    • A low energy fuse, comprising a plastic tube with a channel, the channel containing a reactive material able upon ignition to sustain a shock wave within the channel, the tube comprising at least two layers of plastic materials, a first plastic layer closer to the channel and a second plastic layer outside the first layer, at least the second layer containing a major amount of draw orientable polymer resin. The polymer in the second layer is axially oriented to an orientation degree (as defined) of more than 25 % and less than 90 % and that the polymer of the first layer has an axial orientation degree not exceeding 10 % orientation degree units more than that of the second layer. The tube can be manufactured by a) forming, by extrusion of the first layer plastic, the first layer in the form of a tube, b) introducing the reactive material in the tube channel, c) limiting stretching of the first layer to give a low degree of orientation, not exceeding 10 % (as defined), d) forming, by extrusion of the second layer plastic, the second layer around the first tube, while the first layer have said low degree of orientation, and e) cold-stretching the first and second layers together.
    • 一种低能量熔断器,包括具有通道的塑料管,所述通道包含能够点燃以在所述通道内维持冲击波的反应性材料,所述管包括至少两层塑料材料,更接近所述通道的第一塑料层 以及在第一层之外的第二塑料层,至少第二层含有大量可拉伸取向的聚合物树脂。 第二层中的聚合物被轴向定向为大于25%且小于90%的取向度(定义),并且第一层的聚合物的轴向取向度不超过10%的取向度单位 的第二层。 管可以通过以下方式制造:a)通过挤出第一层塑料形成管形式的第一层,b)将反应性材料引入管道中,c)限制第一层的拉伸,得到 低定向度,不超过10%(如定义),d)通过第二层塑料挤出形成第二层围绕第一管,而第一层具有低取向度,以及e) 将第一和第二层拉伸在一起。

    • A rock-breaking cartridge (10) includes a casing (16) of deformable material that forms an internal cavity (22) and a tapered part (82). A seal (90) extends around the outside of the tapered part (82) and a piston (92) inside the cavity (22) butts against the inside of the tapered part (82) to seal against the inside of the casing (16). A charge (46) is provided inside the cavity (22) on the side of the piston (92) that is opposite from a narrow end of the tapered part (82) and when the charge (46) is ignited, it causes the piston (92) to slide towards the narrow end and to force the tapered part (82) and seal (90) to expand. The expansion causes the seal (90) to seal against the inside of a hole in which the cartridge (10) has been placed and the seal (90), tapered part (82) and piston (92) form a sturdy plug to contain gasses generated by detonation of the charge (46).

    • An explosives container comprising a flexible inner bag within a flexible outer bag, the outer bag comprising a first end and a second end and a booster compartment located on an external surface of the outer bag, adjacent the second end. An explosive composition can be located within the inner bag and, in use, the booster compartment contains an explosive booster and serves to maintain the explosive booster in close contact with the explosives composition. The explosives container further comprises an elongate sheath extending substantially between the first end and the second end of the outer bag and serving to house and protect a detonator cord from damage or dislodgement.
    • 一种爆炸物容器,其包括在柔性外袋内的柔性内袋,所述外袋包括第一端和第二端以及位于所述外袋的外表面上的与所述第二端相邻的增强隔间。 爆炸物组合物可以位于内袋内,并且在使用中,增压室包含爆炸助力器并用于使爆炸助力器与炸药组合物紧密接触。 爆炸物容器还包括基本上在外袋的第一端和第二端之间延伸的细长鞘,并且用于容纳和保护雷管不被损坏或移动。
