Abstract
A system for uniformly dispensing a frit material onto the seal edge of a CRT funnel includes a motor for rotating the funnel. The motor also drives a pulse generator which provides a selected number of input pulses for each increment of rotation. The input pulses are provided to two programmable BCD counters. One counter controls the funnel motor and is programmed to change the motor speed around the funnel corners. The other counter controls the feed screw dispenser and is programmed to maintain the ratio of motor speeds within a selected range of values.
