Patent DE-19701722-A1 (DE)
Title: Method of producing decorative pattern
Inventor: LUTTERBERGER THOMAS DIPL ING
IPC: B44C5/04
Filed: 1997-01-20
Abstract: The pattern is produced by rotating perforated plates or sheets over each other. Different patterns may be formed depending on the arrangement and pitch of the perforations, the shape and size of the holes, and the shape and size of the plates. The plates are rotated over each other and provide different patterns depending on the rotational position. The plates are fixed in frames of different sizes. The rotation of the plates is either manually or electrically driven. A light source is arranged behind the plates to enhance the effect, e.g. by projecting the pattern onto a wall in a desired size and distortion. Alternatively, a mirror can be arranged behind the plates so they can be illuminated by reflecting a light source.

The dynamic loadings may be measured at spaced points along the main force transfer path within the machine, e.g. a wind-powered energy generation plant, with analysis of the detected loadings by splitting into amplitude and frequency components.
Patent DE-19713701-A1 (DE)
Title: Development of compressive residual stresses in corrosion resistant steels and superalloys
Inventor: SOLOMON HARVEY DONALD
IPC: B23K10/02
Filed: 1997-04-03
Abstract: The method concerns development of compressive residual stresses in corrosion resistant steels and superalloys on nickel basis.  It consists of producing a bath of molten metal, cooling the bath to build a metallurgical bond with adjoining solid metal, and quenching the bonded metal to the temperature of the surroundings below the melting zone of the metal through contact with a quenching medium. Also claimed are a method for repair of damage caused stress corrosion cracks, and a corresponding apparatus.
Patent DE-19720363-A1 (DE)
Inventor: HEIDE CHRISTIAN AUF DER
IPC: B41M1/40
Filed: 1997-05-15
Abstract: The tube is first printed and is then heat-shrunk into a circular shape and filled. The tube is first flat-printed symmetrically with the tube centre-line before the tube is bent into a ring. The initial printed image applied is distorted in comparison with the unfolded image. The distortion of the printed image is equal to the change in shape of the tube as a consequence of subsequent tube-shrink. A pre-print distortion factor is calculated which is related to the ring geometry and the heat-shrink characteristics of the plastics tube. The distortion factor relates to the centreline of the product in the filled ring and is positive, and is added to the longitudinal dimension of the printed image.
Patent DE-19722651-A1 (DE)
Title: Oil-pressure control system for vehicle automatic transmission
Inventor: YASUE HIDEKI
IPC: F16H61/04
Filed: 1997-05-30
Abstract: The system controls an initial oil pressure, which is selectively fed to a friction element (C1,C2,C3,B1,B2,B3) so as to activate it, depending on the load on the internal combustion engine. An oil pressure retaining device (31,32) maintains the initial oil pressure at a constant level independent of the engine load during a change. The initial oil pressure is maintained at a defined level for a defined period from the instant at which the change starts until it ends.

Patent DE-19751100-A1 (DE)
Title: Torque fluctuations suppression arrangement for combustion engine
Inventor: MINOWA TOSHIMICHI
IPC: F02B75/12
Filed: 1997-11-18
Abstract: The arrangement includes a gearing (31) for transmitting an output power of the combustion engine (1) to a drive path under control of the gear ratio. A control arrangement (46-48) controls an in-take air quantity which is supplied to a cylinder of the combustion engine executing a combustion.  A fuel supply timing control arrangement (43) controls the time of the fuel supply to the combustion chamber of the engine. An output arrangement (37, 41, 42) outputs a control signal to the air quantity control arrangement, so that the in-take air quantity is reduced, if a load exercised on the combustion engine exceeds a predetermined value. A signal output arrangement (36) outputs a torque variation suppression signal in response to the output of the control signal or a corresponding signal, to change the gear ratio of the gearing, so that the torque variations of the combustion engine are suppressed. The fuel supply control arrangement adjusts the time course of the fuel supply to the combustion cylinder in accordance with the torque variation suppression signal provided by the signal output arrangement.

Title: Bonding component discs to form digital versatile disc
Inventor: KEMPF STEFAN
IPC: G11B7/26
Filed: 1998-04-17
Abstract: A spin-off head turning on an axis (26) accepts the component discs (4, 6) forming the DVD. A suction unit holds the discs symmetrically in the head.

Patent DE-19818510-A1 (DE)
Inventor: LENFORT CHRISTOPH
IPC: H04Q7/38
Filed: 1998-04-24
Abstract: The invention relates to a method for allocating channel numbers to physical transmission channels for wireless protocol-oriented information exchange in a standardized telecommunication network, more particularly, a DECT telecommunication network, comprising at least one base station and one mobile station. By determining the physical transmission channels in a specified frequency band and by specifying a series and a sequence of channel numbers in line with the relevant standard, the base station allocates a logical channel number from amongst the series of channel numbers to one of the physical transmission channels so that the physical transmission channels can flexibly displace to another frequency area with the same numbering sequence. In addition, the base station sends the logical channel number in or for the relevant physical transmission channel, causing the base station or the mobile part to bring about a synchronization for the actually specified allocation.
