Abstract: A method and apparatus for the pressurizing of fluids within a rotating rotor wherein a fluid enters the rotor near center, is first pressurized by centrifugal force with initial acceleration and is then further accelerated and pressurized within a circular cavity in a free vortex. The fluid then leaves the circular cavity via openings at periphery and is passed inwardly toward rotor center via passages, and discharged via opening near rotor center. Fluids may be gases or liquids. The device can be used either as a pump, a compressor, or a turbine as desired.

Abstract: A pressurized gas engine with an axially rotatable rotor having aerodynamically smooth exterior and interior fluid flow surfaces and a central opening in one of a pair of end walls that define with a peripherally circular border wall a hollow interior. The rotor includes energy conversion means that convert fluid pressure energy into mechanical energy of rotation with the conversion means including a plurality of nozzles in and spaced around the border wall and exhausting rearwardly of the direction of rotation. The rotor is enclosed in a casing that is spaced from the rotor at the areas traversed by the nozzles a distance sufficient that the exhaust fluid within the casing does not serve as a drag or brake on the rotating rotor so that the engine attains high speeds in an efficient manner. The disclosure also includes the fact that the total area of the entrance opening means to the rotor is greater than the total area of the exit opening means with the preferred ratio being about 2 to 1.

Abstract: A device for destratifying bodies of water for controlling water quality parameters. The device includes an elongated hollow shroud within a cylindrical pipe that is capable of being supported in a vertical position within the body of water. The shroud is mounted on a center hollow drive shaft. A reactive propulsion driven rotary arm disposed in the plenum of the shroud is driven by pressurized fluid. Within the pipe, but outside of and near the lower end of the shroud's drive shaft, an impeller forces water upwardly and axially around the shroud to the water's surface. The reactive propulsion means is preferably driven by pumped air, whereby the effect of the pressurized air rotates the arm and the impeller fixed to the common drive shaft. This action aids in destratifying the body of water. A series of guide vane blades may be interposed on the same drive shaft between the impeller and the shroud to reduce the turbulence of the water exiting from the impeller.

Abstract: A method and apparatus for the generation of high velocity fluid jets by using a rotor with attached discharge passages and nozzles. A working fluid is accelerated by using a rotating rotor, either of the free vortex type or of the forced vortex type, and the accelerated fluid is then passed through forwardly and inwardly extending passages, and discharged at high speed through openings that are inward from the rotor periphery. Fluids may be either liquids or gases. The high velocity fluid jet may be used where such jets are required, such as excavation, cutting, or as a source of thrust. The rotors may be also made multistage, if additional jet velocity is required.

Abstract: Apparatus to convert the internal energy of hot fluids to mechanical work comprising a pair of nozzles, e.g. convergent-divergent nozzles, mounted oppositely on hollow support arms which are in turn mounted on a rotating hollow shaft which is coupled to a conventional electric generator or other device requiring mechanical power. The hot liquid, e.g. hot brine, flows through the hollow shaft and the hollow support arms to the nozzles, where the hot fluid expands and creates a thrust and torque on the shaft, causing it to rotate and create shaft power. The nozzles and rotating shaft are mounted in a closed container from which the exhaust fluid, gases and liquid are removed by conventional means so as to maintain a reduced pressure within the container.

Abstract: A method and apparatus for generating power and for pumping fluids, wherein a free vortex cavity, within a rotating rotor, is used to pressurize a fluid after which the fluid may be used as a pressurized fluid or be used to generate power. The working fluid is injected into the free vortex cavity through feed nozzles oriented to discharge the working fluid forwardly in the direction of rotation, so that the working fluid rotational speed is normally, at least in part of the cavity, greater than the rotational speed of the rotor. The working fluid is pressurized within the vortex cavity by being forced to follow a curved path. Part of the working fluid is taken near the periphery of the curved passage, and recirculated through nozzles located toward the rotor center from the periphery thus providing additional fluid flow within the free vortex cavity and improving the rotor performance.

Abstract: A method and apparatus for the pressurizing of fluids wherein a rotor is rotated on a shaft and the rotor is provided with an entry for the fluid at center, a pressurizing cavity with vanes, nozzles discharging the fluid forward, a vortex cavity for pressurizing the fluid, and exit means for passing the fluid from the rotor. Usually a casing is provided for collecting the pressurized fluid with an exit for delivery. The pressurizer can be used to pressurize either liquids or gases. The exit means from the rotor may be nozzles directed to discharge the fluid, or they may be other means for reclaiming part of the kinetic energy of the leaving fluid.

Abstract: A pressure gas engine in which pressurized gas such as air is supplied to a series of arcuately arranged nozzles for exhausting into a series of arcuately arranged impulse buckets thereby causing rotation of a rotor in which the buckets are located, each nozzle having an exit adjacent the buckets and each bucket having a curved surface with an entering boundary edge and a leaving boundary edge for the gas blast leaving the bucket so that the blast sweeps across the curved surface of each bucket. The exit diameter of each nozzle is less than the radius of the curved surface of each bucket to achieve a full sweep of each bucket's curved surface from the entering edge to the leaving edge.

Abstract: A turbine type air motor including a rotor and driven spindle having automatic speed regulation. The spindle and rotor have cooperating ports to control the flow of air to the rotor, and the spindle has provision for limited twisting movement within the rotor for moving the ports into and out of register. A biasing spring interposed between the spindle and rotor urges the ports normally out of register when the tool is lightly loaded. An increase in the load imposed upon the spindle causes the spindle to retreat relative to the rotor and against the force of the spring to bring the ports into register, thereby to increase the flow of air so that the torque developed by the rotor increases in step with the torque loading imposed on the spindle to maintain speed. In the preferred embodiment the spindle is of hollow construction and compressed air is fed axially into the hollow for transmission into the rotor through radial ports.

Abstract: A method and apparatus for generating power by passing a fluid from a higher energy level to a lower energy level by compressing said fluid first in a continuous flow centrifuge rotor and then reducing the pressure of said fluid in an inward flow reaction turbine section. The fluid enters the first rotor at center and leaves the second rotor at center, and vanes are provided within both rotors to assure that said fluid will rotate with said rotors. Nozzles are provided near the periphery of the first rotor to increase the absolute tangential velocity of the fluid leaving said first rotor; the tangential velocity of second rotor near rotor tip is greater than said first rotor tangential tip velocity. The said fluid is contained within said rotors, and passes from said second rotor to said first rotor near rotor center.
