Title: Improvements in or relating to processes for eliminating chlorine from solutions containing zinc chloride and to improved solutions obtained thereby
IPC: C01G9/04
Filed: 1930-11-08
Abstract: A process for eliminating chlorine from solutions, as of zinc sulphate, containing zinc chloride comprises adding copper sulphate, and copper powder to convert the cupric chloride thus formed to insoluble cuprous chloride, which is removed.  The quantity of copper sulphate, which may be present at least in part in the solution treated, is preferably adjusted to be twice that theoretically required, and the copper powder, preferably obtained electrolytically at high current density, should be added in large excess, for example, ten times the theoretical quantity.  The cuprous chloride may be reconverted to finely divided copper, which may be employed in place of the electrolytic copper, by treatment with zinc balls, scrap, &c.  In an application of the process, zinc-containing alloys, as brass, admixed with coal and if required with zinciferous ores, are treated in a blast furnace.  The evolved fume is collected, and the residue admixed with a large quantity of alloy and blown.  Copper obtained from the converter passes to electrolytic refining operations.  The fumes from this and the previous operation, containing zinc, zinc oxide and sulphate, lead oxide, copper oxide, copper, tin, and silver are dissolved in sulphuric acid and treated for the removal of chlorine as above.  The solution, containing 0,3 per cent of chlorine or less, after further treatment, may be used for the preparation of lithopone.  The Specification as open to inspection under Sect. 91 (3) (a) comprises the removal of chlorine present in solution as chlorides generally.  This subject-matter, in its wide aspect, does not appear in the Specification as accepted. Reference has been directed by the Comptroller to Specifications 276,200 and 285,662, [both in Class 1 (iii), Oxides &c., Metallic].ALSO:In an application of a process for removal of chlorine from solutions containing zinc chloride, zinc-containing alloys, as brass, ad-mixed with coal and if desired with zinciferous ores, are treated in a blast furnace.

Title: Improvements in or relating to radar systems
Inventor: PLAISTOWE DONALD LEOPOLD
IPC: G01S7/282
Filed: 1946-11-14
Abstract: 640,353. Radiolocation. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Nov. 14, 1946, No. 33868. [Class 40 (vii)] A radar system employs an aerial scanning a full circle in azimuth and a cathode-ray tube displaying the range and bearing' of objects in a predetermined sector, means being provided, operable at will, for changing the sector. In Fig. 1 any one of the four quadrants ahead, port, starboard or astern may be selected for presentation on a type " B " display by a four - position switch QS which connects a relay RW to one of four brushes QCA, QCP, QCS, QCF spaced at 90 degrees around the periphery of contactor drum QC rotating synchronously with the aerial. A 90 degree " live " segment QC1 operates the relay for the duration of scan of the selected quadrant and contact RC of the relay connects an azi. muth time base to the display " X " plate amplifier V1, V2 whilst contacts RC2 bring the tube from a blacker-than-black to a black condition so that received signals applied to the control electrode may intensify the ray. The " Y " plates receive a normal range time base and the tube has sufficient afterglow to retain the " picture " traced during the selected quadrant during the scan of the other quadrants. The azimuth time base is generated by potentiometer AZ comprising a plurality of series-connected resistors AZ1 and a commutator AZ2 with segments connected to the junctions between resistors. A D.C. potential is maintained across the potentiometer by connections through slip-rings AZ5, AZ6 and the assembly is rotated at four times the aerial speed so that a potential rising in a series of small steps and then returning suddenly to zero is generated during each quadrant at the brush AZ7 bearing on the commutator. Condenser C1 smooths out the steps. To adjust the period during which relay RW operates to be greater or less than the time to scan a quadrant, " live " segment QC1 of contactor drum QC is tapered and the drum slides endwise under the brushes. The brushes themselves may also be adjusted in position. Expansion of the display azimuth scale is effected by adjustment of resistor R1 which controls the effective gain of amplifiers V1, V2 or by adjustment of resistor R which controls the potential applied across potentiometer AZ. The value of azimuth on which the expanded scale is centred may be adjusted by potentiometer P. A display in terms of true bearings may be obtained by carrying the four brushes QCA, QCP, QCS, QCF on a ring carrier positioned by gyro compass repeater and by similarly controlling brush AZ7. Figs. 3 and 4 (not shown), illustrate suitable graticules for use with the display.

Abstract: 1504776 Ethane and ethylene by hydrocracking DAVY POWERGAS Ltd 9 Aug 1976 [14 Aug 1975] 33928/75 Heading C5E A hydrocarbon feedstock containing at least one C 3  or higher hydrocarbon is subjected to vapour phase destructive hydrogenation at a feedstock to hydrogen ratio favouring the formation of ethane and ethylene rather than methane, the reaction being prevented from self-quenching by supplying to the hydrogenation zone hot combustion gases resulting from at least partial oxidation of a carbonaceous fuel with an oxygen-containing gas, and recovering from the hydrogenation zone a product stream containing ethane and ethylene. Ethane may be separated from the product stream and subjected to steam pyrolysis to form ethylene, the hydrogen formed being recycled to the hydrogenation zone. The destructive hydrogenation may be carried out at 650-750 C., and at 3-70 atmospheres absolute, optionally in the presence of a catalyst or inert material in a fluidized bed.

Abstract: Mixtures of polyvinyl chloride with a polymer or polymers derived from an ethylenically unsaturated monomer and having little or no compatibility with polyvinyl chloride are made by grafting the monomer of the polymer on to polyvinyl chloride and mixing the resultant graft polymer with the polymer which is incompatible with polyvinyl chloride.  The preparation is exemplified of polyvinylchloride/polyacrylonitrile mixtures by grafting acrylonitrile on to polyvinyl chloride, suitably by means of ionizing radiations, and mixing the resultant polymer with polyacrylonitrile. The graft polymerization may be carried out in successive steps as described in Specification 860,347.
