  • Publication number: 20120272640
    Abstract: A throttleable exhaust venturi is described herein that generates strong suction pressures at an exhaust outlet by accelerating an incoming ambient fluid stream with the aid of a venturi to high gas velocities and injecting a combustion exhaust stream into the ambient fluid stream at an effective venturi throat. A mixing element downstream of the venturi throat ensures that the mixed fluid stream recovers from a negative static pressure up to local atmospheric pressure. A physical and the effective throat of the venturi are designed to promote mixing and stabilize the ambient fluid flow to ensure that high velocity is achieved and the effective venturi is operable over a variety of combustion exhaust stream mass flow rates.

  • Publication number: 20110180032
    Abstract: An insulative piston or piston cap creates a highly thermally resistive path in the axial direction of the piston or piston cap toward a crank case of an engine. An insulative cylinder is configured to be positioned around the insulative piston and adjacent an insulative cylinder head, and to provide thermal resistance in the cylinder's axial direction. The insulated cylinder head is configured to resist heat flow in the axial direction away from the crank case. High temperature insulation surrounding these structures is configured to resist heat flow out of a combustion chamber of the engine. These insulative components, together, form the fully insulated combustion chamber.

  • Patent number: 6710419
    Abstract: An improved Schottky device, having a low resistivity layer of semiconductor material, a high resistivity layer of semiconductor material and a buried dopant region positioned in the high resistivity layer utilized to reduce reverse leakage current. The low resistivity layer can be an N+ material while the high resistivity layer can be an N− layer. The buried dopant region can be of P+ material, thus forming a PN junction with an associated charge depletion zone in the N− layer and an associated low reverse leakage current. The location of the P+ material allows for a full Schottky barrier between the N− material and a barrier metal to be maintained, thus the device experiences a low forward voltage drop.

  • Patent number: 6648207
    Abstract: This disclosure describes a technique for fusing self-fluxing metallic coatings on non-cylindrical objects without the need to conduct the fuse operation in a vacuum furnace or some other type of protective environment. The technique consists of first applying the self-fluxing coating to the surface, then optionally applying a ceramic coating on top of the self-fluxing coating. The object is then submerged into a vessel containing a low-melting inert material. The aggregate is then heated, and as the glass becomes molten, it encases the object and protects it from oxidation. As heating continues, the fusing temperature is reached and the self-fluxing alloy becomes molten. The ceramic coating encases the self-fluxing alloy and acts as a mold. When fusing is complete, the aggregate is then slowly cooled to ambient temperature. The glass frit and the ceramic shell are then removed, and one is left with an object coated with a uniform thickness of a dense adherent fused coating on the surface of the object.
