Abstract: A wire hanger assembly includes a hook member with at least three wire members depending therefrom, which wire members are specially designed for quick attachment to and release from a compatibly designed container. Each wire includes an enlarged protuberant end portion and the rim of the hanging container includes a plurality of substantially T-shaped slots therein. Each protuberance is inserted through the cross portion of one of the T-slots, and then the wire portion above the protuberance is slipped back to a position where the protuberance is seated in a cavity from which it cannot inadvertently slip.

Abstract: A bubbler assembly comprising a bubbler tube having a sleeve surrounding at least a portion thereof to define an annular space therebetween. A corrosion-inhibiting gas is introduced into the space to minimize oxidation and alkali-sulfate corrosion of the bubbler tube, or preferably the gas is moved through the space to purge the space of oxygen and alkali-sulfate corrosives, when the bubbler assembly is mounted within a mounting hole provided through a refractory wall, e.g. the bottom, of a glassmaking furnace.The bubbler assembly alternatively comprises a bubbler tube, a fluid coolant jacket mounted within the refractory wall mounting hole, and facilities for facilitating movement of the bubbler tube relative to the refractory wall, independently of the fluid coolant jacket.

Abstract: In a glass melting furnace, the beneficial effects of passing molten glass streams through the intensified heating at the surface of the "spring zone" are enhanced by the use of bubblers. In one aspect, the rate of bubbling is greater near a side wall of the furnace than in the center immediately upstream of the spring zone so as to direct side portions of the throughput stream into the spring zone. In another aspect of the invention, the rising currents of the spring zone are enhanced by bubbling a stream entering the spring zone at a first elevation and then bubbling the same stream portion at a higher elevation.
