Abstract

610,106. Blasting-cartridges. CENTRE D'ETUDES M.B.A. (MECANIQUE, BALISTIQUE, ARMAMENT.). March 23, 1946, Nos. 9037 and 9038. Convention dates, Feb. 6, 1945, and Dec. 27, 1945. [Class 9 (i)] A blasting-cartridge based on the " hollowcharge " principle has a light cylindrical casing 1 closed at the rear by a plug 2 having its forward face 5 substantially conoidal, the centre part 4 being rounded to accommodate a priming charge 7, the forward face 8 of which is in contact with an explosive charge 10 so hollowed out that it has approximately uniform thickness in the direction of the axis of the casing. In addition a firing device is placed at the rear of the casing. Attached to the forward end of the casing 1 is an extension piece 11 having a bracket 12 for attaching the device to the object 13 to be drilled, the said extension 11 being of such a length that the distance of the charge 10 from the object 13 does not exceed 1.5 times the diameter of the charge 10. In use a combined detonator and fuze 15 is inserted in an axial hole in the plug 2 to contact the priming charge 7. On firing, the shape of the charges tends to focus the detonation wave along the axis of the casing 1 towards the object 13. To increase this focussing effect a funnelshaped member 18 may be inserted in the extension 11 with its nozzle end extending into a small hole 19 previously bored in the object 13. Modifications in the number and shape of the successive priming and explosive charges may be made. Recesses may also be provided in an intermediate priming charge to enhance the focussing effect. When a plurality of priming charges are used they are so chosen that the velocity of detonation of the several charges progressively decreases from rear to front of the device.
