Claim 1
Independent Claim
138 words
IN A METHOD OF MONITORING THE RATIO OF VAPOR VOLUME TO LIQUID VOLUME OF A MOTOR FUEL INCLUDING A PLURALITY OF HYDROCARBONS, THE STEPS OF CONVEYING THE FUEL TO A LOCATION AT WHICH THE VAPOR AND THE LIQUID OF THE FUEL ARE IN SUBSTANTIAL EQUILIBRIUM AT A PREDETERMINED TEMPERATURE, CONVEYING THE FUEL AWAY FROM SAID LOCATION, VARYING AT LEAST ONE OF THE RATES OF FLOW OF FUEL TO AND FROM SAID LOCATION TO RETAIN THE PRESSURE OF SAID VAPOR SUBSTANTIALLY EQUAL TO A PREDETERMINED VALUE, GENERATING A FIRST SIGNAL REPRESENTATIVE OF THE FLOW OF FUEL TO SAID LOCATION, GENERATING A SECOND SIGNALS REPRESENTATIVE OF THE FLOW OF FUEL AWAY FROM SAID LOCATION, AND GENERATING AN OUTPUT SIGNAL RESPONSIVE TO SAID FIRST AND SECOND SIGNALS AND REPRESENTATIVE OF THE RATIO OF VAPOR VOLUME TO LIQUID VOLUME OF SAID FUEL.
Claim 2
Dependent Claim
31 words
IN THE METHOD RECITED IN CLAIM 4, THE FURTHER STEP FO CONTROLLING THE COMPOSITION OF SAID FUEL TO MAINTAIN SAID RATIO OF VAPOR VOLUME TO LIQUID VOLUME AT A PREDETERMINED VALUE.
