  • Patent number: 10493311
    Abstract: Improvements in an exercise machine where the fan blades alter the resistance created by the blades or vanes by moving a cone that pushes the blades out from a central position. The blades or vanes push against the cone with springs. The cone is then moved into or out of the central axle to alter the effective diameter of the blades or vanes. A twist or contouring of the blades or vanes can be obtained at the same time to alter the resistance. In another embodiment, the fan blades can be individually or collectively adjusted to change the resistance. As the diameter is increased the speed of the blade tips increases as a squared function of the radius without changing the rotational speed of the vane(s). The shape, angle, scoop or tilt of the blade or vanes can also be altered to change the resistance.

  • Patent number: 9551186
    Abstract: Systems, methods, and devices are provided to generate a stable supply of electrical power in a drill string. In one example, a downhole turbine generator includes a turbine, a speed governor, and an alternator. The turbine may transform hydraulic power of a first fluid medium into rotational power of a rotating shaft. The speed governor may reduce the rotational power of the rotating shaft in a variable amount that depends on the speed of the rotating shaft. Specifically, weighted arms may shear a second fluid medium more when the speed is higher and less when the speed is lower. The shearing of the second fluid medium may generate a countervailing torque on the rotating shaft to reduce the rotational power of the rotating shaft. The alternator then may produce a generally stable supply of electrical power from the rotational power of the rotating shaft.

  • Publication number: 20100129193
    Abstract: Smooth, preferably variable-sweep fluid collection device surfaces disposed into opposition with wind, river, surf, ocean or tidal currents generate enhanced velocity fluid flows at length driven into onboard work-extracting disc turbines at advantageous angles of attack. Keyed to shafts turning freely through optionally extendable volutes, disc turbines comprising a dense population of smooth, axially fixed or adjustably spaced discs conducting preferably laminar flow between adjacent elements develop significant torque through boundary layer adhesion and viscous shear-stress between fluid layers. Exhaust of disc turbine throughput into divergent channels drafting into external currents of initially higher than ambient velocity and lower pressure may reduce turbine discharge backpressure, rapidly clear system throughput, and allow normally disadvantageous drag to be utilized to develop greater work generation.

Four sails (10) are joined in oppositely disposed pairs and communicate by cables (16) through guides (18) that are positioned on a square rotor hub (14) and control the shape of the linked sails. When acted upon by wind, the sails reciprocally open and close to form two shapes. The two shapes are a scoop and a wing. The scoop holds the wind when receding from the wind. The advancing sail forms a wing that rides the wind promoting stability and reducing friction in the rotor wheel. The action of the advancing sail dampens the sail action of the opening sail and limits the opening sail to a preferred scoop shape.

  • Patent number: 5549445
    Abstract: A process and system for harvesting energy from wind action on the high seas ill all weather conditions, on a year-round basis. This process depends upon the use of seagoing platforms (FIG. 2+ FIG. 4) which themselves achieve stability in the presence of storms at sea, doing so through the selective extraction of wave energy. The selective wave energy extraction takes place in such a way that the prevailing ratio of sea height to swell height affecting a typical seagoing platform ((FIG. 2 or FIG. 4)) is reduced to a small fraction of the ratio of sea height to swell height which prevails at a distance from the platform. In short, this process and system stabilizes a plurality of seagoing platforms which support wind and wave energy conversion means, while simultaneously extracting and converting energy from the combined wind and wave action.

    Abstract: A vehicle compressed air energy converter has been developed for use along vehicular roadways, railways and airfield runways to collect wind pressure developed by the vehicles, trains and aircraft moving through the atmosphere and convert such air motion to other useful forms of energy. The converter is activated by the force of the compressed air movement entering the converter and pushing the retractable air fins of the converter in a circular motion. That circular motion is transferred to a central shaft set in bearings at either end of a housing. As the multiplicity of air fins held in place by hinges on a circular rotating base move within the converter housing, the fins move into a retracted posture so as to offer less air resistance as they circulate within the portion of the converter not subject to movement of air from the exterior of the housing.

The turbine includes a disc, mounted on a shaft located in central guides affixed to an outer stationary turbine stand. The disc mounts a plurality air blade shaped in such a way that the incoming air impinges on the blades radially, circumferentially and outwardly relative to the turbine disc.

  • Patent number: 4872804
    Abstract: A device for generating power from wind which includes a shaft extending in a longitudinal direction and propelling elements mounted on the shaft. The shaft is mounted for rotation in a frame which is also mounted for rotation. The device also includes a deflector on the frame for deflecting wind into the propelling elements by orienting the frame due to rotation thereof to have a portion thereof facing the direction of travel of the wind. The deflector also increases the force of the wind on the propelling elements by compressing the wind and further deflects the wind to strike the propelling elements at a position radially outwardly of the shaft and radially inwardly of an outer periphery of the frame. The deflector further prevents the wind from striking the propelling elements along a part of the outer periphery of the frame which faces the wind direction.

  • Patent number: 4838757
    Abstract: The present invention relates to a combination of a Savonius type rotor (20) and a deflector plate device (101) which serves as an augmentation apparatus which considerably increases the power output of the Savonius type rotor and also improves its self-starting ability and smoothness of operation. The invention also describes a novel Savonius type rotor (20) of greater efficiency than existing Savonius type rotors. In connection with the rotor-deflector combination, the present invention also teaches a simple, automatic speed control mechanism (107) which additionally can be used to facilitate stopping the rotor if desired.

  • Patent number: 4213735
    Abstract: A high pressure centrifugal pump has an impeller assembly including two mating impeller sections which are each constituted by a shroud with fixed geometry blades. The impeller sections are fixedly mounted upon a rotatable shaft and are of a construction which permits the pressure between the impeller sections to engender flexure of the sections away from each other so as to vary the breadth of the impeller assembly. A servo control device is adapted to control the pressure behind the shrouds such that the pump delivers a constant flow at varying back pressures.
