Claim 1
Independent Claim
92 words
A METHOD OF CONTROLLING THE OPERATION OF A CARBON BLACK PRODUCING FURNACE HAVING A CYLINDRICAL REACTION CHAMBER WITH A FIRST AXIAL OPENING IN ONE END THEREOF AND A SECOND OPENING IN THE SIDE WALL THEREOF TANGENTIAL TO THE SIDE WALL, WHICH COMPRISES PASSING A HYDROCARBON CONVERSION OIL TO SAID CHAMBER THROUGH SAID FIRST OPENING PASSING AIR TO SAID CHAMBER THROUGH SAID SECOND OPENING, MEASURING THE DIELECTRIC PROPERTIES OF SAID CONVERSION OIL PASSED TO SAID CHAMBER, AND ADJUSTING THE RATIO OF AIR TO OIL PASSED TO SAID CHAMBER IN RESPONSE TO SAID MEASUREMENT.
