Title: Centering device for welding ends of pipe
IPC: B23K37/053
Filed: 1959-09-24
Abstract: 929,997. Welding by fusion. KRAFTANLAGEN A.G. Sept. 24, 1959 [Sept. 24, 1958; Aug. 5, 1959], No. 32498/59. Class 83 (4). A centring device for use in the buttwelding of pipes consists of two expandable clamps arranged to engage the inner surfaces of the pipes, one of the clamps being pivotally secured to the other. Each clamp has sectors 1, 5, Fig. 1, guided in channels 14, 15 and connected by links 2, 6 to pistons sliding in hydraulic cylinders 3, 7 respectively. A frame 25 carrying the channel 14 and secured to the cylinder 3 is universally pivoted to a frame 21 secured to the cylinder 7. The channel 15 which is slidably mounted on the cylinder 7 carries bolts 10 surrounded by springs 8 and engaging in the channel 14 to initially maintain the channels 14, 15 parallel. In operation, the right-hand clamp is inserted in the pipe 4 and pressure liquid is supplied to the cylinder 3 to force the sectors 1 against the pipe. Spacers consisting of steel strips radially movable relative to and mounted on the sectors 1 abut the end of the pipe 4. The pipe 11 is superposed over the left-hand clamp which is expanded. Further supply of pressure liquid to the cylinder 7 causes the clamps to move together until the pipe 11 abuts the spacers. After a root weld has been formed the cylinders 3, 7 are exhausted and the clamps are released by a compression spring 26. If desired the sectors may form an elliptical configuration for use in the process described in Specification 760,504. In a modification, the sectors 43, 44, Fig. 5, connected by links 51, 52 to the frames 53, 54 of the clamps are linked to nuts 50, 49 on oppositely threaded rods 46, 45, ball-jointed together and journalled in the frames 53, 54. Upon rotation of the rods 46, 45 manually or by an adjacent or remote electric motor, the sectors 43, 44 are extended until the latter engage the pipe 41. At the same time spacers 60 on arms 61 held by springs 62 against the sectors 41 are extended by links 63. The clamps are held parallel initially by springs 65 on bolts 64 passing through the frames 53, 54. After the pipe 42 is placed in position the sectors 44 are further extended by rotation of the rods 45, 46 which as the nut 50 is now fixed move axially against the action of a spring 66 to pull the pipes 41, 42 together. After the root weld has been made, reverse rotation of the rods 45, 46 releases the sectors 44. When a thrust bearing on the end of the rod 46 engages the frame 53 the spacers 60 and the sectors 43 are withdrawn. Alternatively, the spacers 60 may be hydraulically actuated and the aligning bolts 64 and springs 65 may be replaced by spring- loaded rods mounted in the sectors 44 and engaging the spacers 60. The spacers and sectors may also be actuated pneumatically or electromagnetically.

Title: Improvements in the manufacture of artificial filaments, yarns, ribbons and the like
IPC: D01F2/28
Filed: 1929-10-26
Abstract: Cellulose esters and ethers; apparatus for making filaments.-In the wet-spinning of solutions containing organic derivatives of cellulose, the spinning solution is maintained at a temperature above that of the spinning bath whereby more concentrated solutions may be spun and smaller jets may be employed.  Fine filaments of 1-10 denier or heavy filaments up to 20 or 2000 denier or higher may be produced e.g. for the manufacture of brushes, braids, artificial furs, &c. The solutions may comprise esters such as cellulose acetate, formate, propionate or butyrate and ethers such as methyl, ethyl or benzyl cellulose dissolved in acetone, acetone-water, acetone and methyl or ethyl alcohol, ethylene or methylene dichlorides or mixtures of ethylene or methylene dichloride with ethyl or methyl alcohol. Coagulation is effected in a suitable non-solvent liquid which is at least partially miscible with the solvent or with a constituent of the solvent mixture; kerosene, gasoline, mineral lubricating oils or other mineral oils and olein, castor or other vegetable oils are specified.  The spinning solution may be maintained at the desired temperature by heating the pipe-line leading to the spinning jet or nozzle by means of steam or hot water coils or jackets, or electrically.  The coagulating bath may also be heated e.g. by internal coils or external heaters.  The filaments &c. may be wound on to a bobbin situated in the coagulating bath.  Heavy filaments, e.g. of 1000 denier are spun at low speeds e.g. 1-2 metres per minute.  In examples (1) a solution of cellulose acetate dissolved in 95 per cent aqueous acetone maintained at 45 DEG  C. is extruded through circular orifices 0,08 mm. into a coagulating bath of kerosene maintained at 25 DEG  C., the rate of spinning being 50 metres per minute and the length of immersion 12-16"; (2) a 25 per cent solution of cellulose acetate in a 60/40 mixture of ethylene dichloride and methyl alcohol maintained at a temperature of 55 DEG C. is similarly spun into kerosene maintained at a temperature of 30-35 DEG  C.  The Specification as open to inspection under Sect. 91 (3) (a) describes also the production of finer deniers by raising the temperature of the coagulating bath, and also includes the subject-matter of Specification 341,388.

