  • Patent number: 5646365
    Abstract: The present invention relates to an identifiable bullet and method for identifying such bullets. The bullet comprises a bullet jacket, a lead core and an identification tag in the lead core. In one embodiment, the identification tag is an identification section including a core and an outer protective coating. The core and outer coating are heat-resistant and flexible to prevent damage when the bullet is discharged from a firearm. The identification segment is, in one embodiment, mounted within a chamber formed at the rear end of a main projectile portion, after which a plug or end cap is positioned to hold the identification section in place and protect the identification section from damage. The chamber may comprise one or more annular grooves in which the identification section and/or the end cap extends and engages to securely hold the respective components in place.

  • Patent number: 4339050
    Abstract: A composite or metal baffel system around a fuel tank collapses after punre from an explosive round. The collapse is caused by the overpressure that follows penetration. The collapse delays fuel leakage until the incendiary effect of the explosive round is passed. The delay of fuel leakage is caused by the time it takes for fuel to follow a serpentine path through the collapsed baffel system.
