US Patent:

6680026, Jan 20, 2004
Filed:

May 5, 1999
Appl. No.:

09/305735
Inventors:

Alvin Costa - Tiverton RI
Daniel J. Nelsen - Providence RI
Michael C. Pereira - Lincoln RI
Justin W. Sirotin - Providence RI
Michael Vieira - Fall River MA
Aidan J. Petrie - Providence RI
Assignee:

Zodiac Pool Care, Inc. - Pompano Beach FL
International Classification:

C02F 150
US Classification:

422 28, 422266, 422282, 422283, 137268, 13759915
Abstract:

âPlug-inâ 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.

US Patent:

6982040, Jan 3, 2006
Filed:

Apr 16, 2003
Appl. No.:

10/414598
Inventors:

Alvin Costa - Tiverton RI, US
Richard T. Coffey - Pompano Beach FL, US
Michael Pereira - Smithfield RI, US
Daniel Nelsen - Providence RI, US
Thomas Parent - Providence RI, US
Christopher Kampf - Cranston RI, US
Assignee:

Zodiac Pool Care, Inc. - Pompano Beach FL
International Classification:

C02F 1/50
US Classification:

210753, 210764, 210169, 210199, 422 37
Abstract:

The invention relates to a method for purifying water by dissolving one or more soluble metal salts in the water to provide corresponding metal ions, by dissolving hypohalite into the water, and by regulating the residence time, and thus hypohalite concentration in the device using a venturi nozzle disposed between the metal generator and the hypohalite generator.

Appl. No.:

Alvin Costa - Tiverton RI, US

Assignee:

Zodiac Pool Care, Inc. - Pompano Beach FL
International Classification:

B01D 11/02
B01D 15/00
A61L 2/00
B65D 85/50
B65D 45/00
US Classification:

422261, 422 1, 422905, 422256, 422265, 422292, 422300, 422311, 2101981, 210232, 206423, 220315, 220319, 220325, 220327, 220255, 215273, 215274, 215276, 215283
Abstract:

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.
