5012. Cook, F. B. March 1. Resistances. - A heating resistance for a thermal cutout consists of a mixture of a good conductor such as graphite and a poor conductor such as pumice under cempression but not baked. The resistance block 11 is enclosed with an insulating-lining 13 and a metal disk 14 in a metallic shell 12. Projections 15 on the disk 14 make contact with a terminal piece 16. The edges of the shell 12 are turned over to hold the parts and compress the block.
