Abstract
Apparatus is described for treating substances carried or affixed to a surface of a continuous substrate, e.g., a ribbon or tape, with successive treating fluids including liquids contained in a series of treating chambers, adjacent chambers being separated by a high surface tension liquid, e.g., mercury. The chambers may be defined by hollow walls having slots located below the level of the treating fluids in the adjacent treating chambers, such slots being dimensioned to allow passage of the tape between the adjacent treating chambers and to prevent dislocation of the high-surface tension liquid, which is located in the hollow walls and serves to wipe excess treating fluid from the tape during passage between the adjacent treating chambers, so as to prevent carryover therebetween.
