摘要:
The present invention relates to a method and apparatus of applying a solution of a predetermined viscosity to photosensitive material to form a protective coating on the photosensitive material. The method and apparatus can be used in a photographic processing device, and the apparatus can be built into an existing or new photographic processor or added on as an accessory. The method and apparatus is utilized to apply a viscous solution to at least one surface of processed photosensitize materials prior to drying in a manner that allows the solution to be uniformly applied to the at least one surface at a specific layer thickness. The viscous solution after drying functions as a protective coating which can protect the processed photosensitize material against scratches and moisture. The apparatus includes a control mechanism which controls the thickness, uniformity and laydown amount of the applied viscous solution so as to insure that a uniform coating that provides protection to the entire surface of the processed photosensitize material is provided.

The present invention relates to a coating apparatus having a removable coating module for applying a protective coating to at least one surface of a photosensitive material. The coating apparatus can be a stand-alone unit and can be added to an existing or new photographic processor. The coating product can be a solution having a predetermined viscosity which is applied to at least one surface of the photosensitive material prior to drying in a manner that allows the solution to be uniformly applied to the at least one surface at a specific layer thickness. The viscous solution after drying functions as a protective coating which can protect the processed photosensitive material against scratches and moisture. The removable coating module facilitates maintenance and cleaning after the viscous solution has been consumed. The apparatus includes a control mechanism which controls the thickness, uniformity and laydown amount of the applied viscous solution so as to insure that a uniform coating that provides protection to the entire surface of the photosensitive material is provided.
摘要:
A photographic processing apparatus including recirculation of processing solution is provided with a variable loop additive control system comprising a treatment container in which additive solids, pastes or fluids are introduced and through which a controlled volume of processing solution is circulated from and back to the recirculating system loop. The secondary loop of the additive system allows control of the flow of processing solution through the treatment container so that the mixing of the additive into the processing solution may be controlled at a desired rate and the additive is not excessively utilized or dissipated. Various arrangements for connecting a secondary additive loop to the primary loop of a recirculating processing solution system are illustrated.
摘要:
An apparatus for processing photosensitive materials, which comprises: a tank through which a processing solution flows; a rack having integral means to facilitate its insertion and removal from the tank, the rack and the tank are relatively dimensioned so that a small volume for holding processing solution and photosensitive material is formed between the rack and the tank; means for circulating the processing solution through the small volume; and means coupled to the rack for moving the photosensitive material through the small volume.
摘要:
Textured surfaces on respective walls of racks and tanks of photographic processing apparatus reduce the frictional forces between the photosensitive material leading edge surfaces and the walls of the racks and tanks. The processing solution flows through fissures in the textured surfaces, thereby providing a solution bearing layer between the photosensitive material and the textured surfaces. This allows a greater photosensitive material leading edge impact angle with the textured walls which allows the photosensitive material to change direction unimpeded.

摘要:
A low volume photographic material processing apparatus that utilizes a narrow horizontal processing channel with an upturned entrance and exit to contain processing solution within the channel. The channel is formed by a repeating combination of squeegee pinch rollers and impingement slot nozzles. Photographic processing solution is introduced through the impingement slot nozzles and the squeegee pinch rollers are used to remove the processing solution from the photosensitive material and provide transport of the photosensitive material. Solution level control is achieved by drains positioned below the tops of the upturned sections.
