    摘要: A shaped charge liner may include a plurality of liner segments for a shaped charge configured to perforate a sidewall of a wellbore upon detonation. The plurality of liner segments may include a tip liner segment comprising a first group of compacted metal powder having a hollow cone shape with a trailing interface end disposed opposite a tip end. The tip liner segment is configured to be disposed in a shaped charge casing of the shaped charge. The plurality of liner segments may also include a base liner segment comprising a second group of compacted metal powder having a truncated hollow cone shape with a trailing base end disposed opposite a leading base interface end. The trailing base end has a larger diameter than the leading base interface end, and the base liner segment is configured to be disposed at least partially within the shaped charge casing.

    摘要: A method for a vacuum process of isostatic pressing of powder material comprises preparing an explosive charged rubber bag by charging a rubber bag with powder, forming a vacuum environment by putting the explosive charged rubber bag in a vacuum box, sealing an inlet of the explosive charged rubber bag which is in a vacuum state, and maintaining the vacuum state by putting the explosive charged rubber bag in a fluid contained in a reservoir by a predetermined depth in a state that the inlet of the explosive charged rubber bag has been sealed.

    摘要: A modular hand grenade design that permits the use of compressed powders such as A-5. The hand grenade body is split into two main components—a base/sleeve and a nose cap. These two main components contain the explosive. They are loaded with explosive while still separate. The explosive is loaded into the base/sleeve and compressed to form a solid. A core sleeve is attached to the base to form a void inside the explosive where the detonating portion of a fuse assembly can be placed. Explosive is likewise loaded into the nose cap and compressed to form a solid. The nose cap is attached to the base/sleeve assembly. A fuse assembly is then attached to complete the grenade.

    摘要: A crumbly, tacky, nonfluent mass is first separated into small segments by a shredding plate operating against the mass; these segments are then formed into firm, rounded, fluent pellets by a vibrating conveyor and dispensed into a tubular case, where they are tamped into a solid mass by a reciprocating, self-adjusting tamping rod, the case being supported on a rotating table.
