Abstract: 1,116,878. insulating cable joints; joining cable shields; cable terminations. RAYCHEM CORPORATION. 10 Aug., 1965 [10 Aug., 1964], No. 34183/65. Heading H2E. [Also in Division F2] A member of material having the property of elastic memory and in distorted, heatrecoverable form or an elastomer frozen in a distorted condition, or held in distorted condition by a fusible member, is associated with a grease, mastic or other non-crystalline material having a viscosity not greater than 10<SP>13</SP> centipoise at 25 C., and is used for sealing, coating and like purposes. On the application of heat, the member restores to its original size and shape and causes the grease or the like to form a seal between itself and an article around or within which it has been arranged. A cup -shaped member containing a silicone grease may be used to terminate a cable or seal a stub joint between electric cables, and such a member containing a fluorocarbon grease incorporating finely divided copper flakes may be used in order to reduce corona effects. Such effects may be reduced at a cable joint by applying a tubular member with a lining of hydrocarbon grease containing finely divided lead, copper and graphite flakes, and a tubular member lined with a silicone grease incorporating graphite may be used to make a sealed connection between the braids of jointed cables. Tubular members may also be used to seal pipe joints or line tubes (see Division F2), and cup-shaped members to deliver predetermined quantities of liquid (see Division B8). The latter members may be used with mercury, low-viscosity waxes and solvents.

[Also in Division C5] Pyromellitic acid and its mono- or dianhydride are obtained by a process comprising the steps of dimerizing propylene to 2,3-dimethylbutene, dehydrogenating the dimerization product, if desired, after isomerization to 2,3- dimethyl - 1,3 - butadiene, reacting the dehydrogenation product with maleic anhydride by the Diels Alder reaction to form dimethyl - tetrahydrophthalic acid anhydride and obtaining pyromellitic acid or its anhydrides therefrom by dehydrogenation and oxidation, followed if desired, by an appropriate hydrolysis step. The dimerization of propylene may be carried out according to the process of Specification 1,058,680 with catalysts based on #-allyl-nickel-halides activated by Lewis acids and suitable electron donors, e.g. strong basic phosphines. Catalysts for use in the isomerization step include ptoluene sulphonic acid and iodine. The dehydrogenation of the dimethyl butene is carried out catalytically and of the Diels-Alder product either catalytically or by stoichiometric reaction with dehydrogenating reagents, e.g. by heating with sulphur or with chloranil or bromine. Oxidation and dehydrogenation of the Diels Alder product may be carried out simultaneously with oxygen containing gases in the presence of catalysts consisting of vanadium pentoxide optionally together with other metals or oxides, e.g. TiO 2 . The examples relate to the preparation of pyromelltic acid and the dianhydride. #-Allyl-nickel halides are obtained by reacting anhydrous nickel halides with an alkyl aluminium in the presence of butadiene and reacting the bis-#-allyl compound with hydrogen halides.
