Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
78 words
THE METHOD OF MEASURING THE LIQUID SATURATION DISTRIBUTION OF A POROUS MATERIAL WHICH COMPRISES ENCASING A GENERALLY CYLINDRICAL SAMPLE OF SAID MATERIAL SUBSTANTIALLY SATURATED WITH A LIQUID IN A CLOSE FITTING NONCONDUCTIVE HOUSING, PASSING AN ALTERNATING ELECTRICAL CURRENT THROUGH THE LENGTH OF SAID SAMPLE, AND CAPACITATIVELY AND DIRECTLY MEASURING THE VOLTAGE DROP BETWEEN ANY TWO POINTS ALONG THE CORE HOUSING, THE SAID VOLTAGE DROP VARYING INVERSELY WITH THE DEGREE OF SATURATION OF THE CORE BETWEEN SAID TWO POINTS.
Claim 2
Independent Claim
78 words

Claim 3
Dependent Claim
97 words
IN A SYSTEM FOR ELECTRICALLY MEASURING THE SATURATION DISTRIBUTION OF A SAMPLE OF POROUS MATERIAL, IN COMBINATION; AN ELONGATED GENERALLY CYLINDRICAL NONCONDUCTIVE HOUSING ENCLOSING A CORE SAMPLE OF POROUS MATERIAL, A PAIR OF CAPACITANCE PICKUP ELECTRODES SLIDABLY MOUNTED A FIXED DISTANCE APART ON SAID CORE HOUSING, A DEVICE CONNECTED TO SAID ELECTRODES FOR MEASURING THE VOLTAGE DROP BETWEEN THEM AS THEY ARE MOVED TOGETHER ALONG THE CORE HOUSING, AND MEANS FOR ELECTRICALLY CONVERTING THE INDIVIDUAL VOLTAGE DROPS THUS MEASURED INTO INSTRUMENT READINGS WHICH ARE A FUNCTION OF THE DEGREE OF SATURATION OF THE CORE BETWEEN SAID ELECTRODES.
Claim 4
Dependent Claim
97 words
