Title: New emulsions of siccative or semi-siccative oils
IPC: C09K23/00
Filed: 1946-08-02
Abstract: Aqueous emulsions of drying or semi-drying oils are prepared by gradually adding the oil in a thin stream to an agitated aqueous liquid containing an emulsifying agent which is at a temperature of 50 DEG  to 60 DEG  C.  The viscosity of the oil relative to the aqueous phase can be varied, giving either oil in water or water in oil emulsions by the addition of resins for an increase or magent or turpentine for a decrease, whilst the viscosity of the aqueous phase can be varied by concentration or by alkaline or acid reacting agents.  Emulsifying agents specified are gums such as gum arabic, distrin, glucose, molasses or cellulose bisulphate lye.  The emulsions may be used for water colours, for firing pigments or for the agglomeration of foundry sand.  In examples, linseed oil is emulsified by (1) dextrin, and (2) gum arabic.

Title: An improved method and apparatus for cracking oil
Filed: 1928-08-11
Abstract: 295,399. Standard Oil Development Co., (Assignees of Spencer, A. C., and Luster, E. W.). Aug. 11, 1927, [Convention date]. Hydrocarbons, cracking. - In a process for cracking oils by the tube and drum method, condensate from an intermediate stage of the process is led away, reheated and returned to the point from which it was taken. Crude oil is pumped from a tank 75 through a pipe 37 and is pre-heated by passing it through heat exchangers 47, 35, 34, 33 where it serves as cooling medium for hot vapours, after which it passes through an accumulator 19 in which condensed oil from the early part of the condensation is collected, thence through a second series of heat exchangers 27, 26 and thence to the cracking coil 1 wherein it flows first countercurrent and then concurrent with the gases of combustion. From this cracking coil the oil passes to one of two soaking drums 4, 5, used alternately, thence to a separator 15 whence tar is withdrawn into a cooler 17. Vapours pass to a second separator 21, whence the condensate passes back to the separator 15. while the vapours pass to the cooling coils 26, 27 from which condensate passes to the accumulator 19 while vapours pass to a fractionating tower 54. From this, condensate is led by a pipe 44 to the vicinity of the cracking oil, reheated and returned to the tower 54, the condensate which is finally unvolatilized passing back to the accumulator 19 by pipes 31, 31<a>. Vapours pass from the tower 54 to cooling coils 33 - - 35, and thence to a second fractionating tower 46 whence part of the condensate is returned by a pipe 50 to be reheated, re-entering the tower by a pipe 53, while the remainder passes through a cooling coil 70 and a reservoir 72 to the main tank 75 supplying oil. The vapours pass to a heat exchanger coil 47, a cooling coil 64 and a gasoline receiving drum 66 whence the condensate is led off by a draw-off line 68.

Title: Improvements in or relating to apparatus for and method of electroplating the insides of pipes
IPC: C25D7/04
Filed: 1946-08-06
Abstract: 644,854. Rotating electrodes. BART, S. G. Aug. 6, 1946, No. 23244. [Class 41] The inside of a pipe is electroplated, e.g. with nickel, by rotating an anode element within and insulated from the pipe which constitutes the cathode and the container for the electrolyte, both the cathodic pipe and anode element having a surface of substantially cylindrical form and being mounted for rotary movement, each about its own axis and inter-driven to turn in unison, and the axes being horizontal and thus parallel one above the other. As shown, a pipe P is provided with temporary end closures 23 and contains electrolyte 17 to such level as to form a closed gas receiving chamber above it. The pipe is mounted horizontally, e.g. on a cradle, for rotary movement, and a cylindrical anode 45 is supported by insulating means on the interior surface of the pipe in slightly space relationship therefrom. The cradle may be formed by a set of four rollers, one of which at least is power-driven. Each end closure comprises an end-plate 23 temporarily secured in place on the pipe and a fixed plate 34 in which the end-plate 23 is journalled for rotary movement. These two plates are provided, in off-set relation to the centre, with fluid conduits 33, 36 respectively, and in addition the end-plate 23 has a circular groove 32 co-operating with the conduits to provide a circuit for electrolyte which is forced through pipe 35 under regulated pressure. An anode flexible conductor 29 passes into the pipe through openings in plates 34 and 23 of one end of the pipe for connection to the anode 45. This anode comprises a hollow perforated shell 46 of insulating material and a body 47 of loose anode-forming particles, e.g. of nickel, contained within a fabric bag in the shell, which is closed by end-plates 48, 49. The anode may be reciprocated axially of the cathode pipe in sliding contact therewith as the pipe rotates, thereby in turn rotating the anode. Alternatively separate drives may be provided for rotating the pipe and anode, this latter by the application of power to the cable 29. The anode may alternatively be formed by a set of anode bars which replace the body 47 of loose metal particles, the bars being circumferentially distributed within the shell 46. In another form, the anode may comprise an outer nickel shell on a copper cylinder provided at one end with a closure head in the centre of which projects a nipple to receive the end of the anode cable 29 and insulating rings encircle adjacent opposite ends of the anode. The pipe p may be supported on the anode which is power-driven, the pipe is then without end closures and is accommodated in an open bath.

Title: Improvements in the cracking of carbonaceous materials
IPC: B01J21/04
Filed: 1937-08-25
Abstract: 501,736. Cracking carbonaceous materials.; catalytic agents. JOHNSON, G. W. (I. G. Farbenindustrie Akt.-Ges.) Aug. 25, 1937, No. 23340. [Classes 1 (i) and 32] Liquid or semi-solid carbonaceous materials are cracked in' presence of a catalyst containing aluminium oxide and boric acid pre- 'pared by mixing an alumina gel with boric acid. Temperatures from 300-700‹ C. and pressures of 10-200 atmos. may be employed with the addition of gases, e.g. hydrogen, steam, nitrogen or oxides of carbon. In the example, concentrated aqueous ammonia is added to an aluminium nitrate solution to precipitate the gel which is filtered, washed, mixed with crystallized boric acid, and dried at 200‹ C. German mineral oil boiling between 200 and 350‹ C. is passed in vapour form through a chamber kept at 460‹ C., filled with the catalyst shaped to pea-size, a highly anti-knock benzine being obtained without appreciable formation of gases or condensation products. Specifications 359,620 and 485,178 are referred to.
