Patent number: 6671953Abstract: A method for fabricating a cable-in-conduit-conductor for use in superconductor application is described. The system utilizes a work surface with drum means provided at each end. A superconductor cable is fed from a supply source at one end. After the cable is pulled through a tube on the work surface, the leading edge of the cable is bent around one of the drums and returned to the opposite end of the table. This naked length of cable is once again bent around one of the drums and then pulled through another tube on the table. This process is repeated until an acceptable length of superconductor cable is present. Tension means are used in conjunction with a tube mill which compresses the tube-cable combination into a viable cable-in-conduit conductor (CICC). Notably, as this tension-compression is occurring, the naked lengths of cable are eliminated and each separate tube section is joined together to create a uniform CICC.Type: GrantFiled: October 29, 2001Date of Patent: January 6, 2004Assignee: BWX Technologies, Inc.Inventors: Michael D.

Patent number: 6560865Abstract: An arrangement apparatus comprises a base (10) and an elongated arranging member (12) mounted thereon, wherein the arranging member includes a plurality of channels (123) and a plurality of reference wires (1253) with predetermined colors. The reference wires are arranged in a sequence that corresponds to the arrangement of pins of a connector to be connected with the multi-core round cable. Each reference wire is disposed in alignment with a corresponding channel. The color of each reference wire is the same as the color of a core (21) of the multi-core round cable to be placed in the channel corresponding to that reference wire. An operator can freely pick up any one core and place it in the correct channel simply by matching the color of the reference wire with the color of the selected wire.Type: GrantFiled: April 27, 2001Date of Patent: May 13, 2003Assignee: Hon Hai Precision Ind. Co., Ltd.Inventor: Wenli Wang

Patent number: 6557252Abstract: A method and apparatus for fabricating uniform splices for stranded cables. A joint for a stranded cable can be formed by inserting the ends of two cables into an electrically conductive splice band which, in turn, is inserted into a coil or inductor. The splice is fabricated by a process known as magnetic pulse forming, or magnetic pulse welding wherein a very large electrical current of short duration is directed through the coil or inductor from a charged capacitor bank. The resulting magnetic field in the coil or inductor induces a magnetic field on the splice band, compressing the splice band uniformly around the circumference of the two cable ends being spliced. In the case of magnetic pulse welding, the splice not only uniformly compresses the stranded cables, but a weld is also created between the inner diameter of the sleeve and the adjacent stranded cables.Type: GrantFiled: December 14, 2000Date of Patent: May 6, 2003Assignee: Fuel Cell Components and Integrators, Inc.Inventors: Richard A. Bennett, Robert L. Benoit, Bernard I. Rachowitz, Glenn L. Spacht

Publication number: 20030079343Abstract: An system and method for fabricating a cable-in-conduit-conductor for use in superconductor application is described. The system utilizes a work surface with drum means provided at each end. A superconductor cable is fed from a supply source at one end. After the cable is pulled through a tube on the work surface, the leading edge of the cable is bent around one of the drums and returned to the opposite end of the table. This naked length of cable is once again bent around one of the drums and then pulled through another tube on the table. This process is repeated until an acceptable length of superconductor cable is present. Tension means are used in conjunction with a tube mill which compresses the tube-cable combination into a viable cable-in-conduit conductor (CICC). Notably, as this tension-compression is occurring, the naked lengths of cable are eliminated and each separate tube section is joined together to create a uniform CICC.Type: ApplicationFiled: October 29, 2001Publication date: May 1, 2003Inventors: Michael D. McAninch, James G. Hatmaker

Patent number: 6550137Abstract: The device is a tool for placing a split sheath around elongated items such as bundles of electronic cables. It comprises a guide bush which makes possible the opening of the sheath, a duct for the cables to be sheathed, lateral grooves for guiding the open sheath and is characterized by the presence of a lateral opening which allows the introduction or extraction of cables possibly already fixed at their two extremities during the use of the tool, as well as by the angle which there is between this opening and the duct for the cables in a manner to keep them in position in the tool be their own rigidity. The tool may have a handle for manipulation and for setting the tool in relative motion along the cables to be sheathed. The invention is also directed at the method for using the tool.Type: GrantFiled: January 10, 2000Date of Patent: April 22, 2003Assignee: Federal-Mogul Systems Protection Group S.A.S.Inventor: Jean Henri Ferrand

Publication number: 20030066185Abstract: In a system for preparing a wire harness production, a modified wiring pattern generator generates modified wire harness wiring pattern information related to at least one second pattern in which at least one of parts, electric circuits, and wirings of a first pattern including the parts, the electric circuits, and the wirings of a standard type vehicle is altered. A parts information storage stores parts specification information including specifications of the parts, the electric circuits and the wiring included in the second patterns. A simulator simulates whether each of the second patterns is practical while referring to the parts specification information. A sub wiring pattern modifier modifies at least one of first sub patterns constituting the first pattern to at least one of second sub patterns so as to constitute the second pattern judged as practical by the simulator.Type: ApplicationFiled: October 3, 2002Publication date: April 10, 2003Applicant: YAZAKI CORPORATIONInventors: Kenichiro Akizuki, Shuji Ono, Tetsuya Ishiguro, Masaya Uchida, Yasuhiro Mochizuki, Eiji Asaoka, Takeshi Ishikawa

Publication number: 20030066190Abstract: An equipping installation introduces fitted-out cable ends into plug housings and is arranged downstream from a fitting-out installation. A contact for the first plug housing is arranged at the leading cable end and a contact for the second plug housing is arranged at the trailing cable end. A feeder unit takes over the cable loop fitted-out to a finished state from a second transfer unit and transfers the leading cable end to a positioning unit and the trailing cable end either to a rotatable store or, after the positioning unit is again free of cable, to the positioning unit in accordance with a cable plan. An equipping unit takes over the cable ends in succession at the positioning unit and introduces the cable ends into the corresponding plug housings.Type: ApplicationFiled: October 7, 2002Publication date: April 10, 2003Inventors: Jean Revel, Claudio Meisser

Patent number: 6539620Abstract: A method for producing superalloy weld wire and weld wire having fewer inclusions, and specifically fewer hafnia inclusions, and superalloy weld wire, particularly hafnium-containing superalloy weld wire, produced by this method. The method includes producing directionally solidified cast rod in a diameter of less than about ½ inch. The rod preferably is produced by investment casting or by continuous casting. The directional solidification process results in rod having inclusions such as oxides and dirt segregated into portions of the casting where they are easily removed. The cast rod can then be formed into semi-finished weld wire using a single extrusion step, followed by grinding to the final required diameter.Type: GrantFiled: January 19, 2000Date of Patent: April 1, 2003Assignee: General Electric CompanyInventor: Russell W.
