089140700 | Lining, rifling, or making | 7 |
20090084255 | Compressed Elastomer Process for Autofrettage and Lining Tubes - An inventive process is provided for creating residual compressive stress at a surface of a structure without resort to custom mandrels and dangerous high-pressure fluids. The inventive process yields autofrettage of a structure such as a tube, gun barrel and the like, the structure having an outer surface and an inner surface. | 04-02-2009 |
20090320673 | GUN BARREL - A gun barrel with a gun barrel liner and a breech ring, which are joined with each other by a bayonet thread. A continuous cavity is left between adjacent bayonet ridges of the gun barrel liner and the bayonet ridges of the breech ring that are located axially behind them or in front of them. A locking segment is inserted in at least one of the cavities that is formed in the installed gun barrel liner between adjacent bayonet ridges of the gun barrel liner and the bayonet ridges of the breech ring to prevent unintentional detachment of the gun barrel liner from the breech ring. The locking segment can completely fill the corresponding cavity. | 12-31-2009 |
20110017051 | Compressed Elastomer Process for Autofrettage and Lining Tubes - An inventive process is provided for creating residual compressive stress at a surface of a structure without resort to custom mandrels and dangerous high-pressure fluids. The inventive process yields autofrettage of a structure such as a tube, gun barrel and the like, the structure having an outer surface and an inner surface. | 01-27-2011 |
20120180625 | Ordnance - A boomerang-shaped projectile, ammunition cartridge including the projectile, and a weapon barrel through which the projectile is fired. | 07-19-2012 |
20120255427 | LAUNCHER ADAPTER - A launcher adapter provides a versatile arrangement for using available launchers, e.g., standalone grenade launchers, to accommodate a variety of rounds, and can reduce the need for multiple launchers. The launcher adapter can include a durable, reusable adapter body configured to be loaded into a launcher. The adapter body can include a front portion with a charge end and charge end opening, a rear portion with a base end that includes a base end opening configured to receive a shell of a preselected type and an annular peripheral rim configured to engage the rear end of the launcher breech to prevent the adapter body from sliding out of the front end of the launcher when the adapter is loaded into the launcher, and a central bore extending through the adapter body along the longitudinal axis thereof, the central bore connecting the charge end opening and the base end opening. | 10-11-2012 |
20130239791 | APPARATUS HAVING FRICTION PREVENTING FUNCTION AND METHOD OF MANUFACTURING THE SAME - A friction preventing apparatus and a method of manufacturing the same are provided. The apparatus includes: a first object; a second object spaced apart from the first object and facing the first object; and a plurality of charged nanoparticles provided on a surface of one of the first and second objects, such that the nanoparticles are disposed between the first object and the second object. A potential difference is formed between the first and second objects. The nanoparticles may be positively charged and may adhere to the first object, and the first object has a potential lower than a potential of the second object. The nanoparticles may be negatively charged and may adhere to the second object, and the second object has a potential higher than a potential of the first object. | 09-19-2013 |
