Abstract: 1,236,243. Purification of solvents used in olefine-polymerization processes. FIRESTONE TIRE & RUBBER CO. 24 Sept., 1968 [26 Sept., 1967], No. 45409/68. Heading B1B. Contaminated solvent (e.g. hexane) derived from two or more stages in the recovery of a polymer or copolymer of 1, 3-butadiene and/or isoprene, is purified by introducing the mixture of steam, vaporized solvent and heavy impurities (of higher boiling point than the solvent) from a polymer crumbing operation, through line 11 into the lower section of a fractionating column 10, and introducing into the column through line 12, at a higher level, liquid solvent contaminated with heavy impurities from one or more polymer finishing operations. The steamvaporizes the liquid solvent in the column so that relatively pure solvent vapour, and some steam, leaves the top of the column, while a mixture of solvent, heavy impurities and steam-condensate is removed from the bottom of the column. If necessary, additional steam is supplied to the column from source 26. The overhead vapour flows to condenser 15, and the solvent condensate is decanted from water in tank 17 from which part of the solvent is pumped back to the column through line 24 which passes through heater 25. The remainder of the solvent is withdrawn through line 23, and is freed from light impurities in a further fractionating column. The mixture removed from the bottom of column 10 is separated into water and solvent in tank 29, and the solvent is passed through line 32 into a further column where the heavy impurities are eliminated. Part of the solvent from tank 29 may be returned to column 10 through line 33.

Abstract: 1,218,710. Moulding-machines. SPO Inc. 15 Sept., 1969 [19 Sept., 1968], No. 45416/69. Heading B3F. A device for compacting moulding sand comprises a squeeze head 20 having cavities 27 within which hydraulically extensible rods 43 having peen feet 67 are arranged, each of the rods 43 being surrounded in its cavity by a flexible cylindrical sleeve 30 providing an interference fit with the rod, said sleeve being expandable within the cavity by exerting hydraulic pressure on it so as to be releasable from said interference fit to permit axial displacement of the rod 43. The fluid is supplied to annular grooves 54 and an axial groove 55 on the inner surface of each cylinder 30 from a source 63. The rods 43 are then displaceable by fluid supplied from a source 51, the downward movement of the rods 43 being limited by snap rings 47. In use, the rods 43 and feet 67 are set at predetermined heights by means of gauge pins 80, Fig. 1, and are then locked in position by the cylinders 30. The whole squeeze head 20 is then moved downwards to compact the sand in a flask (75). An alternative method of setting the feet 67 at the required height involves applying to the unlocked rods an hydraulic pressure corresponding to the unlocked rods an hydraulic pressure corresponding to the final sand pressure required and lowering the head 20 slowly to compress the sand. The rods 43 are thus forced back to desired heights and are then locked in position.
