  • Patent number: 8016917
    Abstract: A method of improve the removal of particulate matter, heavy metals, neutralizing acid, and kill microorganism pollutants, known to be in contaminated air volumes of occupied confined spaces, when exposed in close contact under pressure to a mixture of alkaline sorbent materials, having a known synergism between said pollutants using a self propelled fluidized bed reactor and packed bed filter apparatus system to optimize the contact collection efficiency of submicron particles and organic compounds.
    Type: Grant

  • Patent number: 7569089
    Abstract: A boundary layer propulsion apparatus for propulsion of a fluid is provided. The boundary layer apparatus has a casing with an inlet and outlet. Supported in the casing is a tubular-shaped flow conduit which defines an interior space, the conduit positioned for rotation about its longitudinal axis. Extending from the conduit are multiple generally planar,generally parallel, spaced-apart disks which form multiple open annular spaces between the disks. Multiple ports provide fluid communication from the interior space of the flow conduit to the spaces between the disks. A motor or prime mover rotates the flow conduit which then imparts movement of the fluid from the interior space of the flow conduit, through the ports, along the adjacent spaces between the disks and then out of the casing through the outlet. A boundary layer turbine apparatus of similar design is also presented.

  • Patent number: 7241106
    Abstract: A two staged fluid propulsion apparatus of the type which utilizes prior art pitched blades combined with solid boundary layer disks supported by a novel rotating tubular flow conduit perforated to allow fluid flow to from the interior of the tube to the exterior surface positioned to outlet into spaces between a plurality of solid disks mounted within a volute case housing containing a singular fluid outlet and in communication with a plurality of fluid inlet ports.

  • Patent number: 6451091
    Abstract: A method of improving the removal of particulate matter, heavy metals, and acidic gases in waste gas emission streams through continuous filter control through the utilization of independent chambers to divert the flow of waste gas during the cleaning and precoating cycles of the chamber to optimize emission collection efficiency and prevent fugitive emissions.
