Title: Isolation of gamma benzene hexachloride
IPC: C07C17/38
Filed: 1954-06-03
Abstract: A method for separating the gamma isomer from a mixture of isomers of benzene hexachloride comprises extracting a feed supply of benzene hexachloride mixed isomers at a temperature of at least 60 DEG  C. to remove substantially all of the gamma isomer therefrom with an extractant consisting essentially of a solution of from 60 to 35 per cent by weight of a solute consisting essentially of benzene hexachloride isomers in such proportion that the solution contains from 12 to 17 per cent gamma isomer and from 8 to 18 per cent delta isomer, by weight, and correspondingly from 40 to 65 per cent of a volatile medium which is substantially methanol or ethanol, the solution being used in an amount to provide from 0.5 to 2 times as much of the volatile medium as the total weight of benzene hexachloride present in the extraction zone, and separating the soformed solution containing substantially all of the gamma isomer from the undissolved portion consisting chiefly of alpha isomer at a temperature from 40 DEG  to 60 DEG  C. when the volatile medium is methanol, and at 10 DEG  to 15 DEG  C. higher temperature when it is ethanol.  The feed supply of benzene hexachloride mixed isomers is heated in an initial extraction zone with from 0.5 to 1.5 times its weight of methanol or ethanol to a temperature of at least 60 DEG  C. at which substantially all of the gamma isomer is dissolved, the resulting slurry is stirred and cooled to a temperature of 55 DEG  to 60 DEG  C. at which the gamma isomer remains in solution while most of the alpha isomer is in the solid phase, the slurry is filtered to remove a solid fraction rich in alpha isomer, the filtrate is stirred and cooled to 35 DEG  to 45 DEG  C. and filtered to recover gamma isomer crystals of at least 90 per cent purity, the so-filtered mother liquor being returned to the initial extraction zone in contact with more of the mixed isomers and with enough additional solvent to maintain the solvent ratio, and the series of operations repeated, enough of the mother liquor being withdrawn from the system periodically to maintain the concentration of delta isomer therein. The mother liquor which is withdrawn is chilled to separate a fraction rich in gamma isomer, which is filtered off and added to the benzene hexachloride feed. Examples of the process are given. Specifications 573,693, 680,955, 686,354 and U.S.A.  Specifications 2,574,165 and 2,585,898 are referred to.

Filed: 1938-06-07
Abstract: 511,637. Converting ; changing wave form. FORSSELL, H., and ALLMANNA SVENSKA ELEKTRISKA AKTIEBOLAGET. June 7, 1938, No. 16920. [Class 38 (ii)] In a current converter system comprising a grid-controlled valve, alternating voltage of rectangular wave form for application to the grids is derived from the A.C. terminals of a full wave rectifier arrangement to which a sinusoidal voltage is applied and across the D.C. terminals of which a constant D.C. voltage is impressed. In the arrangement shown in Fig. 1 in which an oscillatory circuit 7, 8 is energised from a D.C.' source 10, superposed voltages derived from a current transformer 11 and a voltage transformer 12 are applied to the A.C. terminals of a bridge arrangement of rectifiers 18 across the other diagonal of which a D.C. voltage source 19 is connected so that the bridge becomes conductive only when the input A.C. voltage in the conductive direction exceeds the opposed D.C. voltage. The rectangular voltage wave thus produced at the A.C. terminals is applied to the grids 4, 5. In a modified arrangement, Fig. 4, in which the oscillatory circuit 7, 8 is fed from a polyphase source of A.C. 42 through a transformer having two secondary windings 40, 41 associated with two groups of anodes operating alternatively, the corresponding groups of grids are connected to opposite sides of a pair of rectifiers 20, 21 to which the superposed voltages. from the transformers 11, 12 are also applied. The D.C. voltage effective to maintain the rectifiers 20, 21 non-conductive until the input A.C. voltage exceeds a predetermined value is in this case provided by an auxiliary rectifier group 22. In all the arrangements regulation may be effected by adjusting the magnitude and/or phase of the input A.C. voltages as by a resistance 13 and inductance 14.

