  • Patent number: 11761426
    Abstract: A zero-fossil-fuel-using non-polluting apparatus to (1) use wind power to (2) generate a steady flow of hydroelectricity (3) from increasing the height level of water from a water table or river or lake and (4) storing that water and its potential energy in (5) a water tower, and then (6) releasing that water's potential energy in a (7) steady gravity-driven flow in a downward-flowing pipeline to (8) operate in-pipe electricity generators to establish a reliable non-fluctuating source of hydroelectricity from (9) many in-pipe hydroelectricity generators in pipelines to create electricity when the water tower water is released to the in-pipe hydroelectricity generators which creates (10) a steady non-fluctuating stream of water to turn the turbines of many in-pipe hydroelectric generators to create (11) a steady, non-fluctuating flow of electricity regardless of whether the wind is blowing or the sun is shining.

  • Patent number: 11060539
    Abstract: A device having a hybrid hydraulic-electric architecture includes a hydraulic pump/motor having first and second ports, and an electric motor. The device is configured to connect to two or more pressure rails, each pressure rail containing hydraulic fluid at a different pressure than the other pressure rails. A flow of hydraulic fluid from one of the pressure rails is driven through the hydraulic pump/motor, and a pressure difference exists between the first and second ports. The electric motor is configured to control a flow rate of the flow of hydraulic fluid and/or the pressure difference.

  • Patent number: 11009006
    Abstract: A wind turbine may include a discoidal chassis and at least one vane disposed on the discoidal chassis. The discoidal chassis can rotate about a central axis. The discoidal chassis has a first outermost surface with a pitch angle between the central axis and another axis orthogonal to the central axis. The vane is disposed on the first outermost surface. The vane has a concave surface to assist in rotation of the discoidal chassis about the central axis by harnessing wind energy.

  • Patent number: 10428793
    Abstract: The present disclosure refers to a rotor (1) comprising a rotor blade (3), a hub (2), on which the rotor blade (3) is held by means of a bearing, and an adjustment device (7, 8, 10), in which a coupling component (7) arranged at the foot (5) of the rotor blade (3) is mounted in a guide (10) arranged on an adjustment component (8), such that by means of a displacement of the adjustment component (8) axially with respect to the axis of rotation (11) of the rotor of the hub (2) a pitch angle of the rotor blade can be altered, wherein the guide (10) runs at an inclination to the axis of rotation (11) of the rotor, at least during the axial displacement of the adjustment component (8). Also disclosed is a method for adjusting a pitch angle of a rotor blade.

  • Patent number: 8731726
    Abstract: A method is provided for regulating fluid pump pressures by detecting an elevation differential between a fluid flow control device and the distal end of a fluid line in communication with the fluid flow control device. A fluid flow control device, for instance a peritoneal dialysis device, is at a first height, a distal end of a fluid line is at a second height, and a valved outlet, when open, affords communication between the fluid flow control device and the distal end of the fluid line. The elevation differential is correlatable with a pressure measurable during a calibration procedure provided as a part of the methodology.

  • Patent number: 5174724
    Abstract: Disclosed is a two cylinder water well pumping system which uses the wind as a primary driving force with an alternate electric motor drive for use when the wind force is not adequate. The wind drives a square wheel turbine which in turn drives a swash plate which provides a cam surface which then drives a semaphore assembly directly or indirectly connected to sucker cables in turn connected to two pistons carried, respectively, in two cylinder sleeves. The inclined angle of the swash plate alternately drives the pistons to pump water from a well into a storage tank also serving as a mainmast supporting said turbine. In an alterenative embodiment, an electric motor is connected to drive an osillatable bar on a mechancial relay. The oscillatable bar is connected by cables to the semaphore assembly, and may be disconnected from the semaphore assembly by a solenoid. In this embodiment, the sucker cables are connected to the rockable bar in the mechanical relay rather than to the semaphore assembly.

  • Patent number: 4498017
    Abstract: A wind machine turns a shaft to activate a multi-stage positive displacement pump having intake and discharge means respectively coupled to intake and discharge fluid lines in a recirculating hydraulic system. Control means regulates the operative positions of the intake means, discharge means or separate idling means to remove selected stages from effective pumping while at the same time fluid passes into and from the selected stages. The stages can be of different capacities and selected groups or all of them may be periodically idled by a common or individual idling means. Constricting means is located in the common discharge line from all stages and can be additionally located in each discharge line from each stage.

  • Patent number: 4496846
    Abstract: A wind machine turns a shaft to activate a multistage pump having intake and discharge means respectively coupled to intake and discharge fluid lines. Idling means is provided for each stage and constricting means is located in series with each stage between the intake and the discharge lines. Control means regulates the idling means and constricting means to remove selected stages from effective pumping while at the same time fluid passes into or from the selected stage. Pressure in the fluid discharge line is retained substantially constant without the need for energy accumulation and at the same time the torque on the shaft can be adjusted to retain the shaft speed in a range for effective wind energy conversion. During starting the constricting means is closed while the idling means opens until an operational speed is reached. Power assisted starting is achieved by initially reversing the fluid flow through selected stages.

Control means regulates the operative positions of the intake means or discharge means to remove selected stages from effective pumping while at the same time fluid passes into and from the selected stages. The stages can be of different capacities and selected groups or all of them may be periodically sequentially idled. Torque on the shaft is thereby adjusted to retain the shaft speed in a range for effective wind energy conversion. During starting the stages are idled until an operational speed is reached. Power assisted starting can be achieved by initially reversing the fluid flow through selected stages. Constricting means is located in the common discharge line from all stages and can be additionally located in each discharge line from each stage.
