Title: Improvements in or relating to resistors for electric furnaces
IPC: F27D11/00
Filed: 1939-07-07
Abstract: 530,949. Couplings. SOC. ANON DES MANUFACTURES DES GLACES ET PRODUITS CHIMIQUES DE ST.-GOBAIN, CHAUNY & CIREY. July 7, 1939, No. 19827. Convention date, July 28, 1938. [Class 38 (i)] A current supply head for an hermatically enclosed resistance rod 1 of carbon &c. consists of a metallic shell 3 sealed to the sheath 2 or furnace wall by which the rod is enclosed, and containing a conducting liquid 5, such as molten tin, in which the end of the rod 1 is immersed. Access of the liquid 5 to the interior of the sheath 2 is prevented by a joint 8, and the conductivity of the end of the rod is increased by forming a hollow a, b therein into which the liquid enters. The head may have a removable portion to give access for the removal of the rod 1, for example the portion 9, Fig. 5, may be screwed into the fixed portion 6 with a graphite bush 8 between. The liquid 5 may be kept away from the end 12 of the head, to prevent solidification, by a second bush 11, the necessary cooling of the head being effected by annular fins or by a jacket 13. If the head has a removable cap 3a, Fig. 8, this may press a sleeve 17 against bushes 8a, 8b acting through a cylinder 15 which is perforated to give direct liquid connection between the head 3 and rod 1. In a vertically mounted modification the sheath 2 carries a cup 3e, Fig. 11, in which the liquid is contained and the rod carries a bell 3f dipping into the cup, the lower end of the rod hanging in liquid contained in a cup 3g and protected by a covering of fusible glass 23. The conductivity of a rod of amorphous carbon may be increased at its ends or other zones, e.g. at intermediate supports, by converting it locally into graphite. In order to lessen the drop of pressure within the sheath on cooling, to prevent sucking in the liquid 5, hollows may be formed in the ends of the rod connected by a channel to the interior of the sheath.
