| 146 | COMPOSITE TUBE FOR GUN BARREL | PCT/US0009268 | 2000-04-07 | WO0102789A2 | 2001-01-11 | SMITH DAVID B |
| A composite tube for a gun barrel consists of: an inner tubular metal liner defining a longitudinal bore axis; a resin matrix material surrounding the liner, the resin matrix material containing a plurality of elongate carbon fibers, the carbon fibers being aligned parallel with the longitudinal bore axis of the liner and under compression along the longitudinal bore axis; a muzzle piece attached to the muzzle end of the barrel; and a breech piece attached to the breech end of the barrel, so that any vibrations transmitted along the longitudinal bore axis of the liner are absorbed by the resin matrix material and so that any vibrations reaching the muzzle piece and breech piece are reflected back into the resin matrix material and thus absorbed. A method of manufacturing the composite tube for a gun barrel consists of the steps of: a) grinding the metal liner down from its original thickness to a greatly reduced thickness; b) applying the resin matrix material in layers about the metal liner by wrapping a carbon fiber mat with embedded resin about the metal liner under extreme pressure, until a suitable thickness of resin matrix material has been applied to the metal liner; c) compressing the wrapped resin matrix material; d) heating the wrapped resin matrix material and enclosed metal liner while maintaining compression on the resin matrix material to cure the resin matrix material; e) lathing and sanding the cured resin matrix material to the proper diameter for a gun barrel; and f) attaching the muzzle piece and breech piece to the gun barrel with the adhesive material. | ||||||

| 148 | Less-Lethal Ballistic Projectile Launcher | US15896052 | 2018-02-13 | US20180224229A1 | 2018-08-09 | Thomas A. Teach, JR.; David C. Sult |
| The light-weight handheld less-lethal ballistic projectile launcher is configured as an “over/under” double barrel handheld device with a “break open” loading action. The launcher includes a barrel section pivotally connected to receiver section. The barrel section pivots between an open load/unload position and a closed firing position. The barrel section includes two metal barrel sleeves that are press fit into axial bores formed in the body of the barrel section. The barrel section also includes an ejector, which locks the barrel section in the closed firing position and partially expels spent rounds from the barrel sleeves when the barrel section is opened. The receiver section houses the launcher's fire control mechanism. The fire control mechanism uses a traditional single action operation and ensures that rounds are alternatively discharged from each barrel and prevents rounds from both barrels from being discharged simultaneously. | ||||||

| The present invention discloses a personal protection device for using multiple less-lethal ammunition options. The device is comprised of a lightweight carbon-composite forearm gauntlet sleeve assembly having a multiplicity of external mounts for shortened vented composite less-lethal ammunition barrels of various calibers or other less-lethal ammunition dispensers. In addition, Picatinny Rail attachment points are provided for mounting external tactical gear. Internally, the gauntlet sleeve assembly contains a pistol grip with an electronic control system for selecting and activating individual less-lethal ammunition dispensers in any desired sequence. The invention thus provides the user with multiple selectable less-lethal ammunition options in a single reconfigurable device requiring only one-handed operation while protecting the operating arm. The device has defense utility for both law enforcement and civilians in riots, violent protests, domestic disturbances, commercial aircraft cabins, cruise ships, malls, warehouses, offices and home defense. | ||||||

| 152 | Light gas gun | US14205064 | 2014-03-11 | US09915496B2 | 2018-03-13 | David Wayne Bergeron |
| An improved light gas gun launches a projectile in a light gas atmosphere as it travels through a frictionless barrel to achieve high muzzle velocities, decreased acoustic signatures, and increased ranges. The light gas atmosphere is introduced by a purge valve prior to firing or by a muzzle valve that holds a positive light gas pressure on the barrel and breech. The muzzle valve also routes the majority of propellant gases through a suppression canister, reducing the light gas gun's acoustic signature. The frictionless barrel uses light gas propellant routed through gas bearings to keep the projectile centered in the barrel and preclude the projectile from contacting the barrel walls, eliminating barrel wear. | ||||||

The breech cap is mounted to the barrel liner breech end portion and contacts the barrel tube breech end. The muzzle cap is mounted to the barrel liner muzzle end portion and contacts the barrel tube muzzle end. The inside diameter of the barrel tube bore is greater than the outside diameter of the barrel liner whereby the barrel tube does not contact the barrel liner. | ||||||
