  • Densifying and stabilizing ingredient
    Patent number: 5192379
    Abstract: Lead fluoride acts as a densifying and stabilizing ingredient for a propent.
    Type: Grant
    Filed: November 6, 1974
    Date of Patent: March 9, 1993
    Assignee: The United States of America as represented by the Secretary of the Navy
    Inventors: Craig E. Johnson, Paul F. Dendor
  • Double-base nitrocellulose propellant
    Patent number: 4126497
    Abstract: A double base propellant having plasticizer and ballistic modifiers unifoy dispersed therein is formed by using high speed, high shear techniques. The method of uniformly incorporating plasticizers and ballistic modifiers in a solventless process for preparing nitrocellulose is accomplished by forming a slurry of nitrocellulose under high shear, high speed mixing, adding the plasticizers and modifiers thereto and recovering the propellant.
    Type: Grant
    Filed: December 13, 1973
    Date of Patent: November 21, 1978
    Assignee: The United States of America as represented by the Secretary of the Navy
