| 41 | Fuze explosive ordance disposal circuit | US10441665 | 2003-05-20 | US20040231547A1 | 2004-11-25 | Robert E. Keil |
| The present invention comprises an electronic Explosive Ordnance Disposal (EOD) circuit which is desirably used with fuzed explosive weapons, such as projectiles having a nominal mission time. After expiration of the mission time, if the explosive has not detonated, the inventive circuit controls the energy supplied to the fuze detonation circuit to a level that is less than a threshold level required by the fuze for detonation, thereby preventing subsequent detonation of the explosive. | ||||||
| 42 | Missile attitude safing system | US423641 | 1964-12-28 | US5886339A | 1999-03-23 | Robert R. Wilson |
| An attitude sensing safing system for a missile, which senses an attitude ror of the missile, and activates a dudding signal when the error exceeds a certain value for a predetermined time. The missile includes a delay arming timer, which is deactivated when by the dudding signal. The system allows the missile to correct itself, by requiring that the error signals persist for a set time. | ||||||
| 43 | System for self destruction of a carrier shell submunition by chemical attack | US070220 | 1993-06-02 | US5373790A | 1994-12-20 | Patrice H. Chemiere; Jean-Paul A. Dupuy; Bernard F. Bayard; Jean-Pierre Ruet |
| A mechanical system for self-destruction of a munition, in particular a carrier shell submunition, is provided in a munition having a warhead initiated by a pyrotechnic sequence, a main striker and a priming device composed of a slide movable between a safety position and an armed position and which has a device for priming the charge. The self destruction system includes a secondary striker mounted inside a receptacle of a slide and a control device to release the secondary striker after a preset delay. Secondary striker is integral with a holding element and held abutting a seat by the urging of an arming spring. The control device of the secondary striker has a corrosive agent designed to chemically attack the holding element to release it from its seat. When the holding element is released, secondary striker is translationally moved to contact the detonator to destroy the munition. | ||||||

| A pyrotechnic chain igniter device for cargo warhead sub-ammunition including an explosive charge contained in an enclosure, comprising a first striker mobile in a longitudinal bore of a body for striking a primer, a slider carrying the primer, the slider being slidably mounted in a transverse groove in the body and being adapted for sliding between a safety position and an armed position, wherein the safety position is defined by the slider being misaligned with the first striker and the armed position is defined by the primer being substantially aligned with the first striker. The first striker is adapted for striking the primer when the slider is in the armed position and when the sub-ammunition impacts a target. At least one device for blocking the slider in the safety position is provided. A trigger is pivotally mounted to the body, and a spring is provided for maintaining the trigger in a first position to prevent the slider from moving into the armed position, and for allowing the trigger to move to a second position upon axial rotary movement of the sub-ammunition thereby allowing the slider to move into the armed position. | ||||||

| 46 | Sequentially interlocked arming device | US3734022D | 1971-06-21 | US3734022A | 1973-05-22 | BOWERS R; WARPENBURG N |
| A sequentially interlocked arming device for providing the capability for the dudding of a fuze if arming events do not occur in the programmed sequence is disclosed. The sequentially interlocked arming device comprises a retardation sensor, timing delay, an out-of-line explosive train (slider), and an interlock lever which prevents the rotational movement of the slider into in-line position in the absence of a proper sequence of arming functions to prevent premature initiation of the fuze.

| 47 | Fluid flow velocity actuated safety and arming device | US3710722D | 1971-03-30 | US3710722A | 1973-01-16 | DEMAS N; FABIAN G; WACK J; WAXMAN H; MARDERIAN A; MIN S; WECKER E |
| A safety and arming device having rotary electric switches and a detonator rotor contained therein and being adapted to be coupled to a remotely located associated explosive device solely by mild detonating cord. The rotary switches and detonator rotor are mounted for rotational movement on a shaft attached to a bar screw having a nut threaded thereon, the nut being restrained against rotational movement but being movable linearly along the bar screw. Centrifugal weights attached to a rotatable impeller exert a linear force against the nut proportional to fluid flow velocity across the impeller, causing the nut to slide along the bar screw and rotate the switches and detonator rotor to the armed position. A preloaded compression spring acting upon the nut in opposition to the force produced by the centrifugal weights provides velocity discrimination by biasing the nut, rotary switches and arming rotor to the safe position and permitting the rotor and switches to maintain the armed position only in the continued presence of fluid flow above a predetermined magnitude.

| 48 | Pressure actuated safety and arming device | US3675579D | 1970-02-25 | US3675579A | 1972-07-11 | MIN SHERMAN L |
| A safety and arming device having a spring biased bellows inflatable under air pressure of a predetermined magnitude. A tube is connected to the bellows and a stud is fixed to the inside of the tube. A shaft having a helical slot formed therein fits into the tube with the stud extending into the helical slot and an arming rotor is fixed to the end of the shaft. Under air pressure of a predetermined magnitude, the bellows expands and moves the tube which causes the stud, which is fixed to the inside of the tube and riding in the helical slot, to rotate the shaft and thereby rotate the arming rotor. A gear rack connected to the outside of the tube is in engagement with an escapement mechanism to limit the rate of travel of the bellows to preclude premature arming under the influence of shocks.

| An apparatus (100) includes a canine harness (101) with a radio frequency inhibitor (400). A leash (1002) can serve as a control device (102). The leash can selectively mechanically couple to the canine harness and electrically couple an actuator (114) to the radio frequency inhibitor. When the actuator is actuated, the radio frequency inhibitor is to emit one or more radio frequency inhibition signals (405), which can include the emission of all programmed signals simultaneously. Radio frequency inhibitors can also be integrated into clothing or armor (1802), as well as equipment (1901). The radio frequency inhibitor can interrupt, suppress, or halt electronic detonation communications to an explosive device. | ||||||
