Abstract: A linear ignition system for a metal-sheathed linear explosive including in one embodiment the ends of two metal-sheathed linear explosives are connected by a non-electrically conductive sleeve leaving a gap between the ends, and a Pyrofuze® bridge connects the metal-sheath of one end to the metal sheath of the other end. Electrical contacts are made to the two metal sheaths and application of current to the electrical contacts ignites the Pyrofuze® bridge and the linear explosives. Embodiments can also include an explosive mixture in the gap, using a hotwire bridge, or including booster increments for initiating detonating explosives. The linear ignition systems offer robust, easy-to-install linear explosive devices for applications in automotive, commercial or military aircraft safety systems, other military and aerospace applications, and commercial blasting.

Abstract: The present invention is a linear ignition system for a metal-sheathed linear explosive. In one embodiment of the invention, the ends of two metal-sheathed linear explosives are connected by a non-electrically conductive sleeve leaving a gap between the ends, and a Pyrofuze® bridge connects the metal-sheath of one end to the metal sheath of the other end. Electrical contacts are made to the two metal sheaths and application of current to the electrical contacts ignites the Pyrofuze® bridge and the linear explosives. Embodiments including an explosive mixture in the gap, using a hotwire bridge, or including booster increments for initiating detonating explosives, are also described. The linear ignition systems of the present invention offer robust, easy-to-install linear explosive devices for applications in automotive, commercial or military aircraft safety systems, other military and aerospace applications, and commercial blasting.

Abstract: A binary, ternary and/or quaternary substantially lead-free tin alloy composition that may be used as outer sheath material in various explosive-pyrotechnic linear products, such as ignition cord, mild detonating cord (MDC) and linear shaped charge (LSC).
