The restraining strap has a rectangular cross section with a broad side against cylindrical sections holding a release member. The moment of inertia for a rectangular cross section strap is represented by the formula I=BH3/12. The lower moment of inertia reduces the load on the fusible link. With no limit to the number of wraps around the cylindrical sections, higher preloads can be accommodated by increasing the number of wraps of the restraining strap without affecting the moment of inertia or the amount of force borne by the fusible link. The actuator has a catch extending between the restrainer and actuator. The catch ends engage the restrainer and actuator and, upon release from the actuator, the catch rotates to allow the restrainer to unwind from about the cylindrical sections.

Single crystal shape memory alloy devices and methods
Devices and methods of making devices having one or more components made of single crystal shape memory alloy capable of large recoverable distortions, defined herein as “hyperelastic” SMA. Recoverable Strains are as large as 9 percent, and in special circumstances as large as 22 percent. Hyperelastic SMAs exhibit no creep or gradual change during repeated cycling because there are no crystal boundaries. Hyperelastic properties are inherent in the single crystal as formed: no cold work or special heat treatment is necessary. Alloy components are Cu—Al—X where X may be Ni, Fe, Co, Mn. Single crystals are pulled from melt as in the Stepanov method and quenched by rapid cooling to prevent selective precipitation of individual elemental components. Conventional methods of finishing are used: milling, turning, electro-discharge machining, abrasion. Fields of application include aerospace, military, automotive, medical devices, microelectronics, and consumer products.
The compositions of different energetic metallic particles and corresponding coatings are chosen to take advantage of the resulting exothermic alloying reactions when the metals are combined or alloyed through heat activation. Bimetallic particles composed of a core/shell structure of differing metals are chosen such that, upon achieving the melt point for at least one of the metals, a relatively substantial amount of exothermic heat of alloying is liberated. In an embodiment, the core metal is aluminum and the shell metal is nickel. The nickel may be applied to the outer surface of the aluminum particles using an electroless process from a metal salt solution with a reducing agent in an aqueous solution or a solvent media. The aluminum particles may be pretreated with zinc to remove any aluminum oxide. The resulting bimetallic particles may be utilized as an enhanced blast additive by being dispersed within an explosive material.

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.

A housing has a passageway containing a valve seat. A valve element seals against the valve seat to maintain the valve in the closed position. A release rod extends from the valve body and a shell surrounds the release rod, preventing its movement. The shell is formed in several sections, maintained together by a wire. The wire is connected to a frangible initiator which, upon failure, releases the wire from the shell, allowing these sections to move away from one another. When this occurs, the release rod and valve body are able to move, opening the valve, allowing fluid flow between the inlet and outlet of the valve.

The initiation fixture (110) may be 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-holder cap (56).

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).

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 layer of shrink-wrap or other polymer film 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.
