Abstract: A double-action bayonet platform is an apparatus used to position a rapidly deployable and stowable backup weapon onto a firearm, constituting an improvement upon existing static bayonets. The double-action bayonet platform utilizes a carrier body, a blade member, a blade actuating mechanism, and at least one weapon attachment mechanism to mount an automatically extendable and retractable blade to the fore-end of a rifle as a modular attachment to any weapon accessory rail systems. The at least one weapon attachment mechanism is externally connected to the carrier body to enable the user to attach the carrier body to a weapon. The blade member is slidably mounted into the carrier body and is operably engaged to the blade actuating mechanism. The blade actuating mechanism is configured to bistably traverse between an extended position and a retracted position, enabling a used to rapidly deploy or stow the blade member as needed.

Abstract: A bayonet mounting fixture can adapt a rifle having a mounting rail to also have a bayonet mount. Previously, bayonets were often mounted to a firearm by passing the barrel through a hole in the guard and then attaching the rear end of the bayonet to a bayonet mount or mounting lug further back. The bayonet mounting fixture can have a forward mount and a rear mount attached to the mounting rail. The forward mount has a round piece that can go inside the hole in the bayonet's guard. The rear mount can have a mounting lug to which the rear end of the bayonet is attached.

Abstract: The invention is a method of measuring oxygen concentration in a package having an oxygen sensitive product disposed therein. The method includes exposing a luminescent compound that is disposed in an interior of the package to light having a wavelength that is absorbed by the luminescent compound so that the luminescent compound is promoted into an excited state. When the exposure of the light is terminated, the excited luminescent compound emits light that is detectable by a detector positioned outside of the package. The intensity of the emitted light is inversely proportional to the oxygen concentration and is used in conjunction with mathematical function that describes the luminescent intensity of the luminescent compound as a function of oxygen concentration and temperature to calculate the oxygen concentration. The method may be used to verify and track the oxygen concentration of a package as it moves through a distribution system.

Abstract: A novel firearm includes an underarm gun stock. The stock of the firearm is to be positioned under the forearm of the firearm user. Alternatively, the firearm has no underarm stock, but the action and barrel of the firearm are disposed beneath the forearm or the wrist of the user. The novel firearms promote a more steady shot with a single hand, the ability to support heavier firepower in a more compact package, and other advantages not found in prior art handguns or rifles.

Abstract: The present invention provides a textile material comprising a tightly woven paper fabric having a backing applied on only one side. The tight weave allows the backing to be applied as a liquid, whereupon curing cause the liquid to harden. The backing confers additional strength and durability to the paper fabric and allows mass production of paper fabrics by the formation of a continuous sheet that can be cut to desired dimensions and shapes without fraying at the edges. The present invention also provides methods for forming tightly woven fabrics and for applying a backing onto this fabric.

Abstract: A bayonet lug clamp and mount assembly is provided for use with a rifle having a T-shaped bayonet lug with slots formed in a central portion thereof. A housing is configured to slidingly engage the bayonet lug. A lever incorporating an accessory mounting rail is pivotally coupled to the housing for movement towards and away therefrom. A jaw is movably mounted in the housing and has teeth that are aligned with the slots in the bayonet lug when the housing is slid thereon. A piston/cylinder assembly is coupled to the lever and to the jaw. When the lever is pivoted towards the housing with the teeth aligned with the slots in the bayonet lug, the piston/cylinder assembly presses the jaw against the bayonet lug as the teeth engage the slots. The lever can be locked to the housing in order to assure that the clamp does not move when the rifle is fired.

Abstract: A bayonet lug clamp has a housing opened on one end thereof for slidingly engaging the bayonet lug. A plate is mounted in the housing and opposes the bayonet lug as the housing is slid thereon. A screw passes through the housing to threadably engage the plate. Turning of the screw draws the plate against the bayonet lug.

Abstract: A muzzle loading firearm includes a receiver, a flash plate adjacent the rear end of the barrel, a downward extending then forward extending exhaust channel and a nipple across the exhaust passageway from the flash plate. The nipple has an ignition passageway which terminates in an output port which is not coaxially aligned with the rear port of the flash passage of the flash plate to prevent backflash from returning through the nipple. The nipple has a forward face which defines a concave arcuate surface in the exhaust channel for further directing the backflash away from the ignition passageway and into the exhaust channel. An exhaust tube, extending forwardly from the receiver for venting the exhaust gases in a safe direction. The exhaust channel and exhaust tube are formed of a material having a high convection coefficient for quickly cooling the exhaust gases.

Abstract: A bayonet system includes a bayonet and a scabbard in which the bayonet is received for storage. The bayonet is formed with an integral blade-and-tang unit. A plastic handle is molded over the tang, with a portion of the tang protruding from a butt end of the handle. A latch plate is attached to the butt end of the handle assembly by a radial rivet to the protruding portion of the tang. The latch plate includes a pair of retainer arms fixed to the latch plate with pins that can be driven out to effect removal of the release arms. The scabbard has a housing with an integral load assembly at its upper end, integral recessed tie-down loops adjacent to its lower end, and an integral hand guard extending from one side at a position intermediate the upper end and the lower end.

Abstract: An accessory mount particularly well suited to a broad variety of weapons (e.g., Heckler & Koch firearms) comprises a plug portion that fits within the weapon accessory mounting hole and is radially expanded, e.g., by means of an interior mandrel, to provide large area, high friction, robust engagement between the plug and the mounting hole. A second portion for holding an accessory (e.g., a laser sight) is coupled to the plug by an alignment means and a hand operated screw or lock so that the accessory is easily removed and reinstalled in the same position relative to the weapon boresight without need for recalibration.

Abstract: A bayonet and scabbard are capable of being pivotally connected to constitute a wire or metal tape cutting implement having a recess shaped to capture the wire or tape before such cutting begins.
