Title: Improvements in the recovery of pure dimethyl terephthalate
IPC: C07C69/82
Filed: 1957-05-01
Abstract: <PICT:0803849/III/1> Dimethyl terephthalate is purified by continuously distilling the crude ester under reduced pressure, condensing the vapour in a condenser and cooling it down to a temperature which lies above the melting point of the ester, withdrawing the ester in the liquid phase and solidifying it, and precipitating the dimethyl terephthalate entrained by the gases or vaporized liquid from the waste gases before they are allowed to escape through the suction apparatus onto the free atmosphere, by injecting water, withdrawing the resultant suspension and separating the ester.  In a preferred embodiment, crude dimethyl terephthalate is heated in a vessel 1 by internal or external steam heating coils 2.  The vaporous dimethyl terephthalate passes through a column 4 and a dephlegmator 5 and into a condenser 7 in which the ester is condensed to a temperature such as 145-155 DEG  C. which is above the melting-point of the ester.  The liquid ester without further cooling passes into a separating vessel 8 and a down pipe 9.  The ester is crystallized on rollers 10 and passes through a pipe 11 to storage. The waste gas leaves the condenser 7 at a temperature above the melting-point of the ester and passes through a heated tube 12 into an injection condenser 13 and then through a suction apparatus attached to the pipe 14.  By injecting water at a temperature of 0 DEG  to 25 DEG  C. through pipe 15 into the condenser 13 the dimethyl terephthalate entrained by the waste gases is precipitated in solid form and flows down through pipe 16 as a milky aqueous suspension. After contrifuging and drying this fraction is extremely pure.ALSO:Dimethyl terephthalate is purified by continuously distilling the crude ester under reduced pressure, condensing the vapour in a condenser and cooling it down to a temperature which lies above the melting point of the ester, withdrawing the ester in the liquid phase and solidifying it, and precipitating the dimethyl terephthalate entrained by the gases or vaporized liquid from the waste gases before they are allowed to escape through the suction apparatus into the free atmosphere, by injecting water, withdrawing the resultant suspension and separating the ester.

Title: Improvements in or relating to multiplex carrier signalling systems
IPC: H04J1/04
Filed: 1946-05-08
Abstract: 632,647. Multiple radio signalling. STANDARD TELEPHONES & CABLES, Ltd., and HINTON, L. T. May 8, 1946, No. 13903. Drawings to Specification. [Class 40 (v)] In a multi-chamiel single-sideband radio communication system, in which the separate channels are translated into the transmitted spectrum by at least two successive modulations, at least one of which is a group modulation, in any process of group modulation, the group of modulating frequencies occupies a band not greater than an octave wide. Similar considerations apply at the receiver. In one example three voice frequency channels of band width 200 to 3000 c/s. are shifted to form the bands 11,200 to 14,000 c/s., 15,200 to 18,000 c/s. and 19,200 to 22,000 c/s. respectively by single sideband modulation of appropriate sub-carriers. The shifted bands together with a pilot frequency of 14,500 c/s. modulate a 20 mc/s. carrier, and the upper or lower sideband may be selected for transmission. The first local oscillator at the receiver has a frequency such that the I.F. output consists of the group of channels occupying a frequency band not greater than an octave wide, the individual bands then being separated by filters and shifted to their original voice frequency bands. The first local oscillator frequency is controlled by a voltage derived from the pilot channel and a locally provided stable reference oscillator. Specification 346,422 is referred to.

Abstract: 883,170. Purifying radio-isotopes. ZENTRALINSTITUT FUR KERNPHYSIK. April 23. 1959 [Sept. 4, 1958] No. 13945/59. Class 39(4) Radioactive iodine 132 is separated from a fission fraction containing tellurium 132 in the form of a solution of a tellurite by passing the solution through a chromatographic column packed with a cationic material charged with reducing ions, and then passing an eluant through the column to remove iodine 132 which results from the decay of tellurium 132. The column may contain a resinous cationic material which has been charged with stannous ions. A coating of tellurium forms on the resin grains and iodine 132 is removed by eluting with distilled water. Reference is made to prior art processes which include (1) distilling iodine from a melt of lithium chloride and potassium chloride containing tellurium; (2) treating tellurium with a permanganate solution to obtain the iodine as an iodate which is reduced to iodine; (3) filtering a suspension of tellurium dioxide in a solution of sodium acetate.
