Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
77 words
A BLASTING COMPOSITION IN THE FORM OF A SOLID EMULSION CONSISTING ESSENTIALLY OF 100 PARTS BY WEIGHT OF AN AQUEOUS SOLUTION OF NITRIC ACID CONTAINING FROM ABOUT 30% TO ABOUT 80% BY WEIGHT OF NITRIC ACID, FROM ABOUT 300 TO ABOUT 550 PARTS BY WEIGHT OF AMMONIUM NITRATE, FROM ABOUT 20 TO ABOUT 80 PARTS BY WEIGHT OF AN INSENTIVE, IMMISCIBLE FUEL MATERIAL, AND FROM ABOUT 6 TO ABOUT 50 PARTS BY WEIGHT OF AN ACIDRESISTANT SURFACTANT.
Claim 2
Dependent Claim
77 words
A BLASTING COMPOSITION IN THE FORM OF A SOLID EMULSION CONSISTING ESSENTIALLY OF 100 PARTS BY WEIGHT OF AN AQUEOUS SOLUTION OF NITRIC ACID CONTAINING FROM ABOUT 30% TO ABOUT 80% BY WEIGHT OF NITRIC ACID, FROM ABOUT 300 TO ABOUT 550 PARTS BY WEIGHT OF AMMONIUM NITRATE, FROM ABOUT 20 TO ABOUT 80 PARTS BY WEIGHT OF AN INSENTIVE, IMMISCIBLE FUEL MATERIAL, AND FROM ABOUT 6 TO ABOUT 50 PARTS BY WEIGHT OF AN ACIDRESISTANT SURFACTANT.
Claim 3
Independent Claim
137 words
A METHOD OF PREPARING A BLASTING COMPOSITION COMPRISING THE STEPS OF BLENDING FROM ABOUT 20 PARTS TO ABOUT 80 PARTS BY WEIGHT OF INSENSITIVE, IMMISCIBLE CARBONACEOUS FUEL WITH FROM ABOUT 6 PARTS TO ABOUT 50 PARTS BY WEIGHT OF A ACID-RESISTANT SURFACTANT, MIXING FROM ABOUT 300 PARTS TO ABOUT 550 PARTS BY WEIGHT OF NITRATE SELECTED FROM THE GROUP CONSISTING OF AMMONIUM NITRATE AND ALKALI METAL NITRATES WITH SAID BLEND OF CARBONACEOUS FUEL AND ACID-RESISTANT SURFACTANT, ADDING 100 PARTS BY WEIGHT OF AN AQUEOUS SLUTION OF NITRIC ACID CONTAINING FROM ABOUT 30% TO ABOUT 80% BY WEIGHT OF NITRIC ACID TO SAID BLEND OF FUEL, SURFACTANT AND NITRATE, AGITATING SAID MIXTURE TO FORM AN EMULSION, HEATING SAID EMULSION TO A TEMPERATURE LESS THAN ABOUT 150*F. TO FORM A MELT AND ALLOWING SAID EMULSION TO COOL AND SOLIDIFY.
