Abstract
18,231. Bachmann, J. F., Vogt, A., Weiner, C. C., K÷nig, A., Kirchner, J., and J÷rg, A. Aug. 24 Soldering; metals, working by electricity.- Soldering-irons are electrically heated by enclosed resistances, made by moulding and firing mixtures of carbon or divided metal with non-conductors such as clay or porcelain, as described in Specifications No. 15,238, A.D. 1897, and No. 18,156, A.D. 1898. The resistances are insulated by air, or by glazing or enamelling, or by heating electrically to whiteness so that the carbon on the surface burns out, after which the surface is coated with solution of aluminium sulphate or other suitable material, and heated. Fig. 3 shows a soldering-iron f, which contains the cylindrical resistance a, provided with connecting-rings on its ends, and with a metal screw h for short-circuiting more or less of it to regulate the temperature. The insulating-coating may be on the inner surface of the iron.
