  • Patent number: 6986208
    Abstract: A blade has a hard, thin layer of ceramic on one side, so that when the blade is sharpened on the other side the very hard ceramic is disposed at the cutting edge. The ceramic (for example, TiN) may be deposited by vacuum deposition. The surface onto which the ceramic is deposited is specular (mirror-like), so that it is flat or smooth on the order of a wavelength of light. The ceramic layer, which is very thin, takes the form of a flat plate, when viewed on a microscopic scale. The ceramic forms a cutting plate at the edge of the blade.

  • Patent number: 6986213
    Abstract: A method for drying a granular solid, the finely divided solid to be dried being mixed with zeolite granules, after which drying takes place by removal of water from the solid. The solid dried by removal of moisture is then separated from the zeolite. According to the invention, the solid to be dried is dried in a mixer without external supply of heat, after which the dried solid is at least virtually completely separated from the zeolite granules after a residence time in the mixer. This is advantageous in particular when drying foods, such as wheat flour.

The side thruster valve comprises a valve plug having its back directed to an axis of the aerospace craft and independently movable between a fully opened position and a fully closed position of the valve plug in a plane orthogonal to the axis of the aerospace craft, an actuating means for moving the valve plug in an axial direction of the valve plug and an elastic member for activating the valve plug in the axial direction of the valve plug. In a side thruster device comprising a plurality of the side thruster valves, the side thruster valves are arranged independently of each other to thereby broaden freedom of combustion control and improve fuel consumption.

  • Patent number: 6986247
    Abstract: An automobile catalytic converter that utilizes the energy of the exothermic reactions that take place in the catalysis substrate to produce electrical energy with a thermoelectric generator. On vehicle cold start, the thermoelectric generator is used as a heat pump to heat the catalyst substrate to reduce the time to catalyst light-off. In this way, the catalytic converter comes up to operating temperature more rapidly, reducing the amount of pollutant emissions at vehicle start-up.

  • Patent number: 6986250
    Abstract: A tool for bleeding a master cylinder when the master cylinder is unattached to a vehicle. In an exemplary embodiment a bleeding tool includes a shaft attached by means of clamp rods to a master cylinder flange, a clamp handle rotatable with respect to the shaft, and a push rod coupled to the clamp handle through a movable rotatable joint. In an exemplary embodiment, the maximum motion of the push rod during a bleeding cycle is defined by a set of two pins disposed on a ring concentric with the shaft.

  • Patent number: 6986251
    Abstract: In a waste heat recovery system wherein an organic rankine cycle system uses waste heat from the fluids of a reciprocating engine, provision is made to continue operation of the engine even during periods when the organic rankine cycle system is inoperative, by providing an auxiliary pump and a bypass for the refrigerant flow around the turbine. Provision is also made to divert the engine exhaust gases from the evaporator during such periods of operation. In one embodiment, the auxiliary pump is made to operate simultaneously with the primary pump during normal operations, thereby allowing the primary pump to operate at lower speeds with less likelihood of cavitation.

  • Patent number: 6986254
    Abstract: A method of operating a gas turbine combustion system having reduced emissions and improved flame stability at multiple load conditions is disclosed. The improved combustion system accomplishes this through complete premixing, a plurality of fuel injector locations, combustor geometry, and precise three dimensional staging between fuel injectors. Axial, radial, and circumferential fuel staging is utilized including fuel injection proximate air swirlers. Furthermore, strong recirculation zones are established proximate the introduction of fuel and air premixture from different stages to the combustion zone. Fuel injection staging sequences are disclosed that create the conditions necessary to provide stable combustion and reduced emissions at multiple load conditions.

  • Patent number: 6986255
    Abstract: A fuel injector system that reduces and/or eliminates combustion instability. The fuel injector system includes a pilot fuel injector, a pilot swirler that swirls air past the pilot fuel injector, a main airblast fuel injector having an aft end, inner and outer main swirlers that swirl air past the main airblast fuel injector, and an air splitter located between the pilot swirler and the inner main swirler. The air splitter includes at least one aft end cone angled radially outboard and axially positioned downstream of the main airblast fuel injector aft end. The air splitter divides a pilot air stream exiting the pilot swirler from an inner main air stream exiting the inner main swirler to create a bifurcated recirculation zone.

  • Patent number: 6986257
    Abstract: A method enables a gas turbine engine to be operated. The method includes directing fluid flow from a source into an inlet of a valve, channeling the fluid flow entering an inlet portion of the valve towards an outlet portion of the valve such that a direction of the fluid flow is changed within the inlet portion, and controlling the amount of fluid flow entering the outlet portion of the valve by selectively positioning a valve disk coupled within the inlet portion of the valve by a valve disk axle. The method also comprises channeling the fluid flow from the inlet portion of the valve through the outlet portion of the valve and into a fluid supply pipe, wherein the valve outlet portion has a substantially right cylindrical shape such that a direction of fluid entering the body outlet portion remains substantially constant therethrough.
