摘要： An electrolytic cell for the recovery of silver from a photographic fixer solution is of generally cylindrical configuration. The cell has a screw-on lid that carries the disposable cathode of the cell. Inlet and outlet for the solution are at the bottom of the cell. The anode is tubular and extends upwardly from the outlet at the base of the cell towards the lid. The cathode is easily replaced, together with the lid, and flow through and the dimensions of the cell are arranged to avoid entrapment of gas therein.

摘要： Recovery of silver from a photographic fixer solution in an electrolytic cell is controlled so as to maintain a high current efficiency whilst minimizing unwanted side effects. The rate of change of plating voltage at constant current through the cell is monitored, and in response to detection of a maximum value thereof the current is reduced to a new constant level. Such control allows the cell to be operated continually at high current efficiency in response to changing chemical conditions within the cell.

摘要： A system and method are provided for the safe removal of a wet, fully-plated cathode from a silver recovery cell and its replacement by a fresh cathode. The fresh cathode is brought to the recovery cell in a transport housing, which is then docked thereto. A drip tray is unfolded from the transport housing so as to extend across and surround the top of the recovery cell. The fresh cathode is removed from the transport housing and put to one side. The used cathode is removed from the recovery cell, preferably by being attached to the lid which is unscrewed therefrom. The cathode is then transferred to the housing over the drip tray which catches any liquid falling therefrom. The used cathode is screwed into the transport housing, and the housing removed to a refiner for safe disposal, whilst the fresh electrode is screwed onto the recovery cell.

摘要： A processed sheet of photographic film is guided into a channel of scanning equipment in which it is subjected to light from an elongate fluorescent tube. Light transmitted through the film is detected by a sensing arrangement in the form of an elongate solar cell strip. The strip is scored so as to divide it into 3 small subsidiary sensors and four longer sensors. All seven sensors form the main light sensor. As the leading edge of the film, which is assumed to be of uniform light density, enters the channel and totally obscures at least one of the subsidiary sensors, that sensor measures the transmittance of the film. This value, together with the reduction in light sensed by the main sensor, is then used to determine the width of the film. The film width is combined with the separately computed film length, to provide a signal used to control the amount of replenishment chemicals to be supplied to a photoprocessor.
摘要翻译：经处理的照相胶卷片被引导到扫描设备的通道中，在该通道中经受来自细长荧光管的光。透过薄膜的光通过细长太阳能电池条的形式的感测装置来检测。该条被打分，以将其分成3个小的辅助传感器和四个更长的传感器。所有七个传感器组成主要的光传感器。由于膜的前缘被认为具有均匀的光密度，所以进入通道并完全遮蔽至少一个辅助传感器，该传感器测量膜的透射率。然后，该值与主传感器感测到的光的减少一起用于确定膜的宽度。胶片宽度与单独计算的胶片长度组合，以提供用于控制供应给光处理器的补充化学品的量的信号。

摘要： An electrolytic cell for the recovery of silver from a photographic fixer solution has a cylindrical cathode secured to and depending downwardly from a screw-on lid of the cell into the solution. The cathode is formed from a sheet of graphite foil laminated to a polyester base, and is clamped at its upper periphery around a boss of the lid. A metal connection ring is embedded around the outer periphery of the base and is contacted by the cathode. This arrangement is particularly suitable for allowing a thin, flexible disposable cathode to be conveniently removed from the cell by means of the lid, without the user being exposed to contact with the silver or with the solution.
