摘要： The invention describes an igniter support (22) for an igniter unit (20) of a gas generator (10), comprising a first holder element (30) made from a first material and a second holder element (32) made from a second material different from the first material. The two holder elements (30, 32) can be positively coupled to each other, especially can be at least partially positively nested. Further, a subassembly (16), a gas generator (10) as well as a method for manufacturing a gas generator (10) are described.

摘要： A detonation wavefront controller for a linear shaped charge, comprising a first part and a second part. The first part comprises: a detonator holder, and a first aperture having a first width and a shape which is substantially a cyclic polygon, substantially an ellipse or substantially circular. The second part comprises: a second aperture having a second width larger than the first width. With the first part at least partly received within the second part, the first part is moveable relative to the second part to configure the detonation wavefront controller at least between: a first configuration with a first distance between the first aperture and the second aperture, and a second configuration with a second distance between the first aperture and the second aperture, the second distance larger than the first distance.

摘要： A power charge (12) for a setting tool is composed of a propellant (16) and an igniter (32) embedded in the propellant (16). The propellant (16) is a homogeneous mixture of combustible components, an oxidizer and an epoxy binder, which together provide a continuous mass of solid form. The propellant (16) has an exterior (14) which, together with an outward face (36) of the igniter (32), is exposed and provides the outer surface of the power charge (12). A protuberant rib (28) extends along the length of the exterior (14) in a spiral-shaped pattern and provides a stand-off spacer between the power charge (12) and the setting tool. The igniter (32) has a main body portion (52) and an annular-shaped protrusion (48) which extends laterally outward from the main body portion (52) and into the propellant (16) to retain the igniter (32) within the propellant (16). The entire power charge (12) is formed of combustible materials.

摘要： An initiator head assembly may include a body and an electrical contact component positioned proximal to the body. The body may include a head extending from a base, and a platform extending from the head, and the body may be injection molded as a unitary component. The electrical contact component may include a line-in portion positioned proximal to the platform and a ground portion positioned proximal to the head. The electrical contact component may be formed integrally with the body such that it is anchored in a fixed position in the body. An initiator for a perforating gun assembly may include the initiator head assembly and a shell coupled to the initiator head assembly.

摘要： The present invention relates to a device, a system and a method for retaining detonators in an explosive booster, particularly a retention device for retaining a detonator in the blind hole of a booster which allows the safe extraction thereof from the booster. The retention device comprises a flexible holding means that is movable between a blocking position retaining the detonator inside the blind hole and an open position which allows extracting the detonator from the blind hole.

摘要： This patent relates to lined shaped explosive devices, in particular it relates to linear Shaped Charges (SC), more particularly it relates to a Fluted or Scalloped Linear Shaped Charge. The fluted linear SC, unlike a standard linear SC produces hydrodynamic penetration, higher jet velocities, higher mass jets and deeper penetration. The fluted linear device disclosed herein produces greater compression and convergence of the liner material because of the partial radial collapse of the concave flutes. Further, the fluted linear SC is equipped with a simultaneous initiation of the full length of the explosive driving the liner, providing smooth detonation wave front along the full length of the fluted linear liner.

摘要： A power charge (12) for a downhole setting tool has a sleeve (14) which defines a housing. A propellant (16) is located in the sleeve (14) in solid form and defines a first end face (20). An igniter (32) is embedded into the propellant (16) first end face (20). The igniter (32) has a main body portion (52) with an end located adjacent to the first end face (20), and an annular-shaped protrusion (48) which extends laterally outward from the main body portion (52) and into the propellant (16). The annular-shaped protrusion (48) defines a shoulder (46) which engages the propellant (16) to retain the igniter (32) within the propellant (16) at the first end face (20) of the power charge (12). The sleeve (14) is formed of a combustible material which will burn when the propellant (16) is burned.

摘要： A low-cost, reliable and easy to use kit for neutralizing surface exposed landmine and unexploded ordnance for humanitarian demining is based on a liquid fuel and a solid/soluble fuel. Both fuels are premeasured in separate, sealed containers. The addition of a small quantity of solid/soluble fuel into the liquid creates an explosive. The resulting mixture is capable of detonating with a standard No. 8 blasting cap. The solid/soluble fuel can be in the form of a powder, tablet, or its saturated solution in water. The solid/soluble fuel is hexamethylenetetramine. The liquid fuel, nitromethane, is provided in premeasured quantities. User is provided instructions for choosing the appropriate quantity of liquid fuel, the corresponding solid/soluble fuel required, the method of mixing, placement and detonation of the kits. Also disclosed is a simple wooden stand to hold the bottle of explosive in place. A special fuel, liquid 2-ethylhexylnitrate, is provided to desensitize the mixed and sensitized explosive.

摘要： An automatic stovetop fire suppressor providing a gradual release of a fire suppressing agent in a desired distribution pattern and method of gradual and spatial agent release are provided herein. A plastic cone shaped lid seals on the bottom of a can and forms a closed container. The closed container is filled with a fire suppressing agent. An initiator charge breaks a designed breaking point of a reduced horizontal cross sectional area when fuse activated. The bottom lid drops down exposing a radial opening. Fire suppressing agent flows out of the radial opening, suppressing a stovetop fire with minimal or no splashing of cooking oil. An initiator housing is affixed to a top wall of the can and serves as the welding point for securing the plastic lid. A travel limiting member attached to the bottom lid catches on a shoulder of the initiator housing to limit the radial opening height.
