^ HOW KINESCOPES are made Manufacturing process begins with inspection of all parts comprising tfie tube, whether glass or metal-shell type. Metal tubes are placed on a crawling conveyor belt to permit the phosphor to settle on the face-plate. At the end of the settling belt, auto- matic machinery tips the tube and decants the remaining liquid. Kinescopes are baked in huge ovei to "boil" out impurities and to dry thi inside graphite coating. e|( As a tube approaches completion it is tested for picture brightness under home lighting conditions. Final tests are made to insure tha* the tube will give a well-centered perfectly-focused picture. After the tube has passed all tests '\ is given its final washing before pain is applied to the outside.
