The turbine runner also includes a conical-shaped hub rotatable about a central axis, the hub having a diameter that decreases in size from the inlet to the outlet, the conical-shaped hub including a base having a circumference adjacent the inlet and a surface sloping inwardly toward the central axis, the surface including a concave section facing the inlet when viewed in the meridional cross-section. The turbine runner also includes at least two helical turbine blades connected to the conical-shaped hub, each turbine blade having a leading edge adjacent to the inlet, a trailing edge adjacent to the outlet, a blade running length therebetween having a pitch, each turbine blade further including an outer edge, wherein each turbine blade winds at least halfway around the conical-shaped hub.

Abstract: An apparatus for supplying high pressure atomizing and purging fluid to the fuel system of a gas turbine engine. The apparatus is comprised of a turbocompressor, multiple flow conduits and associated valves and controls. Alternative versions of the fundamental apparatus may include heat exchangers for heating and cooling the atomizing and purging fluid within the apparatus. The apparatus works with all types of gas turbine engine cycles well known to one skilled in the art. The apparatus includes a first conduit for extracting a small percentage of the fluid compressed by the turbine engine compressor, and the first conduit is further divided into second and third conduits for supplying portions of the small percentage of compressed fluid to the turbocompressor compressor and turbine.

Abstract: A fuel and air mixing apparatus for a combustor and gas turbine generator. A primary portion of the fuel is injected into the mixing air at long distances from the combustor prechamber. The primary portion of the fuel is almost completely mixed with the mixing air. A secondary portion of fuel is injected into the mixing air in the boundary layer at a short distance form the combustor prechamber. This minimally mixed second portion provides some rich portions of fuel-air in the prechamber to improve stability and reduce the chances of blowout.

Abstract: A flow measuring or flow metering device having a dynamically variable inner diameter. The flow device uses electrorheological fluid to support an inner flexible membrane. The quantity of electrorheological fluid is varied to change the inner diameter of the flexible membrane.

Abstract: An inlet air cooling system for natural gas compression. The system provides both inlet air refrigeration for the internal combustion engine and additional natural gas compression. Also provided is a leakage control system for any natural gas or hydrocarbon leakage from the combined cycle system. The leakage is collected and introduced into a low pressure portion of the engine air intake system where it is burned along with the normal engine fuel.

Abstract: A centrifugal impeller includes a hub formed about an axis of rotation with a plurality of substantially radially extending blades affixed to the hub, each blade having a suction surface, and a pressure surface formed on the adjacent blade facing the suction surface. The blades have a height being measured in a radial direction from the hub. A portion of the hub, having a hub configuration, extends between the pressure surface and the suction surface. An imaginary plane extending in a direction normal to the axis of rotation is used to define a cross-sectional view of the impeller. A first and a second concentric circle are formed in the plane with the center of the concentric circles being the axis of rotation. The first circle passes through a point on the hub located closest to the axis of rotation. The second circle has a radius greater than the first circle by an amount equal to five percent of the blade height, wherein a portion of the hub extends outside of the second circle.

Abstract: A compressed air driven hand-held tool including a body adapted to be grasped by the hand, an air inlet adapted to be connected to an air supply hose, an air motor driving an output shaft carrying a work implement, and a throttle valve controlling the supply of air to the motor. A spring acts on a valve piston to urge the throttle valve to a closed position. The piston is acted on by air pressure to allow the throttle valve to open. A control chamber in the tool body receives air pressure from the air supply through a restricting orifice at a controlled rate, has an air outlet adapted to closed by the hand of the operator when grasping the tool body and is connected to the air pressure side of the valve piston. When uncovered, the air outlet exhausts the air in the control chamber at a rate to maintain the pressure in the control chamber at an atmospheric level. When covered by the operator's hand, the air pressure in the control chamber rises and acts on the valve piston to open the throttle valve.

Abstract: A method for determining a smooth machining course for a cutting tool during machining of a workpiece. Each possible cutting tool position, with respect to the workpiece, is defined by a separate reference vector. A progression of points are defined as a tool path. A first specified portion of the reference vector will follow the tool path during machining of the workpiece. A series of reference planes are generated, each plane defines a planar set of all possible reference vector positions for each point. An acceptable range from eahc set is established which defines acceptable reference vector positions within each plane for each point. A tool course is generated, which will be followed by a second portion, distant from the first portion, of the reference vector utilizing an algorithm to minimize irregularities of the course, and to contain the course entirely within the acceptable range.

Abstract: In the embodiment depicted, the dynamometer is of an absorption type, for fluid, having fluid entries on both axial ends thereof, and a rotor having blades disposed, in a radial exit flow path, in parallel with the rotor axis. Adjustable, annular, blade shrouds, controlled simultaneously, expose more or less of the blade lengths to the radial exit fluid flow path.

Abstract: A depicted embodiment of the apparatus comprises a housing having a chamber therewithin and a pair of ports opening into the chamber. One port admits an energized gas, and the other admits a particulate powder, into the chamber. Tubes conduct the powder through the chamber, isolated from the energized gas, to exit ends of the tubes which have convergent/divergent ejector nozzles circumjacent thereto. The ejector nozzles discharge the gas therethrough in fine streams, to draw powder from the tube exit ends for conveyance with the gas streams, and direct the streams of gas and powder to adjacent and collinear diffusers for dispersion of the gas-borne powder from the apparatus.

Abstract: The invention is a smoke generator which atomizes fog oil by means of a slinger disc affixed to, and rotating with, a turbine wheel. The atomized fog oil mixes with, and is evaporated by, the hot, turbine exhaust gas. Upon leaving the generator, the evaporated fog oil recondenses into a smoke cloud. The smoke cloud generated is to provide a visual screen on a battlefield for concealing the whereabouts of troops and equipment from observance by an enemy.

Abstract: The valve, according to the illustrated embodiment, comprises an annular chamber formed of concentric inner and outer walls, the outer wall having, in the periphery thereof, a multiplicity of equally spaced apart rectangular slots. An annulus, having a corresponding multiplicity of slots, is rotatably journalled, concentrically, on the outer periphery of the outer wall in order that, upon rotation thereof, relative to the annular chamber, the slots in the wall, and those in the annulus, come into or out of registry. A crank mechanism is coupled between the annulus, and the structure defining the annular chamber, to selectively rotate the annulus through a limited arc to bring the slots into and out of such registry. The valve is used to throttle the velocity of compressed gas product conducted thereto by a gas compressor, and to subdivide compressed gas issuing therefrom into a multiplicity of fine jets.
