  • Patent number: 5212308
    Abstract: The invention provides a continuous moving bed reactor, useful for the prration of 3,7-diacetyl-1,3,5,7-tetraazabicyclo-3.3.1-nonane (DAPT). The reactor makes novel use of water, a known catalyst for said reaction. However, in this invention, the water is present as ice. The ice is made to automatically promote and moderate the reaction as well as regulate the flow of hexamine into the reactor. These automatic functions are achieved by mixing ice with hexamine, the latter is one of two principle reactants used, to generate a standing bed of slurry. When melted at its base, the slurry advanced under the influence of gravity. The melting of the ice being caused by local application of the second principle reactant, acetic anhydride, which is a liquid.The apparatus is constructed in the following way. A tube shaped reservoir for containing the cited slurry is open at the top end and terminates at its bottom end by a porous compartment. The latter compartment openly retains the slurry. A fluid delivery device, i.

  • Patent number: H1011
    Abstract: An anti-aircraft mine which ejects fragment(s) upwardly from an upright ption in a selected ground area. The mine includes a warhead subassembly having walls forming a chamber for an explosive and having a frontplate which forms and ejects fragments upon an explosion, and includes a stabilization subassembly using a fin for controlling the trajectory of descent and its position of landing, after its ejection from an artillery projectile, and includes a target sensing subassembly having an antenna and signal processor and computer for tracking a low flying object, such as a plane, helicopter, drone, or missile, and for upwardly ejecting its fragments when the object enters a lethal zone of the mine.
