Filed: 1937-09-09
Abstract: 501,768. Artificial filaments etc.; dyeing processes. MELLOR, A., MANN, R. J., and NOON, R. W. Sept. 9, 1937, No. 24614. [Classes 2 (ii) and 15 (ii)] Regenerated cellulose filaments, yarns, ribbons, and the like obtained by completely saponifying high tenacity cellulose organic ester materials are subjected to a swelling treatment with an aqueous solution of a strong mineral alkali in order to increase the affinity of the materials for cotton dyes, including direct dyes, azo dyes, and vat dyes. The high tenacity filaments of cellulose acetate or other cellulose organic ester may be obtained by stretching during a wet spinning process, or by stretching in presence of a softening agent subsequent to wet or dry spinning. The tenacity may be up to 6 grams per denier. The saponification may be effected by means of organic bases. For the swelling treatment of the saponified materials there may be used caustic potash or soda, lithium or barium hydroxide. Treatment with the swelling agent may be effected by dipping, or padding methods, and the yarns may be in package form, in hanks, or may be travelling from one package to another. The swelling may be effected at low temperature. The treated materials may be washed before being passed to the dye bath. Swelling and dyeing may be effected in a single bath. In examples, completely saponified high tenacity cellulose acetate yarns or fabrics containing them are swollen with caustic soda, caustic potash, or lithium hydroxide solution. The materials are then dyed with diphenyl blue-green BL, or chlorazol fast black BK. In another example, the materials are dyed in a bath containing indanthrene blue RK, indanthrene olive green B, caustic soda, and sodium hydrosulphite. Salt is added to assist exhaustion of the dye. The materials are subsequently treated with bichromate solution. Specifications 417,220, and 429,103 are referred to. The Provisional Specification includes also the treatment of high tenacity regenerated cellulose materials obtained by methods other than saponification of cellulose ester materials, and includes the treatment of films.

Patent GB-359620-A (GB)
Title: Improvements in the manufacture and production of hydrogen
IPC: C01B3/26
Filed: 1930-08-20
Abstract: In the production of hydrogen by the thermal decomposition of gaseous hydrocarbons, such as methane, ethane and propane, by passage over a catalyst contained in a chamber which is preheated by the combustion therein of, for example, part of the gas to be treated, the formation of the oxides of carbon is avoided by employing as catalyst a mixture of oxides which are free from metals capable of oxidation during the preheating period, or from compounds of these metals reducible under the conditions of the reaction.  Mixtures of the oxides of aluminium, boron, zirconium, silicon, cerium, thorium, or of the alkaline-earth metals may be employed or compounds containing two or more of these oxides may be used, such as aluminium silicate.  The temperatures employed lie preferably between 1000 DEG  and 1300 DEG  C., and increased, reduced or atmospheric pressure may be used.  In examples, the catalysts consist of mixtures of aluminium hydroxide and zirconium oxide, magnesium oxide, boric acid and zirconium oxide, and aluminium hydroxide, boric acid and silica, the catalyst being made into a paste with a binding agent such as water or a dilute organic acid, formed into cubes and dried.  The gas is passed through the reaction chamber at a pressure of about 20 millimetres above atmospheric pressure, while the temperature lies between 1200 DEG and 1250 DEG  C.  Part of the carbon produced passes off with the gases produced and part remains in the catalyst or on the walls of the reaction chamber.
