摘要： A plurality of electric blasting caps are fired through the ignition system which includes a transformer (19) having a primary winding (17) and a secondary winding (21). The secondary winding (21) of the transformer (19) is connected to the resistive elements (53) of the blasting caps (55) through a blasting circuit which is electromagnetically coupled to the resistive elements (53) of the blasting caps (55) via a small toroid transformer. A D.C. voltage is stored on a storage capacitor (3) which has one end connected to the center point (15) of the primary winding (17). The other ends of each half of the primary winding (17) are connected through a driver circuit (29) to ground. Each driver circuit (29) is enabled by a flip-flop (35) at predetermined intervals, whereby the storage capacitor (3) will discharge through the appropriate half of the primary, to thereby produce a pulse train at the output of the secondary. The pulse train provides the ignition power for igniting the electric blasting caps.

摘要： A primer for use in detonating an explosive charge comprises a rigid explosive-filled container fitted with an elongate neck. A bore in the neck which extends into the explosive of the primer provides accommodation for a firing means such as a detonator or fusecord. The primer is attached to a shock tube/wiring of a detonator or a fusecord by means of a fastening means located at the end of the neck remote from the container and which is capable of supporting the entire weight of the primer.
In a preferred embodiment, the container is spherical and the neck is a plastics mouldlng with protrusions around which the fusecord/shock tube/ wiring can be looped and gripping means to hold it there.
The primers of the invention are particularly safe and efficacious in use.摘要翻译： 用于引爆炸药的底漆包括装有细长颈部的刚性爆炸性填充容器。 延伸入底漆爆炸物的脖颈中的钻孔提供了用于诸如雷管或风口等击发装置的容纳物。 底漆通过位于远离容器的颈部末端处的紧固装置附接到雷管或风口的冲击管/布线，其能够支撑底漆的整个重量。 在一个优选实施例中，容器是球形的，并且颈部是具有突出部分的塑料模制件，可以在其周围形成软管/冲击管/布线并且夹持装置将其保持在那里。 本发明的引物在使用中特别安全和有效。

摘要： A positive displacement explosive base dosing pump is provided with a drive motor 14 and has an outlet 22 connected via a flexible hose 24 to a lance 70. The lance 70 has a mixing device 72 therein and a reciprocable positive displacement gassing solution dosing pump has an outlet connected via a flexible conduit 54 to the lance and feeding into the lance upstream of the mixing device 72. The invention involves using the base dosing pump 12 to pump explosive base from a supply 78 along the hose 24 to the lance 70 while the gassing solution dosing pump 16 simultaneously pumps gassing solution from a supply 56 along the flexible conduit 54. The conduit 54 leads the solution into the lance 70 upstream of the mixing device 72 whereby the explosive base is mixed with the solution, so that a mixture issues from the lance 70 which becomes sensitized after reaction has taken place between the base and solution.

摘要： A connector (10) for joining two lengths of low intensity shock tube (34), eg NONEL shock tube,has a body provided with three passages (20,22) extending therethrough alongside one another,the passages opening out into opposite faces (16) of the body. In the preferred connector (10) one of the passages (20) comprises two inwardly tapering portions (24), which advantageously have longitudinally spaced circumferentially extending ribs (30) standing proud of their surfaces to grip the shock tube (34). Conveniently the body is a moulding of synthetic plastics material.

摘要： A packaged booster charge is provided which is sensitive to initiation by blasting cap yet which contains no self-explosive ingredient. The composition of the booster comprises a low melting point nitrate salt or salt mixture having dissolved or finely dispersed therein an acetylenic substance and void containing material. The booster is safe and economic to manufacture and sufficiently powerful to initiate insensitive blasting agents.
