Title: Cooling circuit for liquid-cooled internal combustion engine
Inventor: BINDER WILHELM DIPL ING
IPC: F01P7/16
Filed: 1997-07-04
Abstract: A cooling circuit for a liquid-cooled internal combustion engine has a circulating pump and a main radiator plus an additional heat exchanger. The main radiator by the intermediate connection of a thermostat is connected via flow and return lines to the engine and the heat exchanger is subjected to coolant independently of the thermostat setting. The heat exchanger is located inside the main radiator. A bypass (16) is connected in between the flow and return pipes and is assigned to the main radiator. The bypass consists of a pipe (17), a circulating pump (18) and a non-return valve (19). The bypass pump and the main pump are driven jointly.

Patent DE-19730211-A1 (DE)
Title: Wind engine or wind power generator/plant with one or more rotors
IPC: F03D1/06
Filed: 1997-07-15
Abstract: The wind engine has radially mounted rotor vanes which are able to rotate about their longitudinal axes independently of each other. The vanes automatically set themselves in the direction of the air flowing around them. The automatic setting of the vanes is caused by a mechanism similar to the action of a rudder on an aeroplane. Alternatively, it can be effected by mechanical adjusters controlled by wind vanes in front of the rotor vanes or pressure sensors on both surfaces of the rotor vanes.

Patent DE-19756999-A1 (DE)
Title: Electrostatic air filter for removal of microorganisms
Inventor: HOELTER HEINZ PROF DR
IPC: B03C3/60
Filed: 1997-12-20
Abstract: The filter is used for the purification of environmental air, and particles are collected on denatured layer. A denatured layer is defined as one that not only contains no nutrients for microorganisms, but is treated with additives to destroy them. The denatured layers are applied to the collector electrode, here the inside of a tube along whose axis the discharge electrode, as wire with virtually radial spikes, is charged > 7000 kV. A tube is chosen as the simplest shape for integration in an air duct. Three layers, strongly acidic, strongly alkaline, placed on either side of a neutral layer, form collector.  The layers are made electrically conducting by the addition of graphite or activated charcoal. Also, layers are impregnated with monoclonal antibodies or substances to counteract endotoxin or to kill fungi. Layer is best composed of individual cells, like a chessboard, with different properties in adjacent cells, so good kill rate is achieved as microorganisms pass across, and through, layers. To keep layers moist, material is impregnated with hygroscopic substance and fine aerosol is dispersed into airstream during operation. Collectors are run in series.

Inventor: BERTHOLDT HORST-OTTO
IPC: G21F9/00
Filed: 1998-04-27
Abstract: The invention relates to a method for reducing the level of radioactivity of a metal part. To this end, an oxide layer is firstly removed from the metal part by using a decontamination solution. Afterwards, an oxidizing agent which is still present is removed from the decontamination solution. As a result, a layer of the metal is removed. The remaining metal can be delivered to a common scrap yard since radionuclides are only found in the layer of the metal part located close to the surface.

Patent DE-19833761-A1 (DE)
Title: Operation of cooling cell or cooling container
Inventor: SCHWARZ JOERN
IPC: F25D16/00
Filed: 1998-07-17
Abstract: The operation provides for unhindered separation of different, heavy phases of intake latent cooling fluid over the complete container height, for the duration of the cooling process. Vertical air flow is inside cooling cell. In first phase of exchange of cooling fluid, fresh latent cooling fluid is brought from below into hollow container and in second phase fresh latent cooling fluid is brought into container from above.  The cooling cell (2) has an interior hollow wall container (1), coupled from the outside to a latent cooling fluid supply system. Container has intake and return at top and bottom of holder, with either top intake and bottom return or vice versa. Control between the functions of intake or return is performed by a multi-way valve. From the intake line, fresh latent cooling fluid with stored latent heat is taken in and fed to the multi-way valve. Multi way valve is kept in position until air, initially in container, is transported via return, pipe and value into the return flow line. Then multi way valve is switched over to position so fresh latent cooling fluid from the intake line is fed in at top of container and out again at bottom. Process continues until container is completely filled with fresh latent cooling fluid. Process is controlled over predetermined times for both phases of the filling.  Independent claims are included for a cooling device.
