摘要： A mechanical igniter for a gas generator has a weight, a latch lever and a firing pin, which are provided in a casing as movable elements to fire a percussion cap attached to the gas generator in response to acceleration. The mechanical igniter further has a restraint member movably supported in the casing as a safety catch for making the movable elements immovable. The casing and the restraint member are respectively formed with cam surfaces which cooperate with each other to rotate the restraint member about its own axis so that the restraint member is selectively set in a restraint position and a release position. The restraint member has a rotary control portion that is concealed in the casing and has a portion that is engageable by a rotary tightening tool, such as used in an ordinary bolt tightening operation or the like. The restraint member is rotated by engaging the rotary tightening tool with the rotary control portion of the restraint member and turning the tool. As a result of the rotation, the restraint member is displaced from the restraint position to the release position and set in the latter position by the cooperation of the cam surfaces. Thus, the movable elements are released from the immovable state, thereby allowing the igniter to fire the percussion cap in response to acceleration.

摘要： The invention relates to an impact fuse (2) having fore-bore safety for a projectile (1), comprising a percussion needle (3) stationary on the fuse and an impact body (4) containing a percussion cap (5) and supported slidingly in the direction of flight, as well as a race for a blocking ball (23) between the impact body and the inner wall of the projectile casing. Which, upon premature impact on an obstacle, is jammed in its race (22) between a shoulder (18, 19, 20) on the inner wall of the casing and a ramp (17) of a groove (14, 15, 16) on the impact body (4), thereby preventing detonation. In order to allow for adjustment of predefined distances for the fore-bore safety, the invention proposes giving the race (22) for the blocking ball (23) a stepped design so that the blocking ball (23) can be jammed at several places within the fuse (2) between shoulders (18, 19, 20) and ramps (17) of different grooves (14, 15, 16).

摘要： A backup mechanism for a fuze includes a plate having a slot therein which is freed up during the arming of the firing pin screw. A weight link having a pair of legs spaced along the slot is mounted for movement in the slot. A trip link is pivotally mounted to the plate and has a first leg for frictional engagement against the side of the first weight link leg. The second leg of the trip link is biased for rotation by a leaf spring. Another leaf spring engages against the second leg of the weight link for urging it in a movement direction along the slot. Friction between the first legs of the trip and weight links and/or the upward pull force of the ribbon hold the weight link in an initial position after fuze arming. When exposed to inertia, and/or the absence of upward ribbon pull force the weight link moves. This causes disengagement between its first leg and the first leg of the trip link. The spring rotates the strip link so that its first leg now pushes the weight link along the slot. The further leaf spring engaged against the second link of the weight link also pushes the weight link along the slot. A pin connected to the weight link is engaged with the weight of a standard fuze to enhance the pushing force on the weight.

摘要： 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.

摘要： An improved construction for a percussion fuse. The fuse function has a firing pin rigidly mounted in an ignition head an adapted to coact with a percussion cap mounted in an impact member. This impact member is securedly maintained in a first position by means of at least one blocking sphere which is partially mounted in an annular groove of the impact member and partially mounted in a bore of the cylindrical forward portion of the percussion fuse body. A movable inertial sphere is disposed in a chamber between the impact member and the ignition head. In order to improve the fail-safety there is mounted in this chamber a housing between the impact member and ignition head which is coaxially movable with respect to the firing pin. When the projectile is accelerated forwardly the housing moves against the impact member and the movable inertial sphere is clamped between the impact member and housing to thereby prevent a further relative motion between firing pin and percussion cap and to thereby prevent detonation of the percussion cap. During normal deceleration prior to target impact, the housing moves back from the impact member and allows the inertial sphere to roll into the annular chamber of the housing. This allows the impact member to move forward and thereby allows the percussion cap to impact the firing pin when the projectile impacts the target.

摘要翻译： 改进的打击乐保险丝结构。 保险丝功能具有刚性地安装在点火头中的撞针，其适于与安装在冲击构件中的冲击头共同作用。 该冲击构件通过至少一个阻挡球固定地保持在第一位置，该阻挡球部分地安装在冲击构件的环形槽中并且部分地安装在冲击保险丝体的圆柱形前部的孔中。 可动惯性球设置在冲击构件和点火头之间的室中。 为了提高故障安全性，在该室中安装有冲击构件和点火头之间的壳体，该壳体可相对于击发销同轴地移动。 当弹丸向前加速时，壳体抵靠冲击构件移动，并且可动惯性球被夹紧在冲击构件和壳体之间，从而防止撞针与冲击盖之间进一步的相对运动，从而防止冲击盖的爆震。 在目标冲击之前的正常减速期间，壳体从冲击构件移回，并允许惯性球滚动到壳体的环形室中。 这使得冲击构件向前移动，从而当弹丸撞击目标时，允许冲击帽撞击撞针。

摘要： The sensor includes a linearly movable mass including two sections and spring means urging one of the sections into operative engagement with means including an actuating element. The sensor also includes means releasably securing the two sections together and means releasing the securing means when the two sections have moved a predetermined distance against the urging of the spring. The two sections may be rollers of a rolamite unit. A flexible band extends around a portion of the two rollers. One example of a use for such a sensor is in an air bag safety restraint system.

摘要： A fuze for a spin-stabilized artillery projectile comprises a body includ: an ogive member containing point-detonating firing means, selectable for super-quick or delay firing; and a base member containing an inertial delay fuze operable by either direct or graze impact, a combustible fuse loop surrounding the inertial delay fuze and exposed to the point-detonating firing means, and a firing train coupling the inertial delay fuze and the fuse loop to a booster charge for initiating the main explosive charge of the projectile. The inertial delay fuze may comprise a cylindrical housing including a rear wall, an outer cylindrical wall and a front wall including a rearward tubular extension forming an annular chamber, a rearwardly-biased firing pin slidable in the tubular extension, a rearwardly-biased, annular, locking member slidable in the annular recess from a rear position, wherein it engages a series of detent balls which hold the firing pin in safe position, to a forward, firing pin-releasing position, a detonator positioned to be fired by the firing pin, and a series of spherical inertial weights which engage inclined cam surfaces on the locking member to force the latter forwardly on graze impact with a target.
