Abstract

316,784. Maskell, L. H. Aug. 16, 1928. Copying-telegraphs.-A print, produced by the electrolytic liberation of iodine on paper from a potassium iodide-starch solution by the action of a recording stylus, is fixed by washing with a weak acid solution, such as boric acid. or a solution of a substances which does not react with the image and gives a suitable hydrogen ion concentration, such as potassium bisulphate.
