81 SHROUD FOR A FIREARM AND A METHOD OF CONFIGURING THE SAME US13011276 2011-01-21 US20120117847A1 2012-05-17 Andrew James Evans-Hendrick
A shroud is provided (10) for a firearm (50) having a longitudinal barrel (52). The shroud is configured to co-operate with formations (54) provided on the firearm barrel such as to provide axial alignment therebetween. The shroud further comprises means (11) for mounting one or more devices to the shroud. The alignment between the barrel and the shroud provides for alignment between the device(s) and the barrel. A firearm comprising such a shroud, and a method of configuring a firearm comprising the shroud are also provided.
82 Retrofit cooling system for gatling machine gun US11825025 2007-07-03 US07793577B2 2010-09-14 Tracy W. Garwood
A cooling system for a Gatling machine gun can be use to retrofit an existing machine gun or can be incorporated in a newly manufactured gun. The system directs fluid through the housing assembly of the machine gun to a location intermediate barrels of the gun, and discharges the fluid to cool the barrels.
83 Finned carbine handguard assembly US10758159 2004-01-15 US06945154B1 2005-09-20 Randy E. Luth
A gun barrel handguard includes half sections having longitudinally spaced apart fins of plastic material positioned around the exterior of the gun barrel for absorbing heat but preventing it from being quickly transmitted to the exterior of the handguard.
84 MULTI-PIECE GUN BARREL SHROUD SYSTEM US10327391 2002-12-20 US20040119629A1 2004-06-24 John P. Hinsverk
The present invention is a multi-piece barrel shroud which provides IR signature and radar backscatter reduction over the entire length of the barrel by utilization of special radar absorbing materials and shaped in accordance with commonly known radar signature reduction techniques. The interior of the shroud includes cooling passages for the circulation of ambient air by way of a forced air circulation system which provides IR reduction. To facilitate barrel movement while minimizing weight, the majority of the shroud is stationary and is independent of the gun barrel. At least one other piece of the shroud is attached to the barrel near the muzzle end and designed to move in unison with the muzzle during recoil. The recoiling portion of the shroud is sized to mate with an annular recess within the distal end of the stationary portion so as to provide continuous shielding of the barrel throughout the entire range of recoil displacement.
85 Increased accuracy firearm US10093016 2002-03-07 US20030167909A1 2003-09-11 Jean-Paul Matter
A fire control system for a firearm, such as a rifle, operates a bolt action for increased rate of fire and convenience while retaining the secure locking of the firing chamber by manual bolt actions. After a controller determines that a round has been fired, one or more actuators, such as electrically actuated tooth wheels or gears, unlocks and reciprocates the bolt action to extract the spent shell and to load an unfired cartridge. Thereby, a consistent locking action is achieved avoiding the inconsistent sealing of conventional automatic bolt actions. Consistent accuracy with increased firing rate operation is further achieved with a cooling system activated when the firearm exceeds an optimum temperature operating range.
86 Portable electric generator with thermal electric co-generator US09910563 2001-07-20 US06461752B1 2002-10-08 Fee Chan Leung
The invention is an electric generator comprising a portable electric generator and a thermal electric co-generator. The co-generator converts heat produced by the portable electric generator into electricity. In one embodiment of the present invention, the portable electric generator is a microturbine. In another embodiment, the portable electric generator is a fuel cell. In a further embodiment, the thermal electric generator comprises a hot thermocouple and a cold thermocouple.
87 High performance gun barrel US985173 1992-12-02 US5355765A 1994-10-18 Ernest Rogers
A barrel has an inner tube with a chamber at one end and a muzzle at the other. The barrel guides projectiles such as bullets as they are accelerated by a propellant. The inner tube has an aperture near its front end. Propellant passes through the aperture into a propellant chamber formed by the inner tube and an outer tube positioned about and secured to the inner tube. A plurality of ribs extend between the inner and outer tubes. Also, a coolant may be inserted into the propellant chamber to escape through the muzzle with the propellant after the projectile exits the muzzle.
88 Gun barrel cooling arrangement US123246 1987-11-20 US4982648A 1991-01-08 Johannes Bol; Manfred Schildknecht
An arrangement for cooling the gun barrel of a combat tank wherein the gun barrel is provided with helical cooling channels on its outer surface, and an insulation layer on at least the inner circumferential surfaces of the cooling channels. This reduces the IR signature of the gun barrel during combat and avoids deformation of the barrel under the influence of radiation from the sun.
89 Stock assembly kit and rifle embodying the same US695250 1985-01-28 US4663876A 1987-05-12 Robert N. Reaume
A carbine comprising an improved stock assembly kit combined with a barrel and action assembly of preselected generic style or configuration, preferably that of a U.S. M1 carbine. The improved stock assembly includes a buttstock comprised of opposed concave half-sections which embrace and capture the trigger, receiver and operating slide mechanisms of the barrel and action assembly in upside-down orientation. A trigger assembly is mounted to the barrel forwardly of the buttstock section and is coupled to the trigger mechanism of the barrel and action assembly by a trigger slide which extends through the buttstock section. A forehand stock section is comprised of an opposed pair of stock half-sections which embrace that portion of the trigger assembly which engages the barrel and form a cavity for cooling air surrounding the barrel which extends therethrough. A concial flash hider is captured by the forehand stock sections surrounding the free end of the barrel and cooperates with apertures formed in the forehand stock sections for drawing cooling air into the cavity for cooling the barrel during firing.
