Abstract
Apparatus for distributing processing fluid across a sheet of photographic material to facilitate the distribution of the fluid between that sheet and another sheet. The processing fluid is contained in one or more elongated flexible tubes, each provided at one end with a flow control nozzle and provided with flow control stops spaced by a predetermined length of the tubing to facilitate deposition of the fluid in a defined path across the sheet.
Claims4
A photographic fluid applicator adapted to cooperate with an extrusion press for dispensing a predetermined quantity of processing fluid across a sheet of photographic material, said applicator comprising an elongated flexible tube, a quantity of processing fluid greater than said predetermined quantity in said tube, a plug in a first end of said tube, said plug closing said tube and forming a stop preventing collapse of said tube when said tube is engaged by an extrusion press in a first region adjacent said first end, means forming a flow limiting orifice in a second end of said tube opposite said first end, means detachably mounted in said orifice for preventing the flow of processing fluid until detached, and stop means mounted in said tube intermediate said ends and spaced therefrom for preventing collapse of said tube by an extrusion press in a second region adjacent said second end to stop the flow of fluid from said tube when engaged by the press as said tube is drawn through the press from said first end toward said second end.
A photographic fluid applicator for dispensing a predetermined quantity of photographic processing fluid in a path across a sheet of photographic material, comprising an elongated tube of flexible material, means closing one end of said tube, means forming a metering orifice in the other end of said tube, a rigid ferrule in said tube intermediate and spaced from said ends, and a quantity of processing fluid in said tube greater than said predetermined quantity.
A photographic fluid applicator adapted to cooperate with an extrusion press for dispensing a predetermined quantity of processing fluid across a sheet of photographic material, said applicator comprising an elongated flexible tube, a quantity of processing fluid greater than said predetermined quantity in said tube, a plug in a first end of said tube, said plug closing said tube and forming a stop preventing collapse of said tube when said tube is engaged by an extrusion press in a first region adjacent said first end, and stop means mounted in said tube intermediate said first end and a second end opposite said first end and being spaced from said ends for preventing collapse of said tube by an extrusion press in a second region adjacent said second end to stop the flow of fluid from said tube when engaged by the press as said tube is drawn through the press from said first end toward said second end.
A photographic fluid applicator for dispensing a predetermined quantity of photographic processing fluid in a path across a sheet of photographic material, comprising an elongated tube of flexible material, means closing a first end of said tube and forming a stop preventing collapse of said tube at said first end, detachable means closing the other end of said tube, a rigid ferrule in said tube intermediate and spaced from said ends, and a quantity of photographic processing fluid in said tube greater than said predetermined quantity, in which the amount of said fluid between said first end and said ferrule is substantially equal to said predetermined quantity.
