Abstract
A signal transmission fuse (10, 20) such as shock tube has an outside diameter (OD) not greater than about 2.380 mm (0.0937 inch), for example, a tube outside diameter (OD) of from about 0.397 to 2.380 mm (about 0.0156 to 0.0937 inch), and the ratio of the inside diameter (ID) of the tube to the radial thickness of the tube wall (T) is from about 0.18 to 2.5. The inside diameter (ID) of the tube may be from about 0.198 to 1.321 mm (about 0.0078 to 0.0520 inch). The powder surface density of the reactive material contained within the bore (16, 30) of the fuse (10, 20) may, but need not, be significantly less than that which the prior art considers to be a minimum acceptable powder surface density. Other things, such as the cost of the material used being equal, signal transmission fuse (10, 20) of the present invention is lower in cost than conventional standard sized fuse because of its reduced diameter, and yet has good stiffness and tensile strength so as to enable it to be successfully deployed and used in the same manner as standard size signal transmission fuse.
