Interpolating arrangement for a precision transducer

Claim 1

A PRECISION TRANSDUCER COMPRISING: AN AUTOTRANSFORMER HAVING A SERIES OF TAPS FOR DEVELOPING EQUAL INCREMENTS OF VOLTAGE; A FIRST PAIR OF INDUCTIVE ELEMENTS DISPOSED IN MAGNETIC FLUX LINKAGE WITH SAID AUTOTRANSFORMER FOR DEVELOPING TWO EQUAL INDUCED VOLTAGES; AN ANNULAR MANDREL FORMED OF A SOFT MAGNETIC MATERIAL; A SECOND PAIR OF INDUCTIVE ELEMENTS WOUND ON SAID MANDREL, EACH OF SAID INDUCTIVE ELEMENTS OF SAID SECOND PAIR CONNECTED ACROSS A DIFFERENT INDUCTIVE ELEMENT OF SAID FIRST PAIR; SWITCH MEANS FOR CONNECTING ONE POINT ON EACH OF SAID INDUCTIVE ELEMENTS OF SAID FIRST PAIR TO ADJACENT AUTOTRANSFORMER TAPS PROGRESSIVELY ALONG THE SERIES; AND A CONTACT MOVABLE ALONG SAID SECOND PAIR OF INDUCTIVE ELEMENTS TO SELECTIVELY TAP ANY PORTION OF THE VOLTAGES DEVELOPED BY SAID FIRST PAIR OF INDUCTIVE ELEMENTS, THE MOVEMENT OF SAID CONTACT BEING SO SYNCHRONIZED WITH THE OPERATION OF SAID SWITCH MEANS THAT SAID CONTACT IS OPERATIVE AT ALL TIMES ON AN INDUCTIVE ELEMENT OF SAID SECOND PAIR CONNECTED TO AN INDUCTIVE ELEMENT OF SAID FIRST PAIR ENERGIZED BY CONDUCTIVE CONNECTION WITH SAID AUTOTRANSFORMER IN ADDITION TO MAGNETIC FLUX LINKAGE THEREWITH.
