System and method for controlling the specific gravity and viscosity of the slurry applied to television picture tube faceplates

摘要: A system and method for continuously maintaining the specific gravity viscosity of slurry applied to a television picture tube includes container dispensing faceplate such receiving excess from faceplate. The level in is held constant by addition materials container. first added material has greater than that dispensed second which quantity third determined corrections required bring parameters preselected values. By adding three dispenser accordance with error signals representative parameters, gravity, are within specified limits.
