Title: Improvements in or relating to the manufacture of cellulose
IPC: D21C3/00
Filed: 1942-03-11
Abstract: 555,985. Cellulose. DREYFUS, H. March 11, 1942, No. 3194. [Class 2 (ii)] In the production of cellulose from cellulosecontaining materials, the latter are subjected to the action of an oxidizing agent which acts as a source of free oxygen, or to the action of oxygen itself, in the presence of an organic acid which contains in solution a metal salt which is an oxidation catalyst. The process is applicable to the treatment of wood, straw, or grasses, e.g. ash, oak, elm, poplar, birch, beech, larch, pine, spruce, or fir. The wood or other material is preferably treated in finely divided state, e.g. in the form of sawdust or small chips. The cellulosic material may first be treated with dilute alkali, e.g. by boiling it with a 1 per cent. solution of caustic soda for about one hour. The oxidizing agent may be hydrogen peroxide, sodium peroxide, barium peroxide, oxygen, or air. The organic acid may be a lower fatty acid e.g. acetic, propionic, or butyric acid, and it may be used as a 25-75 per cent. solution in water. The treatment may be carried out at 40-70‹C. The oxidation catalyst may be a salt of cobalt, nickel, iron, chromium, aluminium, or manganese. The treatment oxidizes the lignin of the wood or other material and renders it soluble in dilute alkali. After the oxidation treatment, the material may therefore be boiled with dilute alkali. It may then be treated at ordinary temperature with caustic soda of 9-15 per cent. strength to remove hemicelluloses. The product is of high α-cellulose content and may be used for paper making or for making viscose, cellulose nitrate or acetate, or other cellulose derivative. The Provisional Specification describes also the treatment of the cellulose-containing material with an oxidizing agent such as hydrogen peroxide in the presence of ammonia.
Patent GB-538959-A (GB)
Title: Improvements in the production of cellulose esters
IPC: C08B3/22
Filed: 1940-02-21
Abstract: 538,959. Cellulose esters. BRITISH CELANESE, Ltd. Feb. 21, 1940, Nos. 3274 and 3275. Convention dates, Feb. 28, 1939, and March 24, 1939. [Class 2 (ii)] The stability to light and heat of a ripened cellulose ester of an organic carboxylic acid is improved by forming a solution of the ester, after its isolation from the acidylation mixture, in a solvent containing a small concentration of sulphuric or phosphoric acid and reprecipitating the ester after the improvement in stability has been effected. The concentration of the acid is such that no substantial hydrolysis or change of solution viscosity of the cellulose ester takes place before reprecipitation. Prior to the precipitation from the acidylating mixture, the cellulose ester may be treated with a basic salt, e.g. basic aluminium acetate, sodium aluminate, or sodium acetate or a mixture of one of these salts with hydrochloric acid, aluminium chloride or zinc chloride. The solvent should contain but little if any water in order to avoid hydrolysis of the cellulose ester. Lower aliphatic acids such as acetic, propionic, or butyric acid, may be used as solvents. The process is applicable to the stabilization of secondary acetone-soluble cellulose acetate. The stabilization may be effected at 20-25‹ C. for several hours. Cellulose acetate precipitated from an esterification solution to which a basic salt has been added may be stabilized by dissolving it in acetic acid containing from 0.05-0.2 per cent of phosphoric acid (85 per cent), or containing 0.025-0.25 per cent of sulphuric acid (98 per cent). The products obtained have substantially the same acetyl value and acetone viscosity as before treatment but their stability to light and heat is greater. In the production of the cellulose esters there may be used as cellulosic material, cotton, cotton linters, wood pulp, or regenerated cellulose. The esterifying agent may be formic acid, acetic anhydride, propionic anhydride, butyric anhydride, or a mixture of anhydrides. The esterification catalyst may be sulphuric acid, sodium bisulphate, methyl sulphate, or a mixture of these with each other or with other catalysts such as zinc chloride. The cellulose esters obtained by the process may be used in the production of artificial filaments, staple fibre, bristles, straw, foils, films, plastics, and moulding compositions. Specification 447,530 is referred to.

Filed: 1926-02-09
Abstract: 247,235. Aktiebolaget Svenska Kullagerfabrieken. Feb. 9, 1925, [Convention date]. Crank linkages. - In linkwork for converting rotary into oscillatory motion of the type in which the oscillatory member is driven by a pair of opposed rotating cranks acting through con. necting straps or the like, means are provided to compensate for the effects of the variation of obliquity of the straps, the arrangement being applicable to sphere and race grinding machines in which the blank or the grinding wheel has a motion about its own axis and an oscillatory motion about another axis. Cranks 3, 4 on a pair of worm driven shafts 1, 2 are connected by steel bands, leather straps, wires &c. 7, 8 to a drum or like oscillatory member 5 pivoted about an axis 6. In the arrangement shown the cranks rotate in the same direction. They may, how. ever, rotate in opposite directions if one of the cranks is initially turned 108‹ from the position shown. To compensate for the varying obliquity nf the straps &c., the rotary driving members may be carried by a spring or weight controlled pivoted or sliding frame as shown in Fig. 3 or the oscillatory member may be suitably shaped or arranged as by pivoting the drum 5 eccentrically so that its centre of curvature lies between its pivot and the rotary driving members or the two arrangements may be combined. Specification 15056/09, [Class 60, Grinding or abrading &c.], is referred to. The inoperative parts of the drum may be cut away. The Specification as open to inspection under Sect. 91 (3) (a) describes also arrangements in which the slight changes in length due to the obliquity are provided for by the elasticity of the straps, in which connecting rods, racks or the like may be substituted for the straps, and in which an angle lever, yoke or the like may be substituted for the drum.

Abstract: 924,798. Clutch combinations. F. A. E. PORSCHE. Feb. 3, 1961 [Feb. 4, 1960], No. 4179/61. Class 80 (2). A split-ring synchronizer 13 for clutch teeth 8, 10 has a member 16 freely mounted on the hub 11 of the carrier of the teeth 8 and having a lug 15 extending between the ends of the ring 13. On shifting the striker sleeve 5 to engage the clutch, the teeth 10 first frictionally engage the coned outer surface of the ring 13 which is thereby entrained, and the leading end of the ring engages the lug 15, shifting the member 16 which acts through a blocking band 25 on a blocking body 18 which has a projection 19 riding up a cam surface 21 formed on the hub 11 so that the body 18 is forced outwardly against the inner periphery of the ring 13. The blocking band 25 is also pressed against the ring 13. The inherent stress in the synchronizing ring is thus increased and further axial movement of the striker sleeve is prevented until synchronism is attained, whereupon the force exerted by the ring 13 on the lug 15 ceases, freeing the band 25 from stress and releasing the blocking body 18. In a modification (Fig. 4, not shown) the blocking bands 25 are replaced by segments which transmit motion to the blocking body, and anti-friction rollers are interposed between the internal periphery of the ring 13 and the members 16, the segments and the blocking body, and a roller is interposed between the projection 19 of the blocking body and the cam surface 21. In each case the rollers are freely mounted in grooves in the member with which they are associated.
