  • Patent number: 4595497
    Abstract: A reverse osmosis system in which a pair of oppositely disposed, vertically aligned rigid cup shaped bodies that have outwardly extending first flanges are by a circumferentially adjustable band forced into pressure sealing contact with a second flange of a pliable cup shaped barrier to define a reservoir. The barrier when not deformed occupies only a portion of the interior of one of the cup shaped bodies, and requires a minimum of material to define. The uppermost one of the cup shaped bodies supports a single valve that has a pressurized feed water inlet and outlet, and a movable portion that extends into the interior of the upper cup shaped member. Upward movement of the movable portion throttles the rate of flow of pressurized feed water between the inlet and outlet.

  • Patent number: 4532769
    Abstract: An energy storing flywheel assembly in which first and second reels are operatively connected by a flexible band, with the first and second reels capable of being rotated by first and second electric motors, and the second reel that can rotate either clockwise or counter clockwise through a clutch mechanism driving a flywheel. The flywheel that stores rotational energy is free to rotate independently of the second reel in a clockwise direction except when it is eccelerated to a predetermined maximum rate by the second reel. Acceleration of the flywheel occurs as the first motor drives the first reel at a constant rate to wind the band thereon. After the flywheel has reached the desired maximum rate of rotation the second reel is rotated to rewind the band thereon. Upon the rate of rotation of the flywheel decreasing to a predetermined minimum the above described operation is repeated.

  • Patent number: 4528129
    Abstract: Radioactive and associated chemical contaminants present in uranium mill tailings, for example, are isolated from the environment. A matrix product is formed by combining selected clays and lime with the soluble radioactive and chemical contaminants. The clays absorb the majority of all the contaminants. The lime neutralizes the contaminants and cements the clay silicates and absorbed contaminants. The resulting product is of a matrix-like nature and is reverted into a limestone by the uptake of carbon dioxide in a recarbonization process. The radionuclides and chemical contaminants in the resulting product are converted into insoluble oxides or hydroxides which do not appreciably leach out into the ground water. The release of radon gasses is substantially inhibited in the final product, and the release of radon gasses is virtually nonexistent in the final limestone.

  • Patent number: 4523536
    Abstract: A water jet propelled boat that includes a source of pressurized air that by a single action control may be delivered to bow and stern portion positioned resilient bags to inflate the same to vary the contour of the wetted portion of the boat to a desired configuration. The boat includes a number of laterally spaced sponsons that have forward bottom surfaces that taper downwardly to merge into substantially straight rearward bottom surfaces on which the boat rides when traveling at high speed. Pressurized air is discharged from the source to flow rearwardly under the boat and impart a lift to the latter. The desired configuration of the bags is one which in combination with the action of the sponsons and the rearwardly flowing bubbles results in the boat moving through the water in a fuel efficient manner.

  • Patent number: 4503703
    Abstract: An apparatus in which a current of air is directed across a surface of a substance of unknown identity to have molecules of the latter entrained therewith. The molecules are attracted electrostatically to the surface of a piezoelectric element to cause microscopic vibrations of the element. The microscopic vibrations result in the piezoelectric element emitting a minute voltage at a like frequency that is subsequently amplified. The amplified voltage is used to produce pulsed sound waves that are directed onto a resilient diaphram to vibrate the latter, and the mechanical energy of the diaphram being transferred to the piezoelectric element to amplify the voltage emitted. The amplified voltage is of sufficient magnitude to actuate an oscilloscope or recording computer to provide a distinctive pattern that is used to identify the unknown substance.

  • Patent number: 4499858
    Abstract: An improved fuel burning assembly particularly adapted for use with a boiler having a fire box situated below an array of boiler tubes. The assembly discharges a number of spaced rotating streams of minute droplets of a flowable fuel both laterally and longitudinally into the fire box to intermix with a stream of air that is moving rearwardly therein. The fuel air mixture when burning blankets substantially all the boiler tubes with a sheet of flame. Due to such flame contacts substantially all of the boiler tubes are heated uniformly thereby, rather than only a portion of the boiler tubes being contacted by the flame as occurs in a boiler when a conventional burner assembly is used. As a result of the flame distribution and uniform heating of the boiler tubes, an increased thermal efficiency is attained in the operation of the boiler on which the burner assembly of the present invention is used.
