    摘要： 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). The liquid extrant (18) remains within the wicking fiber cavities (22) and generally does not enter the space between the wicking fibers (20) yet through the longitudinal openings (24) the liquid (18) is in full communication with the metals contaminated aqueous stream flowing through the filter (12) and past the individual fibers (20).

    摘要： A fluid filter increases the useful life of the filtered fluid by removing contaminants therefrom, and may optionally provide for in-line delivery of additives to the filtered fluid. The filter may be an oil filter, a fuel filter, or other fluid filter. The fluid filter includes a casing which defines a hollow space therein, a mechanically active filter element within that space, and a chemically active filter element also retained within the hollow space proximate the mechanically active filter element. The chemically active filter element includes a nonwoven web made up of a plurality of fibers. Each fiber has a longitudinally extending internal cavity formed therein, and a corresponding longitudinally extending slot opening from that internal cavity to the outer surface of the fiber. Preferably each fiber as multiple lobes extending radially outwardly from a central stem, and each lobe cooperates with an adjacent lobe to define a longitudinally extending internal cavity and a corresponding slot therebetween. In order to remove contaminants or to supply additives to lubricating oil, the internal cavities, of each of the chemically active filter fibers, are supplied with a chemical reagent therein.

    摘要： 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. The pellets are made of a mixture including a polymeric binder and the chemically active conditioning agent, in a defined weight ratio and in a narrow range of particle sizes. The chemically active filter element reacts with acids present in the oil to form a product which may be filtered out of the oil. The pellets are made either by a hot extrusion process or by a solvent process.
