ABSTRACT:
A signal transmission tube assembly includes a signal transmission tube, such as a coil of shock tube on a spool, having opposite terminal ends and containing a reactive material. The open terminal ends of the shock tube provide the sole exits for the signal generated therein and the sole entry points for contaminants. Sealing means seal both terminal ends of the signal transmission tube against escape from the assembly of the signal engendered by initiated reaction of the reactive material, and protects the interior of the signal transmission tube from contamination. The sealing means may be a releasable sealing means which can be actuated to release the transmission tube from it, thereby facilitating re-use of the sealing means. Further, the sealing means may comprise a surge chamber to relieve pressure engendered by reaction of the reactive material and thereby militate against rupture of the signal transmission tube and consequent release from the assembly of a signal. A signal-rupturable diaphragm may be interposed between the signal transmission tube and the surge chamber.
