The present invention provides a diffuser cup adapted to fit a primer recess in an ammunition cartridge comprising: a diffuser ring sized to fit in a primer recess for an ammunition cartridge comprising a diffuser top surface opposite a diffuser bottom surface, a diffuser aperture positioned through the diffuser top surface and the diffuser bottom surface such that the diffuser aperture can align with a flash hole, a diffuser neck positioned about the diffuser aperture to extend away from the diffuser top surface, wherein the diffuser neck is sized to fit at least partially through the flash hole; a ring connected to the diffuser neck, wherein the ring comprises a ring aperture connected to the diffuser neck to align the ring aperture and the diffuser aperture; and a cup wall attached to the diffuser ring to extend away from the diffuser bottom surface, wherein the cup wall is configured to frictionally fit a primer and frictionally fit a primer recess.
Abstract:
The present invention provides a subsonic ammunition cartridge including a polymeric casing body comprising a generally cylindrical hollow polymer body having a body base at a first end thereof and a mouth at a second end to define a propellant chamber; a propellant insert positioned in the propellant chamber to reduce the internal volume of the propellant chamber, wherein the propellant chamber has an internal volume that is between 25 and 80% less than the open internal volume of a standard casing of equivalent caliber; and a primer insert positioned at the body base and in communication with the propellant chamber.
Abstract:
An insert for a high strength polymer-based cartridge casing can include an outside, an inside formed within the insert, and a back end disposed at a rear of the cartridge casing. The back end includes a rim and groove disposed around the outside of the insert and a primer pocket disposed inside the back end. Also included is a front end, opposite the back end, having an overmolded area disposed around the outside of the insert above the primer pocket and a basin, having a depth, formed inside the overmolded area. A flash hole can be included inside the insert and communicating between the primer pocket and the basin. The flash hole has a perimeter and a ring disposed around the perimeter of the flash hole, including a height starting at a bottom of the basin, disposed toward the front end, and less than the depth of the basin.
Abstract:
The present invention provides an ammunition disabler with a material capable of being selectively changed in response to an energy wave for preemptively disabling ammunition. In at least one embodiment, the ammunition disabler includes a material selectively structurally changeable from an operative state to a deactivated state upon exposure to an energy wave is provided, where the material is positioned at least partially between the firing pin and the priming compound when the ammunition is chambered within the firearm (with the priming compound positioned between the material and the propellant), and related systems, methods and uses. The material may be contained within the primer cup with the priming compound. The material may be positioned adjacent to the priming compound in direct or indirect contact or in close proximity. The material may be positioned externally from the primer cup.
Abstract:
A vented pyrotechnic device is provided that hermetically seals the pyrotechnic material contained therein under ambient storage conditions, but vents upon exposure to elevated-temperature conditions at or below the outgassing temperature for the pyrotechnic material. The vent passage communicating the chamber containing the pyrotechnic material with the exterior of the device is initially sealed at ambient storage conditions by a temperature-sensitive material. When exposed to a predetermined temperature condition, the temperature-sensitive material undergoes a physical change unblocking the passage and permitting venting of off gases produced by the pyrotechnic material.

Abstract:
The firearm cartridge has an upper chamber adapted to house gunpowder and a bullet, a lower pocket adapted to house a primer, and a flash hole extending there between. The lower pocket has a ledge disposed generally perpendicularly to the flash hole. The flash hole is formed with a perimeter wall that has a convex curvature adjacent to the ledge of the primer pocket. Likewise, a percussion nipple adapted for use in a black powder rifle has an elongated bore formed with relatively larger and smaller diameter portions connected by a shoulder, and the shoulder has a convex curvature adjacent to the larger diameter portion of the bore. The tool for forming the foregoing shapes has a tip provided with a concave curved surface corresponding to the convex curvature of the flash hole perimeter wall on the cartridge or to the convex curvature of the shoulder in the elongated bore of the percussion nipple.
Abstract:
Machine for forming containers (3a), comprising a unit (2) for extruding tubes (3) made of plastic, associated with an electric extrusion motor (200), a blowing unit (5) associated with an electric blowing motor (500), a mould (4) for containing the containers (3a), formed by two half-moulds (4a,4b) movable, upon operation of an associated electric mould motor (400), in a longitudinal direction X-X, the unit formed by the mould (4) and by the associated mould operating motor (400) being displaceable, upon operation of an electric displacement motor (300), in a transverse direction (Y-Y) from a first position substantially aligned with the extrusion unit (2) into a second position substantially aligned with the blowing unit (5) and vice versa, comprising at least one base power supply/recovery module (2000) and at least one first control module (2300) connected to said displacement motor (400) for controlling the acceleration/deceleration thereof.
