| 41 | Variable supersonic mach number air heater utilizing supersonic combustion | US11970231 | 2008-01-07 | US08087229B2 | 2012-01-03 | Kenneth J. Wilson; Warren K. Jaul; Robert G. Burman; Shannon L. Fitzpatrick |
| A supersonic combustion apparatus including a fixed geometric nozzle having a converging area, throat, and a diverging area, at least one movable combination of a fuel injector and an oxygen injector where the combined fuel injector and the oxygen injector is located within the divergent area of the fixed geometric nozzle, and an exit plane adjacent and downstream to the diverging area. The exit plane Mach speed is varied by heat addition in the diverging area by introduction of a combustible fuel through the fuel injector and oxygen through the oxygen injector and then axially aligning and positioning the combination of the fuel injector and the oxygen injector along the length of the diverging area to obtain a stabilized flame at the exit plane. | ||||||
| 42 | Perforation gun pressure-actuated electrical switches and methods of use | US12229951 | 2008-08-28 | US07902469B2 | 2011-03-08 | Brian Wayne Hurst |
| Pressure-actuated electrical switches are provided that comprise a housing having a slidable piston therein. The slidable piston slides from a first position to a second position and in so doing switches an electrical path from a first electrical contact and a second electrical contact to an electrical path between the first electrical contact and a third electrical contact. Suitable applications of such switches include any application in which a pressure wave is used to actuate an electrical switch. The pressure-actuated electrical switches of the present invention are especially adapted for use in controlling successive detonations in a downhole perforation gun, as explosive gases and pressure waves are used to actuate the slidable piston so as to trigger a subsequent detonation charge. Perforation guns utilizing these pressure-actuated electrical switches and corresponding methods of use are also provided herein. | ||||||

| 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 the detonation output to initiate the next element explosive or propellant element, such as an array of shaped charges in the well perforating system. | ||||||

| 47 | Air-safed underwater fuze system for launched munitions | US206939 | 1998-12-08 | US6131516A | 2000-10-17 | Matthew J. Sanford; Keith B. Lewis |
| An air-safed underwater fuze system is provided for munitions that are to launch-deployed and water-detonated. A housing defines a first bore contiguous with a second bore. Radial ports in the housing communicate with the first bore. A first piston is slidably mounted in the first bore and a second piston is slidably mounted in the second bore and positioned flush with the first bore. Piston control means are coupled between the munitions and first piston for positioning the first piston in a first position prior to launch in which the first piston seals off the radial ports while being spaced apart from the second piston to define a chamber. The piston control means moves the first piston at launch to a second position so that the chamber expands and the radial ports are in communication with the chamber. The piston control means further drives the first piston from its second position towards its first position at a specified time after launch. Once the first piston seals off the radial ports, the first piston pressurizes the water in the chamber. As a result, the second piston is driven along the second bore as actuating movement. A firing mechanism is provided in communication with the second bore and coupled to the munitions. The firing mechanism is responsive to the actuating movement of the second piston to generate detonation energy for the munitions. | ||||||
| 48 | Actuator lock | US163127 | 1993-12-07 | US5406879A | 1995-04-18 | Steven J. Willacy |
| An actuator lock is provided to prevent movement of an actuator until the actuator lock is released. A first member of the lock is movable in response to fluid pressure within a chamber to move from a locked position to an unlocked position allowing the actuator to move. The first member is held at the unlock position by a latching member so that the lock cannot return to the locked position. During testing of the actuator, a test member is operable to reversibly move the first member from the locked position to an unlocked and unlatched position. | ||||||

| A blasting cap is detonated to convey a shock wave to thereby initiate the explosion of an explosive charge by means of a remotely operable pressurized fluid operated blasting cap detonating device including a fluid pressure operating piston, a compression spring operable to absorb energy from the piston, and a striking pin operable for release by engagement thereof by the piston and then operable for final movement in response to force from the compression spring. | ||||||

| A salvage switch having a case which has therein a cartridge for containing a gas, an actuator and a spring for holding the cartridge in an inoperative position. Located beneath the case is a container having a hollow pin and containing a hydride. Upon actuation of the actuator the cartridge is forced forward against the force of the spring into an operative position wherein the hollow pin penetrates the cartridge. | ||||||

| 1. In an ordnance missile, a proximity-type ordnance fuze adapted to detonate said missile when said missile passes through the shock-wave front produced by a high velocity target, said fuze comprising in combination: a pressure-sensitive switch; said switch comprising a cylindrical housing, a perforated electrically conductive diaphragm mounted in said housing, the diameter of said diaphragm being substantially normal to the axis of said missile and the longitudinal axis of said cylindrical housing, one end of said housing being internally threaded an externally threaded ring adapted to mate with the threaded end of said housing and movable therein in a direction parallel to said axis of said missile, said ring and diaphragm being positioned such that movement of said ring in said direction causes said ring to press against said diaphragm thereby increasing the tension of said diaphragm, an electrical contact fixed in said housing substantially perpendicular to the diameter of said diaphragm, said contact extending adjacent to and spaced from said diaphragm, said contact being insulated from said housing, said diaphragm being sufficiently flexible so that said diaphragm can contact said contact as a result of abrupt changes in pressure encountered when said missile passes through said shockwave front; detonation means adapted to detonate said missile in response to the application of a firing signal thereto; and an energy source connected in series with said detonation means and said switch, the contacting of said diaphragm and contact causing a firing signal to be applied by said energy source to said detonation means thereby causing detonation of said missile.

| A safety and arming device activated by contact with a liquid activator and armed by the evaporation of the liquid. An element of the device expands when contacted by the liquid activator and contracts when the liquid evaporates; the expansion of this element collapses a member and the element''s subsequent contraction activates a switch which arms the device.
