  • Patent number: 8226375
    Abstract: Wind powers a rotor causing a shaft to rotate, thereby transmitting power to one or more pumps to pump colder sub-surface water from the depths, one or more flywheels to provide gyroscopic stability to the entire platform; and to a propeller to help the wind powered sea pump remain in a stationary position. A hull provides a sump for a single hose connector to feed water to the pumps from a pickup hose of desired diameter to a desired depth. The force of the wind powers the sea pump to transport colder water from a lower depth to the sea surface. A sea anchor provides a pivot point to keep the wind powered sea pump oriented directly into the wind and a weather vane helps with the wind orientation as well as providing space for use as an advertising bill board.

  • Patent number: 6439853
    Abstract: This circulation device is equipped with a water impeller that is larger than and tightly fitted over the top of the draft tube through which the water from the pond or reservoir is drawn. By placing the impeller above and out of the draft tube it enables to lift water through the draft tube and imparts a centrifugal force on the water above the impeller which aids in moving the water radially outward from the impeller. The water is directed outwardly over a large diffuser plate that is centrally located. The outer edge of the diffuser plate is equipped with a laminar flow diffuser lip which is designed to inhibit the passage of water from the diffuser plate to the open water. This design ensures that most of the energy imparted to the water by the impeller is retained once it leaves the diffuser plate, making the invention operate efficiently.

  • Patent number: 6039546
    Abstract: A float operated pneumatic pump which separates water from hydrocarbons within a well at the pump in accordance with the density or specific gravity of the water and hydrocarbon fluid. The pump includes a displaceable fluid inlet for allowing fluid to enter the pump which generally tracks the level of the water/hydrocarbon interface. The pump includes an outer tube forming an outer chamber and an inner or dip tube placed within the outer chamber of the outer tube and forming an inner chamber. A well float includes the fluid inlet and has a density which enable the float to remain in proximity to the water/hydrocarbon interface. A tubular coil or conduit provides fluid passage between the fluid inlet and the outer chamber. Also, a fluid separator is located at the bottom end of the outer tube and defines a fluid passage between the inner and outer chambers. In one configuration, the separator allows water to exit the pump from the outer chamber while the hydrocarbons remain within the outer chamber.

  • Patent number: 5662459
    Abstract: A pump mechanism adapted to float on a reservoir of liquid characterized by a floating enclosure provided with an internal chamber, an open cycling container, disposed within the chamber, an output pipe coupled to the cycling container and coupled to a swivel joint, which is connected to the lower wall of the enclose. A pressurized gas and/or steam source inlet tube, allows pressurized gas to enter the chamber. The interplay between the force of gravity and the force of buoyancy activated by the force of an expanding gas and/or steam are the factors which cycle this device in a pumping action. In operation the cycle begins with the chamber full of liquid and the cycling container resting on the bottom of the chamber. The pressurized gas forces liquid out of the chamber through the pipe located within the cycling container. This continues until the pressure has emptied the cycling container. The pressurized gas will now vent through this pipe.

  • Patent number: 5207897
    Abstract: An automatic pumping system for removal of floating contaminants and oil and gasoline seepage from water wells. A vertically reciprocating cone-shaped member, like an inverted funnel, is moved between positions above and below the water surface. As it submerges, the inverted funnel collects the floating product within its circumference and transfers it to a collection space surrounding the cone. In the upper position, this collection space is sealed so that air may be blown into it while the collected product is driven out through a pickup tube to a collection sump for ultimate disposal. A second embodiment incorporates a hydraulic pumping system which operates in synchronism with the contamination collection and disposal system to create a cone of depression which draws the floating product into the space covered by the circumference of the reciprocating cone.
