  • Patent number: 6071050
    Abstract: A fine feed adjustment adapter for new milling machinery or retrofitted to existing milling machines is used in order to obtain adjustments of between 1/4 and 1/10,000th of an inch along the z-axis. The fine feed adjustment mechanism does not interfere with the preexisting coarse, vertical adjustment arm which is standard on commercial milling machines.

    Assignee: Mike Patrick
    Inventors: Michael A. Patrick, Richard M. Cook
  • Patent number: 5145535
    Abstract: A method for improving the disperion of particulate materials in intermollar explosive compositions which comprises dry blending at least one fuel compound and at least one oxidizer compound, a viscosity modifier and a dispersable particulate material, melt blending the resulting dry blend, and thereafter casting the melt into a suitable form, casing or mold. The viscosity modifier suitable for use in the invention is a cationic salt of carboxymethylcellulose ether. The viscosity modifier is added in an amount sufficient to achieve a desired melt viscosity.

  • Patent number: 4948438
    Abstract: A melt/cast explosive composition comprising about 20 to 100 wt. % of a binary complex of ammonium nitrate (AN) and methyl nitroguanidine (MeNQ) in a molar ratio of about 0.55:1 to 1.35:1. This binary complex may be used alone or it may be formulated with up to about 80 wt. % compatible fuels and/or oxidizers to tailor the formulation for specific military or commercial applications.
