Abstract: A photographic processing sleeve is provided for receiving and processing a dye donating instant film sheet to produce a photographic print. The sleeve comprises a film retaining sheet that is folded over along its lateral edges to form channels which slidably receive the film sheet, and edge strips, sometimes called side rails, which space the film sheet from the image-receiving sheet. After processing, at least a major portion of the image-receiving sheet, including the finished picture, is adapted to be peeled apart from the rest of the sleeve which can then be discarded.

Abstract: An improved dry-operative ion-selective electrode for the determination of sodium ions in aqueous fluids includes a dried internal reference electrode, a dried reference layer and a sodium ion-selective membrane composed of a binder material. The reference layer contains a metal salt and a hydrophilic binder material, and is buffered to a pH of from about 4 to about 8 with a water-soluble, organic dicarboxylic acid. This electrode can be manufactured with significantly less waste and exhibits improved uniformity in performance.
