Abstract

483,206. Circulating furnace atmospheres. MACDONALD, J. Aug. 18, 1937, No. 22694. Drawings to Specification. [Class 51 (ii)] The atmosphere-circulating fan of a heat treatment furnace is cut out of action when a predetermined temperature, e.g. 750‹ C., is reached in the furnace. The heat-sensitive control element, which may be the same as that provided for temperature control, may be in series with a door switch. The fan may be restarted automatically on fall of temperature below the predetermined value.
