| An explosive device contains a water-reactive material that ignites upon exposure to water. The water-reactive material ignites a water-activated fuse that has a predetermined burn rate and length. The predetermined burn rate and length allows the device to sink to a desired depth before exploding. Hence, the device explodes after a desired period of time and/or at a desired depth. Defense against underwater swimmers is an advantageous feature of embodiments of the disclosure. The device can use a forty millimeter (40 mm) form factor, which permits launch of the device from convention grenade launchers. | ||||||

| A pressure switch is provided to arm a munition's fuze mechanism upon launch. The switch operation is based upon extreme gas pressures experienced during launch of the munition. The switch includes a piston contained in a housing. The piston translates due to launch pressures. The piston translation then causes a copper puck component to contact nearby electrical stab pins, to close a circuit. The closed circuit is then used to electrically arm the fuze mechanism. | ||||||

| A combustion device has a controllable venting mechanism, within a piston/plunger or a chamber/housing, to allow the flow of air out of the chamber to enable the piston/plunger to be freely inserted for the purpose of storage or to maintain the air within the chamber to enable the piston/plunger to create a pressure necessary for combustion. | ||||||
| 50 | Underwater electromechanical timer | US10033753 | 2001-12-19 | US06533451B1 | 2003-03-18 | Ruey-Shan Liu |
| An underwater electromechanical timer comprises a motor-driven timer assembly which includes a threaded member that engages an endless screw driven in rotation by means of a motor. Time programming of the timer is accomplished via presetting a length of sliding of the threaded member along the endless screw. The sliding threaded member causes a timely switching event of a device switch placed in the casing structure. The device switch, electrically connected to an external device, thereby activates the external device. The underwater electromechanical timer is activated via an activation mechanism that is externally exposed. Under an external pressure, the activation mechanism connects an output of the motor with the endless screw, and further turns on the motor. Resilient elements are further mounted between the motor and the endless screw and between the threaded member and the device switch to prevent undesired activation events. | ||||||
| 51 | Fluid activated detonating system | US343459 | 1996-03-18 | US5632348A | 1997-05-27 | Malak E. Yunan |
| A fluid actuated detonating device is shown being used to activate explosive devices in a borehole. The detonating device has an explosive detonation charge arranged in a housing wherein a rupture disc in the wall of the housing separates the explosive charge from a fluid environment so that when pressure in the fluid environment is raised to a sufficient level the rupture disc fails and communicates a sudden pressure wave to the explosive to detonate the explosive. | ||||||
| 52 | Dual actuation harness fitting release | US482755 | 1990-02-21 | US5036660A | 1991-08-06 | Armand J. Aronne |
| Aviator harness fittings are pneutically actuated by a central device including a pressurized gas cartridge. A firing pin may mechanically pierce the cartridge or automatic ballistic actuation of the firing pin may be accomplished by SEA WARS gas-generating devices when the latter contacts sea water. The ballistic actuation of the present invention requires two separate SEA WAR gas-generating devices to fire simultaneously thereby minimizing the chance of false actuation. | ||||||
| 53 | Depth charge fuze | US346419 | 1989-05-01 | US4911058A | 1990-03-27 | Sten E. O Andersson; Jan T. Olsson; Jan Bjork |
| A depth charge fuze includes a piston in a cylinder sealingly and displaceably guided to actuate a firing mechanism against atmospheric pressure within the cylinder on one side of the piston. The piston is operatively connected to a balancing device for balancing in axial direction. At the other side of the piston there is provided a pressure chamber connected to the surroundings by means of a number of throttling passages with valves depending on the surrounding water pressure for closing up the passages on different levels of water pressure. A shearing means retains the piston in a rest position up to a predetermined maximum pressure drop over the piston. | ||||||
| 54 | Safe/arm device | US145000 | 1988-01-15 | USH492H | 1988-07-05 | Jerome A. Kong; David L. Riggs |
| A safe/arm device has a rotor that aligns or misaligns a path for an explve. The rotor is aligned by the effects of a fluid pressure differential acting upon a piston of the device. This pressure differential causes the piston to translationally move and this movement is transmitted to the rotor by a shaft. The shaft fits within an axial bore defined by the rotor. This axial bore in turn defines a helical groove. A ball, partially recessed within a well defined by the shaft, rides within this helical groove. As the shaft is translationally driven within the axial bore, the helical groove of the rotor tracks the ball. Translational movement of the shaft is thereby converted to rotational movement of the rotor. As a safeguard, the shaft is split into two sections, one in engagement with the piston and the other in engagement with the rotor. By this arrangement, a predetermined amount of movement of the piston is required before this movement is transmitted to the rotor. Further, a detent mechanism has been incorporated in the device to keep the rotor locked in place until there has been sufficient piston movement. | ||||||

| A safety fuse for an underwater explosive, including a piston shiftable longitudinally to detonate the explosive, a diaphragm attached to the piston such that pressure on one side of the diaphragm moves the piston to detonate the explosive and ports communicating with one side of the diaphragm and the exterior of the fuse device for transmitting water pressure to that side of the diaphragm, thereby shifting the piston to detonate the explosive; safety devices which must be removed in order to enable water under pressure to contact the one side of the diaphragm; appropriate spring operated means for driving the piston to detonate the explosive; other protective means against inadvertent detonation. | ||||||

| A depth charge igniter has a circumferential water pressure actuated shear pin between the cover and movable plunger adopted to hit a percussion cap, which shear pin may be adjustably engaged along its circumferential length to set a predetermined detonation depth. | ||||||
| 57 | Hydrostatic delay action fuse | US6491470 | 1970-07-29 | US3884150A | 1975-05-20 | BRENNAN JOHN A |
| A hydrostatically operated fuse having a pressure sensitive movable piston fixed to a rack and pinion gear arrangement. The movement of the piston corresponding to the working depth of the fuse is transmitted by the gears to a rotating cam device which may be preset to actuate a spring driven runaway escapement mechanism at any one of a number of selected depths represented by the size of the arc through which the cam must turn. The escapement mechanism controls a firing pin release mechanism which is actuated a predetermined time interval subsequent to the escapement actuation. A soluble salt washer device prevents the pressure sensitive piston from being exposed to the ambient pressure for a predetermined time.

| 59 | Explosive bolt | US3754496D | 1971-08-20 | US3754496A | 1973-08-28 | NOEL E |
| An explosive bolt which is initiated in response to a predetermined hydrostatic pressure including a percussion sensitive bolt filled with explosive having a hydrostatic pressure responsive detonator attached thereto. The detonator includes a plunger having a firing pin attached thereto, the plunger normally being constrained in a retaining sleeve by a ball detent. A piston is slidably positioned over the retaining sleeve and prevents the detent from releasing the plunger until the piston has moved under sufficient hydrostatic pressure. A spring is provided between the plunger and the piston which becomes compressed as the piston moves under pressure thereby providing a forward biasing to the plunger.

| A bomb-type underwater signal source is disclosed having a detonating mechanism wherein the rupture of a shear disk assembly at a predetermined ocean depth permits the ambient hydrostatic pressure to compress the gas within a cavity and raise the temperature at one end of this cavity to a level sufficient to detonate first a confined secondary explosive positioned at this end of the cavity and then the main charge.
