Title: Improvements in or relating to the production and use of solutions of acrylic polymers
Inventor: LINCOLN JAMES
IPC: C08J3/09
Filed: 1950-01-05
Abstract: A solvent for fibre-forming acrylonitrile polymers or copolymers comprises a nitro-alkanol having 2 or 3 carbon atoms, e.g. 2-nitro-ethanol, nitro-propanols and nitro-isopropanol. Specified copolymers are those containing 85 per cent or more of acrylonitrile and the remainder vinyl chloride, or 60 per cent or more of acrylonitrile and the remainder methacrylonitrile.  The nitro-alkanol may be used alone or diluted with a hydroxyl-containing non-solvent for the polymer, e.g. water, methanol, ethanol, propanol or isopropanol, or with another solvent, e.g. lactones such as propiolactone, butyrolactone or valerolactones, ethylene carbonate, succinic, glutaric and maleic anhydrides, and dimethyl formamide. Solution is effected at temperatures above 80 DEG  C. and the concentration of polymer is preferably not more than 25 per cent. The solutions may be extruded or cast into fibres and films, at temperatures above 80 DEG  C., preferably by wet spinning or wet casting.  Suitable coagulants are water, alcohols, glycols, glycerol and lower alkyl ethers, which may contain about 5-25 per cent by volume of the nitro-alkanol solvent.  The coagulating bath is also preferably at a temperature above 80 DEG  C.  The fibres, which may be stretched during coagulation, should be stretched after coagulation, in hot air, steam or water or in contact with a hot metal surface to a total of 5-15 times the original length.  Sticking of the fibres in yarns may be prevented by passing the yarn through an aqueous oil emulsion before or while stretching it, as described in Specification 636,476.  The oil may be vegetable, e.g. olive oil, and the emulsion may be stabilized by, for example, a higher alkyl pyridinium chloride.  The solutions may also be extruded into an inert liquid or atmosphere hot enough to evaporate the nitro-alkanol and convert it to nitroethylene.  Or the solution may be cast on to a heated wheel or band and evaporation of the nitro-alkanol assisted by a rapid hot air stream.

Abstract: 552,490. Printing-machines. ATKINS, C. F. V., and MARSHALL, F. G. Jan. 8, 1942, No. 333. [Class 100 (ii)] In a machine for printing on cans, shells, &c. the cans are passed down a chute 3 to an intermittently rotated star wheel 10 which is rotated in timed relation with ink-applying rollers 31 yieldingly mounted in brackets 28 carried by chains 27, Fig. 3, passing over sprockets on shafts 36, 36a driven by belt gearing from a shaft 13a driven by a motor 47, which also drives belts 11 passing around adjustably mounted pulleys. The belts 11 engage the edges of the cans and roll them over rails 2 which guide the cans across the adjustably mounted printing-surface 23 which is inked by the rollers 31. The belts 11 pass over pulleys 12 which can be adjusted laterally for dealing with cans of different lengths, and the pulley supports can be adadjusted vertically by screw mechanism for cans of different diameters. The chains 27 run upon chain guides 39 while passing over the die, and the rollers 31 pass over an inking-pad 40 mounted in an adjustable tray 48, and the pad may be supplied with ink from a reservoir by means of a wick. The shoots 3, 4 are supported at an adjustable angle by means of struts 5 with adjustable connections 6 with the supporting frame 1, and the belt drive between the shafts 13a, 36a passes over an adjustable pulley 62a to allow for adjustments of the belts 11. Star wheels 10 with pockets of different sizes may be used, or the pockets of one wheel may be adjustable.

