Title: Improvements in and relating to the manufacture of oxides
Inventor: WOODHALL WILLIAM
IPC: C01G23/07
Filed: 1960-12-16
Abstract: In the production of oxides of aluminium, titanium, zirconium, iron and silicon by vapour phase oxidation of the chloride, the reactants are fed into an elongated reactor in such a manner that a conical diverging gas stream is formed which does not reach the reactor walls.  Heat is supplied by incorporating with the reactants a mixture of an oxidizing gas and a fuel gas which is combusted out of contact with the chloride.  The reactor walls are cooled by a lamina stream of cooled recycled chlorine product gas. The <PICT:1010061/C1/1> build-up of oxide on the chloride inlet nozzle is avoided by projecting the chloride at such a speed, generally greater than 100 ft./sec. that reaction temperature is not attained until a point downstream of the nozzle.  The oxidizing gas may be incorporated with the chloride or with the fuel gas prior to mixing. The gas inlet nozzle preferably comprises two coaxial openings, the chloride is fed in through the outer of the two openings and the oxidizing gas and fuel gas together through the inner opening. Preferably the oxidizing gas that reacts with the chloride and the oxidizing gas that reacts with the fuel gas are the same and are preferably oxygen, the fuel gas being carbon monoxide.  According to the preferred embodiment, air and oxygen are introduced through pipe 7, carbon monoxide is introduced through pipe 8 and the mixture is sparked at point 9.  Titanium tetrachloride is introduced through pipe 20 and bores 19 into the gas stream.  Initially cold air and thereafter cooled recycled chlorine is introduced through aperture 17 and flows through space 16 along the walls of the reaction chamber. For the production of titanium dioxide with a rutile structure, aluminium chloride is injected into the reaction zone or may be incorporated with the titanium tetrachloride prior to introduction into the reaction zone.  Alternatively finely divided aluminium metal may be incorporated with the fuel gas prior to combustion with the oxidizing gas.

Title: Improvements relating to gas testing
IPC: G01N33/00
Filed: 1961-12-05
Abstract: 966,343. Gas analysis. BRITISH PETROLEUM CO. Ltd., N. EVANS, and J. R. WILES. Nov. 9, 1962 [Dec. 5, 1961], No. 43485/61. Headings G1B and G1N. A method for determining the solid carbon content of gases comprises continually sampling the gas e.g. by use of a line 1 from a flue, splitting the sample into two streams i.e. in branches 3, 4, treating one stream to remove solid particles e.g. using a glass wool filter 5, subjecting each stream to combustion conditions e.g. in an electric furnace 6 at above 850C., and comparing the thermal conductivities of the streams e.g. using thermistors 12, 13 connected in a bridge circuit 17, or the hot wire technique. The flue gas in the line 1 may, if necessary be mixed with air from a line 2 to ensure complete combustion. The gas in the branch 4 passes direct to the furnace 6 when its solid carbon content is burnt to carbon dioxides and it then passes to a diffuser 10 identical to the filter 5 to correct for the effect of the filter in the branch 3. The filter 5 removes solid carbon from the gas in the branch 3 so that the differences in carbon dioxide content of the gas streams leaving the furnace 6 is a measure of the solid carbon content of the sample flue gas. The gas streams pass through respective control valves 8, 11 to a thermal conductivity detector 9 containing the thermistors 12, 13. A constant gas flow rate is ensured by the provision of an orifice 15 in a manifold 14 in which the gas streams merge, and a vacuum pump 16 is used to draw gas through the apparatus. The thermistors are arranged to each give an output proportional to the thermal conductivity of one of the gas streams, the difference between their outputs being detected by the bridge circuit 17 and fed to a recorder 18 which is calibrated to read in grams of carbon per litre of flue gas.

Abstract: 1,069,494. Yarn dyeing apparatus. KILSUNDS A. B. Nov. 6, 1963 [Nov. 14, 1962], No. 43792/63. Heading D1L. Yarn dyeing apparatus comprises a number of perforated tubes 3 projecting upwardly from a distribution chamber 1 fitted in a dye liquid tank (not shown) and connected to a circulation pump for circulation of the dye liquid. A plate 5 supports a number of cheese wound yarn packages 6 situated around each tube 3. Each cheese comprises a sleeve 8 having holes 7 therein, the inner diameter of the sleeve being larger than the outer diameter of tube 3 so that there is a space 10 therebetewen. The space 10 is sealingly closed at the lower end by an annular plate 11 and between the cheeses, spacer elements 13 are fitted which seal against the tube 3 and the sleeves 8. The arrangement is such that the openings 7 in sleeves 8 and the openings 2 in tube 3 have such dimensions that the sum of the areas of the openings 7 in all the sleeves 8 on a tube 3 is larger than the sum of the areas of all the openings 2 in the tube 3 and the last mentioned sum is smaller than the internal crosssectional area of the tube. By virtue of this the same pressure may be maintained in the separate spaces between the sleeves 8 and the tube 3 so that all the yarn packages 6 will be subjected to substantially the same rate of through-flow of the dye liquid.
