Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
97 words
THE METHOD OF CONDITIONING GRANULAR MATERIAL WHICH COMPRISES MULLING THE GRANULAR MATERIAL IN A MILL, FEEDING A UNIFORM SAMPLE OF THE GRNNULAR MATERIAL TO A SEPARATOR SCREEN, TRAVERSING THE UNIFORM SAMPLE ACROSS THE SEPARATOR SCREEN TO SEPARATE A PORTION THEREOF FROM THE BALANCE OF THE SAMPLE THE RELATIVE WIEIGHT OF WHICH PORTION IS REPRESENTATIVE OF THE MOLDABILITY OF THE GRANULAR MATERIAL, DISCARDING SAID BALANCE OF THE SAMPLE, AND CONTROLLING THE METERING OF AN ADDITIVE INOT THE MILL ONLY IN ACCORDANCE WITH THE RELATIVE WEIGHT OF THE PORITON OF THE SAMPLE SEPARATED FOROM THE BALANCE OF THE SAMPLE.

Claim 3
Dependent Claim
131 words
APPARATUS FOR CONDITIONING GRANULAR MATERIAL COMPRISING A MILL FOR MULLING GRANULAR MATERIAL TO FORM COHESIVE MASSES THEREIN, MEANS FOR METERING AN ADDITIVE INTO THE MILL TO VARY THE MOLDABILITY OF THE GRANULAR MATERIAL IN THE MILL AS MEASURED BY THE COHESIVENESS THEREOF, MOVABLE MEANS FREE OF EXTERNAL FRICTION LOCATED ADJACENT SAID MILL, MEANS RESPONSIVE TO THE POSITION OF SAID MOVABLE MEANS FOR CONTROLLING THE MEANS FOR METERING THE ADDITIVE TO THE MILL, MEANS POSITIONED RELATIVE TO SAID MILL FOR RRECIVING A SAMPLE OF GRANULAR MATERIAL THEREFROM AND FOR SEPARATING A PORTION OF THE SAMPLE THEREFROM IN ACCORDANCE WITH ITS COHESIVENESS, MEANS FOR FEEDING SAID SEPARATED PORTION OF THE SAMPLE TO SAID MOVABLE MEANS FOR POSITIONING SAID MOVABLE MEANS IN ACCORDANCE WITH THE COHESIVENESS AND THEREFORE THE MOLDABILITY OF SAID GRANULAR MATERIAL.
