APPARATUS FOR DISSIPATING FOAM ON MOLTEN GLASS

摘要

A method and apparatus for dissipating foam from the surface of a pool of molten material, such as glass. A pulse of compressed gas is periodically directed at the surface of the pool of molten material. The pulse of gas is periodically supplied at a frequency rate, at a pressure and for a time interval sufficient to keep the surface substantially free of foam. The gas is supplied through a valve that may be periodically opened and closed. This invention may be used in conjunction with a bubble-type depth gauge.
