  • Patent number: 11473888
    Abstract: Spotter ammunition projectiles adapted to be fired from a firearm, methods for making spotter ammunition projectiles, and spotter ammunition cartridges including spotter ammunition projectiles are provided. In one example, a spotter ammunition projectile includes a projectile body section extending in a distal direction to a body distal end portion. A projectile ogive is coupled to the body distal end portion and has an outer ogive surface that tapers in the distal direction towards a shoulder. The projectile ogive includes a post that is disposed adjacent to the shoulder and that extends therefrom in the distal direction. An ogive nose cap is disposed adjacent to the shoulder and covers the post. The post and the ogive nose cap are cooperatively configured to define a cavity therebetween. A pyrotechnic spotter composition is disposed in the cavity.

  • Patent number: 11287235
    Abstract: Nonlethal cartridges adapted to be chambered in a firearm having a barrel that includes rifling are provided. In one example, the cartridge includes a cartridge case and a sabot that is telescopically coupled to the cartridge case and that has a sabot mouth. A projectile includes a polymer base projectile portion disposed in the sabot mouth. A polymer front shell projectile portion is coupled to the polymer base projectile portion and has an outer surface that includes a circular locking rib feature that forms an interference fit with the sabot mouth. The polymer base projectile portion is configured to engage the rifling of the barrel to impart spin stabilization to the nonlethal projectile when propelled from the sabot in response to the expansion of a propellant gas.

  • Patent number: 11221844
    Abstract: An automated application partitioning system is configured to receive a software application, and a specification of two or more entry points of the software application. The automated application partitioning system, by means of a dependence analysis groups application components, such that there is provided for each entry point dependency subset a corresponding feature subset, and at least one shared subset.

  • Patent number: 9157715
    Abstract: A marking projectile configured to be fired through the barrel of a firearm having rifling formed therein is provided. The marking projectile includes a polymeric base portion configured to engage the rifling of the barrel and a polymeric front shell portion coupled to the base portion. The polymeric front shell portion has a cavity formed therein for housing a marking compound and a structure configured to deform on impact and thereby release the marking compound. The marking projectile includes a metallic annular sealing component (e.g., a crimped metal ring) configured to seal the polymeric front shell portion to the polymeric base portion.

  • Patent number: 8327767
    Abstract: The present invention discloses a reduced energy training cartridge for use in a straight blowback operated firearm having a barrel with firing chamber, the cartridge comprising a cartridge case being defined by a rear portion with an external groove, a front portion having a velocity reduction structure and a wall with an outer surface and an inner surface, a sabot slideably engaged within the cartridge case, the sabot having a rear portion with an outside diameter substantially equal to the inside diameter of the inner surface of the cartridge case and which contains a gas sealing and braking structure and a primer disposed in the rear portion of the cartridge case where, upon percussion of the primer, the cartridge case rapidly slides relative to the sabot until such point when the velocity reduction structure of the cartridge case engages with the sealing and braking structure of the sabot, thereby stopping further movement of the cartridge case relative to the sabot, The present invention also contemplat
