Abstract: The present invention relates to a web based system for handling commodity transactions. The system is an electronic system, and allows for the central filing, storage, issuance, maintenance, cancellation and other actions associated with electronic warehouse receipts, electronic price later credit sales contracts and electronic reports, including status and position reports.

Abstract: An apparatus and method for controlling a water characteristic of a body of water by controlling the cyclic release of a water characteristic material into the body of water with or without the system being responsive to a level of the water characteristic in the body of water with the system capable of being controlled from a display or from a wireless control module or both.

Abstract: A two part biocide composition containing metal ions and bromine donor for killing microorganisms in a body of water and a method of killing microorganisms in a body of water by placing both metal ions and a bromine in the body of water to allow use of lower concentrations of bromine than if bromine were used alone as a biocide.

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 universal cartridge that is useable in either a stagnant fluid environment or in a moving fluid environment with the universal cartridge floatable in a stagnant fluid environment and securable in a moving fluid environment with the universal cartridge having an inner housing having a diffusion port and an outer sleeve having a diffusion port with the housing and the sleeve mateable engaged with each other through frictional engagement to inhibit flow therebetween while permitting rotational displacement of the housing with respect to the sleeve to allow one to increase or decrease a dispersant transport area between a zone within the housing to a zone exterior to the housing through aligning a recessed diffusion port of the housing with a diffusion port of the sleeve with the diffusion ports inhibiting fluid flow therethrough but permitting dispersant transfer therethrough.

Abstract: An inline dispenser and purification device combination comprising an inline dispenser having fluid ports directly mateable to the ports of a fitted cartridge and a universal cartridge having no ports for connection with the fluid ports of the inline dispenser and a method of replacing a fitted cartridge located within a inline dispenser with a universal cartridge having no ports for connection with the fluid ports of the inline dispenser.

Abstract: A dual filter apparatus and a process of making a dual filter apparatus that minimizes disruption to the normal flow pattern through the filter apparatus by forming a porous medium suitable to carry a fluid activator and placing an activator proximate the porous filter medium for in situ fluid treatment and removal of debris from the fluid by screening action of the porous filter medium that entraps debris thereon.

Abstract: A liquid treatment method and system with the liquid treatment system having a container for holding a liquid treatment material therein with the liquid treatment device effectively positionable in various transitional regions in the liquid system to provide for an enhanced dispersant rate in response to increased activity in the body of water.

Abstract: A dendrimer complex comprising a dendrimer and an antimicrobial agent with the dendrimer complex placeable directly into a fluid to inhibit growth of microbes or rid the fluid of microbes. In a further embodiment of the invention the dendrimer complex is secured to a carrier, which is placed in a body of fluid and allowed to dispense the antimicrobial agent into the fluid. Once the antimicrobial agent is dispensed, the dendrimer complex can be removed and recycled to add functional groups to the dendrimer so that the dendrimer can be reused.

Abstract: A water treatment device, method and system with the water treatment device having a container for holding a water treatment material therein with the water treatment device including a shroud extending in a direction generally normal to a flow of debris laden water with the shroud inhibiting direct flow of debris into a water inlet in the water treatment device by directing water and debris over the shroud and around the water treatment device while a portion of the water can be directed laterally into the water treatment material within the water treatment device to thereby purify the water that flows over the water treatment materials with the water treatment device including multiple spaced and positioned water inlets so that the likelihood of the water inlet being completely obstructed is remote.

Abstract: Improved water treatment minerals and a canister with a divider platform for use in a dispersal valve to enable a fluid mixing stream to be bifurcated and simultaneously but separately treat the water flowing therethrough with water treatment compositions containing bacteria killing chemicals and bacteria killing minerals.
