Publication number: 20120240554Abstract: MnOx-containing, base-metal oxide mixtures (e.g., MnOx—CeO2) are useful NOx oxidation catalyst materials and NOx storage materials in lean-burn engine exhaust gas treatments using Lean NOx Trap (LNT) systems. These oxidation catalyst materials are used in combination with a NOx storage material and a NOx reduction material. MnOx-containing oxide mixtures can replace platinum (Pt) in LNT systems where the exhaust of the engine is repeatedly varied between a relatively long fuel-lean mode of operation and a relatively short fuel-rich mode of operation. The combination of the MnOx oxidation catalyst, NOx storage material, and NOx reduction catalyst material serves to complete the oxidation of unburned hydrocarbons and carbon monoxide, and to convert NOx to nitrogen.Type: ApplicationFiled: March 24, 2011Publication date: September 27, 2012Applicant: GM GLOBAL TECHNOLOGY OPERATIONS LLCInventors: Gongshin Qi, Wei Li

Publication number: 20120240591Abstract: A method and apparatus for shutting down a generator to prepare the generator for restart is disclosed. A power down sequence of a gas turbine of the generator is initiated from an operating state. A purge gas is forced into the gas turbine to extinguish a combustion flame in the gas turbine. The purge gas is swept through the gas turbine to displace the fuel from the gas turbine using a coast down airflow through the gas turbine during the power down sequence to prepare the generator for restart.Type: ApplicationFiled: June 6, 2012Publication date: September 27, 2012Applicant: GENERAL ELECTRIC COMPANYInventors: David August Snider, Michael Joseph Alexander, Robert Lester Brooks, Elsie Angelly Carantini, Michael James Dutka, Christopher John Morawski, Eugene Armstead Post

Publication number: 20120240593Abstract: A method and apparatus for heating fuel in an aircraft gas turbine engine, for example to provide fuel anti-icing to the fuel, comprises directing a fuel flow through a heat exchanger associated with a generator power conditioning unit as a sole means for providing anti-icing heating to fuel supplied for engine combustion. The method and apparatus permits the heat exchanger to heat the fuel sufficiently so that other dedicated heating means may be unnecessary.Type: ApplicationFiled: March 22, 2011Publication date: September 27, 2012Applicant: PRATT & WHITNEY CANADA CORP.Inventor: Ian A.

Publication number: 20120240594Abstract: An aircraft engine generates engine power by burning hydrocarbon fuel such as Jet-A. A minute quantity of the fuel is burned in such a manner as to generate no engine power, and the heat generated by the burning fuel is used to protect a region of a surface of a component of an aircraft. In one application, burner assemblies are located inside the splitter of a turbofan engine and the heat generated is used to deice or anti-ice the splitter and the inlet guide vanes of the engine. In another application, burner assemblies are located in an engine nacelle to deice or anti-ice the leading edge of the nacelle.Type: ApplicationFiled: July 26, 2011Publication date: September 27, 2012Applicant: COX & COMPANY, INC.Inventor: Pavel SHAMARA

Publication number: 20120240595Abstract: A combustion chamber head of a gas turbine has a base plate 113 provided with a centric recess 121 in which at least one burner 106 is arranged, with the base plate 113 being connected to walls of the combustion chamber 108 and to a burner seal 116 sealing the burner 106 towards the rim of the recess 121. The burner seal 116 is arranged upstream of the base plate 113 and can be brought into contact with a collar 118 provided on the base plate 113 and forming the rim of the centric recess 121. A holding element 117 of the burner seal 116 is formed as a ring and arranged upstream of the burner seal 116 and engages with at least one projection 114 of the base plate 113 in a tension-free state.Type: ApplicationFiled: March 23, 2012Publication date: September 27, 2012Applicant: ROLLS-ROYCE DEUTSCHLAND LTD & CO KGInventor: Miklos GERENDAS

Publication number: 20120240596Abstract: A thermoelectric conversion unit includes first and second cases including first and second recesses that define first and second flow passages and have openings, first and second substrates, a plurality of thermoelectric devices in contact with the inner surfaces of the first and second substrates, a connector for joining the first and second cases, first and second fins protruding from the first and second substrates in the first and second flow passages. The first and second cases include first and second opposed portions opposed to the first and second substrates outside the first and second recess, respectively. A spacer for setting distance between the first opposed portion and the second opposed portion is provided. The spacer sets the distance between the first and second opposed portions to be longer than distance between the outer surface of the first substrate and the outer surface of the second substrate.Type: ApplicationFiled: March 9, 2012Publication date: September 27, 2012Applicant: KABUSHIKI KAISHA TOYOTA JIDOSHOKKIInventors: Motoaki Okuda, Naoya Yokomachi, Hiromi Ueda, Junki Nakamura

Publication number: 20120240598Abstract: One aspect of the present invention may include a heat pump system having a Peltier unit in an outdoor space and an outdoor heat exchange unit in the outdoor space. The Peltier unit has a Peltier element with a heat-absorbing portion and a heat-radiating portion, a first substrate in contact with the heat-absorbing portion, a second substrate in contact with the heat-radiating portion, a metal case and a resin case. The metal case covers the first substrate and forms a first flow path between itself and the first substrate. The first flow path is connected in a loop-like fashion to the outdoor heat exchange unit by an outdoor piping. The resin case covers the second substrate and forms a second flow path between itself and the second substrate. The second flow path is connected in a loop-like fashion to the indoor heat exchange unit by an indoor piping.Type: ApplicationFiled: March 19, 2012Publication date: September 27, 2012Applicant: KABUSHIKI KAISHA TOYOTA JIDOSHOKKIInventors: Hiromi UEDA, Naoya YOKOMACHI, Motoaki OKUDA, Junki NAKAMURA
