Photographic method of treating a photographic sheet with a liquid
Реферат: 1,026,170. Photographic process. INTERNATIONAL POLAROID CORPORATION. Jan. 29, 1963 [Feb. 15,1962], No. 3642/63. Heading G2C. In processes wherein two superposed photographic sheets are treated with a processing liquid via a nozzle having a discharge mouth bounded by lips at least equal to the width of the sheets and in liquid-tight contact therewith the liquid is introduced at such a pressure that the sheets are caused to advance along convergent paths past the lips and into superposition in the direction of flow of the liquid. The advancement of the sheets may be assisted by application of a force insufficient by itself to cause such advancement e.g. torque applied to a roll supporting and guiding one of the sheets. The process may be performed using the apparatus of Specification 1,026,169 which involves the use of an elastomeric container to store the liquid under pressure. The process is particularly suitable for application in the production of positives within a camera by the diffusion transfer process.
