  • Patent number: 5228891
    Abstract: A gas filter assembly for removing particulates from the exhaust gas of a diesel engine comprising a housing having an inlet pipe for coupling to the engine and an outlet pipe open to the atmosphere is disclosed. The inlet pipe and the outlet pipe define an exhaust gas flow path. A self-contained filtering means is disposed within the gas flow path. The filtering means includes a plurality of inlet cells, microporous filter elements, filter support elements, and the outlet cells. The components of the filtering means are disposed such that the exhaust gas flows through the inlet cells, then through the microporous filter elements and filter support elements, and finally through the outlet cells. Each of the components of the self-contained filtering means are highly resistant to excessive temperatures, so that the filtering means may be regenerated by heat, which burns off accumulated, typically hydrocarbon, particulates.

  • Patent number: 5225083
    Abstract: A method for bioremediation of grease traps, which includes the steps of mechanically removing solid materials such as plastic items, food particles and the like from entrances to all drain lines and the drain lines themselves terminating in the grease traps; securing loose drain line covers and replacing broken covers; preventing the flow of all chemicals which are detrimental to the growth of endemic bacterial microorganisms into the drain lines and grease traps; adjusting the pH of the water effluent in the grease traps by introducing a basic material such as baking soda into the grease traps and mixing or stirring the water, which stimulates the endemic native bacteria resident in the grease trap; and adding endemic bacterial microorganisms to one or more of the drain lines for ultimate introduction into the grease traps and biodigesting grease in the drain lines and grease traps.

  • Patent number: 5224975
    Abstract: A deodorizing device for use in a pet's litter box, for example. The deodorizing device has a container body having an open end, a closed end and a cylindrical side wall defining a cavity therein. Chunks of zeolite are disposed within the cavity and retained within the container body by a sealing mechanism. The cylindrical side wall of the container body has a plurality of substantially uniform-sized apertures disposed thereon to permit exposure of the retained zeolite to the odors. A sealing mechanism may be permanently or releasably attached to the container body. A securing mechanism secures the deodorizing device to a structure within the malodorous environment. The zeolite after use can be recharged by exposing to fresh air, sunlight and heat and then reused. In addition to being used in a pet's litter box, the device can be used in many environments, including animal containment areas, living areas, production areas, food storage areas, work areas and automobiles.

  • Patent number: 5223006
    Abstract: An air cleaner box for a computer or other electronic equipment is disclosed in which the computer or other electronic equipment is inserted into an enclosure which is sealed from the outside environment in such a manner that all of the air entering the enclosure must do so through an electronic or other type of air cleaner which serves to remove the dirt, dust, smoke and other air borne contaminants from the environment before they reach the electronic equipment contained in the enclosure. The enclosure contains within it all of the equipment for operating the air cleaner filter as well as a cable access box which allows computer cables to be routed from the outside environment into the contaminant-free enclosure while providing a tight seal against air infiltration from the outside environment.

  • Patent number: 5221305
    Abstract: A device for separating multiple-component fluids includes a truncated cone structure having a conical main section defined by a plurality of coaxially aligned and axially spaced rings of progressively diminishing inner diameters as viewed in the direction of movement of the fluids being separated. The largest ring is located at that end of the conical main section at which the fluid is admitted thereto, and the smallest ring is located at that end of the conical main section at which separated solid particles are discharged. Each ring has an inside surface which is convexly curved in a radial cross-section along the axis of the cone structure and faces in part counter to and in part across the direction of fluid flow. The inside surface of each ring meets the bottom surface of that ring in a sharp edge, with the tangent to the bottom surface at that juncture making an angle of at most

  • Patent number: 5213596
    Abstract: An air cleaner device includes a filter element for filtering air and being disposed in a housing. The device comprises a hollow housing having an inlet portion, an outlet portion, and a flow passage therein which is communicated with the inlet portion and the outlet portion. The housing also has an opening which is disposed between the inlet portion and the outlet portion, and communicates the flow passage with the exterior of the housing. A filter element is inserted through the opening into the flow passage, disposed between the inlet portion and the outlet portion, so as to filter the air flowing through the flow passage. A lid is mounted on the housing for covering the opening. A resilient urging member allows the lid to be urged toward the housing so as to close the opening, and the resilient urging member allows the lid to be moved away from the opening when this urging is released.
