20100270337 | ADJUSTABLE FLOW NOZZLES - Adjustable nozzles are disclosed. Nozzles of the present invention include an adjustable component for controlling the water flow through the nozzle. Instead of disassembling the nozzle, a tool may be used to adjust the adjustable component. For example, the adjustable component may be adjusted longitudinally with respect to the axis of the nozzle or rotationally using the tool, thereby increasing or decreasing the volume, velocity and distance of the water stream exiting the nozzle. | 10-28-2010 |
20090294381 | METHODS FOR CONTROLLING PH IN WATER SANITIZED BY CHEMICAL OR ELECTROLYTIC CHLORINATION - The invention relates to the control of pH in water where hydroxyl ions are being produced by adding to the water an amount of transition metal salt sufficient to bind with hydroxyl into a slightly soluble or insoluble reaction product, thereby removing sufficient hydroxyl ion from the water to lower the pH thereof. This technique is particularly suitable for pH control in pool or spa water that is sanitized using chemical or electrolytic chlorination, where the sanitation process causes the pH in the water to rise. The invention also relates to apparatus for dispensing water treatment materials to water, and to methods for controlling phosphate levels and algae in water. | 12-03-2009 |
