Title: Fuel gas prodn. from fossil fuels - in a gasifier combined with electrolysis of water
Inventor: SCHUELLER KARL-HEINZ
IPC: C10J3/00
Filed: 1977-02-25
Abstract: Prodn. of fuel gas (esp. high-Btu gas) comprises (a) gasifying solid and/or liq. fossil fuels with O2 produced by electolysis of H2O, and (b) mixing the prduct gas with the electrolytically produced H2. The waste heat from the process can be converted into electrical energy in a thermal power station, which can also be fuelled with part of the product gas. Addn. of electrolytic H2 reduces by 1/3 the amt. of fossil fuel required to produce a gas with a given CH4 content (after shift conversion and methanation), effective use is made of by-produced O2.

Title: DC traction control for underwater craft - has electronic switching and emergency stop with control resistances connected to motor
Inventor: ANGERMAIER PETER ING GRAD
IPC: B60L50/11
Filed: 1977-03-15

Title: Solar energy converter with array of lenses - heats stainless steel heat exchanger containing fluid, and tracks sun
Inventor: JOHN HANS-GUENTHER
IPC: F24S23/30
Filed: 1977-03-24
Abstract: The arrangement for converting solar energy into thermal energy uses either gas or liquid. It can be used directly for heating air. If for example oil is used as heat exchange medium then a thermostat controls oil temperature. The solar energy collector has array of several side by side arranged lenses. The heat exchanger is arranged at the focal points of the lenses. A liquid or gaseous medium flows through the heat exchanger. Mineral oil can be used as such a medium and the heat exchanger is made from stainless steel. The assembly of lenses and heat exchanger is orientated by a motorised drive whose actuator is energised by solar energy.

Title: Fish feeding stuff - with sludge from biological effluent treatment replacing part or whole
Inventor: STAEHLER THEO
IPC: A23K10/37
Filed: 1977-05-07
Abstract: Animal feeding stuff, esp. for fish but also suitable for mink, consists wholly or partly of thickened sludge. This is available from biological treatment plants for the waste water from piscicultural establishments, from stables of animal farms, breweries or yeast factories. This replaced a part of the conventional fishmeal which is becoming more rare and saves the import of albumin carriers such as soy beans. The resulting mix is easily digestible, as the sluge contains 30-40% albumin.

Title: Solid electrolyte cell for measuring oxygen activity in steel melt - uses oxidic chromium-aluminium cermet as standard solid
Inventor: FISCHER WILHELM ANTON PROF DR
IPC: G01N27/411
Filed: 1978-05-03
Abstract: Solid electrolyte cell is used for correction-free measurement of low oxygen activities in steel melts, in which the cell is immersed, by comparison with a standard solid of known oxygen activity surrounded by a solid mixed oxide electrolyte, which conducts oxygen ions but has negligible electronic conductivity at relatively high temps. The novel feature is that the standard solid consists of oxidic mixed crystals, one oxide component (I) of which is an ordinary material for the prodn. of standard substances, whilst the other oxide component (II) has a lower O2 partial pressure, and the mixed crystals of the metal components. The standard solid has an O2 partial pressure in the 10-15 to 10-12 range, as required for the determn. of oxygen activities under 50 ppm in the melt.

Title: Rotating scanner for ocean bed - balances scanning movement by dependence on rotation of reception optics
Inventor: KUPER GERHARD DR ING
IPC: G02B5/04

Title: HV low loss transmission cable - has transmission cross-section of multiple layers of conducting and insulating material
Inventor: HAAG ERNST WILLI DR
IPC: H01B9/04
Filed: 1979-04-20
Abstract: H. V. cable for transmission of a.c. or d.c. voltages is designed to operate at a high level but with low losses. The cable is of circular cross-section and consists of annular rings of conducting layers that are separated by rings of insulating material. Voltage increases from the inner core to outer layer.
