  • Patent number: 6408627
    Abstract: A continuous power system accumulator assembly is provided that stores thermal energy as sensible heat and minimizes the amount of thermal energy wasted by the system. The assembly includes an accumulator at its core. A preheater assembly is wrapped around the accumulator such that it may absorb heat radiated and conducted from the accumulator. An evaporator is wrapped around the preheater so that most of the heat that is radiated and conducted from the preheater is utilized to heat the vaporizer. The outer housing of the assembly may be a double-walled housing having a layer of insulation located between the two walls. This configuration minimizes heat losses by the assembly.

  • Patent number: 5706647
    Abstract: Past airfoil configurations have been used to improve aerodynamic performance and engine efficiencies. The present airfoil configuration further increases component life and reduces maintenance by reducing internal stress within the airfoil itself. The airfoil includes a chord and a span. Each of the chord and the span has a bow being summed to form a generally "C" configuration of the airfoil. The generally "C" configuration includes a compound bow in which internal stresses resulting from a thermal temperature gradient are reduced. The structural configuration reduces internal stresses resulting from thermal expansion.

  • Patent number: 5653580
    Abstract: The present nozzle and shroud assembly mounting structure configuration increases component life and reduces maintenance by reducing internal stress between the mounting structure having a preestablished rate of thermal expansion and the nozzle and shroud assembly having a preestablished rate of thermal expansion being less than that of the mounting structure. The mounting structure includes an outer sealing portion forming a cradling member in which an annular ring member is slidably positioned. The mounting structure further includes an inner mounting portion to which a hooked end of the nozzle and shroud assembly is attached. As the inner mounting portion expands and contracts, the nozzle and shroud assembly slidably moves within the outer sealing portion.

  • Patent number: 5580219
    Abstract: A turbine blade having a preestablished rate of thermal expansion is attached to a turbine flange having a preestablished rate of thermal expansion being greater than the preestablished rate of thermal expansion of the turbine blade. The turbine flange includes a first upstanding flange and a second upstanding flange having a groove formed therebetween. The turbine flange further includes a recess. Each of the first and second upstanding flanges have a plurality of bores therein. A turbine blade has a first member and a second member positioned in one of the groove and the recess. Each of the first member and the second member have a plurality of bores therein. And, a pin is positioned in respective ones of the plurality of bores in the first and second upstanding members and the first and second members and attach the blade to the turbine flange. The pin has a preestablished rate of thermal expansion being substantially equal to the rate of thermal expansion of the blade.

  • Patent number: 4942944
    Abstract: Apparatus to lubricate generator bearings with an oil-air mist is disclosed. A screw pump, preferably an assembly of components comprising a ring, a teflon seal, a pump rotor and a hub is secured onto a rotor shaft of a generator for rotation therewith. The rotor shaft has at least one passageway extending radially from an axial bore therein through which oil is transferred. The screw pump has a first orifice coincident with the rotor shaft passageway, a second orifice, a passageway extending from the first orifice to the second orifice through which the oil is directed into a cavity in the generator housing where it mixes with air to form a mist to lubricate the bearing, a circumferential surface fitting within an opening in the generator housing, and a helical groove in the circumferential surface through which the oil-air mist is evacuated during rotation of the generator rotor shaft.
