    摘要： A nonwoven filter media or mat (10) formed from a plurality of elongated generally hollow fibers (20) each having an internal cavity (22) which has an opening (24), smaller than the cavity width, to the fiber (20) surface and each retaining within the internal cavity (22) an electrically conductive material. The electrically conductive material can be a large number of relatively small conductive solid particles (18). The small solid particles (18), which can be graphite are permanently entrapped within the longitudinal cavities (22) of the fibers (20) without the use of an adhesive. The electrically conductive material can also be a selected liquid. In the case of a liquid, the wicking fibers (20) are filled with the selected conductive liquid through capillary action by which the individual wicking fibers (20) rapidly draw the selected electrically conductive liquid, with which they come into contact, through the internal cavities (22). The electrically conductive material, either solid particles or a 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).

    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 carbon powder (18) or zeolites and formed into a fiber filter (12) with a selected chemisorptive liquid applied to one side of the fiber filter (12) and large carbon particles (19) applied to the other side of the fiber filter (12). The air stream to be cleaned is directed through filter element (12) which can capture the gas phase contaminants. The wicking fibers (20) include internal longitudinal cavities (22) filled with the fine carbon powder (18) and each having a relatively small longitudinal extending opening (24). The wicking fibers (20), to a shallow depth on one side of filter (12), 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 carbon powder (18) or zeolite powder remain within the wicking fiber cavities (22) and generally do not enter the space between the wicking fibers yet through the longitudinal openings (24) the fine carbon particles (18) and the chemisorptive liquid are in full fluid communication with the air stream flowing past the fibers (20).

    摘要： An improved windshield wiper system having a cumulative ozone indicator (20) disposed in proximity to a wiper blade (10) which gives a visual cue when the wiper blade (10) should be replaced. The exposure to a predetermined amount of ozone causes the indicator (20) to change its color and thus communicate to the vehicle operator that it is time to change wiper blade (10). Rather than changing color the indicator (20) can be a pop up device which can be observed by the vehicle operator. To allow a reaction with ozone but to prevent damage from contact with a liquid the indicator (20) is covered with a gas permeable and liquid impermeable material.

    摘要： Modification, neutralization and/or decontamination of airborne biological and/or chemical contaminants from a breathable atmosphere by subjecting the breathable atmosphere to a filter which is formed from a plurality of polymeric multilobal fibers. These fibers include a central core with T-shaped lobes projecting therefrom, wherein each T-shaped lobe has a leg and a cap. The lobes define a longitudinally extending internal cavity between two adjacent legs that extends the entire length of the fiber. The filter is impregnated with a biological and/or chemical decontamination reagent for chemically modifying, neutralizing and/or decontaminating airborne biological and/or chemical contaminants from a breathable atmosphere. A filter projection preferably extends into an external reservoir containing a supply of biological and/or chemical decontamination reagent. This configuration increases the capacity and efficiency of the filter, and causes a lower pressure differential across the filter.

    摘要： A filter material includes a filter pad made from a thin, nonwoven fiber mat which has been accordion-pleated, compressed into a unit having a large number of substantially parallel interconnected filter strips, and treated to retain the filter strips in substantially parallel relation to each other. In a preferred embodiment, activated carbon particles are operatively associated with the filter pad. Selected fibers of the nonwoven fiber material are hollow fibers, each having an outer surface, a hollow internal cavity, and an extended slot formed therein, between the hollow internal cavity and the outer fiber surface. Carbon particles may be located between selected filter strips, and additional carbon particles may be disposed within the cavities of the hollow fibers. Methods of forming the filter material, and a filter element made with the filter material are also disclosed.

    摘要： A battery separator, for placement between conductive plates within a battery, includes a non-woven fiber mat made up of one or more nonwoven fibers, which have a specific cross-sectional shape and exhibit a microcapillary action. The fibers are preferred to be made of a thermoplastic selected from the group consisting of polyolefins, fluoropolymers, polyimides, polysulfones, polyesters, polyamides, and mixtures thereof Each of the fibers includes an outer surface, a hollow internal cavity, and an extended slot. The hollow internal cavity communicates with the outer surface by way of the extended slot. Capillary forces within the fibers are greater than those on the fiber surface, such that a liquid electrolyte readily moves through the interior of the fiber via a wicking action. As a result, the battery separator tends to direct fluid to adjacent battery plates even when an electrolyte level, within the battery, drops below the tops of the plates.

    摘要： A unique filtration method and device (10) which continuously removes several gas phase contaminants from an air stream through the use of partially hollow wicking fibers (20) impregnated with a selected liquid which can capture the gas phase contaminants. The wicking fibers (20) are generally disposed parallel and are formed into a filter element (12) which extends from the air stream to be cleaned into another air stream which can strip and carry away the unwanted gas phase contaminants. The gas phase contaminants are conveyed to the stripping air stream by a concentration factor induced molecular migration. The air stream to be cleaned is directed through a compartment (16) across which the filter element (12) extends so the complete air flow is through filter element (12). Filter element (12) also extends into another compartment (18) through which the stripping air stream flows. 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 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).
