Filed:

Oct 15, 2004

Appl. No.:

10/965973

Inventors:

Philip Yee - Stockton CA, US
Skipper Yee - Stockton CA, US

International Classification:

B01D 35/147

US Classification:

210090000, 210323200, 210456000

Abstract:

A filtering apparatus comprising an elongate container body, an inlet, an inlet reservoir, an outlet, an outlet reservoir, and at least two filter elements, wherein each filter units contains two or more space-apart and co-axially stacked filter elements encased in a cylindrical-shaped filter cartridge. Contaminated fluid flows from the inlet, through the perforations located on the inlet reservoir separator, and into the elongate container body. Fluid flows into the filter units through perforations in the filter cartridge and the open ends of the filter cartridge. The filter units use an opposed axial flow method to draw the fluid through the filter elements. The filtered fluid flows through a perforation in the axial conduit, passes through the axial conduit outlet into the outlet reservoir. The filtered fluid then exits through the outlet. The present invention may be used in operation with a motor and pump to filter large flow rates and volumes of contaminated fluid.

Appl. No.:

7/328978

Inventors:

Skipper K. Yee - Stockton CA

International Classification:

B01D 2708

US Classification:

210249

Abstract:

A filter and bracket apparatus includes a filter element (8) mounted in a filter container (10) on a base (40). The filter base is supported in one of two operating positions by a bracket (100) which has two extending fingers (102) each having a pair of prongs (108, 110) thereon. The filter base has a pair of extending ears (44) which interact with the bracket's prongs to support the filter alternatively in an upright or an inverted position. The invention also relates to a method for changing an oil filter without disconnecting the fluid conduits delivering fluid to and receiving fluid from the filter.

B01D 2708

US Classification:

210167

Abstract:

A portable filtering apparatus with improved canister and filter cartridge design is described for remotely filtering by continuous recycling a variety of solvents and lubricating fluids from machinery reservoirs without requiring the halting of machinery operation or need for emptying said reservoirs to replace the solvents or fluids therein, said filter cartridge being replaceably removable from the canister for complete disposal along with its trapped contaminates preferably by incineration.

Skipper K. Yee - Stockton CA

International Classification:

B01D 2704

US Classification:

210316

Abstract:

An axial oil filter including at least one pair of axially aligned filter elements includes an elongate filter body and a removable filter cartridge. The filter elements are mounted on an axial conduit which is a part of the filter cartridge, and the filter cartridge placed in the filter body so as to define upper and lower chambers, and a bypass flow path between the upper and lower chambers. Fluid to be filtered may flow into either of the chambers and will flow upward through the lower filter element and downward through the upper filter element. The filtered fluid is collected from a passage defined by a screen between the two filter elements, and passes outward from the filter through the outlet port.
