Abstract: A method of applying an integral sealing member to a shaped surface which in its operative environment is to be disposed in sealed relationship with another surface and the resulting products. The method comprises dispensing a composition adapted to be cured to form said sealing member onto a work surface adapted to be adjusted to a desired configuration, partially curing said composition such that it does not flow, adjusting the disposition of said work surface bearing the partially cured composition such that said shaped surface to which the sealing member is to be integrally bonded may be disposed along said work surface, positioning said shaped surface along said work surface such that said shaped surface is at least in contact with said partially cured composition, completing the curing of said composition and removing said shaped surface with said sealing member integrally bonded thereto from said work surface.

Abstract: A fluid filter cartridge having spaced inner and outer perforated walls forming concentric chambers. End plates cap the ends of the walls with one of the end plates being centrally apertured to provide a passageway in communication with the inner wall chamber. A filtering media, preferably of cotton and wood fibers, is packed in the chamber between the inner and outer walls.The improvement comprises a plurality of surface deformations in one of the walls, preferably the outer wall, extending into the filtering media toward the other wall. The surface deformations engage and compress the filtering media contiguous thereto to provide filter flow paths from the one wall to the other of a higher density than that of the uncompressed filtering media.
