Abstract: 1,237,550. Detergent alkylate. UNIVERSAL OIL PRODUCTS CO. 14 Nov., 1968 [15 Nov., 1967], No. 54077/68. Heading C5E. Linear detergent alkylate is produced by a process comprising the steps of (a) catalytically dehydrogenating an n-paraffin feed in the presence of hydrogen, (b) using the resulting monoolefins to alkylate a monocyclic aromatic, particularly benzene though others are mentioned, (c) separating the alkylation zone effluent to produce required product and an unchanged n-paraffin fraction for recycle to (a), and (d) before said recycling, treating at least part of the n-paraffin fraction to remove non-normal hydrocarbons therefrom such that the concentration of n-parafhns in the n-paraffin fraction is at least 90 wt. per cent. Suitable dehydrogenation catalysts comprise alumina, an alkaline component, a platinum group metal component and a component selected from As, Bi, Sb, S, Se, Te and compounds thereof. Hydrogen produced in (a) is separated and recycled. Conventional alkylation catalysts are used in (b), preferably HF. Step (d) may be carried out by molecular sieve absorption in a simulated counter-current operation, and if the feed to (a) contains non- normal hydrocarbons this may also be passed through the same absorption step. The use of step (d) lessens catalyst deactivation in step (a), and aids maintenance of the quality of the alkylate product.

Title: Method of and apparatus for working on wells
Inventor: CROSS ROBERT V
IPC: E21B33/072
Filed: 1965-12-21
Abstract: 1,107,493. Reels. CHEVRON RESEARCH CO. 21 Dec., 1965 [24 Dec., 1964], No. 54209/65. Heading B8M. [Also in Divisions E1 and G3] The end of a pipe 30 from a reel 40 extends as a free arc into a pipe injector 18 which feeds tube into a well 14, and means are provided, to maintain the arc between predetermined limits of curvature to prevent kinking and stretching of the pipe. The variations in the slope the pipe adjacent the injector and reel are sensed by devices 50, 60 connected to a regulator 80 which controls the flow of actuating fluid to the drives of the injector and a feed mechanism 70 at the reel, the arrangement keeping the rate of the feeds substantially equal. The mechanism 70 comprises friction-drive wheels engaging the pipe and includes adjustable rollers 76 for straightening and slightly flattening the pipe as it comes off the reel. The device 60 and the mechanism are manually movable on a beam 84 parallel to the axis of the reel to align the pipe. The reel is frictionally driven by a manually controlled motor 93a so the speed of pipe leaving the reel corresponds to that of the pipe at the mechanism. The rate of parallel movement of the mechanism and the speed of the reel may be synchronized. The sensing device 60 has spring-loaded rollers 61 engaging the pipe and carrying cores (64, Fig. 8, not shown) movable in windings (65) to generate a voltage which is amplified and supplied to the control winding (171) of a motor adjusting a valve 173 controlling flow of fluid to a motor 72 driving the mechanism 70. In a modification (Figs. 4 . . . 7, not shown) a reel (140) is mounted on a vertical axis on a barge and has fingers 130 to hold the upper outer turns of the pipe as it is taken from the bottom towards the top of the reel. The reels have means for supplying treatment fluid to or removing fluid from the pipe and well. The feed from the reel only may be controlled to maintain the arc's curvature and the control of the feeds may be manual.

Title: Apparatus for forming reserve windings
IPC: B65H54/71
Filed: 1974-12-17
Abstract: 1470450 Apparatus for forming reserve windings MASCHINENFABRIK RIETER AG 17 Dec 1974 [17 Dec 1973] 54371/74 Addition to 1408670 Heading D1J The invention relates to a modification of the invention set forth in claim 8 of Specification 1408670 and is characterized in that a yarn-retaining means 97 is mounted on the pivotal support 12 instead of the previous yarn severing means the yarn-retaining means 97 as it is lowered holding the yarn fast between a suction unit 85 and the bobbin tube. When the package 5, Fig. 11, reaches its desired diameter the package support 12 is raised to lift the package 5 off its drive roller 6. A loop of yarn extending between the package 5 and supply rollers 4 is then fed by hand into the suction opening 85. The yarn leading to the package 5 is then cut, and the package 5 replaced by an empty bobbin. As the support 12 is lowered to move the empty bobbin into engagement with the drive roll 6 a resilient bottom edge 98 of the yarn retaining means 97 traps the yarn 3 against a side 93 of a guide plate 91. The guide plate 91 has a notch 95 in which the thread runs before being clamped, the notch 95 being aligned with an adhesive zone extending around one end of the bobbin. When the pivotal support 12 is lowered to cause the yarn passing into the suction opening 85 to be trapped between the edge 98 and the side 93 of the plate 91, a loop of yarn builds up under the adhesive zone of the new bobbin since the supply rollers 4 continue to feed yarn. In this way, the yarn loop is picked up and held fast by the adhesive zone at one end of the bobbin. When the yarn has been adequately looped around the tube, the yarn breaks between the tube and the point at which it is held. The following windings form a reserve winding which tucks in the short free end. The yarn is then manually threaded into a traverse guide and normal package winding commences.
