Abstract
217,212. Strasser, A., and Graber, O. June 6, 1923, [Convention date]. Heat-storing apparatus.- An electric heater comprises a resistance a embedded in an oxide of the rare earths such as zirconium oxide, contained in a quartz casing b hermetically sealed in a metal body c serving as a heat accumulator. The sides of the metal body may be ribbed to increase the heating surface. In a modification, the quartz tube is arranged in spiral form in the wall of a hollow cylindrical metal body. The conductivity of the oxide increases as the temperature rises so that the oxide co-operates with the resistance to produce the heating effect.
