Title: Improvements in the manufacture of cellulose derivatives
IPC: C08B3/28
Filed: 1934-10-03
Abstract: An organic ester of cellulose is precipitated from solution by adding a precipitant to the solution of the ester, which solution already contains bubbles of gas distributed throughout its mass. Primary or secondary esterification solutions, or solutions of previously precipitated cellulose esters may be employed, and the bubbles of gas may be introduced by injecting air, carbon dioxide or other inert gas into the solution, or by adding a carbonate or bicarbonate which will generate a gas by interaction with an acid already present in the solution.  In an example, a cellulose acetate esterification solution is ripened and into the solution is stirred a solution or slurry of sodium bicarbonate.  Water is added firstly in quantity just not sufficient to precipitate the p  cellulose acetate, and then in large excess with vigorous stirring.  The Specification as open to inspection under Sect. 91 refers also to a process for precipitating cellulose organic esters from solution by introducing a precipitant into the cellulose ester solution.  This subject-matter does not appear in the Specification as accepted.

Title: Recovery of vitamin-active materials
IPC: A61K31/00
Filed: 1953-10-15
Abstract: Vitamin B12-active materials, adsorbed on a cation-exchange resin characterized as deriving its cation-exchange capacity essentially from carboxylic groups, and being substantially completely in its hydrogen form, are eluted therefrom by means of an aqueous solution of an inorganic base which is substantially free of any organic base or any polar organic solvent, which solution preferably has a pH above about 10 and contains sufficient inorganic base to convert the resin substantially completely to the salt form.  The adsorbate is preferably prepared by contacting an aqueous solution containing Vitamin B12-active material (especially a fermentation broth such as that derived from the fermentation of a nutrient medium with a Vitamin B12-producing strain of Streptomyces griseus, Bacillus megatherium or Alkaligenes faecalis), and having a pH in the range of approximately 2-3, with the resin substantially completely in its hydrogen form.  Suitable resins are condensation products of resorcylic acid and formaldehyde, and especially copolymers of divinylbenzene and acrylic or methacrylic acid, preferably having a divinylbenzene content of 2.5-5 per cent by weight.  Examples describe the use, in the preferred embodiments of the invention, of 3 per cent aqueous solutions of: (1)-(3) sodium hydroxide, (4) potassium hydroxide, and (5) ammonium hydroxide, which solutions may contain a small amount of sodium cyanide to convert Vitamin B12 analogues to Vitamin B12.  Reference is also made to aqueous trisodium phosphate as an eluant, and to fermentation broths from Alternaria alevaeca, Pseudomonas sp., Mycobacterium smegmatis or S. fradiae, aqueous concentrates obtained in the working up of solutions of Vitamin B12-active substances, aqueous extracts and digestion products of microorganism cells, and sewage sludges as sources of Vitamin B12-active substances.

Oct. 18, 1933, No. 28874. Drawings to Specification. [Class 98 (ii)] A metallic sheet is coated with a silver salt emulsion of sufficient sensitivity for contact printing or for direct exposure in a camera ; and after exposure and development of the silver image a negative or a positive colloid relief is produced, under the selective control of the silver image, to serve as a resist for the metal by which to obtain a printing plate. The metallic sheet may be a copper base sheet plated with nickel or chromium or other metal inert to the emulsion layer, i.e. a metal which does not contaminate the emulsion and protects it from contamination by the copper base. The surface of the nickel &c. layer is preferably grained. Alloys may be used as well as pure metals or two or more layers of different metals, for example, a nickel layer coated with a thin layer of chromium. The developed image is converted into a negative colloid relief by a bichromate in solution (or other tanning agent) or into a positive by an oxidizing agent such as hydrogen peroxide or persulphate. The plate may then be etched through the inert metallic layer into the base plate in those parts unprotected by the emulsion resist.
