82 Electronic self-destruct device US10258235 2002-10-22 US20030136290A1 2003-07-24 Bertram Kolbli
The invention relates to a device for time-controlled self-destruction of a projectile by means of a batteryless, electronic self-destruct device. Several capacitors charged by a piezo element or a surge generator during firing are used in the flight phase for operational purposes. At least two of the capacitors arc connected to the input of a comparator, so that the influence of a constantly modifiable operational voltage and the influence of a discharge of modifiable voltage levels by the piezo element or surge generator does not affect the time function.
83 Fuze sterilization using sacrificial anodic component US09814485 2001-03-21 US06539872B2 2003-04-01 John Pipkin
A method of fuze sterilization is provided for a fuze that includes a first component and a second component with a prescribed relationship being defined therebetween. The prescribed relationship is one that is required for proper detonation operation of the fuze. The first and second components are fabricated from materials having different galvanic potentials. An electrolyte is introduced between the first and second components to initiate galvanic corrosion of one of the components. The galvanic corrosion continues for a period of time until the prescribed relationship between the first and second components changes sufficiently to disable the detonation operation of the fuze.

87 Safe and arm device US975034 1992-11-12 US5249526A 1993-10-05 George E. Cooksey
A safe and arm device has a cylindrical body from which a plurality of exsive leads diverge from a rotor movable through an arming angle to electrically and mechanically arm a plurality of detonators and has a rotary solenoid with a shaft oscillating a predetermined number of times when the device is to assume an armed condition. The device has an axle extending alongside the shaft, and a setback weight is mounted on and helically coupled to the axle to motivate the axle through an angle actuating the rotor through the arming angle. The shaft bears an arcuate pawl having recesses, and the axle bears an arcuate cam having recesses juxtapositioned to the pawl. Latch balls are mounted in the body between the pawl and cam for movement partially into and from the recesses. The pawl recesses are configured so that the balls are alternately motivated toward and from the cam by the oscillations, and the cam recesses are configured so that alternating engagement and disengagement by the balls releases the shaft, when motivated by the weight, to move through the actuating angle in steps corresponding to the oscillations. The cam recesses and rotor actuation are arranged to allow the device to be resafed, to be locked in both safe and armed conditions, and to minimize any intermediate condition.
88 Pyrotechnic chain igniter for cargo warhead submunition US559097 1990-07-30 US5206457A 1993-04-27 Alain R. Pascal; Patrice M. Chemiere; Jean-Paul A. Dupuy

The safety position is defined by the primer being mis-aligned with the striker and the armed position is defined by the primer being substantially aligned with the striker. The device also includes at least one means for blocking the slider in the safety position and a neutralization means including a trigger actuated by a driving means for preventing the slider to slide into the armed position. Further, the device includes a delayed self-destruct means including a second primer, a delay wick, igniter and a second striker, wherein the second striker is mounted on the slider for initiation of the second primer, the second primer being cooperable with the delay wick and igniter relay to initiate the primer.
89 Fuze for bomblet projectile US559936 1990-07-30 US5022325A 1991-06-11 Gerhard Skowasch; Udo Sabranski; Jurgen Funk; Siegfried Quick
A fuze for a bomblet projectile of the type including a primary firing pin mounted in a housing for axial displacement in the longitudinal direction and a detonation charge carried by a slide disposed in the housing for displacement in a direction transverse to said longitudinal direction of the housing, between a safety position, wherein the detonation charge is not aligned with the primary firing pin, and an armed position, wherein the detonation charge is aligned with primary firing pin. To further improve the firing and safety devices of such fuzes and permit safe pick-up of duds, a lateral recess is provided in a side surface of the slide in the form of a longitudinal groove so that the movement of the slide, if minimum centrifugal forces are no longer present, can be arrested in an intermediate position by renewed engagement of a spring tensioned safety pin in the recess. In this intermediate position the detonation charge remains off center or non-aligned with the primary firing pin, in an interrupted line of ignition. Moreover, in the intermediate position, the slide and in particular ignition element for a self-destruct charge carried by the slide, remains spaced from second firing pin disposed laterally in the housing at the armed position.
90 Self-sterilizing fire-on-the-fly bi-stable safe and arm device US426923 1989-10-26 US4986184A 1991-01-22 William B. Kude
A safe and arm device for aligning elements of an energy transfer mechanism of an ammunition fuze includes an inertial mass, an energy transfer mechanism interrupt barrier component and an energy-loadable spring, all movably mounted in a bore of a housing of the device. The inertial mass is movable for producing an arming force in response to application of a predetermined acceleration force to the housing. The bi-stable barrier component is movable from a pre-armed stable safe position to a post-armed stable sterilized position in response to the applying of the arming force to the component upon being released from its stable safe position. In moving to its stable sterilized position, the barrier component moves through an armed position in which the elements of the energy transfer mechanism are aligned in firing relation with one another during a momentary period of time. The energy-loadable spring interconnects the inertial mass and barrier component for storing the arming force produced by movement of the inertial mass and applying the arming force to the barrier component.
91 Dud de-arming device or insert for a projectile fuze US350913 1989-05-12 US4915028A 1990-04-10 Robert Apotheloz
The dud de-arming device serves to de-arm a fuze of a projectile which has remained lying on the ground or the place where it landed as a dud in order to prevent the discovered dud from still exploding when touched or moved. As to spinning projectiles the dud de-arming device should de-arm the fuze after disappearance of the projectile spin and for spinless projectiles the dud de-arming device should de-arm the fuze after a certain time following the impact deceleration of the spinless projectile. The dud de-arming device comprises a rotor which can be rotated by spring force. This rotor can assume an armed or live position due to the projectile spin or by virtue of the firing acceleration. Upon disappearance of the projectile spin or by virtue of the impact deceleration the rotor should assume a de-armed or safety position.
92 Fuzes US253631 1988-10-06 US4876961A 1989-10-31 Bert .ANG.strom; Olof Nyg.ang.rds
An ammunition unit has a fuze which includes an electrical trajectory safety device for preventing arming of the ammunition unit within a trajectory safety distance. An arming igniter actuable by the electrical trajectory safety device activates a movable portion for execution of an instantaneous movement to move a bursting cap disposed in the movable portion into an arming position in register with the initiation detonator included in a detonation chain and actuable by an impact or a proximity fuze contact. The movable portion is lockable by a locking pin, which is actuable on a retardation of the ammunition unit caused by a first hit of the ammunition unit against a first object located within the trajectory safety distance. Upon actuation, the locking pin locks the movable portion to prevent it from executing the instantaneous movement, even if the first hit were to cause mechanical action on the electronics which effects actuation of the arming igniter. The ammunition unit, on a second hit, assumes a safe position such that the total bursting of the ammunition unit through the intermediary of the bursting cap is prevented.
93 Detonation safety mechanism US938079 1986-12-04 US4727809A 1988-03-01 Robert C. M. Watson
A safety device for use in the detonation of explosives, mines etc. Explosives are commonly detonated by a two stage operation, an explosive pellet is moved from a safe to an active position and then a hammer or electrical charge is fired to detonate the pellet. Failure of the second stage operation leaves the explosive in an unsafe condition, since the hammer or charge might fall as the fault is being investigated. The invention provides movement of the pellet from one safe position to another continuously and through an active position. If the hammer fails to fall as the pellet passes through the active position the device will assume a safe condition.
94 Detonator for rifle grenades or the like US818669 1986-01-14 US4676165A 1987-06-30 Tsvi J. Gordon; Sorek Shmuel; David Moseinco
A fuze of the type used in a rifle grenade assembly with a striker, a rotornd a rotor lock includes one or more improvements. One pertains to the striker to prevent it from reaching a detonator-striking forward position more than once. Once it advances to the forward position it is locked in it by a spring biased locking pin. Other improvements relate to the release of the rotor by the rotor lock. The rotor remains locked, i.e. in the disarmed state even after intentional launching. It is released to assume the armed state only when the launched assembly accelerates at a certain rate toward the target.

