Title: Improvements in and relating to machines for twisting textile yarns
Inventor: MACKIE JOHN KAY PRINGLE
IPC: D01H1/10
Filed: 1964-06-25
Abstract: 1,102,974. Two-for-one twist apparatus; false twist apparatus; winding apparatus. JAMES MACKIE & SONS Ltd., 4 June, 1965 [25 June, 1964], No. 26340/64. Headings DID and D1J. To reduce the occurence of irregularities arising from the tendency of the twist to run to thin places in the yarn in 2:1 outflow twisting apparatus, a false-twist device is positioned near the take-up means to engage the yarn emerging from the balloon, and is arranged to be rotated in the same direction as the flyer and at such a speed as to concentrate substantially all the twist which would otherwise be present in the balloon in the short length of yarn between the false-twist device and the take-up means. In Fig. 2, the twisted yarn is taken up on a package on a spindle 92 mounted on a pivoted arm 94 urged against one, 34 of two driven feed rollers 32, 34 which cooperate with a jockey 35 to feed the yarn from an adjacent twist-tube 30. The latter is rotated at twice the speed of the flyer to remove the twist in the yarn in the balloon and insert equivalent twist in the length of yarn between the tube and the rollers. To keep the length of yarn between the tube and the package constant, the twist-tube is reciprocated on the arm 94 is reciprocated along the shaft 96 on which it is pivoted by an arm 100 which is pivoted at one end, 102, and connected at the other to a follower 108 which is reciprocated along a rod 116 by a traversescroll 114. The flyer, the false-twist tube, the rollers 32, 34 and the scroll are driven from a common source. The package on the 2:1 apparatus is kept stationary by a weight 56, Fig. 3, not shown, or as in Specification 989968 Hdg. D1-2; the package may provide two yarn-ends or there may be two packages. When the yarn is wound on a conical former, the jockey 35 is in contact only with roller 32 which rotates more slowly than roller 34. In the case of a multi-spindle machine, the arms 34 do not slide on shaft 96, but the latter is arranged to be reciprocated by the arm 100.

Abstract: 734,679. Cables. HACKETHAL-DRAHTUND KABEL-WERKE AKT.-GES. Nov. 14, 1951, No. 26724/51. Class 36. [Also in Group XXII] In making a cable a sheath is formed from a metal e.g. steel strip as a tube spaced from the core, the seam is welded and thereafter the sheath is transversely corrugated whereby the core is in contact with the furrows of the corrugations. Steel strip 4 is formed into a tube about core 1 in a tool 5, is resistance welded by roller electrode 11 and the sheath is corrugated helically at 8. To influence the capacity &c. of the cable a conducting layer may be arranged to form the outer core layer e.g. in the form of flat copper wires or strip or the inner surface of the strip may be galvanized or copper plated. An iron strip may be applied to the sheath to improve its resistance to tension. To increase corrosion resistance a zinc alloy 5 per cent Al, 5 per cent Mg, having a lower electro chemical potential than the sheath is embedded in a protecting layer on the sheath and is electrically connected to both ends of the sheath. In an embodiment a communication cable comprises stranded cores 1, Fig. 4, a copper foil layer 15, a paper layer 16, steel sheath 7a, protecting layer 17, zinc alloy strip 18 and jute &c. layer 19. The corrugated sheath may form the outer conductor of a coaxial high-frequency cable e.g. having as an inner conductor a corrugated tube insulated from the outer conductor by e.g. discs.

Abstract: 772,279. Welding by pressure. MAGNETIC HEATINGS CORPORATION. Sept. 19, 1955, No. 26774/55. Addition to 748,528. Class 83 (4). [Also in Group XI] In welding the edges of a gap 11 in a metal tube 10, as claimed in the parent Specification, wherein the tube is advanced longitudinally and pressure is applied to close the gap at the welding point 12, the gap edges being heated by applying current to the tube by contacts 15, 16 which engage the tube at points on or near the gap edges and the current being of a frequency not less than 10 kilocycles per second and such that the lowest impedance path between the contacts follows the gap edges to the welding point, the impedance to current flow in paths circumferentially around the tube is increased by disposing magnetic material 50, 60 adjacent to such paths. The magnetic material may be arranged internally and/or externally of the tube and is preferably of high permeability. The tubing is fed to rollers 13, 14 where the gap is closed and welding effected at point 12. Current at frequency of 10,000-500,000 or more cycles per second is supplied to a block 21 carrying a contact 15 in sliding contact with one of the gap edges and flows along one edge of the gap to the point 12 and along the other edge to a further sliding contact 16 insulated from contact 15. Current flows from contact 16 along a hollow hair pin conductor 30 extending close to the edges of the gap and then to a block 22a. Additional insulated rollers ensure good contact with the contacts 15, 16 and a cooling fluid is circulated through the hair pin conductor. The hair pin conductor may be omitted. The magnetic material comprises rods 50, within the tube, of sintered magnetic oxide and insulation material or of laminated iron in an insulating band 52 supported by an insulating bracket 51 and rods 60 of similar material held in an insulating bracket 61 on the outside of the tube. The material within the tube may be of arcuate section positioned close to the tube wall. The contacts 15, 16 may be offset and contact either the inner or outer tube surfaces and a pair of insulated thin metal discs 62, Fig. 5, may enter the gap as spreaders.

Title: Improved process for desulfurization of gaseous streams
Inventor: SKARSTROM CHARLES WILLIAM
IPC: B01D53/04
Filed: 1963-07-08
Abstract: <PICT:0998501/C4-C5/1> In a cyclic process sulphur compounds are removed from a gaseous mixture by utilizing two adsorbent beds, the feed stream being passed at a higher pressure one way through the first bed in an initial cycle, discharging a desulphurized primary effluent and withdrawing a portion thereof, passing the remainder of the primary effluent in reverse flow through the second bed at a lower pressure to remove sulphur compounds adsorbed thereon giving a secondary effluent and before complete saturation of the first bed, reversing the functions of and gas flow through the beds. The secondary effluent may be desulphurized and subsequently combined with the primary effluent.  The adsorbent may be activated carbon, silver on "Doucil" (Registered Trade Mark), silver on ion exchange resins or molecular sieves, e.g. of 4, 5 and 13 <\>rA pore size.  In a specific embodiment, Fig. 1, crude oil is fed by pipe 2 to distillation zone 1 to yield a fraction boiling 100-450 DEG  F. at 4 which is cooled at 8 before passing to storage tank 9.  In the preferred embodiment, the hydrocarbon stream flows along 21, is vaporized at 22 and fractionated at 23. Zone 23 is an arrangement of two absorbent beds operating according to the invention which yields hydrocarbons free of sulphur compounds along line 24 and a mixture containing S compounds in line 25.  In one modification, the mixture is condensed at 26 and removed to be desulfurized by line 27, but it is preferred to pass the mixture by line 28 to hydrofining zone 12 after adding hydrogen.  Hydrofining zone 12 operates at 55 DEG  to 750 DEG  F. and 300-500 p.s.i.g. using cobalt molybdate on alumina as catalyst, and affords a mixture containing H2S which is condensed at 16.  The hydrocarbons free of H2S and H2 are removed at 17, whilst H2 and H2S are separated in zone 19, the H2S leaving at 20 and H2 being recycled by line 14.  Zone 19 is an arrangement of two adsorbents beds operating according to the invention.  In a modification, the hydrocarbon stream may be from tank 9 to the hydrofining step 12 by line 10 without the intermediate separation of hydrocarbons using zone 23.
