Embodiments are described for a self-igniting assembly having a main portion with a match-like component affixed thereto. A flammable member such as a wick or match-like member is in communication with the match-like component. A handle permits the user to grip the main portion and tug the main portion to impart friction and a chemical reaction between the match-like component to ignite the flammable member. This assembly may be provided with a number of ignitable device such as logs, fire starters, fireworks, or candles.

Generally, embodiments of the invention can include a linear shaped charge (LSC) end cap coupling structure adapted for holding an initiator structure adapted to initiate a booster explosive material, the booster explosive material, and the LSC in abutting contact with each other. One embodiment includes a rubber body formed with cavities adapted to receive the LSC, booster, and initiator structure (e.g., detonation cord). One internal cavity can be formed with a plurality of flexible protrusions or fins which are oriented towards a center axis of the preferred embodiment of three cavities configured to impart an interference fit with the initiator structure. Methods related to the invention are also provided.

An apparatus and process for fracturing wells is provided. In one example, an apparatus includes an electric liquid monopropellant device including a volume of electric liquid monopropellant and a detonation cord in proximity to the electric liquid monopropellant device to ignite the volume of electric liquid monopropellant upon activation of the detonation cord. The detonation cord is adapted to ignite the electric liquid monopropellant at pressures exceeding 200 psi, and in some examples, exceeding 500 or 1,000 psi. The detonation cord can be wrapped around the electric liquid monopropellant device in a variety of configurations to increase combustion rates and/or shape the event pulse of the combustion.

Initiator modules for munitions control systems include a mounting portion for receiving a portion of an initiation device, a detonator device disposed within the initiator module, a connection portion configured to connect the initiator module with a munitions control system, and an electronics assembly configured to electronically couple with a munitions control system and transmit a signal to the detonator device. Munitions systems may include initiator modules received in a socket of a munitions control system. Methods of igniting explosive devices include coupling a shock tube to an explosive device, connecting an initiator module to a munitions control system, mounting a portion of the shock tube to the initiator module, and igniting the shock tube with a detonator device disposed within the initiator module.

An energy transfer device (10) is provided that is capable of transferring the energy output from one pyrotechnic device (52) to another device (78) for initiating firing thereof. Device (10) comprises a device housing (12) in which a deformable device insert (14) is received. Device insert (14) comprises a central passageway (34) for transmitting the output from a pyrotechnic device (52), including energy, gasses, and/or solids, to another pyrotechnic device (78). The passageway (34) conducts the pyrotechnic device output to a precise location on the second pyrotechnic device (78) where firing is most effectively initiated. The energy transfer device (10) may be employed as a part of a tool (44) used in well completion operations.
