    Abstract: A dispenser for dispensing solid or liquid water-conditioning/treating agents into a body of water (such as a pool, hot tub, or the like) comprises a hollow body adapted to receive water treating agent which can be solid (tablet form), granular, powder or liquid. The dispenser has an overall specific gravity such that, when the dispenser is substantially empty of water-conditioning/treating agent(s), the dispenser will float, but when the dispenser contains water-conditioning/treating agents, the dispenser will sink.

  • Patent number: 8728406
    Abstract: Dispensers, principally of water-treatment chemicals, are detailed. The floating dispensers may be inherently unstable in use, rotating approximately ninety degrees (from a generally vertical position to a generally horizontal one) over the useful lifespan of the chemicals initially contained within. Movement of the dispensers to horizontal positions signals users to replace the depleted chemicals. The dispensers also may be stacked into smaller volumes for transit and storage and need not include a separate component for flow adjustment. Rotation of its components additionally may create a “dial-a-dosage” feature of the dispenser, effectively varying depletion rate of the chemicals contained therein.

    Abstract: A system and method for extracting active elemental iodine from the contact of water with stored crystal iodine and for introducing the extracted elemental iodine into a water supply line and/or otherwise making the extracted elemental iodine available for an intended use. The system operates by allowing a portion of the water entering from a water supply line to be redirected to a first housing where it makes contact with stored crystal iodine causing to extract active elemental iodine. The iodinized water leaves the first housing and enters a second housing where it makes contact additional stored crystal iodine to help stabilize the elemental iodine concentration. The system can be designed to provide the elemental iodine in more than one potency concentration through the use of a metering valve and different travel routes for the elemental iodine out of the second housing.

    Abstract: A system for the continuous use and recapture of a catalyst in liquid, comprising: a generally vertical reactor having a reaction zone with generally downwardly flowing liquid, and a catalyst recovery chamber adjacent the reaction zone containing a catalyst consisting of buoyant particles. The liquid in the reaction zone flows downward at a rate which exceeds the speed of upward buoyant migration of catalyst particles in the liquid, whereby catalyst particles introduced into the liquid in the reaction zone are drawn downward with the liquid. A slow flow velocity flotation chamber disposed below the reaction zone is configured to recapture the catalyst particles and allow them to float back into the catalyst recovery chamber for recycling into the reaction zone, rather than being swept downstream. A novel 3-dimensionally adjustable solar reflector directs light into the reaction zone to induce desired photocatalytic reactions within the liquid in the reaction zone.

    Abstract: A container apparatus comprising a hollow container body having a first end and a second end. The first end constitutes the top of the device while the second end constitutes the bottom of the device. A lid is removable from the second end. This removable lid will enable access to the interior of the container. This access will allow for items, such as chemicals, to be placed therein. Secured to the first end is a three dimensional ornamental. Punchable indentations are located along the encompassing side wall of the container body for allowing the container to act as a chlorinater when submerged in water and having the appropriate amount of holes punched.

  • Patent number: 6358425
    Abstract: A pool apparatus that simultaneously removes debris from the water and purifies water in a portion of the water passing through the pool apparatus with the pool apparatus having an intake head for drawing water and debris from a first region of the pool and directing the water and debris to a housing having a restrictor therein for directing a portion of the water through a water purification material and the remaining portion with the debris therein along an unimpeded path in the housing to a collector where the debris is collected and the water is returned to the pool.

  • Patent number: 6340431
    Abstract: A self-contained and free floating spa chemistry monitor unit is provided for automated checking and adjustment of water chemistry in a spa or hot tub or the like to maintain the spa water in a clean and substantially sanitary state. The spa chemistry monitor unit includes a relatively compact buoyant housing having an on-board controller coupled to a plurality of sensor electrodes in contact with the water, wherein the controller is programmable to cause the sensor electrodes to take water chemistry readings such as hydrogen ion concentration (pH) and oxidation reduction potential (ORP) levels at predetermined time intervals. The monitor unit responds to the water chemistry readings to deliver a selected metered dose of one or more chemicals to maintain water chemistry readings within a selected target range for substantially optimized water clarity and hygiene.

  • Patent number: 6309538
    Abstract: A self-contained and free floating spa chemistry monitoring and dispensing unit is provided for automated checking and adjusting of water chemistry in a spa tub or the like to maintain the spa water in a clean and substantially sanitary state. The unit includes a compact bouyant housing having an on-board controller coupled to a plurality of sensor electrodes in contact with the water. The controller is programmable to cause the sensor electrodes to take water chemistry readings at predetermined time intervals in order to determine, for example, the pH or the oxidation reduction potential of the spa water. A dispensing means is operated by the controller to dispense chemicals to the water in an amount responsive to the water chemistry readings. The dispensing means includes metering assemblies mounted within the necks of bottles, wherein each bottle contains a respective chemical for affecting spa water chemistry.

  • Patent number: 6238553
    Abstract: A buoyant water conditioner has a housing with an upper surface and an apertured chamber for receiving a chlorination agent. Three separate measurement systems are carried by the housing: a water temperature system, a pH level system, and a chlorine concentration system. Each system has a sensor for measuring the respective water parameter, a display for displaying the measured value, and a processor for converting the sensor signals to display driving signals. Each system is powered by a solar cell battery or a chemical battery.

  • Patent number: 6123842
    Abstract: The present invention provides a dispenser for dispensing a water treatment substance into water. The dispenser contains a holder for holding a supply of a solid water dispersable water treatment substance. The holder has at least one primary water opening through which untreated water can enter the holder and treated water, containing water treatment substance dispersed therein, can exit the holder or be dispensed from the holder. A component is attached to the holder and has a secondary opening which is spaced from the primary opening and through which untreated and treated water can pass. An enclosed water flow path is defined between the primary opening and the secondary openings.

  • Patent number: 6065690
    Abstract: A tension-actuated submerged dispenser for discharging a liquid of one composition into liquid surroundings constituted by a liquid of a different constitution is useful for unattended employment to maintain a certain quality of composition in the surroundings. On the other hand, the quality of composition of liquid in the dispenser can be jeopardized if liquid from outside the container is allowed in, as has been the case with some earlier known submerged dispensers which employed a displacement liquid. In order to develop the necessary pressure to express a liquid through an orifice in a submerged container into which no such displacement liquid is allowed entry, a system of actuating a reduction of enclosed volume by means of tensing a container between opposed end-effectors has been developed. The source of pulling force can be either an externally attached weight or float, or a dispensed liquid which is differentiated as to specific gravity from that of the liquid surroundings.
