Abstract: A fuel air mixer includes a fuel air mixing tube having an inlet, an outlet, and an inlet inner diameter. A collar is attached at the mixing tube inlet and includes a first cylindrical portion upstream of the mixing tube inlet, and a body portion encircling the mixing tube at the mixing tube inlet and forming a fuel reservoir around the mixing tube inlet. The first cylindrical portion is spaced from the mixing tube inlet to create a gap placing the fuel reservoir in fluid communication with the mixing tube inlet. The first cylindrical portion has an inner diameter that is smaller than the inlet inner diameter so air flowing through the first cylindrical portion and into the mixing tube inlet draws gaseous fuel from the fuel reservoir into the mixing tube through the gap.

Abstract: A chamber is pressurized with a natural gas and air mixture. The pressure moves a piston and die to compress material to be formed into a part. The pressurized gas and air mixture is ignited with a laser beam focused with a lens or collimator into a point or fine line in a center of the chamber. Rapid combustion of the gas and air mixture drives the piston and die, compacting the part into a net shape. The focused laser beam centrally ignites pressurized gas and air mixture providing controlled combustion in the chamber and preventing damaging detonation. The focused point beam is used in chambers having length to diameter L/D aspect ratio of 2 or less than 2. The collimated thin beam is used in chambers having L/D greater than 2.

The plurality of plates have a plurality of holes in different sizes.

Abstract: A device for the physical separation of particles from a gas stream consisting of a two-dimensional flow unit in which the flow is accelerated to the throat and then diffused so that the particles are inertially urged to the core and to the trap. It is unique in that a telescope two-stage nozzle-diffuser arrangement is used to obtain a compact, low pressure loss unit. The design is such that all inertal forces including the Magnus force within the boundary layer act in the direction of particle separation towards the core and a sharp particle size cutoff is obtained down to 2 micron.

Abstract: An apparatus for improving atomization of fuel in an internal combustion engine, which apparatus has a pressure accumulation chamber connected to an intake passageway of the engine via a one-way valve and a first passageway of large flow area. The pressure accumulation chamber is also connected to the intake passageway via a second passageway of small flow area. The pressure accumulation chamber is maintained at a pressure which is close to a maximum pressure in the intake passageway. Thus, a fluid is intermittently ejected from the second passageway of small flow area into the intake passageway, thereby atomizing fuel of liquid condition therein.

Abstract: A manifold system for a two stroke cycle vertical shaft internal combustion engine. A series of horizontal bores are perpendicular to the vertical shaft. A piston located in each bore establishes a combustion chamber and a fuel-air mixture supply chamber therein. A passage connects the supply chamber to the combustion chamber and a manifold system connects the supply chamber to a mixing chamber. Each mixing chamber is connected to an independent fuel supply and to a common air supply. A valve is located between the mixing chamber and the supply chamber to control the communication of a fuel-air mixture between the mixing chamber and the supply chamber. When the piston moves toward the combustion chamber a fuel-air mixture therein is compressed and at the top of the stroke ignited to produce combustion. As the piston moves toward the combustion chamber, the supply chamber expands and draws in a fuel-air mixture.

Abstract: Carbonation enhancer having a cylindrical shell that is closed at one end by an envolute wall spaced from the inner end of a withdrawal tube, the output stream of a conventional carburetor is directed tangentially into space between the shells and caused to move in a spiral path toward the envolute closure wall by a spiral vane in the space and on reaching the envolute wall to move radially inwardly and into the inner end of the withdrawal tube to travel axially in a direction opposite that of the spiral path with the stream exiting the tube to enter the inlet manifold of the engine. Waste engine heat is applied to the exterior of the cylindrical shell in an amount sufficient to vaporize liquid fuel droplets centrifuged thereagainst from the stream as the latter traverses the spiral path portion of its travel from the carburetor to the intake manifold.
