Patent number: 5580448Abstract: A device for delivering chemical solutions into a liquid flow, where said chemical solution is created by dissolving solid chemical contained within a chemical cartridge, the device comprising a base member and housing connected into a fluid flow line such that liquid flows into the base member, into the housing and back out through the base member, and further comprising a chemical dispenser having an upper conduit member, an apertured midsection and a chemical containing lower cartridge, the cartridge having an intake aperture located on the upper portion of its side wall and a dispensing aperture on its top, such that a saturated chemical solution is formed in said cartridge and passes into the liquid flow through the dispensing aperture due to the pressure differential of the liquid flowing into the apertured midsection and through the upper conduit out of the device.Type: GrantFiled: December 28, 1995Date of Patent: December 3, 1996Inventor: John B. Brandreth, III

Patent number: 5569331Abstract: A method and apparatus are provided for removing oil from absorbent materials of the type used in components for absorbing oil and containing oil spills. The components are first passed through a press to squeeze some of the oil from the components. The components are then shredded to separate the components into separate pieces of the absorbent materials. An auger pushes the pieces of absorbent materials into an elongated tubular trommel having a perforated sidewall. The pieces of absorbent materials are sprayed with treatment fluids as the trommel is rotated to tumble the absorbent materials within the trommel. The oil and treatment fluids drain from the absorbent materials, and pass through the perforations in the trommel sidewalls and onto a collection trough. The collection trough directs the oil and treatment fluids through a separator to reclaim treatment fluids and oil for later use.Type: GrantFiled: January 6, 1995Date of Patent: October 29, 1996Inventor: John Barber, III

Patent number: 5536479Abstract: A solubilizing apparatus includes a fluid permeable sleeve having opposed openings therein wherein a spray nozzle is in flow communication with one opening and a second opening is disposed to receive solids. The spray nozzle is designed to spray a fluid in a swirling spray sweeping the insides of the sleeve wall as it travels toward the opposite end. The solubilizing apparatus is specifically useful for dissolution of chemicals utilized in cleaning reverse osmosis membranes.Type: GrantFiled: October 17, 1994Date of Patent: July 16, 1996Assignee: International Purification Systems, Inc.Inventors: Steven L. Miller, Kerry L. Embry

Patent number: 5489415Abstract: The present invention relates to an improved urinal block composition comprised of fluid-soluble chemical components, and an improved dispenser to be used with that urinal block. Specifically, the present invention is directed to a unique combination of chemicals that when blended together to form a urinal block composition yields a stable product that is effective at deodorizing and cleaning urinals and toilets. The improvement of using an acid stable protease enzyme with the other fluid-soluble chemical components of the urinal block composition provides the advantage of dissolving and otherwise neutralizing odors associated with urinals and toilets. The urinal block is retained in and dispensable from a disposable dispenser assembly 10 for use in urinals and toilets.Type: GrantFiled: June 16, 1994Date of Patent: February 6, 1996Assignee: Eftichios Van VlahakisInventors: Eftichios Van Vlahakis, John A.

Patent number: 5484578Abstract: A distributor system for uniformly directing vapor and liquid across the surface of a fixed bed of solids in a downflow reactor comprising a distributor tray, and a plurality of open-ended downpipes extending through the tray. A first array of the downpipes has a plurality of vertically spaced elevations of holes above the level of the tray. A second array of the downpipes has at least one elevation of holes at substantially the same height above the level of the tray as one of the upper elevations of holes in the first array of the downpipes. But, the second array has no elevation of holes corresponding to the lowermost elevation of holes, and possibly other lower elevations of holes, in the first array of downpipes. The absence of the lowermost holes in the second array of downpipes causes the liquid flow rate through the distributor tray at a given liquid height to be reduced when that liquid height falls below the elevation of the holes second from the bottom in the first array.Type: GrantFiled: June 20, 1994Date of Patent: January 16, 1996Assignee: Mobil Oil CorporationInventors: Gregory P. Muldowney, Ronald A. Weiss, Julian A. Wolfenbarger

Patent number: 5389345Abstract: A water treatment pill is disclosed having a cylindrical periphery and disklike end faces and comprising material that in use is eroded to treat the water. The cylindrical periphery of the pill is covered with a cover of water impermeable material to prevent water coming into contact with the periphery of the pill. A passage is provided between the sleeve and the periphery of the pill and running from one end face to the other. This passage may be formed in the periphery of the pill or in the sleeve. One end face of the pill is closed off by a closure member. Thus with the axis of the periphery vertical and the closure member on the upper face of the pill, any gases which may accumulate below one end face of the pill can escape along the groove to the other end face.Type: GrantFiled: October 1, 1993Date of Patent: February 14, 1995Inventor: Michael B.
