Abstract

232,257. British Thomson-Houston Co., Ltd., (Assignees of Hollnagel, H. P.). April 11, 1934, [Convention date]. Cleaning; tinning.-Insulation is removed from electric conductors by means of a bath of melted caustic alkali. The process is applicable either to removing insulation from long lengths of conductor on account of defects or for other reasons, or to baring small portions to facilitate making joints. In the apparatus shown in Fig. 1, the conductor is drawn through a bath of alkali 7 maintained at a temperature rather under 700‹ C. by an electric heater 10, through a washing tank 8, in which is a felt wiper, and between wire brushes 18, 19. The bare wire, which has been somewhat stretched and softened in the process, is passed through a die 22 to harden it and reduce it to a standard size. To bare ends &c. of conductors, they are dipped into a jacketed pot 25 heated by an electric heater 26. A shield 28 is placed above the surface of the molten alkali, and an air blast from a pipe 29 checks charring of insulation which is not to be removed. To prevent insulation of cotton, silk, &c. from unravelling, a portion of the conductor overlapping that to be bared is impregnated with shellac and baked before treatment. The bared ends may be tinned by dipping into an electrically-heated vessel 30 containing solder with a layer of molten caustic soda on the surface.
