  "abstract": "A dearmer positioning system has two assemblies, each of which circumscribes a dearmer's barrel. Each of the two assemblies includes two half rings and a one-piece outer ring. The two half rings are joined to one another to define a full ring having a first central opening defining a first diameter. The full ring has a periphery defining a second diameter. The one-piece outer ring has a second central opening defining a third diameter, and a periphery defining a fourth diameter. The third diameter is greater than the second diameter such that the full ring slidingly fits in the central opening of the outer ring. Threaded fasteners engage the outer ring and extend radially through the outer ring and into its central opening to engage the periphery of the full ring.",

  "description_excerpt": "The invention described herein was made in the performance of official duties by employees of the Department of the Navy and may be manufactured, used, licensed by or for the Government for any governmental purpose without payment of any royalties thereon.\n\nThe invention relates generally to explosive ordnance disposal tools, and more particularly to a system for positioning a dearmer centrally in a gun barrel.\n\nExplosive ordinance disposal (EOD) includes the removal of projectiles that have gotten stuck in the barrel of an artillery gun. When projectiles are stuck, EOD personnel generally place a dearmer barrel near the stuck projectile in the gun's barrel. A dearmer barrel houses an explosive that, when detonated, acts to dislodge the stuck projectile. Proper positioning of the dearmer barrel in the gun barrel is critical regardless of the gun barrel's caliber.\n\nAccordingly, it is an object of the present invention to provide a dearmer positioning system.\n\nAnother object of the present invention is to provide a dearmer positioning system that is adaptable to a variety of gun barrel calibers.\n\nOther objects and advantages of the present invention will become more obvious hereinafter in the specification and drawings.\n\nIn accordance with the present invention, a dearmer positioning system has two assemblies, each of which is adapted to circumscribe a dearmer. Each of the two assemblies includes two half rings and a one-piece outer ring. The two half rings are joined to one another to define a full ring having a central opening defining a first diameter. The full ring has a periphery defining a second diameter.",
