Propellant mixing process

Claim 1

A METHOD FOR PREPARING A SOLID COMPOSITE TYPE PROPELLANT WHEREIN FINELY DIVIDED SOLID INGREDIENTS COMPRISING AN OXIDIZER COMPONENT SELECTED FROM THE GROUP CONSISTING OF SOLID INORGANIC OXIDIZING SALTS, MIXTURES OF SAID INORGANIC SALTS, AND MIXTURES OF A SOLID INORGANIC OXIDIZING SALT WITH A SOLID ORGANIC OXIDIZING COMPOUND SELECTED FROM THE GROUP CONSISTING OF CYCLOTRIMETHYLENE TRINITRAMINE, PENTAERYTHRITOL TETRANITRATE, CYANOGRANIDINE. NITROGUANIDINE, AND GUANIDINE NITRATE WHEREIN THE MIXTURE CONTAINS UP TO 10 PARTS BY WEIGHT OF SAID ORGANIC COMPOUND PER 100 PARTS BY WEIGHT OF SAID ORGANIC SALT, ARE UNIFORMLY DISPERSED IN A BINDER COMPONENT COMPRISING A RUBBERY POLYMER SELECTED FROM THE GROUP CONSISTING OF NATURAL RUBBER, SYNTHETIC RUBBER POLYMERS, AND MIXTURES THEREOF, WHICH METHOD COMPRISES, IN COMBINATION, THE STEPS OF; MECHANICALLY MIXING SAID SOLID INGREDIENTS INTO SAID BINDER COMPONENT UNTIL A POWDERY MASS IS OBTAINED THEN INCORPORATING A LOW BOILING ORGANIC SOLVENT SELECTED FROM THE GROUP CONSISTING OF HEXANE, HEPTANE, OCTANE, NONANE, CYCLOHEPTANE, CYCLOHEXANE, BENZENE, TOLUENC, XYLENE, METHYLCYCLOHEXANE, NAPHTHAL FRACTIONS, KEROSENE FRACTIONS, CARBON TETRACHLORIDE 1,2-DICHLOROETHYLENE, AND 1,2-DICHLOROETHANE, IN AN AMOUNT SUFFICIENT TO SOFTEN SAID BINDER COMPONENT, INTO SAID POWDERY MASS WITH SUFFICIENT MECHANICAL MIXING TO FORM A UNIFORM INTERMEDIATE DISPERSION OF SAID SOLID INGREDIENTS IN SAID BINDER COMPONENT; THEN MECHANICALLY MIXING AT LEAST ONE ADDITIONAL INCREMENT OF SAID SOLID INGREDIENTS INTO SAID INTERMEDIATE DISPERSION WITH SUFFICIENT MIXING TO ATTAIN A FINAL UNIFORM DISPERSION OF SAID SOLID INGREDIENTS IN SAID BINDER COMPONENT; AND THEN EVAPORATING SAID SOLVENT FROM SAID FINAL DISPERSION.

Claim 2

A METHOD FOR PREPARING A SOLID COMPOSITE TYPE PROPELLANT WHEREIN FINELY DIVIDED SOLID INGREDIENTS COMPRISING AN OXIDIZER COMPONENT SELECTED FROM THE GROUP CONSISTING OF SOLID INORGANIC OXIDIZING SALTS, MIXTURES OF SAID INORGANIC SALTS, AND MIXTURES OF A SOLID INORGANIC OXIDIZING SALT WITH A SOLID ORGANIC OXIDIZING COMPOUND SELECTED FROM THE GROUP CONSISTING OF CYCLOTRIMETHYLENE TRINITRAMINE, PENTAERYTHRITOL TETRANITRATE, CYANOGRANIDINE. NITROGUANIDINE, AND GUANIDINE NITRATE WHEREIN THE MIXTURE CONTAINS UP TO 10 PARTS BY WEIGHT OF SAID ORGANIC COMPOUND PER 100 PARTS BY WEIGHT OF SAID ORGANIC SALT, ARE UNIFORMLY DISPERSED IN A BINDER COMPONENT COMPRISING A RUBBERY POLYMER SELECTED FROM THE GROUP CONSISTING OF NATURAL RUBBER, SYNTHETIC RUBBER POLYMERS, AND MIXTURES THEREOF, WHICH METHOD COMPRISES, IN COMBINATION, THE STEPS OF; MECHANICALLY MIXING SAID SOLID INGREDIENTS INTO SAID BINDER COMPONENT UNTIL A POWDERY MASS IS OBTAINED THEN INCORPORATING A LOW BOILING ORGANIC SOLVENT SELECTED FROM THE GROUP CONSISTING OF HEXANE, HEPTANE, OCTANE, NONANE, CYCLOHEPTANE, CYCLOHEXANE, BENZENE, TOLUENC, XYLENE, METHYLCYCLOHEXANE, NAPHTHAL FRACTIONS, KEROSENE FRACTIONS, CARBON TETRACHLORIDE 1,2-DICHLOROETHYLENE, AND 1,2-DICHLOROETHANE, IN AN AMOUNT SUFFICIENT TO SOFTEN SAID BINDER COMPONENT, INTO SAID POWDERY MASS WITH SUFFICIENT MECHANICAL MIXING TO FORM A UNIFORM INTERMEDIATE DISPERSION OF SAID SOLID INGREDIENTS IN SAID BINDER COMPONENT; THEN MECHANICALLY MIXING AT LEAST ONE ADDITIONAL INCREMENT OF SAID SOLID INGREDIENTS INTO SAID INTERMEDIATE DISPERSION WITH SUFFICIENT MIXING TO ATTAIN A FINAL UNIFORM DISPERSION OF SAID SOLID INGREDIENTS IN SAID BINDER COMPONENT; AND THEN EVAPORATING SAID SOLVENT FROM SAID FINAL DISPERSION.
