Title: Process for the conversion of hydrocarbon oils
Filed: 1939-04-12
Abstract: 534,518. Cracking oils. MOND, A. L. (Universal Oil Products Co.). April 12, 1939, No. 11129. [Class 32] Hydrocarbon fractions of low boiling range containing large proportions of gasoline of low anti knock value, e.g. naphtha, are cracked at elevated temperatures to obtain a gasoline of improved anti knock characteristics which is stabilized by distillation, the distillate obtained is purified by passing it in the liquid state through clay purification towers and thence without loss of heat to a fractional distillation zone in which polymers are removed, and returned to mix with the conversion product, and gases freed in the stabilization are recovered by absorption in a distillate which is mixed with the final gasolins product. Charging stock is fed to tower 3 where it is used as absorption oil to recover rich fractions from the gases produced in the process. The oil with absorbed fractions is passed through line 4, 7 to cracking coil 9 maintained at 510-566‹C. and the cracked products, cooled to 357‹C. by cooling oil injected through line 16, are passed into the lower evaporator portion 14 of tower 13, the vapours formed being fractionated in the upper part 13. Unevaporated residual liquid is withdrawn through line 18 and flashed with reduction of pressure in column 21 the vapours formed being condensed in cooler 27 and collected in receiver 30 while residues are withdrawn through line 23. The distillate from receiver 30 may be re-cycled to tower 15, while reflux collecting on plate 14<SP>1</SP> may be re-cycled to coil 9. The vapours of desired end point pass off through line 40 and are condensed in cooler 42 the distillate being collected in receiver 45 where it is separated from gases and then pumped by pump 48 into the stabilizing tower 51, where unstable fraction are distilled off by heat from a reboiler coil 58 and are passed through condenser 61 to receiver 64. The stabilized gasoline is removed through line 74 and fed through heat exchanger 79 by which its temperature is controlled to range from 150- 190‹C. in the case of fresh clay and 177 to 233‹C. in the case of less active clay, into one of a pair of clay towers 82, 85 used alternatively. The absorbent clay may comprise fuller's earth, montmorillonite diatomaceous earth &c. supported on perforated plates 88, 89. A plurality of towers arranged in series or in parallel may be used. The treated distillate is removed through line 96 and heat exchanger 97 to tower 100 where it is redistilled to separate a heavy polymerized fraction which is fed through line 106 to the evaporator 14, and a stabilised gasoline which is recovered through line 111 and condenser 113 to receiver 116.

Title: Manufacture of copper clad steel plates
IPC: B23K20/227
Filed: 1952-05-06
Abstract: 699,067. Making composite sheets. LUKENS STEEL CO. May 6, 1952 [May 7, 1951], No. 11378/52. Classes 83 (ii) and 83 (iv). Rolling, brazing.-A method of making copper-clad steel plates comprises electrodepositing a layer of nickel on a face of a plate of oxygen-free copper, securing it in contact with a steel plate or ingot, heating the composite assembly uniformly throughout to between 1550-1800‹ F. and then rolling it to reduce the thickness of the assembly to between “ and <SP>1</SP>/ 25  of its original thickness, the reduction in any one roll pass not exceeding # inch. When the thickness is within 10 per cent of that desired, the reduction per pass is preferably no greater than <SP>1</SP>/ 16  inch. The copper is preferably phosphorus de-oxidized copper having a thickness of from # inch up to one inch. The steel is preferably carbon steel or low alloy steel between two inches and fifteen inches thick. One face of the copper is cleaned and pickled in known manner and given a nickel coating of from 0.001 to 0.020 inch thick and preferably between 0.002 and 0.005 inch. One face of the steel slab is freed from scale as by grit blasting. The copper plate is smaller than the steel plate and if desired two assemblies may be secured together for bonding, the non- coated faces of the copper plates being placed together with a non-welding material therebetween and steel spacers being welded between the edges of the steel slabs. The copper plate of a single assembly may be similarly secured by a second steel plate and spacers, non-welding material being used between the copper and the second steel plate. The assembly is preferably heated to between 1600‹ and 1725‹ F. before rolling. In a specific example two plates of phosphorus deoxidized copper 74 inches long, 48 inches wide and # inch thick and two slabs of carbon steel 78 ¥ long, 52# wide and 3# inch thick are assembled as above described, the nickel plating being 0.003 inch thick. The assembly is heated to 1700‹ F. and rolled down to 1“ inches thick, the reduction per pass being 3/ 16  inch. There follows two reductions of <SP>3</SP>/ 32  inch and then the reduction per pass is gradually reduced until a final thickness of one inch is obtained to provide two copper-clad steel plates each 240 inches long, 50 inches wide and ¢ inch thick.

