  • Patent number: 10989509
    Abstract: Primer adapter assemblies have a body having a cylindrical exterior sidewall adapted to be closely received in a chamber having a chamber diameter, the body defining a central passage including a cylindrical aft portion adapted to closely receive a primer having a primer diameter greater than or equal to the chamber diameter, the body having an aft surface, and a malleable skirt extending aft of the aft surface and defining an installation aperture, the malleable skirt being operable to deform inward to form an opening having a diameter less than the primer diameter, such that a primer in the cylindrical aft portion of the central passage is retained. The skirt may have a tapered cross-section. The skirt may encircle the central passage. The skirt may be concentric with the central passage. The body may include a flange defining the aft surface and having a diameter greater than the chamber diameter.
    Type: Grant

  • Patent number: 8813652
    Abstract: A projectile includes an ogive at a forward end and a projectile body removably coupled to an aft end of the ogive. A signal dye or a filler material is located within a first cavity in the projectile, wherein the first cavity is at least partially located within the ogive. A pyrophoric material is also located within the first cavity, wherein the pyrophoric material is hermetically sealed either within or by the first cavity.

  • Patent number: 8052091
    Abstract: A cargo parachute release apparatus comprising an assembly plate and a hinged member that is hinged to the assembly plate with a hinge pin. Parachute riser attachment components are positioned between the assembly plate and hinged member when the hinged member is in the closed position. An electronic package assembly having a microprocessor having predetermined parameters is provided, and the electronic package assembly has horizontal and vertical accelerometers and a strain gage for collecting data and sending the data to the microprocessor for processing. When the incoming data matches the predetermined parameters that indicate impact has been made, the microprocessor sends a firing signal to an electro-explosive device to detonate which causes the hinged member to open and release the parachute. The cargo is not dragged along the ground, tipped over or otherwise damaged.
