Abstract: Continuous bath or curtain processes for the thermal deposition of a coating from a coating solution onto a moving metal web are used to apply a coating onto the web. The compositions that result from the processes are substantially free of defects relative to batch processes. The continuous process is particularly applicable for priming zinc and zinc-alloy coated steel webs.

Abstract: A sensor probe device for monitoring atmosphere within a chamber. The device includes a housing that extends through a wall of the chamber being monitored, and a tubular sleeve that is movably captured within the housing. The sleeve includes an open end for receiving a sensor probe, and a closed end having a plurality of radially spaced apertures that extend through the sleeve wall. The apertures provide an open ribbed portion that exposes the enclosed sensor probe to chamber atmosphere when the sleeve portion is inserted into the chamber. A drive mechanism is attached to either extend the open ribbed portion of the sleeve outward from its shielded position within the housing to an extended position within the chamber, or retract the sleeve portion from the chamber back into its shielded position within the housing.
