Patent DE-4122016-A1 (DE)
Inventor: NIGGEMANN DETLEF
IPC: B60T8/88
Filed: 1991-07-03
Abstract: Proposed is an anti-blocking system with at least two microprocessors and at least two input/output circuits which monitor each other as well as the functioning of other components of the system. If incorrect potentials are produced within the system or if signal-transmission faults occur, the anti-blocking system is reliably switched off. In spite of the small number of components used and the low production costs which result, a very high level of safety is achieved by integrating a multiplicity of surveillance functions, particularly in the input/output circuits, as well as by virtue of the redundant design of the system.

Title: Direct chemical to electrical energy conversion - using fluid dynamo fed esp. with liq. fermented fuel, and avoids noxious emissions
Inventor: STUTE HANS-JOACHIM
IPC: H01M8/00
Filed: 1991-12-07
Abstract: Direct conversion of chemical energy (pref. from liq. fermented fuels or possibly solid fuels) into electrical energy is carried out using a fluid dynamo as the energy converter. The novelty is that the fluid dynamo consists of a cylindrical container with up to 12 closed or open metal, compact carbon and/or ceramic vessels and associated equipment (fuel lines, etc.) as combinations of electrolysis units and voltaic elements in connection with mutually orthogonal permanent magnetic and electromagnetic fields and inductive electromagnetic fields with the corresponding earth metals (Mg, Ca, Fe, etc.) in the fuel. Magnetic field rotation is caused by electron spin acting on the magnetic field, resulting in acceleration of dissociated atoms of the fermented hydrocarbons in the fuel towards respective electrodes where they give up their electron charge and accept discharge electrons and form new cpds. USE/ADVANTAGE - The process may be used to provide fuel for `cold combustion' in vehicles not fitted with catalytic converters and to provide electric power for electric cars. It avoids noxious emissions and allows electric cars to function as long as fuel is present in the fuel tank

Title: Prodn. of very fine gas bubbles from high-pressure gasified liq. - involves subjecting liq. to pressure considerably below its vapour pressure
Inventor: EICHLER DIETRICH DR
IPC: C02F1/24
Filed: 1992-03-16
Abstract: Very fine bubbles are produced from a high pressure gasified liq. using a nozzle tube (7) which encloses a smaller dia. tube (4) which has several slit nozzles (5) formed along its length. Each slit nozzle consists of two nozzles arranged in line. When the high pressure gasified liq. is admitted to the inner tube (4) it flows out through the slit nozzles (5) and generates a partial vacuum between the two nozzles of each slit nozzle (5). The absolute pressure of this partial vacuum is below the vapour pressure of the liq. so that the gas is sepd. from the liq. in the form of very small bubbles. USE/ADVANTAGE - Bubbles are used to separate solid matter from liq. in settling tanks in sewage treatment plant. Gasified liq. is also used to pump sewage.
