THE METHOD OF MAKING AN ELECTRICAL CONDENSER WHICH INCLUDES LOOSELY WINDING LAYERS OF SHEET METAL WITH LAYERS OF SHEET INSULATION THEREBETWEEN, IMPREGNATING SAID LOOSELY WOUND CONDENSER UNDER VACUUM WITH A FLOWABLE, HEAT SETTABLE, SYNTHETIC RESIN COMPOUND WHICH IS ADAPTED TO SHRINK UPON SOLIDIFICATION, SUBJECTING TWO OPPOSED SIDES ONLY OF SAID CONDENSER TO PRESSURE BETWEEN SUBSTANTIALLY FLAT SURFACES WHICH ARE MOVABLE TOWARD EACH OTHER BY SAID PRESSURE WHILE THE COMPOUND IS FLOWABLE AND WITHOUT RESTRICTION OTHER THAN THE CONDENSER ITSELF, SAID PRESSURE BEING SUFFICIENT TO FULLY COMPRESS AND FLATTEN THE CONDENSER TO EXPEL EXCESS COMPOUND AND PRESS ADJACENT LAYERS INTO CLOSE ENGAGEMENT, AND CONTINUING THE APPLICATION OF SAID PRESSURE WITH HEATING UNTIL THE COMPOUND REMAINING IN THE CONDENSER SOLIDIFIES.
