  • Non-lethal tranquilizer bullet
    Patent number: 11236979
    Abstract: A non-lethal tranquilizer bullet is provided. The non-lethal tranquilizer bullet may include a housing defining an internal space and having a non-penetrating distal tip. A plunger assembly, a tranquilizer fluid, and at least one plunger stop may be disposed in the internal space. The plunger assembly can include a piston and a needle, and the needle may include a shaft terminating in a tip. The shaft may have a plurality of holes disposed along its length. When the bullet is fired from a gun and contacts a living body, the plunger assembly can move toward the non-penetrating distal tip such that the needle tip breaches the housing tip and enters the living body. The force of the plunger assembly moving forward may disperse the tranquilizer fluid into the living body through at least one of the plurality of holes. The plunger stop can prevent the piston from exiting the tip.

  • Press load process for warheads
    Patent number: 11209255
    Abstract: An improved process provides high-density pre-form billets that meet dimensional limitations required for case-load tooling. Previous isostatic fill procedures were improved in two ways to accommodate varying bulk densities or powder compositions. First, during the isostatic fill procedure, the powder fill is subject to both a high frequency vibration and a high amplitude, low frequency impulse. The combination of these two inputs is critical to ensure polymer bonded explosives pack to consistent densities. Second, unlike in conventional practices, the fill rate is kept constant throughout the entire fill process and the mold is completely filled by the time the required powder mass has been dispensed.
