Abstract: A compact, simple, fully automatic table-top plate processor for developing offset plates which are inserted horizontally in the front and ejected horizontally from the rear using paired transport rollers and brush rollers training the plate at the exit and thus provides a finished press-ready or storable plate in one cycle. Top rollers fit into essentially vertical slots and have keyed bearings to prevent rotation. The roller drive motor is of such a speed as to provide the proper dwell time prior to the plate being brushed on both sides. The processor provides automatic developing of the plate in an essentially horizontal feed-through operation permitting use on the top of an existing table surface and requiring a minimum of space. By combining the gum into the developer solution the need for several stages (develop, rinse, condition, gum, etc.) is eliminated and this one step machine provides a unique compactness of design.

Abstract: Apparatus and a process for electroylic recovery of silver from fixing baths obtained by development of photographic films wherein the fixing bath solution coming from the tank for the fixing bath to the development apparatus is fed from the development apparatus into one chamber in a recovery apparatus comprising two chambers until the said first chamber is filled whereupon the silver precipitation is started in the said chamber; an automatic redirection of the liquid flow from the development apparatus to the second chamber of the recovery apparatus is made to the said second chamber which being filled with liquid during the precipitation process in the first chamber. After concluded silver precipitation in the first chamber the liquid treated therein is automatically fed to the sewage. When the second chamber has been filled the precipitation process in the same is started. Simultaneously the liquid flow from the development apparatus is automatically fed to the first chamber which now is empty.

Abstract: A cartridge for containing and dispensing caulking compound comprises an elongated tubular member, generally cylindrical in configuration, one end of which has a fixed end wall including a dispensing opening therethrough and a spout attached to the end wall, while the other end of the tubular member is closed by a resilient, annular, floating member slidably mounted within the tubular member. The floating member is impervious and is made of a flexible material. When employed in conjunction with a standard caulking gun of the plunger type, the force of the plunger bears directly on the floating member which thereby expands in diameter and decreases in width and transmits pressure to the caulking for dispensing. When the plunger is suddenly withdrawn, the expansion of the floating member effectively absorbs the pressure forces within the cartridge thereby minimizing the amount of undesirable leakage of the caulking from the cartridge.
