Title: Improvements in driving arrangements for textile speedframes
Inventor: BENYON JOHN
IPC: D01H1/36
Filed: 1965-01-26
Abstract: 1,117,671. Speed frames; flyers; roller drives. T.M.M. (RESEARCH) Ltd. 25 Jan., 1966 [26 Jan., 1965 (2)], Nos. 3393/65 and 3394/65. Heading D1D. A speed frame comprises a flyer carrying a presser which is traversed relatively to the flyer and means to adjust the delivery speed of the front rollers to allow for the change in the length of roving between the front rollers and the presser as the latter is traversed. A motor 11 Fig. 1, drives a shaft 13 which is the constant speed input of a conventional differential 14 and which is geared to the shaft 16 of an upper cone 17 connected by a shiftable belt 20 to a lower cone 19. The cone 19 is also conected via reversing-gears 25 to a pinion 29 which acts on a rack 28 to traverse the presser. The flyer is of the closed type comprising two vertical legs joined at the top and bottom. The presser comprises an arcuate counterweighted arm with a foot and a hollow cylindrical body portion 39, Fig. 4, which can pivot around and slide on one of the flyer legs. The flyer is supported by and moves around a ring 46 which rises and falls to provide the traverse. The portion 39 has legs 44, 45 embracing the ring which is attached by a bracket to the rack 28. To change the speed of the feed-rollers, the roller shaft 48 is the output of a differential 55 of which the input shaft is geared to the shaft 16 of the top cone at 56, and the housing is connected to pinion 29. Thus the rollers are driven at the speed of the upper cone increased or reduced by the speed of pinion 29 according to the direction in which the pinion rotates. The stroke of the traverse is gradually reduced to build the package; for the duration of each up stroke the speed of the feed rollers is reduced to prevent the roving sagging; during each downstroke the speed is increased to prevent the roving stretching. The portion 39 of the presser has a slot through which the roving passes from the flyer arm to the presser arm; the upper edge 54 of the slot in contact with which the roving passes is downwardly inclined whereby false twist is imparted to the roving to strengthen the portion moving down the flyer arm. The flyer is driven by a shaft which passes through the hollow driving-shaft of the bobbin. For ease of doffing, the bobbin is detachably coupled to its driving-shaft and centred on the flyer by a shaft (37 Fig. 2, not shown) through which the roving passes to the flyer.

Title: Process of preparing aliphatic carboxylic acid anhydrides
IPC: B01J31/04
Filed: 1950-02-10
Abstract: Aliphatic carboxylic acid anhydrides are produced by oxidation of the corresponding aldehydes by gases containing free oxygen in the presence of a metal salt of an aliphatic acid having 2-20 carbon atoms as a catalyst, the catalyst being formed in situ from a salt derived from an aliphatic acid having 1-4 carbon atoms and a hitherto used metal catalyst.  Suitable acids having 12-20 carbon atoms are, for example, stearic acid, oleic acid, naphthenic acid and acid mixtures formed by the oxidation of paraffin; and these may be added separately or in admixture with each other to the reaction mixture containing the usual catalyst salts.  The aliphatic aldehydes corresponding to the aliphatic acids having 12 to 20 carbon atoms can also be added to the reaction mixture containing the usual catalyst salts, where they are oxidized to the corresponding acids. Preferably at least 1 per cent of the catalyst salts of the acids having 12 to 20 carbon atoms are used and the reaction may be carried out continuously. A solvent may be added to the reaction mixture, especially such solvents as dissolve the anhydride formed and not the water, e.g. ethyl acetate and ketone compounds such as cyclohexanone and diethyl ketone.  In the example acetaldehyde is oxidized by oxygen and cobalt acetate; copper acetate and oleic acid are added to form the catalyst.  Specifications 443,151 and 446,259 are referred to.

Filed: 1959-02-09
Abstract: Films of regenerated cellulose are impregnated with the reaction product of a 1,2-alkylene imine (including a 1.2-polyalkylene imine) and an alkylating agent or an acylating agent, the mol. ratio of the imine to the agent being between 5 : 1 and 100 : 1 and preferably between about 8 : 1 and 40 : 1.  The alkylating agents may contain at least 4, for example up to 22, carbon atoms, those with 8 to 18 carbon atoms being preferred. e.g. 2-ethylhexyl-, decyl-, dodecyl- or octadecyl-chloride. Carboxylic acid halides are preferred, as acylating agents, and these may contain 4 to 22, preferably 8 to 18, carbon atoms in the molecule, e.g. lauroyl-, myristoyl-, palmitoyl- or stearoyl-chloride.  The reaction products may be applied as free bases in aqueous solution or as salts formed by reacting the bases with an inorganic acid or an organic acid, e.g. hydrochloric acid, sulphuric acid, formic or acetic acid.  In an example, regenerated cellulose film produced from viscose is passed through an aqueous plasticiser bath containing in grams per litre 20 of glycerol, 30 of triglycol, 30 of urea and one of a reaction product of polyethylene imine and octadecyl chloride or bromide in the mol ratio of 20 : 1, and then dried and collected on a roll in the usual manner. Regenerated cellulose films treated in accordance with the invention may be coated with a moistureproof coating (see Group VIII).  The impregnation prevents adhesion of superimposed layers of the film to one another during storage and improves the bonding of hydrophobic coatings to the film. Specification 681,494 and German Specification 662,451, are referred to.ALSO:A 1,2-alkylene imine (including a 1,2-poly-alkylene imine) is reacted with an alkylating agent or an acylating agent in a mol. ratio between 5:1 and 100:1, e.g. ethylene imine is reacted with octadecyl chloride or bromide, octyl or butyl chloride, oleic acid chloride or stearic acid chloride in a mol. ratio between 5:1 and 100:1.
