Patent DE-19653297-C1 (DE)
Title: Method of testing functional characteristics of geophysical motion detectors esp. geophones
Inventor: EDELMANN HANS A K DR
IPC: G01V1/18
Filed: 1996-12-20
Granted: 1998-02-19
Abstract: The method subjects the movement or motion detector to a mechanical excitation or stimulation. The resulting spectral characteristics are recorded and analysed. The motion detector is excited in an oscillation direction which is essentially orthogonal to the direction of movement in which the motion detector can be used to provide a measurement output. The motion detector is preferably stimulated by a force of alternating frequency. Using a computer program, resonance peaks in the frequency range and/or amplitude peaks in the time range of the tested motion detector may be derived from the recorded spectral characteristics. These peaks are correlated with a standardised spectrum. When the differences between the two exceed a limit value the resonance of the detector is considered a defect.

Title: Fuel injection priming charge regulation method for IC engines
Inventor: AUGUSTIN ULRICH DR ING
IPC: F02D41/38
Filed: 1997-01-11
Granted: 1998-04-16
Abstract: The method involves connecting the fuel injectors (1-8) of an engine to a common pressure line (9) with a pressure gauge (12), to supply fuel from a fuel pump (11). The injection period of the injectors are individually controlled with a control signal (19). The control signals are generated from a regulator (13) and are individually variable by a measuring signal. The pressure gauge generates the respective measuring signal (16) from the static pressure differential in the pressure line after an injector has been closed. A regulator (13) uses the signal to calculate the difference between the pressure in the pressure line and the nominal pressure, when an injector has been freed, and determines the injection volume extracted from the pressure line. When the volume of the injector concerned deviates from a set reference value, the regulator corrects the individual control signals (19) of the injectors, by altering the injection period for the injector.

Title: Fuel cell especially a polymer membrane fuel cell
Inventor: DOHLE HENDRIK
IPC: H01M8/1018
Filed: 1998-01-28
Granted: 1999-04-01
Abstract: Existing fuel cells with proton conducting electrolyte use a membrane made of perfluorinated plastic material as electrolyte and are powered using hydrogen or methanol as fuel. One disadvantage is that said electrolyte membrane allows both the protons and the fuel to pass through resulting in a loss in fuel cell efficiency. Migration of the fuel molecules through the electrolyte (14) from the anode side to the cathode side is prevented in such a way that the fuel cell exhibits a hydrogen permeable barrier layer composite (20) comprising two outer layers (22, 24) and a central layer (26) arranged between the latter. Each outer later is made of palladium and/or a palladium alloy and the central layer is made of niobium and/or tantalum and/or an alloy based on one of said metals. Palladium, niobium and tantalum exhibit high atomic hydrogen diffusibility but are impermeable to larger atoms and molecules. The barrier layer composite separates the anode gas space from the cathode gas space in such a way that the fuel cannot migrate through the electrolyte to the cathode side.

Title: Selector device for automatic or partially automatic gearbox in motor vehicle
Inventor: WOERNER GUENTER
IPC: F16H59/10
Filed: 1998-04-28
Granted: 1999-11-04
Abstract: The selector device includes a locking mechanism with a knuckle lever mechanism (8) connected to the selector lever (2) and a latching device (32) which can be pivotally moved by a drive device such as a solenoid (40) to engage a knee (24) of the knuckle lever mechanism to prevent it from breaking, thus preventing movement of the lever. The drive device releases the latching device, allowing movement of the lever, upon a predetermined operating condition. The selector device has a locking mechanism with a knuckle lever arrangement that has a knuckle joint (10) and first (12) and second (14) arms, the first of which is pivotally connected to a movable lever of the selector device and the second of which is pivotally fixed to a stationary axis of rotation. A latching device is rotated about an axis by positioning a drive device such as a solenoid valve so that it prevents a knee of the knuckle joint from breaking, thereby locking the selector device.  When a predetermined operating condition, e.g. operation of the brake pedal, exists the solenoid is activated/deactivated to allow the latch to pivot so as to release the knuckle joint, unlocking the selector device even if a large manual force is exerted on the lever. The locking latch may be provided with a locking gate window which provides two locking surfaces or may be replaced with a locking cog.

Title: Lavatory flush regulating system
Inventor: HALDEREN JOHN VAN
IPC: E03D1/14
Filed: 1998-06-05
Granted: 2000-02-17
Abstract: The device has a sensor unit to detect the bowl content and for automatic dosing of flush water dependent upon the content. The unit is a gas sensor (22), to recognize fecal gases. The sensor signals are processed in a control unit (24), which operates a valve (16) to supply a suitable optimum water volume for a flush to the lavatory bowl (14). A second sensor (26) determines whether the lavatory is in use and when it is left by the user, and generates a signal accordingly. The gas sensor is located on/in a suction tube (18) connected to the flushing water pipe (10).
