Title: Toilet flushing valve
Inventor: FRHR SCHENCK ZU SCHWEINSBERG A
IPC: E03D3/04
Filed: 1988-10-08
Abstract: Toilet flushing valves are usually operated such that the actuating knob is pressed in, until the main valve is in the fully-open position, and is then released. They discharge approximately always the same quantity of water which is necessary for flushing away solid faeces. In order to be able to trigger, as required, a smaller or a greater, predetermined quantity of water, then, in the case of a toilet flushing valve having an actuating knob which, for mechanical opening of the main valve out of a rest position, can be pressed in, counter to the force of a first compression spring, until the main valve is in the fully-opened position and can then be released, the water quantity for each flushing procedure increasing as the knob is pushed in to an increasing extent, the actuating knob is assigned a second compression spring, whose force is effective only when a predetermined part-open position of the main valve has been reached and sets an additional resistance, increased in a stepwise manner, against further pressing-in of the actuating knob. <IMAGE>

Title: Variably controlled printer with electromagnetic drive
Inventor: CHU MOSI
IPC: B41J2/295
Filed: 1989-02-28
Abstract: The subject matter of the invention is a printer for printing a dot matrix onto a piece of paper which is supported by a carrying plate. A flexible, piezoelectric laminate element is assigned along a first edge to a planar ferromagnetic element which is operatively connected to the flexible piezoelectric laminate in an area which is remote from the first edge. A dot printing element is arranged in such a way that it can be adjusted so as to experience the same movement as the flexible piezoelectric laminate. In addition, control means for producing first or second voltage signals are provided, which voltage signals excite the planar ferromagnetic element and bring about a first and a second position of the laminate. Finally, electromagnetic means are provided for applying to the planar ferromagnetic element a magnetic force which can be varied in a controlled fashion, in such a way that a force is applied only when the planar ferromagnetic element is not in its first position, the said force being sufficient to print, using the dot printing element, a dot on the recording medium, which dot is a function of the applied force.

Filed: 1989-03-13
Abstract: A description is given of a releasable connection (6) for a steering column (1) in a motor vehicle, in which an outer cylinder (5) is fastened on the steering column (1). The outer cylinder is connected releasably to an inner cylinder (7) via a ball (8). An annular body (7) serving as a sensor mass releases the connection (6) by being displaced in the direction of the vehicle deceleration after overcoming the bias of a coil spring (18), so that a pivotable latch (20) resting on the annular body (17) becomes freely movable. The latch (20) simultaneously releases a spring-biased piston (12) which is displaced with respect to the ball (8). An outer groove (30) of the piston (12) accommodates a section of the ball (8) during this movement. By this means, the connection (6) between the inner cylinder (7) and the outer cylinder (5) is released. The steering column (1) with the steering wheel (2) and the outer cylinder (5), acting as an inert mass, is displaced as a function of the acceleration with respect to the inner cylinder (7) fixed on the vehicle body. <IMAGE>
