Radioisotope method for measuring the weight of the contents of assembled items

Claim 1

IN A METHOD OF MANUFACTURING PRIMERS, SUCH THAT THE QUANTITY OF PRIMER COMPOSITION THEREIN IS KEPT UNIFORM FROM PRIMER TO PRIMER, THE STEPS COMPRISING: MIXING A WET PRIMER COMPOSITION WITH A RADIOACTIVE SOURCE TO ACHIEVE HOMOGENEITY AND UNIFORM RADIATION THEREFROM, MAINTAINING THE RESULTING HOMOGENEOUS MIXTURE IN A WET CONDITION, LOADING SAID HOMOGENOUS MIXTURE INTO PRIMER CUPS, COVERING SAID HOMOGENEOUS MIXTURE WITH AN ANVIL HAVING A HOLE THEREIN, PASSING SAID LOADED PRIMERS UNDER A RADIOACTIVELY SENSITIVE DEVICE AT A PRESELECTED DISTANCE THEREFROM, MEASURING THE RADIATION EMITTED FROM SAID MIXTURE, SAID RADIATION BEING DIRECTLY PROPORTIONAL TO THE AMOUNT OF MIXTURE IN SAID PRIMER CUP, TRANSLATING SAID RADIATION INTO A POTENTIAL PROPORTIOANAL THERETO, AND APPLYING SAID POTENTIAL TO MEANS WHEREBY ONLY THOSE PRIMERS CAUSING A POTENTIAL WITHIN A GIVEN RANGE ARE SELECTED AND PRIMERS CAUSING A POTENTIALY OUTSIDE OF SAID GIVEN RANGE ARE REJECTED.
