Publication number: 20100146940Abstract: A variable buoyancy heater is provided. It comprises variable buoyancy float that includes a variable volume element. A first fluid is contained within the variable volume element and a heating element that is integral with the variable buoyancy float is provided. The heater is arranged to heat the first fluid wherein the variable volume element expands based on a temperature increase from the heating element, such that the variable buoyancy float becomes positively buoyant when the variable volume element expands and negatively buoyant when the heating element is off.Type: ApplicationFiled: December 17, 2008Publication date: June 17, 2010Applicant: DELPHI TECHNOLOGIES, INC.Inventors: David A. Goulette, Oscar A. Lecea, Bob X. Li, Mark R. McClanahan

Patent number: 6957564Abstract: Disclosed herein is an impact absorber for an exhaust sensor. The impact absorber comprises a collar of deformable material disposed around a housing of the exhaust sensor. The collar extends radially outward from the housing. The collar may be formed from a material selected to degrade at exhaust temperature, or the collar may be formed from a material that provides radiation shielding to a portion of the sensor after installation. The collar may be disposed around a sealing gasket. A wall may be disposed around at least a portion of a perimeter of the collar, the wall being spaced apart from a plurality of facets formed on the housing to form a recess for receiving a socket wrench tool.Type: GrantFiled: February 25, 2003Date of Patent: October 25, 2005Assignee: Delphi Technologies, Inc.Inventors: Charles Scott Nelson, Mark R. McClanahan, David K. Chen, Russell H. Bosch

Patent number: 5602325Abstract: The invention includes a flat plate exhaust gas sensor having a plurality of layers of glass and steatite immediately surrounding a flat plate sensing element. A ceramic body surrounds each layer of solid-state, sintered glass and steatite and extends from each layer to a protective metal housing. A ceramic plunger presses the layers of glass and steatite. The plunger surrounds electrical connectors to the sensing element to prevent damage to the connector from heat.Type: GrantFiled: October 23, 1995Date of Patent: February 11, 1997Assignee: General Motors CorporationInventors: Mark R. McClanahan, Kaius K. Polikarpus

Patent number: 5329806Abstract: Disclosed is an exhaust oxygen sensor including a component requiring electricity to operate such as a heater or oxygen electrode. The first electrical terminal is provided in electrical contact with the component and wherein the electrical terminal has at least one male prong. The second electrical terminal in electrical contact with a wire for delivering electrical power from an external source is also provided. The second electrical terminal has at least one female connector or receptacle. The male prong and the female connector are constructed and arranged so at least one of the first and second electrical terminals is removable with respect to the other terminal. The sensor may include a threaded nut slidably received over a tubular housing, constructed and arranged to be threaded onto a threaded exhaust manifold boss without rotating the housing.Type: GrantFiled: May 11, 1993Date of Patent: July 19, 1994Assignee: General Motors CorporationInventors: Mark R. McClanahan, Bruce R. Dinger, Richard W. Duce

Patent number: 4860499Abstract: A spark plug grinding machine is equipped with force sensors to measure grinding forces and other forces attendant to a grinding operation. Ceramic spark plug insulators are carried by spindles on a Ferris wheel into a grinding station. A control wheel engages and spins each part as a grinding wheel grinds the surface of the insulator. A three axis transducer on one of the spindles measures force components along the axis of the spindle, parallel to a tangent of the grinding wheel and in a radial direction. A torque sensor on the control wheel measures the torque as the wheel rotates each insulator. Either or both of the sensors may be used. They are coupled through slip rings to a recorder.Type: GrantFiled: June 10, 1988Date of Patent: August 29, 1989Assignee: General Motors CorporationInventors: Bruce R. Dinger, Mark R. McClanahan, David B. Quinn, Frederick L. Kennard
