Patent number: 4071336Abstract: A gas and vapor separator includes an axial fan with blade members which carry an absorbing material. A power means, such as an electric motor, rotates the fan, which causes the adulterated fluid to pass through the apparatus.

Patent number: 4066552Abstract: A rotating centrifugal impeller spins contaminated fluid at high speed around the outside of a stationary cylindrical particle barrier filter screen and by centrifugal action separates the solid contaminants for removal to a dirt accumulator. Simultaneously, the impeller pumps or propels the remaining clean fluid radially inward, causing it to turn abruptly from its tangential path and to flow through the screen openings to a central chamber from which the fluid is discharged. Even though some of the solid particles may be smaller than the screen openings, they cannot turn radially inward from their trajectories sharply enough to pass through the openings and instead will be contained in their tangential path until centrifuged outward. The barrier screen has a smooth external surface so that it may be washed clean by the high velocity tangential flow of the spinning fluid across the screen, thus preventing any particle build-up on the screen and clogging thereof during start-up and shut-down.Type: GrantFiled: July 7, 1975Date of Patent: January 3, 1978Assignee: Sundstrand CorporationInventor: Gerard H. Caine

Patent number: 4059419Abstract: Particulate matter is separated from an aerosol by a process in which the aerosol is spun fast enough to create a vortex therein. The temperature in the relatively colder inner zone near the axis of spin of the vortex is made to fall low enough to cause at least part of the particulate matter to be wet therein by the condensation thereupon of vapor. This vapor is introduced or evaporated into a relatively warmer outer zone of the vortex farther away from the axis of spin.Type: GrantFiled: July 11, 1975Date of Patent: November 22, 1977Inventor: Leon Irving Ross

Patent number: 4047912Abstract: A turbocharger and intake air cleaning device for use with internal combustion engines. A collection spout is mounted tangent to the volute of the diffuser housing at a position from the turbocharger's discharge port which is upstream relative to the direction of rotation of air within the housing. A nozzle is mounted in the distal end of the collection spout. Dirt and other foreign matter carried in the rotating air stream migrates by centrifugal action into the collection spout where it is separated from compressed air flowing through the discharge port. An opening in the nozzle expels the foreign matter while at the same time limiting air leakage so as to maintain boost pressure within the diffuser.Type: GrantFiled: June 11, 1976Date of Patent: September 13, 1977Assignee: Consolidated Freightways, Inc.Inventor: R. Donald Markland

Patent number: 4046527Abstract: Apparatus comprising a vessel provided with electrodes, magnet and cooling means designed for the stable confinement of an ionized gaseous mixture or a plasma inside a heavy gas envelope that moves at high speed along the inside of an electrically gas-repelling vessel wall. The apparatus may be used not only for bringing about thermonuclear reactions, but also for separating gases of different specific mass from one another.Type: GrantFiled: February 8, 1974Date of Patent: September 6, 1977Assignee: Ultracentrifuge Nederland N.V.Inventor: Jacob Kistemaker

Patent number: 3983796Abstract: An exhaust fume treatment apparatus for removing suspended or entrained material from a gas including a substantially cylindrical housing having a peripheral wall and inlet and outlet openings in opposite end walls. A slinger wheel is rotatable within the housing and has circumferentially spaced, nonoverloading blades. A blower has its inlet connected to the outlet of the housing. Polluted fumes are drawn into the housing by the blower and pass outwardly through the slinger blades whereby the materials in the gas are deposited on, and thrown substantially radially outwardly by the blades, toward the peripheral wall of the housing for collection. A two stage gas deflector within the slinger wheel spreads the flow of gas more uniformly over the slinger wheel blades. A cylindrical screen encircles the slinger wheel and has plural openings angled toward the housing inlet end.Type: GrantFiled: January 30, 1975Date of Patent: October 5, 1976Inventor: Willard K. Ahlrich

Patent number: 3964885Abstract: A centrifugal pump has a rotor with two aligned frusto-conical passages, between the larger ends of which is a centrifugal impeller. The lower, smaller end of one of the passages forms a pump inlet. Frusto-conical funnels within the passages act to separate a vapor core from a liquid which is ejected by the impeller. The vapor is ejected from the smaller end of the other passage. A deflector and vanes within the rotor assist ejection of the vapor.Type: GrantFiled: June 18, 1974Date of Patent: June 22, 1976Assignee: Joseph Lucas (Industries) LimitedInventors: Harry Simister Bottoms, Leslie Holliday

Patent number: RE30836Abstract: A liquid-gas separator unit with superior performance characteristics is disclosed. The unit is characterized by a high liquid flow rate capacity at high as well as low accompanying gas flow rates, and efficient liquid-gas separation capability. The unit has a unique discharge plug element and a unique intake plug element that cooperate with a unique impeller means. Inlet/recirculation openings in the unit casing act to increase the liquid flow rate.Type: GrantFiled: April 25, 1980Date of Patent: December 29, 1981Assignee: Kobe, Inc.Inventor: Philip R. Bunnelle
