Title: Improvements relating to the purification of benzine
Inventor: BRADLEY DEREK
IPC: B01D9/00
Filed: 1958-08-18
Abstract: Benzene is benzole is purified by crystallising a major proportion of the benzene, separating the crystals, partly thawing by washing with an aqueous liquid and returning the thawed benzene after separation to the crystallisation.  The benzole may have been hydrofined or acid washed to remove thiophene and lower and higher boiling materials may have been separated by distillation. The crystallisation mother liquors may be distilled to separate a benzene fraction which is also returned to the crystallisation. The crystallisation is preferably effected by mixing with a cold, immiscible liquid, e.g. aqueous calcium chloride solution, and causing the mixture to flow with turbulence.  The Provisional Specification also refers to crystallising at least 75% of the benzene and thawing 10%-50% of the crystals and also to the separation of p-xylene from xylole.

Filed: 1953-09-28
Abstract: 736,475. Discharge apparatus. SOC. APPARECHI ELETTRICI E SCIENTIFICI. Sept. 28, 1953 [Sept. 27, 1952; Jan. 13, 1953], No. 26601/53. Class 39 (1). [Also in Group XXII] A getter container comprises a split tube or channel section member of toroidal or other closed shape, Fig. 10, having a longitudinal slit through which the getter vapour escapes. It is made by cutting the shape from metal sheet, and then pressing in a mould to form a U- or V- section, as in Fig. 13. The getter material L is pressed firmly in place, and then the channel is closed almost completely, leaving just a narrow slit F, Fig. 11, through which the getter evaporates. This evaporation may be given a directional effect by extending one wall of the con-, tainer as a wing A. Instead of being welded in position, such a getter may be simply supported by a thin wire. The metal sheet from which the getter is made may comprise several layers, bonded or folded together, Fig. 15 (not shown), for example a central layer of iron or steel, for strength; an outer layer of nickel, aluminium or other good conductor, to facilitate induction heating; and an inner layer which reacts advantageously with the getter material.

Title: Improvements relating to the stabilization of organopolysiloxanes
Filed: 1959-08-05
Abstract: The thermal and moisture stability of an organopolysiloxane liquid, resin or gum, which has been polymerized from a low to a higher molecular weight state with an alkali metal compound, is improved by contacting the siloxane with a quaternary compound of the formula Y4NX or Y4PX, where Y is a monovalent hydrocarbon or substituted hydrocarbon radical free from olefinic unsaturation and X is halogen, examples of which are given.  The siloxanes specified contain Si-bonded alkyl, alkenyl, cyanoalkyl or aryl radicals.  The quaternary compounds may be used in solid form or as solutions or suspensions.  The process is effected merely by mixing the siloxane and stabilizer at any temperature, e.g. from 20 DEG -150 DEG C. Examples describe the known polymerization and above stabilization of (1, 3) dimethylpolysiloxane and (2) g -cyanopropylmethylsiloxane-dimethyl-siloxane copolymer.
