Claim 3
Dependent Claim
116 words
The apparatus claimed in claim 1, further including: at least a first and a second slot nozzle coupled to said circulating means and forming a portion of said channel for controlling the velocity and amount of processing solution that dynamically impinges on the surface of the photosensitive material; a first conduit that is connected to one end of said first slot nozzle and said circulating means so that processing solution may travel in said first slot nozzle in a first direction; and a second conduit that is connected to the other end of said second slot nozzle and said circulation means so that processing solution may travel in said second slot nozzle in a second direction.
Claim 4
Dependent Claim
31 words
The apparatus claimed in claim 1, wherein the inner textured surfaces of said channel are canted to allow the processing solution to travel in a different direction than the photosensitive material.

Claim 7
Dependent Claim
20 words
The apparatus claimed in claim 5, further including a heat exchanger that rapidly regulates the temperature of the processing solution.
Claim 8
Dependent Claim
42 words
The apparatus claimed in claim 6, further including: a plurality of metering pumps for metering specified amounts of chemicals; and a manifold coupled to said first and second conduit and said metering pumps for dispensing additional processing solution to the small volume.
