Abstract: A system, a cartridge and a dispensing valve for eliminating a drift or sag in BCDMH output from an inline dispensing valve containing a dispensing cartridge mountable within the inline dispensing valve with the dispensing cartridge containing a batch of water erodible cluster inhibiting BCDMH particles to provide a linear output flow of BCDMH which is responsive to flow of water though a cartridge in the dispensing valve and a method of obtaining a linear output in a dispensing system by increasing the size of particles in a dispensing cartridge in the system.

Abstract: A floating dispenser for floatingly delivering a dispersant or dispersants to a body of water with the floating dispenser floating in an upright condition when a dispersant is present in a dispenser cartridge of the floating dispenser with the dispenser self inverting 180 degrees in response to consumption of the dispersant in the dispenser cartridge to thereby provide a visual alert that one should replace the dispenser cartridge in the dispenser with a fresh dispenser cartridge.

Abstract: A floating dispenser having an external float or an internal float for supporting a cartridge or cartridges for floatingly delivering a dispersant or dispersants to a body of water with the floating dispenser having cartridges rotationally positionable with respect to one another to control the rate of dispensing while the dispenser floats in an upright condition with the floating dispenser changing its flotation orientation in response to consumption of the dispersant or dispersants in the a cartridge to thereby provide a visual alert to replace a spent cartridge with a fresh cartridge. In addition the inventions described herein permit changing the dispensing nature of the system from a multiple dispensing system to a single dispensing system without changing the floating characteristics of the floating dispensers through replacement of a dispersant in one of the cartridges with an inert or ballast material that has no effect on the water characteristics.

Abstract: A filter well mountable dispenser holder securable within a hot tub filter well with the dispenser holder supporting replaceable dispersant containing dispensing cartridges positionable within a circulating flow of water through the filter well to thereby release dispersants therefrom without preventing the circulating flow of water from passing through the filter media proximate the dispensing cartridges.

Abstract: A multi-stage floatation dispenser for carrying a ballast, which may be a non-water consumable dispersant and at least one water consumable dispersant wherein the weight of the water consumable dispersant decreases as the water consumable dispersant is consumed with the weight of water consumable dispersant and the non-water consumable coordinated with the flotation capacity of a flotation dispenser to provide for either a two stage or a three stage dispensing mode.

Abstract: A system for limiting the flow from a dispensing valve when a dispensing cartridge is replaced with the system including a dispenser cartridge with a cam and a water socket with a flow limiter therein that is activeable in response to the position of the dispenser cartridge in the dispensing valve and operable in response to an upstream fluid pressure in the dispensing valve.

Abstract: A non-dissolvable immersible dispensing puck in the shape of a dissolvable halogen puck when the dissolvable halogen puck is in an undissolved state with the non-dissolvable immersible dispensing puck physically interchangeable with a dissolvable halogen puck when placed in a dispenser for normally holding only a set of halogen pucks to enable a single dispersant dispenser to be converted to a dual dispersant dispenser without changing the structure of the single dispersant dispenser by placing a dispenser within a dispenser wherein only one of the dispensers may be provided with adjustable water ports.

Abstract: A fitting connectable to an end portion of a pipe generally includes a tubular insert member configured to be received at least partly within the end portion of the pipe, and a retention member coupled to the insert member and configured to be received at least partly within the end portion of the pipe. The retention member operates in conjunction with the insert member to engage the end portion of the pipe and impart an increased force against an inner wall of the pipe in response to forces tending to separate the fitting from the end portion of the pipe. The insert member includes a plurality of reinforcement ribs formed on its inner surface which provide support to the insert member and help prevent damage thereto from transverse bending forces applied during installation.

Abstract: An inline dispersal valve that can be used with or without a base. One embodiment includes a rotatable member that is rotatable from a fluid stream obstructing condition to an out-of-the-way condition to prevent fluid diversion into the dispersal valve. Another embodiment includes a lever handle for quickly setting the amount of fluid being diverted into the inline dispersal valve. Another embodiment includes an indicator that can be viewed from a position above the inline dispersal valve. Another embodiment includes a cap that can be secured or removed without the aid of tools. Another embodiment includes a clip that allows one to disassemble the inline dispersal valve for servicing. Another embodiment includes a dispensing valve that can be reversed and still properly divert fluid into a dispersant chamber. Another embodiment includes an inline dispersal valve with a bleed valve positioned to allow one to bring the air volume in the dispersant chamber to the proper level.

Abstract: A filterwell cartridge holder having a face for compressible engaging pleats on a water filter cartridge and a further face holding a dispensing cartridge thereon in a position to release dispersants into a filterwell containing a water filter cartridge.

Abstract: A filterwell cartridge having ports for dispensing a dispersant directly into a filterwell of a hot tub, spa or the like with the filterwell cartridge peripherally and postionally supportable in a quick release mode through facial engagement of compound surfaces located on opposite sides of the filterwell cartridge.

Abstract: An indexable cartridge and method that is useable in either a stagnant fluid environment or in a moving fluid environment with the indexable cartridge floatable in a stagnant fluid environment and securable in a moving fluid environment with the indexable cartridge having a housing having one or more diffusion ports and a sleeve having one or more diffusion ports indexable to a diffusion port alignment through resilient yielding of the sleeve while a set of ribs inhibit lateral flow therebetween.
