Abstract: The present invention includes a method for filtering flowing fluid so as to remove undesirable particulates and bacterial constituents and fluid filters for performing the method. The method comprising providing an enclosed channel for fluid flow and passing the fluid flow through a filter material (120, 122) disposed within the channel and the filter material comprising a metal alloy consisting primarily of copper (Cu) and zinc and being metal fibers having an average diameter from 12 microns to 150 microns, contact of the fluid with the fibers of the metal fiber wool (120, 122) providing a bactericide effect and inhibiting further propagation of bacteria and particulates from flowing through the filter material. The fluid filters may be a radial-flow fluid filter (10) comprising a multi-perforated pipe (14) and a plurality of overlapping layers of strips of fibrous metal wool (12) including metal wool containing copper (Cu), or an in-line flow fluid filter comprising a fluid channel (124, 222) and a filter material (120, 122) disposed within the fluid channel ((124, 222), wherein the filter material (120, 122) comprises a metal fiber wool of a metal alloy consisting primarily of copper (Cu) and zinc and being metal fibers having an average diameter from 12 microns to 150 microns. A multi-perforated shell (20) of the radial flow fluid filter (10) may have an inner diameter approximately equal to outer diameter of an outermost layer of wool and a tubular metal mesh encompassing the exterior of the pipe (14) between the pipe (14) and the innermost layer of metal wool (12), the tubular mesh being a woven mesh of stainless steel. The metal of the fiber wool layers (12) is a brass alloy having between 50-90 weight % copper and from 10-50 weight % zinc, a preferable density in a range between 0.4 g/cm 3 to 2.5 g/cm 3 , a more preferred density in a range between 0.5 g/cm 3 to about 1.5 g/cm 3 , and a most preferred density of approximately 0.8 g/cm 3 .

Abstract: Expansion resistant filter cartridge assemblies are provided that facilitate filtering of strong solvent solutions. The filter cartridge assemblies (120) generally include a cylindrical filter element defining an outer periphery, an inner periphery and opposed end surfaces, a perforated cage (122) operatively associated with the outer periphery of the filter element, a perforated core operatively associated with the inner periphery of the filter element and having opposed ends and a predetermined length, and an end cap operatively associated with each of the opposed end surfaces of the filter element and bonded to each end of the core. The perforated cage generally includes an expansion region (122c) of about 2.5 % to about 4 % of the total length of the filter cartridge, e.g., a region of axial discontinuity or a plurality of angular struts, to accommodate swelling and/or dimensional expansion of the cage without adversely affecting the integrity of the filter cartridge assembly. Alternatively, an expandable net material may be provided to accommodate expansion/swelling thereof. The core of the filter cartridge assembly is advantageously fabricated from material(s) that resist swelling/expansion when exposed to strong solvent solutions, e.g., glass filled polypropylene, stainless steel and/or fluorinated aliphatic hydrocarbon.

Abstract: A fluid filter (10) includes a cylindrical pleated filter media (12) disposed around a central perforated support core (33) or self-supporting. An outer support sleeve (14) comprising an extruded nylon, diamond-shaped mesh is streched across the pleated media, and elastically conforms to the pleat peaks (19) to structurally retain the pleats (18) of the pleat peaks in fixed relation to one another without mechanical or chemical connection to the pleats. Preferably, the support layer (14) has a strand angle between 60 and 90 degrees, and a strand density sufficient to mark the element with appropriate identification indicia (36). End caps (16, 17) are disposed at opposite ends of the fluid filter (10). The cylindrical filter media (12) is radially compressed through a conical tool (40) into the outer sleeve (14). An inner support core (33) or mandrel (70) with a second conical tool (72) is then forced into the cylindrical filter media to enlarge the media such that the outer sleeve (14) elastically stretches and conforms to the pleat peaks (19).

Abstract: A filter for filtering a highly viscous material comprises a filter element including a glass fiber filter medium, preferably resin-bonded, having upstream and downstream sides and a polymeric mesh situated on at least one of the upstream and downstream sides of the filter medium, and preferably on both sides of the filer medium. A non-woven sheet, such as a cellulose paper sheet, may be disposed between the downstream side of the filter medium and the downstream polymeric mesh. The filter element is typically cylindrical and longitudinally pleated to maximize the filtration area in as small a volume as possible. Also provided is a method of filtering a highly viscous material, particularly magnetic coating mixes.
