METHOD FOR REPROCESSING VIDEO TUBES

摘要

Picture tubes are reprocessed by heating the picture tube to at least the fusing temperature of the solder at the joint and separating the screen and the cone under the influence of gravity. This method effects a clean separation of the screen and the cone by slowly heating the aerated picture tube which is arranged, during heating, in such a way that the joint between the screen and the cone is inclined with respect to the horizontal, and displacing the screen and the cone in opposite directions.
