Abstract

296,707. Voigt &. Haeffner Akt.-Ges. Sept. 5, 1927, [Convention date]. Moulding electric hot-pastes.-A spring - supported mould ring b is partly filled with refractory insulating material f in powdered form. A spiral or otherwise shaped heating resistance g is embedded therein by pressure applied by a tool h conforming in shape to that of the resistance. The tool is then removed and more insulating material added, Fig. 3, with, if desired, a metal top plate n, Fig. 5, and pressure is again applied to consolidate the whole mass of material. In order to maintain pressure on the undisturbed part of the surface of the powdered material in the preliminary pressing operation the pressing tool h h carries a complementary portion i which receives pressure from the central ram l through a spring k.
