Section of RADIO DAILY. Friday. Dec. 30. 1949 New TV Tube Coaling Revealed By Corning A new method for coating the inside surface of TV picture tubes has been announced by John L. Ward, manager of Corning Glass Works' electrical products division. This method, a laboratory development of a new electrically conductive opaque coating, can be applied at the time of manufacture of the glass bulb and eliminates the need for carbon coating of the bulb by laborious hand methods in TV tube manufacturing plants. Permanently Fused To Surface Also, because the bulbs can be coated by Corning Glass Works at the time of manufacture, this operation will be eliminated at the tubemaker's plant. In addition, the new coating is permanently fused to the surface of the glass and will not be affected by washing or other reclaiming operations. Ward also stated that this is a completely new type of coating with all the desirable features of the presently-used carbon coating su?h as non-reflectivity and opacity. As soon as facilities for commercial production are available, the company plans to coat all its glass TV tubes with the new material. Ease of applying the new coating. Ward pointed out, will simplify the final assembly of the new rectangular all-glass tube and speed its adoption by the TV industry. EHGIREEBS — COHSII LTR nTS RALPH B.
