Abstract

386,412. Wire &c. heaters. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London.-(Assignees of Patent- Treuhand-Ges. fur Elektrische Gluhlampen ; 11, Ehrenbergstrasse, Berlin.) Dec. 9, 1931, No. 34197. Convention date, Dec. 10, 1930. [Classes 39 (iii) and 126.] An apparatus for heating a continuously moving wire, thread, band &c. comprises a heated tube 2 surrounded by a jacket of heatinsulating material 3 having a slot 5, which allows the apparatus to be swung about the pivot 1 clear of the wire &c. The tube may be heated internally by a gas burner 7, as shown in Fig. 1, or by an electric resister 18, Fig. 4, and in the latter case nitrogen or other non- oxidizing gas may be passed through the tube and directed on to the wire by the perforations 25. In a modified form the wire &c. passes through the tube, which is heated by an external resister.
