J >r5cyiption : 4g, mandni connected at ends for electricheating by direct current; 48, rubber covering to be vulcanized. whole interior is electrically heated and vulcanization goes plans for heating mixing and calender rolls, of curing dryheat goods such as shoes, clothing, dress shields, etc., nospecific mention is made, although they all come under the broad claims that are adaptation of the new processhowever, seems to fit the curing ofdipped goods, and that seems to bethe only exception as far as gen-eral lines go. The electric heat is developedby placing magnet coils in re-cesses or grooves in the faces ofthe platens or molds, connectingwith an alternating current, whichestablishes rapidly alternatingmagnetic fields with the attend-ing hysteresis effects, and foucaultor eddy currents. The mold is closed by the magnetic attrac-tion of its parts induced by an electric current passing throughcoils imbedded in the parts of the mold. A magn
