Title: A hydraulic cylinder adapted to self purge gases accumulated therein
IPC: F15B21/044
Filed: 1967-07-18
Abstract: 1,135,364. Hydraulic presses. GRAND VALLEY MACHINE & TOOL CO. 18 July, 1967 [15 May, 1967], No. 33001/67. Heading B5F. [Also in Divisions F1 and F2] Air 27 which collects beneath the piston 13 of an hydraulic cylinder 12 for supporting part of the die of a press, Fig. 6 (not shown), is pumped during reciprocation of the piston 13 into an hydraulic line 14 connected to a sump 26 formed at the end of the cylinder and into which the air passes from the bore 24 of a flanged tubular purging member 19 fixed to the underside of the piston 13. When the piston is forced into the cylinder by the movable part of the press, air beneath the piston flows through radial openings 23 in the flange 20 of the member 19 into the axial bore 24 and then into the sump 26 for passage through the line 14 for ultimate removal either by separation at the air-liquid interface of a pressurized tank, or by collection of the air at a selected region from which it may be bled. The return stroke is performed, when the press part is returned, by supplying liquid through the line 14 under the action of the air loading in the tank. The member 19 has further radial openings 25 through the tubular portion 21 and may be formed in two parts, Fig. 8 (not shown).

Title: Organic titanium complex and method of making same
IPC: C07C51/41
Filed: 1956-10-30
Abstract: A substantially pure aqueous solution of titanyl sulphate is prepared by reacting a hydroxide, oxide or carbonate of calcium, strontium or barium with an aqueous solution of a commercial grade titanyl sulphate at a temperature not above 55 DEG  C. to remove the extraneous metal values therefrom as insoluble sulphates, oxides or oxy-sulphates.  The purified titanyl sulphate solution may contain 100-160 grams TiO2 per litre and have a H2SO4/TiO2 mol. ratio of 1.1 to 1.3.ALSO:A water-soluble acidic titanium lactate complex is prepared by reacting a lactate of calcium, strontium or barium with a substantially pure aqueous solution of titanyl sulphate.  The preferred products are the titanium monolactate complex wherein the ratio of Ti to lactic acid is 1:1, and the titanium dilactate complex wherein the ratio of Ti to lactic acid is 1:2.  Salts may be prepared by altering the pH of the solution which is normally 1 to 2 by adding ammonia, the carbonates of alkali metals, or the hydroxides, oxides and carbonates of calcium, strontium, barium or magnesium.  In the preferred process, a purified aqueous solution of titanyl sulphate is prepared by reacting calcium, strontium or barium hydroxide, carbonate or oxide with an aqueous solution of commercial grade titanyl sulphate at a temperature not above 55 DEG  C. to remove the extraneous metal values as sulphates, oxides or oxy-sulphates, reacting calcium, strontium or barium lactate with the purified solution so that 1 to 2 mols. of lactic acid is introduced per gram atom of titanium, together with sufficient hydroxide, oxide or carbonate of calcium, strontium or barium to precipitate any excess sulphate ions, filtering the mixture to obtain an acidic titanium lactate complex having a pH of 1 to 2 and then altering the pH by adding suitable alkalies as mentioned above.  The alkaline earth metal lactate reacted with the titanyl sulphate may be added as such or prepared in situ from lactic acid and an hydroxide, oxide or carbonate of calcium, strontium or barium.  The products may be used as mordants in dyeing processes for treating fabrics and leather, and as a cross-linking agent for cellulosics and polyvinyl alcohols. Examples describe the preparation of the acidic titanium monolactate and dilactate complexes and the preparation of salts therefrom.
