    • A method and apparatus for processing a photosensitive material. The apparatus includes at least one processing section and a replenishment system for delivering replenishment solution contained within a container to the processing section. The replenishment system including a single device for withdrawing replenishment solution from the container and for monitoring the level of the replenishment solution contained in the container. The container is made of a material that is electrically non-conductive. A pair of spaced electrically conductive members are provided within the container. One of the members has a passageway for allowing flow processing solution therethrough and one has a terminal end which extends below the other member within the container. An AC current is applied to the pair of spaced members and the AC current is monitored with a level sensing circuit. When the replenishment solution falls below the end of the shorter member, a low level indicating signal is produced by the level sensing circuit.
    • 一种用于处理感光材料的方法和装置。 该装置包括至少一个处理部分和补充系统,用于将包含在容器内的补充溶液输送到处理部分。 该补充系统包括用于从容器中取出补充溶液并用于监测容纳在容器中的补充溶液的水平的单个装置。 容器由不导电的材料制成。 一对隔开的导电构件设置在容器内。 其中一个构件具有用于允许流动处理溶液通过的通道,并且一个具有在容器内另一个构件下方延伸的终端。 交流电流被施加到一对间隔的构件上,并且用电平检测电路来监视交流电流。 当补充液低于较短构件的末端时,液面检测电路产生低电平指示信号。

    • 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.
    • 本发明涉及一种涂覆设备,其具有用于将保护涂层施加到感光材料的至少一个表面上的可移除涂层模块。 涂布装置可以是独立的单元,并且可以添加到现有的或新的照相处理器中。 涂层产品可以是具有预定粘度的溶液,其在干燥之前施加到感光材料的至少一个表面上,以允许溶液以特定层厚度均匀地施加到至少一个表面上。 干燥后的粘稠溶液用作保护涂层,可保护经处理的感光材料免受划伤和潮湿。 可拆卸的涂层模块在粘性溶液消耗后便于维护和清洁。 该装置包括控制所施加的粘性溶液的厚度,均匀性和沉积量的控制机构,以确保提供对感光材料的整个表面提供保护的均匀涂层。
