  • Patent number: 8544765
    Abstract: A solid stream nozzle providing an extend throw-distance achieved by reducing boundary layer effects within the nozzle bore and/or by accelerating peripheral regions of the ejected stream in order to help maintain cohesion of a free liquid stream without appreciable dispersion. The method includes generating a high-pressure fluid source, supplying the nozzle with high pressure; reducing boundary layer effect within the nozzle bore, and optionally, accelerating and/or inwardly re-directing the peripheral boundary of the ejected stream with a secondary higher pressure, higher speed fluid source. The apparatus includes a high pressure fluid source, a nozzle bore, a bleed ring within the nozzle bore to strip off a boundary layer, and optionally, a secondary higher pressure fluid source at the nozzle tip to accelerate and/or inwardly re-direct the ejected fluid stream.

  • Patent number: 7978078
    Abstract: A magnetic core transceiver antenna for EAS marker detection is provided. The core includes a stack of amorphous alloy ribbons insulated from each other and laminated together. A coil winding of wire, also insulted from the ribbons, and connected to an electronic controller provides the transmitter and receiver modes. The transceiver antenna is optimized for the dual mode operation, and is smaller and uses less power than conventional air-core EAS antennas with equivalent performance. Complex core geometries, such as a sandwiched stack of different sized ribbons, can be implemented to vary the effective permeability of the core to customize antenna performance. Multiple transceiver antennas can be combined to increase the size of the generated EAS interrogation zone.

  • Patent number: 5911679
    Abstract: A cospander for extending the high efficiency range of a turbine engine is described. A cospander, in one aspect, is a turbomachinery device including at least one stage wherein stator vane and rotor blade rows are continuously variable to an extent that each stage can be operated in compression, expansion, or null modes depending on the blade and vane angles at any specific operating point. Such a device placed ahead or within a typical compressor has the effect of reducing, increasing, or maintaining the through flow of the primary working fluid. Such flow variation control can be used to achieve the desired overall turbomachinery thermal efficiency improvements over a wider operating range than is otherwise possible. In one specific embodiment, for example, the cospander includes a variable stator vane and a variable pitch rotor blade in series flow relationship.

  • Patent number: 5553448
    Abstract: A gas turbine engine having improved output horsepower and a method of achieving it. The engine has, in order, a low pressure compressor, a high pressure compressor, a combustor, a high pressure turbine and a low pressure turbine. The high pressure turbine is drivingly connected to both compressors with a speed reducing gear box therebetween. An intercooler between the compressors reduces the horsepower requirement of the high pressure compressor. Flow from the combustor is sufficiently heated to enable the high pressure turbine to drive both compressors with the output horsepower of the low pressure turbine devoted to the engine load.

  • Patent number: 5521609
    Abstract: A lightweight search-coil antenna or sensor assembly for detecting magnetic fields and including a multi-turn electromagnetic induction coil wound on a spool type coil form through which is inserted an elongated coil loading member comprised of metallic glass material wrapped around a dielectric rod. The dielectric rod consists of a plastic or a wooden dowel having a length which is relatively larger than its thickness so as to provide a large length-to-diameter ratio. A tri-axial configuration includes a housing in which is located three substantially identical mutually orthogonal electromagnetic induction coil assemblies of the type described above wherein each of the assemblies include an electromagnetic coil wound on a dielectric spool with an elongated metallic glass coil loading member projecting therethrough.

  • Patent number: 5160080
    Abstract: A method of operating a gas turbine engine includes providing combustion gases to turbine means, and choking flow of the combustion gases for increasing shaft horsepower in an output shaft while reducing thermal efficiency of the gas turbine engine. The method may also include the step of supercharging the turbine means for further increasing output shaft horsepower. In accordance with an exemplary embodiment, a gas turbine engine effective for carrying out the method is disclosed. The engine includes an output shaft, compression means, combustion means, turbine means, and diffusion means for diffusing combustion gases discharged from the turbine means for obtaining choked flow for increasing shaft horsepower and reducing thermal efficiency. The compression means is effective for supercharging the turbine means at a predetermined speed of the output shaft for providing increased output shaft horsepower.

  • Patent number: 5150567
    Abstract: A powerplant comprising a first compressor for producing a downstream axial flow, a second compressor positioned downstream of the first compressor and combustor positioned downstream of the second compressor. A first turbine is positioned downstream of the combustor and the first turbine is drivingly connected to the second compressor through a first shaft. A second turbine is positioned downstream of the first turbine and the second turbine is drivingly connected to the first compressor through a second shaft. The powerplant is connected to a load which is primarily rotary as opposed to a downstream axial thrust and the load is coupled to the second shaft. Further the invention includes a method of converting an aircraft turbofan engine having a fan, and a compressor for producing a downstream flow adjacent the fan, to a non-aeronautical application comprising the steps of removing a fan from a shaft of the engine and attaching a connection for attaching a load to the shaft from which the fan is removed.

  • Patent number: 4785621
    Abstract: In a coal gasification plant there is a requirement for supplying oxygen to the coal gasifier in order to produce coal gas fuel. An oxygen plant will produce oxygen and nitrogen from an input supply of compressed air. In the presence of a fired gas turbine which is supplied with coal gas fuel, the waste heat from the fired gas turbine may be used to heat compressed air for driving an air cycle turbine. The air cycle turbine in turn drives an air cycle compressor for producing air to the oxygen plant. The nitrogen gas by-product from the oxygen plant is injected into the air cycle for disposal through the air turbine.

  • Patent number: 4785634
    Abstract: The use of hot gas generators which produce corrosive or abrasive products of combustion have precluded the use of gas turbines in a direct flow path of the combustion products. It is preferable to utilize non-contact gas to gas heat exchangers in order to transfer heat from a hot gas stream to a working fluid. A first heat exchanger connected to a gas furnace is used to raise the temperature of an air turbine inlet gas. A second heat exchanger is used to raise the temperature (prewarm) of compressor discharge air to the air turbine air inlet, the second heat exchanger connected to the air turbine exhaust. A third heat exchanger preheats the air input into a furnace.

  • Patent number: 4751814
    Abstract: An air cycle thermodynamic conversion system compresses a compressible gas in a multi-stage compression process with intercoolers between each adjacent pair of compressors. The intercoolers return the compressed gas temperature to about ambient temperature before each succeeding compression operation. The compressed gas is heated in a heat exchanger passing a heated exhaust gas in counterflow with the compressed gas to increase the thermal energy of thereof. A minimum temperature gradient is maintained between the heating compressed gas and the cooling exhaust gas by establishing the two flows such that they both have about equal heat capacities. The heated compressed gas is expanded in a turbine to produce at least enough torque to drive the multi-stage compression system. Additional torque may be produced in the turbine for driving a using process. Alternatively, an excess of heated gas, beyond that required for driving the turbine, may be fed directly to a using process.
