Abstract: A gas turbine engine includes a compressor, a turbine, and a combustor. The combustor includes a fuel injector and a vaporizer within the combustor positioned to receive liquid fuel from the fuel injector to vaporize the liquid fuel therein. The gas turbine engine includes an enclosed passage external to the combustor having a wall, a diffuser positioned to direct the air into the passage, causing the air to cool by transferring heat through the wall from the air within the passage to the vaporized fuel within the vaporizer, and a cooled cooling air passageway positioned to receive the air from the passage and direct the air after being cooled to at least one of the turbine and the compressor.

Abstract: A gas turbine engine having a combustor is disclosed in which a heat exchanger is disposed within the combustor. The heat exchanger can take the form of a fuel/air heat exchanger. In one form the heat exchanger includes a path for cooling air to be conveyed to a location external to the combustor. Cooled cooling air carried through the path can be created through action of heat transfer from the cooling air to a fuel flowing in the heat exchanger. The heat exchanger can include a fuel vaporizer in one form.

Abstract: A gauge wheel assembly for a farming implement is disclosed which comprises a hub portion positioned substantially centrally with respect to the assembly, a rim portion forming a circumference of the assembly and forming a circumferential ground contacting surface; and an intermediate portion positioned between and connecting the hub portion and the rim portion. The intermediate portion comprises a hub side section positioned about the hub portion, a rim side section positioned inwardly of the rim portion, and a plurality of spoke sections extending from the hub side section to the rim side section and connecting the hub side section to the rim side section. The rim side section encircling the plurality of spoke sections. The hub side section of the intermediate portion defines an aperture with the hub portion being positioned in the hub side section. The intermediate portion is separable from the rim portion and the hub portion.

Abstract: An apparatus for mixing fuel with oxidizing agent is disclosed comprising an outer body and an inner body. The outer body has an interior surface extending between an inlet end toward an outlet end. The interior surface includes a first plurality of openings. The inner body has an exterior surface extending between the first end and the second end of the inner body. The exterior surface of the inner body includes a second plurality of openings. At least a portion of the exterior surface of the inner body is positioned within the outer body to define a mixing channel between the exterior surface of the inner body and the interior surface of the outer body. In one form the first and second plurality of openings substantially longitudinally span at least one of the outer body and the inner body. In another form the first and second plurality of openings are substantially radially oriented. In yet another form the first and second plurality of openings are offset from one another.

Abstract: The present invention relates generally to a lean premix module for an industrial gas turbine engine to satisfy increasingly stringent environmental requirements. A combustion system of the present invention employs a lean premix technique to meet the engine operability requirements and high power emission targets without the use of combustor diluent injection or post combustor exhaust treatment. A lean premix combustion mode is utilized to minimize primary zone combustion temperatures and limit the oxides of nitrogen production during high power engine operation. In one form of the present invention, the lean premix combustion is carried out in an off centerline silo combustor having a plurality of lean premix modules positioned parallel within a common liner. The lean premix modules receive the air from the compressor into a radial swirler and the fuel is dispensed along the radial swirler in order to be premixed with the air.

Abstract: The present invention relates generally to a low emission can-annular combustion system for an industrial gas turbine engine to satisfy increasingly stringent environmental requirements. The combustion system of the present invention employs a dual mode combustion technique to meet engine operability requirements and high power emission targets without the use of combustor diluent injection or post combustor exhaust treatment. A lean premix combustion mode is utilized to minimize primary zone combustion temperatures and limit the oxide of nitrogen production during high power engine operation. A pilot-starting auxiliary fueling system is utilized to augment the main premix fueling system. The lean premix combustion mode is enabled by a lean premix dome having a fixed axial swirler with radial fuel pathways connecting to a circumferential main fuel manifold for distributing the fuel more uniformly across the flow path.

Abstract: A system for use in conjunction with a digital data processing system includes an applications program, a user interface and a hierarchy information management system. The applications program generates an information hierarchy including a plurality of hierarchy information items organized in a plurality of hierarchy levels. The user interface includes a display for displaying information to a user and an event initiator, such as, for example, a keyboard or a mouse for generating event information. The hierarchy information management system receives hierarchy information items at selected hierarchy levels from the applications program and transmits the received hierarchy information items to the display of the user interface for display, and responds to the event information by initiating selected operations in connection with the received hierarchy information.
