Abstract

105,920. Brayer, A. de. April 25, 1916, [Convention date]. Chemicals, storing, conveying, and applying.- Chemicals for use in photographic operations are prepared in a pasty form by incorporating them in a finely divided condition in a syrupy or viscous material which is soluble in water and does not exercise any deleterious effect upon the chemicals, and a colouring material such as an aniline dye is incorporated in the paste so that the emulsion of a plate &c. may become stained with the dye &c. when treated with the chemical, the removal of the dye during washing then indicating the sufficiency of the washing. The paste may bo enclosed in collapsible tubes of tin or other material, the interior surfaces of which may be coated with a varnish to prevent reaction between them and their contents. In the Specification as open to inspection under Sect. 91 (3) (a) it is stated that the orifices of the tubes may be of such a size that known lengths of - the extruded paste may contain known quantities of the chemicals.
