Abstract
586,209. Electric heating. HENLEY'S TELEGRAPH WORKS CO., Ltd., W. T., and MACDONALD, H. A. Sept. 5, 1944, No. 16916. [Class 39 (iii)] Apparatus for heat treating a non-conductive covering of an electric wire passing therethrough, comprises a first part in which the covering is heated to the treatment temperature in a short period of time by the dielectric loss method, and a second part in which this temperature is maintained for a relatively long period of time by some other method of heating. As shown in the drawing, two tubular electrodes 3, 4 and a tubular chamber 10, e.g., of metal, forming the first and second heating chambers respectively, and the nozzle 16 of an extrusion machine, are axially aligned and separated by short insulating tubes 5, 11, 15. The electrodes 3, 4 are housed in a tubular screen 7 and connected to a high frequency electric source 9. The chamber 10 is heated by the passage of a heavy current from a source 13. An earthed wire 1, emerging from the nozzle 16 with a covering 2, e.g., of natural or synthetic rubber, passes with a small clearance through the aligned members and may be supported at intervals, as by a roller 19 housed in a pocket in the chamber 10. This chamber has an end piece 18 which may constitute a sealing gland for treatments at high pressures. The second heating chamber may be from five to fifteen times the length of the first and may be heated by other means. For example, it may be flooded with, or surrounded by, a heated vapour, or it may be heated by gas flames. It may also be compacted to offer an extended path to the covered wire, such as a helix comprising a number of turns. Specification 554,854 is referred to.
