| Electronic time delay apparatuses and methods of use are disclosed. An explosive or propellant system, which may be configured as a well perforating system includes an electronic time delay assembly comprising an input subassembly, an electronic time delay circuit, and an output subassembly. The input subassembly is activated by an external stimulus, wherein an element is displaced to activate an electronic time delay circuit. The electronic time delay circuit comprises a time delay device coupled with a voltage firing circuit. The electronic time delay circuit counts a time delay, and, upon completion, raises a voltage until a threshold firing voltage is exceeded. Upon exceeding the threshold firing voltage, a voltage trigger switch will break down to transfer energy to an electric initiator to initiate an explosive booster within the output subassembly. The explosive booster provides a detonation output to initiate the next element explosive or propellant element, such as an array of shaped charges in the well perforating system. | ||||||

| An electrical delay detonator for use in blasting initiation systems energized by a non-electric impulse signal transmitted through a non-electrical conduit, such as a shock tube, with one end inserted inside a detonator housing having redundant sensors for detecting the presence of a non-electric impulse signal and a computerized control circuit for actuating the firing circuit. An elevated voltage is generated, stored in a capacitor assembly, and discharged when fired to an electrically operable igniter. The igniter, when activated, detonates an explosive mass. A battery is also contained within the detonator housing for powering the control circuit and one sensor, in low consumption mode, for several days. Upon detecting the presence of a signal the rest of the circuits are powered up. Periodic time windows generated by the control assembly provide corresponding enabled time periods for the sensors to become operational. | ||||||

| A priming system includes a block made of pyrotechnically inert material having on one of its surfaces a cavity placed facing an explosive charge. Structure for allowing percussion of the block is mounted at a receiving surface substantially parallel to a surface where the cavity is located. The priming system can thus be completely devoid of pyrotechnic components. | ||||||

| A pressure sensor for use with a sea mine for detecting the presence of a ssing vessel by sensing a change in ambient water pressure caused by the Bernoulli effect relating to hydrodynamic flow induced by the vessel's motion. The sensor emits a responsive signal which can be used alone, or with signals from other influence sensors (acoustic and magnetic), to determine when the sea mine shoud be exploded. The sensor provides for equal sensitivity independent of the ambient pressure of the water at various depths at which sea mines may be planted, and employs electrical filters to eliminate noise. | ||||||
| 72 | Ignitor for starting fires | US752558 | 1976-12-20 | US4086049A | 1978-04-25 | Bernard August Swanson |
| A device for igniting orchard heaters or the like consisting of a housing carrying a repeatable hammer with firing pin for firing an explosive primer to light the fuel/gas of the heater. The hammer and firing pin is contained within a cylinder which is driven by an associated fluid (fuel/gas) pressure source and the displacement of the cylinder causes compression of the spring for activating the hammer. A plurality of primers is contained in a disc which rotates and aligns a new primer before the firing pin after each firing is completed. The rotation of the disc is caused by the displacement of the cylinder. | ||||||

| A safe and arm mechanism is provided employing in combination a pressure-responsive diaphragm and a variable volume chamber which are adaptable to change the mechanism from the ''''safe'''' configuration to the ''''armed'''' configuration. In the ''''safe'''' configuration gas pressure resulting from accidental ignition of a squib is insufficient to rupture the pressure-responsive diaphragm protecting the device in which the safe and arm mechanism is employed. In the ''''armed'''' configuration the available volume of the variable volume chamber is reduced and ignition of a squib within the mechanism ruptures the pressureresponsive diaphragm allowing the squib gases to initiate an igniter.
