摘要： SUBSTANCES ARE MIXED INTO LIQUID FLOWING VISCOUSLY IN A CHANNEL OR PASSAGE BY MEANS OF GAS-CURTAIN MIXER DEVICES OF THE KIND TAUGHT IN BRITISH PAT. NO. 1,171,133. TWO SUCH DEVICES ARE USED, EXTENDING TRANSVERSELY OF THE CHANNEL OR PASSAGE AND AT AN ANGLE OF 10 TO 80 DEGREES WITH RESPECT TO THE FLOW OF LIQUID. THE UPSTREAM MIXER DEVICE EXTENDS ONLY ABOUT 88 TO 98.5 PERCENT OF THE WAY ACROSS THE PASSAGE OR CHANNEL; THE DOWNSTREAM MIXER DEVICE EXTENDS ALL THE WAY ACROSS THE CHANNEL. THIS YIELDS AN IMPROVED MIXING ACTION. THE FOREGOING CONCEPT IS APPLIED TO THE MIXING OF COLORANT INTO MOLTEN GLASS TRAVELING IN THE FOREHEARTH OF A CONTAINER-GLASS TANK. THIS REQUIRES PARTICULAR CONDITIONS OF THE USE OF THE MIXER DEVICES WITH RESPECT TO GAS-IMPINGEMENT ANGLE, SPACING BETWEEN THE DEVICES, AND ORIENTATION ANGLE OF THE DEVICES WITH RESPECT TO THE FLOW OF THE GLASS.
