Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
108 words
A METHOD OF DETECTING AND MEASURING SMALL QUANTITIES OF WATER PRESENT IN LIQUID HYDROCARBON FUELS AS A SUSPENSION OF DEOPLETS HAVING A SIZE ON THE ORDER OF A FEW MICRONS, WHICH COMPRISES PASSING THE FUEL THROUGH A PLURALITY OF PASSAGES FORMED IN THE FIRST OF TWO DETECTOR ELECTRODES, ABRUPTLY ALTERING THE DIRECTION OF FLOW OF THE FUEL THROUGH A SHARP ANGLE AND PASSING THE FUEL THROUGH A GAP BETWEEN THE TWO DETECTOR ELECTRODES, THE WIDTH OF THE GAP BEING THREE THOUSANDTHS OF AN INCH, APPLYING A VOLTAGE ACROSS THE ELECTRODES, AND MEASURING THE ELECTRICAL RESISTANCE OF THE GAP BETWEEN THE TWO ELECTRODES WHILE THE FUEL IS FLOW THERETHROUGH.
Claim 2
Independent Claim

Claim 3
Dependent Claim
117 words
APPARATUS FOR DETECTING AND MEASURING SMALL QUANTITIES OF WATER PRESENT IN LIQUID HYDROCARBON FUELS AS A SUSPENSION OF DROPLETS OF WATER IN THE FUEL, WHICH COMPRISES A PAIR OF ELECTRICALLY INSULATED DETECTOR ELECTRODES HAVING A SPACE BETWEEN THEM, ONE DETECTOR ELECTRODE HAVING AT LEAST ONE PASSAGE FORMED THEREIN, THHE PASSAGES BEING IN COMMUNICATION WITH THE SPACE BETWEEN THE ELECTRODES AND BEING DISPOSED AT AN ABRUPT ANGLE THERETO, THE WIDTH OF THE SPACE BEING THREE THOUSANDTHS OF AN INCH, MEANS COUPLED TO THE ELECTRODES FOR APPLYING A SMALL VOLTAGE ACROSS THE ELECTRODES, AND MEANS COUPLED TO SAID VOLTAGE APPLYING MEANS FOR MEASURING THE ELECTRICAL RESISTANCE ACROSS THE SPACE BETWEEN THE ELECTRODES WHILE FUEL IN FLOWING THROUGH SAID SPACE.
