Patent DE-19650434-A1 (DE)
Title: High-pressure accumulator for hydraulic systems
Inventor: LEUTNER WILFRIED
IPC: F15B1/22
Filed: 1996-12-05
Abstract: Movement of the dividing piston (7) produces within the storage space (9) a subspace (13) which can be shut off from the pressure medium connection (4) and serves to hold a residual volume between connection and piston seal (10) when the accumulator is emptied. The pressure in subspace at least equals that in the gas space (8) though the effective sectional area of the subspace is smaller than that of the gas space. The subspace is shut off from the connection by means of a stationary soft seal eg. O-ring. A cylindrical extension (5) reaching inwards from the cylinder base (3) is ringed by the O-ring and is matched by an opening (11) within the dividing piston. Thus when the accumulator is emptied the piston endface contacts the O-ring ahead of the piston end point so the O-ring is compressed to shut off the subspace in conjunction with the piston endface (12), cylinder base and piston seal.

IPC: B60S3/04
Filed: 1996-12-11
Abstract: A method for cleaning vehicles comprises applying an aqueous acidic cleaning agent (A) directly before or directly after applying an aqueous alkaline cleaning agent (B) onto the dirty surface, so that the two cleaning agents come into contact with each other: the first cleaning agent is not removed (especially by rinsing with water) before the second cleaning agent is applied.
Patent DE-19700578-A1 (DE)
Title: Stationary fire extinguishing system
Inventor: GOSSEN VIKTOR
IPC: A62C35/02
Filed: 1997-01-10
Abstract: The system consists of a container which is formed as a boiler (1) linked via a line (7) to the main water line (6) and via a steam tap line (5) to a steam valve (2). When there is fire in the proximity of the system the water is boiled, producing pressure to open the valve automatically, whilst at the same time this pressure closes the water valve (8) so that the trapped steam is directed towards the fire. When the fire is extinguished, the fall in pressure closes the steam valve and accordingly re-opens the water valve. If the fire persists, the steam valve remains open until the water is exhausted so the boiler must be re-filled to repeat the steam process.

Abstract: Disclosed is a device for cooling electronic components, preferably high-performance laser diodes. The inventive device is configured as a microstructural heat sink comprising a plurality of individual layers and at least microchannel plate with a plurality of microchannels and a distribution channel. The inventive device also comprises an intermediate plate with one or several connecting channels and a collector plate with one or several collector channels. Once the microchannel plate, the intermediate plate and the collector plate are assembled along with a covering plate and a base plate for the individual layers, sealed cooling channels are formed. A cooling medium can be fed through said channels. The cooling medium is directed into the microstructural heat sink through an inlet and discharged therefrom through an outlet. The invention is characterized in that the intermediate plate for the cooling medium forms a graded and/or skewed transitional structure through which the cross section areas of the inlet and/or outlet arising from an all-layer vertical surface cut can be successively carried over into the cross section area of the microchannels arising from a vertical microplate cut in the area of the microchannels.

Patent DE-19722697-A1 (DE)
Inventor: KERZ LUDO
IPC: H04N1/00
Filed: 1997-05-30
Abstract: The invention relates to a method for digitally rasterizing a half-tone image with rasters of any width and angle. According to the invention, a threshold matrix is read out and the threshold values are compared with the colour values of the half-tone image. The threshold matrix used is a threshold matrix in which the threshold values represent one or several pixels of a raster, said raster being arranged at an angle and being used to approximate the desired raster width and the desired raster angle. Whilst the threshold values are being read out, an error between the desired raster and the raster approximated using the threshold matrix is detected and as soon as said error exceeds a predetermined limit value, said error is compensated by a correction of the readout address for the threshold matrix. Stored bit patterns can also be used as an alternative to the threshold matrix. Said bit patterns can be obtained by comparing the tone values which have to be reproduced and a threshold matrix.

Filed: 1997-11-07
Abstract: The invention relates to a distributing blower (10) for chemical substances, especially plant protectants, used in agriculture and forestry comprising two blower units (40, 42) arranged on an equipment frame. Said blower units each have a blower housing and a radial running wheel (48) which is rotationally driven around a running wheel axle by a drive mechanism, whereby the radial running wheel (48) together with the blower housing generates a blower air stream which is formed in the blower housing. After entering through a housing outlet opening, the blower air stream forms a distributing air stream for the chemical substances, said distributing air stream widening only in one total stream direction. The distributing air streams generated by the blower units (40, 42) widen in varying total stream directions. In order to improve such a distributing blower, a highly uniform distribution of the plant protectants can be obtained such that the blower air streams in the blower units have a varying direction of rotation relative to the respective running wheel axle.
