Abstract
An atmosphere controlled workpiece heating chamber includes a spaced apart multiple gas flow means combination which avoids contamination of the atmosphere within the chamber from ambient atmosphere such as air. In one form, the chamber includes a gas diffuser as one flow means, and a heating means, both of which are readily removable, and easily and accurately replaceable.
