The invention relates to a windshield wiper device, particularly for a motor vehicle, comprising at least one wiper shaft (10). Prior art windshield wiper devices having predetermined breaking points exist in order to meet the high demands of pedestrian impact protection. However, the risk of these predetermined breaking points rupturing during the operation of the wiper exists in this type of windshield wiper device. In addition it cannot be guaranteed that the predetermined breaking point ruptures in the event of a pedestrian impact. Therefore, in the inventive windshield wiper device, the at least one wiper shaft (10) can be displaced under the action of a force.

The invention relates to a driving mechanism (11) for the traction-exerting component (13) of a conveyor device (1), with a frame (10); at least one reversing wheel (15a, 15b) and one driving wheel (17) supported on said frame; an endlessly revolving, flexible traction-exerting component (13) guided around the reversing and driving wheels (15a, 15b; 17) and having a pulled strand and a returning strand; a tensioning device (18); as well as a setting device comprising the tensioning device. The tensioning device (18) has two support bodies arranged one behind the other in the direction of revolution of the traction-exerting component (13), said support bodies being adjustable against one another, and tensioning elements each supported on said support bodies. With its pulled strand, the traction-exerting component (13) is guided around one of the tensioning elements, and with its returning strand around the other tensioning element, as well as around the reversing and driving wheels (15a, 15b; 17), whereby tensioning forces directed against each other are admitted to the tensioning elements, which are arranged spaced from each other; and whereby the spacing is adjustable to a limited extent via the at least one setting element.

A compact, energy-efficient extensible illumination source combines the reliability advantages of light emitting diodes (LEDs) with the brightness of conventional lighting. High reliability of the LEDs provides trouble-free operation over a long hour lifetime. This high-output light source can be used in direct lighting applications or for backlighting for translucent materials. The illumination source includes LED printed wire board segments that may be configured to form a light line of any length. The segments are mounted on a inner mounting base which also serves as a first stage heat sink for the LEDs. The illumination source includes a linear mirror for reflecting radiant energy away from the LEDs to produce a uniform linear illumination pattern. A window provides mechanical protection for the LEDs and may be used for diffusing or filtering light from the LEDs. An integral base in contact with the inner mounting base also serves as a heat sink and provides structural support for the illumination source. The integral base further includes channels and cavities for cooling the illumination source and for housing power cables.

A unit for shielding a transponder includes at least a chip and an antenna structure with application-specific spatial dimensions and which is secured to an electrically conductive surface. The unit includes a film having formed thereon or therein a highly permeable material at least in an area having the spatial dimensions of the antenna structure of the transponder. The highly permeable material is subdivided into elongate shielding elements and free spaces arranged between the respective shielding elements such that when the substrate has been attached to the transponder, the shielding elements will be oriented parallel to a magnetic field induced in the antenna structure of the transponder, so as to suppress eddy currents which are generated by the electrically conductive surface in the antenna structure, when the transponder is being introduced in a magnetic field of a respective reading device.

A transmission with a drive side and an output side conical disk pair. One conical disk pair includes a fixed disk carried by a shaft, a movable disk non-rotatably connected with and axially movable relative to the shaft, and a support ring axially attached to the shaft adjacent a back side of the movable disk. A pressure chamber between the support ring and the back side of the movable disk is supplied with hydraulic pressure medium through a passage in the shaft that opens to the surface of the shaft. An end region of the movable disk when moved along the shaft passes over the opening at a maximum spacing of the movable disk from the fixed disk, and a hydraulic medium connection exists between the passage and the pressure chamber through drainage slots between an inner surface of the movable disk and the peripheral surface of the shaft.

A positioning device for a hand-held setting tool (10) having an actuation switch (13) for actuating the setting tool (10), with the positioning device including a rod-shaped holder (21); a connection element (22) for the setting tool (10) arranged at an end of the holder (21), and an actuating switching device including an actuation element (24), a switching link (30) connecting an actuation element (24) to the actuation switch (13), and a safety device (40) for preventing actuation of the actuation switch (13) and having a gravity-controlled intermediate element (41) having an actuation position in which it is positioned between first controlling element (34) and second control element (35) of the switching link (30), and an interruption position (16) in which it interrupts the switching link (30).

A delivery device for a sheet-processing machine, comprises at least one deposition station and a conveyer station, by the use of which, upstream-processed sheets of printed material can be picked up in a transfer location, and can be conveyed through the deposition station via a first conveying system, where they can be deposited optionally to form a stack, or can be conveyed beyond that stack. A holding device, which holds down the uppermost sheet of the stack during the transfer of a sheet to be conveyed against an entrainment or a lifting, is provided with one or with a plurality of holding assemblies which are spaced apart from each other transversely to the transport direction. A sheet-guiding element may be provided, which adjoins the deposition station and which is variable in its vertical position with at least its upstream end by the use of an actuating drive.
