Title: Pulsating deuterium-lithium nuclear reactor - has plasma surrounded by magnetic field in duct formed by condenser discharge
Inventor: FISCHER ALBERT GEORGE PROF DR
IPC: H05H1/04
Filed: 1974-01-22
Abstract: A pulsating nuclear reactor produces electrical energy by combustion of light atomic nuclei, especially deuterium and lithium, to give helium; the nuclear reaction plasma is produced by the discharge pulse of a condenser through a material consisting principally of lithium deuteride, which may be enriched with lithium 6 and tritium. Pref. an alternating current is used to produce a highly conducting current path through melted 6LiD1-xTx (where x is 0 - 1) for each successive condenser discharge; the negative temperature coefficient of resistance of the conducting liquid causes a very constricted current path in the form of a filament. In the duct thus formed, the materials are transformed into a plasma surrounded by the current; as the current reaches its peak intensity the plasma contracts suddenly inwards, so that the charged nuclei are forced inwards, striking one another and producing neutrons. These neutrons then produce the start of propagating and diverging fission-fusion chain reactions. The molten lithium deuteride constitutes a self-renewing wall for the nuclear explosion chamber, which absorbs nuclear energy and produces tritium by fission of lithium-6.

Patent DE-2406974-A1 (DE)
Title: Air cooled condenser for steam power stations - has thin walled plastic tubes for steam and condense flow
Inventor: VOLLHARDT FROHMUT
IPC: F28F1/00
Filed: 1974-02-14
Abstract: The condenser has a metal, steam entry header and a metal condensate return header running parallel to the steam header. Between them runs a series of plastic tubes with gaps between them so that cooling air can flow past them and remove heat by transfer through the walls of the tubes. The tubes are made of plastic less than 100 microns thick. This is possible because the condenser works at low pressure and in turn achieves an adequate rate of heat transfer in spite of the nature of the material. The construction is cheaper and more asily repaired than conventional metal tube condensers. The tubes can vary in thickness along their length and can be supported on wire mesh.
