  • Ballistic modifiers, synthesis . . . propellants
    Patent number: 4243444
    Abstract: A new class of ballistic modifiers and the synthesis thereof is disclosed rein and are used in propellants either individually or as admixtures in percentages of approximately 0.5 to 6 weight percent to impart mesa or plateau burning rate characteristics over a wide pressure range and reduce the temperature sensitivity of the propellants in relation to burning rates. The modifiers are chelate type compounds comprised of lead and/or copper, and various predetermined molar ratios of compounds such as salicylic acid and beta-resorcylic acid.
    Type: Grant
    Filed: September 11, 1970
    Date of Patent: January 6, 1981
    Assignee: The United States of America as represented by the Secretary of the Army
    Inventors: Bernard J. Alley, James D. Dake, Hiram W. H. Dykes

  • Method for preparing small particle size coated ammonium perchlorate
    Patent number: 3953257
    Abstract: A method for preparing aziridine coated ammonium perchlorate (AP) of weight edian diameters (WMD) ranging from about 0.25 to about 5.0 micrometers is disclosed. The method employs either an unlined stainless steel or a polyurethane lined vibro-energy grinding mill wherein a high purity aziridine compound is used as the grinding aid and the coating agent for the AP. The coated AP product extends the pot-life for hydroxyterminated polybutadiene (HTPB) propellant formulations.
