Fuente: WIPO "rice" 22,291. Rice, W. G. Sept. 26. Trays, dishes, and containers with transfer arrangements for daylight developing &c.-A daylight developing-dish is fitted with a cover which allows liquid to flow into the dish in a light-trapped channel at the edges, and carries a thermometer and time-scales indicating the time for development. The cover 18, Figs. 2 and 3, has stepped portions on three sides resting on stepped edges 16, 17 the stepped edges 16, 17 of the fourth side being separated from the stepped portions of the cover forming a light-trapped zigzag path for the developer. A central boss on the cover forms a handle, and a tube 25 allowing air to escape passes through the boss and is bent round to abut against a piece of blotting-paper or absorbent material 27, which absorbs any small drops of developer that may accidently get in and clog the tube. The cover is also recessed at one side for the stem of a thermometer 30, Fig. 5. The lower part of the stem is bent round through the cover and is enclosed by a casing 32 and filling 33 such as cement. The recess 29 is covered by a glass 34 bearing a thermometer scale and a time-scale indicating the time for development corresponding to the temperature indicated and for the particular developer. The base of the dish has ledges 36 on which the lowest plate rests film-side upwards. To develop several plates, spacing-plates are used having spacing depressions or lugs formed near the edges. To keep the plates from the sides of the dish, to allow the developer to flow freely, vertical ridges or abutments 37 extend laterally inwards, the abutments 37 on the side of the thermometer being somewhat longer to allow space for the thermometer. To save space the thickened portion 15 of the wall of the dish is cut away at 41, and the tube 32 of the thermometer extends right to the bottom of the dish, where there is a shallow depression 42.
