Claim 1
Independent Claim
148 words
A SYSTEM FOR REGUATING THE VISCOSITY OF FUEL OIL TO PROVIDE EFFICIENT COMBUSTION WHICH COMPRISES, (A) A FUEL OIL STORAGE UNIT HAVING VALVE CONTROLLED HEATING MEANS, (B) A CONDUIT ASSEMBLY FOR CONNECTING SAID FUEL STORAGE UNIT WITH COMBUSTION APPARATUS, (C) SAID CONDUIT ASSEMBLY HAVING A FIRST ZONE FOR LAMINAR FLOW OF THE FUEL OIL BETWEEN ITS INLET AND OUTLET AND A SECOND ZONE FOR TUBULENT FLOW OF THE FUEL OIL BETWEEN ITS INLET AND OUTLET, (D) A FIRST TRANSDUCER OPERATIVE BY DIFFERENTIAL PRESSURE EXISTING BETWEEN THE INLET AND OUTLET OF SAID FIRST ZONE TO PROVIDE A FIRST OUTPUT VOLTAGE AND A SECOND TRANSDUCER OPERATIVE BY DIFFERENTIAL PRESSURE EXISTING BETWEEN THE INLET AND OUTLET OF SAID SECOND ZONE TO PROVIDE A SECOND OUTPUT VOLTAGE AND (E) AN ANALOG MODULE OPERATIVE BY SAID FIRST AND SECONE OUTPUT VOLTAGES FOR PRODUCING A SIGNAL VOLTAGE TO OPERATE THE VALVE CONTROLLED HEATING MEANS.
