Patent number: 6162407Abstract: A chemical dispenser for dispensing chemicals into a tank holding liquid, such as a swimming pool. The chemical dispenser has a housing, a lid, an inlet and an outlet. The lid is selectively attachable to the housing to permit a sanitizing chemical to be placed in the housing.In a method according to the present invention, a chemical dispenser having a housing, a lid selectively attachable to the housing, an inlet orifice and outlet orifice is provided, and the inlet orifice is positioned to receive circulated liquid from the circulating system outlet. Next, chemical to be dispensed into the circulated liquid is provided and placed in the housing. Then the lid is attached to the housing, and the outlet orifice is positioned such that the flow of liquid from the outlet orifice establishes a flow pattern in the tank which causes debris to travel to and be collected at a debris collection site of the tank.Type: GrantFiled: May 20, 1999Date of Patent: December 19, 2000Inventor: Mart A. Pihl

Patent number: 6117316Abstract: An apparatus for treating a stream of tap water flowing from the outlet of a fire hydrant comprises a T-shaped diffuser is combination with a frame having a pair of screens extending transverse with respect to outlets of the diffuser. A mesh bag containing a material in tablet form in mounted on each screen. In a preferred aspect of the disclosure, the material is sodium sulfite for interacting with chlorine in the tap water and converting the chlorine to a salt harmless to aquatic life.Type: GrantFiled: September 22, 1999Date of Patent: September 12, 2000Assignee: Washington Suburban SanitaryInventor: Russell Burton

Patent number: 5993753Abstract: A dual chemical feeder device treats a fluid simultaneously with two different chemical compositions which may not be wholly compatible. In an exemplary embodiment for application in swimming pools, hot tubs, spas and the like, a chlorinator is combined with a sanitizing canister in a chlorinator/sanitizer to chemically treat the full flow of water through the apparatus with a chlorine-based chemical composition and another chemical composition. In alternate embodiments, the chlorinator/sanitizer is configured as a parallel treatment unit and as a series treatment unit. In the series treatment unit, the full flow through the chlorinator also flows through the sanitizing media in the santizing canister, so that all the water is both chlorinated and sanitized by the chlorinator/sanitizer. In the parallel treatment unit, the flow within the unit is divided into two streams which are separately treated.Type: GrantFiled: February 11, 1998Date of Patent: November 30, 1999Assignee: H-Tech, Inc.Inventor: Donald R. Davidson

Patent number: 5976364Abstract: An apparatus provides for dissolving biotic growth inhibitor composition, usually in the form of blocks or tablets, into air conditioner condensate fluid to prevent biotic growth. Condensate fluid from a collector pan or receptacle near the air conditioner enters the apparatus and contacts the inhibitor composition, typically an algicide, and slowly dissolves the inhibitor. The apparatus has an inhibitor housing for holding the biotic growth inhibitor and an inhibitor container, located within the housing, which allows contact between the inhibitor and condensate while retaining undissolved inhibitor in the housing and preventing it from being washed out. The apparatus is connected with the drain pipe by an inlet port and an outlet port which direct the condensate into and out of the inhibitor housing.Type: GrantFiled: April 28, 1997Date of Patent: November 2, 1999Assignee: Innovation Unlimited, Inc.Inventor: Danny R. Williams

Patent number: 5759501Abstract: A container for institutional detergents, preferably tablets, includes a rigid large screened base and a flexible plastic film sidewall heat bonded to the peripheral surface of the base. The container is filled, preferably from its top portion, with tableted detergent and closed with a single heat seal along the top surface of the wall of the container. The screen surface is then closed with a removable, peel-off seal or removable cap. The upper portion of the container will include a handle which makes it easy to transport the container and place it into a dispenser for use. In use, a water nozzle will spray upwards onto the surface of the screen base through the holes in the screen, dissolving detergent and allowing the solution to pass downwardly to a drain, which directs it to a ware washing apparatus.Type: GrantFiled: November 15, 1996Date of Patent: June 2, 1998Assignee: Diversey Lever, Inc.Inventors: James Livingston, Donald Wright, Tiziano J.
