    摘要: In fuse elements of layered structure with long delay times, misfires, occur, above all, if aggravating secondary conditions prevail (such as, for example, high projectile rotation and/or temperature stresses and shock stresses). The safe progression of the reaction through the element is enhanced by providing that, as seen in the propagation direction of the reaction, the central zone of a charge igniting a delay charge projects into a central region of the delay charge. An additional improvement can be achieved by interposing between the ignition charge and the delay section, one or several relay charges and by making the choice of the charge components so that the discontinuities of the characteristic values (especially of the reaction rate) become more even and thus smaller, or by utilizing an ignition charge having a particularly low reaction rate.

    摘要: One fuse head has an insulating pole body with electrically conducting longitudinal strips, an incandescence bridge arranged on the pole body between the strips and connecting wires. The glow bridge and the connecting wires each being connected via soldered joints to the longitudinal strips. The fuse head also has at least one priming explosive and an external varnish finish coating covering the at least one priming explosive. To improve adherence, to facilitate the manufacturing process, to reduce the size of the solder joints, and to reduce the weight distribution of the priming explosive, it is proposed to arrange on the pole body, perpendicular to the pole body axis, grooves which are filled with priming explosive. Another fuse head has a basic module with electrically conducting pole supports running through it, the ends of the supports being connected on the ignition side via an incandescence bridge. It is proposed to arrange on the basic module at least one groove perpendicular to a longitudinal axis of the basic module, said at least one groove being filled with priming explosive.

    摘要: Pyrotechnic delay compositions with delays in the seconds range are based on a pyrotechnic delay mixture of powdered metallic tungsten, barium chromate an potassium perchlorate, and additionally contain either barium hexafluorosilicate or calcium fluoride pyrogenic silica. The additives cause these compositions to burn completely even under severe environmental conditions, such as very fast rotation, vibration, impact, shock, and, at the same time, extremely low below-freezing temperatures. The effect of the barium hexafluorosilicate is still further improved if the delay compositions additionally contain pyrogenic silica.
