摘要： Slurry-loadable electrical initiators are disclosed. In one aspect, a fuel slurry and oxidizer slurry are separately prepared and then mixed (e.g., in a static mixer) into a pyrotechnic material slurry. The pyrotechnic material slurry is loaded into the initiator (e.g., by a positive displacement pump). An ignition assembly which includes a header having at least one electrically conductive pin and a bridgewire between the header and the pin are installed such that the bridgewire appropriately interfaces with the pyrotechnic material of the initiator. In another aspect, another of the electrical connectors for the header is a shell and is joined to the header by a crimped connection or by a welded connection which also interconnects the shell with the charge cup which contains the pyrotechnic material.

摘要： A column of explosive in a low-voltage detonator which makes it spark-safencludes an organic secondary explosive charge of HMX in the form of a thin pad disposed in a bore of a housing of the detonator in an ignition region of the explosive column and adjacent to an electrical ignition device at one end of the bore. The pad of secondary charge has an axial thickness within the range of twenty to thirty percent of its diameter. The explosive column also includes a first explosive charge of CP disposed in the housing bore in the ignition region of the explosive column next to the secondary charge pad on a side opposite from the ignition device. The first CP charge is loaded under sufficient pressure, 25 to 40 kpsi, to provide mechanical confinement of the pad of secondary charge and physical coupling thereof with the ignition device. The explosive column further includes a second explosive charge of CP disposed in the housing bore in a transition region of the explosive column next to the first CP charge on a side opposite from the pad of secondary charge. The second CP charge is loaded under sufficient pressure, about 10 kpsi, to allow occurrence of DDT. The first explosive CP charge has an axial thickness within the range of twenty to thirty percent of its diameter, whereas the second explosive CP charge contains a series of increments (nominally 4) each of which has an axial thickness-to-diameter ratio of one to two.

摘要： An electronic delay detonator for igniting an ignition resistor a predetermined delay time after supply of electric power from a blasting machine comprises two input terminals for receiving the electric power supplied from the blasting machine, a diode-bridge circuit connected to the input terminals, a power supply capacitor connected to the output of the diode bridge circuit, an RC charging circuit connected in parallel with the capacitor and having a predetermined time constant, and a monolithic IC. The monolithic IC includes a reference generation circuit for generating a compare reference voltage by dividing the power supply by dividing resistors, a voltage comparator for comparing the voltage charged in the capacitor of the charging circuit with the compare reference voltage, a signal latch circuit for holding the output of the comparator and a transistor current switching circuit responsive to the output of the signal latch circuit to for supplying the electric energy of the power supply capacitor to the ignition resistor of the detonator. The overall circuit is in a hybrid IC module. A resistor having a constant resistance sufficiently distinguishable from an internal resistance of the detonator is connected across the two input terminals to bypass a stray current and enable checking of connection continuity of series-connected detonators.
