Title: Improvements in dyeing wool
IPC: D06P3/20
Filed: 1924-07-19
Abstract: Hematin or other chrome mordant dyestuff is ground with 10 to 15 per cent of sodium carbonate, so that the addition of the mixture to an exhausted chrome mordant bath in sequence dyeing renders the bath alkaline.ALSO:Wool is mordanted in a boiling bath of sodium or potassium bichromate, glycerine, glucose, invert sugar, starch, dextrin, urine, tanning agents or mixtures thereof as reducing agent and acetic, formic, lactic, hydrochloric or sulphuric acid in slight excess.  A process of sequence dyeing may be carried out by mordanting as described with 1-1 3/4 per cent of bichromate, calculated on the wool and adding a chrome dyestuff, such as bematin, fustic or bark extracts, alizarines, gallocyanines, Mordant Yellow and Palatine Chrome Black, to the same bath. Preferably the bath is rendered alkaline before addition of the dyestuff and the dyeing carried out in slightly alkaline, neutral, or slightly acid bath. The alkali may be added together with the dyestuff with 10-15 per cent of sodium carbonate.  Examples show the mordanting with each of the above reducing agents, maize dextrin and myrabolam extract being used for the dextrin and tanning agent respectively, and a dye being subsequently added together with sodium acetate or acetic acid.

Abstract: 502,791. Starch. POLLAK, J. E. (International Patents Development Co.) June 22, 1937, No. 17379. Drawings to Specification. [Class 121] Mill starch obtained by steeping and comminuting maize and separating germ and slop is subjected to a series of centrifuging operations in countercurrent to a wash water introduced into a later centrifugal of the series, the starch underflow and the gluten overflow moving in opposite directions through the series, at least a part of the gluten-bearing overflow from a later centrifugal being introduced into the first centrifugal. The overflow from the first centrifugal is treated to remove the gluten and is then returned to the steeps. Waste process water from any stage is, in general, re-used in an earlier stage of the process. The starch milk, or a dilute component thereof, e.g. from the fine slop separation, may be concentrated before being fed to the centrifugals. A part of the overflow from a centrifugal may be returned to that centrifugal. Some of the starch may be removed in gravity separators from the starch milk before the latter is fed to the centrifugals. The process is illustrated by flow sheets. Specifications 277,572, [Class 121], and 419,286 are referred to.
