Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
139 words
AN APPARATUS FOR DETECTING MATERIAL AND RATE OF FLOW OF SAID MATERIAL COMPRISING, A NEUTRON EMITTER ADAPTED TO BE POSITIONED ADJACENT SAID MATERIAL THEREBY ACTIVATING ELEMENTS IN SAID MATERIAL AND CAUSING SAID ELEMENTS TO BECOME RADIOACTIVE, A FIRST DIRECTIONAL SHIELDING MEANS POSITIONED ADJACENT SAID EMITTER CONTROLLING THE DIRECTION OF EMISSION FROM SAID EMITTER, A FIRST AND SECOND DETECTOR MEANS POSITIONED ON ONE SIDE OF SAID FIRST SHIELD MEANS REMOTE FROM SAID EMITTER FOR DETECTING THE RADIOACTIVE ELEMENTS IN SAID MATERIAL, A SECOND DIRECTIONAL SHIELDING MEANS POSITIONED BETWEEN SAID FIRST AND SECOND DETECTOR, SAID FIRST AND SECOND SHIELDING MEANS LIMITING THE DIRECTION OF DETECTION OF SAID FIRST AND SECOND DETECTOR MEANS, AND TIMING MEANS ELECTRICALLY CONNECTED TO SAID FIRST AND SECOND DETECTORS WHEREBY THE RATE OF FLOW OF SAID MATERIAL BETWEEN SAID FIRST AND SECOND DETECTOR MEANS CAN BE MEASURED.
