Abstract

1,132,067. Liquid level control. KODAK Ltd. Nov.25, 1965 [Nov.27, 1964] No.48441/64. Heading GlH. [Also in Division G2] A flexible container 1 holding photographic processing liquid is connected via tubes 2 and 4 to processing tray 5, and also via a tube 3 to a closed reservoir 6 above tray 5. The reservoir supplies liquid directly to the tray through a tube 7, and an air inlet tube 8 is adjustable in height above the bottom of the tray. Container 1 is compressed by forcing a plate 9 upwards, which squeezes the container against a plate 10. At the, same time, the flexible inlet tube 4 is constricted between projections 12 and 13. Liquid enters both tray 5 and reservoir 6, and the liquid level in the former is then maintained constant by the "chickenfeed" principle. To return liquid to the container 1, the pressure thereon by plate 9 is released. The flexible tube 4 may be replaced by a rigid small-bore tube. The tube 2 may also be made long enough to allow container 1 to be lifted higher than reservoir 6, so that the liquid runs out of it under gravity.
