Abstract: A system 10 for extracting free oil from industrial processing fluids contains a solids retention cartridge 20 having a plurality of vertically oriented polymeric elements 28 therein. The cartridge 20 fluidly communicates with a retention chamber 36, wherein the retention chamber 36 provides a predetermined residence time based on fluid flow as established by inlet and outlet pressure and also as established by valved fluid exit orifices. An aggregation chamber 48 fluidly communicates with the retention chamber 36 and provides an area for aggregation of a low density fluid such as oil, for example. The low density fluid is then decanted from the aggregation chamber 48. The purified bulk fluid is drained from the retention chamber 36 through an associated return chamber 40. The average cross-sectional area of the aggregation chamber 48 is less than the average cross-sectional area of the retention chamber 36 thereby enhancing the aggregation of a lower density fluid such as oil, prior to decant.

Abstract: A cartridge filter shaped as a dome with inlet and outlet. A plurality of horizontal filter cells are stacked and locked together during assembly and operate to remove submicron sized particulates, by passing the fluid through horizontal filtration cells composed of granular filter aids containing large filter areas.

Abstract: A sleep assist article and associated method for establishing proper breathing patterns. An adhesive tape body is releasably secured upon a face of a person and exhibits an inner aperture defined by an inner edge surface, and through which upper and lower lips of the person extend. The body establishes a check valve in a first inhalation stage, to facilitate breathing through the person's nasal passages while inhibiting inhaling orally. The body further operates to permit exhaling orally, and while concurrently inhibiting nasal exhalation. The device optimizes an oxygen intake percentage within a user's lungs, as well as an associated oxygen saturation during repetitive breathing cycles associated with an induced sleep pattern and to improve sleep cycles, reduce incidences of sleep apnea, and to provide other health benefits.

Abstract: A deep bed filter principally used for filtration of contaminated aqueous fluid comprises a top layer of polymeric cylindrical particles in combination with at least one layer of sand. The polymeric cylindrical particles are approximately 1.5 millimeters in diameter and in one embodiment range 6-12 millimeters in length, with a specific gravity of approximately 1.15. When the filter is backwashed, sand particles mix with a portion of the polymeric particle layer, thereby creating larger surface voids for penetration of larger contaminant particles into the filter.

Abstract: A vacuum filter includes a cylindrical filter drum 12 having both a perforate section 14 and an imperforate section 16. The drum is positioned in a tank 20 so that the imperforate section is oriented upwardly therein. A level controller is provided to maintain the level of contaminated fluid below the top of the imperforate section but above the perforate section. A filter belt 54 wrapped around the filter drum is repositioned by rotating the drum when the differential pressure between the interior and exterior of the drum reaches a predetermined value. The inlet ends 35 of the suction pipes 34 are continuously positioned at the lowest point of the drum so that the pump does not lose suction when the drum is rotated thereby facilitating continuous filtration of the contaminated fluid through the vacuum filter.

Abstract: A deep bed filter principally used for filtration of contaminated aqueous fluid comprises a layer of polymeric cylindrical particles in combination with a layer of anthracite particles and a layer of sand. The polymeric cylindrical particles are approximately 1.5 millimeters in diameter and in the range of 6-12 millimeters high, with a specific gravity of approximately 1.15. When the filter is backwashed particles of anthracite mix with a portion of the polymeric particle layer, thereby creating larger surface voids for penetration of larger contaminant particles into the filter.

Free oil is removed from the coolant through oleophilic attraction between the free oil and the surface of the polymeric elements. Free oil remaining in the coolant is further separated from therefrom through Gravitational separation. A plurality of weirs and baffles interposed between the settling chambers provide continuous return of purified coolant to the system and periodic decanting of separated free oil.

A cylindrical filter media is disposed between the disc support rods. Unfiltered liquid is admitted to the interior of the drum filter and flows radially outwardly therefrom through the filter media. Reciprocating backwash nozzles direct high pressure liquid radially inwardly against the exterior surface of the filter media to backwash contaminants collected on the radially inner surface thereof into a contaminant collector disposed internally of the filter drum. The filter media is sealably connected to the circular disks by a novel retention system.

Abstract: A coalescer system (10) for oil-in-water soluble oil emulsions utilized as coolants and cutting oils for machining processes in industrial plants, comprises a deep bed of granular hydrophilic media particles (24) to effect coalescence of insoluble soaps and reverse phase water-in-oil droplets. The coalesced insoluble soaps and reverse phase emulsions flow to the liquid surface in tank (12) along with other contaminants that have an affinity for the reverse phase oil droplets and insoluble soaps, all in the form of floating waste (26). The waste (26) is then discarded. Effluent coolant may be transported back into the cooling system. The system (10) increases the stable life of the oil-in-water emulsion, minimizes the formation of foam, and removes other abrasive or otherwise harmful nonhomogeneous contaminants from the soluble oil emulsion.
