Abstract: A detonator (10) has a constant-diameter shell (12) which has a significantly higher shell length-to-diameter (outside diameter) ratio than prior art detonators. The shell (12) is configured to hold an explosive output charge (18) which is cylindrical in configuration and has a charge L:D ratio which is greater than that of prior art constant diameter detonators. As a result, a significant portion of the output signal of the detonator is directed laterally and it is feasible to transfer signals to a plurality of receptor lines disposed along that portion of the length of the detonator which is co-extensive with the length of the explosive output charge (18). A connector block (26) is configured to hold at least one array of receptor lines in side-by-side arrangement along the side of the detonator (10), and transversely to the longitudinal axis of the detonator (10).

Abstract: A connector device (10, 214) for transferring a non-electric blast initiation signal from a donor line (26, 224) to an acceptor line, e.g., an input stub (24, 217) has donor line retaining means (20a, 20b, 229) for disposing a donor line (26, 224) in signal transfer relation to the input stub (24, 217). An anvil member (27, 130, 226) is provided to support input stub (24, 217) at the point where it is in signal transfer relation with the donor line (26), preferably in conforming contact with the donor line (26). In a particular embodiment, the connector device has a body portion (10a) on which is retained a detonator cap (22). Cap (22) detonates upon receipt of a detonation signal from an input stub (24), optionally after a delay period if delay elements are incorporated into the cap (22). The connector device (10) has retainer spring clips (20a, 20b) for retaining the donor line (26) in signal transfer relation to the input stub (24). An output line retaining member (16) holds the output line (28) in signal transfer relation to the detonator cap (22).

Abstract: An initiation signal transmission line tube (10a, 10b, 10', etc.), which is effective to transmit an initiation signal therethrough, contains one or more rupture lines (20a, 20b and 20c, etc.) in the tube wall. Rupture lines (20a, 20b and 20c, etc.), which may be weld seams or grooves or both, are ruptured by the initiation signal passing therethrough. The spent tube carcass is split or fragmented and therefore less troublesome as litter on a work site than an intact shock tube carcass. If the tube is extruded, a rupture line may be formed by contacting the parison (118) from which the tube is made with scoring means, e.g., a pin or blade (124a, 124b). Optionally, the scoring means may be moved radially during the extrusion process, to form serpentine, e.g., helical, rupture lines. Preferably, the rupture lines intersect periodically and, upon firing, the tube is fragmented into shards. Alternatively, the tube (50d) may be extruded in segments (62) that adhere to each other at interfaces (64) which provide rupture lines for the tube. Optionally, some segments (62) may be formed from different extrudate materials than others.

Abstract: A detonator (10) is equipped with an input lead (29) having multiple signal transmission lines (30, 31) which provide redundant initiation signals to the target charge (14) of a detonator (10, 10') thereby increasing the reliability of initiation. The multiple signal transmission lines (30, 31) may be made of shock tube and can be part of a long or short input lead (29, 129) and may be initiated by any suitable means, for example by being disposed in signal transmission relation to a detonating cord (60, 62) to improve the reliability with which a signal is transferred from the detonating cord (60, 62) to the detonator (10, 10').

Abstract: An isolation member (34) for use in a non-electric detonator cap (10) is of substantially cylindrical shape and has an interior passageway (40) extending therethrough and defining a positioning region (44) and a discharge port (56). The positioning region (44) is dimensioned and configured to snugly receive and seat therein a signal transmission line or shock tube (30) and to orient the signal-emitting end (30a) thereof to aim along the longitudinal axis of cap (10) through a rupturable diaphragm (42) at the target provided by receptor charge (14). The isolation member is positioned between and spaces the signal-emitting end (30a) of the signal transmission line (30) from the receptor charge (14) contained in the detonator cap (10). The diaphragm (42) is formed with centrally intersecting score lines (42a, 42b) that facilitate rupturing of the diaphragm by the signal. The diaphragm (42) may have a circular or polygonal, e.g., rectangular, periphery. The isolation member is preferably made of a semi-conductive material to bleed off to the shell (12) any static electricity charges transmitted through the signal transmission line (shock tube 30) so as to prevent static discharge initiation of the charge.

Abstract: A method and apparatus for transferring non-electric blasting initiation signals form detonating cord signal donor lines to signal transmission tube acceptor lines involves disposing the acceptor line in enhanced signal transfer configuration with the donor line. The acceptor line (30) may constitute the input lead (29a) of a detonator (10a). Enhanced signal transfer configuration between the input lead (29a) and the detonating cord (60) can be established by disposing input line (30) in at least partial wrap-around contact with the detonating cord (60) or in multiple abutting contact with the detonating cord (60). Enhanced signal transfer configuration can also be achieved for a detonator having at least two input lines in abutting contact with the detonating cord. A slider (44) is designed to extend contact between a detonator input lead and a detonating cord. The slider (44) provides a detonator retainer (48) for holding a detonator (10a) and a base fixture (74') that includes a pass-through aperture (58a) for a detonating cord (62). Input lead-retaining means (52) on the base fixture (74') disposes the input lead (29a) in position for enhanced signal transfer configuration with a detonating cord that may extend through the pass-through aperture (58a).

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.

Abstract: A signal transmission tube assembly includes a signal transmission tube (12), such as a coil of shock tube on a spool (10), having opposite terminal ends (14, 16) and containing a reactive material. The open terminal ends (14, 16) of the shock tube provide the sole exits for the signal generated therein and sole entry points for contaminents. Sealing means (18a, 18b) seal both terminal ends (14, 16) of the signal transmission tube (12) 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 (12) from contamination. The sealing means (18a, 18b) may be a releasable sealing means (18a, 18b) which can be actuated to release the transmission tube (12) from it, thereby facilitating re-use of the sealing means (18a, 18b). Further, the sealing means (18a, 18b) may comprise a surge chamber (25) to relieve pressure engendered by reaction of the reactive material and thereby militate against rupture of the signal transmission tube (12) and consequent release from the assembly of a signal. A signal-rupturable diaphragm (44) may be interposed between the signal transmission tube (12) and the surge chamber (25).
