Claim 1
Independent Claim
210 words
In a developing apparatus of the type comprised of a plurality of successive processing chambers arranged for generally horizontal travel of a photographic material to be developed through the successive processing chambers, with each processing chamber being provided with a processing-fluid tank and guide means for guiding photographic material through the processing chamber, and with transport roller pairs being provided intermediate adjoining processing chambers for transporting photographic material from one chamber to the next, with the last processing chamber being a washing chamber, a washing chamber of novel construction comprising a wash-water tank containing a body of wash water with the upper surface of the body of wash water maintained at a predetermined level; guide means for guiding photographic material through the washing chamber, including submerging means for causing transported photographic material to pass below the upper surface of the body of wash water; a pair of outfeed rollers at the outlet end of the washing chamber for outfeed of washed photographic material, one roller being arranged above the other; and a spray pipe located intermediate the submerging means and the outfeed rollers and provided with a plurality of spray outlets oriented for spraying wash water onto the peripheral surface of the upper one of the pair of outfeed rollers.

In a developing apparatus of the type comprised of a plurality of successive processing chambers arranged for generally horizontal travel of a photographic material to be developed through the successive processing chambers, with each processing chamber being provided with a processing-fluid tank and guide means for guiding photographic material through the processing chamber, and with transport roller pairs being provided intermediate adjoining processing chambers for transporting photographic material from one chamber to the next, with the last processing chamber being a washing chamber, a washing chamber of novel construction comprising a wash-water tank containing a body of wash water with the upper surface of the body of wash water maintained at a predetermined level; guide means for guiding photographic material through the washing chamber, including submerging means for causing transported photographic material to pass below the upper surface of the body of wash water; a pair of outfeed rollers at the outlet end of the washing chamber for outfeed of washed photographic material, one roller being arranged above the other; and a spray pipe located intermediate the submerging means and the outfeed rollers and provided with a plurality of spray outlets oriented for spraying wash water onto the peripheral surface of the upper one of the pair of outfeed rollers.
Claim 3
Dependent Claim
91 words
The developing apparatus defined in claim 1, further including a second spray pipe located in the region of the submerging means and provided with at least one spray outlet for downward discharge of spray water, and a deflecting vane mounted in the washing chamber, the orientations of the at least one spray outlet of the second spray pipe and of the deflecting vane being such that wash water is sprayed out the former onto the latter and deflected along the deflecting vane to the middle of the body of wash water.
Claim 4
Dependent Claim
40 words
The developing apparatus defined in claim 2, the deflecting vane having an upper end mounted in the washing chamber and a lower end so configured as to extend generally horizontally into the upper surface of the body of wash water.
Claim 5
Dependent Claim
27 words
The developing apparatus defined in claim 2, the washing chamber including an upper part, the two spray pipes and the upper part being integral with one another.
Claim 6
Dependent Claim
64 words
The developing apparatus defined in claim 1, further including a stripping lip structure located in the vicinity of the pair of outfeed rollers upstream thereof, the stripping lip structure extending in the axial direction of the rollers over the full length of the upper roller and operative for stripping contaminated wash water off the surface of photographic material being transported towards the outfeed rollers.
Claim 7
Dependent Claim
55 words
The developing apparatus defined in claim 5, the guide means being operative for establishing a path of transport for photographic material transported through the washing chamber such that the transported photographic material in conjunction with the stripping lip structure forms a channel for the wash water sprayed onto and running off the upper outfeed roller.
