Abstract
283,144. Bosch Akt.-Ges., R. Jan, 5, 1927, [Convention date]. Condensers are made according to a process which consists in first impregnating with sulphur, and then while the mass is still liquid, immersing the whole in an insulating substance in a liquid state and having a low melting-point, for instance montan wax, By this means air cavities are prevented from forming as the sulphur solidifies.
