Glass toughening quench system

The air quench system described is a system to provide large volumes of high velocity air directed onto the surfaces of sheet glass to rapidly cool and thus toughen the glass. This is achieved by the use of specially designed compressed air ejectors fitted in manifolds. Compressed air escapes at very high velocity into the throat of the nozzles, and draws into the nozzle cap a much larger volume of atmospheric air. This provides the high volume of quenching air directed onto the glass surfaces.
