Electrical inductive apparatus having interleaved windings for providing a predetermined capacitive effect

Claim 1

AN ELECTRICAL TRANSFORMER COMPRISING A FIRST WINDING INCLUDING FIRST AND SECOND WINDING SECTION, A SAID FIRST AND SECOND WINDING SECTIONS EACH INCLUDING A PLURALITY OF TURNS OF ELECTRICAL CONDUCTIVE SHEET MATERIAL, THE TURNS OF SAID FIRST WINDING SECTION BEING CONTINUOUSLY INTERLEAVED WITH AT LEAST A PORTION OF THE TURNS OF SAID SECOND WINDING SECTION TO PROVIDE A PREDETERMINED CAPACITANCE BETWEEN SAID WINDING SECTIONS, INSULATING MEANS DISPOSED BETWEEN THE TURNS OF SAID FIRST AND SECOND WINDING SECTIONS ONE END OF EACH OF SAID FIRST AND SECOND WINDING SECTIONS BEING ADAPTED FOR CONNECTION TO AN EXTERNAL CIRCUIT, AND A SECOND WINDING DISPOSED IN INDUCTIVE RELATION WITH SAID FIRST WINDING, SAID CAPACITANCE BEING EFFECTIVELY CONNECTED IN SERIES WITH SAID FIRST WINDING WHEN SAID FIRST AND SECOND WINDING SECTIONS ARE CONNECTED TO AN EXTERNAL CIRCUIT, TO PROVIDE A VOLTAGE DROP ACROSS SAID CAPACITANCE WHICH VARIES WITH THE CURRENT FLOW THROUGH THE FIRST AND SECOND WINDING SECTIONS OF SAID FIRST WINDING, SAID TRANSFORMER BEING CAPABLE OF TRANSFORMING VOLTAGE DEPENDENT UPON THE RATIO OF TURNS IN SAID FIRST AND SECOND WINDINGS.
