in series with the lamp. Its control electrode is controlled by a blocking voltage circuit which blocks the thyristor and stops the lamp discharge. A delay line generates a discharge current blocking signal on reception of an extinguishing signal. At the same time, the blocking voltage circuit applies a blocking voltage to the thyristor control electrode, and the blocking current discharge circuit is switched on by the delay line blocking signal, so that the thyristor receives the blocking current.

Patent DE-2605960-A1 (DE)
Title: Oil flow guide member for oil-cooled electrical equipment - has wedge-formed tongue to produce equal oil flow in all radial flow channels
Inventor: CARLSSON TAGE DIPL ING
IPC: H01F27/32
Filed: 1976-02-14
Abstract: The guide member has a downwardly-directed wedge-formed tongue, the side of which facing away from the winding makes good contact with the surface of the insulating cylinder facing the winding. The other surface of the tongue, the surface facing the winding, will have a downwardly increasing distance from the winding. This causes the upwardly-directed oil flow between the winding and the insulating cylinder to have an increasingly more narrow flow path during its upward movement. The oil flow is therefore forced to move partly in a radial direction in between the discs or the layers in the winding.
