  • Patent number: 9322625
    Abstract: A water-resistant cartridge includes a pyrotechnic that when ignited launches water from a disrupter cannon to disable and/or destroy an explosive device. The cartridge includes a seal that seals between an outer surface of the cartridge and an inner surface of the barrel to limit water that escapes from the barrel rearward of the seal and cartridge. Prior to launching the water, the water in the barrel surrounds the cartridge forward of the seal. As the pyrotechnic burns and provides an expansive force on the sides of the cartridge, the water between the sides of the cartridge and the inner surface of the barrel resists the expansive force to help retain the shape of the cartridge, so that it may be more easily removed from the barrel after firing. The force provided by the pyrotechnic blows a cover of the cartridge off to provide the force directly to the water to launch the water.

  • Patent number: 8833223
    Abstract: A multi-petal adapter that enables projectiles of different sizes to be used in a single dearmer. The adapter includes a plurality of petals that are secured, in a detachable way, to a base. The main function of the base is to secure the petals until the projectile is fired from the dearmer. Whereupon, the adapter will start petalling until the petals become detached from the base, so that the adapter imparts minimal or no energy or damage to the intended target. The adapter fully regulates the energy imparted to the various projectiles, by allowing propellant gases to bleed through channels that are formed between the petals. As a result, the present adapter fully supports a proper projectile launch and ensures its proper orientation toward the target.

    Abstract: A portable containment chamber for disposing of explosive threat devices comprises a cylindrical chamber body with a hinged interiorly convex outward-opening access door. The door closes against a tapered seat whereby explosion pressure enhances a gas-tight seal. In closed position the door is locked by interconnected expandable locking shoes which engage an annular locking channel in the mouth of the chamber with a simultaneous crank-and-piston linkage. The door is actuated by a pneumatic mechanism which first traverses laterally it into alignment with the chamber, then traverses it axially into sealing engagement with the chamber mouth, and then moves the expandable locking shoes into locked position. A first interlock prevents axial door movement when in standby position, and a second interlock inhibits detonation of a donor explosive charge within the chamber if the door locking shoes are not fully locked.

    Abstract: A blast treatment method and an apparatus, which can perform the blast treatment of a treatment subject by using and securely initiating a blasting explosive having fluidity. The blast treatment method includes: a blasting preparation operation of housing a blasting explosive having fluidity in a container and placing the blasting explosive around a treatment subject as well as attaching an initiation device to the container; a housing operation of housing the container, the blasting explosive, and the treatment subject in a chamber; a decompression operation of decompressing the inside of the chamber; and a blasting operation of initiating the blasting explosive and blasting the treatment subject with the blasting explosive. In the decompression operation, the inside of the chamber is decompressed while a gas vent portion regulates the escape of the blasting explosive to the outside of the container and permits the escape of gases in the container to the outside.

  • Patent number: 8453550
    Abstract: A blast treatment method for blasting a treatment subject having an outer shell and a chemical agent charged into an interior of the outer shell includes the steps of: disposing an explosive to cover a periphery of the treatment subject; and detonating the explosive from respective end portions of a specific direction toward a predetermined cutting position of the treatment subject between the respective end portions so that detonation waves of the explosive advancing from respective sides of the cutting position collide in the cutting position, wherein, in the step of detonating the explosive, the chemical agent is exposed by cutting the outer shell in the cutting position through detonation of the explosive, and the chemical agent is decomposed using the detonation.

  • Patent number: 8430011
    Abstract: A system for disabling or degrading electrically initiated explosive devices includes an apparatus for inducing waveforms of varying power and duration into the leads of a bridgewire based blasting cap, thus raising the resistance to render the blasting cap inoperable without requiring detonation, and for polling or confirming electrical performance and operational status of the blasting cap. An operational methodology for neutralizing an explosive device is included.

  • Publication number: 20120312147
    Abstract: A portable containment chamber for safely disposing of suspected explosive threat devices comprises a cylindrical chamber body and hinged outward-opening access door. The door seals against a tapered seat and extends convexly into the interior of the chamber, whereby blast pressure tends to expand the door into enhanced gas-tight sealing engagement. The mouth of the chamber has an annular locking channel with which the door is locked in closed position by an expandable interconnected locking shoes driven by a crank-and-piston linkage such that all shoes are simultaneously locked and unlocked by movement of a common crank. A two-stage door operating mechanism first moves the unlocked door axially out of sealed position, and then rotates it to one side to provide access to the interior of the chamber. For closing, the sequence of movements is reversed.
