Title: Small heating furnace operating by decomposition of water - for iron and steel works, power stations, district heating and factories
IPC: C01B3/04
Filed: 1974-12-05
Abstract: Small heating furnace made of material resistant to very high temps. is introduced into a large furnace and has several apertures for release of extreme heat, thus reducing the initial heat by applying it to the production of steam or hot water. Acetylene, O2 or similar materials are used initially to obtain a very high temp.; when this is reached, minimal quantities of water are injected into the superheated small furnace causing decomposition of water into O2 and H2, and causing several explosions. Pre-heating is then terminated, to provide continuous heating due to the repeated explosions caused by the decomposition of water. At the beginning of injection, one may use water mixed with methanol, alcohol or similar substances.

Title: Semiconductor diode stack for use with contactors - uses sprung spacing and contacting elements holding diodes firmly in place
IPC: H01L23/40
Filed: 1975-09-12
Abstract: A semiconductor diode stack is mounted in parallel with the switch elements of an electrical contactor system. The diodes, the number of which is controlled by the operating voltage, draw a low level short duration current, the design allowing cooling and some mechanical flexibility. Each diode (36) is disc shaped with an isolating peripheral ring. Connection between diodes is by a basically 'U' shaped metal element (50). There are two sprung elliptical wings (54) folded over the top of the 'U' and extending from the base of the 'U' in the plane at right angles to the vertical elements. Pressure applied between the stack ends forces the wings down until the diodes are seated squarely onto the upper and the lower faces of the 'U' element.
