ABSTRACT:
The present invention relates to a fluid conditioning system having a primary distribution channel configured to distribute coating fluid transversely. Fluid from the primary distribution channel is carried by a second conduit to a secondary distribution channel which is configured to minimize transverse pressure gradients in fluids having Reynolds Numbers of up to 50 without substantial formation of eddies. A product conduit withdraws liquid from the secondary distribution channel. This fluid conditioning system is particularly useful in applying photographic liquids to a web of photographic film or paper. For this utility, the system can be incorporated in a conventional slide hopper between adjacent layering plates or the liquid-applying plate and its adjacent layering plate.
