| abstract | 1. An apparatus for burning through explosive containing cases and for melting out the enclosed explosive comprising a metal cylinder having a bore along the longitudinal axis thereof, said cylinder being externally-threaded at each of its ends; FIRST COMBUSTIBLE SOLID PROPELLANT MIXTURE WHICH BURNS TO PRODUCE A RELATIVELY HIGH-TEMPERATURE GASEOUS PRODUCT POSITIONED IN SAID BORE AT ONE END THEREOF; A SECOND COMBUSTIBLE SOLID PROPELLANT MIXTURE WHICH BURNS TO PRODUCE A RELATIVELY LOW-TEMPERATURE GASEOUS PRODUCT POSITIONED IN SAID BORE AT THE OTHER END THEREOF; MEANS CLOSING SAID ONE END OF SAID BORE INCLUDING A LABYRINTHIC METAL DISC AND AN INTERNALLY THREADED CAP ADAPTED FOR THREADED ENGAGEMENT WITH SAID CYLINDER, SAID CAP HAVING AN ORIFICE THEREIN AND AN INTERNAL WALL TAPERING OUTWARDLY THEREFROM AND DEFINING A FRUSTO-CONICAL-SHAPED CAVITY THEREWITHIN, SAID WALL ABUTTING SAID DISC FOR FIRMLY FIXING SAID DISC OVER SAID BORE; MEANS CLOSING SAID OTHER END OF SAID BORE INCLUDING A METAL SEALING DISC IN SAID BORE, AN INTERNALLY-THREADED CAP IN THREADED ENGAGEMENT WITH SAID CYLINDER AND A SPACER RING MOUNTED BETWEEN SAID SEALING DISC AND SAID CAP SO THAT SAID SPACER RING AND SAID SEALING DISC URGE SAID SOLID PROPELLANT MIXTURES AGAINST SAID METAL DISC AT SAID ONE END OF SAID BORE, SAID LAST MENTIONED CAP HAVING AN APERTURE THEREIN; AND IGNITION MEANS FOR IGNITING THE SOLID PROPELLANT MIXTURES INCLUDING A HEAT SENSITIVE IGNITER MATERIAL IN CONTACTING RELATIONSHIP WITH SAID FIRST SOLID PROPELLANT MIXTURE, AN INITIATOR FOR FIRING SAID IGNITER FOR FIRING SAID IGNITER MATERIAL AND MEANS CARRIED BY SAID LAST NAMED CAP IN SEALED ENGAGEMENT WITH THE WALL OF SAID APERTURE IN SAID LAST NAMED CAP FOR ACTUATING SAID INITIATOR; WHEREBY THE SOLID PROPELLANT MIXTURES ARE IGNITED IN SUCCESSIVE ORDER AND THE GASES DEVELOPED FROM THE BURNING THEREOF PASS THROUGH A LABYRINTH PATH IN THE FIRST-MENTIONED DISC, BUILD UP PRESSURE WITHIN THE FRUSTO-CONICAL CAVITY OF THE FIRSTMENTIONED CAP AND ARE DISCHARGED FROM THE ORIFICE THEREIN AS A HIGH-VELOCITY, GASEOUS JET, FIRST HAVING A RELATIVELY HIGH TEMPERATURE AND THEN A RELATIVELY LOW TEMPERATURE. |
