Patent number: 7421949Abstract: A novel transfer ordnance line and novel end fittings for the transfer line for use in space vehicles, aircraft, missile systems and other military applications. The transfer line is a Rapid Deflagrating Cord (RDC) hermetically encapsulated in a metal tubing. The metal tubing terminates at end fittings such as a loaded high energy (HE) end fitting which detonates, a low energy (LE) end fitting which burns, and a percussion primer used to start burning of the RDC in the transfer line. The transfer line is constructed so that gases produced during the burning of the RDC do not escape and pose a threat to the surroundings during functioning and so moisture does not enter the system during shelf life, transportation, or at any other time prior to functioning. With minor adjustments to the transfer tube and the end fittings, the transfer tubing can be made flexible by forming a coil.Type: GrantFiled: March 5, 2007Date of Patent: September 9, 2008Assignee: McCormick Selph, Inc.Inventor: Lynn G.

Patent number: 7086629Abstract: The present invention involve a method for severance of materials made of polycarbonate, polycarbonate laminate and aciylic/polycarbonate laminate, a canopy fracturing system and a conopy having the canopy fracturing system. The present invention utilizes a linear shaped explosive charge placed at a predetermined distance or stand off from the polycarbonate material to be severed. The coreload of the charge is determined such that the minimum coreload necessary to effect severance of a given thickness of polycarbonate material is utilized. A retainer is placed around the charge and affixed to the material such that the charge is at the proper stand off from the material. The retainer surrounds the back side of the charges but leaves open space between the charge and the material to be severed. Upon detonation, the charge creates an explosive cutting force, or jet blast, that severs the polycarbonate material.Type: GrantFiled: March 14, 2003Date of Patent: August 8, 2006Assignee: McCormick Selph, Inc.Inventors: Lynn G. Hilden, Douglas D. Menzel, Raymond D. Weiss

Upon detonation, the charge creates an explosive cutting force, or jet blast, that severs the polycarbonate material. Also, provided are methods for intersecting explosive charges about a pattern to be severed and methods for transferring detonation between such intersecting explosive charges.Type: GrantFiled: December 22, 1999Date of Patent: August 26, 2003Assignee: McCormick Selph, Inc.Inventors: Lynn G.

Patent number: 6467415Abstract: 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.Type: GrantFiled: February 22, 2002Date of Patent: October 22, 2002Assignee: McCormick Selph, Inc.Inventors: Doug Menzel, Stanley Rodney
