Method for destroying energetic materials

InactiveUS6121506AAffect environmentSafely, simply and economicallyAmmunitionHalogenated hydrocarbon separation/purificationChemical reactionSolvation
Energetic materials, such as nitrocellulose, TNT, RDX, and combinations thereof, optionally in combination with chemical warfare agents, such as mustard gas, Lewisite, Tabun, Sarin, Toman, VX, and combinations thereof, are destroyed when chemically reacted according to the method of the invention. The method comprises reacting the energetic materials and chemical warfare agents, of present, with solvated electrons which are preferably produced by dissolving an active metal such as sodium in a nitrogenous base such as anhydrous liquid ammonia.

Flame suppressant aerosol generant

The present invention is directed to pyrotechnic aerosol fire suppression compositions that burn rapidly, but coolly. The rapid burning of the compositions of the present invention produces a voluminous flame-suppressive aerosol that is useful in suppressing and / or extinguishing both small and large fires. The compositions of the invention contain at least one oxidizer and a fuel component comprising at least one organic acid salt, which combination produces a rapid burning composition that burns at low temperatures with little or no flame.

A gas generant is provided which decreases toxic components, in particular carbon monoxide and nitrogen oxides, in generated gas to a concentration practical as an air bag system for automobile.A nitrogen-containing organic compound such as a compound containing amino group or amido group or a tetrazole derivative and a oxygen-containing inorganic oxidizer such as KNO3, Sr(NO3)2 or KClO4 are essential components. Therewith one or more metal oxides are contained in the mixed catalyst of the gas generant composition. The oxide is selected from manganese dioxide having a specific surface area not less than 50 m2 / g; copper oxide having a specific surface area not less than 1 m2 / g; molybdenum oxides such as molybdenum dioxide, molybdenum trioxide, molybdic acid and ammonium molybdate: and copper oxides, cobalt oxides, iron oxides and silver oxides.

Method of marking a product, marked product resulting thereof, and method of identifying same

A method and means for identifying the authenticity and the genuine nature of a solid or liquid bulk material, by incorporating a marking composition containing at least one trace ion into the said bulk material, whereby the total concentration of the incorporated trace ions in the market bulk material is chosen to be lower than the corresponding concentration of the same ions in standard sea water. The authenticity and the genuine nature or the adulteration level of the marked bulk material can be tested in-the-field using electrochemical sensors, and confirmed in the laboratory using a method such as atomic absorption spectroscopy, ion chromatography or mass spectrometry.

Castable infrared illuminant compositions

Compositions are provided which, when burned, produce significant levels of infrared radiation, but only limited levels of visible radiation. The basic components of the compositions include a binder, an oxidizer, and a fuel, where the binder also acts the fuel. Preferred oxidizers include those compounds which produce large quantities of infrared radiation when the flare composition is burned. Such oxidizers include potassium nitrate, cesium nitrate, rubidium nitrate, and combinations of these compounds. Selection of the binder is important in order to provide the composition with the desirable characteristics identified above. The binder of the present invention does not produce significant soot. At the same time, the binder serves to form a composition which is processible, avoids chunking, and is compatible with the oxidizers used. It has been found that polymer binders which include relatively short carbon chains (1-6 continuous carbon atoms) are preferred. Examples of such polymers include polyesters, polyethers, polyamides, and polyamines.

Method for bioremediating undetonated explosive device

Technology for in situ remediation of undetonated explosive device. An explosive device contains an explosive material in close proximity with microorganisms capable of metabolizing the explosive material that are either mobile or temporarily deactivated by freeze drying. Examples include Pseudomonas spp., Escherichia spp., Morganella spp., Rhodococcus spp., Comamonas spp., and denitrifying microorganisms. A self-remediating explosive mixture includes an explosive material intermixed with microorganisms. Joined with an explosive device is a bioremediation apparatus that contains microorganisms and prevents contact between microorganisms and explosive material in the explosive device using a barrier that is actuated to release the microorganisms by mechanical, electrical, or chemical mechanisms. If the explosive device fails to detonate, remediation by microorganisms includes both disabling of the explosive material and detoxification of resulting chemical compositions.
