Patent GB-426764-A (GB)
Title: Improved process for the removal of solvents from oils and other organic liquids
IPC: C10G21/28
Filed: 1934-09-07
Abstract: <PICT:0426764/III/1> In the removal of the high boiling components of a solvent mixture from solutions of organic materials, e.g. oils, by stripping the solutions with the vapour of a low boiling component of the solvent mixture, the mixture of solvent vapours obtained is freed from its high boiling vapour and the remaining low boiling vapours are recirculated through the stripping vessel.  The high boiling vapour may be separated by condensing or by irrigating the mixed vapours in a rectifying column with pure low boiling solvent.  In an example, a solution of oil distillates in a solvent comprising nitrobenzol and methyl acetate is stripped under light vacuum in a column 2 by vaporous methyl acetate admitted through an inlet 10. The mixed vapours leaving the column, are freed from nitrobenzol in a cooler 4 and the low boiling vapours comprising mainly methyl acetate, are reintroduced to the column by a pump 9 through an inlet 8, whilst a quantity of pure methyl acetate vapours are admitted to the column through inlet 10 to reduce the partial pressure of the nitrobenzol vapour in the lower part of the column to practically zero.  Part of the methyl acetate may be removed at the byepass 22 and the purified oil at 11.  In a modification, the cooler is replaced by a rectifying column down which liquid methyl acetate is sprayed, and in a further modification complete separation is effected by using both cooler and rectifying column.  Other solvent mixtures, such as benzol and liquid sulphur dioxide, may also be used in the process.

Title: Improvements in or relating to bituminous emulsions
IPC: C08L95/00
Filed: 1924-11-03
Abstract: 246,907. Asphalt Cold Mix, Ltd, and Levy, F. Nov. 3, 1924. Emulsions, making. - Bituminous emulsions are prepared by mixing with liquid or molten bituminous material a proportion (up to about 10 per cent) of an emulsifying agent comprising tannic acid or a synthetic tanning agent, and hot water, with or without a dilute aqueous solution of alkali. The tannic acid may be used in powdered form or as an aqueous extract of oak mark, gall nuts, sumach &c. According to one example, Mexican asphalt is heated to 215-225‹ F. and tannic acid, hot water, and dilute caustic soda solution are added in turn, the mixture being agitated until emulsification is complete. The process may be modified by (1) varying the order or manner of mixing, or by adding the alkali before the emulsifier or by neutralizing the emulsifier with part of the alkali prior to incorporation with the bitumen, (2) replacing the emulsifier in part by a known emulsifier, such as fatty acid or casein, and (3) omitting the alkali or using other alkalies instead of caustic soda. The emulsions are intended for use as binding media in road-making and in the manufacture fo fuel briquettes and as impregnating or preserving agents for wood, metal, stone and the like, and for roofing materials such as felt. Specification 13586/12 is referred to.

To begin a work cycle, a pneumatic cylinder 25 is actuated and a selected quantity of rods 20 are advanced by rod advancing means 21 through the uppermost rows of apertures 51, 52 in baffle plates 19 and in the fixture 45, Fig. 4. The forward ends (22) of the rods 20, Fig. 7 (not shown), are conical and enter into the ends of the tubes 18. The advancing means 21 strikes a limit switch 54 to de-activate the cylinder 25 and supply air to a pneumatic cylinder 30. Rod advancing means 33 advances rods 32 into the ends of the tubes 18 engaged by the rods 20 and while held by the rods 20, 32, the tubes are advanced through the uppermost rows of apertures 51, 52, unil advancing means 33 strikes a limit switch 55. The air flow to the cylinders 25, 30 is reversed and the rods 20, 32 are retracted to their original positions. A table 44 is then elevated to align the next succeeding rows of apertures 51, 52 with the bottom layer of tubes 18 in the hopper 31 and the table is adjusted horizontally since the apertures in adjacentrows are staggered. The table movements are initiated by the advancing means 21 striking a limit switch 57, which also cuts off the air supply to the cylinder 25 and air to the cylinder 30 is cut off by the advancing means 33 striking a limit switch 56. The process is repeated until all the required tubes 18 and the tube assembly is removed from the fixture 45 by opening hinged portions of supports 48 and loosening bolts 49. In the next. tube assembly, the machine cycle is reversed and the first layer of tubes 18 is placed in the lowermost row of apertures 51, 52.
