摘要： The invention disclosed relates to novel branched chain hydroxy-terminated aliphatic azido polymers and copolymers with variable molecular weight (MW) and a single step method for the preparation thereof which involves respectively reacting a high (MW) 0.5-5.0.times.10.sup.6) solid rubbery polyepichlorohydrin (PECH) homopolymer and epichlorohydrin/alkylene oxide copolymer (PEEC), with an alkali metal azide in a suitable organic solvent, in the presence of an initiator at elevated temperature. The MW of the azido product may be controlled by including in the reaction mixture a basic degradation catalyst (such as LiOCH.sub.3 or NaOH) and varying the amount of catalyst. When the reaction is catalyzed, the MW of the product varies within the range 1,000-40,000 and the hydroxyl functionality is 2-10. Uncatalyzed reactions yield products with MW between 40,000 and 200,000 and a functionality of about 10. The branched azido polymers and copolymers yield energetic binders with improved mechanical properties and thermal stability which are useful in rocket propellants and composite explosives formulations.

摘要： A filter canister assembly utilizes a sealant deflector to seal a particulate filter to the canister wall, even after the canister is sealed. The canister housing has a wall and an aperture with a particulate filter disposed therein. The particulate filter has an edge adjacent the wall, and is designed for removing particles of contaminants from a fluid, such as air, passed through the canister. A sealant deflector includes a plurality of vanes standing proud of a support substrate, and is situated between the aperture and the particulate filter and forms a permanent part of the canister assembly. The sealant deflector deflects a sealant in liquid state toward the wall to form a seal between the edge and the wall when the sealant is deposited on the sealant deflector while spinning. This deposits a sealant ring sealing the wall to the edge. The sealant deflector is self-centered under the aperture, by a bow-tie shaped structure of four arms extending outward radially from the sealant deflector connected in pairs by curved braces.

摘要： This invention relates to a multi-layer protective fabric for protective suits used in hazardous or toxic environments. A first layer comprises strips of water and vapor impermeable material, there being a gap between adjacent such strips. A second layer comprises a plurality of strips of a wicking material with each such strip covering the inner surface of a first layer strip, passing through the gap between adjacent strips and covering the outer surface of the adjacent first layer strip. Moisture, such as perspiration will pass via the wicking material through the gaps past the first layer for evaporation and diffusion through a third layer of a liquid impermeable/vapor permeable material which extends over the second layer material covering the outer surfaces of the first layer.
