A thermal controller monitors fuel temperature and recirculates a portion of the fuel flow through a heat exchanger. The fuel delivery system can be provided as original equipment or as a retrofit.Type: GrantFiled: July 18, 2002Date of Patent: November 2, 2004Assignee: Argo-Tech CorporationInventor: Martin A.

Patent number: 6810676Abstract: A method of engine starting in a gas turbine engine comprises rotating the engine to provide an air flow into a combustor of the engine and injecting fuel into the combustor at a varying rate until the engine is lighted-off. The varying rate of the fuel flow is a function of time and is represented by a curve having at least one high frequency with respect to a light-off time, representing instant changes of the rate for intersecting a light-off zone while reducing a quantity of fuel injected into the combustor. After the light-off occurrence fuel is continuously injected into the combustor to accelerate the engine to a self-sustaining operation condition. This method of the present invention is adapted to find light-off points under various temperature and altitude conditions, thereby advantageously providing a rapid light-off, particularly under cold weather conditions.Type: GrantFiled: December 14, 2001Date of Patent: November 2, 2004Assignee: Pratt & Whitney Canada Corp.Inventor: Richard John O'Connor

Patent number: 6810678Abstract: An internal combustion engine includes an insulated combustion chamber having a fuel mixture inlet and a spark plug nearby the inlet. A series of baffles is configured within the combustion chamber to absorb a shockwave caused by ignition of fuel mixture by the spark plug. A turbine receives reduced-pressure combustion gases from an exhaust-side of the baffles and there is a power takeoff at the turbine.Type: GrantFiled: June 30, 2003Date of Patent: November 2, 2004Inventor: Chi Lam Luk

Patent number: 6810679Abstract: A cooling apparatus has a storage vessel for storing a liquefied gas and an evaporated gas produced by evaporation of the liquefied gas, a cooling head cooled by the evaporated gas to approximately a boiling temperature of the liquefied gas, piping for conveying the evaporated gas from the storage vessel to the cooling head, and a gas collection port provided at one end portion of the piping above a liquid level of the liquefied gas for collecting only the evaporated gas from the storage vessel. Thus, contamination of a gas line, needle valve, or the like, can be avoided. In addition, a liquid level sensor may be provided in the storage vessel for sensing the liquid level of the liquefied gas, so that the gas collection port may be vertically moved within the storage vessel to collect cooled gas close to the liquid level.Type: GrantFiled: February 14, 2003Date of Patent: November 2, 2004Assignee: SII NanoTechnology Inc.Inventor: Akikazu Odawara

Patent number: 6810680Abstract: An ice maker assembly in a refrigerator freezer includes a fill tube for transporting liquid to a mold. The freezer includes an outer wall spaced apart from an inner wall, with a plenum formed therebetween. An opening is formed within the inner wall, through which the fill tube extends with a clearance. Warm air generated by a defrost cycle passes through the clearance in the inner wall and around the fill tube, thereby warming the fill tube. In addition, the fill tube includes vents formed therein to allow active ventilation of the fill tube and to prevent ice formation within the fill tube.Type: GrantFiled: January 31, 2003Date of Patent: November 2, 2004Assignee: Maytag CorporationInventors: Douglas A. Pohl, William James Vestal, Kenton John Widmer
