    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: 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).

    摘要: The current invention is a cable tether for computer and adapter security and theft Prevention. The cable tether has one or two loops at each end of the cable with a crimp-able metal sleeve. The end of the cable is attached to the sleeve forming the end of the loop while the cable loops back through the sleeve forming an adjustable loop. This end of the cable can slide within the sleeve. The loop is placed around the item to be protected or secured and cannot be removed. The loop is then pulled tight by pulling the cable through the sleeve. Once it is tight enough that sleeve is crimped against the cable holding it in place and forming a secure loop. This can be done at the other end to secure the item to a base, table or computer protecting it from getting lost or taken.

    摘要: A circuit breaker is disclosed which has first and second electrodes that can be contacted to complete a circuit or withdrawn from each other by some suitable mechanism to break the circuit. During breaking of the circuit, an electric arc is created. The circuit breaker includes means for providing gas pressure below atmosphere around the electrodes, at least at the time the arc is struck. The circuit breaker also includes a shield arranged in proximity to the electrodes which is ablated by the action of the arc. The shield's arrangement and material are chosen such that, when ablated, the shield releases gas to assist in extinguishing the arc.
