Title: Resetting system for motor vehicle directional indicator signal switch
Inventor: TILLMANN ULRICH
IPC: B60Q1/40
Filed: 1995-09-14
Abstract: A resetting system for a turn-signal switch in a car uses electronic units to store the switch-on condition and automatic resetting of this. The reset device is connected to a first sensor evaluating the steering wheel direction of rotation and its neutral position. In addition, the sensor (4) evaluates the steering wheel angle. The reset device (3) is connected with at least one additional sensor (5,6) evaluating a car parameter. In fact, the additional sensor are front wheel sensors linked to the car's ABS system. The first sensor allows the rate of change of steering wheel angle to be calculated. It uses a potentiometer.
Patent DE-19534286-A1 (DE)
Inventor: HAGENAUER OTTO ING
IPC: F02M63/00
Filed: 1995-09-15
Abstract: In a fuel-injection pump wherein a piston (7) reciprocates in a cylinder bore (5) of a liner (3) having an annular lubrication groove (27), the groove is filled with lubricating oil through a supply duct (29) and is emptied, in a cyclic manner, during a portion of the pump piston stroke, via at least one recess (35) in the piston (7), the recess being opened when it passes the end edge (37) of the cylinder bore (5). In order to prevent the lubricating oil from flowing off in an uncontrolled manner into a spring chamber (22) into which the liner (3) protrudes, while effecting a continuous exchange of lubricating oil in the oil groove (27), the axial extent of the recess (35) is smaller than the distance between the annular groove (27) and the edge (37). Thus each recess fills with oil when it overlaps the groove (27) and empties when it passes beyond the edge (37). A groove (23) and a return bore (25) are provided for returning fuel which leaks past the piston. A further annular groove (31) between the grooves (23,27) is arranged to collect residual leakage of fuel and lubricating oil.

Title: Coffee etc. pot for one-time or continued use
Inventor: UNGER RALPH GUENTER
IPC: A47G19/14
Filed: 1995-11-19
Abstract: A troughed extension (1) below the can or pot spout is bent up and outwards to its free end, the sides of the extension being continued up the pot from the extension mounting on the pot wall and possibly also bent up towards one another at the crown. The two sides and the end wall at the free end (2) of the extension should be relatively higher.

Patent DE-19606154-A1 (DE)
Title: Circuit for measuring dia. of metal bodies esp. wires
Inventor: SPANGENBERG ROBERT
IPC: G01B7/12
Filed: 1996-02-20
Abstract: The circuit has a first device (1) which generates a sensor signal and an oscillator (O) which feeds electrical signals of a definable frequency to the first device. A second device (2) generates a reference signal depending on the ambient temp. and/or humidity. A third device (3) combines the sensor and reference signals to produce an output signal representing the variation in the metal body dia. The first and second devices are arranged so that both are exposed to the same ambient temp. and/or humidity. The effects of the ambient temp. and/or humidity are therefore compensated for when forming the output signal. The reference signal can be generated at different times during the measurement of the dia. variations.

Title: Solenoid actuated seat valve
Inventor: MEYER KARL-JOSEF
IPC: F16K31/06
Filed: 1996-06-25
Abstract: The solenoid driven valve has a needle-shaped sealing element (15) whose pointed end locates in the seal (14) and with a widened head (20) at the rear. The head and the pin have a loose fit inside the stepped bore of the solenoid driver (18) to allow the pointed end to self centre in the seal. The stepped bore open the valve by pulling the widened head against spring pressure. The widened head is linked to the closing spring (27) by a ball bearing (25) thrust coupling. This provides sufficient lateral flexibility to enable the valve element to self centre.

Title: Removal of solid pollutants in a gas duct
Inventor: SCHMIDT KARL-HEINZ DIPL ING
IPC: B08B5/04
Filed: 1996-11-07
Abstract: Removal of soot or dust deposits in a duct involves providing suction heads at the inlet and outlet of the duct. The positions of the suction heads can be changed. Also claimed is the equipment used in this method.  Suction heads at inlet and outlet may move independently or synchronously at the same or at different pressures. Items in the duct, for which this system was particularly designed, are honeycomb or plate catalysts or heat exchangers. A controller moves the suction heads in a two-dimensional co-ordinate path.
