    摘要： A filter, for use in removing residual fuel vapors from within an engine's intake system, includes a filter element having a plurality of fibers, for placement in communication with an intake air flow passage. Each of the fibers has an internal cavity formed therein, and a longitudinally extending slot formed therein extending from the internal cavity to the outer fiber surface. The filter also includes a hydrocarbon-absorbing material disposed within the internal cavities of the fibers. The hydrocarbon-absorbing material may be a solid material such as, e.g., carbon, or may be a liquid such as a relatively non-volatile organic solvent. Alternatively, the material may be a combined solid and liquid. In one embodiment, each of the elongated fibers includes a central stem and a plurality of lobes extending outwardly from the central stem, with a longitudinally extending slot defined between adjacent lobes. Specific useful filter configurations are detailed.

    摘要： The internal channels (22) of wicking fibers (20) are filled with a selected liquid (18) form of a prepolymerized polymer or monomers and related reagents and then the polymerization reaction is carried out under suitable conditions to form a fiber with desired properties. Fibers with the properties of the formed polymeric products are conveniently obtained thereafter. This provides a convenient way to obtain engineered fibers by directly polymerizing the monomers in the wicking fiber (20) channels (22). The wicking fibers (20) include internal longitudinal cavities or channels (22) each with a relatively small longitudinal extending opening (24). The wicking fibers (20) are filled with the selected liquid through capillary action by which the individual wicking fibers (20) rapidly draw the selected liquid, with which they comes into contact, through the internal cavities (22). The selected liquid remains within the wicking fiber cavities (22) and generally does not enter the space between the wicking fibers yet through the longitudinal openings (24) the liquid is in full communication with the environment surrounding the wicking fiber (20). The formed solid polymer is retained in the channels (22) of the wicking fiber (20).

    摘要： An unique filtration device (10) which removes acidic contaminants such as H2S and SO2 from a fluid stream through the use of partially hollow wicking fibers (20) impregnated with an effective amount of alkaline-generating chemical compounds, preferably also containing an effective amount of a compound with elements from Group II and Group 6-12 in +2 oxidation state, and most preferably also containing an effective amount of solid fine particles (18). A nonwoven filter mat (12) is formed from a plurality of the elongated fibers (20) each having at least one internal channel (22) connected to the fiber outer surface via an elongated opening (24).

    摘要： A unique filtration device (10) which continuously removes gas phase contaminants from an air stream through the use of partially hollow wicking fibers (20) impregnated with a fine solid powder and a selected chemisorptive liquid (18) which can capture the gas phase contaminants. The wicking fibers (20) are generally disposed to extend in the same direction and are formed into a filter element (12). The air stream to be cleaned is directed through filter element (12). The wicking fibers (20) include internal longitudinal cavities (22) filled with a fine powder and each having a relatively small longitudinal extending opening (24). The wicking fibers (20) are filled with the selected contaminant removing chemisorptive liquid through capillary action by which the individual wicking fibers (20) rapidly draw the selected chemisorptive liquid, with which they come into contact, through the internal cavities (22). The chemisorptive liquid and fine powder remains within the wicking fiber cavities (22) and generally does not enter the space between the wicking fibers yet through the longitudinal openings (24) the chemisorptive liquid is in full fluid communication with the air stream flowing past the fibers (20).

    摘要： A unique odor filtration device (10) which continuously removes odor causing gas phase contaminants from an air stream through the use of partially hollow wicking fibers (20) impregnated with a selected liquid (18) which can capture odor causing gas phase contaminants. The odor removing liquid (18) is a chemical composition including sodium permanganate in combination with either sodium carbonate or sodium phosphate. The odor absorbing liquid (18) can include specialized additives such as transition metal salts and other agents such as sodium iodide for additional and broader odor removal coverage. The wicking fibers (20) are formed into a filter element (12) which extends from a chamber (16) through which the air stream to be cleaned is directed into a stripping chamber (19). The odor causing contaminants are conveyed to from chamber (16) to chamber (19) by a concentration factor induced molecular migration. 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 contaminant removing liquid through capillary action by which the individual wicking fibers (20) rapidly draw the selected liquid, with which they come into contact, through the internal cavities (22). The absorption liquid (18) remains within the wicking fiber cavities (22) and generally does not enter the space between the wicking fibers yet through the longitudinal openings (24) the liquid is in full communication with the air stream flowing past the fibers (20).

Preferably, the fibers making up the substrate have hollow internal cavities formed therein, and extended openings formed in the sides thereof in communication with the internal cavities. Preferably, the desiccant composition is an alkali halide or an alkaline earth halide. Most preferably the desiccant composition is selected from the group consisting of lithium chloride, calcium chloride and magnesium chloride.
