Abstract: This invention comtemplates a new and novel filtering device that comprises a plurality of parallel filter elements with means within the device for backflushing two or more of the filter elements without removing the elements from the device and while the device is being operated onstream and filtering. The backflushed fluid used to clean the elements is isolated from the primary fluid stream and discharged from the device.

Abstract: This invention comprehends a new and unique means for preventing the crowns (forward projections of the pleats) of a backflushable filter element from splitting due to the cyclic action that is experienced during cleaning and backflushing. In one embodiment, a plurality of spacers, preferably wedge shape, is positioned between the outwardly projecting pleats of the filter media thereby preventing the splitting thereof. A plurality of spacers may also be placed between the inwardly projecting pleats to provide additional support during the cleaning and backflushing cycle. In another embodiment a ring is placed adjacent the inwardly directed pleats and the inner end cap lip; this also prevents splitting of the crowns when the filter element is subjected to the cyclic action of cleaning and backflushing.

Abstract: A prefabricated swimming pool includes a liner and a wall supported by vertical posts. Lip members are arranged between the posts along the top edge of the wall and connected to the posts by brackets. The angles at which the lip members are attached to the posts are adjustable so that the number of posts used to support the wall can be varied, and pools of differing sizes can be constructed using standard components.
