A fast utility access device (FUAD) is provided that includes one or more casings, each of the one or more casings collectively defining a bore, and a core of a highly exothermic composition contained in the bore and surrounded by a thermally insulating inner liner, the highly exothermic composition ignitable to create a post-ignition temperature of between 500&#xb0; C. and 4000&#xb0; C. A method is also provided for breaching a target and includes contacting the inventive access device with a breaching target substrate, thermally coupling at least one reaction initiator to the highly exothermic composition, triggering the at least one reaction initiator thereby igniting the highly exothermic composition, and allowing the highly exothermic composition to achieve a post-ignition temperature sufficient to melt the breaching target substrate, forming a hole therethrough.

Fast utility access device and method of use thereof

The present invention is directed to a novel, low-toxicity red smoke generating composition and a method of making the same, comprising at least one red dye, a coolant, an oxidizer, a non-sugar binder, and a non-sulfur particulate fuel that is also a burn-control agent having at least one particle size distribution. Preferably, the red dye comprises an anthracene or anthraquinone-based dye and the fuel comprises a sugar or mixture of sugars.

Low toxicity, environmentally friendly red smoke generating composition and method of making the same

The present invention is directed to a novel, low-toxicity and environmentally-friendly violet smoke generating composition. The composition comprises a mixture of at least one red dye and at least one blue dye, a coolant, an oxidizer, a binder, and a non-sulfur particulate fuel that is also a burn-control agent having two different particle size distributions. Preferably the fuel comprises a mixture of granulated sucrose and sucrose 10&#xd7;.

A non-energetic smoke fill composition including a resin, a curing agent, a metallic filler, and a non-metallic filler, wherein the smoke fill composition is configured to be inserted into any of an artillery shell, a mortar cartridge, a gun cartridge, and in general an ogive of a projectile, and wherein the smoke fill composition is configured to be disseminated by a fuze and a supplemental charge to produce a signal visible in both day or night conditions.

A selectable color smoke grenade for producing different color smokes from a single grenade canister. Each grenade canister includes an upper chamber that holds gas producing material and a fuze, one or more dye chambers with dye containing compartments and bypass chambers, a plug positioned between the one or more dye chambers and the upper chamber, and a mixing chamber to receive smoke from the one or more dye chambers and having holes to release the smoke to the environment. Each dye chamber has one or more compartments containing a different color dye. Holes in the plug are used to selectively channel the gases from the upper chamber into one or more of the dye containing compartments. Color selectivity is achieved by changing the alignment between the holes in the plug and the dye containing compartments by rotating the plug and dye chamber relative to each other about a common axis.

The present invention can be characterized as a trainer kit for a Colorimetric Reconnaissance Explosive Squad Screening ('CRESS') kit, which contains a control compound and a set of simulated explosive compositions ('SEC'). The control compound contains no explosive precursor, while each SEC is a combination of one or more explosive precursors that is to be detected by CRESS, and at least one non-explosive additive that reduces the kinetics of the explosive precursor. The SEC retains the colorimetric characteristics of the explosive precursor, but is stable in heat and non-hazardous.

Simulated explosive composition

A flameless smoke pot and a method of generating smoke using the smoke pot. The smoke pot includes a casing having a side wall with an inlet openings and containing a plurality of perforated tubes containing red phosphorous pellets. A heat generating pyrotechnic composition is disposed at a first end of the casing to generate heat which flows through the perforated tubes containing red phosphorous pellets to produce white phosphoric acid clouds of smoke. The white phosphoric acid clouds of smoke are combined with atmospheric an containing water to generate the white phosphoric acid clouds of aerosol smoke. The white phosphoric acid clouds of aerosol smoke are directed through a perforated flame arrester whereby visible flame is prevented from being created.

This invention relates to a smoke-producing composition containing a dye 1,4,- benzenedicarboxylic acid. The acid is useful for purging slag and solid clinker while lowering the steady state burning temperature of the composition. The coloring agent used by the composition does not degrade. The acid is an efficient coolant for the composition and takes advantage of sublimation reactions to produce the properties enumerated here.
