Abstract

809,668. Electric discharge tubes. STANDARD TELEPHONES & CABLES Ltd. July 13, 1956, No. 21800/56. Class 39(1). The inner surface of the envelope of air electric discharge tube is coated with titanium dioxide, to reduce secondary emission. The coating is applied in a suitable binder, e.g. a suspension of 300 gms. of titanium dioxide in a mixture of 200 millilitres of a butyl acetate and 100 millilitres of a butyl alcohol may be mixed with a polymethacrylic ester binder dissolved in xylene. Preferably the coating is sprayed on and air-dried at 120‹C.
