Linear Phasolver Measuring 4iglne
The heart of the Phasolver Is the driver pattern to be

to be laid down on a parallel glass plate.

achieving the S mioron accuracy. it is a sinusoidal
pattern similar to the one used in their rotary

The opera&ingmodel of the liquid gate worked beautifully.
To eliminate bubbles going across. the gate, they are
building a low meatin pressure, high volume slow acting

They are greatly goncerned about operator convenience
in changing spools and are working hard an this aspect.
It is difficult because the spools are enclosed in the
liquid chamber and the rollers and gate are submerged.
