    Abstract: A respirable one-ply, two-ply or multi-ply barrier fabric including one web comprising an electrostatically charged melt blown fibers nonwoven or a nanofiber/melt blown fibers nonwoven having a weak cationic emulsifier to reduce surface energy of the fibers so as to minimize penetration and wetting by oily mists and to thereby preserve the effectiveness of electrostatic charges applied to fibers. Also disclosed is a two-layer or multi-ply barrier fabric which has at least one barrier fabric layer which is impermeable to liquids such as water and body fluids, but which allows the transport of moisture vapor through the micropores or by chemical absorption of water through a monolithic membrane, which may have additional barrier layers to include melt blown and nanofiber/melt blown composites. One or more layers of the respirable barrier fabric or the moisture transporting microporous (MP) or monolithic (ML) films or combination thereof may contain an antimicrobial agent, fluorochemical or other protective finish, as well as any of the layers of the respirable filter fabric or any of the layers of the filter ensemble as well as any layer of the liquid barrier moisture transporting barrierfabrics. Furthermore, the protective fabrics may contain a porous or absorbent fabric or film on the body side for enhanced thermal comfort, and other additives may be included in the fabric ensembles such as activated carbon particles, or activated carbon particles, or other sorbents, or superabsorbents o to absorb odors or toxic chemicals.

    Abstract: A high density inhibited red fuming nitric acid oxidizer gel is disclosed ich results in an improvement from 0.5% to about 1.0.% in the impulse over a baseline formulation containing 14% nitrogen tetroxide. An improvement from about 3.0% to about 6.0% is achieved in the density impulse baseline formulation. The higher density inhibited red fuming nitric acid is derived by adding from about 15 percent by weight to about 45 percent by weight percent of nitrogen tetroxide to nitric acid in an amount from about 80 percent by weight to about 40 percent by weight. The other ingredient of the oxidizer gel comprise a gellant of about 0-10 percent by weight, water from about 0-4 percent by weight, and an inhibitor agent of about 0-1 percent by weight. IRFNA is inhibited with phosphoric acid, iodine compounds, or hydrogen fluoride which is present in the oxidizer gel as an additive. The higher density IRFNA oxidizer gel or liquid can be used in airbreathing propulsion systems; a bipropellant formulation is used to provide variable thrust. The oxidizer can also be used with air turbo rocket propulsion systems to augment air combustion with fuel gases. It can be used in a liquid or gel/solid system wherein the oxidizer is sprayed in contact with a solid propellant.

    Abstract: Pt catalyst on a substrate provides an air purification particularly for carbon oxide contained in the inhaled air is caused to react with air oxygen on the surface of carbon oxide catalysts and thus removed. But it is desirable for many air filter applications to eliminate, in addition to CO, other harmful gases from the air also. The Pt catalyst used as gaskmask filter material offers, particularly, but little protection additionally against acid gases. Due to an additional impregnation with the oxides of amine-forming heavy metals, the separating powers for acid gases is increased extraordinarily without reducing the capability of the Pt catalyst to oxidize CO catalytically. There even results an intensification of the respective effectiveness.
