Title: Improvements relating to the separation of component substances from mixtures thereof
IPC: B01D53/14
Filed: 1947-12-24
Abstract: Phenol is removed from admixture with water by dividing up the mixture into separate streams and flowing them counter-current to carbon tetrachloride similarly divided so that the latter completely surrounds the former.  Benzol may similarly be absorbed by paraffin oil from admixture with coal gas.ALSO:<PICT:0657550/III/1> One or more constituents of a uniphase gaseous, liquid or solid mixture is separated off by dividing the mixture into a plurality of separate streams and flowing them countercurrent to an extraction liquid which is itself split into thin layers each completely surrounding a single stream of the mixture.  In operation, the gas mixture enters through pipe 37, passes through a filter 40, then pipes 31 out through branches 43 and leave the apparatus through pipe 44.  Meanwhile, extraction liquid enters capillary tubes 50 and passes down tubes 31 along the walls thereof thereby surrounding the uprising gas stream. The extraction liquid passes out of tubes 31 through filter 40 and leaves the apparatus through pipe 39.  In examples, chlorine is extracted from air by means of water, and phenol out of water by carbon tetrachloride.  The process may also be applied to air containing carbon dioxide using a solution of potassium carbonate, benzol absorbed from coal gas using paraffin oil, or a mixture of air and hydrochloric acid gas absorbed by water.  A heating or cooling jacket may surround the complete apparatus.

Title: Improvements in and relating to high frequency antennae
IPC: H01Q21/08
Filed: 1946-11-19
Abstract: 654,935. Aerials. BRITISH THOMSONHOUSTON CO., Ltd. Nov. 19, 1946, No. 34270. Convention date, Nov. 19, 1945. [Class 40 (vii)] An antenna including a half-wave folded dipole element curved in an arc and having means coupled to the elementfor supplying high-frequency energy thereto, is characterized by one or more conductors two ends of which are in spaced relation, one to each of the folded ends of the element to form a substantially closed loop, the effective length of the element and conductor(s) jointly being an integral, number of wavelengths of the carrier frequency used. The antenna is a development of that described in Specification 561,251, and is of particular value for vertically stacked arrays operating at high frequencies. In such arrays where the antennµ are arranged round a central supporting mast at one wavelength intervals the individual antenna of the prior Specification may not be of sufficient circumference to contain an adequately strong mast. A radiator according to the present invention may, for example, have an electrical length of a full wavelength. Such an antenna (Fig. 2) comprises a pair of closely spaced semi-circular conductors 19, 20, conductively connected at their ends by blocks 21 and 22 which are capacitively coupled respectively with blocks 23 and 24 joined by a further semicircular radiating member 25. Capacity variations between the pairs of blocks made by adjustment of screw mounted discs 27 and 28 enable the total electrical length of the aerial to be adjusted to a full wavelength at the operating frequency. The elements of the antenna may be supported at null points by metallic members 26 attached to the central mast 1 which may also be metallic. The antenna may be fed at 33 and 34 and where a number are fed in parallel as in a vertical stack quarter wave matching sections may be included between each antenna andthe common feeder. In a further embodiment, Fig. 3 (not shown), the circumference of the radiator is equivalent electrically to two wavelengths and is in four sections. Two energized oppositely disposed sections are similar to the sections 19, 20, 21, 22, of the previous embodiment but only occupy a quarter of the total circumference each. They are energized in parallel. The intervening sections are single segments (similar to 25) capacitively coupled to the energized portions at their ends. Mechanical support may be at the mid-point of each section as in the previous case. If a stacked array is arranged round a tapering supporting mast individual antennµ may vary between those of Specification 561,251, at the top to those of the present invention as the mast thickens lower down.

Filed: 1928-11-22
Abstract: 327,165. Imray, O. Y., (I. G. Farbenindustrie Akt.-Ges.). Nov. 22, 1928. Esters of polyvalent alcohols and carbohydrates. -Compounds of the nature of polyvalent alcohols and having at least one free hydroxyl group, for instance glycerine, or a carbohydrate, such as sugar, starch, cellulose or a cellulose derivative, for example, a low-esterified cellulose ester or a cellulose mono-ether, are esterified with the aid of a condensation product prepared from a carboxylic halide by splitting off and separating hydrogen halide, for example, by means of an anhydrous metal chloride, such as aluminium chloride, or a tertiary base, such as triethylamine or pyridine. The esterification may be carried out in presence of an indifferent diluent and a catalyst, such as sulphuric acid, an acid chloride or zinc chloride. The acid halide may be derived from any saturated or unsaturated fatty acid whether substituted or not or from a cyclic carboxylic acid. In examples, the separated compound obtained by shaking lauryl chloride with pyridine-bases and removing the precipitated pyridine hydrochloride by filtration, is allowed to react on cotton linters in the presence of chlorbenzene to give a cellulose laurate which is separated from the liquid and washed with methanol; the condensation product obtained by shaking acetyl chloride with pyridine and filtering off the precipitated pyridine hylrochloride, is heated with glycerine and chlorbenzene to give diacetin and triacetin, which can be purified and separated by distillation, preferably in a vacuum; naphthenic acid chloride is shaken with pyridine bases and after separation of the precipitated pyridine hydrochloride, the reaction product, dissolved in chlorbenzene, is heated with cotton to give a cellulose naphthenate, which is precipitated by ethanol and purified by extraction with methanol; phenyl-acetyl-chloride and pyridine are mixed in chlorbenzene, the pyridine hydrochloride formed is filtered off, cotton linters are added and the cellulose phenyl acetate precipitated and washed with methanol.
