Claim 1
Independent Claim
177 words
ELECTRICAL INDUCTIVE APPARATUS FOR CONNECTION TO AN ALTERNATING CURRENT SOURCE AND A LOAD CIRCUIT COMPRISING A MAGNETIC CORE, A FIRST WINDING INCLUDING A PLURALITY OF TURNS OF ELECTRICALLY CONDUCTIVE SHEET MATERIAL DISPOSED IN INDUCTIVE RELATION WITH SAID MAGNETIC CORE, A SECOND WINDING INCLUDING A PLURALITY OF TURNS OF ELECTRICALLY CONDUCTIVE SHEET MATERIAL DISPOSED IN INDUCTIVE RELATION WITH SAID FIRST WINDING, SAID FIRST AND SECOND WINDINGS HAVING A DIFFERENT NUMBER OF TURNS TO PROVIDE A RATIO OF TRANSFORMATION BETWEEN SAID WINDINGS, THE TURNS OF SAID SECOND WINDING BEING CONTINUOUSLY INTERLEAVED WITH A PORTION OF THE TURNS OF SAID FIRST WINDING TO PROVIDE A PREDETERMINED CAPACITANCE BETWEEN THE ADJACENT TURNS OF SAID FIRST AND SECOND WINDINGS, ELECTRICAL INSULATING MEANS DISPOSED BETWEEN THE TURNS OF SAID FIRST AND SECOND WINDINGS, ONE END OF EACH OF SAID FIRST AND SECOND WINDINGS BEING ADAPTED FOR CONNECTION TO DIFFERENT SIDES OF SAID ALTERNATING CURRENT SOURCE, SAID FIRST WINDING BEING CONNECTED TO THE OTHER SIDE OF SAID ALTERNATING CURRENT SOURCE THROUGH SAID CAPACITANCE, SAID SECOND WINDING BEING ADAPTED FOR CONNECTION TO THE LOAD CIRCUIT.
