Abstract: 1,146,860. Polyalkylcyclopentadienes. BP. CHEMICALS (U.K.) Ltd. 18 Sept., 1967 [12 Oct., 1966], No. 45633/66. Heading C5E. Polyalkylcyclopentadienes are produced by reacting an olefin having at least 4 carbon atoms with strong mineral acid, e.g. H 3 PO 4  or H 2 SO 4 , and are recovered by extraction with an inert water-immiscible solvent, e.g. cyclohexane or perchloroethylene. The starting material is suitably a C 4-20  acyclic olefin, e.g. an oligomer of ethylene, propylene or n-butene, exemplified by propylene trimer and propylene tetramer. The reaction is believed to involve dimerization of the olefin, transfer of two hydrogen molecules from the dimer to two molecules of monomer, and cyclization of the dimer. Skeletal re-arrangement may occur at any stage in the process. Suitable reaction temperatures are - 10 to +50‹ C. and the reaction may take place simultaneously with the production of neoacids as described in Specification 1,120,714

Abstract: 938,025. Polishing. BELL INTERCONTINENTAL CORPORATION. Dec. 22, 1961 [May 1, 1961], No. 46001/61. Class 60. A method of polishing surfaces by projecting particles of resilient material on to said surfaces with a motion having a linear component and a rotational component comprises feeding the particles between opposed surfaces moving in opposite directions with one surface having a higher rate of surface speed than the other surface, and positioning the surface to be polished in the path of the particles thrown from between the surfaces. Rollers 20, 22, Fig. 1, have their peripheries spaced apart by a distance equal to the crosssection of the resilient pallets 30 and are rotated in the same angular direction. The roller 20 is rotated faster than the roller 22. In a modification the roller 22 is of smaller diameter than the roller 20, the rollers being driven at the same angular rate. In a modification, Fig. 3, the pellets pass between belts 40, 42, the opposed runs moving in opposite directions, and the run which moves towards the work 32 travelling faster than the opposed run. One of the belts may be replaced by one or more rollers. In a modification, Fig. 5, the pairs of pulleys round which the belts pass have their axes non-parallel, e.g. at right angles. The rollers and belts may be roughened and grooved. A further modification, Fig. 6, has a cone 80 and a conical shell 84. One of the conical surfaces, preferably that of the shell, has a higher linear speed than, and rotates oppositely to, the other conical surface. Directional control of the pellets thrown from between the members may be effected by a rigid member having a slight spiral shape and located adjacent the outlet. Paraboloids or hyperboloids may be used instead of cones. Specification 884,942 is referred to.

Title: Improvements in or relating to electrical conductors and processes for producing thesame
IPC: H01B7/02
Filed: 1964-11-17
Abstract: An electrically insulating resin composition comprises from 20 to 60% by weight of an esterimide resin and from 80 to 40% of a linear polyalkylene ester of isophthalic and/or terephthalic acid, dissolved in a mixture of phenols and cresols.  The composition may be produced by adding 5-10% of an alkylene polyester, at elevated temperature, e.g. 90 DEG  C., to a 3-8% solution of the polyesterimide in the solvent, any water present being then removed by azeotropic distillation with xylene.  In Example (1) a polyester is produced by heating dimethyl terephthalate, glycerol and ethylene glycol in the presence of cerium naphthenate, calcium naphthenate and cresol. Trimellitic anhydride and bis-(4-aminophenyl) methane are then added and heating continued, first to produce bis-(4-trimellitimidophenyl) methane and then to polymerize it.  Butyl titinate, p-toluene sulphonic acid, naphtha and xylene were added to the resulting solution to produce an insulating varnish.  Another varnish was produced in Example (3) by adding poly-(glycol terephthalate) chips, phenol and further cresol and xylene to the product of Example (1) and distilling off all the xylene.ALSO:An electrical conductor has an electrically insulating coating consisting of an inner insulating layer constituted by an ester-imide resin and superimposed thereon an outer insulating layer constituted by a combination of a cross-linked esterimide resin with a linear polyalkylene ester of isophthalic and/or terephthalic acid.  The preferred linear ester is a glycol terephthalate.  The resins are applied in an example to copper wire. The first layer is applied by known processes, and the coated wire then passed once or more through a heated solution of the mixed resins, and finally stoved.