Abstract: 1,065,565. Sewing machines. SINGER CO. July 31, 1965, No. 32878/65. Heading DIG. A zig zag sewing machine comprises dual eccentric means mounted on a driven shaft and connected to the needle bar gate for vibrating the latter, the arrangement being such that dwell periods occur in the vibration while the needle is penetrating the work. As shown, the needle bar 30 is mounted in a gate 32 rigid with a rod 33 slidable axially in bearings 34, gate 32 being engaged on each side by a fixed pin 35. Two eccentrics 50, 51 are rigid with a shaft 52 driven by 2 to 1 reduction gearing from the arm shaft 20. The eccentrics are embraced by respective straps 55, 56 pivoted at 58 and 59 respectively to an integrating link 57 pivoted at 62 to an arm 61. One end of the latter is pivoted at 63 to a bracket 64 rigid with rod 33. The other end is pivoted to a pin slidable on a substantially vertical rod 68, Fig. 2 not shown. The amplitude of vibration and the neutral position of gate 32 are respectively determined by the inclination of rod 68 and the position of the latter along the longitudinal axis of the machine. Rod 68 is fixed in a frame 69 having a lateral pin journalled eccentrically in a sheave 80 journalled eccentrically in a sheave 81 which is journalled in the machine frame. A block 90 pivoted on sheave 80 is slidable in a slot 91 in a fixed bracket 87. Sheave 81 is rotated by means of a handle 83 for varying the longitudinal position of rod 68. Bracket 69 is pivoted to a block 102, Fig. 2, slidable in a groove formed in a member 101 supported by two parallel pivoted arms 103, 104. A handle 100, rigid with arm 103, may be turned for varying the inclination of rod 68. The geometrical centres of the eccentrics 50, 51 are spaced at 80 degrees apart about shaft 52. The plane through shaft 32 and pivot 63 is perpendicular to the plane through shaft 52 and pivot 62. The distance between the geometric centre of each eccentric 50, 51 and its associated pivot 58, 59 is 2.25 times the eccentricity of the eccentrics. The distance between the pivots 58, 59 is 2.5 times the eccentricity, and the height of an isocells triangle defined by the pivots 58, 59, 62 is 2.8 times the eccentricity. The arrangement is thereby such that link 57 turns about 62 without raising arm 61 to shift gate 32 while the neddle is engaging the work.

Abstract: 760,818. Making longitudinally seamed tubes for coaxial cables; corrugating. BRITISH INSULATED CALLENDER'S CABLES, Ltd. Nov. 29, 1954 [Nov. 27, 1953]. No. 33004/53. Classes 83 (2) and 83 (4). A device for corrugating the edge of a metal strip comprises two intermeshing rings of rods between which rings the edge of the strip is fed, the rods of one ring being inclined to the rods of the other ring where they intermesh. Metal, e.g. copper, strip 2 is drawn by a pair of rollers over guide means and through a corrugating device which serves to corrugate or crimp the strip at its edges. The corrugating device comprises a pair of co-operating mutually-inclined rings 8, 9 of rods 12 corrugating one edge of the strip and similar pair of rings 10, 11 corrugating the other edge. The rings of rods of each pair intermesh and the rods 12 of the lower rings 9 and 11 of the two pairs are further extended to intermesh so that as the strip 2 is pulled between the rings of rods the rings rotate about their shafts 16 in synchronism with one another, the corrugations formed on one edge of the strip being 180 degrees out-of-phase with those on the other edge. The rings of rods are mounted on their shafts 16 in bearing-blocks 18 adjustable to and from one another for varying the length of the corrugations. In a modified form of corrugating device, Fig. 6, the shafts 16 are parallel with one another and the rods 12 of each ring are inclined relative to their shaft 16 to lie on the surface of a cone. To form a tube for, for example, the outer conductor of a coaxial cable, the strip is bent up so that its corrugated edges abut.
