    Abstract: A filter element assembly has at least two cylindrically shaped and concentrically arranged filter media sleeves each connected at one end thereof to an inlet plate and each connected at the other end to a closed end terminal plate. Openings are provided in the inlet plate to permit entry of liquid to be filtered into the annular space between the filter sleeves. The closed end terminal plate prevents flow of unfiltered liquid from the annular space between the sleeves so as to force the liquid through the porous media of the sleeves to effect filtration.

    Abstract: A single cartridge filter housing assembly for the filtration of etching liquids, deionized water, slurries and other liquids used in the semiconductor, pharmaceutical and chemical industries. It comprises a bottom housing and a top housing with an O-ring in between and a nut ring engaging top and bottom housings in order to compress the O-ring thus forming a sealed cavity for the cartridge. The bottom housing holds the nose of the cartridge in a concentric recess and holds the cartridge top centered by several radial protrusions in its mouth. An inlet and an outlet at the bottom of the bottom housing for the liquid to be filtered are coaxial for easy plumbing connections. The top housing carries a vent tube to use the air within to stabilize the liquid level in spite of pressure variations because of pump action.

    Abstract: A fuel filter assembly (10) for filtering diesel fuel includes a filter head (12), a spin-on replaceable element (13) and a collection bowl (15) removable from the element. The element includes a casing (52 ) with a turned-in edge portion at a lower end. An adaptor ring (69) is supported on said edge portion inside the element and includes an annular threaded portion (71). The collection bowl has an outer peripheral wall (74) with an annular threaded portion engaging the threaded portion of the adaptor ring. The outer peripheral wall of the bowl has an annular shoulder abutting the turned-in edge portion of said casing to damp said casing between the adaptor ring and the bowl, when the bowl is attached to the element. The adaptor ring has a plurality of spaced ribs (70) with projections that extend upward and radially outward to maintain the filter medium (55) spaced from an inner wall surface of the casing. A resilient member (68) holds the filter medium between a top plate (62) and the adaptor ring.
