摘要： A backflush conduit (38) for an automatic backflushing filter (10) having an inlet portion (62) with a symmetrical converging bell-shaped cross section, an outlet portion (60) with a generally cylindrical shape, and a converging and reorienting transition portion (64) connecting the inlet and outlet portions. Converging convex surfaces (66, 68) of the bell-shaped opening (62) smooth fluid inflow and prevent fluid separation. The transition portion (64) interior contour redirects the fluid flow without inducing turbulence, resulting in more efficient backflushing to clean the entire filter element (26) even at small element pore sizes.

摘要： A programmable aerator cooling system for pools or spas is provided. The system selectively operates one or more aerator jets in a pool or spa to cool water in the pool or spa to a desired temperature. The system includes a microprocessor-based controller connected to a valve actuator for selectively actuating the one or more aerator jets, and one or more sensors. The sensors could include a water temperature sensor, and optionally, an ambient air temperature sensor and an ambient humidity sensor. The controller includes a user interface for allowing a user to interact with one or more stored control programs for controlling the water temperature of a pool or spa. Based on pool water and ambient conditions, the controller can activate the one or more aerators during optimal ambient conditions to cool the pool water.

摘要： A device for filtering fluid includes a hollow housing (10) having a fluid inlet (26) and a fluid outlet (28). A filter element (50) formed of fluid permeable material is disposed within the housing (10) for filtering fluid entering the fluid inlet (26), the fluid passing through the element (50) and out the fluid outlet (28). The element has a generally cylindrical configuration with the permeable material forming a plurality of elongated, radially extending pleats (98). The pleats are supported by spacers (81) having a plurality of blades (102) attached to a web (106) with channels (104) therebetween. The element (50) is used as a septum for supporting a diatomaceous earth precoat. A regeneration piston (76) creates fluid flows within the filter that cause the element (50) to flutter, thereby displacing the diatomaceous earth precoat from the septum for regeneration.

摘要： A system and method are provided for controlling water temperature in a body of water. The temperature control system includes a processor, a user interface for receiving a desired temperature and a desired time for reaching the desired temperature, a sensor interface for receiving sensor information from one or more sensors, and an actuator interface for controlling a plurality of heat sources. The processor determines one or more optimal heat sources for heating the body of water to the desired temperature by the desired time. The processor controls the one or more optimal heat sources through the actuator interface and periodically polls the sensor interface to determine whether changes in the operating environment require additional or alternate heat sources to be activated to ensure that the body of water is heated to the desired temperature by the desired time.

摘要： A fluid filter (10) having a hollow, molded, plastic housing (12) with an open end, a fluid inlet port (20) and a fluid outlet (22). An internally threaded, plastic, molded cap (14) is threadedly received on the housing (12) via mating external threads (56, 58) for sealing the open end of the housing (12). A cap seal (60) prevents fluid contamination of the threads (56, 58). A removable filter element (38) is contained within the housing (12) between the fluid inlet (20) and the fluid outlet (22). A molded, resilient, plastic retainer (44) captured between the cap (14) and the filter element (38) retains the filter element (38) in position within the filter (10). If the filter element (38) is of a bag filter type, as compared with a filter cartridge type, the retainer (44) has a plurality of resilient legs (46) which press down upon a bag mouth seal (40) forcing it into contact with a flared mouth of the bag support (28).
