In the first switching state, only the first signal input is electrically connected to the antenna connection, and in the second switching state, only the second signal input is electrically connected to the antenna connection. To prevent a connected transmission devices from diagnosing decoupling from the antenna connection as a fault, in at least the second switching state the changeover device electrically connects the signal input that is decoupled from the antenna connection to a terminating device which emulates an antenna at the signal input that is connected to the terminating device.

Abstract: An accessory unit of a vacuum cleaner, alone, with a vacuum cleaner conduit, and with a vacuum cleaner. The accessory unit has a housing, a first tool end, and a second tool end for releasable connection to a vacuum cleaner conduit. The first tool end has a first nozzle for vacuum cleaning, and the second tool end has two pivotable arms for forming second and third nozzles. Each arm has distal and proximal ends. The distal ends are arranged to be brought together for forming the second nozzle, and to be spread apart for forming the third nozzle. Furthermore, the arms are folded together to bring the distal arm ends in vicinity of each other for releasable connection of the second tool end to the vacuum cleaner conduit by at least partial insertion into said vacuum cleaner conduit.

Abstract: This invention relates to a telescopic vacuum cleaner tube comprising a first inner tube, a second inner tube, and an outer tube, wherein the first and second inner tubes are arranged to form first and second telescopic links relative to first and second end portions of the outer tube, respectively. The outer tube forms the intermediate tube of the three-part tube while at the same time being fully accessible in any position, whereby one common grip for operating both of the two respective telescopic links, formed by the first and second inner tubes and the intermediate outer tube, of the three part telescopic tube is obtained.

Abstract: In installations including fixed and mobile structural elements and a rotary current motor as a drive, the rotary current motor can be used for the wireless transmission of both energy and/or data. The transmission from the fixed structural elements to the mobile structural elements of the rotary current motor is especially inductive. In the corresponding device including a rotary current motor including a stator and a secondary element, the secondary element is not embodied as a solid conductor with or without a laminated core, according to prior art, but rather as a laminated core including integrated windings which is the same as, or similar to, the stator.

Abstract: The invention relates to an electrically variable spring/mass vibrating force coupler with variable damping, electrically adjustable spring characteristic curves and electrically adjustable, variable natural frequencies using electro-rheological or magneto-rheological fluids in its coupling elements to couple masses and springs

Abstract: The invention relates to a controllable adjustment and damping device comprising at least one pressure chamber (4) filled with hydraulic fluid, a fluid container (11), a pump (5) connecting the pressure chamber to the fluid container, a compensating volume (8) and a return line (13) with a passthrough valve (7). An electro-rheological fluid or magneto-rheological fluid is used as a hydraulic fluid (6) which exerts pressure upon a piston (3) that juts out into the pressure chamber or on a membrane (17), the intensity thereof being controlled by the passthrough valve.

Abstract: A valve (1) on the basis of electrorheological and/or magnetorheological fluids includes a fluid inlet channel (3) connected through a valve gap (5) to a fluid outlet channel (4). The valve gap is filled with an electrorheological and/or magnetorheological fluid and is bounded by bounding surfaces that are embodied as electrically energizable capacitor electrodes and/or coil arrangements, whereby the field excitation thereof acts on the fluid flowing through the valve gap. At least one bounding surface of the valve gap is embodied to be movable selectively toward and away from another bounding surface, so as to superimpose a squeeze mode and a flow mode of the electrorheological and/or magnetorheological effect. The valve gap may define a meandering or spiral flow path for the fluid. In this manner, a compact valve can provide high blocking pressures and high through-flow rates.

Abstract: A hydraulic displacement machine that can operate as a pump or a motor in connection with an electrorheologic or magnetorheologic fluid includes a housing, a rotary piston arranged to rotate within a chamber in the housing, at least one displacement vane provided on the rotary piston, a plurality of field generating elements such as capacitor plate segments and/or coil arrangements that are each individually electrically energizable and that are arranged on the two sidewalls of the housing chamber distributed around the circumferential direction, and an actuator connected to each field generating element so as to move the elements of each pair selectively closer together and farther apart from each other. By applying an appropriate electric or magnetic field to the electrorheologic or magnetorheologic fluid between the field generating elements, the fluid is locally solidified in the "flow mode" to form a stationary seal plug within each fluid chamber between respective consecutive vanes.

Abstract: This invention relates to a controllable clutch based on electrorheological or magnetorheological liquids, in which the transmission of force or the transmission of torque is achieved in that an electrorheological or magnetorheological liquid is pushed through an electrode gap or magnet gap of the clutch by means of a surface acting as a piston.

Abstract: The ultimate tensile strength of a test sample is tested in a high speed testing machine having a frame (2), a force measuring device (9A), and a load application mechanism (3, 4) for applying a loading stroke to the test sample after a loading piston has passed through a lead stroke to attain the required testing velocity. A force locking, frictionally effective clamping mechanism clamps the test sample for coupling to the machine frame (2) and/or to the load application mechanism (3) when the loading piston has reached the testing velocity.

Abstract: A clamping or chucking tool for clamping a test sample in a testing machine has a clamping housing for applying a wedging action to the sample with the aid of one or two clamping jaws that are activated by an operating member that is inserted into the clamping housing and axially displaceable in the clamping housing. The clamping jaws are slidingly guided in a V-groove of the operating member but are stationary in the axial direction of the clamping housing, while the operating member is movable axially relative to the clamping housing for imparting to the clamping jaws a radial movement component perpendicularly to the longitudinal axis of the test sample. Lateral guide arms engage respective guide grooves in the clamping jaws to hold the clamping jaws against axial movement while permitting the radial movement. The clamping housing and the operating member are provided with at least one lateral opening for a rapid insertion of the test sample laterally into the clamping housing.
