专利汇可以提供Ignition circuit for projectile fuses专利检索,专利查询,专利分析的服务。并且A projectile with an electrically ignitable fuse is provided with a control circuit in which piezo electric cells are provided which develop a potential upon acceleration of the projectile and then develop a reverse potential upon relaxing of the acceleration on the projectile when it emerges from the firing weapon. The piezo electric cells are serially arranged and connected thereacross is a pair of condensors, the juncture of which is fastened to the juncture of the cells with one capacitor charging during the acceleration period of the projectile and the other charging during the relaxing period. A resistor connected across the capacitors provides for reversing of the charge on the one capacitor and which reversing triggers a control circuit. The control circuit releases the charge from a third capacitor which is charged by one of the cells during the relaxing period thereby to ignite the fuse. An impact control source of voltage is also provided for igniting the fuse upon impact of the projectile.,下面是Ignition circuit for projectile fuses专利的具体信息内容。

1. An igniting system for an electrically operated projectile fuse comprising; a voltage source and circuit means connecting the voltage source to said fuse, said voltage source developing voltage pulses upon acceleration of the projectile containing the fuse, said circuit means comprising a time controlled charge reversing circuit connected to said source, control means connected to said charge reversing circuit and actuated thereby at the expiration of the time period pertaining to said reversing circuit, and means connecting said control means to said fuse for igniting the fuse by said control means upon actuation thereof, said voltage source comprising a pair of piezo electric cells in serial relation with a common center terminal, said charge reversing circuit comprising a capacitor connected across each cell and a resistor connected in parallel with said capacitors, and diode means interposed between said cells and the respective capacitors and so poled that one cell charges its capacitor during the acceleration period of the projectile while the other cell charges its capacitor following the acceleration period of the projectile.
2. An igniting system according to claim 1 in which said circuit means includes a further capacitor adapted to be charged by said one cell at the end of said acceleration period of the projectile and connected to said fuse, said control means when actuated releasing the charge on said further capacitor to said fuse to ignite the fuse.
3. An igniting system according to claim 1 which includes a zener diode connected in parallel with the capacitor pertaining to said one cell to limit the voltage rise thereof during the acceleration period of said projectile to a value less than that supplied to the capacitor pertaining to said other cell following the acceleration period of said projectile.
4. An igniting system according to claim 3 which includes a diode in series with said zener diode and poled to prevent discharge of the capacitor pertaining to said one cell following the acceleration period of said projectile.
5. An igniting system according to claim 1 which includes an impact sensitive voltage source connected to said fuse and operable to supply igniting voltage to said fuse upon impact of said projectile.
