Ltd 21 July 1970 [23 July 1969 (2) 28 July 1969 (4)] 35221/70 Heading H4F [Also in Division H1] A cathode-ray tube adapted for pick-up or recording in a facsimile transmission system comprises a luminescent strip screen 19 disposed in a slit in the end wall of the envelope 11 adjacent a thin window 18. In the recording mode the modulated light from the screen exposes photo-sensitive material disposed adjacent the window. In the pick-up mode the copy 22 is illuminated by unmodulated light from the screen, and light 23 reflected from the copy is reflected at the surface 24 of the envelope 11 and passes sideways out of the envelope to a photo-sensitive detector. The surface 24 may be coated with aluminium, gold or nickel, and the phosphor 19 may be provided with a metal backing 25. There may be a gap 26 between the window 18 and the envelope 11 so that rays 23 at greater than the critical angle do not pass to the output; this increases the signal/ noise ratio. The window 18 may be joined to the envelope 11. The surface 24 may be parabolic or elliptical (Fig. 5, not shown). The detector may comprise photo-conductive material (27, Fig. 6a, not shown) coated directly or through an intermediate layer or to the envelope. Alternatively the light emerging from the sides of the envelope may be focused by a convex lens or a Fresnel lens or to one or more photo-multipliers (Figs. 6b-6d, not shown). Operating circuit, Fig. 7.-In the pick-up mode, signals from the detectors 29 on each side of the window assembly 13 are fed through respective amplifiers to a comparator 39 which controls the deflection coils 16 so that the beam is maintained in the centre of the slit target.

Title: Process for the separation of iron, aluminium and titanium values from materials containing them
IPC: C01F7/743
Filed: 1956-11-30
Abstract: Iron, titanium and aluminium values are recovered from materials comprising their oxides, together with silica such as ilmenite in admixture with silica and alumina, high iron bauxite ores, and the red mud residues resulting from the alkaline extraction of bauxite ores, by calcining the raw charge material, preferably between 800 DEG C. and 1350 DEG C. and smelting the material with a carbonaceous reducing agent in an electric furnace, the ratio of alumina to silica being 1 to 3 moles of alumina to 3 to 2 moles of silica, thus obtaining molten iron, and a slag containing substantially all the titania, alumina, and silica. The smelting is preferably carried out in an electric arc furnace in which the electrode tips are adjusted so as to be from 1/2 inch above the top of the slag bath to 3 inches below the top of the slag bath.  This prevents segregation of the components of the charge.  Further it is advantageous to arrange the feed of solid down the sides of the furnace, so that the molten slag does not come into contact with the furnace walls. The metallic iron is separated, and the slag is digested with aqueous sulphuric acid, preferably of at least 60% concentration. A solution of aluminium and titanium sulphates, and an insoluble residue of silica is obtained. The residue is removed and the solution is first treated to obtain aluminium sulphate, which may be calcined to the oxide, and then for the recovery of titania. If there is any unreduced iron oxide in the slag, or if the titanium is present as the dioxide, which with sulphuric acid gives the oxysulphate, metallic aluminium is added to the solution in sulphuric acid to reduce the iron oxide to iron, which is precipitated, and to convert the oxysulphate to the sulphate.  In a modification, the slag is digested with dilute sulphuric acid to form a solution of aluminium sulphate, and the residue of silica and titania is then treated with a more concentrated sulphuric acid to give a solution of titanium sulphate. The solutions are then separated, treated to recover aluminium sulphate which may be converted to alumina by calcining, preferably by heating to about 690 DEG C. and finishing at 1000-1100 DEG C., and titania by hydrolysis of the titanium sulphate solution.
