Abstract
Abstract An apparatus for vapor coating glass articles where the coating is applied to heated glass articles being carried on a moving conveyor. The apparatus includes a vapor generating cabinet and a connected fuming or vapor coating tunnel which directs the vapor onto the surfaces of the moving glass articles. The vapor is reduced by the heat of the articles to a protective film such as a metallic oxide. The coating tunnel includes means for directing the vapor onto the moving articles and means at opposite ends of the tunnel for both exhausting excess vapor and for forming vapor confining and moisture excluding air curtains.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
150 words
In a cabinet vaporizer for continuously converting a liquid container coating formulation to a dry air and gas vapor mixture for application to the surfaces of articles and including a bubbler tank with a liquid inlet and a vapor outlet for exposing a supply of the liquid formulation to vapor forming air bubbles rising through the formulation from a submerged air bubbler tube and including a mixer for combining the vapor with dry air in predetermined proportions, the improvement comprising an enclosed hollow outer cabinet completely surrounding said vaporizing chamber means and the adjacent portions of the formulation tank feeding conduits and the bubbler tube air conduit and the vapor outlet conduit and the mixer, means for maintaining the air atmosphere within said cabinet and surrouNding said chamber means and said mixer and said conduits at a constant temperature comprising an air recirculating means including a thermostatically controlled tunnel heater.
Claim 2
Dependent Claim
