  • Publication number: 20040026055
    Abstract: The present invention is drawn to a thermally and structurally stable, noncombustible paper, comprising a dominant amount of aluminosilicate refractory fibers and from 0.2% to 4% by weight of a polymeric binder. The refractory fibers can be substantially from 1 micron to 35 microns in width and from 1 cm to 15 cm in length, though other functional dimensions can be used. Optionally, from 0.1% to 5% by weight of viscose fibers and/or from 0.2% to 5% by weight of silicic acid aquagel can also be present. The papers of the present invention are mat-type papers that can be structurally stable at very high temperatures up to about 1400° C. or more.

  • Publication number: 20040025879
    Abstract: A method and apparatus for protecting humans against hazardous particulate agents such as biological or chemical agents. A special porous cloth contains activated carbon threads that is used as a quick escape mask to cover the mouth and/or nose of a person to protect the person from inhaling hazardous particulates. This simple cloth mask may be designed for short-term emergency respiratory protection and can be particularly convenient for use by people who are in relatively public, enclosed areas (such as in restaurants, bars, or hotel rooms) and who might need to evacuate those areas in a short period of time. The cloth may also be used in other applications, for example, as a tent liner, as a liner for military uniforms or diving suits, or as a water or air filtration device. In addition to protection from hazardous agents, the cloth may sometimes additionally filter out bad odors.
