Patent number: 8281640Abstract: A check weight (1) that is used to check a gravimetric measuring instrument, specifically a balance, or to check a further weight, is provided with a means of identification. This marking which is applied on the outside surface of the check weight includes a permanently affixed machine-readable identification code (2) which makes the specific weight piece individually recognizable. This opens the possibility for a method whereby an individually identifiable check weight can be traced back in time. A system for tracing check weights back in time includes one or more reader devices (6) that serve to record the marking, one or more processors (10) wherein the machine-readable identification code can be converted back into an identification code that can be electronically processed, and one or more data storage units, in particular a database (8) serving to store at least the data contained in the identification code.Type: GrantFiled: December 29, 2009Date of Patent: October 9, 2012Assignee: Mettler-Toledo AGInventors: Holger Haussmann, Roland Nater, Patrick Von Arx, Hans Joerg Burkhard, Michael Greuter

Patent number: 6812604Abstract: The invention relates to an electrical machine, preferably an alternator (10) for motor vehicles, comprising a rectifier assembly (11a) that is fixed to an end shield (23) of the machine. Said rectifier assembly is cooled by a fan (27) that operates in the end shield (23), the diodes being positioned on a negative connecting plate (15) and a positive connecting plate (17) of the rectifier assembly (11). The aim of the invention is to evacuate the dissipated heat from the rectifier assembly (11a) in an advantageous manner. To achieve this, the rectifier assembly is located in an opening in the front face (32) of the end shield (23) and is connected in an electrically and thermally conductive manner by one of its two connecting plates (15 and 17) to a cooling body (33), which is connected to the exterior of the end shield (23) and covers the opening (32).Type: GrantFiled: October 27, 2003Date of Patent: November 2, 2004Assignee: Robert Bosch GmbHInventors: Horst Braun, Holger Scholzen, Peter Urbach, Holger Haussmann, Dana Keppeler, Thomas Bilsing

Publication number: 20040187308Abstract: A method for fixing an electrical element, in particular a diode (20), using an insert, in particular a diode socket (26) in a support body (23), is disclosed. The insert, in particular, the diode socket (26), is applied in an opening (35) in the support body (23). Said method is characterized in that, in a further step, material of the support body (23) around the insert is forced into the insert, in order to achieve a strong connection between the electrical element and the support body (23).Type: ApplicationFiled: May 21, 2004Publication date: September 30, 2004Inventor: Holger Haussmann

Patent number: 6696914Abstract: The invention relates to an electrical fuse for rotary current generators, having a rectifier assembly (14) for supplying a DC network, in particular in motor vehicles. To achieve simple, cost-effective and rapid-response fuse performance in the event of an overload, it is provided that a fuse element (21) be disposed in a line strand, carrying all the generator current, between the rectifier assembly (14) and a DC connection terminal (22) of the generator.Type: GrantFiled: January 25, 2002Date of Patent: February 24, 2004Assignee: Robert Bosch GmbHInventors: Martin Haupt, Herbert Labitzke, Walter Csicser, Klaus-Uwe Mittelstaedt, Holger Scholzen, Karl-Otto Heinz, Holger Haussmann, Henning Stilke

Patent number: 6667532Abstract: The invention concerns a semiconductor power element (diode 18) having a lead (11) and a safety fuse (12) situated in the main current path that blows when overheated, particularly for use in the electrical system of motor vehicles. In order to achieve a previously determined, purposeful disconnection of the endangered element in order to avoid consequential damages when semiconductor power elements become overloaded, it is proposed that a segment (11b) of the lead (11) and/or its points of contact in the main current path of the semiconductor be designed as a safety fuse (12) that blows when a specified, current-dependent temperature value is reached.Type: GrantFiled: January 24, 2002Date of Patent: December 23, 2003Assignee: Robert Bosch GmbHInventors: Martin Haupt, Herbert Labitzke, Walter Csiscer, Klaus-Uwe Mittelstaedt, Hans-Heinrich Winkel, Holger Scholzen, Karl-Otto Heinz, Holger Haussmann, Henning Stilke, Hermann Lehnertz

Publication number: 20020167772Abstract: The invention concerns a bridge rectifier for rotary current generators, in particular for supplying the electrical system of motor vehicles. It comprises rectifier diodes and a printed circuit board comprising an insulator (23) basically designed in the shape of a plate, in which multiple connection conductors (24) are embedded between the diodes of the rectifier bridges, whereby sections of these connection conductors are designed to be bent extending out of the insulator and as fuses (25) that melt in case of electrical overload. In order to achieve the smallest possible tolerances for operation of the fuses, each of the fuses (25) is formed out of two conductor ends (24a)-bent to the outside-of the connection conductors (24) and a fuse element (29) connected with them that bridges the conductor ends.Type: ApplicationFiled: January 2, 2002Publication date: November 14, 2002Inventors: Martin Haupt, Herbert Labitzke, Walter Csicser, Klaus-Uwe Mittelstaedt, Holger Scholzen, Karl-Otto Heinz, Holger Haussmann, Henning Stilke, Hermann Lehnertz
