Patent number: 7793753Abstract: In a power-assisted steering system or power steering system having an electric motor, which drives a worm gear mechanism that has a composite gear wheel in the form of a worm wheel, the worm wheel includes a ring gear connectible to a hub via a first disk, and an annular projection of the first disk axially engages with the ring gear. In order to improve the centering of the component parts of the composite gear wheel in the tangential direction, and in order to render the power transmission in the gear wheel uniform, the annular projection on the first disk is provided with one or more depressions in the axial direction to form tooth-like projections, which form a drive-type toothed section and engage with depressions on an axial side face of the ring gear.Type: GrantFiled: October 8, 2004Date of Patent: September 14, 2010Assignee: ZF Lenksysteme GmbHInventors: Werner Bernhard, Oliver Hetzel, Joachim Fischer, Olaf Beutler, Achim Ottenstein, Richard Kaisser, Reinhold Schuster, Wolf-Ingo Ratzel

Publication number: 20090022941Abstract: The invention relates to self-adhesive elements which can be fastened to the most varied adhesive bodies and can be used for the most varied applications. It is the object of the invention to propose elements which can be fastened in a self-adhesive manner to the different adhesive bodies, with the fastening having to be possible in a detachable manner and a multiple use of the elements being possible. At least one sensor/pickup, an electronic element, an optoelectronic element and/or an actuator are present in a self-adhesive element in accordance with the invention. Elastically deformable pimple-shaped elevated portions are formed at a surface of the element to which an adhesive body can be connected in a self-adhesive and detachable manner. The surface of the pimple-shaped elevated portions is spherically curved at least in the region which is in touching contact with the adhesive body.Type: ApplicationFiled: May 16, 2008Publication date: January 22, 2009Applicant: Fraunhofer-Gesellschaft zur Forderung der angewandten Forschung e.V.Inventors: Wolf-Joachim Fischer, Reinhard Boden, Daniele Wiedemuth

Publication number: 20080161860Abstract: The aim of the invention is to enlarge the possibilities of use of conventional bone plates and increase their flexibility of manipulation. To this end, the invention proposes a bone plate comprising a bottom side that is to rest against the bone and an upper side opposite to the bone as well as a plurality of holes located preferably along the longitudinal axis of the plate, through which bone screws can be inserted to be anchored to a bone. At least one of these holes is a continuous oblong hole comprising a longitudinal axis running in the direction of the longitudinal axis of the plate. Thread flights are provided in a partial area of the lateral side of the oblong hole, said thread flights, when see in a direction transversal to the plane of the upper side, are arranged only over a part of the depth of the oblong hole.Type: ApplicationFiled: November 16, 2006Publication date: July 3, 2008Inventors: Uwe Ahrens, Majid Bakhshi, Hans-Joachim Fischer

Patent number: 6906468Abstract: The invention relates to a novel ballast device for pre-heating, starting and operating at least one UV emitter, constructed in the form of a gas discharge lamp with two heating coils lying opposite each other in relation to a gas discharge path, whereby four electrical connections are provided in total for each of such gas discharge paths, namely two for each heating coil. According to the invention, switching means are provided for a parallel switching of both of said connectors of a heating coil, dependent upon operating conditions. A capacitive loading of the ballast device is thus avoided by means of the otherwise open connector line for the heating coil and the current feed to the coils is evenly distributed.Type: GrantFiled: March 21, 2002Date of Patent: June 14, 2005Assignee: Wedeco AG Water TechnologyInventors: Dirk Riepe, Jan Boris Rudkowski, Joachim Fischer

Patent number: 6886338Abstract: A gas generator comprises an outflow chamber and a freeing element. The outflow chamber contains at least briefly gas under pressure, when the gas generator is activated and at least one outflow opening is arranged in a side wall of the outflow chamber. The freeing element is arranged non-displaceably in the outflow chamber and has a peripheral wall and a base wall. The peripheral wall extends along the side wall and closes at least one outflow opening before an activation of the gas generator. The base wall is connected with the peripheral wall. The freeing element is constructed so that on exceeding a predetermined gas pressure in the outflow chamber, the base wall turns inwards under partial plastic deformation of the peripheral wall and at least one hitherto concealed outflow opening is freed by the plastic deformation of the peripheral wall.Type: GrantFiled: June 9, 2004Date of Patent: May 3, 2005Assignee: TRW Airbag Systems GmbHInventors: Joachim Fischer, Michael Gabler, Achim Hofmann
