International Classification:

F42B 12/36

US Classification:

102513, 102502, 102367, 102370

Abstract:

Marking cartridge for conventional firearms that deposits marking media on impact with a target. The marking cartridge generally comprises a marking projectile containing a quantity of marking media beneath a frangible cap portion and having a more durable exterior surface adapted to engage the rifling of the barrel when fired. The marking projectile also may comprise a receptacle for marking media having a curled lip adapted to remove air during assembly and excess marking media to insure a consistent quantity of marking media is contained within the marking projectile. The receptacle defining a marking media cavity radially spaced from exterior bearing portion wall and having a mushroom shape. The marking cartridge also may comprise an extendable casing.

International Classification:

F42B 7/08
F42B 7/04

Abstract:

A shotgun shell has a polymer wad with a forward shot cup portion and a rearward propellant cup, the wad in a casing, shot in the shot cup, propellant in the propellant cup, and a primer in a head of the casing. The propellant cup having a plurality of fins extending rearwardly that open to a deployed position upon firing and the shot cup having a plurality of circumferentially spaced axially aligned linear slit segments that permit air to circulate and permit expansion of the shot cup.

International Classification:

F42B 5/38
F41C 9/08

Abstract:

Muzzleloader systems include a pre-packaged propellant charge with a primer receptacle for providing efficient loading and unloading of the muzzleloader. The muzzleloader accepts in the breech end a propellant containment vessel that abuts against a constriction portion with a reduced diameter portion. The propellant containment vessel having an end portion with a tapered surface that conforms to the constriction portion surface. A projectile is inserted in the muzzle end of the muzzleloader and seats against the constriction portion.

International Classification:

F42B 7/08
F42B 7/04

Abstract:

A shotgun shell has a polymer wad with a forward shot cup portion and a rearward propellant cup, the wad in a casing, shot in the shot cup, propellant in the propellant cup, and a primer. The rearward propellant cup portion having enhanced fin deployment such that the shells are operative with shotguns with no chokes, shotguns with ported chokes, and shotguns with conventional chokes. The forward shot cup portion has axial slits that are sized to preclude shot from passing therethrough while providing sufficient air circulation to provide compaction relief of the shot pack. The enhancement may include gussets on the fins, axially movable disks to engage cam surfaces on the fins and urge them outwardly, and fins that have reduced bending regions compared to prior art wads.

B23P 15/00
E06B 3/663
B21D 39/04

Abstract:

A spacer formation cell usable in configuration of a window assembly, wherein the cell includes a plurality of stages through which a spacer work piece is routed, and the stages include a holding stage, a cutting stage, a bending stage, and a connecting stage. The stages can be arranged in interlinked configuration, enabling spacers to be fabricated in a direct and time-efficient manner. The stages can be interlinked to form a framework, forming an exterior enclosure for the stages of the cell, and enabling at least of the majority of the cell's operations to be readily overseen by an operator from single vantage points around the cell. The configuration of the formation cell enables a wide variety of spacer types and/or sizes to be readily processed, with such processing to be readily alternated.
