  • Publication number: 20080210780
    Abstract: A cleaning device (1) for a lens (2) of a headlight of a motor vehicle has two telescoping tubes (6, 7), the outer tube (6) holding a spray nozzle (9). The outer tube (6) is also surrounded by a protective tube (8) to be fixed in the motor vehicle. When the outer tube (6) is pulled out (9), the spray nozzle is displaced over the lens (2). The connections of the tubes (6, 7) are reliably protected from dirt accumulation.

  • Publication number: 20080055924
    Abstract: An illumination system for producing light and for launching the light into a proximal end of an optical cable of an observation apparatus for endoscopy or microscopy has a light source having at least one LED. In addition, the illumination system has an optical light guiding element between the light source and the proximal end of the optical cable for introducing the light emitted by the light source into the proximal end of the optical cable, wherein a first end region of the optical light guiding element on a side facing the light source has a smaller cross-sectional area than a second end region of the optical light guiding element on a side facing the proximal end of the optical cable. Furthermore, the illumination system has a cooling apparatus which has at least one cooling body and which is thermally conductively connected to the light source in order to remove heat produced by the light source from the illumination system.

  • Publication number: 20060208485
    Abstract: The connection element includes a tubular coupling which is connected on the inside at one end to a hose which has, on its side facing away from the hose , at least one clearance, of which the lateral edges running parallel to the longitudinal axis of the tubular coupling run, in the cross section of the respective clearance, so as to widen conically with respect to one another from the inside outward. The tubular coupling has at the other end, on the outside, at least one first projection which bears against one end face of a snap ring which is arranged between the at least one projection and the one end of the coupling, around the coupling on the outside.

  • Patent number: 7100950
    Abstract: The connecting element for transporting gaseous, liquid or solid substances include a tubular coupling which has on the inside a cylindrically running first recess, in which a corrugated tube is arranged, and which has a cylindrically running second recess which adjoins the first recess and In which an annular seal is arranged adjacent to the first recess and an expanding ring is arranged adjacent to the annular seal. The expanding ring has, on the outside, a first projection which points toward the coupling and engages in an encircling groove arranged in the second recess. With its projection which points toward the corrugated tube, both the expanding ring and the annular seal are in each case in engagement with the corrugated tube from outside. The subject matter of the invention is also the use of the connecting element as a subassembly in windshield washer units.

  • Patent number: 6467701
    Abstract: A shield cleaning system has a fluidic nozzle body (5) which is connected to a nipple (1) for the supply of cleaning fluid. The nipple (1) has at least one holding part (2) for invariable fastening to a body part. At its end facing the fluidic nozzle body (5), the nipple (1) has a spherical head (4). The fluidic nozzle body (5) is held on the latter by means of a ball socket (6) sealingly, but so as to be pivotable on all sides and rotable about its longitudinal axis relative to the nipple (1).

  • Patent number: 6260771
    Abstract: A valve device, in particular a window and lens cleaning device in motor vehicles, comprising a housing (1) with a duct (2) and at least one nozzle (3), and also a tubular connecting piece (4) for feeding a pressurized fluid, in particular a cleaning liquid, into the duct and to the nozzle. The connecting piece (4) is provided at its nozzle-side end with a nonreturn valve which blocks a return flow from the nozzle to the connecting piece wherein, the connecting piece (4) is open at its nozzle-side end. The nonreturn valve comprise an elastic shaped part (8) with a mouth which is normally closed and can be opened by the pressure of the cleaning liquid.

  • Patent number: 5883643
    Abstract: An apparatus for printing on flat items during conveyance thereof in an item advancing direction include a perforated transport belt having a width, an outer face and an inner face. The outer face is oriented toward a first side of the perforated transport belt and the inner face is oriented toward a second side of the perforated transport belt. A cover belt is superposed on the inner face of the perforated transport belt for holding by friction an item sandwiched between the perforated transport belt and the cover belt. A drive moves the perforated transport belt and the cover belt together in the item advancing direction. A vacuum device extends along the outer face of the perforated transport belt on the first side thereof for pressing the item, sandwiched between and advanced by the perforated transport belt and the cover belt, with a pressing force against the inner face of the cover belt in a direction substantially perpendicular to the item advancing direction.
