  • Primer-igniter for gun propellants
    Patent number: 4179992
    Abstract: In small caliber ammunition, an explosive train for igniting the main prolant charge within the cartridge, said explosive train comprising a shock-sensitive percussion primer and a shock-resistant booster charge. The booster charge is formed as a single annular pellet coaxially aligned with the primer. The primer generates a jet of flame through the central hole in the booster pellet, thereby igniting the pellet to a self-heated condition sufficient to ignite the main propellant charge.
    Type: Grant
    Filed: April 4, 1978
    Date of Patent: December 25, 1979
    Assignee: The United States of America as represented by the Secretary of the Army
    Inventors: Jawaharlal Ramnarace, William A. Wood
  • Gas generator propellants
    Patent number: 4111728
    Abstract: A smokeless gas generator composition with an oxygenated binder such as a polyester or a polyether allows higher binder content with less solid oxidizer additives such as guanidine nitrate or ammonium nitrate and allows the composition to be cast.
    Type: Grant
    Filed: February 11, 1977
    Date of Patent: September 5, 1978
    Inventor: Jawaharlal Ramnarace
  • Tracer and composition
    Patent number: 4094711
    Abstract: Improved tracer rounds and compositions therefor comprising a rubbery, particulate mixture having magnesium, polytetrafluoroethylene and advantageously other ingredients coated with copolymer of hexafluoropropylene and vinylidenefluoride, optionally containing ingredients such as carbon black, and providing advantages in preparation (e.g., lower consolidation pressures) and use (e.g., more uniform burning after ignition).

    Assignee: Ford Aerospace & Communications Corporation
    Inventor: Jawaharlal Ramnarace
  • In situ dye smoke
    Patent number: H367
    Abstract: A dye smoke which burns efficiently and without flame consisting essentia of a hydroxyl terminated polybutadiene binder, the biuret trimer of hexamethylene diisocyanate curative, a leucoquinizarin dye referred to as 1,4,9,10-tetrahydroxyanthracene, and ammonium iodate oxidizer. The leucoquinizarin dye is oxidized and iodinated resulting in the iodoanthraquinone derivatives which produce the colored smoke.
