Title: Underwater wellhead equipment
IPC: E21B33/038
Filed: 1972-01-10
Abstract: 1380971 Boring earth &c wells &c SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ NV 10 Jan 1972 1112/72 Heading E1F A tool for orienting an upper part (such as a marine riser 16) in 'a desired angular position with respect to a lower part consisting of 1 underwater wellhead equipment (a mandrel 10) comprises a guide string 14 and a sleeve 22 on the string. The riser is lowered adjacent the mandrel and the string and sleeve, connected by a pawl 54, are lowered through the riser until the sleeve lands on a seat 24. Continued downward movement of the string causes a bush 28 within the sleeve, and carrying the pawl, to drive dogs 30 carried by the sleeve into a groove 30 in the riser, and causes a key 34 on the string to enter a keyway 35 in the sleeve to angularly align sleeve and string. Rotation of the string permits a key 36 on the sleeve to enter a slat 33 in the riser to angularly align string and riser. The string is lowered until its bumper head 12 is 10-15 ft above the mandrel and the riser is lifted to expose a jet guidance nozzle which is 30 ft. above the head, the sleeve being clear of the key 34 so that the string may be rotated whilst a sonar detector 38 is used to guide the head into the mandrel. The string is lowered until a dog 42 on the head engages a groove 40 in the mandrel and the string is rotated until a key 44 on the head engages a slot 45 in the mandrel to angularly align the riser and mandrel. Immediately before the riser is lowered to lock it to the mandrel by hydraulically operated jaws 46, the key 34 leaves its slot to prevent damage to the electrical and hydraulic services when they are connected. The sonar detector is withdrawn through the string freeing the dogs 42 so that the string may be withdrawn from the riser. During withdrawal of the string the pawl, engages groove 52 to lift the bush to release dogs 30, and the keys 36, 44 are forced to retract. In a modification the key 34 is replaced by a slot in the string and the slot in the sleeve is replaced by dogs.

Title: Improvements in or relating to the manufacture of hydro-phenanthrene derivatives
Filed: 1947-01-13
Abstract: Octahydrophenanthrenes are prepared by reacting a 5 : 6 : 7 : 8-tetrahydroisoquinoline-halogenomethylate with a benzyl magnesium halide, hydrogenating the resulting 1-benzyl-2-methyl-hexahydroisoquinoline to the corresponding octahydroisoquinoline, and ring closing the latter by heating with phosphoric acid.  The benzyl magnesium halide has the formula <FORM:0620258/IV (b)/1> where one at least of X1 is a lower saturated alkyl or alkoxy group and the other symbols X1 are hydrogen or a lower saturated alkyl or alkoxy group.  The final 1-methyl-piperido-(21 : 31 : 41 : 9 : 14 : 13)-5 : 6 : 7 : 8 : 9 : 10 : 13 : 14-octahydrophenanthrene has the formula <FORM:0620258/IV (b)/2> where X is hydrogen or the same as X1, or the product of transformation thereof during the process, e.g. OH in place of OMe. In the examples, 5 : 6 : 7 : 8-tetrahydroisoquinoline-iodomethylate and -bromomethylate are prepared from 1 : 3-dihydroxy - 5 : 6 : 7 : 8 - tetrahydroisoquinoline by reaction with phosphorus oxychloride to give 1 : 3-dichloro-5 : 6 : 7 : 8-tetrahydroisoquinoline, followed by hydrogenation to 5 : 6 : 7 : 8-tetrahydroisoquinoline and treatment of the latter with methyl iodide or bromide.  The halogenomethylates are then treated with 3 : 4-dimethylbenzyl magnesium chloride and m- and p-methoxybenzyl magnesium bromides to give the corresponding piperido-octahydrophenanthrenes after hydrogenation followed by ring - closure.  When present, the bulk of any methoxyl group is hydrolysed to hydroxyl in the final cyclization with phosphoric acid. According to the Provisional Specification, this hydroxyl group may be remethylated with methyl sulphate.

Silvering.-A machine for use in withdrawing liquid from the annular chamber in doub1e-wa11ed vacuum bottles, and particularly the water emp1oyed tor rinsing after the si1vering process, is provided with two tanks for receiving the liquid and with mechanism operab1e to connect the bott1es with a vacuum pump through the tanks a1ternate1y so that whi1e one tank is receiving the liquid the other can be emptied. The bottles 17, Figs. 1 and 3, are mounted on stands 19 and the vacuum chambers are connected by air-tight connections 15 to pipes 12, 13 arranged above the table 10 of the machine. The pipes 12, 13 are connected by tubes 32, 33 to a passage 27, Fig. 6, in a s1ide. 22 guided in a b1ock 21 secured to the tab1e. The slide 22 is also provided with a passage 25 adapted to be connected by a tube 30 to the vacuum pump, and with air-vents 26, 26<1>. Passages 34, 36 and 35, 37 in the block 21 are connected respective1y to the tanks 38, 39 mounted be1ow the tab1e. The tanks are provided with drain-pipes 42 contro11ed by va1ves that c1ose when the tanks are connected to the pump but open automatically when atmospheric pressure is re-established. When the passage 25 in the s1ide 22 registers with the passage 34, the passages 27, 36 also register so that the liquid can be withdrawn by the pump into the tank 38. At the same time the passage 35 registers with the airvent 26, so that the tank 39 is open to the atmosphere to permit the liquid therein to drain away through the pipe 42. Movement. of the slide 22 brings the passages 25, 27 into register with the passages 35, 37 to withdraw the liquid into the tank 39, and the vent 26<1> into register with the passage 36 to permit the draining of tank 38. The slide 22 is actuated by a be11-crank lever 45, Fig. 3, connected to a piston 53 working in a cy1inder 51 having pipes 57, 58 at its ends connected with apertures in a stationary disc 59. Other apertures in the disc 'are connected by pipes 60, 61 to the vacuum pump. A continuous1y-rotating valve disc 62, pressed into air-tight contact with the disc 59 by a spring 64, is provided with a recess 66 and an aperture 67, Fig. 4. From the position shown in Fig. 3, rotation of the disc 62 results first in connecting the pipes 57, 60 by the recess 66, and the connection of the pipe 58 to the atmosphere through the aperture 67 so that the piston 53 rises in the cy1inder 51 and actuates the slide 22. Continued rotation of the disc 62 interrupts the commmication between the pipes 57, 60, and the piston remains at the upper end of its stroke until the recess 66 connects the pipes 58, 61 and the aperture 67 registers with the pipe 57, when the piston and slide are returned.
