Abstract: The combination of a passive dosing dispenser, of the type having a reservoir containing a cake of active ingredients which are depleted as water is routed through the dispenser, and an improved hypochlorite cake for use therein. The improved hypochlorite cake provides water-soluble hypochlorites, and additionally contains materials capable of forming a water-insoluble matrix from which hypochlorite salts may be leached out by the water in the reservoir. The size of the cake desirably increases somewhat while the dispenser is in use so that the mass of aqueous hypochlorite which may be poured from the reservoir of the dispenser remains constant or slightly decreases as the active ingredients are used up.

Abstract: A toilet bowl cleaning means wherein a container is located within a water tank associated with the bowl with a cleaning compound such as calcium hypochlorite included within the container. A plurality of openings are provided, and this provides exposure to water in the tank so that the compound will be dissolved in the water and thereby delivered to the bowl when the toilet is flushed. The openings may be formed in a centrally located cylinder with the compound located within the cylinder and with a water space between the cylinder and the outer container walls. Controlled amounts of compound are thereby released to the water in this area.

Abstract: A float dispenser is adapted to be floated in a body of water such as a swimming pool, to dispense in the water a soluble solid material carried by the dispenser. The dispenser includes a flotation element from which an apertured receptacle is supported below the water. The receptacle is divided into separate compartments. A single tablet of water soluble material is located within each compartment so that the tablet segregated from the other tablets to expose its maximum surface areas to the surrounding water. The dispenser may be made of two identical integral half sections of molded plastic material which are locked together to lock the tablets within their individual compartments. After dissolution of the tablets, the dispenser may be discarded and replaced with another.

Abstract: A chlorinator is used in a swimming pool system having a filter assembly and a pump for circulating water from the pool through the filter assembly and back to the pool. The chlorinator comprises a housing which defines therein a selectively-openable airtight chamber adapted for receiving therein a quantity of water-soluble dry chlorine material. A water inlet port opens to the chamber essentially at the bottom end thereof, and a separate water outlet port opens from the chamber also essentially at the bottom of the chamber. The inlet port is adapted for connection thereto of an adjustably valved duct by which water to be chlorinated can be applied to the inlet port. A check valve is coupled to the outlet port to prevent water flow through the outlet port to the chamber. The chlorinator is connectible in a pool system in parallel to the filter assembly, for example.

Abstract: An apparatus and method for the controlled chlorination of a water supply in which an alkali metal salt of dichloroisocyanuric acid is dissolved to form a concentrated chlorine solution that is slowly released into the water supply. The apparatus contains an internal standpipe, open to the water supply at its bottom end and having water inlet apertures and solution metering apertures in its wall. The natural circulation of water in the standpipe through the solid dichloroisocyanurate charge contained in the apparatus results in chlorination of the water supply at a rate controlled by the size and number of solution metering apertures.
