Tuneable inductor having a fixed arcuate conductor turn in series with an inductively coupled variable arcuate conductor turn

Claim 1

A TUNABLE INDUCTOR COMPRISING A FIRST ARCUATE CONDUCTIVE TURN HAVING A FIXED SELF-INDUCTANCE, AND A SECOND ARCUATE CONDUCTIVE TURN CONNECTED IN SERIES WITH SAID FIRST TURN, SAID TURNS BEING DISPOSED IN MUTUAL ADDITIVE INDUCTIVE RELATION TO EACH OTHER, A CONDUCTIVE WIPED MOUNTED FOR RELATIVE ROTATION WITH RESPECT TO SAID TURNS AND HAVING ONE END IN VARIABLE ELECTRICAL ENGAGEMENT WITH AND ALONG SAID SECOND TURN AND CONDUCTIVE Y CONNECTED TO A POINT ON SAID SECOND TURN SO THAT IT PROVIDES A SHORT CIRCUIT OF THE PORTION OF SAID SECOND TURN BETWEEN ITS CONTACT THEREWITH AND SAID POINT AND PROVIDES AN UNSHORTED PORTION OF SAID SECOND TURN, THE ARRANGEMENT BEING SO DISPOSED THAT, AS THE WIPER PROGRESSIVELY INCREASES THE SHORTED PORTION OF SAID SECOND TURN, IT PROGRESSIVELY DECREASES THE UNSHORTED PORTION THEREOF.