Patent GB-889617-A (GB)
Title: Process for the manufacture of coloured shaped structures of linear aromatic polyesters
IPC: D01D1/06
Filed: 1958-05-29
Abstract: Particles of linear aromatic polyesters, especially polyethylene terephthalate, are mixed with a pulverulent or granular concentrate containing a colouring matter finely dispersed in a linear polyester or copolyester which contains aromatic groups, has a molecular weight above 18,000 and a melting point above 150 DEG C., is soluble in a solvent boiling below 100 DEG C., and does not decompose at the melting point of the firstmentioned linear aromatic polyester, and the mixture is shaped in known manner into filaments, ribbons, monofils or foils.  The acid component of the copolyester used to make the concentrate may consist for the greater part of terephthalic acid.  The concentrate may be made by dissolving the polyester or copolyester in a solvent boiling below 100 DEG C., subsequently dispersing a pigment dyestuff of fine particle size in the solution so made, and then evaporating the solvent, while stirring. Alternatively, a dispersion of a dyestuff in an aqueous medium may be flushed from the aqueous phase into an organic solvent in which the polyester or copolyester used for making the concentrate has been or is subsequently dissolved, and the solvent evaporated from the solution to form the concentrate.  A mixture of the particles of uncoloured linear aromatic polyester and the pulverulent or granular concentrate may be extruded to form a rod or narrow ribbon, which is then cut into small pieces and melt-spun.  In examples, polyethylene terephthalate is mixed with concentrates containing, as colouring matters, carbon black, the dioxazine dyestuff made from 1 mol. of chloranil and 2 mols. of 3-amino-N-ethylcarbazole, a dyestuff made by condensing Bz-1-bromo-benzanthrone with pyrazole-anthrone and subjecting the product to alkaline fusion, and a copolyester made from 70 parts of dimethyl terephthalate, 30 parts of dimethyl isophthalate and the equivalent quantity of ethylene glycol, the solvent used being methylene chloride or ethylene chloride.  Other specified colouring matters include iron oxide, cadmium pigments, ultramarine, phthalocyanines, vat dyes and anthraquinone derivatives. Specification 651,694 is referred to.

Assembling matrices.-In a typographical line-composing machine including a locking device for preventing rise of the assembler elevator, means for releasing the locking device to permit rise of the elevator, and a control device operated by the assembler slide to actuate the release means when the slide has moved such a distance that the composed line thereon is of the desired predetermined measure, the release means comprises a solenoid, and the control means comprises a normally-open switch in circuit with the solenoid, and a rider carried by the slide to close the switch when the line is of the desired length. When a line has been assembled in the assembler elevator B, the assembler slide brake 9 is momentarily released to allow the spring 8 to retract the slide 7 'to remove any slack in the line, either by manual depression of a lever 20, or by the action of a rotary solenoid 21 on said lever, if the machine is under automatic control, when a switch 24 is closed by a cam 22 on the power-driven shaft 15 which raises the elevator when the requisite signal is received. The elevator B is raised through links 13, 14 either manually by a lever, or from the shaft 15 which operates said lever if the machine is under automatic control. The elevator is, however, prevented from rising by a latch 17 mounted on the keyboard A and engaging a lip 16a of a bracket 16 on the link 13. If the assembled line falls within predetermined limits of length, as adjusted by setting a rider 30 with respect to a scale 7a on the slide 7, then after the slack in the line has been taken up by releasing the brake, the rider 30 will underlie a roller 31c carried by the movable contact 31b of a switch 31, so as to close the switch and energize a rotary solenoid 19, which acts on a lip 17a of the latch 17 to release the bracket 16 and allow the elevator to rise. Otherwise, in the case of automatic operation a slip clutch between the shaft 15 and the aforementioned lever prevents damage to the machine. The solenoids could be replaced by mechanical linkages.
