Toroid transformer electrostatic shield

Claim 1

IN A TOROID TRANSFORMER, THE COMBINATION OF: A TORODIAL BOBBIN OF CONDUCTIVE MATERIAL; A FERROMAGNETIC TAPE WRAPPED CIRCUMFERENTIALLY ABOUT AND INSULATED FROM SAID BOBBIN OF CONDUCTIVE MATERIAL; INSULATION MATERIAL WRAPPED UPON SAID BOBBIN, LEAVING ONLY A SMALL SPACE OF SAID CONDUCTIVE MATERIAL OF SAID BOBBIN EXPOSED; AN ELECTROSTATIC SHIELD PLATE INSERTED ACROSS THE DIAMETER OF SAID BOBBIN, MAKING ELECTRICAL AND MECHANICAL CONTACT WITH SAID CONDUCTIVE MATERIAL OF SAID TOROIDAL BOBBIN ONLY AT SAID EXPOSED SMALL SPACE, SAID SHIELD BEING IN A PLANE PERPENDICULAR TO THE PLANE OF THE CIRCUMFERENCE OF SAID BOBBIN, SAID BOBBIN, SAID FERROMAGNETIC TAPE, AND SAID INSULATING MATERIAL FORMING AN INSULATED TOROIDAL CORE WITH SAID SHIELD INSERTED THEREIN; A PRIMARY WINDING WOUND ON SAID CORE ON ONE SIDE OF SAID SHIELD; AND A SECONDARY WINDING WOUND ON SAID CORE ON THE OTHER SIDE OF SAID SHIELD OPPOSITE SAID PRIMARY WINDING, WHEREBY, THE INTERWINDING CAPACITANCES BETWEEN SAID PRIMARY WINDING AND SAID SECONDARY WINDING ARE A MINIMUM AND SAID SHIELD THEREBY PROVIDES A MAXIMUM INTERWINDING ELECTROSTATIC SHIELDING AGAINST ELECTROSTATICALLY INDUCED POTENTIALS BETWEEN SAID WINDINGS TO REDUCE INTERFERENCE AND NOISE THAT MAY BE OTHERWISE GENERATED IN THE USE OF SAID TRANSFORMER.
