Abstract: 1. CONTAINER FOR DISPENSING WATER SOLUBLE SOLID TREATING AGENT AND ADAPTED TO BE PARTLY IMMERSED IN WATER TO BE TREATED, SAID CONTAINER COMPRISING A CYLINDRICAL WALL HAVING AN IMMERSIBLE REDUCED DIAMETER LOWER PORTION INCLUDING PLURAL CIRCULARLY SPACED PORT MEANS HAVING KNOCKOUT CLOSURES TO PASS WATER INTO SAID CONTAINER, A PLURALITY OF ANNULARLY SEGMENTED RIBS ARRANGED TO ENGAGE STRUCTURE RECEIVING AND SUPPORTING THE CONTAINER IN LOWER PORTION IMMERSED CONDITION, SAID RIBS LYING IN VERTICALLY SPACED RADIAL PLANES WITH THEIR CORRESPONDING SEGMENTS, IN VERTICALLY ALINED AND IN SPACED RELATION TO DEFINE INCREMENTAL IMMERSION ADJUSTMENTS FOR SAID CONTAINER LOWER PORTION IN THE WATER PLURAL VERTICALLY EXTENDED AND CIRCULARLY DISTRIBUTED SPACES WHICH UPON BODILY ROTATION OF THE CONTAINER PASS AND PERMIT RELATIVE VERTICAL MOVEMENT OF THE RIBBED AND LOWER PORTION OF THE CONTAINER WALL AT SAID STRUCTURE, AND A STOP RIB FORMED INTEGRALLY WITH SAID SEGMENTED RIBS AND EXTENDING PARALLEL WITH THE CONTAINER AXIS TO BE ENGAGED BY THE SUPPORTING STRUCTURE TO ARREST ROTATION OF THE CONTAINER.

Abstract: Filter for swimming pool water in which multiple operational modes including filtration, backwash and rinse modes are achieved with a valve structure affording positive sealing during operation, positive locking into mode, and adjustment between modes without frictionally wearing critical seals in the valve, and positive sealing at the waste discharge against air flow into the filter. The filter valve structure further employs large ports and direct flow passages to provide low pressure drop, even at very high flow rates through the filter, and a novel water distributor to avoid turbulence and undue disruption of the filter medium during filtration.
