Abstract
116,661. Thompson, C. H. Dec. 24,1917. Carbon.-Anthracite, preferably of the size of peas or nuts, is employed as packing for carbon electrodes in the process of baking them, and is thus prepared for use in the manufacture of subsequent batches of electrodes. Volatile matter from the retorts may be burnt with the gas employed for heating. Temperatures of 1200-1500‹ C. are suitable.
