An arrangement for driving a consumer in a vehicle is suggested. The arrangement has at least two switch elements for influencing the current flow through the consumer. For each switch element, the current flowing through this switch element is monitored and evaluated for detecting a short circuit.

A device collects and discharges the splashed water thrown up by a vehicle wheel, and comprises a plurality of collection channels which are disposed side by side and spaced apart. The channels are held on the wheel arch of the vehicle in a position facing a tire tread, and collection channel openings, inclined downwards in their longitudinal direction, are each covered over by a respective recessed rebound wall on which a part of the impinging splashed water is thrown back into the associated collection channel. In order to enable greater efficiency of the device in the collection of splashed water to be achieved, the rebound walls associated with the collection channels are each, as viewed in cross-section, in the form of arcuately curved guide vanes, whereby a major part of the impinging splashed water is deflected by return flushing into the collection channel openings.

A wheel cover for catching spray water, dirt or the like, which, in its operating position, is located opposite to and at a distance from the tread periphery of the associated wheel and protrudes downwards relative to the level of the vehicle floor and which can be moved upwards into a non-operating position in which it is substantially retracted into the body of the vehicle. No complicated guide is necessary for the changeover of the wheel cover between its operating position and its non-operating position, since it is hinged on the body of the vehicle and can be pivoted to take up the non-operating position under the vehicle floor.

Cells are disclosed using doped electroconductive polymer electrodes and electrolytes of alkali metal cations and soft anions in polar organic solvents. The structure of the negative electrodes comprises layers of electroconductive polymers and ion exchange resin. Conditioning the negative electrodes is effected with AC current, the energy of the negative pulses exceeding that of the positive pulses.
摘要:
A rotary vibration damper for a shaft where the flywheel ring 1 and the hub 2 are connected by first resilient elements 3 uniformly distributed in the circumferential direction, and where second resilient elements 4 of an essentially column-like shape are provided between the first resilient elements 3. The second resilient elements are affixed at one end to the hub 2 and at the other end to the flywheel ring 1. When the rotary vibration damper does not rotate, these elements have a bend 7 in the intermediate zone which protrudes radially inward. This bend 7 can be reduced and eventually eliminated at higher speeds by centrifugal forces, thus causing the spring rigidity to increase.

Apparatus for introducing fluids into, and withdrawing fluids from, a hollow organ of the body, in particular a galibladder, for conducting litholysis, comprises a piston-type injection device having a multi-directional valve and which can be removably inserted into an operating mechanism. The injection device has a chamber located in front of its piston and serving as a settling chamber for a mixture of organ secretion and stone sludge removed with the solvent from the hollow organ. The valve is for the sequential connection of the pressure chamber to the hollow organ, to a tank for the solvent, and to a receiving vessel for fluid drawn off.
摘要:
In a filling-level indicator (12), especially for fuel tanks (10) of motor vehicles, flexural waves of the frequency (f) are fed into a sound conductor (11) via a transmitter (13). For the temperature compensation of the zero point of the filling-level indicator (12), the temperature coefficient of the modulus of elasticity (TKE) of the material of the sound conductor (11) will be at least of the order of magnitude of the negative amount of the temperature coefficient of the longitudinal extension (TKL). Furthermore, it has been shown to be especially advantageous to feed the flexural waves at a frequency f.sub.opt .apprxeq.50 kHzmm/d, (d) being the thickness of the sound conductor (11). A temperature compensation of the measuring sensitivity of the sound conductor is possible as a result of this measure. The filling-level indicator thereby supplies relatively accurate measurement values and is virtually independent of temperature influences within a wide temperature range.
