  • Patent number: 8608880
    Abstract: A method for the retraction of an explosive component from a high explosive, including the steps of loading a high explosive containing an explosive component into an striping down vessel; supplying a supercritical fluid to the striping down vessel; contacting the high explosive with the supercritical fluid at a temperature below the melting point of the explosive component and at a pressure sufficient to strip down the explosive component; and inducing a sonicating process on the striping down vessel simultaneously at a frequency of 2 MHz to 10 MHz.

  • Patent number: 6265573
    Abstract: A process for separating a nitramine or nitramine intermediate from water and volatile organic compounds comprises the steps of: (a) feeding a liquid stream comprising a liquid nitramine or nitramine intermediate, water, and at least one volatile organic compound, into the upper half of a stripper column; (b) feeding a gas stream having a temperature of at least about 120° C. into the lower half of the stripper column, whereby the gas stream and the liquid stream come into countercurrent contact in the stripper column; (c) withdrawing a nitramine or nitramine intermediate stream from the bottom of the stripper column; and (d) withdrawing a waste stream comprising gas and one or more of water vapor, water, formaldehyde, and acetic acid, from the top of the column.

  • Patent number: H925
    Abstract: An encapsulated signal illuminant flare composition is comprised of powde magnesium from about 45 to about 60 weight percent, of powdered sodium nitrate from about 32 to about 49 weight percent, and of capsular adhesives containing about 91 weight liquid materials contained within capsules having cell walls of equal parts Arabic gum and gelatin of about 9 weight percent to yield a binder from about 6 to about 12 weight percent. The composition ingredients are blended in a dry mixer to achieve a homogeneously, blended signal illuminant flare composition. The blended signal illuminant flare composition is incrementally fed into a flare press for compacting into cartridges in two increments at about 14,000 psi pressure which ruptures the capsular adhesives by hydraulic forces to achieve polymer mixing and the surrounding of the powder ingredients with the binder ingredients to form a very homogenous signal illuminant flare composition mass.
