摘要： A coreless-coil shock tube package system includes a "coreless" bundle of shock tubing, meaning that the tubing is not wrapped around a spool. The bundle may be a generally cylindrical coil of shock tubing. Optionally, two washer-like end plates abut the ends of the tubing coil for axial support. A self-adhesive tape covering partially covers the coil and end plates. A detonator is attached to one end of the tubing and lies tucked into the coil, through an end plate, for storage and transport. An igniter is attached to the tubing's other end. In use, the detonator is removed from the coil and attached to an explosive device. Then, the package is pulled away from the detonator and explosive, thereby uncoiling the tubing through the end plate for deployment. The igniter is actuated for igniting the shock tubing and activating the detonator and explosive.

摘要： This invention relates to protective circuitry (12) for electrical initiation elements (10) and finds utility in preventing inadvertent functioning of electrical bridge-initiation elements, such as semiconductor bridges (SCBs), bridgewires, etc., by transient environmental electrical signals. The protective circuitry (12) of this invention comprises a timer portion (14) and a clamping portion (16) and is designed to divert from the electrical initiation element (10) at least a portion of an electrical signal received at the input nodes (10a, 10b) thereof for a suitable time interval that corresponds to the duration of an expected transient signal, which is typically significantly smaller than the duration of a proper initiation signal.

摘要： A heat generating structure includes a substrate of a first material and a second material coating at least a portion and preferably all of the first material, where the second material is different from the first material. The structure also includes an additional material or compound such as ammonia borane that is impregnated or located within the structure. When the structure is thermally energized, the first and second materials react with each other in an exothermic and self-sustaining reaction that pyrolyzes the impregnated ammonia borane compound to create a target gas, for example, hydrogen from the ammonia borane. An additional material, for example, a thermite, may be interposed between the structure and the ammonia borane to facilitate the ignition of the ammonia borane.

摘要： This invention relates to a detonating cord (10) having a core (12) of reactive material and a composite jacket around the core, and the method of its manufacture. The composite jacket includes an interior jacket (14) in contact with the core and a sacrificial jacket (20) disposed over the interior jacket. The sacrificial jacket prevents the cord from being cut off by the detonation of another detonating cord of like core load disposed adjacent thereto. The sacrificial jacket is separable from the interior jacket beneath it under the force of the adjacent detonating cord, thus absorbing energy and allowing the first detonating cord to remain intact. The detonating cord may have a core load of not more than 3.2 grams/meter (15 grains/ft) or, optionally, less than 1.25 g/m (6 grains/ft). The interior jacket may be free of metal jacket layers. Optionally, the outer cross-sectional diameter of the cord may be not more than about 3.8 mm (0.15 inch) so that it can be inserted into a standard detonator. The sacrificial jacket may be made from polyethylene and may have a thickness of about 0.25 mm (0.01 inch).
摘要翻译：本发明涉及一种具有反应性材料芯（12）和围绕芯的复合护套的引爆线（10）及其制造方法。复合护套包括与芯部接触的内部护套（14）和设置在内部护套上的牺牲护套（20）。牺牲护套通过与其相邻设置的类似铁芯负载的另一引爆绳的引爆来防止绳索被切断。牺牲护套可以在相邻的引爆绳的力作用下与其下方的内部护套分离，从而吸收能量并允许第一引爆绳保持完整。引爆绳可以具有不超过3.2克/米（15粒/英尺）或任选地小于1.25克/米（6粒/英尺）的核心载荷。内部护套可以没有金属护套层。可选地，帘线的外截面直径可以不大于约3.8mm（0.15英寸），使得其可以插入到标准雷管中。牺牲护套可以由聚乙烯制成，并且可以具有约0.25mm（0.01英寸）的厚度。

摘要： An initiator assembly (38) is factory-pre-assembled and comprises an initiation fixture (10) secured to a triggering device (40). The initiation fixture (10) comprises a unitary body, i.e., one without moving parts, and includes a bushing groove (18) to receive as an accessory an O-ring (64) to seal the device within the barrel (42) of the triggering device (40). A fuse/fixture sub-assembly (34) includes an initiation charge (30) disposed at the firing face (13a) and a signal-transmission fuse (22). The initiation fixture (110) maybe a "universal" fixture having thereon optional external threads (36) and being otherwise dimensioned and configured to be received within either an internally threaded barrel (42) of a triggering device (40) or the barrel (42) of a triggering device which utilizes a fuse-holding cap (56). The initiator assembly (38) may include a spool (66) on which the signal-transmission tube (22) is wound.
