Abstract: Novel clothing fabrics containing microcapsules in a resin finish compris reactive chemical decontamination agents encapsulated within a semipermeable polymer which is selectively permeable to toxic chemical agents but impermeable to the decontamination agents, thereby allowing the toxic chemicals to diffuse into the microcapsules where they undergo irreversible detoxifying chemical reactions.

Abstract: A process of making and filling an envelope shaped as a ring airfoil for use as a projectile. The envelope is formed of resilient material into a tubular shape with an outer wall portion and an inner wall portion located along the tubular extent thereof with a foldable portion therebetween. The walls are relatively moved to form a payload cavity by moving the inner wall to nest within the outer wall by folding at the foldable portion with the ends contiguous. The foldable portion forms the leading edge of the airfoil. The trailing edge is formed by joining the contiguous ends. Payload filling and final sealing steps complete the airfoil projectile shape.

Abstract: A process of using a two-phase gas or liquid filter and thin layer chromaraphy member having a filter portion and a chromatography portion. The sample is collected and analyzed on the same member. A developing solvent of substantially acrylonitrile-benzene-petroleum ether is used to allow the sample to chromatograph on the chromatography portion of the member.

Abstract: An improved method for preparing a "plasticized" red phosphorous smoke ag through the steps comprising mixing particulate red phosphorous with a non-swollen, commercial latex polymer "plasticizer." In the preferred embodiment the latex polymer plasticizer is a butyl rubber.

Abstract: The invention relates to a cross-linked composition of matter comprising acrylonitrile, (B) an acrylonitrile-soluble, carboxy group containing acrylic polymer capable of being cross-linked through the carboxy groups and (C) an acrylonitrile-soluble, carboxy group-reactive cross-linking agent.

Abstract: An improved method for identification and qualitative determination of potentially harmful pollutants in water through the use of a novel sampling test tube apparatus which consists essentially of a test tube containing a foam cube which has been impregnated with a detection chemical solution selected to react colorimetrically with specific pollutants to be detected.

Abstract: A method for oxidatively degrading organophosphorous esters to phosphoric id, carbon dioxide and water through the use of a source of free hydroxy radicals, saturation of the resulting solution with oxygen and subsequent irradiation with UV radiation between 220 and 280 nm.

Abstract: A method of preparing anticholinesterase organophosphoro and organophosph-fluoridates, e.g., GB in situ by mixing a phosphorous ester in an aprotic solvent with a solution of tetraethylammonium in the same solvent.

Abstract: A method of direct water hydrolysis of phosgene consisting essentially of e step of intimately contacting phosgene with water through means of a porous material submerged in the water through which gaseous phosgene is passed to produce a commercially useful concentration of hydrochloric acid and gaseous carbon dioxide.

Abstract: A method for rapidly detecting organic pollutants in water utilizing cheml effervescence to accelerate release of contaminants into the atmosphere above the water sample where they can be detected by conventional air pollution detector tubes. An apparatus for detecting contaminants in the atmosphere above the water solution by detector tube is also disclosed.

Abstract: A test agent, generation system capable of producing a low constant vapor test agent for use in a method of calibrating and checking the GB agent sensitivity of a point-source alarm system.

Abstract: A method of challenging an agent alarm for the detection of V and G agents hrough the use of a simulant compound which has no significant toxicity and which will test the three principal components of the alarm, namely the conversion filler, heating element, and the detection cell. The stimulant compound has the general formula ##STR1## wherein R" is a lower alkyl group selected to produce a readily displaced alkylmercapto moiety when reacted with the AgNO.sub.3 and KF of the conversion filter and R is a longer chain alkyl selected to give a volatility similar to that of less volatile G agents.

Abstract: 1. A compound having the structure represented by the formula: ##STR1## in which R is selected from the group consisting of alkyl groups of 1-5 bon atoms and cycloalkyl groups of 6-9 carbon atoms.

Abstract: The invention relates to a unique chemical heater formulation for generat heat through the exothermic reduction of cupric chloride by aluminum. The chemical reaction system used in the heater formulation contains a cupric chloride, a wetting agent, water and a polar organic solvent for said cupric chloride which when contacted with aluminum will react to produce temperatures in excess of 100.degree. C for a sustained period of time, with peak temperature reaching the order of 156.degree. C. Optimum results have been achieved with a reaction system consisting essentially of cupric chloride dihydrate, 48.4wt%; polyethylene glycol 1.6 wt%; water 9.7 wt% and ethylene glycol, 40.3wt%.
