Total Claims: 5
Claim 1
Independent Claim
146 words
An improved film processor tank for receiving film, paper and the like therein, the tank mounted in a film processor unit for receiving a fluid such as film processing chemicals or dryer air, the tank comprising: a tank housing integrally formed and having a round bottom and an overflow port in the side thereof; and a hollow tank divider disposed along the length of the tank and slidably received therein, the divider having a concave idle roller mounted on the bottom thereof, the divider having an inlet port in the top thereof for receiving the fluid and apertures along the length thereof for discharging the fluid into the tank housing adjacent the film as it is transported thereby, the opposite sides of the divider concave in shape for limiting the contact of the film against the sides of the divider as the film is transported thereby.
