Publication number: 20050225169Abstract: A braking device is disclosed wherein the braking device is configured to aid in slowing down a towed vehicle. The braking device includes a brake actuator, which is preferably configured to controllably press on the towed vehicle's brake pedal; a controller, which is preferably configured to control the brake actuator; and, a voltage regulator system, which is preferably configured to monitor the energy level of the towed vehicle battery. When the voltage regulator system detects the energy level of the towed vehicle battery to have reached a predetermined energy level, the voltage regulator system is preferably configured to save the towed vehicle battery's remaining energy by substantially preventing the towed vehicle battery from supplying energy to the brake actuator. When the voltage detector receives a signal from the controller to supply the brake actuator with energy, the voltage regulator system is preferably configured to allow the brake actuator to use the remaining energy.Type: ApplicationFiled: May 25, 2005Publication date: October 13, 2005Applicant: Jerry A.EdwardsInventors: Robert Skinner, M. Walker, Terry Elstad

Patent number: 6651986Abstract: A rotary machine has a stationary component with circumferential grooves and a rotatable component, as well as annular packing or sealing ring segments movable toward and away from the rotating component. To prevent circumferential displacement of the lower side packing ring segments by gravity forces and enable the lowermost segment in the lower housing to be moved radially inwardly, the side segments of the lower housing are supported adjacent the casing midline in a manner preventing downward movement and enabling horizontal movement. In an exemplary embodiment, the lower side packing ring segment is elongated so as to extend above the horizontal joint of the housing and a key bar extends from a key bar groove in the housing to engage a corresponding groove in the segment. The key bar may be disposed to define a seal key for the horizontal joint.Type: GrantFiled: January 29, 2002Date of Patent: November 25, 2003Assignee: General Electric CompanyInventors: Richard Jon Chevrette, David Robert Skinner, George Horner Kirby, II, Christopher Edward Wolfe

Patent number: 6477916Abstract: A balance weight has first and second margins at right angles to one another with the second margin larger than the first margin. A balance weight groove in a rotor has outer and inner wall portions, with the outer wall portions spaced a distance less than the spacing between the inner wall portions. The balance weight has a central threaded opening receiving a screw and a driving slot in the upper face of the weight. An insertion tool is threaded to the balance weight to insert the balance weight through a turbomachinery access opening into the groove. The tool is rotated to locate the second margins below the outer wall portions of the groove. By inserting a driving tool through the insertion tool, the screw is rotated to lock the balance weight to the rotor and in the groove. Upon removal of the insertion and driving tools, a staking tool is inserted through turbine access opening to stake the balance weight and rotor and the screw and balance weight.Type: GrantFiled: June 7, 2001Date of Patent: November 12, 2002Assignee: General Electric CompanyInventors: Victor John Knorowski, David Robert Skinner, Alexander Morson

Patent number: 6435513Abstract: A brush seal is comprised of arcuate seal segments having ends cut in a radial direction with bristles “canted” at an approximate 45° angle relative to radii of the segments, leaving triangular regions adjacent one end of each segment devoid of bristles at the segment interfaces. The brush seals are retrofit into conventional labyrinth seals with the backing plate for the bristles comprising a labyrinth tooth profile extending fully 360° about the seal, including those areas where bristles are not present. The sealing capacity is not substantially degraded, while affording significant sealing improvements over conventional labyrinth seals. Additionally, when retrofit into labyrinth seals with radial movement, the individual labyrinth seal segments are free to move radially independently of one another during transients.Type: GrantFiled: February 26, 2001Date of Patent: August 20, 2002Assignee: General Electric CompanyInventors: David Robert Skinner, Bharat S.

Patent number: 6295684Abstract: An apparatus is disclosed for the cleaning of solubly marked laminated sheets. A laminated sheet is fed over a cleaning surface along which are disposed a plurality of solvent-carrying wipers. The solvent-carrying wipers will wipe the markings from the sheet and the sheet feeder will then deposit the wiped sheet at the other end of the apparatus. Drying means could wipe excess solvent from the sheet following its passage over the wipers. The device will be of particular assistance in the gaming industry, where reusable gaming cards might be substituted for disposable paper cards currently employed for substantial economic savings.Type: GrantFiled: April 23, 1999Date of Patent: October 2, 2001Inventor: Robert Skinner

Patent number: 6131910Abstract: Brush seals are retrofitted into existing turbine labyrinth seal rings to create a fail-safe seal design at locations wherever labyrinth seals are currently used, including interstage shaft seals, rotor end seals, bucket (or blade) tip seals and spill strips. Brush seals, per se, when used in place of labyrinth seals, can result in considerable span reductions of steam turbines, or machines with more turbine stages for a given span. Application to end packings results in the potential elimination of gland sealing/exhauster systems. Brush seal life can be improved by retrofitting brush segments to labyrinth seal segments that are either spring-backed, or use pressure loads to obtain design clearances only after steady state operating conditions are achieved. The brush seals are provided with backing plates shaped like labyrinth teeth, resulting in a fail-safe design.Type: GrantFiled: May 13, 1997Date of Patent: October 17, 2000Assignee: General Electric Co.Inventors: Bharat S.

Patent number: 6105966Abstract: A brush seal segment useful, when circumferentially arrayed with other such segments, to seal the gap between a rotor and a surrounding casing of a rotary machine such as a steam turbine. An annular backing plate has a rim radially-inwardly bounding together upstream-facing and downstream-facing surfaces. Canted bristles abut the upstream-facing surface. The rim is designed to allow the bristles to recover from a rotor rub. In one design, the rim acts as a labyrinth-seal tooth and is shaped to deform, under a radial force, longitudinally away from the upstream-facing surface. In another design, the rim has a more-inwardly projecting second portion near a radially-aligned edge, and only this second portion acts as a labyrinth-seal tooth.Type: GrantFiled: August 10, 1998Date of Patent: August 22, 2000Assignee: General Electric CompanyInventors: Norman Arnold Turnquist, Osman Saim Dinc, George Ernest Reluzco, Robert Harold Cromer, David Robert Skinner, Christopher Edward Wolfe
