摘要： It is known to use rotating drums in photographic processing apparatus. However, in many embodiments, relatively large volumes of processing solution are required for effective operation of the apparatus. This makes most drum arrangements unsuitable for use with unstable chemistry and single use chemistry as the processing solutions need to be replaced frequently. Described herein is an improvement to the surface (24) of a drum (20) in photographic processing apparatus incorporating a drum arrangement to form a low volume processing tank. The improvement comprises forming a spiral (22) either on or in the surface (24) of the drum (20). This has the advantage of improving the process activity of the apparatus and prevents the material being processed from adhering to the drum surface.
摘要翻译： 已知在照相处理设备中使用旋转鼓。 然而，在许多实施例中，为了装置的有效操作，需要相对大量的处理溶液。 这使得大多数滚筒布置不适合用于不稳定的化学物质和单次使用化学物质，因为处理溶液需要经常更换。 这里描述的是对照相处理设备中的滚筒（20）的表面（24）的改进，该照相处理设备包括鼓装置以形成小容量处理槽。 改进包括在滚筒（20）的表面（24）上或内形成螺旋（22）。 这具有改善装置的处理活性并防止被处理的材料粘附到鼓表面的优点。

摘要： It is known to use rotating drums in photographic processing apparatus. However, in many embodiments, relatively large volumes of processing solution are required for effective operation of the apparatus. This makes most drum arrangements unsuitable for use with unstable chemistry and single use chemistry as the processing solutions need to be replaced frequently. Described herein is photographic processing apparatus which incorporates a drum arrangement to form a low volume processing tank. The arrangement comprises a processing tank (10) in which a central rotatable drum (20) is mounted. A clearance of less than 5 mm is provided between the tank (10) and the drum (20) which defines a low volume for the processing solution (30).

摘要： The invention provides a bleach fix agent comprising a dilute solution of an alkaline metal or ammonium thiosulphite or a mixture thereof and iron (III) EDTA together with a soluble sulphite. The invention is characterised in that the soluble sulphite is present in an excess of the amount required for stabilization whereby the sulphite can be sacrificially destroyed by oxidizing agents in use thereby to neutralize the oxidizing effects upon the thiosulphate. The invention is particularly suitable for ''RX'' processes and results in the possibility or eliminating the stop-bath without allowing staining of the photographic material to occur.
