    摘要： A detonator for a land mine containing electric circuit means for controlling and effecting the ignition of a detonator pellet, a driving mechanism controlled by said electric circuit for delaying the ignition of said pellet for a predetermined period of time, and a movable contact device subject to a change of position away from a gravity induced initial position for closing a portion of said electric circuit means. A slidable member in the housing of said detonator when moved in one direction actuates a switch member which starts the operation of said driving mechanism and at the same time moves another movable contact member into a position between two spaced fixed contacts, both of which are connected with said electric circuit means. Upon applying an external force to said slidable member, the same is moved an additional amount and the movable contact member is brought into engagement with one of said fixed contacts, thereby closing said electric circuit means for effecting the ignition.

    摘要： 1. A tail fuze comprising in combination: a body having a nose end and a tail end, said body being adapted to fit into a fuze well; a cover at said nose end; a cap on said tail end; an air arming reduction gear cluster disposed in said body adjacent said tail end for transmitting a predetermined rate of angular rotation; a main setting shaft disposed in said body substantially parallel to the axis of said body and along a major portion thereof; a primary safety cam rotatably disposed in said body adjacent said tail end and coupled to said gear cluster and rotatable therewith, said safety cam engaging the end of said shaft disposed nearest said tail end to maintain said shaft in a substantially fixed position, said safety cam adapted to longitudinally displace said shaft from said fixed position to a first position upon rotation of said gear cluster for a predetermined time interval, said shaft at said first position being free so as to be longitudinally displaced to a second position when said fuze body impacts on said nose end; a preset timer disposed axially of said fuze body and intermediate said nose and tail ends; gear means operably connecting said timer to said shaft, said gear means locking said timer against movement during said fixed and first positions and releasing said timer at said second position; a rotatable timing cam coupled with said timer and rotatable upon rotational movement of said timer, said timing cam having a slot in its periphery; a stop mounted on the nose end of said main setting shaft and disposed within said body; a spring-biased stab firing pin axially disposed adjacent said nose end; a spring-biased rotatable release lever having bifurcated first and second arms, the end of the first arm contacting the periphery of said timing cam; a spring-biased rotor mounted for rotation adjacent said nose end; a detonator in said rotor, the second arm of said lever blocking axial movement of said firing pin towards said rotor, said stop engaging said rotor during said fixed and first positions to lock said detonator out-of-line with said firing pin, said stop moving from engagement with said rotor at said second position so that said detonator is aligned with said firing pin, said stop also locking and unlocking said timing cam during said first and second positions, respectively, said timing cam after being unlocked rotating until the end of said first arm enters said slot, said second arm then being moved by the spring-bias acting on said lever so as to unblock said firing pin, said firing pin thereby being free to strike said detonator and initiate detonation of said fuze; a rotatable tamper release cam positioned in said nose end, said release cam being biased from locking contact with said stop, on end of said release cam being locked against rotative movement by said stop during said fixed and first positions and unlocked for rotation at said second position, the other end of said release cam being serrated so as to firmly grip the wall of said fuze well at said second position; and means on said release cam to contact the end of said second arm; said tamper release cam and said means Thereon being so constructed and arranged that if subsequent to impact said body is rotated in a direction which would remove said fuze body from said fuze well, said second arm will be moved out of blocking position with said firing pin so that said firing pin can strike said detonator and initiate detonation of said fuze.

    摘要： The present invention is directed to a system and a method for accurately locating a penetrating-type weapon within a shelter for detonation at a desired target site. The method includes reliably and accurately detecting thin layers of a shelter by use of a weapon frequency induced by a vibration in a portion of the weapon. The weapon frequency is detected and at least one harmonic frequency of the weapon frequency is analyzed to determine whether a deceleration threshold event has occurred. In one embodiment, the harmonic frequency may be compared to a target frequency which is associated with the deceleration of the weapon during penetration of a layer of media. In another embodiment multiple weapon frequencies may be detected, analyzed, or compared to detect the penetration of a layer of media.

    摘要： An ignition device for mines, in particular training mines. The device includes a percussion bolt which is mechanically held in an inoperative position and is loaded by the action of a coil spring so that when released it is propelled axially towards a pyrophoric ignition charge to initiate an ignition chain.The ignition device is of simple and inexpensive construction and can be mechanically released by forces acting in a variety of directions. The device includes a cylindrical housing in which a percussion bolt and actuating lever are mounted one behind the other in axial alignment. A plurality of cup-shaped members, preferably a pair, are mounted in the housing so as to surround at least a portion of the actuating lever and percussion bolt. Upon actuation of the lever by applying a force thereto in a predetermined direction the cup-shaped members are spread apart against a biasing force to release the percussion bolt in the firing direction.
