Method of manufacturing propellants

Claim 1

THE METHOD OF PREPARING A DOUBLE BASE PROPELLANT GRAIN WHICH COMPRISES THE STEPS OF COLLOIDING THE COMPONENTS OF A NITROCELLULOSE-NITROGLYCERINE BASE POWER COMPOSITION TO FORM A COLLOIDAL MIXTURE BY DISSOLVING SAID COMPOSITION IN A SOLUTION OF ACETONE AND WATER, THE INITIAL WEIGHT RATIO OF SAID SOLUTION BEING APPROXIMATELY 0.95 WEIGHT FRACTION OF ACETONE AND 0.05 WEIGHT FRACTION OF WATER, INCORPORATING INTO THE RESULTING COLLOIDAL MIXTURE BY AGITATION AN ADDITIONAL WEIGHT FRACTION OF WATER AS A DECOLLOIDING AGENT IN AN AMOUNT SUFFICIENT TO CAUSE LESS THAN COMPLETE DECOLLOIDING OF THE MIXTURE, SPREADING THE RESULTING PARTIALLY DECOLLOIDED MIXTURE INTO THE FORM OF A THIN FILM, DRYING SAID FILM, REDUCING SAID FILM TO FLAKE FORM, AND FINALLY EXTRUDING SAIUD FLAKES THROUGH AN EXTRUDING DIE IN THE FORM OF A FINISHED PROPELLANT GRAIN.
