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.

High pressure washout of chemical agents

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.

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.

Apparatus and method for burning energetic material

Described is a method to recycle laden fluid containing explosives or neutralized chemical agents. For example, the explosive laden fluid is passed through four filtering stages; a clarifier, a filter press, a sand filter and, ultimately, a reverse osmosis device. The feed water to the reverse osmosis device is a saturated solution of explosive or neutralizing chemical agent. The resulting permeate is about 10 ppm of explosive or neutralizing chemical agent.

Process for recycling laden fluids

A process for photolytic degradation of the organic and nitrogenous components of high explosives in organic solvent is described. The process can be applied with a module photolytic apparatus so that munitions can be destroyed without endangering the environment or toxifying large quantities of water. An apparatus is also disclosed.

Device and method for regulating fluid flow within the human body includes small electromagnetic devices embedded in an inner housing of the present device that function under the control of a programmable control unit to create small magnetic fields which cause an artificial increase in the viscosity and apparent density of a magnetorheological fluid located in a compartment surrounding the structure through which fluid flow is to be controlled.

Controller valve device and method

The invention is an abrasive fluid cutting composition comprising a carrier fluid, and an abrasive. Preferably, the composition may also include a surface active agent. The invention also comprises a method for removing material from a substrate through application of the abrasive fluid of the invention comprising the steps of projecting the fluid composition onto the substrate. Reactive materials such as explosives, propellants, flammables, combustibles and the like may be cut using the composition of the invention.

Abrasive fluid jet cutting compositon and method

A self-contained, implantable device for controlling passage of material through internal body conduits, and in particular to control the material passage through a closure point commonly referred to as a sphincter, such as flow through the urethra from the bladder, movement through the bowel, or flow of medications from an artificial conduit that is implanted. The magnetic occluding device comprises a fixed magnetic pressure plate assembly, positioned on one side of a conduit, and a permanent magnet on an opposite side of the conduit. The permanent magnet can be moved so that the magnetic force between the pressure plate and the magnet can be altered from a position wherein the attraction between the movable magnet and the pressure plate carries the conduit between the magnet and the pressure plate to collapse to close off flow through the conduit, to a position wherein the conduit can open. The position of the magnetic poles of the movable magnet is changed either by being rotated or displacing it laterally with the pressure plate so the magnets tend to at least slightly repel each other when the conduit is to be opened. Control of the magnetic force is achieved to insure that the flow of blood in the conduit is not cut off.