Title: Improvements in and relating to packaging machines, particularly for packaging cigarettes
IPC: B65B19/02
Filed: 1941-02-20
Abstract: 550,042. Packeting; making paper and like bags. AMERICAN MACHINE & FOUNDRY CO. Feb. 20, 1941, No. 349. 'Convention date, Feb. 20, 1940. [Classes 94 (i) and 94 (ii)] Relates to a packeting machine of the kind described in Specification 328,310, [Class 94 (i)], in which packets are formed by folding wrappers about travelling mandrels, and cigarettes are inserted in the packets while still in the mandrels. According to the invention, the wrapper-folding means includes a clamp for each mandrel for pressing a wrapper against one face of the mandrel, and a channel-shaped folder movable with the clamp to fold the clamped wrapper about two sides of the mandrel. The invention also includes means for feeding successive wrappers to the mandrels, and for pressing them againt the sides and corners of the mandrel during the folding-operation. The machine comprises a turret which is rotated intermittently about a horizontal axis and carries the mandrels step-by-step from one operating station to another. At station A, Fig. 3, an inner wrapper F of metal foil is folded around a hollow mandrel M, and at station B an outer wrapper or label L is folded about the wrapper F, the folding of this wrapper being completed by suitable folders at stations between A and B. At station A, the wrapper F which has been cut off from a strip of foil is applied to the mandrel by a clamp 139 that is pressed resiliently against the mandrel by an arm 138. The arm also carries a U-shaped folder 142 which folds the wrapper about the narrow sides of the mandrel, as shown in Fig. 5. The folding is completed by pivoted folders 121a, 130a., and by a plate 120a, which lays the longer flap of the wrapper smoothly over the shorter flap. Each of the folders, 121a, 130a, is provided with a rubber cushion 127a to press the wrapper firmly against the sides and corners of the mandrel. The overlapping flaps of the wrapper are then held against the mandrel by a known seam clamp. At the station preceding B, the arm 138 is moved away from the mandrel and the outer wrapper or label L is fed into position beneath the mandrel. As the mandrel moves toward B, the presser plate 139 and the folder 142 are again operated to fold the label L about the wrapper F, and the folding is completed by folders similar to 120a, 121α, and 130a, the overlapping flaps of the wrapper being sealed together by a strip of adhesive which has been applied by suitable mechanism. The wrappers or labels L are fed from a magazine towards station B by pushers 23, Fig. 2, on conveyer chains 22 which pass along a plate 24, adhesive being applied during this movement. From the pushers 23, each wrapper is moved into contact with adjustable stops 32 by fingers 11 which move in an approximately rectangular path as shown by the arrows. Specification 377,022 is referred to. The Specification, as open to inspection under Sect. 91, comprises also the subject-matter of divided applications 550,065 and 550,066. This subject-matter does not appear in the Specification as accepted.

[Class 83 (iv)] [Also in Group XXIII] A support for a number of work-supporting vices for use during soldering or welding &c. operations, consists of a stand c bearing a bedplate a provided with two or more guideways b in which vices of known type are free to slide and pivot in order to take up any position. The guideways b may be arranged in any desired angular relationship. The back portion of the fixed jaw e of each vice is of angular formation so that adjacent vices may be brought close together. A fitting for facilitating vertical angular adjustment of the vices consists of an arm m, Fig. 8, to which is pivoted an adjustable arm n provided with a similar guideway in which a vice o may be clamped. The vices may be provided with a calibrated disc, to enable accurate orientation of the vices to be made. The bed-plate a may be covered with heat-resistant material between the guideways.

Abstract: In a process of producing lubricating and similar viscous oils by the polymerization, in the liquid phase and in the presence of aluminium chloride, zinc chloride, ferric chloride or similar metal halogenide, of olefines or olefine-containing mixtures obtained by cracking hydrocarbon material, the polymerization is effected in the presence of between 1 and 30 per cent of water, preferably between 2 and 10 per cent, calculated in the quantity of metal halogenide.  The water may be added either before or during the polymerization, and in the latter case may be added in one or more portions.  In an example, benzine containing olefines obtained by cracking paraffin wax in the vapour phase is polymerized in the presence of aluminium chloride and water.  The product is washed with water and concentrated.  According to the Specification as open to inspection under Sect. 91, the process is applied to liquid olefines and olefine-containing mixtures generally.
