Adjustable voltage rectifier

Claim 1

AN ADJUSTABLE VOLTAGE RECTIFIER COMPRISING A PLURALITY OF ADJUSTABLE TRANSFORMERS, EACH TRANSFORMER HAVING A PARAMAGNETIC CORE, A PRIMARY WINDING WOUND THEREON, A SECONDARY WINDING WOUND THEREON, A BRUSH MOVABLE ON THE SECONDARY WINDING IN ELECTRICAL ENGAGEMENT CONTINUOUSLY WITH AT LEAST ONE TURN THEREOF, AND MEANS FOR MOVING THE BRUSH; MEANS INTERCONNECTING THE BRUSH MOVING MEANS OF EACH OF THE TRANSFORMERS TO CAUSE THEM TO MOVE IN UNISON WHEN MOVED; MEANS FOR CONNECTING THE PRIMARY WINDINGS TO A MULTIPLE PHASE SOURCE OF A.C. WITH EACH PRIMARY WINDING BEING ENERGIZED FROM ONE OF THE PHASES; A PAIR OF D.C. OUTPUT TERMINALS WITH EACH TERMINAL BEING A PLATE FORMED OF CONDUCTING MATERIAL AND HAVING APERTURES FORMED THEREIN; A FIRST GROUP OF ONE-WAY VALVE MEANS CONDUCTIVE IN THE SAME DIRECTION CONNECTED TO ONE PLATE BY EACH ONE-WAY VALVE MEANS HAVING A STUD POSITIONED IN AN APERTURE TO BE IN ELECTRICAL AND HEAT CONDUCTIVE RELATION TO THE PLATE; A SECOND GROUP OF ONE-WAY VALVE MEANS CONNECTED TO THE OTHER PLATE BY EACH ONE-WAY VALVE MEANS HAVING A STUD POSITIONED IN AN APERTURE TO BE IN ELECTRICAL AND HEAT CONDUCTIVE RELATION TO THE PLATE WITH EACH OF THE ONE-WAY VALVE MEANS IN THE SECOND GROUP ALL BEING CONDUCTIVE IN THE SAME DIRECTION BUT REVERSED FROM THE CONDUCTIVE DIRECTION OF THE FIRST GROUP; AND MEANS CONNECTING THE BRUSHES OF THE TRANSFORMERS TO THE ONE-WAY VALVE MEANS WITH EACH BRUSH BEING CONNECTED TO ONE-WAY VALVE MEANS IN EACH GROUP WHEREBY MOVEMENT OF THE BRUSHES IN UNISON PROVIDES AN ADJUSTABLE D.C. VOLTAGE AT THE OUTPUT TERMINAL, SAID TRANSFORMERS BEING MOUNTED TO BE VERTICALLY ALIGNED WITH THE PLATES SUPPORTED THEREON TO EXTEND VERTICALLY IN PARALLEL SPACED RELATION AND HAVING THE ONEWAY VALVE MEANS POSITIONED BETWEEN THE PLATES.
