Process of making linear shaped charge explosive devices

Claim 1

A PROCESS FOR PRODUCING A LINEAR SHAPED EXPLOSIVE CHARGE UNIT WITH COMPRISES: PROVIDING A LENGTH OF ELONGATED GENERALLY TUBULAR CASING HAVING A LONGITUDINALLY EXTENSING, DEFORMABLE WALL PORTION BEING CAPABLE OF TAKING A PERMANETN SET; FORCING INWARDLY SAID LONGTIUDINALLY EXTENDING DEFORMABLE WALL PORTION OF SAID CASING TO PRODUCE A LONGITUDINAL GROOVE IN SAID CASING THEREBY REDUCING THE INTERNAL VOLUME OF SAID CASING; THEREAFTER FILLING SAID GROOVED CASING WITH PARTICULATE HIGH EXPLOSIVE MATERIAL; AND FORCING INWARDLY THE LONGITUDINALLY EXTENDING, DEFORMABLE WALL PORTION OF SAID EXPLOSIVE FILLED CASING ALONG SAID LONGITUDINAL GROOVE TO PRODUCE A LONGITUDINAL GROOVE OF INCREASED DEPTH, THEREBY FORMING A RE-ENTRATN SHAPED CHARGE CAVITY LINER FROM SAID DEFORMABLE PORTION OF SAID CASING, COMPRESSING SAID PARTICULATE HIGH EXPLOSIVE MATERIAL BETWEEN THE INNER WALLS OF SAID CASING AND SHAPING SAID HIGH EXPLOSIVE MATERIAL TO CONFORM TO SAID INNER WALLS, TO PRODUCE A LINEAR SHAPED CHARGE HAVING A LOWER EXPLOSIVE WEIGHT PER UNIT LENGTH AND A DEEPER LONGITUDINAL GROOVE COMPARED TO A LINEAR SHAPED CHARGE PRODUCED AS DESCRIBED IN THE FOREGOING STEPS WITH THE EXCEPTION THAT THE CASING IS NOT PREGROOVED TO REDUCE THE INTERNAL VOLUME THEREOF BEFORE BEING FILLED WITH PARTICULATE EXPLOSIVE MATERIAL.
