Title: Improvements in or relating to welded joints for pipes, cylinders or the like
IPC: F16L13/02
Filed: 1937-06-01
Abstract: 496,293. Pipe joints. BAILEY, R. W., and METROPOLITAN - VICKERS ELECTRICAL CO., Ltd. June 1, 1937, Nos. 15242 and 32419. [Class 99 (i)] [Also in Group XXII] A welded circumferential joint between the abutting end surfaces of the walls of pipes is reinforced by external sleeves or collars which are secured to the outer longitudinal surfaces of the pipes so as to prevent relative axial movement and are welded at their adjacent ends. The welded joint 3 between pipes 1, 2, may be made over a liner 4, which may be welded to the pipe 1 at 5. The sleeves 7, 9 may be secured on the pipes by buttress screw threads 6, 8, Fig. 1, by a series of co-operating circumferential grooves and rings, or may be welded at each end 20, 19, 21, 22, Fig. 4, to the pipes 1, 2. When connected by screw threads or grooves, the adjacent end of either or both sleeves may be welded at 15 to the pipes so as to provide good thermally conducting connections therebetween. One or both sleeves may be integral or consist of a series of axial segments which may be welded together at 10, a protecting strip 11 being inserted in a recess 12 for separating each weld from the screw thread 8. The sleeve 9 may be welded direct to the sleeve 7 at 14 or may be welded thereto at 26, 27 through an interposed member 23, Fig. 4, formed in one piece or of a series of axially welded segments. In the former case, Fig. 1, the collar 9 may have a portion 13 of reduced radial width, which provides elongated apertures 16, Fig. 2, over the joint 3 to detect any escape of steam through the joint 3. The apertures may be provided with lengths of tube so as to bring the inspection points outside the pipe lagging. In a modification, lengths of pipe may be screwed or otherwise fixed through the sleeve for this purpose. When an interposed member 23 is used it may be placed on circular or segmental packing strips 24, 25 to locate it at the required distance from the pipes. Such members may contain the apertures. In the form shown in Fig. 1, the pipes 1, 2 may be of steel containing 0.5 per cent of molybdenum having high creep resistance but low ductility under such conditions and the parts 7, 9 and the welds may be of mild steel which has a high ductility under creep conditions and has practically the same total thermal expansion as the alloy steel at any operating temperature over a range 750- 1000‹ F. so as to avoid stress effects due to differential thermal expansion. Layers of mild steel weld metal 18 may be applied to the ends of the pipes before effecting the weld 3. The form shown in Fig. 4 may be applied to pipes of mild steel.

Filed: 1975-04-17
Abstract: 1456189 Apparatus for winding side-by-side windings MESSER GRIESHEIM GmbH 17 April 1975 [20 April 1974] 15883/75 Heading D1J Side-by-side turns of wire are wound on a flanged drum 36, Fig. 6, by means of a sliding carriage 60 that is traversed by a friction wheel 82 pressing against a drive cylinder 52. The friction wheel 82 is carried by a shaft 68 that extends through the carriage 60, the shaft 68 carrying a control lever 76 with yarn guide means 78 at its free end. At the upper end of the shaft 68 is a yarn guide pulley. In operation, Fig. 5, the yarn 18 passes over the pulley 74 and onto the drum 36 via the guide means 78 at the end of the lever 76. Assuming that the turns are being laid on the drum 36 from left to right this will cause the lever 76 to first lag on the turns being laid and to then swing slightly to the right, thus causing the friction wheel 82 to turn through a corresponding angle. The resulting inclination of the axis of the friction wheel 82 to the axis of the drive cylinder 52 will cause the carriage 60 to move from left to right. When the layer of windings is completed, the wire abuts against an end flange of the drum 36, jumps up to the level of the next layer and commences to be wound up from right to left. This causes the lever 76 to be tilted to the left and, as a result of the new inclined setting of the axis of the friction wheel 82 to the drive cylinder 52 causes the carriage 60 to traverse to the left also. The drive cylinder 52 may be of cast steel or grey cast iron, and the friction wheel 82 of plastics material or hard rubber.

Title: A process for alkylating hydrocarbons
IPC: C07C2/54
Filed: 1958-05-19
Abstract: The alkylation of paraffinic hydrocarbons or aryl substituted derivatives thereof or fully or partially hydrogenated cyclic hydrocarbons with an olefine is effected by treating a reaction mixture containing at least one mol. of hydrocarbon to be alkylated per mol. of olefine with 0.1-5 mols. per cent, based on the total hydrocarbon, of one or more hydrosulphuryl compounds and/or organic disulphides at at least 200 DEG  C. and below that temperature at which substantial thermal cracking of the hydrocarbons occurs and at least 45 kg./cm.2 gauge.  Oxygen in an amount of 0.05-5 mols. per mol. of sulphur compound may also be present, but not in excess of 5 mol. per cent based on total hydrocarbons.  The carbon atom which is alkylated is generally that carrying most substituents; in aryl alkanes or arylcycloalkanes, the alkyl group is alkylated.  The hydrocarbon to be alkylated may be a normal or branched chain alkane of 3 or more carbon atoms, a non-olefinic cyclic hydrocarbon such as cyclopentane and cyclohexane or their alkyl derivatives, decalin, tetralin, or an alkyl or polyalkylbenzene or naphthalene; waxes can also be alkylated.  The olefine preferably has 2-5 carbon atoms and is preferably non -conjugated and particularly mono-olefinic.  The molar ratio of hydrocarbon to be alkylated to olefine is preferably between 2:1 and 10:1.  The sulphur compound may be H2S or an organic alkyl or cycloalkyl mercaptan, thiophenol or dialkyl, dicycloalkyl or diaryl di -sulphide of which many are specified, or their drivatives such as thioacids (R-CO-SH), mercapto-carboxylic acids (HS-R-COOH), substituted thiophenols (p-methoxy- or pentachloro - thiophenol), 2 - mercapto - benzothiazole, diacyldisulphides and substituted dialkyl disulphides such as dithioglycollic acid.  Mixtures may be used such as are recovered in the extractive sweetening of petroleum distillates.  They may be solid, liquid or gaseous but are preferably such that they exist in the same phase as the reactants under alkylation conditions.
