摘要： A gas mask having a filter canister mount including an inhalation valve and a self-sealing mechanism that prevents air inflow when a filter canister is removed from the canister mount. In one embodiment, the self-sealing valve includes an elastomeric diaphragm mounted in the inlet port and includes a hinge and a skirt, the skirt having a sealing surface that is biased into contact with a valve seat. The filter canister includes a projection adapted to act on the hinge to pivot the skirt away from the sealing surface as the canister is fitted to the canister mount. In one embodiment, the canister comprises a stacked-radial-flow arrangement of particulate and carbon filtration media. In one embodiment, the gas mask includes a visor having a pair of spaced optical panels with a hinge mounted therebetween for relative rotational movement.

摘要： The present invention relates generally to an environmental control unit for use in air handling systems that provides highly effective filtration of noxious gases (such as ammonia). Such a filtration system utilizes novel metal-doped silica-based gels to trap and remove such undesirable gases from an enclosed environment. Such gels exhibit specific porosity requirements and density measurements. Furthermore, in order for proper metal doping to take effect, such gels must be treated while in a wet state. The combination of these particular properties and metal dopant permits highly effective noxious gas filtration such that uptake and breakthrough results are attained, particularly in comparison with prior silica gel filtration products. Methods of using and specific filter apparatuses are also encompassed within this invention.

摘要： An environmental control for use in air handling systems that are required to provide highly effective filtration of noxious gases is provided. In one embodiment, a filtration system utilizes a novel combination of at least one metal-doped silica-based gel and zeolite materials to trap and/or modify, and remove such undesirable gases (such as ammonia, ethylene oxide, formaldehyde, and nitrous oxide, as examples) from an enclosed environment. The gel component exhibits specific porosity requirements and density measurements; the zeolite component is generally acidic and is preferably not reacted with any salts or like substances. The novel combination of such gels and zeolites permits highly effective noxious gas filtration over a wide range of known toxic industrial chemicals such that excellent breakthrough results are attained, particularly in comparison with prior media filtration products. Also included is the presence of an oxidizing agent on the gel materials to aid in capturing nitrogen dioxide and preventing conversion of such a product to NO. Methods of using and the application within specific filter apparatuses are also encompassed within this invention.

摘要： A regenerable filter system includes a flow path along which a stream of fluid flows between an inlet and an outlet. A first filtering unit is located in the flow path. The first filter unit includes first and second regenerable filter beds, wherein each bed has a first adsorbent for removing a first contaminant from the fluid stream. A first valve is located between the inlet and the first and second filter beds for selectively directing the fluid stream through one of the first and the second filter beds. The other of the first and second filter beds is removed from the flow path. A second filtering unit is located in the flow path between the first filtering unit and the outlet. The second filtering unit includes third and fourth regenerable filter beds for removing a second contaminant from the stream of fluid. A second valve is located between the first filtering unit and the third and fourth filter beds for selectively directing the stream of fluid through one of the third and fourth filter beds, wherein the other of the third and fourth filter beds is removed from the flow path. A controller operates the first valve such that the stream of fluid is directed through one of the first and second filter beds. The second valve is so operated that the stream of fluid is directed through one of the third and fourth filter beds. The first and second filter beds are cycled independent of one another.
