Patent number: 6633004Abstract: The electrical insulator has an insulator body 3 which is fitted between an electrical conductor 1 and a grounded holder 2. The surface of the insulator is at least partially formed by a protective body 6. The material of the protective body has a low dielectric constant in comparison to that of the material of the insulator body 3. The protective body 6 prevents an electrically conductive particle 12 from coming to rest directly on the surface of the insulator body 3, in particular in the region of the triple points T, or causing a considerable increase in the field due to immediate proximity to the insulator body 3. The breakdown voltage of a gas-insulated system which contains such insulators provided with a protective body is increased. Gas-insulated systems can thus be made more compactly and more cheaply, and their life can be extended.Type: GrantFiled: November 30, 2001Date of Patent: October 14, 2003Assignee: ABB Research LtdInventors: Christoph Heitz, Lutz Niemeyer, Marco Piemontesi

Patent number: 6627811Abstract: A cable protective shield assembly is provided for managing the position of computer cables. The assembly includes a base plate having a number of spacers formed on one surface, a cover plate having a number of bores extending through the plate at locations designated in alignment with the spacers of the base plate, and a corresponding number of fasteners for insertion through the bores of the cover plate into the spacers of the base plate to rigidly couple the plates together. The height of the spacers create a standoff distance between the base plate and cover plate defining a space for computer cables to extend. The spacers are also positioned across the base plate surface as to create specific passageways for the cables to be located. One or more ports can be placed along the perimeter of the cover plate to allow access to cable connectors while generally maintaining the organized position of the cables.Type: GrantFiled: July 31, 2001Date of Patent: September 30, 2003Assignee: Hewlett-Packard Development Company, L.P.Inventors: Brandon Rubenstein, Eugene A Miksch

Patent number: 6610921Abstract: A container system including a vessel for holding a thixotropic semi-solid aluminum alloy slurry during its processing as a billet and an ejection system for cleanly discharging the processed thixotropic semi-solid aluminum billet. The crucible is preferably formed from a chemically and thermally stable material (such as graphite or a ceramic). The crucible defines a mixing volume. The crucible ejection mechanism may include a movable bottom portion mounted on a piston or may include a solenoid coil for inducing an electromotive force in the electrically conducting billet for urging it from the crucible. During processing, a molten aluminum alloy precursor is transferred into the crucible and vigorously stirred and controlledly cooled to form a thixotropic semi-solid billet. Once the billet is formed, the ejection mechanism is activated to discharge the billet from the crucible. The billet is discharged onto a shot sleeve and immediately placed in a mold and molded into a desired form.Type: GrantFiled: August 24, 2000Date of Patent: August 26, 2003Inventors: Christopher John Brannon, Gerard E.
