    Abstract: A loading tube is configured to receive one or more shaped charges to form a perforating gun. The loading tube includes a tubular body extending along a longitudinal axis; a cord passage formed into the tubular body; a retention cutoff formed into the tubular body and configured to receive a detonator cord; and a holding element extending into the retention cutoff and being integrally made with a wall of the tubular body, wherein the holding element is configured to hold the detonator cord into the retention cutoff. The cord passage is configured to receive the detonator cord from a bore of the tubular body and to direct the detonator cord outside the bore of the tubular body.

    Abstract: Disclosed is a firing device for shock tube. Shock tube is a non-electric explosive initiator, well known to those of ordinary skill in the art. The firing device is configured to provide a redundant dual-ignition capability for connected shock tube. In this way, a second attempt to initiate the shock tube can be made immediately following a failed first attempt. To provide this functionality, the firing device includes a primer tray that can be preloaded with two primers. Using an operably connected selector, the primer tray can be rotated between use positions that individually locate each primer for detonation.

    Abstract: A blasting system with automated detonator logging eliminates on-the-field manual logging of each detonator. Detonators are connected in sequence in an auto-logging circuit, and the blast machine initiates a logging operation in which each detonator receives and confirms an assigned sequence number along with assigned delay data. Elimination of manual logging by individuals increases safety in the blast zone and facilitates the blasting operation. The operation is simplified, likelihood of human error is reduced, and the cost of a separate logger device is eliminated. An auto-logging protocol may be incorporated into the control module of the electronic detonator. Alternately, an auto-logging module may be connected externally to each detonator similar to the conventional surface plus down-the-hole delay systems. The inventive system may include an IDC connector that facilitates the serial connection of the detonators for the logging circuit while allowing parallel connections of the blast control circuit.
