A work-table 50, Fig. 1 (not shown), is supported on a base 10, and carries a work-piece 52, and air is first supplied to lift the table to allow adjustment of the latter relative to the base, and is then exhausted to lock the table on the base. A chamber 16 is divided by a diaphragm 42 connected to a plunger 40, which is urged upwardly to engage a template 46 by a spring 38. The template is fixed to the table and has apertures 41, 43, 45 corresponding to the holes to be drilled in the work-piece, and forms a chamber 18. In operation, two three-way valves 30, 26 connected together and actuated by a foot pedal 36 supply compressed air from a source 20 to lines 12 and 14, thus flexing diaphragm 42 to retract plunger 40, and also floating table 50. The table is adjusted, and the valves are moved so that the chamber 16 is exhausted, thus allowing plunger to be moved upwardly to engage the template, and register with the required aperture. The valves are further moved, chamber 16 is still connected to atmosphere, and chamber 18 is now connected to a source of vacuum 34, thus locking table 50 on to the base. In a modification, Fig. 4 (not shown), a rotary table 110 is normally urged into engagement with base 100 by a nut 124, and spring S, but is floated as in Fig. 1 (not shown). In a further modification, Figs. 5, 6 (not shown), the template 156 has grooves 170, 172 which form the chamber to which the air is supplied for floating table 152. In a still further modification, Figs. 7, 8 (not shown), table 210 is floated and clamped as before but is restrained to move in two directions at right angles by a pantograph 200 which co-operates with a drawing or similar sheet 216, and has a microscope 222 secured thereto. The pantograph may be replaced by a rigid bar 302, Fig. 10 (not shown), secured to base 300, on which slides a cross member 304. A rail 306 is carried by member 304, and table 308 is adjustable along this rail. A microscope may be used for setting table 308, or alternatively screens 312, 322 may be used.

Filed: 1958-12-31
Abstract: A cured aqueous mixture of colloidally dispersed hydrated titanium oxide, a source of fluoride ions and hydrochloric, hydrobromic hydriodic or nitric acid may be employed as seed material in hydrolysing titanium sulphate solutions to give a rutile-forming precipitate.  The mixture may be prepared by peptising washed and purified orthotitanic acid with the other components, heating the mixture directly or indirectly with steam to form the dispersed seed and curing the mixture by allowing to stand at room temperature or by heating at or near the boiling point.  In the examples the orthotitanic acid is prepared by precipitation by adding titanium sulphate solution prepared from metatitanic acid to a sodium carbonate solution, filtering and washing.  The invention permits the formation of stable seed material having concentrations up to 180 g./l. TiO2. Hydrochloric acid if used may be present as 20-50% wt. of the TiO2 and corresponding proportions of the alternative acids may be used: hydrofluoric acid if used as the fluoride source may comprise 0.1-5% wt. of the TiO2.  Other sources of fluoride ions are alkali metal and alkaline earth metal fluorides.  In hydrolysing a sulphate liquor 0.5-1.5% of the seed material by weight of hydrolysable TiO2 in said liquor may be used, and the seed material may be employed as such or after coagulation e.g. by ammonium hydroxide, and washing to remove halides.  In the examples 0.4% Na2CO3, 0.075% Li2CO3 and 0.2% NH4H2PO4 were added to the washed filter cake prior to calcination.
