Abstract: A coating hood for applying coating fluid to vitreous articles such as bottles or the like. Coating fluid is applied through a plurality of coating manifolds within the hood, and these manifolds on opposite sides of the hood are offset with respect to each other so as to avoid creating a zone of fluid stagnation within the hood.

Abstract: An improved system for applying internal treatment gas in the manufacture of glassware such as bottles or the like. An independent primary treatment system and backup treatment system are disclosed, with each treatment system monitoring itself to detect malfunctions. The backup system is automatically actuated whenever the primary system malfunctions. Simultaneous malfunctions of both systems cause glassware to be rejected from the conveyor line for a predetermined period, producing a gap which pinpoints the arrival of possibly untreated ware.
