Реферат: 131. Pettit, C. E. Jan. 2. Electric furnaces.-An electrode furnace applicable for making calcium carbide is provided with means for regulating the electric pressure, to avoid moving the electrodes. The regulator is preferably connected to the high-tension coils of a transformer if one is used, or to the field-magnet coils of a direct-current dynamo, or the exciter of an alternator. As shown, a regulator e adjustable by a screw f is adapted to cut out groups of the high-tension coils a of a transformer in turn, each step preferably causing an alteration of two volts. The low-tension coils b are connected directly to the electrodes c, and may be cut out by the regulator instead of the high-tension coils.
