Patent DE-19601499-A1 (DE)
Title: Bearing pressure compensation for rotary piston engine
Inventor: KLAUS ADOLF DIPL ING
IPC: F01C11/00
Filed: 1996-01-17
Abstract: The pressure compensation is for an engine effectively comprising several systems: precompressor, compressor, combustion, afterburner, etc. The separate systems are coupled turned 180 deg. from each other, so that the adjacent combustion chambers are diametrically opposite each other. Combustion pressure thus works on the opposite sides of the runners. The bearing pressure in the runner guide casing is raised and compensated. Since the pressure ratios in the engine are not constant, the compensation is not total, but more relief is achieved and synchronous combustion cannot happen.

Title: Torque transfer system, such as clutch, control system
Inventor: FISCHER ROBERT DR
IPC: F16D48/02
Filed: 1996-01-20
Abstract: The appts. is mounted in force flow between drive machine, such as engine, and translation-variable appts., such as gearbox of vehicle, with setting member for controlled adjustment of torque transferable by torque transfer system using control unit, such as computer to control setting member in signal connection with sensors and other electronic units, such as ID units and slip ID units. The control unit detects from the data from torque, slip and operating state identification units the friction energy input into friction faces of the clutch as function of time and determines at least one temp. of clutch as function of time and compares it with threshold value. When this threshold is exceeded the control unit signals high thermal strain on the clutch and introduces protective measures, such as time variable control of clutch setting  device (11).

Title: Diamond truing and dressing procedure using known diamond dresser
Inventor: HERRBACH SIEGFRIED DR ING
IPC: B24B53/00
Filed: 1996-11-26
Abstract: To obtain the required working profile (WP) of the dressing diamond tool, one or several characteristics of the profile should be specifically modified before or after dressing and truing operations in terms of crude working depth (Rts), effective width (bd/3) and web width (S) i.e. between tool grooving. The factors modified comprise radial infeed, axial feed (fad), angle of turn (ALPHA), angle of attack (BETA) and infeed angle (GAMMA). The web width can be calculated for a constant effective width (bd/3) from the change in feed (fad). These ideal values once calculated are arranged in a first mathematical optimisation model in which the feed-dependent effective tool width is determined by means of a boundary curve (G). The surface contour of the tool is found by 3D or CCD camera and plotted in a mathematical 3-D model so as to find the required tool angles (ALPHA, BETA, GAMMA) as a function of the necessary profile curve.

Patent DE-19702271-A1 (DE)
Title: Digital data transmission method e.g. for motor vehicle safety equipment
Inventor: FENDT GUENTER DIPL ING
IPC: B60R16/02
Filed: 1997-01-23
Abstract: The method involves transmitting a synchronisation pulse stream with at least one synchronisation pulse before transmitting the data to be transmitted. The synchronisation pulse stream synchronises the data pick-up clock generator at the receiver end. The synchronisation pulse stream contains the synchronisation time point and also a clock frequency information which is determined at the receiver end. The clock frequency is adjusted according to the determined clock frequency information by the data pick-up clock generator whose clock frequency is controllable. Preferably, the time period of a synchronisation pulse may be taken from the clock frequency information which contains the clock frequency of the data pick-up clock. The time period of the synchronisation pulse preferably corresponds to the period of a data pulse.

IPC: C02F3/30
Filed: 1997-01-27
Abstract: A procedure controls nitrification and denitrification on waste water treatment plant. The redox potential (u(R)) is measured. A break point (sharp change in gradient) of the redox potential curve provides an indication of the end of the denitrification phase. In the method two or more measurements over an interval are used to calculate and store the gradient. Further such gradient evaluations are made. To switch off the denitrification phase, a first signal (S1) is generated, containing information concerning the results of comparison. Also claimed is the equipment required to execute the method described above. It preferably uses the fuzzy logic as cited, or a neural network.
