摘要： A filter device and technique are described which rely on absorption rather than adsorption for the removal of gas phase contaminants. A filter media is composed of wicking fibers which are impregnated with any of a variety of liquid phase absorbing systems made from the combination of a carrier liquid and soluble complexing/degrading agent or agents. The wicking fibers may be connected to an external reservoir which can be used to supply fresh absorbing fluid to the filter media giving them a potentially inexhaustible capacity. The filter media may be made from any of a variety of fibers which can rapidly transport a liquid phase by the nature of either their geometry or their chemical composition. Geometries may include multilobal cross-sectional configurations, porous hollow fibers, porous or striated fibers or tightly bundled microfibers, all of which exhibit the property of wicking fluid from an external source.

摘要： A filter device and technique are described which rely on absorption rather than adsorption for the removal of gas phase contaminants. A filter media is composed of a plurality of wicking fibers each of which comprising a strand with a hollow region impregnated with any of a variety of liquid phase absorbing systems made from the combination of a carrier liquid and soluble complexing/degrading agent or agents. Each strand has a slot which connects the interior hollow region with an external surface. Capillary forces act on the carrier liquid such that the external surface is substantially dry and no appreciable adsorption of contaminates occurs on the external surface which would restrict the flow of an air stream through the filter media even after an extended period of use. The wicking fibers may be connected to an external reservoir which can be used to supply fresh absorbing fluid to the filter media giving them a potentially inexhaustible capacity. The filter media may be made from any of a variety of fibers which can rapidly transport a liquid phase by the nature of either their geometry or their chemical composition. Geometries may include multilobal cross-sectional configurations, porous hollow fibers, porous or striated fibers or tightly bundled microfibers, all of which exhibit the property of wicking fluid from an external source.

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 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： 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： 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 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).