96 Fuze with bimetallic spring delay module US700993 1976-06-29 US4047484A 1977-09-13 Lewis C. Cole
A fuze containing a bimetallic spring delay module, which includes a bimelic Belleville spring and a pyrotechnic charge for heating the spring. The spring is capable of inverting by heat from the pyrotechnic charge and of reverting on cooling, whereby the spring provides a mechanical action by means of an element attached thereto, such as a firing pin, switch, an arming slider or rotor, etc.
97 Anti-recovery device disarming mechanism US85547069 1969-09-03 US3908553A 1975-09-30 BEACH EUGENE H
A mechanism for disarming an anti-recovery device for a weapon by electrically and mechanically interrupting the firing system of the weapon. The mechanism includes a combination lock which extends and retracts a cam. A detonator is moved by the cam into and out of alignment in an explosive train as the lock is operated. Movement of the cam also closes or breaks a firing circuit which includes an anti-recovery triggering system. When the cam is retracted by unlocking the combination lock, the detonator is non-aligned in the explosive train, and the firing circuit is interrupted, rendering the anti-recovery triggering system ineffective.
98 Velocity discriminating time mechanical ordnance fuze US3677186D 1969-10-01 US3677186A 1972-07-18 MUNACH ARNOLD S
A mechanical ordnance fuze having an arming slider held by a timer controlled lock and a catch rod. Axially aligned with the catch rod are a pair of centrifugally opened detents attached to a shaft rotated by a wind driven vane. When the vane is rotating sufficiently fast to open the detents, the catch rod, released by the timer, passes between the detents and clears the arming slider, thereby allowing the slider to arm when released by the lock. Otherwise the catch rod is blocked by the unopened detents and when the timer operates to unlock the slider, it is caught by the catch rod and the fuze remains unarmed.
99 Mine fuse safing system US3568601D 1968-07-26 US3568601A 1971-03-09 MORROW WARREN P
The regulator of a fuze timing clock includes an electrical switch, which utilizes the breathing action of a balance wheel hairspring and a single or double stator contact. The switch produces a series of timing pulses which are dependent upon the number of stator contacts used and the period of the breathing action of the hairspring. In a fuze, the pulses can operate a self-sterilization circuit which will place the fuze in an unarmed or nonfiring condition. In such a fuze, power is fed to the output section of the fuze only when there is a continuous series of sustaining pulses from the electrical switch. Cessation of these pulses causes the sterilization circuit to turn off the output section gate thus removing power from the output of the fuze.
