Shielding arrangement for transformer

Claim 1

A TRANSFORMER HAVING A CLOSED CORE CONSISTING ESSENTIALLY OF FERROMAGNETIC MATERIAL PROVIDING A SUBSTANTIALLY CONTINUOUS CLOSED LOW RELUCTANCE PATH AND INCLUDING FIRST AND SECOND FERROUS LEGS, SAID LEGS EXTENDING PARALLEL TO AND SPACED FROM EACH OTHER; A PRIMARY WINDING INCLUDING FIRST AND SECOND COILS, A SECONDARY WINDING INCLUDING FIRST AND SECOND COILS; EACH OF SAID FIRST COILS HAVING ITS TURNS CIRCUMSCRIBING ONE OF SAID LEGS AND SAID FIRST COILS BEING SUPPORTED SIDE BY SIDE ON SAID ONE OF SAID LEGS; EACH OF SAID SECOND COILS HAVINGITS TURNS CIRCUMSCRIBING THE OTHER OF SAID LEGS AND SAID SECOND COILS BEING SUPPORTED SIDE BY SIDE ON SAID OTHER OF SAID LEGS, FIRST D.C. CONDUCTIVE SHIELDING HAVING AN OCTIFORM SURFACE SEPARATING SAID FIRST AND SECOND COILS OF SAID PRIMARY WINDING FROM SAID SECONDARY WINDING; SECOND D.C. CONDUCTIVE SHIELDING HAVING AN OCTIFORM SURFACE SEPARATING SAID FIRST AND SECOND COILS OF SAID SECONDARY WINDING FROM THE SAID OCTIFORM SURFACE OF SAID FIRST D.C. CONDUCTIVE SHIELDING; THE SAID SHIELDINGS BEING INSULATED EACH FROM THE OTHER, AND EACH THEREOF SURROUNDING EACH OF SAID LEGS INDIVIDUALLY AND BOTH SAID LEGS AS A WHOLE, SO THAT EACH SAID SHIELDING HAS A FIGURE-8 CONFIGURATION THE BIGHTS OF WHICH CIRCUMSCRIBE SAID LEGS AND MERGE IN A SEPTUM LYING BETWEEN SAID LEGS, SAID BIGHTS AND SAID SEPTUM DEFINING SAID OCTIFORM SURFACE OF EACH SAID SHIELDING.
