Impeded velocity signal transmission line |
摘要 |
Blasting signal transmission tube comprising a length of elongated flexible hollow tube and a self-oxidizing combustible substance disposed within the tube for transmitting a blasting signal along the interior of the tube length, the hollow tube having a varying interior axial cross-sectional area at longitudinally spaced intervals along the tube length for reducing and controlling the velocity of the blasting signal. Also, a process for producing signal transmission tube comprising forming a length of elongated flexible hollow tube of predetermined interior cross section area; depositing a self-oxidizing combustible substance within the tube for transmitting a blasting signal along the interior of the tube length without destroying the tube; and introducing a plurality of discrete restrictions reducing the predetermined hollow tube interior cross-sectional area at longitudinally spaced intervals along the tube length for reducing and controlling the velocity of the blasting signal.
