Abstract: 884,189. Making longitudinally seamed tubing; skelping by rolls. TUBE MAKING MACHINES Ltd. July 5, 1960 [July 9, 1959], No. 23662/59. Classes 83 (2) and 83 (4). A machine for making metal tubing of the type comprising a series of pairs of forming rolls 10 for forming a strip of metal into tubing having a longitudinal gap between its opposed edges and continuously advancing the tubing to a welding head 40 and a series of pairs of sizing rolls 15 situated beyond the welding head which serve to straighten and size the welded tubing is characterized in that all the pairs of forming and sizing rolls are driven at the same nominal speed from a common prime mover, all pairs of forming rolls being driven through friction clutches and at least one pair of rolls situated at a point beyond that corresponding to formation of the tubing being positively driven. Strip formed into a tube by the rolls 10 is fed by rolls 11 through idler rolls in the welding head where the seam is welded by argon arc or high- or low-frequency means. From the welding head 40 the tube passes through a cooling unit 14 and the sizing rolls 15 to a cut-off unit 16. The rolls 10, 11 and 15 are driven at the same nominal speed from an electric motor 18, gear-boxes 19 and shaft 20. The rolls 10 are driven from the feed rolls 11 through chain and sprocket gearing 21 and friction clutches. The forming rolls 10 are mounted on shafts 25 geared together by gears 12. A sprocket 26, loose on an extension of the lower shaft 25, rotates the shaft 25 through a clutch plate 27 splined on the shaft 25 and pressed by an adjustable spring 29. The first pair of sizing rolls 15 is positively driven and the other sizing rolls 15 driven from the first pair through chain and sprocket gearing 22 and friction clutches. All the rolls 15 could be positively driven. The rolls 10, 11 and 15 could be driven through worm gearing from a common longitudinal shaft.

Title: Improvements in or relating to cable, wire or rope drums, reels or the like
IPC: B65H75/14
Filed: 1961-07-03
Abstract: 954,244. Reels. J. HILL. Oct. 3, 1962 [July 3, 1961], No. 23874/61. Heading B8M. A drum or reel comprises a barrel on which cable, rope or wire is wound and which is rotated relatively to side or end flanges of the drum during unwinding of cable &c., the remainder of the drum then being at rest, e.g. by standing on the flanges. The barrel may be a cylinder revolving either on a cylindrical or tubular base of the drum or on a central shaft or spindle. The drum shown has a rigid barrel 10 connected as by spokes 15 to a tubular periphery 12 rotatable about a hollow shaft 13 fixed to flanges 14 comprising reinforcing gussets 16 extending between shaft 13 and a cylindrical plate 27 to which is secured a radially fluted annulus 28. A false flange, as at 17, Fig. 1, or radially extending pegs 18, Fig. 2 (of smaller diameter than flange 14) may relieve pressure exerted by cable &c. against flange 14. The barrel or projections therefrom may have side rollers making sliding contact with the inner faces of the flanges, Fig. 4 (not shown). Rotation of barrel 10 on shaft 13 may be prevented by sliding keys, as at 21, in keyways on the shaft, Fig. 3, or locking pins, Fig. 7 (not shown). In the unwinding position of the drum, the flanges are secured against rolling by scotches 24, the shanks 25 of which are displaceable within channels 26 mounted on spokes 32. In preparing for unwinding, axial displacement of one or both flanges 14 to increase the effective width of the drum is rendered possible by manual operation of a cam on shaft 13 coacting with a cam face on the flange hub, Figs. 5 and 6 (not shown). Specification 652,483 is referred to.

Filed: 1937-09-01
Abstract: 501,603. Artificial silk; dyeing. SOC. INDUSTRIELLE DE MOY, and BURET; R. Sept. 1, 1937, No. 23944. [Classes 2 (ii) and 15 (ii)] Artificial threads, fibres, ribbons, or films are made from a cellulosic solution, e.g. viscose, to which is added a syrup comprising an alkalisoluble phenol-aldehyde condensation product, and acid or basic dyestuffs are introduced into the spinning solution, or are applied to the spun threads or the like, without any subsequent polymerizing or hardening operation. To the condensation product there may be added also plastifiers, solvents, finely powdered pigments, or oxides or metal salts such as those of aluminium, chromium, cobalt and copper, capable of forming alkali-soluble compounds with the condensation products. To the spinning solution there may be added oils or pigments capable of decreasing the lustre of the fibre, or inert gases or substances capable of producing gases so as to obtain hollow fibres. The fibres may be mixed with silk or wool and dyed in a single bath without mordanting. In an example: (1) phenol is condensed with formol in the presence of caustic soda, acidified, evaporated, and the residue dissolved in caustic soda solution. This solution is added to viscose which is then spun, and the filaments obtained are dyed with a basic dye, e.g. malachite green; (2) filaments obtained as above are woven with viscose rayon and the fabric dyed with acid green J.G.; (3) filaments obtained as in (1) are dyed with acid violet 6BN ; (4) phenol and formol are condensed in the presence of an acid catalyst and the product, dissolved in caustic solution, is incorporated with viscose which is spun. The thread obtained is passed directly into a solution of rhodamine 6G ; (5) phenol and formol are condensed in the presence of caustic soda and glycerine, and the product together with acid red XB is incorporated with viscose ; (6) cresol is condensed with formol in the presence of caustic soda, and the product is incorporated in viscose. The spun threads are dyed with orange II ; (7) viscose containing the condensation product of the previous example is spun, and the thread obtained mixed with wool and dyed with an acid chromatizable dyestuff.
