We use Optical Character Recognition (OCR) during our scanning and processing workflow to make the content of each page searchable. You can view the automatically generated text below as well as copy and paste individual pieces of text to quote in your own work.
Text recognition is never 100% accurate. Many parts of the scanned page may not be reflected in the OCR text output, including: images, page layout, certain fonts or handwriting.

Claifn 4' The conversion of a photographic silver print in a colloid layer containing also silver bromide to a pigment blue print and silver bromide, by treatment in a bath containing in combination the necessary ingredients for producing the blue image and a bromide and a chloride followed by exposure and development to produce a second image in the same colloid layer. F. E. Ives, U. S. No. 1,538,816. May 19, 1925. Filed Feb. 15, 1923
Claim 1 : In photographic color print making, the production of a silver image which is converted in part to silver ferfocyanide, followed by reconverting the silver ferrocyanide to silver bromide, and then exposed to light under another negative, and developing a second silver print which is subsequently converted into a color print.

Division A — Methods of producing dye images by means of mordants. Arthur Trauhe, U. S. No. 1,093,503. Apr. 14, 1914. Filed May
15, 1907
Claim: The process of converting silver prints into pure color prints, which consists in converting the material of which the picture is composed into substances capable of being colored directly and soluble in fixing compounds, then coloring the pictures with basic dyes, and treating the colored pictures with a mixture
