  • Patent number: 10543915
    Abstract: A propeller assembly includes propeller blades that self-fold when not in use, which reduces the overall footprint of the propeller assembly and enables efficient storage. During flying conditions, the propeller blades unfold and extend to a flight configuration that enables the generation of lift on the propeller blades and consequently to an attached aerial vehicle. In various embodiments, the transitioning of the propeller blades between a flight and folded configuration may be enabled by torsion springs coupled to each propeller blade. For example, the torsion springs cause each propeller blade to rotate and self-fold when no external forces are applied. Alternatively, during flying conditions, centrifugal forces that arise as the propeller assembly rotates counteract the torsion springs, enabling each propeller blade to achieve an extended flight configuration. Therefore, the propeller blades of the propeller assembly are optimally oriented without the need for human intervention.

  • Patent number: 7448221
    Abstract: A turbine engine has a first disk and a second disk, each extending radially from an inner aperture to an outer periphery. A coupling, transmits a torque and a longitudinal compressive force between the first and second disks. The coupling has first means for transmitting a majority of the torque and second means, radially outboard of the first means, for transmitting a majority of the force.

  • Patent number: 7270513
    Abstract: Apparatus for generating power from a water current in a body of water comprises a longitudinally extending flotation platform for maintaining the apparatus afloat in the body of water and a water turbine operatively carried by the platform for generating power in response to water current in the body of water. The platform is configured to enhance the flow of water current over the turbine blades and, as well, to enable a number of like platforms each with an associated turbine or turbines to be arrayed in a cooperative manner. The water turbine may comprise a turbine rotor with a plurality of relatively narrow, flexible elongated blades arranged in circumferentially spaced rows extending along the rotor. In each row, the blades are distanced from each other in succession by a space.

  • Publication number: 20070177972
    Abstract: This invention relates to a Dry Running Flexible Impeller Pump and Method of Manufacture that is specifically designed to provide a flexible impeller pump that is capable of being run dry for extended periods of time without damaging the impeller. The pump's housing and end plates are coated with a low friction industrial coating to limit the heat of friction created by the flexible impeller while in use. Additionally the flexible impeller is cast from a pre-molding silicone substrate that contains no mold release and is cast in a mold that is treated with a low friction industrial coating and is cast without mold release. Once the flexible impeller is removed from the mold it is cleaned with alcohol, baked in a vacuum at a temperature of at least 100° C., and then coated with a Paralene N coating by vacuum deposition.

  • Patent number: 7014417
    Abstract: A hybrid pump (1) with a housing (2) comprising at least one suction port (10) and at least one pressure port (11). A rotor (5) is eccentrically arranged in the housing chamber (3) which is substantially enclosed in a circular manner. The rotor (5) has a plurality of circumferentially spaced vanes (6) which are radially arranged at least in some segments and are made of a material that is resiliently deformable under centrifugal force. The eccentricity (14) of the rotor (5) in relation to the housing chamber (3) and the elasticity of the rotor vane (6) are such that in a first phase of low rotational speed, the radially distant end areas (7) of each vane (6) touch only some or no circumferential segments (4) of the housing chamber (3) in the course of one rotor (5) rotation, whereas in a second phase of higher rotational speed, the radially distant end areas (7) of all vanes (6) touch the inner wall (4) of the housing chamber (3) essentially during the entire rotor (5) rotation.

  • Patent number: 6877968
    Abstract: A low head water turbine comprising a runner having a cylindrical outer surface and a plurality of similar blades similarly pivotably secured along their inner sides to the outer surface of the runner so as to pivot in the direction of rotation of the runner between a closed position lying adjacent the outer surface of the runner and an open position at an angle thereto. A housing having end walls and a rounded side wall extending therebetween, completely encases the runner and its blades. The runner is eccentrically mounted to end walls of the housing for rotation about a horizontal axis so that the cylindrical outer surface is spaced closer to an upper portion of the housing side wall and farther from a lower portion. A water inlet opening is located in a lower, forward portion of the housing, below the axis of rotation of the runner. A water outlet opening is located in a lower, rearward portion of the housing.

    Abstract: A low head water turbine comprising a runner having a cylindrical outer surface extending between opposite ends and a plurality of similar blades having inner and outer sides extending to ends. The blades are evenly spaced about the surface of the runner and extend to the ends of the runner. The blades are similarly pivotably secured along their inner sides to the outer surface of the runner so as to pivot in the direction of rotation of the runner between closed position lying adjacent the outer surface of the runner and open position at an angle thereto. A housing having end walls and a rounded side wall extending therebetween, completely encases the runner and its blades. End walls of the housing are proximal to the ends of the runner. The runner is eccentrically mounted to the end walls of the housing for rotation about a horizontal axis so that the cylindrical outer surface of the runner is spaced closer to an upper portion of the housing side wall and farther from a lower portion.
