Patent number: 8816197Abstract: A pressure-balanced electrical cable assembly including a connector body, an electrical conductor positioned within the connector body, an interior chamber defined within the connector body, a dielectric fluid medium contained within the chamber, and a shuttle delimiting at least a portion of the chamber to prevent the escapement of the dielectric fluid from the chamber. The shuttle is moveable in response to differences between a pressure within the chamber and a pressure outside of the chamber.Type: GrantFiled: October 15, 2013Date of Patent: August 26, 2014Assignee: ITT Manufacturing Enterprises LLCInventors: Charles O. Campbell, Roger C. Williams, Jeffrey Hamilton-Gahart

Patent number: 8708726Abstract: A replaceable sealing element for sealing together two mating electrical connectors includes a sealing body having two opposed ends, a side wall extending between the two opposed ends, a threaded portion that is defined on the side wall for releasably mating with a first electrical connector of the mating electrical connectors, and either a slot or a protrusion at one of the opposed ends of the sealing body that is configured to be accessed by a tool for replacing the sealing element. A first seal is positioned on the side wall for sealing contact with the first electrical connector. A second seal is positioned on the side wall for sealing contact with a second electrical connector of the mating electrical connectors. Also described is an electrical connector having a replaceable sealing element.Type: GrantFiled: August 1, 2012Date of Patent: April 29, 2014Assignee: ITT Manufacturing Enterprises LLCInventors: Charles O.

Patent number: 8011031Abstract: A toilet assembly is provided having a bowl assembly having an inlet, a wastewater outlet, and a water supply inlet having an inlet valve. The assembly includes an adjustable metering valve in fluid communication with the inlet valve and the inlet of the bowl assembly, and an accumulator in fluid communication with the inlet valve and disposed upstream of the adjustable metering valve. A fragmentation passage is provided in fluid communication with the wastewater outlet and disposed downstream of the wastewater outlet. The assembly includes jet assembly having an inlet in fluid communication with the inlet valve, and an outlet disposed upstream of the fragmentation passage. The water supply inlet is structured to deliver a quantity of water through the inlet of the bowl assembly, and a quantity of water to the jet assembly to remove wastewater from the fragmentation passage.Type: GrantFiled: June 9, 2008Date of Patent: September 6, 2011Assignee: Wabtec Holding Corp.Inventors: Charles O. Campbell, William E. Wood

Patent number: 7383593Abstract: A toilet assembly is provided having a bowl assembly, a fragmentation passage, a jet assembly, and a water system. The bowl assembly has a wastewater inlet and a waste water outlet. The fragmentation passage has a passage, an inlet, and an outlet. The fragmentation inlet and outlet are each in fluid communication with the passage. The passage has an upper portion, that is above a water line, and a lower portion, that is below a water line. The fragmentation inlet coupled to, and in fluid communication with, the bowl assembly waste outlet. The jet assembly has an inlet and an outlet. The jet assembly is coupled to, and in fluid communication with, the passage lower portion. The water system is coupled to and in fluid communication with the bowl assembly and the jet assembly. The water system is structured to deliver a quantity of water to the bowl assembly and the jet assembly and to remove wastewater from the fragmentation passage.Type: GrantFiled: December 16, 2004Date of Patent: June 10, 2008Assignee: Wabtec Holding CorporationInventor: Charles O.
