  • Patent number: 8444881
    Abstract: The present invention relates to methods for producing non-detonable and non-explosive parent-odor scent simulants of both detonable and entropy-burst chemical explosive materials. A detonable explosive material is a material that explosives with the aid of detonation while an entropy burst explosive material is a very sensitive energetic material that does not require detonation, but explodes through a spontaneous decomposition of its molecules into gaseous products. The invention also presents representative non-detonable, non-hazardous compositions of such simulants that can be safely and effectively utilized within a broad spectrum of biological and non-biological explosives detection programs, non-limiting examples being the training of biological search-and-detect creatures such as explosive detecting dogs and the calibration of electronic explosive detecting instruments that rely on the principles of vapor sampling for their operations.

  • Publication number: 20030009064
    Abstract: A tubular reactor characterized by having short static mixing elements separated by coalescing zones is used to conduct multiphase liquid/liquid reactions. Small droplets of one of the phases are dispersed into the other phase by the static mixing elements. These droplets coalesce and at least partially phase separate as the mixture passes through the subsequent coalescing zone. The tubular reactor is particularly suitable for nitrating organic compounds while forming low levels of improperly nitrated by-products and low levels of nitrophenolics.

    Abstract: An automated propellant blending apparatus and method uses closely metered addition of countersolvent to a binder solution with propellant particles dispersed therein to precisely control binder precipitation and particle aggregation. A profile of binder precipitation versus countersolvent-solvent ratio is established empirically and used in a computer algorithm to establish countersolvent addition parameters near the cloud point for controlling the transition of properties of the binder during agglomeration and finishing of the propellant composition particles. The system is remotely operated by computer for safety, reliability and improved product properties, and also increases product output.

  • Patent number: 5156779
    Abstract: A method and an improved eductor apparatus for producing ultrafine explosive particles is disclosed. The explosive particles, which when incorporated into a binder system, have the ability to propagate in thin sheets, and have very low impact sensitivity and very high propagation sensitivity. A stream of a solution of the explosive dissolved in a solvent is thoroughly mixed with a stream of an inert nonsolvent by obtaining nonlaminar flow of the streams by applying pressure against the flow of the nonsolvent stream, to thereby diverge the stream as it contacts the explosive solution, and violently agitating the combined stream to rapidly precipitate the explosive particles from the solution in the form of generally spheroidal, ultrafine particles. The two streams are injected coaxially through continuous, concentric orifices of a nozzle into a mixing chamber. Preferably, the nonsolvent stream is injected centrally of the explosive solution stream.

  • Patent number: 4931229
    Abstract: A method and apparatus for protecting a mixing apparatus for producing strand-shaped explosives and propellants in a twin-shaft screw extruder, the housing of which is formed of housing parts connected to a clamping device acting under hydraulic pressure. In order to compensate for excessive pressure and to prevent abrupt opening of the mixing chamber, the torque developed at the screw shafts is continuously monitered and fed to a control and storage device together with temperature and pressure values measured at the end of the screw shaft in the material being processed. If one of the measure values exceeds a permissable limit, a signal is produced to change the operating condition of the screw extruder, particularly to stop and withdraw the extruder from the housing, to halt the drive motor of the extruder shafts and to open the extruder housing by relieving the clamping device.

    Abstract: A process and apparatus is provided for the continuous manufacture of a water-in-oil explosive emulsion precursor. Separate streams of the water phase component and the oil phase component are introduced into an in-line motionless mixer. A chosen portion of the output from the mixer is recirculated and returned to the motionless mixer for further emulsification. The process allows for the production of a very high phase ratio water-to-oil emulsion (up to 95% water phase) without phase inversion after long storage. The precursor is simply converted to a sensitive explosive by means of known density lowering techniques.

    Abstract: The continuous production of an explosive is achieved by intermixing at least two liquid component streams in an apparatus including a mixing rotor generally formed like a turbine impeller and freely rotatably supported in a housing directly opposite an inlet opening for one of the liquid components. The passing liquid stream imparts a rotational motion to the mixing rotor and the liquid components are effectively mixed by shear and turbulence in an annular narrow mixing zone between the outer periphery of the rotor and the inner wall of the housing. Preferably the entire surface of the mixing rotor is surrounded by the flowing liquid components, thus providing a low friction hydrostatic rotor support.
