Abstract: A B S T R A C T           This invention relates to the art of coating glassware while the ware is moving through an annealing lehr which is pro-vided with a cooling section near the exit end of the lehr.  The cooling section is of the continuous recirculation type provid-ing an arrangement for generally cooling the ware to a relatively even temperature even though  the ware is moving through the lehr in multiple rows and columns.  The ware is moved through the lehr on a belt which is formed as a webbed belt and constitutes a foraminous conveyor.  A lubricious material in the form of a vapor or mist of an organic, non-metallic coating material selected from the group consisting of polyolefins, fatty acids and their derivatives is injected into the recirculating cooling air in the cooling section of the lehr to thereby form a durable lubricious coating on the exterior surfaces of the glass article. The articles, at the time they are passed through the cooling section, will be at a temperature between 200°F. and 400°F. The vapor generator used to form the vapor or mist has an outlet tube of at least one foot in length extending vertically from the generating chamber to avoid injection of any condensate into the cooling section of the lehr.

Abstract: ABSTRACT OF THE DISCLOSURE         Oven exhaust gases containing exothermically oxidizable solvent vapours are withdrawn from a strip sheet metal coating oven by a constant volume rate fan or blower disposed downstream of a heat exchanger in turn receiving high temperature gases from an incinerator in which the oven gases are incinerated so that the mass rate at which the gases are extracted from such an oven is essentially independent of the oven gas temperature. The gases are extracted from the oven into a novel incinerator comprising a housing within which an elongated incinerator tube is supported in inwardly spaced disposition relative to such housing and which receives solvent-laden gases from that housing for incineration in such tube.  The oven gases within the housing and surrounding the incinerator tube effectively provide thermal insulation and so avoid the need for the use of absorbent insulation material within and around the incinerator tube.  A negative pressure created within the housing and ducts reduces the risk of fire in the event that the incinerator is temporarily extinguished, and reduces leaks.
