Auto-transformer of core-form type having tapped winding disposed between axially spaced sections of high and low voltage windings

Claim 1

A TRANSFORMER COMPRISING A HIGH VOLTAGE TERMINAL, A LOW VOLTAGE TERMINAL, A MAGNETIC CORE MEMBER, HIGH AND LOW VOLTAGE WINDINGS DISPOSED IN INDUCTIVE RELATION WITH SAID MAGNETIC CORE MEMBER, SAID HIGH AND LOW VOLTAGE WINDINGS BEING DISPOSED IN CONCENTRIC RELATION, EACH OF SAID HIGH AND LOW VOLTAGE WINDINGS BEING DIVIDED INTO FIRST AND SECOND SPACED SECTIONS, EACH OF THE FIRST AND SECOND SPACED SECTIONS HAVING INNER ENDS ADJACENT THE SPACE BETWEEN THE SECTIONS, AND OUTER ENDS, THE OUTER ENDS OF SAID FIRST AND SECOND HIGH VOLTAGE WINDING SECTIONS EACH BEING CONNECTED TO SAID HIGH VOLTAGE TERMINAL, THE OUTER ENDS OF SAID FIRST AND SECOND LOW VOLTAGE WINDING SECTIONS BEING CONNECTED IN COMMON, THE INNER ENDS OF SAID FIRST AND SECOND HIGH AND LOW VOLTAGE WINDING SECTIONS ALL BEING CONNECTED IN COMMON, A TAPPED WINDING SECTION, SAID TAPPED WINDING SECTION BEING DISPOSED IN THE SPACE BETWEEN SAID SPACED HIGH AND LOW VOLTAGE WINDING SECTIONS, MEANS CONNECTING THE COMMON CONNECTION OF THE INNER ENDS OF SAID FIRST AND SECOND HIGH AND LOW VOLTAGE WINDING SECTIONS TO SAID LOW VOLTAGE TERMINAL THROUGH SAID TAPPED WINDING SECTION, FIRST AND SECOND STATIC PLATE MEMBERS CONNECTED TO SAID LOW VOLTAGE TERMINAL, SAID FIRST AND SECOND STATIC PLATE MEMBERS BEING DISPOSED BETWEEN SAID TAPPED WINDING PORTION AND SAID FIRST AND SECOND HIGH VOLTAGE WINDING SECTIONS, RESPECTIVELY, EACH OF SAID FIRST AND SECOND HIGH VOLTAGE WINDING SECTIONS AND SAID TAPPED WINDING SECTION HAVING A PLURALITY OF STACKED PANCAKE COILS EACH HAVING A PLURALITY OF TURNS INTERCONNECTED IN A PREDETERMINED ARRANGEMENT WHICH DISTRIBUTES SURGE VOLTAGES ACROSS SAID WINDING SECTION IN A SUBSTANTIALLY UNIFORM MANNER.
