Patent GB-872198-A (GB)
Title: Improvements in methods of producing chlorides of metals or metalloids
IPC: C01B35/06
Filed: 1958-08-25
Abstract: Chlorides of iron, aluminium, beryllium, titanium, zirconium and boron are prepared by chlorinating a sintered source material and a carbonaceous material, which prior to sintering have been ground to pass a 140 mesh sieve (United States Standard Sieve Series), the individual grains of source material having been sintered together such that they are also in good contact with the carbonaceous material.  The process is of particular use in producing titanium tetrachloride, in which case the source material may be rutile or ilmenite, or a slag produced by the partial reduction of ilmenite, for example sorel slag or sodium or boric acid containing slags.  The carbonaceous material may be charcoal, coke, for example petroleum or natural coke, coal, or carbon obtained from carbonaceous gases, for example carbon monoxide or hydrocarbons, at low temperatures.  The carbonaceous material is preferably employed in less than the stoichiometric amount, and the mixture of the source and carbonaceous materials may be extruded, briquetted, or pelleted.  A flux, for example boric acid, borax, fluorspar or phosphates, salts or oxides of alkali or alkaline earth metals, may be added to the material to be sintered, which sintering may be effected between 600 DEG C. and 1400 DEG C., preferably in a non-oxidising or inert atmosphere, for example, nitrogen, carbon monoxide or argon.  In the preparation of titanium tetrachloride, the source material may be treated to set up stresses therein, for example by rapid cooling.  A source of silica, for example clay, may be incorporated in the mixture prior to sintering to increase the strength of the chlorination residue, which residue may be leached with water and re-sintered for further chlorination, which may be effected in static or fluidised beds, preferably at 600-1100 DEG C.

Title: Improvements in or relating to method and apparatus for producing fibers
IPC: C03B37/065
Filed: 1951-11-27
Abstract: 705,621. Forming glass &c. fibres. OWENS-CORNING FIBERGLAS CORPORATION. Nov. 27, 1951 [Nov. 28, 1950], No. 27808/51. Class 56 Fibres are formed by flowing a stream of fibre-forming material toward a high velocity blast and establishing a zone of reduced pressure adjacent and at one side of the blast for directing the stream in a path having a component of movement opposing the movement of the blast so that the blast draws out the molten material into fibres. The burner 14 has a hollow body 15 of refractory material encased in metal 18, and gas is fed to the combustion chamber 16 through a pipe 20 and openings 23. Lateral trunnions 33 on the burner are journalled in a bracket 34 which is vertically adjustable on a member 37, and the burner is adjusted about the trunnions by means of screws 44 engaged in threaded openings in lugs 42 on the burner and engaging opposed surfaces of the member 34. The leg 38 of member 37 engages in groove 46 in a support 47, and the burner is adjusted longitudinally of the support by means of a screw 43 passing through a slot 45 in the leg 38. Secured to the forward end of the burner is a generally circular fitting 30, having walls 50, 51, 52 joined to form a chamber 53, the front wall 50 being projected upwardly in a rectangular shape 54 and serving to obstruct, interrupt, and modify the flow of air induced by the blast. The orifice 57 is of U-shape and the front wall 50 has a tongue-like portion 58 which slants towards the chamber 16. The surface of the fitting is cooled below the temperature at which molten material will adhere thereto by means of a cooling fluid, e.g. water, passed through a pipe 60 to its outlet adjacent the portion 63 of wall 58, circulated in the chamber which has a baffle 65, and removed through an outlet pipe. The upwardly extending walls 75, 76 of the orifice 57 converge, see Fig. 4, so that the gaseous blast is directed as at 78, this tending to negate the cooling effects of the induced air. The stream S of fibre forming material from a heated container flows vertically as far as the baffle 54 when the obstructed induced air creates a zone of reduced pressure causing the stream to continue downwardly adjacent but slightly spaced from the baffle, and then parallel to the sloping surface 58 into the orifice 57. The stream is tnen bent through an obtuse angle, Fig. 2, by the blast and attenuated into fibres, several streams may be attenuated concomitantly. Fig. 7 shows a steam or air blower comprising a chamber 83 fed with steam or air under pressure by a pipe 120, and fitted with a solid end plate 130 having an orifice 157 similar to orifice 57 and a projection 154.

Abstract: 471,641. Drying films. BRITISH CELLOPHANE, Ltd. Oct. 13, 1936, No. 27819. Convention date, Oct. 23, 1935. [Class 34 (i)] A method of, and apparatus for drying a wet non-fibrous self-supporting web or film subject to shrinkage comprises the steps of subjecting the web in a chamber and out of contact with any solid surface subsequently continuing the drying in contact with a solid surface. The invention is described in reference to sheets of regenerated cellulose but is applicable to other cellulosic and non- cellulosic materials of like character. A web 10 of non-fibrous cellulosic material suitably prepared is led through a bath 11 over rolls 12, thence between squeeze rollers 13 to a chamber 15. It is unsupported between rollers 13, 16, and is played upon by hot air or gas jets 17 arranged to extend forwardly as shown. The jets are arranged in multiple units, and are so spaced that there is sufficient passage for secondary air to reach the flames and for products of combustion to escape, assisted by suitable fans 32 &c. The web passes to heated drying rollers 40 and is collected on a winder 60. The web may be drawn through the apparatus by imparting rotation to some or all of the rolls, which may be regulated to allow for shrinkage. The water content of the web may originally be more than 300 per cent to be reduced to 10 per cent. Specification 471,640 is referred to.
