Abstract: The actuator (2) comprises a piezoelectric actuator element (4), which is 18 connected to an adjusting element (12) for exerting an adjusting movement in the adjusting direction (14). For the transmission of a deflecting movement of the actuator element (4), a housing (6) is formed with a variable-shape displacer (8) enclosed therein. During operation, a deflecting movement of the actuator element (4) is transmitted to the displacer (8), so that the latter is deformed and, as a result of the deformation, performs a yielding movement. The housing (6) in this case forms a guide for the displacer (8), so that the yielding movement of the displacer (8) is oriented in the adjusting direction (14). The adjusting element (12) is also connected to the displacer (8), so that the yielding movement of the displacer (8) is transmitted to the adjusting element (12).

Abstract: An assembly (10) for converting mechanical work into electrical energy comprising a bending transducer (12) with a support (20) in the form of a strip and with at least one piezoelectric layer (22) attached thereto, the support (20) in the form of a strip being mounted at both ends (30) and an actuating mechanism (8, 30) being provided in such a way that, when the actuating mechanism (8, 30) is actuated, a mechanical force is exerted on the support (20) in the longitudinal direction of the support (26) and leads to arcuate bending of the bending transducer (12), and thereby to the generation of electrical energy. The assembly can be used to provide electrical energy for a counting device.

Abstract: A piezoelectric valve whose housing defines a valve chamber wherein at least one piezoelectric flexural transducer is located. The piezoelectric flexural transducer possesses a contact face, which faces a first outer wall of the valve housing. This first outer wall is in the form of a wiring support which possesses a support body consisting of plastic material, which at the outer side opposite to the valve chamber bears a wiring arrangement. The wiring arrangement is in electrical contact by way of a via extending through a cutout in the support body with the piezoelectric flexural transducer, since the via consists of an electrically conductive elastic plug, against which the at least one contact face is thrust at the inner face of the support body.

Abstract: A bearing shell for ball-and-socket joints or ball sleeve joints is provided with an inner hollow spherically designed bearing surface (3). The bearing shell has an outer cylindrically designed support surface with which the bearing shell can be inserted into a joint housing. The bearing shell has a multipart design with at least two shell parts (1, 2), which can be detachably coupled with one another by a clamping device (6, 8). The parting plane between the half shells extends in the direction of the central longitudinal axis (10) of the bearing shell.

Abstract: A movable machine part of a machine controlled by a control program is monitored with little effort. To this end, the machine parts currently being controlled by the control program are identified and counted. The machine parts actually moved by the control program are simultaneously counted. When the numbers differ from one another, a fault message and identified machine parts as possible fault sources are displayed.

Abstract: A piezoelectric bending transducer comprises a flat, electrically conductive supporting body having piezoceramic coatings on both sides. Each coating has an inner contact area facing the supporting body and an outer contact area facing away from the supporting body. The piezoceramic coatings are omitted from one end of the supporting body, which is fixed in a connector base. Each of the two coatings and the supporting body are electrically connected to a plug-in contact that includes an electrically conductive elastomer in a cavity in the connecting body. The elastomer is partially elastically deformed by a contact pin inserted thereinto. As a result of the ease with which electrical connections can thus be made to the transducers, this arrangement is particulary adapted for incorporation into a transducer module with plural transducers secured adjacent to each other in a common connector base.

Abstract: An apparatus for producing extrusions, such as optical waveguide plug prongs or sheaths with a central opening, from a deformable composition, includes a receiving body having an outlet opening and having an interior tapering conically at a predetermined first angle of conicity toward the outlet opening. A flow body is to be inserted into the interior of the receiving body. The flow body has an end portion tapering conically at a predetermined second angle of conicity. The second angle of conicity is smaller than the first angle of conicity. A retainer retains the flow body in the interior of the receiving body. The retainer is resilient in radial direction of the interior of the receiving body.
