Claim 1

A PROPELLANT EXPLOSIVE COMPOSITION HAVING A CALORIFIC VALUE OF SUBSTANTIALLY FROM 650-850 CALORIES PER GRAMME, WATER GASEOUS, AND OF SUPPRESSED FLASH AND EROSIVE CHARACTERISTIC FOR USE WITH LARGE GUNS, COMPRISING SUBSTANTIALLY 50-65% NITROGUANIDINE, THE PARTICLES OF WHICH HAVE A SPECIFIC SURFACE OF AT LEAST 9,000 SQ. CM. PER C. C. DISPERSED IN 16-23% NITROECLLULOSE GELATINISED BY 0.8 TO 1.5 TIMES ITS WEIGHT OF A LIQUID EXPLOSIVE NITRIC ESTER, AND DIETHYL DIPHENYL UREA IN THE FORM OF A FINELY DIVIDED, HOMOGENEOUSLY DISTRIBUTED DOUBLE COMPOUND WITH NITROGUANIDINE.

Claim 3

A METHOD FOR THE MANUFACTURE OF PROPELLANT EXPLOSIVE COMPOSITIONS HAVING A CALORIFIC VALUE OF SUBSTANTIALLY 650-850 CALORIES PER GRAMME WATER GASEOUS AND OF SUPPRESSED FLASH AND EROSIVE CHARACTERISTICS FOR USE WITH LARGE GUNS, COMPRISING FIRST THOROUGHLY DISPERSING 50-65% NITROGUANIDINE, THE PARTICLES OF WHICH HAVE A SPECIFIC SURFACE OF AT LEAST 9,000 SQUARE CENTIMETERS PER C. C. IN 16-23% NITROCELLULOSE GELATINISED WITH 0.8-1.5 TIMES ITS WEIGHT OF A LIQUID EXPLOSIVE NITRIC ESTER, AND THEREAFTER STABILIZING THE COMPOSITION WITH DIETHYL DIPHENYL UREA ADDED ONLY AFTER MIXING THE NITROGUANIDINE AND NITROCELLULOSE-LIQUID EXPLOSIVE NITRIC ESTER THOROUGHLY FOR SUBSTANTIALLY FIFTEEN TO THIRTY MINUTES, THE WITHHOLDING OF THE ADDITION OF THE DIETHYL DIPHENYL UREA RESULTING IN HOMOGENEOUS DISTRIBUTION, THROUGHOUT THE COMPOSITION, OF A FINELY DIVIDED DOUBLE COMPOUND FORMED BY INTERACTION OF THE NITROGUANIDINE AND THE DIETHYL DIPHENYL UREA.

Claim 4

A METHOD FOR THE MANUFACTURE OF PROPELLANT EXPLOSIVE COMPOSITIONS HAVING A CALORIFIC VALUE OF SUBSTANTIALLY 650-850 CALORIES PER GRAMME WATER GASEOUS AND OF SUPPRESSED FLASH AND EROSIVE CHARACTERISTICS FOR USE WITH LARGE GUNS, COMPRISING FIRST THOROUGHLY DISPERSING 50-65% NITROGUANIDINE, THE PARTICLES OF WHICH HAVE A SPECIFIC SURFACE OF AT LEAST 9,000 SQUARE CENTIMETERS PER C. C. IN 16-23% NITROCELLULOSE GELATINISED WITH 0.8-1.5 TIMES ITS WEIGHT OF A LIQUID EXPLOSIVE NITRIC ESTER, AND THEREAFTER STABILIZING THE COMPOSITION WITH DIETHYL DIPHENYL UREA ADDED ONLY AFTER MIXING THE NITROGUANIDINE AND NITROCELLULOSE-LIQUID EXPLOSIVE NITRIC ESTER THOROUGHLY FOR SUBSTANTIALLY FIFTEEN TO THIRTY MINUTES, THE WITHHOLDING OF THE ADDITION OF THE DIETHYL DIPHENYL UREA RESULTING IN HOMOGENEOUS DISTRIBUTION, THROUGHOUT THE COMPOSITION, OF A FINELY DIVIDED DOUBLE COMPOUND FORMED BY INTERACTION OF THE NITROGUANIDINE AND THE DIETHYL DIPHENYL UREA.
