Abstract:
A filter subassembly is disclosed. The filter subassembly includes an end cap connected to a ring of memory material. The end cap includes a tube-shaped body, a first ring-shaped body, a second ring-shaped body and a third ring-shaped body. The tube-shaped body is defined by an inner radial surface, an outer radial surface, a first axial surface and a second axial surface. The inner radial surface defines a passage extending through the tube-shaped body. The first ring-shaped body extends axially away from the first axial surface of the tube-shaped in a first axial direction. The second ring-shaped body extends axially away from a second axial surface of the tube-shaped body in a second axial direction that is opposite the first axial direction. The third ring-shaped body extends axially away from the second axial surface of the tube-shaped body in the second axial direction that is opposite the first axial direction. Each of the first ring-shaped body, the second ring-shaped body and the third ring-shaped body are defined by an inner radial surface, an outer radial surface and an axial surface that connects the inner radial surface to the outer radial surface. One or both of the first axial surface of the tube-shaped body and the inner radial surface of the first ring-shaped body is disposed adjacent the ring of memory material. The second axial surface of the tube-shaped body, the inner radial surface of the second ring-shaped body and the outer radial surface of the third ring-shaped body collectively define a ring-shaped filter media receiving channel. A filer assembly is also disclosed. An assembly is also disclosed. A filter is also disclosed. A method is also disclosed.
Abstract:
Crankcase ventilation filter assemblies, components thereof, features thereof, and methods of assembly and use are described. An example assembly is characterized in which the assembly includes a housing having an access cover and a base, and a filter cartridge is configured to sealingly engage both the access cover and the base, in preferred manners.
Abstract:
A completely biodegradable cartridge for a water filter that can replace traditional non-biodegradable cartridges. The cartridge may also include one or two caps also made from biodegradable material.

Abstract:
A HIGH FLOW MOLDED ELEMENT FORMED OF UNIFORM DIAMETER RESIN COATED VISCOSE RAYON FIBERS IS USED IN A PARALLEL DUAL MEDIA-DUAL FLOW FILTER TO REMOVE PARTICLES ABOVE A PREDETERMINED SIZE. THE ELEMENT IS MADE TO A PREDETERMINED SIZE, DENSITY, POROSITY, AND FLOW RESISTANCE AND BEING ESSENTIALLY RIGID IT RESISTS UNLOADING. IT MAY BE CONICALLY SHAPED TO HAVE A SUBSTANTIALLY UNIFORM RATE OF FLOW OR INTERNALLY FLOCKED TO PROVIDE MORE UNIFORM POROSITY. AN END CAP MAY BE ADHERED TO THE ELEMENT AS A SUBSASSEMBLY AND THE INLET AND OUTLET FACES ARE PREFERABLY SPACED FROM ADJACENT PORTIONS OF THE HOUSING TO INSURE FLOW TO THE ENTIRE AREAS OF THESE FACES.
