Title: Improvements in or relating to the production of spherical bodies
Inventor: BRANY JAROSLAV
IPC: B24B11/06
Filed: 1968-06-07
Abstract: 1,223,618. Grinding balls. VYZKUMNY USTAV STROJIRENSKE TECHNOLOGIE A EKONOMIKY. 7 June, 1968, No. 27178/68. Heading B3D. A method of grinding or lapping a spherical body comprises subjecting the body to a rolling action between working surfaces of which at least one constitutes simultaneously a control surface, positively displacing the rolling prints between the spherical body and the working surfaces in relation to an axis of the spherical body perpendicular to the working surfaces to produce a system of meridians intersecting one another in poles, and interrupting the positive  displacement of the rolling points by a dwell after the required portion of the meridian system has been produced to effect a phase shift by the dwell and to determine the angular spacing of a previously formed pole from the pole formed after the dwell. In apparatus for carrying out the method, a working disc 4, which may be fixed or rotatable, is mounted in a support 1 and faces a second working disc 6 rotatably driven by a belt 12 and carried in a support 2. The spherical bodies are fed to the discs from a belt-driven drum-type magazine 15 having a supply tube 21 and discharge tube 22. A lever 24 can be released from a claw 23 to permit tilting of the magazine for emptying. Grinding or lapping emulsion can be fed to the discs through a funnel 25. The discs may be arranged in a vertical or horizontal position. In a known machine which is described, the bodies 30, Fig. 2, are engaged by grooves 31, 32 in discs 4, 6 and have rolling points 33, 34 where there is no movement relative to the contacting parts of the groove and hence no abrasion at those points. In the apparatus according to the invention, the groove 32, Figs. 4 and 7, in the disc 4 consists of a number of wavy formations 44 followed by dwells 45. The wavy formation has the effect of varying the axis of rotation 37 of the body so that a system of meridians 60, 61, Fig. 9, is formed at a pole 51, each meridian consisting of a half-circle described around the circumference of the body. The dwells following the wavy formations cause the bodies to be displaced so that following systems of meridians are formed at other poles 52, 53, whereby the bodies are covered by a uniform system of meridians. The waves may be sinusoidal or zigzag and the number of waves may differ in consecutive sequences. The groove may contact the body along a continuous arc or at spaced points.

Abstract: 724,198. Electrolytic preparation of titanium. IMPERIAL CHEMICAL INDUSTRIES, Ltd. Nov. 3, 1952 [Nov. 23, 1951], No. 27519/51. Class 41. A process for the manufacture of titanium comprises electrolysing a titanium compound dissolved or suspended in a fused salt in the presence of molten zinc, cadmium or lead or mixtures of two or all of these metals in which the titanium is soluble at the temperature of electrolysis, withdrawing the alloy of titanium and the molten metal or metals so formed during the electrolysis and recovering the titanium therefrom. The titanium compound may be a titanium halide, or an alkali or alkaline earth metal titanate, or pure titanium dioxide, or a natural rutile with a titanium oxide content of over 98 per cent. The fused salt may be an alkaline earth metal halide, such as calcium chloride, or a mixture of these halides, or an alkali metal fluotitanate. The preferred melt is one in which the titanium compound is soluble. The molten metal is preferably made the cathode. Electrolysis is continued until the concentration of titanium in the alloy has a value of 2-3 per cent, when the alloy is tapped off. The titanium may be recovered by distilling in vacuo to leave a titanium residue, or the alloy may be cooled to precipitate titanium as metal or as a complex, which is separated by filtration and may then be distilled in vacuo to recover the titanium. Specification 697,487, [Group II], is referred to.
