Title: Process for the manufacture of intaglio printing rollers or cylinders
IPC: B41N1/20
Filed: 1932-04-25
Abstract: 388,249. Electro-deposition of copper. LANGBEIN - PFANHAUSER - W E R K E AKT.-GES., 76, Torgauer Strasse, Leipsic,' Germany. April 25, 1932, No. 11799. Convention date, April 25, 1931. [Class 41.] An intaglio-printing roller having a copper layer which is mechanically strippable is formed by depositing on the surface of the cylinder, which is formed of or coated with copper, a layer of copper of which the portion first applied is of such different texture from that ordinarily produced by electro - deposition that its adherence to the cylinder is comparatively low, while the remainder of the layer is thereafter applied by known methods of electro-deposition. In the preferred form, a polished copper cylinder is initially plated by rotating it for a short time under a current density of À3 to À5 amps. per square decimetre in a bath containing 75-100 grs. of pure crystallized potassium copper cyanide and 20 grs. of caustic soda per litre, such that the bath contains little or no cyanide not in the form of complex metal salts, and this initial layer is then increased to a thickness of .1 or .15 mm., suitable for one etching by plating in a normal copper-plating bath, containing for example 220 grs. copper sulphate, 15 grs. sulphuric acid per litre and with a current density from 3 to 10 amps. per square decimetre. The different textures of the two layers may be obtained in various ways, as by selecting a different current density, temperature and/or composition of the electrolyte.

Title: Improvements in anthraquinone derivatives
IPC: C07C45/72
Filed: 1931-04-22
Abstract: Dyes and intermediates of the benzanthrone series.--A 2-phenylanthraquinone containing a halogen or hydroxy group in the phenyl residue, is reacted with sulphuric acid, glycerine, and a metallic reducing agent, preferably in powdered form.  A mixture of isomeric benzanthrones results and those products having a free 2-position in the anthraquinone nucleus may be fused with alcoholic alkali to give dyestuffs.  In examples, (1) 2 - p - chlorphenylanthra - quinone is treated with sulphuric acid, glycerine, and copper powder at 118-120 DEG  C.; after removing alkaline water-soluble impurities extraction with cold and hot alcohol and then benzene separates three isomeric chlorphenylbenzanthrones.  (2) Similar treatment of 2-o-chlorphenylanthraquinone yields a mixture of isomeric chlorphenylbenzanthrones and similarly with 2-m-chlorphenylanthraquinone.  The conversion of 2-m-hydroxyphenylanthraquinone and of 2-o-bromphenylanthraquinone to isomeric mixtures of hydroxyphenyl- and bromphenylbenzanthrones respectively is also mentioned.  Instead of copper other metal reducing agents, such as iron and aluminium may be used.  (3) A b -p-chlorphenylbenzanthrone produced according to (1) is fused with alcoholic potash to give a green-blue to steel-blue vat dye; a number of structural formul  are assigned to the products of (1) and to the dyes derived therefrom; the isomeric mixtures obtained in the glycerine condensation may also be alkalifused.  The intermediates have the benz-2-position free and permit oxidation to phenyloxydibenzanthrones; those intermediates containing halogen as well as the dibenzanthrone derivatives derived therefrom are capable of condensation with primary amino compounds.  The 2-phenylanthraquinones are prepared by condensing phthalic anhydride with the appropriate diphenyl derivatives in presence of aluminium chloride and ring-closing the product in presence of sulphuric acid. Specification 300,331, [Class 2 (iii), Dyes &c.], is referred to. The Specification as open to inspection under Sect. 91 also relates to reaction of 2-phenylanthraquinone as described above, and the use of an acid generally, instead of sulphuric acid, is specified.  This subject-matter does not appear in the Specification as accepted.

Title: Process for the production of improved hydrocarbon oils
IPC: C10G21/00
Filed: 1956-04-23
Abstract: Lubricating oil is extracted with a solvent selective for aromatic hydrocarbons, and a heavy catalytically cracked oil is extracted with the extract phase; an improved aromatic oil is obtained by removing solvent from the resulting extract phase. Selective solvents referred to are furfural, phenol, nitrobenzene, sulphur dioxide, cresylic acids and sulpholane; the extraction of lubricating oil may be continuous or batchwise.  The catalytically cracked oil may have an initial B.P. of at least 260 DEG  C.  The raffinate from the extraction of the cracked oil contains paraffins from the lubricating oil and the cracked oil and may be separated into higher and lower M.W. fractions; the higher M.W. fraction may be blended with the raffinate from the first extraction.  If the blend of raffinate is to be used as a lubricating oil, it may be dewaxed, e.g. by solvent dewaxing.

Title: Improvements in and relating to the manufacture and production of powdered soap
IPC: C11D13/20
Filed: 1929-04-22
Abstract: 332,590. Welter, A. April 22, 1929. Soaps, powdered.-In the production of soap powder in which liquid grain soap is heated by injection of compressed steam, and then atomized under the pressure prevailing in the vessel, solid electrolytes having a salting-out action are added before heating, and after separation into layers, and if desired removal of the lower aqueous layer, the upper layer of liquid grain soap is atomized. Salts such as common salt or caustic alkali are used. The heating by injection of steam may be replaced by direct fire-heating or by a steam jacket when a concentrated solution of the salts is used. By this treatment dilution of the liquid grain soap, and the formation of crusts on the sides of the vessel during heating, is prevented. The upper empty part of the vessel may be filled with compressed steam or air during the treatment. In an example, liquid grain soap is introduced into an autoclave with common salt and steam is injected until a pressure of 4 to 10 atmospheres is reached. After standing, the layer of liquid grain soap floating on the lower layer of concentrated salt liquor is forced by the pressure in the vessel through a pipe lowered therein, and passes to an atomizing chamber, to produce a dry soap powder.

Title: Manufacture of alkali-cellulose
IPC: C08B1/08
Filed: 1944-06-30
Abstract: Alkali-cellulose of low water content and very suitable for the manufacture of cellulose ethers is made by immersing cellulose, e.g. cellulose pulp in any form, especially in sheet form, in a concentrated aqueous solution of alkali for 1/2 to 20 seconds at a temperature of 60 DEG  to 90 DEG  C., and expressing the excess alkali solution immediately after the immersion, so that wetting of the cellulose proceeds more rapidly than the swelling. The alkali may be caustic potash or caustic soda and may be employed in solution in a concentration of 20 per cent up to but not above the saturation concentration at room temperature.  In the examples: (1) cellulose pulp in the form of a roll is treated in a foulard with a 40 per cent caustic soda solution at 60-70 DEG  C. for 3 seconds, and squeezed. The alkali-cellulose may be used for the manufacture of water-soluble cellulose ethers; (2) cellulose pulp from a roll is passed through a 50 per cent caustic soda solution at 80 DEG  C., the time of treatment being 5-6 seconds, and squeezed.  The alkali cellulose so obtained is then mixed at 90 DEG  C., with solid caustic soda and cooled to form a product suitable for the manufacture of cellulose ethers soluble in organic solvents.
