Title: Improvements in or relating to the separation of xylene isomers
IPC: C07C7/152
Filed: 1952-12-17
Abstract: A feed containing m-xylene and at least one other isomer is mixed with a complex of BF3, an equimolar proportion of o- and/or p-xylene and at least an equimolar proportion of liquid HF, a hydrocarbon phase rich in other isomers and lean in m-xylene, and an acid phase comprising HF, BF3, and m-xylene are separated, and the acid phase distilled to separate the m-xylene.  The complex may consist of HF, BF3, and p-xylene, and the feed of o-, m-, and p-xylene, mixing being effected at from -50 to 120 DEG  F.  The amount of complex used is such that its content of p-xylene at least equals that of m-xylene in the feed. If it is desired to recover o-xylene in the hydrocarbon phase, the quantity of complex is such that its p-xylene does not exceed the m-xylene in the feed.  If it is desired to recover o-xylene in the acid phase, the quantity of complex is such that its p-xylene is at least equal to the sum of the m- and oin the feed. p-Xylene can then be recovered by fractional crystallization from the hydrocarbon phase as in U.S.A.  Specification 2,541,682.  If both m- and oare recovered in the acid phase, they are separated by fractional distillation or extraction with HF-BF3.  The complex used may, alternatively, contain o-xylene, obtainable by fractional distillation of mixed xylenes as in U.S.A. Specification 2,474,002 or by extracting m-xylene from a xylene mixture as in U.S.A. Specification 2,521,444.  The amount of complex used is then such that its o-xylene content is substantially equal to the m-xylene content of the feed.  The feed p  may consist of xylene fractions from various sources, e.g. from catalytically reforming naphthenic oils.  It is dried before counter-current extraction with the complex in a column or one or more mixer-settler combinations.  A p-xylene complex liberates p-xylene with formation of a m-xylene complex or a mixture of m-and ocomplexes.  These complexes are flash distilled to remove HF and BF3, which are again used to form complex, and to recover m-and o-xylene.  An o-xylene complex liberates o-xylene with formation of m-xylene complex.  The complexes used are prepared initially by mixing 1 mol. p- or o-xylene with 1-100 mols. HF, and introducing BF3 until 1 mol. is present in liquid phase. Specification 690,687 also is referred to.

Title: Improvements in or relating to the cooling and electrical insulating of electrical apparatus
IPC: H01F27/18
Filed: 1951-12-18
Abstract: 707,527. Cooling systems for transformers or like apparatus. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. Dec. 18, 1952 [Jan. 12, 1952], No. 32082/52. Class 64(3) [Also in Group XXXV] A transformer 16 enclosed in a sealed casing 12 is cooled by pumping an insulating liquid from a sump 24 up pipe 30 and through a spray 32 which distributes it over the transformer 16 which is cooled by evaporation of the liquid. Above the vapour filled space 33 is a body 34 of non- condensing gas such as nitrogen, argon, neon or carbon dioxide, the surface between gas and vapour moving up from position 40 to position 38 as the loading of the transformer, and consequently the vapour temperature, increases. At a level between positions 40 and 38, a tube 42 connects the interior of casing 12 to a manifold 44 at the bottom of a condenser 26. When the vapour level reaches this tube, some vapour flows down it and up the condenser where it cools and the liquid returns to the sump 24 by way of a pipe 46, which has a U-bend forming a vapour trap. Any non-condensing gas which enters the condenser 26 returns to the casing through an upper manifold 49 and tube 48. By this arrangement the temperature and pressure inside the casing are maintained substantially constant. This may be aided by the casing including a layer of heat insulating material 18 such as glass fibre. In a modification, Figs. 2, 3 (not shown), the tube 42 is replaced by a further condenser. The cooling liquid may comprise the liquid fluorinated organic compounds selected from the group consisting of hydrocarbons, hydrocarbon ethers and'tertiary hydrocarbon amines in which at least half the hydrogen atoms have been substituted by at least one halogen selected from the group consisting of chlorine and fluorine, and of which at least half of the halogen is fluorine. Suitable liquids are named and others are disclosed in Specifications 661,531, and 877,954.

[Also in Groups XXXVI and XL (c)] The output of a Hall effect device is connected to control, indicating or amplifying means and the semi-conductor body has a carrier mobility of at least 6000 cms<SP>2</SP>/volt sec. The Hall output may be applied to a valve, transistor or magnetic amplifier, a magnetic relay, or a controllable D.C. generator. Fig. 2 shows an arrangement which provides constant current through a load V. The Hall output from M is applied to a magnetic or other amplifier MV, the output of which varies inversely with the input which supplies the current through load V. This current also passes through coil EM to supply the magnetic field for Hall member M, and thus varies the Hall output so that a constant current then passes through load V and coil EM. A modification of the Fig. 2 arrangement is also described in which the load current passes through a servomotor which varies the position of a permanent magnet used to provide the magnetic field for the Hall member. Reference has been directed by the Comptroller to Specification 759,047, [Group XXXVI].
