摘要:
A method for processing a photographic material can be carried out by surface application (40). A device for processing a silver halide photographic material comprises a means (50) for measuring the surface temperature of the material. This device affords more efficient and more reproducible processing.
摘要:
A method for reforming the surface of a photographic emulsion layer. In the method, the surface of the emulsion layer is dried to at least sensible dryness. Water is then deposited onto the surface of the emulsion layer. The depositing is substantially uniform and in an amount that is less than about 0.074 grams of water per square meter (0.80 grams of water per square foot) of emulsion layer.

A coating device is disclosed which is provided with a first side bar, which extends along a transverse direction of a conveyance plane, which is a conveyance path of a belt body, and a second side bar, which is located at a downstream side of the first side bar. Also provided are a channel, which supplies a liquid at an upstream side of the first side bar, and a liquid-pooling section, which accumulates the liquid during coating of the liquid and is located between the first side bar and the second side bar. Also disclosed is a method which uses this coating device to coat a liquid on a belt body which is conveyed at high speed.
摘要:
An apparatus for washing contaminants from a coated surface of a material comprises an inclined substantially planar surface up which the material is passed, an inlet for the introduction of wash solution at the upper part of the planar surface and pressure applying means for holding the material in full contact with the surface.
摘要:
A process for forming a photographic image includes a colour development step and a bleach step, a redox amplification step separate from the colour development step, the amplification step and the bleach step take place in a single processing solution and wherein
(i) the bleach amplifier solution contains hydrogen peroxide or a compound which releases hydrogen peroxide during processing and (ii) the bleach amplification step is effected by applying to the surface of the photographic paper or other material an amount of bleach amplifier solution in the range from 20 to 500 ml/sq metre, preferably 30 to 70 ml/sq metre, and wherein the solution applied to the surface is used once only.
The invention also comprises an apparatus for use in the bleach amplification of photographic paper or other material comprising
(i) a pair of generally parallel closely spaced apart sheets (ii) means for feeding the photographic paper between the sheets and (iii) means for feeding bleach amplifier solution to the space between the sheets.
The gap between the sheets is preferably such that in use they are held together by the surface tension of the bleach amplifier solution.
摘要:
Die Erfindung betrifft ein Verfahren zum Zuführen von Tonermaterial an mehrere Entwicklerstationen, bei dem in einer ersten Betriebsphase durch einen Luftstrom Tonermaterial (12) aus einem Tonerbehälter (16) angesaugt und einem ersten Zwischenspeicher (28a) einer ersten Entwicklerstation (14a) zugeführt wird. In einer zweiten Betriebsphase wird durch einen Luftstrom Tonermaterial (12) aus dem Tonerbehälter (16) einem zweiten Zwischenspeicher (14b) einer zweiten Entwicklerstation (28b) zugeführt. Ferner wird in einer dritten Betriebsphase auf einem Filtermittel (50) abgelagertes Tonermaterial (12) von diesem entfernt. In der ersten und zweiten Betriebsphase wird das mit den Zwischenspeichern verbundene Filtermittel (50) in einer ersten Richtung durchströmt, während in der dritten Betriebsphase das Filtermittel (50) in einer zur ersten Richtung im Wesentlichen entgegengesetzten zweiten Richtung von Luft durchströmt wird.
摘要:
The invention relates to a device and a method for dosing toner material (12) in an electrophotographic printer or copier, in addition to a method and a device for separating toner material (12) and air. A bucket wheel (78) comprising buckets (62, 64) is rotatably mounted underneath a toner container (28). Toner material (12) drops from the toner container (28) into at least one bucket chamber (66). The bucket wheel (78) is rotated by a drive, whereby the toner material (12) in the bucket chamber (66) is transported to a region underneath the rotational axis during a rotation. The invention also relates to a method and a device for separating toner material (12) and air from a toner material-air mixture, in addition to a method for supplying toner material (12) to several developer stations (14a, 14b).
摘要:
A method and apparatus for developing a strip of photosensitive media (13) having image exposure area having an undeveloped exposed portion thereon. The apparatus includes a transport mechanism for moving the photosensitive media along a processing path (34); and a mechanism positioned along the processing path for selectively applying a coating of the processing solution only on the undeveloped exposed portion of the strip of photosensitive media. The apparatus further includes sensors (39) for determining the location of the undeveloped exposed portion of the image exposure area. A scanner (40) may be provided for scanning the strip of photosensitive media so as to obtain a digital record of the images developed thereon.
