Patent number: 7238278Abstract: The invention relates to a method for purifying water by forming in an electrolytic cell molecular halogen, hypohalic acid, hypohalite ions or combinations thereof, from halide ions dissolved in the water; and dissolving one or more soluble metal salts in the water to provide corresponding metal ions. The invention also relates to a system for purifying water, having an electrolytic cell comprising a plurality of electrodes sufficient to electrolytically convert halide ion in the water into molecular halogen, hypohalic acid, or hypohalite ions, or combinations thereof; and a metal generator, which provides concentrations of one or more metals to the water.Type: GrantFiled: October 28, 2002Date of Patent: July 3, 2007Assignee: Zodiac Pool Care, Inc.Inventors: Richard T. Coffey, Alvin Costa, Raymond Albert Hin, Gary Andrew Kennedy, Christopher Kampf, Daniel Nelsen, Michael Pereira

Patent number: 7141224Abstract: Vessels, or housings, and covers therefor are detailed herein. Loads and load-bearing surfaces exist principally at the periphery of the covers, by contrast with centralized loading utilized in other designs. In some versions of the vessels, a cover is sandwiched, at its periphery, between a cap assembly formed of both a jack ring and an upper component or cap and thus carried on and off the associated vessel when the cap is placed onto or removed from the vessel, respectively.Type: GrantFiled: June 7, 2001Date of Patent: November 28, 2006Assignee: Zodiac Pool Care, Inc.Inventors: Alvin Costa, Richard A. Coffey

Fluid flow diverters and diversion methods and water purification equipment including such diverters
Patent number: 6680026Abstract: “Plug-in” fluid flow diverters are disclosed. Additionally disclosed is water purification equipment adapted to communicate with the diverters. Such equipment is especially (although not solely) useful in connection with circulating streams of water present in systems associated with swimming pools, hot tubs, and spas, as the circulating nature of the water permits more of its volume ultimately to be diverted into the equipment for purification. The diverters, furthermore, may have entrances oriented to receive fluid travelling in only one direction through a conduit and be keyed to one or more components of the equipment for purposes of identification, inventory control, or otherwise.Type: GrantFiled: May 5, 1999Date of Patent: January 20, 2004Assignee: Zodiac Pool Care, Inc.Inventors: Raymond P. Denkewicz, Jr., Alvin Costa, Daniel J. Nelsen, Michael C. Pereira, Justin W. Sirotin, Michael Vieira, Aidan J. Petrie -
