Abstract: The invention provides for a receptor, capable of binding to a target molecule, linked to a hygroscopic polymer or hydrogel; and the use of this receptor in a device for detecting the target molecule in a gaseous and/or liquid phase. The invention also provides for a method for detecting the presence of a target molecule in the gas phase using the device. In particular, the receptor can be a peptide capable of binding a 2,4,6-trinitrotoluene (TNT) or 2,4,-dinitrotoluene (DNT).

Abstract: A solvent-free process is used to make mouldable plastic explosives or mouldable plastic explosive simulant products.

Abstract: Gel and solid rocket propellant is physically and chemically ablated from motors using a liquid or gaseous reagent such as anhydrous ammonia propelled by compressed nitrogen gas at 2000 psig or higher. Nitroglycerine and nitrocellulose are nitrate esters preferentially ablated from class 1.1 rocket propellant by anhydrous ammonia at a temperature of 70.degree. F. or higher.

Abstract: Emulsion explosive sensitive to a detonator, which can be initiated with a conventional detonator no. 8, of water-in-oil-emulsion type containing sensitizers which, as opposed to types known previously, here comprise aromatic nitro-compounds, in which emulsion the organic phase consists primarily of the aromatic nitro-compounds and the water phase consists primarily of a water solution of inorganic oxidizing salts and in which emulsion emulsifier is also included; detonation stabilizers in the form of particles with enclosed or adsorbed gas ("hot spots"); additional fuels such as aluminium, urea, etc.; optional stabilizers for the organic phase and for the water phase; and possibly an agent to lower the crystallization point.

Abstract: Explosive or propellant powder which include a cation exchange polymer having alkali metal ions bound thereto, and method of preparation.

Abstract: The present invention relates to a primer composition formed of TNT, DNT (2,4-dinitrotoluene) and fine particle size PETN (pentaerythritol tetranitrate) for use with explosive charges. This composition is extruded in melt condition into primer cartridges. Any topping-off operations are eliminated since practically no shrinkage occurs as the melt cools to form a solid casting in the cartridge.

Abstract: Composite explosive slurries of good stability and flow properties are obned by dispersing particulate solid components, e.g. RDX, NH.sub.4 NO.sub.3 and Al, in molten TNT in the presence of a small amount of arabinogalactan or gum arabic to inhibit segregation of the suspended solids.

Abstract: The explosives, explosive mixtures or assemblies according to the invention contain at least one new nitrated 2,5,8-triphenyl-tris-triazolobenzene derivative of the general formula (I) ##SPC1##wherein n represents an integer of two or three, or a nitromethane or nitric acid adduct of said compounds, and optionally contain known additives, too.The thermal stabilities of these products are much better than that of the hitherto known brisant explosives, and at the same time their brisance and other explosive characteristics are satisfactory.

Abstract: Propellant inhibitors are provided for cellulose-containing particulate solid propellants, and particularly for nitrocellulose-containing gun propellants, in which the inhibitor is the reaction product of a polyfunctional isocyanate such as polymethylene polyphenyl isocyanate and a polyol such as polyethylene glycol.
