Abstract
Abstract A guide member which guides a sheet of photographic print paper to a position between two juxtapositioned rotating rollers which move the sheet of paper through a liquid. The guide member has a part provided with spaced-apart portions which permit circulation of the liquid. The spaced-apart portions have converging surfaces so that they do not restrain the movement of the sheet of paper.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
149 words
In photographic processing apparatus having a circulating liquid therewithin, a pair of rotatable elongate parallel juxtapositioned rollers for moving a flexible sheet therebetween as the sheet moves in a given direction of travel, the sheet having at least one curled corner, a pair of guide members positioned adjacent the rollers, each of the guide members having a generally flat surface directed toward the rollers so that a flexible sheet is movable between the guide members to a position between the rollers, each guide member including a plurality of longitudinally arranged teeth, each of the teeth having converging surfaces extending generally toward the rollers so that a curled corner of the sheet which engages the guide member is not restrained thereby, and so that the curled corner is moved between the rollers without folding of the corner, said teeth defining therebetween passages to permit circulation of liquid within the apparatus.
Claim 2
Dependent Claim
149 words
In photographic processing apparatus having a circulating liquid therewithin, a pair of rotatable elongate parallel juxtapositioned rollers for moving a flexible sheet therebetween as the sheet moves in a given direction of travel, the sheet having at least one curled corner, a pair of guide members positioned adjacent the rollers, each of the guide members having a generally flat surface directed toward the rollers so that a flexible sheet is movable between the guide members to a position between the rollers, each guide member including a plurality of longitudinally arranged teeth, each of the teeth having converging surfaces extending generally toward the rollers so that a curled corner of the sheet which engages the guide member is not restrained thereby, and so that the curled corner is moved between the rollers without folding of the corner, said teeth defining therebetween passages to permit circulation of liquid within the apparatus.
Claim 3
Dependent Claim
127 words
In apparatus for movement of sheets of photographic print paper through a circulating liquid, a pair of elongate cylindrical juxtapositioned roller members rotatable about substantially parallel axes, the roller members being adapted to rotate together to cause travel of sheets of print paper which move in seriatim relationship between the roller members, the improvement comprising a pair of elongate guide members positioned in adjacent converging relationship one to the other, the guide members being adjacent the roller members and substantially parallel thereto, each guide member being provided with a longitudinal portion having a plurality of converging protuberances extending generally toward the roller members, the space between adjacent protuberances serving as passages for movement of liquid which engages the sheets and the guide members and the roller members.
Claim 4
Dependent Claim
127 words
In apparatus for movement of sheets of photographic print paper through a circulating liquid, a pair of elongate cylindrical juxtapositioned roller members rotatable about substantially parallel axes, the roller members being adapted to rotate together to cause travel of sheets of print paper which move in seriatim relationship between the roller members, the improvement comprising a pair of elongate guide members positioned in adjacent converging relationship one to the other, the guide members being adjacent the roller members and substantially parallel thereto, each guide member being provided with a longitudinal portion having a plurality of converging protuberances extending generally toward the roller members, the space between adjacent protuberances serving as passages for movement of liquid which engages the sheets and the guide members and the roller members.
Claim 5
Dependent Claim
89 words
The apparatus of claim 2 in which the paper guide means includes an elongate member having a longitudinal axis which is substantially parallel to the axes of rotation of the roller members, the elongate member having a longitudinal portion adjacent the roller members, said longitudinal portion having a plurality of teeth extending generally toward the roller members, each of the teeth having opposed edge surfaces which converge in a direction generally toward the roller members, the edge surfaces being generally normal to the lOngitudinal axis of the elongate member.
Claim 6
Dependent Claim
15 words
The apparatus of claim 3 in which each of the edge surfaces is substantially planar.
Claim 7
Dependent Claim
125 words
A guide member adapted to be mounted within a liquid container for directing a flexible sheet between a pair of adjacent feed rolls, said guide member comprising an elongate body having a longitudinally extending continuous edge portion defining a generally flat surface, a plurality of longitudinally spaced teeth projecting in only one direction from said edge portion and defining therebetween a plurality of passages to permit circulation of liquid within the container, each of the teeth being substantially ''''V'''' -shaped, and means for mounting said guide member within the container with said teeth projecting generally toward the feed rolls to prevent a curled corner of the sheet from being restrained by said elongate body as the sheet is urged to move toward the feed rolls.
Claim 8
Dependent Claim
125 words
A guide member adapted to be mounted within a liquid container for directing a flexible sheet between a pair of adjacent feed rolls, said guide member comprising an elongate body having a longitudinally extending continuous edge portion defining a generally flat surface, a plurality of longitudinally spaced teeth projecting in only one direction from said edge portion and defining therebetween a plurality of passages to permit circulation of liquid within the container, each of the teeth being substantially ''''V'''' -shaped, and means for mounting said guide member within the container with said teeth projecting generally toward the feed rolls to prevent a curled corner of the sheet from being restrained by said elongate body as the sheet is urged to move toward the feed rolls.
