Claim 3
Independent Claim
63 words
THE METHOD OF MAKING AN ELECTRICAL CAPACITOR HAVING A CAPATOR SECTION IN A CASING, WHICH COMPRISES FILING THE CASING WITH DIELECTRIC LIQUID AT ELEVATED TEMPERATURE, COOLING THE FILLED CASING IN THE PRESENCE OF A GAS, SEALING THE CASING, HEATING AND THEN COOLING THE SEALED CASING, UNSEALING THE CASING, REPEATING THE DESCRIBED SERIES OF STEPS FOUR TO EIGTH TIMES, AND FINALLY SEALING THE CASING.
