Title: Shut-off valve for especially gas and oil pipe which is to be closed down in sections
Inventor: MERTSCH JOACHIM DIPL ING
IPC: F16K5/20
Filed: 1996-09-16
Abstract: A pipe (18) shut-off valve (10) has a housing (16) with pressure chambers (17) which is closed by a barrier (11) surrounded by a ring seal (12) against the housing. The ring seal end-faces (26,27) are of different diameter. When the barrier and seal are operated the pressure exerted on the seal end-faces can be increased or reduced by a pressure regulation valve (20) operating through hoses (21,22,23) as selected. Each pressure hoses are fitted with a by-pass hose (31,32) circumventing the pressure control valve. Non-return valves are fitted to the pressure hoses (21,22) and by-pass hoses on both sides of the pressure regulation valve.

Abstract: The bath carrier is of hard foam material, and includes a self-adjusting base, with an opening (3), in the base (1) of the carrier, having tapering edges (3a,3b) with a flat surface. An insert (5) fits into the opening, with a matching cone shape to fit the tapered edges, and with a lateral dimension which can be varied at right angles to the longitudinal base axis. In the upper locked setting of the insert, it floats over the opening and its lateral dimension is brought to its lowest value.

Patent DE-19712700-A1 (DE)
Title: Valve for high performance four-stroke reciprocating piston engine
IPC: F01L3/20
Filed: 1997-03-26
Abstract: The valve has an elliptical head supporting two parallel stems which run in parallel bores in a common valve guide. The valve seat angle can vary around the periphery, e.g. from a maximum at the major axis, to a minimum at the minor axis.  The seat angles are chosen to suit the geometry and materials of the valve and seat. When the coefficient of thermal expansion of the valve material is greater than that of conventional cast-iron guides, the valve head can have a stiffening web, which lies along the major axis on the stem side of the head, to minimise thermal distortion of the head.

Title: Wiping device, especially for cleaning windshield of car
Inventor: KLUG HANS-GEORG
IPC: B60S1/08
Filed: 1998-06-20
Abstract: A wiping device, especially for cleaning a windshield of a car, has at least one wiper driven by an electric motor and able to be displaced between two end positions. There is a control unit which processes as input parameters the output signals of a rain sensor plus the switching signals of a manually operable switch device. It controls a supply voltage of the electric motor and thereby the wiper speed as output parameters. The wiper(s) can be driven with variable wiper speeds and variable interval pause times according to a rain amount determined by the rain sensor (12). With a minimal rain amount, the wiper(s) run(s) with much less speed than a rated speed in an interval mode and the interval pause times become shorter with increasing rain quantity.
