    摘要： Apparatus and method are disclosed for forming rocket motors or the like by mounting a plurality of hollow rocket chambers on a rotary turntable, then filling the chambers under vacuum with a solidifiable rocket propellant slurry. Bores are formed in the slurry in each chamber by inserting core rods therein before the slurry solidifies. After the slurry is cured, the core rods are removed and the chambers are provided with suitable means for completing them into rocket motors.

    摘要： A new method for melt loading explosives is provided by the use of a nozzle with a substantially cylindrical hollow body open at one end and having a restricted orifice at the other end which is provided with a plunger or poppet valve. The plunger has an actuating rod at one end and a plunger head at the other end. The plunger is slidably disposed in the nozzle with the actuating rod extending through the restricted orifice. The plunger head is of complementary shape to the restriction so that when the nozzle is in a normally upright position the plunger head due to hydraulic pressure of molten explosive normally seats against the nozzle restriction to prevent liquid flow therefrom. The actuating rod extending through the restricted orifice, when moved upward, causes the plunger head to move out of contact with the restriction to permit liquid explosive flow. This apparatus is used to facilitate the melt loading of explosives.

    摘要： A process for rapid drying of solvent-wet double-base smokeless powder is provided in which most of the solvent entrapped in the double-base powder particles manufactured by the conventional solvent process is extracted from the powder into the aqueous phase of an aqueous slurry of the powder. The solvent-extracted smokeless powder is then dried employing rapid-drying techniques with no substantial loss of energetic plasticizer.

    摘要： STAPLE-CONTAINING PROPELLANT GRAINS ARE PREPARED BY EXTRUDING STRANDS OF ALL OF THE PROPELLANT INGREDIENTS EXCEPT THE PLASTICIZER AROUND A CONTINUOUS METAL WIRE. THE EXTRUDED STRANDS ARE CHOPPED INTO SHORT PELLETS AND THE PELLETS ARE DISPOSED IN A MOLD. LIQUID PLASTICIER IS THEN INTRODUCED, AND THE GRAIN IS CURED. THE THIS PROCESS, DEGRADATION OF METAL STAPLES DURING MIXING AND CUTTING OF PELLETS IS AVOIDED, AND THE STAPLES TAKE THE FORM OF WIRES WHICH EXTEND THE FULL LENGTH OF THE PELLETS. THE BURNING CHARACTERISTICS OF THE GRAIN ARE SUBSTANTIALLY IMPROVED BY THE INCREASED STAPLE LENGTH.

    摘要： STAPLE-CONTAINING PROPELLANT PELLET GRAINS ARE PREPARED BY INTIMATELY MIXING METAL STAPLES WITH A BINDER, PLASTICIZER AND OXIDIZER, FORMING THE MIXTURE INTO SMALL PELLETS WITH LENGTH APROXIMATELY EQUAL TO DIAMETER, MIXING THE STAPLE-CONTAINING PELLETS WITH ADDITIONAL PROPELLANT INGREDIENTS AT A PROPORTION SUCH THAT THE STAPLE-CONTAINING PELLETS COMPRISE 5 TO 70 WEIGHT PERCENT OF THE MIXTURE TO FORM A VISCOUS SLURRY, CASTING THE SLURRY AND CURING THE RESULTING GRAIN. BURNING CHARACTERISTICS AND PERFORMANCE ARE SUBSTANTIALLY IMPROVED OVER GRAINS PREPARED BY PREVIOUS SLURRY CASTING METHODS, BECAUSE THE STAPLES ARE RANDOMLY ORIENTED AND NOT ALIGNED PARALLEL TO THE MOTOR CASE WALL OR MOTOR MANDREL.
