Patent number: 7704467Abstract: A composition for the treatment of a liquid, particularly a body of water, such as a swimming pool, spa, or the like. The composition includes calcium hypochlorite, a water soluble zinc salt for controlling algae, and sodium aluminate as an agglomerating agent that may safely be combined with said calcium hypochlorite and said zinc salt. A floating chemical dispenser for containing and dispensing chemicals to treat a body of water. The dispenser includes an upper end float, a container adapted to contain chemicals, the container removably joined with the upper end float, and a free end float joined with the container.

Patent number: 5928608Abstract: Swimming pool or drinking water is chlorinated by the use of an intermittent spray-type chlorinator assembly. The chlorinator assembly includes a chamber for holding a quantity of solid dry chlorinating chemical, typically in the form of briquettes or pellets.The water spray impacts, abrades, and dissolves the briquettes to a degree, and at a rate which is controlled by the velocity of the spray; the diameter of the support grid; the percentage of open space in, and the thickness of the support grid; and the cyclic timing of the spray. The chemical-water mixture falls into a chamber below the spray and is evacuated therefrom through discharge/check valve assembly to a return line that leads back to the source of the water being chlorinated. The spray duration times and the intervals therebetween can be selectively changed by an attendant.Type: GrantFiled: January 8, 1998Date of Patent: July 27, 1999Assignee: Arch Chemicals Inc.Inventors: Kenneth John Levesque, Richard M. Mullins, Rocco Telese, David W. Blanchette

Patent number: 5133381Abstract: An improved chemical feeder employing periodic partial immersion in a forced circulation system is provided having a soluble chemical hopper, and a dissolving chamber into which the soluble chemical chamber extends an adjustable distance and a discharge chamber in fluid flow communication with the dissolving chamber to selectively receive chemically treated water from the dissolving chamber and discharge it into a flow loop connected to the forced circulation system. A visual indicator ring is preferably present to show the height of the hopper. The adjustable hopper allows an expanded range of chemical feed rates for the feeder.Type: GrantFiled: October 29, 1990Date of Patent: July 28, 1992Assignee: Olin CorporationInventors: Richard B.
