Abstract: A carburetor comprising a throttle body having six apertures positioned at a distance not to exceed 72 mm from an adjoining aperture. The float bowl housing has reciprocal threaded receptacles for receipt of a fastening bolt having a washer integrated with a hex head and an anti-vibration locking washer secured in each reciprocal. Wherein the gasket positioned between the throttle body and the float bowl housing is evenly compressed and has a predetermined distance between fasteners. The carburetor design solves a long sought need to assist carburetors in reaching or exceeding the recommended engine TBO by addressing the gasket failure that commonly occurs between the float bowl housing and throttle body assembly.

Abstract: A heated throttle plate formed from a strip of etched 304SS foil rated for 35 watts and formed into a predetermined pattern having a first end electrically coupled to a positive leadwire and a second end electrical coupled to a ground leadwire. The foil is positioned between layers of polyimide for encapsulating the foil therebetween. The leadwires are electrically coupled to a fused relay connection secured to an engine oil pressure sensor. In one embodiment the heater plate operates on 14 volts and 35 watts for heating the throttle valve to 150° F. A throttle shaft forms a channel for passage of the leadwires through the throttle body housing. The heater plate is constructed and arranged to conform to the shape of a stock throttle valve and attach thereto utilizing stock throttle valve fasteners.

Abstract: A coaxial fuel and oxygen pipe apparatus can include a fuel pipe and an oxygen pipe, wherein the fuel pipe is contained within the oxygen pipe and the oxygen pipe comprises an internal diameter that is continuous without diameter changes along a length of the oxygen pipe. The fuel pipe can include an internal diameter that is continuous without diameter variations along a length of the fuel pipe. A discharge block includes a diverging section and a discharge that forms a final outlet with respect to the fuel pipe and the oxygen pipe. The discharge block is configured with two angles that can facilitate conditions for eliminating recirculation, wherein the two angles are matched to an expansion rate of the products of combustion to maintain a positive pressure throughout a final discharge from the final outlet.

Abstract: A seal for sealing a gap in a combustion apparatus of a gas turbine between a first side and an opposite second side. The seal includes a steel strap with a flat shape and a first metal web with a flat shape attached to the steel strap on the first side and a second metal web attached to the steel strap on the second side. Thereby the seal has a seal thickness with at least the steel strap plus the first metal web plus the thickness of the second metal web, wherein the seal thickness is at most 0.2-times of width of the seal. The new seal has an Omega shape of the second metal web, which is therefore attached on both sides with a flat shaped portion to the steel strap.

Abstract: A sealing arrangement in a gas turbine engine to seal a gap between first and second turbine components is provided. The sealing arrangement includes a first arcuate feather seal connected to an anchoring assembly of the sealing arrangement affixed to the first turbine component. A second arcuate feather seal is affixed to the second turbine component. The first arcuate feather seal and the second arcuate feather seal are responsive to a pressure differential that develops across the gap to form a pressure-loaded sealing joint between respective sealing surfaces of the first arcuate feather seal and the second arcuate feather seal. The sealing arrangement provides substantial design flexibility since it can reliably provide appropriate sealing functionality while enabling multiple degrees of freedom, such as to accommodate radial and/or axial displacements that can develop between the first turbine component and the second turbine component.
