Abstract

444,108. Case - hardening. HUME, R. H., 24, Priory Road, and CREEDY, L. D., 10, Frederick Road, both in Edgbaston, Birmingham. Sept. 13, 1934, No. 26270. [Class 72] Articles to be case-hardened are heated in a compartment c of a closed box a out of contact with carbonaceous material in compartments d, the gases evolved passing through perforated vertical partitions e into contact with the articles.
