An igniter system for a piece of ammunition, having at least one propellant igniter and at least one igniter element designed for transmitting ignition power and extending away from the propellant igniter. The igniter element is arranged spaced apart from the propellant igniter.

A socket driver for a perforating gun assembly. The socket driver includes a first end, and a second end opposite the first end. The second end defines an inner diameter that has a length to extend over a threaded end of the tandem sub. The socket driver is configured to mate with a shoulder along the tandem sub of the perforating gun assembly. Specifically, the socket driver includes a radial notched profile. The notched profile is configured to mate with a radial pattern of slots along the shoulder of the tandem sub. In one aspect, the socket driver is between 3 and 8 inches in length. In one aspect, the first end of the socket driver comprises an opening configured to receive a torque tool. A method of connecting ends of perforating guns using the socket driver is also provided herein.

Disclosed is a system that includes a magazine. The magazine is configured for holding and dispensing initiation devices or initiation device components having respective non-contact readable identification (ID) codes. The magazine includes one or more initiation device tracking unit(s) configured for reading the non-contact codes of the initiation devices or initiation device components for tracking the initiation devices or the initiation device components.

A portable exothermic welding ignition controller includes a housing configured to receive a first portion of a portable power tool battery with a second portion of the portable tool battery external to the housing. A circuit board is positioned within the housing and configured for electrical coupling to the portable power tool battery. An actuator is operatively engageable with the circuit board for selectively discharging power from the portable power tool battery to a connection terminal electrically coupled to the circuit board.

A booster explosive (10) comprises a canister body 12 within which is a cap well (20) having disposed therein a detonator (24). A protective sleeve (28) encloses the cap well (20) except for that portion of the cap well, the active portion (20d), which encloses the explosive end section (24a) of detonator (24). The protective sleeve serves to attenuate the force of shock waves from nearby prior explosions acting on the detonator (24). An annular air space (32) may be provided between protective sleeve (28) and cap well (20) to further attenuate the force of such shock waves. Attenuation of the shock waves reduces the likelihood of damage to detonators (24) by prior nearby explosions.

A device for depositing paste patterns on the surface of the channel of a tube, the device comprising a frame supporting a first mechanical assembly for holding, positioning and moving the tube, and a second mechanical assembly for extruding paste for depositing said paste patterns, the assemblies cooperating with one another.

A wireless electronic initiation device for a detonator via a shock tube comprises an initiation member for initiation the shock tube and an energy storage for providing initiation energy to said initiation member. The initiation device comprises also a wireless communication device with a receiver for receiving an initiation command in a wireless way from an initiation arrangement. The initiation device comprises also a controller, which is configured to determine said received initiation command and based on said received initiation command configured to activate said initiation member to ignite the detonator initiator (108) by the energy fed from the energy storage.

Embodiments of a low-voltage, non-primary explosive detonator (110) may include a detonator shell (120) having an open end (122), a closed end (124), and a hollow interior (125) between the open and closed ends. Some embodiments include a reinforcement area of the detonator shell. A pyrotechnical material is disposed within the hollow interior, and a main explosive load is disposed within the hollow interior in between the pyrotechnical material and the closed end. In some embodiments, one or both of the pyrotechnical material and the main explosive load may be multilayered, for example with a density gradient configured to accelerate eflagration. The detonator may further include a fuse head disposed at the open end and in proximity to the pyrotechnical material within the detonator shell.
