摘要： This invention concerns a line-laying device (10) used for platform mooring systems, consisting of two pairs of claws (11, 12) with twin hooks, swivelling about a spindle (13), one (12) of which claws is solid (at 18) where it swivels upon the spindle and is provided with a shoulder (19) engaged by a spring biased latch (20) provided with a small wheel (22) at its free end and mounted on said claw (11) by means of a spindle (23), said one claw (11) also being provided with a stop (24) to limit travel of said latch and with a ring (25) to which the cable to be dealt with is tied. This invention also covers a method of operating said line-laying device.

摘要： A process is described for the production of synthetic basestocks from an alpha-olefin feedstock with carbon number in the range C7-C30 the feedstock having origin in an ethylene polymerization process, the process comprising contacting the feedstock with a solid or soluble cationic AlCl3 catalyst. After separation and distilling out of the light fraction of the oligomer, a basestock of excellent viscometric, rheological and thermal stability properties is obtained. The basestocks so obtained are also described.
