By means of the poles, c and d, of an electro-magneteicited by the windings, e, a rotating arc is producedbetween the electrode, a, and the perforated electrode, h,these being cooled by water entering at / and o respectively,and leaving at g and p. The gases to be treated enter underpressure at i, the current of gas being deflected by theedge, r, towards the centre of the arc. In order to avoidshort-circuits of the current between the two electrodes, acooled current of inert gas enters through the channel, h,spreading into the form of a cone, so that the arc forms amantle above it, thus increasing the resistance of thecentral part of the space situated between the two elec-trodes.—B.
