Patent number: 7316778Abstract: An improved oil conditioning filter, for use with an internal combustion engine, includes a mechanically active filter element and a chemically active filter element having a reactive basic conditioner therein. The reactive basic conditioner is provided to counteract acidic combustion products in lubricating oil in an internal combustion engine. In a preferred embodiment of the invention, the chemically active conditioning agent is provided in a plurality of pellets disposed within the oil filter housing. The pellets may be bonded together to form an integral porous filter element having spaces defined between the pellets thereof.

Patent number: 6656360Abstract: A unique filtration device (10) which removes metal ions from a contaminated aqueous stream through the use of partially hollow wicking fibers (20) impregnated with a selected liquid (18) which can capture the metal ions in the aqueous stream. The wicking fibers (20) are formed into a filter element (12) which extends from a chamber (16) through which the aqueous stream is directed into a chamber (18) wherein the unwanted metal ions are removed from the extracting liquid (18). The wicking fibers (20) include internal longitudinal cavities (22) each with a relatively small longitudinal extending opening (24). The wicking fibers (20) are filled with the selected liquid extraction (18) which remains within the fiber through capillary action by which capillary action the individual wicking fibers (20) rapidly draw the selected liquid,(18) with which they comes into contact, through the internal cavities (22).Type: GrantFiled: October 14, 1997Date of Patent: December 2, 2003Assignee: AlliedSignal Inc.Inventors: Ronald Paul Rohrbach, Gordon William Jones, Peter Unger, Daniel Bause, Russell Dondero, Lixin Xue
