Milca Fils-Aime has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Methods of preparing nitrocellulose based propellants and propellants made therefrom
    Patent number: 10801819
    Abstract: Methods of preparing propellant compositions for power loads and firearms that include providing pre-shaped particle sized starting material, shaped consistent with a desired final propellant product shape, and thereafter nitrating and stabilizing the pre-shaped starting material using boiling stabilization processes. The resulting nitrated propellants of the methods reliably exhibit complete stabilization, high nitrogen substitution, high shelf life and acceptable ballistic performance.
    Type: Grant
    Filed: September 4, 2018
    Date of Patent: October 13, 2020
    Assignee: Northrop Grumman Innovation Systems, Inc.
    Inventors: William J. Worrell, Benjamin R. Vaughan, Jeffrey D. Archambault, Milca Fils-Aime
