Abstract
709,294. Electric immersion heaters. TRAUTMAN, O. C. Oct. 4, 1951 [July 25, 1951], No. 23171/51. Class 39 (3) A cylindrical refractory core A for a resistance helix 7, e.g. in an immersion heater in a lead bath, has a plurality of circumferentially spaced, helically arranged, radially projecting fins 9, and a plurality of circumferential, radially projecting ribs 13 longitudinally spaced on the core and projecting radially beyond the fins 9. The core A of the heating element comprises ceramic cylindrical sections 8, 12 alternately positioned on a metal rod 15, the sections 8 having spaced fins 9, 10, helically arranged on their surface, and the sections 12 having a continuous helical rib 13. The fins 10 and ribs 13 extend outwardly the same distance beyond the fins 9 to locate the core in a tube 1 in a container 2, e.g. the melting pot of a lead bath. The convolutions of the resistance helix 7 are positioned between adjacent ribs and fins, one end of the helix 7 being welded at 17 to the rod 15, and the other end to a strap 18 at 19, the rod 15 and strap 18 being taken out to suitable terminals. Refractory spacers 21, 23 are threaded on the tube 15, which is of reduced diameter at 24 to facilitate the bending of the core, with the tube 1, in the pot 2.
