| (57)【要約】 銃砲身を直接冷却することなしに、銃砲身の赤外線サインを著しく減少させることができる銃砲身シュラウド装置である。 銃砲身の周囲にはシュラウドが配置されているが、このシュラウドは銃砲身とは接触していない。 シュラウド自体を冷却すべくシュラウドを通して空気を循環させるが、非常に高温の銃砲身はシュラウドから空気が流出するときにも空気によってわずかしか冷却されない。 シュラウドは銃砲身とは接触していないため、シュラウドは軽量で単純なデザインで製造することができる。 発砲の際の銃砲身の後座動作はシュラウドによって補償する必要がない。 | ||||||

| 4 | A METHOD AND A DEVICE FOR NOISE REDUCTION | EP04714532.1 | 2004-02-25 | EP1597531A1 | 2005-11-23 | WIDEN, Gunnar |
| The invention relates to a method and a device for reducing noise from a gun. According to the invention, propellant gases escaping through the muzzle (3) of the gun’s barrel (5) in connection with a firing are cooled by means of a coolant (2) in liquid or crystalline state to such an extent that a noise reducing pressure reduction of the propellant gases is obtained. | ||||||
| 5 | GUN BARREL SHROUDING SYSTEM | EP97928880 | 1997-06-10 | EP0901603A4 | 2000-08-02 | ADAMS NATHAN G; GEILER KAL V |
| A gun barrel shrouding system (11) is capable of significantly reducing the infrared signature of a gun barrel, without directly cooling the gun barrel. A shroud (21) is placed around the gun barrel, but the shroud (21) does not contact the gun barrel. Air is circulated through the shroud (21) to cool the shroud (21) itself, but the very hot gun barrel is only partially cooled by the air as the air exits the shroud (21). Since the shroud (21) does not contact the gun barrel, the shroud (21) may be manufactured of a lightweight and simple design, and the recoil action of the gun barrel upon firing does not need to be compensated for by the shroud (21). | ||||||

| Methods for directing a casing are provided. The method can include firing a firearm. The firearm can comprise an upper receiver having a bore disposed therein. The bore can extend along a longitudinal axis of the upper receiver. The upper receiver can also include an ejection port disposed through a first side of the upper receiver. The upper receiver can also include a deflector extending from the upper receiver at a first end of the ejection port. The deflector can be designed to direct the casing in a forward direction. | ||||||

| A firearm barrel cooling system comprising a plurality of fins adapted to extend around and from a solid barrel of a same material as the fins is disclosed. An outside major diameter of the fins is greater than an outside diameter of the barrel at any point of the barrel. A plurality of inverted fins are defined around and in the solid barrel between adjacent fins wherein an inside diameter of the inverted fins is equal to a minor diameter of the fins and equal to or greater than an outside diameter of the barrel. A plurality of cooling sections are located between a barrel collar and a muzzle end of the solid barrel, each cooling section having a plurality of fins having a major outer diameter and a minor inner diameter. A method for cooling a firearm barrel system is also included. | ||||||

| 11 | Machine gun gas actuating and evacuation system | US3715955D | 1970-02-12 | US3715955A | 1973-02-13 | FOLLEY C; ROCHA J |
| In a machine gun having a gas-actuating system including a gas cylinder responsive to gas pressure generated by the discharge of a round and including a receiver and a barrel mounted therein having a predetermined bore and a muzzle, a novel gas evacuation means, a novel barrel extension means and a novel gas seal means all for removing exhausted gas from the area surrounding the machine gun receiver, gas cylinder and receiver. The novel gas evacuation means, mounted on the gas cylinder and along the barrel, is in communication with the gas-actuating system for removing exhausted gas therefrom and conveying said exhausted gas for discharge at a location remote from the muzzle; the novel barrel extension is attached to the muzzle of the barrel, has a bore greater than the barrel bore for removing exhausted gas from the muzzle and conveying said exhausted gas for discharge at a location remote therefrom free from interference with the operation of the gun mechanism; and the novel gas seal means includes an obturating nut and sealing collar provided in the gas-actuating system for preventing exhausted gas from passing rearwardly therethrough and escaping from the receiver.
