Title: Improvements in or relating to crystallising hexitols
IPC: C07C31/26
Filed: 1952-03-20
Abstract: Traces of sparsely-soluble hexitols such as mannitol and dulcitol present in excess of the saturation quantities in a syrup of a readily-soluble hexitol, e.g. a sorbitol syrup, are removed by passing the syrup through a bed of crystals of the sparsely-soluble hexitol or hexitols.  The resulting syrup is clear and does not cloud on storage due to separation of the excess sparsely-soluble hexitol. In an example, an aqueous hexitol solution containing mannitol and sorbitol in the ratio 35 : 65 prepared by the catalytic reduction of invert sugar as described in U.S.A.  Specification 2,280,975 (example 3), is adjusted by evaporation to a water content of 23 per cent. The solution is cooled at 1 DEG  C. per hour to 20 DEG  C. precipitating the bulk of the mannitol, and filtered.  The mother liquor is concentrated to a water content of 15.5 per cent and then contains about 1 per cent mannitol in excess of saturation at 20 DEG C.  The solution, cooled to 20 DEG  C., is passed through a filter coated with mannitol crystals at the rate of 0.053 gal./sq. ft./hour. The filtrate remains clear for six months.  The unfiltered liquor deposits the excess mannitol over a period of three weeks.  The Specification also describes a prior method of removing the excess sparsely-soluble hexitols by diluting the syrup from which the bulk of such hexitols have been removed, with a solvent such as ethanol, cooling to a very low temperature and finally removing the solvent.ALSO:Traces of sparsely soluble hexitols such as mannitol and dulcitol present in excess of the saturation quantities in a syrup of a readily-soluble hexitol, e.g. a sorbitol syrup, are removed by passing the syrup through a bed of crystals of the sparsely soluble hexitol or hexitols.

Abstract: 512,686. Junction boxes. MYERS, W. L. March 11, 1938, No. 7570. [Class 38 (i)] One wall 5 of an electric conduit box is so shaped as to provide spaced recesses 6, which conform to the shape of lead-in conduits and co-operate with a clamp C to maintain the conduit rigidly in position. The pressed-metal clamping- strips are actuated by screws 15 near the upper and lower end wall of the box and have indentations 11 which partially encircle the conduit. The recesses 6 are spaced from the side walls 2, 4 to provide shoulders 9 which contact with the abutting ends 12 of the clamp to maintain it perpendicular to the longitudinal axis of the box. A flange 14 on the upper edge of the clamp turns inwards over the indentation to limit the movement of the covering of the inserted conduit. A flange 10 on the lower edge of the clamp contacts with the wall 1 of the box and is turned outwards from the indentation to close any gap left after the introduction of the conduit. The box is supported by a flat strip which slides in aligned apertures in the box and can be fixed to any plane surface, Fig. 1 (not shown).
