Patent number: 7726216Abstract: A structural component, especially a shielding component, has structural parts (10, 12, 14, 16, 18) at least in part differently configured with respect to their surface extent and/or the directional pattern. At least one structural part (10) of a first type is provided with a curvature and with a longitudinal orientation. Structural parts (12) of a second type at least in part follow that curvature. Since the structural part (10) of the first type is designed as a shell and since the structural parts (12) of the second type are combined in pairs into groups (20, 22) and extend transversely to the longitudinal orientation of the structural part (10) of the first type, the edge area is strengthened by an additional structural part. The additional structural part is an integral component of the shielding body and does not need mounting-bracket parts positioned on the edge side.Type: GrantFiled: May 18, 2005Date of Patent: June 1, 2010Assignee: ElringKlinger AGInventors: Dieter Hofmann, Markus Lang

Publication number: 20100121162Abstract: Embodiments of a child-friendly analyte measurement system are provided for detecting at least one analyte in a bodily fluid. A measurement system comprises at least one measurement instrument for detecting the analyte in the bodily fluid, such as a commercially available measurement instrument. The measurement instrument is configured as a portable hand-held instrument and has a housing with at least one display element. Furthermore, the measurement system comprises a toy, in particular a figurine or a toy animal. The toy has at least one receptacle for reversibly holding the measurement instrument, which receptacle is configured such that if the measurement instrument is held by the receptacle, the display element is accessible, at least in part. The measurement instrument is configured such that it can be used both in the measurement system and also, optionally, independently of the toy. Further aspects include a kit, a method, and the toy for the provided measurement system.Type: ApplicationFiled: October 16, 2009Publication date: May 13, 2010Inventors: Martin Klinke, Dieter Hofmann

Patent number: 7640733Abstract: A structural part, especially a shielding component, has structural parts (10, 12, 14, 16) at least in part differently configured with respect to their surface extent and/or the directional pattern. At least one structural part (10) of a first type is provided with a curvature at least partially increasing in the direction of at least one edge area (20). Structural parts (12) of a second type at least in part follow the curvature (18) of the first structural part. In each curved edge area (20), at least one structural part (14) of a third type is provided, according to the position in which the structural parts (12) of the second type are oriented and extend continuously at least in the area of the change in the curvature toward the edge area (20) along the first structural part (10). The edge area is strengthened by an additional structural part which, in addition to low-vibration behavior, leads to a clear reduction of acoustic propagation of noisy engine components.Type: GrantFiled: May 18, 2005Date of Patent: January 5, 2010Assignee: ElringKlinger AGInventors: Dieter Hofmann, Markus Lang

Publication number: 20090068450Abstract: The invention relates to a method for operating a multi-cathode-PVD-coating system. According to the invention, one part of the cathodes operates after the high power impulse cathodic sputtering which is assisted by magnetic fields and the remainder operates after the direct current magnetic field assisted cathodic sputtering. The high power impulse cathodic sputtering which is assisted by magnetic fields is used as a source of multi-ionised metal ions during the ion-assisted in vacuo pre-treatment of substrates, whilst both types of cathodic sputtering are always used simultaneously during coating and whilst both types of cathodes are connected to different materials.Type: ApplicationFiled: July 11, 2006Publication date: March 12, 2009Inventors: Wolf-Dieter Muenz, Dieter Hofmann, Stefan Kunkel, Juergen Mangold, Hans Schuessler

Patent number: 7458209Abstract: A shielding component, in particular a heat shield, has at least two shield components (10, 12) which can be connected to each other by a connection unit (14). Because the connection unit (14) has a guide (16) which enables adjustment of the relative positions of the individual shield components (10, 12) to each other and which is used for fastening in the adjusted position. A sliding heat shield concept arises in which, with a heat shield having several shield components, adaptation is possible on site to the geometrical conditions of engines and their add-on parts including exhaust systems. Effective sound damping and heat insulation can be produced in a wide area with only one shielding component and its shield components.Type: GrantFiled: February 8, 2006Date of Patent: December 2, 2008Assignee: ElringKlinger AGInventors: Dieter Hofmann, Bernd Ell

Patent number: 5446341Abstract: To provide a tight seal between an essentially solid niobium or tantalum necting pin or rod (10) passing through an opening (7, 28) in an end plug (11) closing off a high-pressure discharge lamp discharge vessel (8), the pin or rod is formed with two axial portions, one of which has externally projecting continuous rings (17), preferably two or three, or an externally projecting thread (26). The rings or thread are press-fitted into the end portion of the bore in the plug, which deforms the edge (20) of the rim, ridge or thread, or shears off the edge portion, ensuring a tight preliminary fit in the bore; sealing glass, which is then melted to fill a capillary space between the pin or rod and the plug, is protected by the preliminary seal against corrosion or attack from the fill within the discharge lamp; if the projection is in form of a thread, glass can penetrate within the threads to further seal and retain the pin or rod.Type: GrantFiled: May 27, 1993Date of Patent: August 29, 1995Assignee: Patent-Treuhand-Gesellschaft F. Elektrische Gluehlampen mbHInventors: Dieter Hofmann, Stefan Juengst

Patent number: 5382171Abstract: The present invention is directed to an electrical plug-in socket, especially for motor vehicles, which has a hinged lid, a compression spring, for the hinged lid, a chamber for the compression spring molded to the socket housing, and a cam provided with a control curve and molded to the hinged lid. The cam cooperates in such a way with the compression spring, that the hinged lid is automatically held in one of the closed and the open position. In order to simplify the assembly or installation of the hinged lid and in order to lower the material and installation costs, the compression spring is designed as a leaf spring and is molded into the chamber of the plug-in socket housing. The leaf spring has a spherical section-shaped rise for the control curve of the cam.Type: GrantFiled: July 28, 1993Date of Patent: January 17, 1995Assignees: Schoeller & Co., Elektrotechnische Fabrik GmbH & Co.Inventors: Dieter Hofmann, Berthold Kalkus

Patent number: 5330853Abstract: Surface coating includes alternating first and second ternary layers, wherein the first layer TiAlN.sub.x has a higher nitrogen content and is considerably thinner than the second layer TiAlNy. The first layer is preferably applied by decreasing the nitrogen content of a reactive atmosphere from a maximum to a minimum during sputtering of a TiAl target. The second layer is then applied by sputtering the TiAl target over a longer period of time while the nitrogen content is maintained constant at the minimum. When a further first layer is applied, the nitrogen is again increased to the maximum.Type: GrantFiled: August 19, 1991Date of Patent: July 19, 1994Assignee: Leybold AGInventors: Dieter Hofmann, Bernd Hensel
