[Class 43] [Also in Group XI] A process for forming a glossy, scratch-free surface on a non-combustible crystalline precious or semiprecious stone having a rough surface, e.g. corundum or spinel, comprises heating a thin layer of the stone to a temperature above 1900‹ C until complete coalescence of the fused crystal facets occurs, by applying to it a soft, high temperature gas flame formed by the intersection of a plurality of flame jets, while retaining the interior of said stone in a solid condition, and then resolidifying said layer. A partially glossy, wavy surface may be formed by removing the stone from the flame as soon as the sharp, projecting crystal facets of the stone in the as-grown condition have been fused superficially and rounded over, but before complete coalescence and the attainment of a fully glossed even surface occurs. A fully glossed wavy surface may be formed by heating the surface of the stone completely to fusion, while maintaining the flame source close to the surface so that the dynamic action of the gases in the flame ripples the molten material, which is then allowed to solidify. Unicrystalline rods of corundum or spinal having sub-surface bubbles may be ground until the bubbles appear as cavities on the surface, which may then be glossed as above so that the sharp edges of the cavities are rounded off.

Title: An improved method of, and apparatus for grinding spherical surfaces
Inventor: TURNER JOHN R
IPC: B24B13/01
Filed: 1950-04-20
Abstract: 671,766. Grinding lenses and the like. KODAK, Ltd. April 20, 1950 [April 20, 1949], No. 9739/50. Class 60. A spherical surface is produced on workpieces 10 by rotating them about an axis passing through the centre of the surface while they are in contact with a grinding wheel having an outer ring 18 of coarse abrasive, an inner ring 19 of fine abrasive and a diameter large enough fully to embrace the surface to be ground, relative feed between the work and wheel being effected along the axis of the latter which is inclined to the axis of rotation of the work. In Fig. 1, the workpieces 10 are shown as lens blanks mounted in a blocking tool 12 which rotates about the axis of a spindle 15 while the tool is rotated about the axis of a spindle 17. The operative faces of the rings 18, 19 may have radii corresponding to those of the work at the start and finish of the grinding operation respectively. When the tool is first brought into contact with the work, the outer periphery of the coarse ring 18 is operative, but as grinding proceeds and the radius of curvature of the work decreases, the fine grinding ring 19 becomes operative. If the change in curvature of the surface to be generated is insufficient to permit the changeover from one ring to the other it is necessary to retract the coarse grinding ring as the grinding proceeds. This is effected by the apparatus shown in Fig. 8 in which the fine grinding ring 19 has a spindle 44 slidably keyed to a sleeve 48 carrying the coarse grinding ring 18. A compression spring 51 biasses the spindle and the sleeve to the relative position shown. The sleeve 45 is rotated by a belt 49 and forms a rotating and sliding fit with a cylinder 46 connected by a valve 60 with a compressed air supply. With the valve in the position shown, air enters a chamber 55 from which it passes through ports 56 to the top of the spindle 44 so that the latter, and with it the sleeve 45, is forced downwardly to bring the ring 18 into contact with the work. The end of the rough-grinding operation is determined by the setting of an adjustable stop nut 61. which strikes a flange 62 of the cylinder 46 to terminate the down feed of the sleeve 45 so that the spindle 44 descends alone until the spring 51 is fully compressed. At this point, the fine grinding operation is complete and the valve 60 is rotated to allow the air to exhaust from the top of the spindle 44 and to admit air to a chamber 65 to lift the sleeve 45 ready for the next operation. The tool shown in Fig. 1 may be adapted for treating concave surfaces and may be fed to the work by compressed air acting on a piston secured to the tool spindle. The ring of coarse abrasive may be made narrower in width than the ring of fine abrasive. The abrasive used may be diamond dust.

Abstract: 501,233. Distilling alaminium ; materials for making coke; aluminium, sulphide; alloys. GARDNER, D. March 31, 1938, No. 9878. [Class 82 (i)] [Also in Groups III and XII] Aluminium is obtained by first forming aluminium sulphide either by heating oxide or hydroxide compounds such as alumina or bauxite with low temperature coke in the vapour of sulphur or carbon bisulphide to over 1500‹ C., or by heating aluminium sulphate with low temperature coke to 900-1200‹ C., the aluminium sulphide so formed being then reduced by heating it with iron, ferro-titanium, ferro-silicon, ferro-chromium, or copper to a temperature above the distillation point of aluminium in a reducing or inert atmosphere such as hydrogen or argon, preferably with the addition of some carbon and a flux such as aluminium fluoride.. The metallic reducing agent is preferably present in large excess. The aluminium vapours are cooled in a suitable condenser and may be directly combined with a molten charge of a metal such as magnesium or beryllium or their alloys for the production of aluminium alloys. The reactions may take place in succession to render the process continuous. The low temperature coke may be obtained by heating material such as anthracite duff or brown coal to 400-500‹ C. for 1-3 hours.
