Method of analyzing compositions

Claim 1

THE METHOD OF DETERMINING CHANGES IN THE CONCENTRATIONS OF TWO ELEMENTS IN A MATERIAL IN A VESSEL, WHICH COMPRISES FIRST BOMBARDING WITH NEUTRONE IN SAID VESSEL A SIMILAR MATERIAL CONTAINING KNOWN CONCENTRATIONS OF SAID ELEMENTS, SIMULTANEOUSLY MEASURING THE COUNTING RATES OF THERMAL NEUTRONE PASSING THROUGH DIFFERENT DISTANCES IN SAID SIMULAR MATERIAL, PLOTTING A FAMILLY OF CROSSED CURVES SHOWING THE VARIATION IN DENSITY OF EACH OF SAID ELEMENTS IN SAID SIMULAR MATERIAL AS A FUNCTION OF THE VARIATIONS IN DENSITY OF ANOTHER OF SAID ELEMENTS FOR PREDETERMINED DIFFERENT COUNTING RATES AT EACH OF SAID DISTANCES, REPEATING THE AFOREMENTIONED STEPS OF BOMBARDING WITH NEUTRONS AND MEASURING THERMAL NEUTRONS WITH SAID FIRST MENTION MATERIAL IN SAID VESSEL TO OBTAIN THE CONTING RATES AT SAID TWO DISTANCES, AND THEN REFERRING TO SAID CURVES TO OBTAIN THE DENSITIES OF SAID ELEMENTS IN THE FIRST MENTIONED MATERIAL, THE POINTS INTERSECTION OF THE CURVES FOR THE COUNTING RATES SUBSEQUENTLY OBTAINED AT SAID DIFFERENT DISTANCES WITH THE FIRST MENTIONED MATERIAL CONSTITUTING AN INDICATION OF THE DENSITIES OF THE TWO ELEMENTS BEING MEASURED.

Claim 2

THE METHOD OF DETERMINING CHANGES IN THE CONCENTRATIONS OF TWO ELEMENTS IN A MATERIAL IN A VESSEL, WHICH COMPRISES FIRST BOMBARDING WITH NEUTRONE IN SAID VESSEL A SIMILAR MATERIAL CONTAINING KNOWN CONCENTRATIONS OF SAID ELEMENTS, SIMULTANEOUSLY MEASURING THE COUNTING RATES OF THERMAL NEUTRONE PASSING THROUGH DIFFERENT DISTANCES IN SAID SIMULAR MATERIAL, PLOTTING A FAMILLY OF CROSSED CURVES SHOWING THE VARIATION IN DENSITY OF EACH OF SAID ELEMENTS IN SAID SIMULAR MATERIAL AS A FUNCTION OF THE VARIATIONS IN DENSITY OF ANOTHER OF SAID ELEMENTS FOR PREDETERMINED DIFFERENT COUNTING RATES AT EACH OF SAID DISTANCES, REPEATING THE AFOREMENTIONED STEPS OF BOMBARDING WITH NEUTRONS AND MEASURING THERMAL NEUTRONS WITH SAID FIRST MENTION MATERIAL IN SAID VESSEL TO OBTAIN THE CONTING RATES AT SAID TWO DISTANCES, AND THEN REFERRING TO SAID CURVES TO OBTAIN THE DENSITIES OF SAID ELEMENTS IN THE FIRST MENTIONED MATERIAL, THE POINTS INTERSECTION OF THE CURVES FOR THE COUNTING RATES SUBSEQUENTLY OBTAINED AT SAID DIFFERENT DISTANCES WITH THE FIRST MENTIONED MATERIAL CONSTITUTING AN INDICATION OF THE DENSITIES OF THE TWO ELEMENTS BEING MEASURED.

Claim 3

AN APPARATUS FOR MEASURING THE ONCENTRATION OF TWO ELEMENTS IN A FLUID COMPOSITION CONTAINED IN A VESSEL COMPRISING AN ELONGATED HOUSING ADAPTED TO BE INSERTED IN SAID COMPOSITION WITHIN THE VESSEL, A SOURCE OF NEUTRONS WITHIN SAID HOUSING A DETECTOR OF THERMALNEUTRONS WITHIN SAID HOUSING IN THE IMMEDIATE VICINITY OF SAID SOURCES AND AT LEAST ONE OTHER SIMULAR THERMAL NEUTRON DECTORS IN SAID HOUSING AND SPACES FROM SAID SOURCE BY A DISTANCE SUCH THAT NEUTRONS MEASURED THEREBY WILL HAVE TRAVERSED AN AMOUNT OF SAID COMPOSITION HAVING THE EQUIVALENT SLOWING DOWN POWER OF AT LEAST THREE INCHES OF WATER.

Claim 4

AN APPARATUS FOR MEASURING THE ONCENTRATION OF TWO ELEMENTS IN A FLUID COMPOSITION CONTAINED IN A VESSEL COMPRISING AN ELONGATED HOUSING ADAPTED TO BE INSERTED IN SAID COMPOSITION WITHIN THE VESSEL, A SOURCE OF NEUTRONS WITHIN SAID HOUSING A DETECTOR OF THERMALNEUTRONS WITHIN SAID HOUSING IN THE IMMEDIATE VICINITY OF SAID SOURCES AND AT LEAST ONE OTHER SIMULAR THERMAL NEUTRON DECTORS IN SAID HOUSING AND SPACES FROM SAID SOURCE BY A DISTANCE SUCH THAT NEUTRONS MEASURED THEREBY WILL HAVE TRAVERSED AN AMOUNT OF SAID COMPOSITION HAVING THE EQUIVALENT SLOWING DOWN POWER OF AT LEAST THREE INCHES OF WATER.