Title: Improvements in the preparation of photographic emulsions
Inventor: POLLA-MATTIOT GUIDO
IPC: G03C1/053
Filed: 1958-04-10
Abstract: Synthetic amphoteric polymers for the preparation of photographic silver halide emulsions (see Group XX) consist of a methylene chain alternate carbon atoms of which are singly or doubly substituted. One substituent of each of these alternate carbon atoms is an acidic or basic group and the second substituent, if present, is either alkyl or aryl.  The polymer is necessarily insoluble in water over a range of pH values and soluble beyond both limits of the range. Preferably, the acidic groups are carboxyl and the basic groups are pyridine or diethylamine ethyl ester.  In the examples vinyl pyridine is polymerized, in toluene in the presence of benzoyl peroxide, with methacrylic acid or a mixture of methyl methacrylate and methacrylic acid.  In a further example di-ethylamine ethylmethacrylate is polymerized in acid aqueous solution with methacrylic acid in the presence of potassium persulphate.

Title: Electrodialysis
IPC: B01D61/46
Filed: 1964-03-20
Abstract: <PICT:1044394/C6-C7/1> <PICT:1044394/C6-C7/2> An electrodialysis apparatus comprises ion permselective membrane material formed into a helical construction, a cover disposed about the helical construction, and electrodes disposed beyond the ends of the helical construction, the helical construction and cover defining at least one helical liquid treatment path between the electrodes. Fig.1 should cation selectively permeable material 33 and electrodes 41,42. Streams of liquid wash the electrodes.  Liquid to be treated is intro-duced at 27, a concentrated stream flows from 28 and a dilute stream from 29.  In operation, anions are drawn downwards towards the anode 42 but cannot penetrate the membrane and remain on its upper surface. Cations are drawn upwards through the membrane and at the membrane's upper surface, together with the anions, form a more concentrated solution.  The solution at the membrane's lower surface is more dilute.  The more concentrated solution is of greater density and tends to flow downwards under gravity.  The helical membrane is built up from separate membranes 30 (Fig. 4, not shown) joined together and located around an axial rod between the turns of a plastic strip 34 (Fig. 5 not shown) around the rod. The lower convolutions may be spaced by a greater distance than the upper convolutions.  Fig. 11 shows a pleated or crimped cation selectively permeable membrane 73 twisted to form a double helical path. Electrodes 55, 56 are mounted on studs 53, 54 on end caps 51, 52 and retained thereon by rings 57, 58.  Streams of liquid wash the electrodes.  Liquid to be treated is introduced at 65, 66. Concentrated liquid is drawn downwards gravitationally or centrifugally and is removed at 67, 68.  Dilute streams are removed at 69, 70.  Fig. 12 (not shown) illustrates a membrane comprising joined-together strips of selectively anion and selectively cation permeable material 78, 79.  This membrane is pleated and twisted into a helical construction (Fig. 14 not shown) to provide two intertwined liquid paths one of which serves as a concentrating cell C and the other as a diluting cell D. The membrane may be placed in a casing 50 as in Fig. 11.  Tubes 65, 66 may be blocked and liquid to be treated introduced at 67, 68 to flow from tubes 69 and 70 as concentrated and dilute streams. This embodiment functions as a conventional electrodialysis stack without regard to gravitational orientation.
