Indicating device

Claim 1

AN ELECTROMAGNETIC INDICATOR COMPRISING: A PANEL HAVIN A WINDOW, A STATOR HAVING AN ANNULAR FERROMAGNETIC CORE FOR ESTABLISHING ANY ONE OF A PLURALITY OF DISCRETELY ORIENTED MAGNETIC FIELDS, THE CORE HAVINGA PLURALITY OF INWARDLY PROTRUDING RADIAL POLES, THE RADIAL POLES BEING SPACED AROUND THE CORE SO THAT NO RADIL POLE IS DIAMETRICALLY OPPOSITE ANOTHER RADIAL POLE, THE STATOR INCLUDING A PLURALITY OF WINDINGS, EACH WINDING BEING MOUNTED UPON A DIFFERENT RADIAL POLE AND BEING ARRANGED TO BE SEPARATELY ENERGIZABLE BY AN ELECTRICAL SIGNAL, A ROTOR HAVING A MAGNETIC ENCIRCLED BY THE STATOR''S ANNULAR CORE, THE ROTOR BEING PIVOTALLY MOUNTED TO PERMIT THE MAGNETIC TO TURN ABOUT AN AXIS AT THE CORE''S GEOMETRIC CENTER, THE MAGNETIC HAVING TWO DIAMETRICALLY OPPOSED SALIENT POLES OF OPPOSITE MAGNETIC POLARITY, THE ROTOR INCLUDING A DRUM UPON WHOSE PERIPHERY SYMBOLS ARE MARKED, THE DRUM BEING POSITIONED TO PRESENT THE SYMBOLS IN THE WINDOW OF THE PANEL ,EACH ELECTRICALLY ENERGIZED WINDING OF THE STATOR BEING OPERATIVE TO PRODUCE A TURNING FORCE UPON THE MAGNET WHICH CONSTRAINS THE MAGNET TO ROTATE INTO ALIGNMENT WITH THE RADIAL POLE OF THE ENERGIZED WINDING, EACH DIFFERENT ALIGNED POSITION OF THE MAGNETIC CAUSING TH DRUM TO BE STATIONED SO THAT A DIFFERENT SYMBOL IS CENTERED IN THE PANEL''S WINDOW, AND THE MAGNETIC CIRCUIT ESTABLISHED THROUGH THE CORE BY THE MAGNET''S FLUX CAUSING THE MAGNET TO BE HELD IN THE ALIGNED POSITION WHEN THE STATOR IS ELECTRICALLY DE-ENERGIZED.
