Liquid level sensing system

Claim 1

IN A FLUID LEVEL SENSING SYSTEM, THE COMBINATION COMPRISING A FLUID RESERVOIR, AN ALTERNATOR, A MAGNETIZABLE CORE, A FIRST MAGNETIZING COIL COUPLED TO INDUCE A MAGNETIC FLUX IN SAID CORE AND IN SERIES CIRCUIT WITH SAID ALTERNATOR, A SECOND MAGNETIZING COIL COUPLED TO SAID CORE TO INDUCE A MAGNETIC FLUX IN SAID CORE IN OPPOSITION TO THE MAGNETIC FLUX INDUCED BY SAID FIRST MAGNETIZING COIL, SAID SECOND MAGNETIZING COIL IN SERIES CIRCUIT WITH SAID ELECTRICAL GENERATOR, A FIRST RESISTOR MEANS IN SERIES CIRCUIT WITH SAID FIRST MAGNETIZING COIL AND A SECOND RESISTOR MEANS IN SERIES CIRCUIT WITH SAID SECOND MAGNETIZING COIL, SAID RESISTORS LOCATED IN SAID FLUID RESERVOIR AT TWO DIFFERENT LEVELS TO SENSE THE LEVEL OF THE FLUID IN SAID RESERVOIR AND A FLOW LAMP MEANS COUPLED TO SAID CORE BY A SENSING COIL FOR CONDUCTING ONLY WHEN A SUBSTANTIAL UNCANCELED FLUX IS INDUCED IN SAID REACTOR BY THE FLUID LEVEL ATTAINING A GIVEN CONDITION, SAID SUBSTANTIAL UNCANCELED FLUX CAUSING A VOLTAGE AND CORRESPONDING CURRENT OF A PREDETERMINED MAGNITUDE SUFFICIENT TO BE CONDUCTED BY SAID GLOW LAMP MEANS TO BE INDUCED IN SAID SENSING COIL.
