  • High pressure washout of chemical agents
    Patent number: 5781868
    Abstract: Described is a method of removing chemical agents from the interior of chemical agent filled bodies such as munitions shells. A rotating nozzle is inserted into an opening cut into the shell. High pressure fluidjets (i.e. from about 1,500 psi to above 40,000 psi) are projected from orifices in the nozzle onto the chemical agent in the shell. Chemical agent and chemical agent laden fluid is contained and carried away from the shell for recycle or disposal.
    Type: Grant
    Filed: October 10, 1996
    Date of Patent: July 14, 1998
    Assignee: Alliant Techsystems Inc.
    Inventors: Paul L. Miller, Heather L. Getty, Millard M. Garrison
  • Plasma energy recycle and conversion (PERC) reactor and process
    Patent number: 5762009
    Abstract: Plasma energy recycle and conversion (PERC) reactor and process for disposal of energetics such as solid rocket propellants, liquid rocket fuel, chemical agents such as nerve gas, industrial waste such as paint sludge, medical waste or any aqueous/organic liquid or slurry that is pumpable and for separation/consolidation/conversion of low-level radioactive waste or mixed waste incorporating an induction coupled plasma heat source, insulated primary and secondary reaction chambers and associated peripheral control, process and filter devices.

  • High pressure washout of explosives agents
    Patent number: 5737709
    Abstract: Described is a method of removing explosive agents from the interior of explosive agent filled bodies such as munitions shells. A rotating nozzle is inserted into an opening cut into the shell. Ultra-high pressure fluidjets (i.e. above 40,000 psi) are projected from orifices in the nozzle onto the explosive agent in the shell. Explosive agent and explosive agent laden fluid is contained and carried away from the shell for recycle or disposal.
    Type: Grant

  • Apparatus and method for burning energetic material
    Patent number: 5593301
    Abstract: An apparatus and method for burning combustible material are provided. The apparatus has a combustion chamber with an intake and an exhaust end, a means for injecting combustible material into the intake end of the chamber, a means for igniting the combustible material to generate a flame front, and a means for providing a variance in pressure in the chamber between the intake end and the ignition means, so that a flame front is held substantially stationary in the chamber adjacent the pressure variance means. In its most preferred mode, the apparatus and method may be used for burning energetic materials which, due to their highly volatile and reactive properties, present unique hazards above and beyond those encountered with less reactive non-energetic combustible materials.
