Buoyancy type apparatus for determining hydrogen content in fluids with gamma rays

Claim 1

APPARATUS FOR MEASURING THE RATIO OF HYDROGEN ATOMS TO REMAINING ATOMS IN FLUIDS, COMPRISING A COMBINATION: A CONTAINER FOR THE FLUID; A HOLLOW CARRIER DISPOSED IN SAID CONTAINER AND F OATING IN THE FLUID THEREIN AND COMPLETELY SUBMERGED AT ALL TIMES; A GAMMA-RAY SOURCE SITUATED IN THE CENTER OF SAID CARRIER; AT LEAST ONE BUOYANCY ADJUSTMENT CHAIN SECURED TO SAID CARRIER SUSPENDED FROM SAID CARRIER AND PORTIONS OF SAID CHAIN SUSPENDED FROM SAID CARRIER AND OTHER PORTIONS OF SAID CHAIN RESTING ON THE BOTTOM OF SAID CONTAINER; AND GAMMA-RAY RECEIVING MEANS BEING CENTRALLY AFFIXED TO THE TOP OF SAID CONTAINER SO THAT THE DISTANCE BETWEEN SAID GAMMA-RAY SOURCE AND SAID RECEIVING MEANS CONSTITUTES THE MEASURING REGION, SAID DISTANCE BEING VARIABLE WITH VARYING DENSITY OF SAID FLUID, WHEREIN THE PRODUCT OF SAID DISTANCE AND SAID DENSITY IS MAINTAINED CONSTANT BY PORTIONS OF SAID BUOYANCY ADJUSTMENT CHAIN SUSPENDED BETWEEN SAID CARRIER AND SAID BOTTOM OF THE CONTAINER.
