Abstract: .266,825. Cooper, C., Henshaw, D. M., and Holmes & Co., Ltd. W. C. Dec. 5, 1925. Drying gases.-Fuel gases are dried, immediately prior to their admission into furnaces &c., by intimate contact with hygroscopic or waterabsorbing liquids, such as a solution of calciumchloride, which may be regenerated either intermittently or continuously, the temperature of the gases remaining substantially constant. The gases pass through a drying tower 1 from an inlet '2 to an outlet 3 in the opposite direction to that of the absorbent liquid which is distributed by a perforated pipe 5 which communicates with a hopper 4 containing a vessel which overturns on becoming full. The spent liquid is withdrawn from the tower by a pump 7 and discharged into a perforated tray 10 which distributes the liquid over the steam-heated regenerator pipes 11. The 'liquid thence flows into a tank 14 from which it is withdrawn by a pump 16 and forced through a cooling-coil 17 and a pipe 18 to the tilting vessel in the hopper 4. The drying tower is packed with a suitable material or provided with perforated trays. Specification 162,116, [Class 55 (ii), Gas manufacture &c.], and 248,841 are referred to.

Abstract: 1440184 Refractory structure IMPERIAL CHEMICAL INDUSTRIES Ltd 13 June 1973 [3 July 1972] 31043/72 Heading C1A [Also in Divisions B5 and F2] A refractory structure comprises a paper, cloth, sheet, board, blanket or felt of refractory metal oxide fibres bonded with a refractory binding agent wherein the refractory metal oxide fibres are formed by fibrizing a composition having a viscosity greater than 1 poise comprising an aqueous solution or sol of a metal compound which can form a refractory oxide and a minor proportion of a water-soluble organic polymer, drying the fibre formed and heating to decompose the metal compound to oxide and to decompose the polymer. The fibres are impregnated with a liquid composition, e.g. colloidal or dissolved inorganic oxy-compound, convertible to give a refractory bonding agent and can be formed into the desired shape before or after impregnation but before bonding by heating to 400-1500 C. It is preferred to use alumina or zirconia fibres made from an oxychloride, basic acetate, basic formate or nitrate of aluminium and/or zirconium and the preferred water-soluble organic polymers include polyethylene oxide, polyvinyl alcohol, and polyvinyl pyrrolidone. The compositions convertible to form a refractory bonding agent are preferably liquids containing compounds which can form a refractory oxide by heating, e.g. hydrated oxide sols of alumina, silica, titania, zirconia, oxychloride, basic acetates or basic formates of aluminium and/or zirconium; aluminosilicates; and alkali metal silicates, alkyl silicates, alkyl titanates. The refractory structure prepared may take many forms, e.g. sheets may be built up into thick wads by laminating, ridged or embossed sheets may be used in conjunction with plain sheets to provide an assembly with passages which can be formed into a spiral roll or tube.

A landing approach aid for an aircraft comprises a head-up display in which markers are provided to be lined up by the pilot with points on the runway. One marker may be a horizontal line depressed below the horizon by an angle # 1  (as viewed by the pilot, see Fig. 1) which the pilot may line up with the touchdown point, and means are provided for varying # 1  as an approach is made so that the main landing wheels of the aircraft remain on a required glide path of angle γ. (With a small aircraft # 1  would be constant and equal to γ). A second marker is depressed by an angle # 2  below the horizon and is lined up by the pilot with the runway threshold. The deviation for a large aircarft of # 1  and # 2  from γ with decreasing altitude is illustrated in Fig. 2 (not shown) for a glide path angle of 3 degrees. It may be shown (referring to Fig. 1) that, for a glide path angle of 3 degrees, and that #h = S 3 #, (where # is the attitude angle of the aircraft, h is the altitude of the main landing wheels and Ah is the vertical distance between the pilot's eyes and the main landing wheels for the prescribed attitude angle #) so that, knowing S 2  and S 3 , # 1  and # 2  can be calculated from a knowledge of the attitude angle and the altitude of the aircraft. Means for measuring these quantities are provided and these feed circuitry (Fig. 3, not shown) which provides outputs representing (# 1 +#) and (# 2  + #), i.e. the angles by which the markers in the head-up display must be depressed to afford depressions of # 1  and # 2  below the horizon. These outputs cause production of the required marker symbols on a cathode-ray tube which are then seen by the pilot in head-up display.
