Title: Process for printing staple fibre of regenerated cellulose with leuco ester salts of vat dyestuffs
IPC: D06P1/28
Filed: 1943-06-24
Abstract: In the printing of staple fibre of regenerated cellulose with ester salts of leuco vat dyes by the process wherein the ester salt is printed on the fibre in conjunction with a chlorate as oxidising agent and an oxidation catalyst, and the colour is developed by steaming, the catalyst used is one which causes the oxidation to proceed more slowly than does ammonium vanadate. Specified catalysts are hydroxides of manganese, iron and cobalt and ferrocyanides, ferricyanides and nitroprussides of the alkali metals.  In examples: (1) a fabric of regenerated cellulose staple fibre is printed with an aqueous preparation containing the sodium salt of the acid sulphuric acid ester of leuco-dibromodibenzpyrenequinone, thiodiglycol, starch-tragacanth thickening, ammonium chlorate and sodium ferrocyanide and the print is steamed, soaped at the boil, rinsed and dried; (2) a similar fabric is similarly printed with the use as dyestuff of the sodium salt of the acid sulphuric acid ester of leuco-dibromoanthanthrone and with an addition of urea to the printing preparation; (3) a similar fabric is printed as in (1) with the use as dyestuff of the sodium salt of the acid sulphuric acid ester of leuco-dichloroisodibenzanthrone; (4) to (6) a similar fabric is printed as in (2) with the use as dyestuffs of the sodium salts of the acid sulphuric acid esters of (4) leuco-a -anthraquinonyl - Bzl - aminobenzanthrone; (5) leuco - dimethoxydibenzanthrone; (6) leuco - dibromo - pyranthrone; (7) a similar fabric is printed with an aqueous preparation containing the sodium salt of the acid sulphuric acid ester of leuco - a  - anthraquinonyl - Bzl - aminobenz - anthrone, thiodiglycol, urea, starch-tragacanth thickening, ammonium chlorate and sodium nitroprusside and the print is steamed, soaped at the boil, rinsed and dried; (8) a similar fabric is printed with an aqueous preparation containing the sodium salt of the acid sulphuric acid ester of leuco-dimethoxydibenzanthrone, thiodiglycol, urea, starch-tragacanth thickening, sodium chlorate, ammonium sulphate, ammonia and ferrous ammonium sulphate, manganese sulphate or cobalt sulphate and the print is steamed, soaped at the boil, rinsed and dried.  Samples have been furnished under Sect. 2 (5) of prints obtained by means of printing compositions containing thiodiglycol, urea, starchtragacanth thickening, ammonium chlorate, sodium ferrocyanide and (I) the sodium salt of the sulphuric acid ester of leuco-dibromodimethoxy-dibenzanthrone; (II) the sodium salt of the sulphuric acid ester of leuco-4-methyl - 6 - chloro - 61 - methoxy - thioindigo; and (III) the sodium salt of the sulphuric acid ester of leuco-8-chloro-1,2-naphththio-51-bromindol-indigo.

Abstract: 541,170. Fabrics &c. folding, and measuring. MONFORTS, J. April 4, 1938, No. 10256. [Class 42 (ii)] While fabric &c. 2 is being folded the middle flat portions A and the end folded portions B, C are measured by different devices which register on the same counting &c. mechanism 3. As shown in Fig. 1, the laying blade 1 is carried by a rod 4 which near the end of each reciprocation moves an abutment 5 or 5<SP>1</SP> to register the length A on the counter 3. The last part of each reciprocation of the rod 4 causes a lever 6 or 6<SP>1</SP> to move to register the length of the end folded portion of 'the fabric &c. on the counter 3 through the gearing 7, 7<SP>1</SP>. The last part-layer at the end of a piece of fabric is measured by moving an indicator 8 or 8<SP>1</SP> level with the end of the fabric. The indicators 8, 8<SP>1</SP> are carried by a chain 9 connected with the counter 3 by gearing 10, 10<SP>1</SP>. As shown in Figs. 3 and 4, the levers 23, 23<SP>1</SP> corresponding to the levers 6, 6<SP>1</SP> are carried by brackets 21, 21<SP>1</SP> simultaneously adjustable by means of screws 20, 20<SP>1</SP>, are connected with the counter 29 by bevel gearing 30, 31, and may be arranged to register the length of the fabric round the curves at the ends of the folds as illustrated in Fig. 5. The folding blade 16, Fig. 3, actuates the counter 29 through a chain 27 and sprocket wheel 28. In a modification, a standard length for each layer of the folded 'material' is measured, the measurement being automatically adjusted according to the thickness of the folds or doubled portions connecting adjacent layers. The measurement is recorded continuously by a counting mechanism. In the first movement of the laying blade, a detector is moved through the thickness of the web, and the movement of the deflector is used to move inwardly stops which limit the movement of the laying blade. In this form of apparatus, the blades of the laying device are resiliently guided in the laying head. Specification 531,887 is referred to.

Filed: 1975-03-06
Abstract: 1502422 Magnesium hydroxide STEETLEY MINERALS Ltd 6 March 1975 [7 March 1974] 10339/74 Heading C1A Magnesium hydroxide is prepared by mixing sea water with alkali in the presence of seed crystals of magnesium hydroxide; the alkali is added in excess and the sea water is separated off from the precipitate to give a thickened slurry containing from 25 to 300 grams of magnesium hydroxide per litre of the slurry; this slurry is then treated with an amount of sea water containing sufficient magnesium ions to react with the excess alkali. Preferably the sea water is mixed with the alkali so that the magnesium hydroxide is precipitated at a pH greater than at equivalence. The seed crystals may be obtained from (i) the suspension of hydroxide formed on reacting the alkali with the sea water, (ii) from the hydroxide slurry obtained by separating off the sea water from the suspension or (iii) from the final magnesium hydroxide product. These seed crystals are preferably present in an amount of from 10 to 35 times the weight of the magnesium hydroxide precipitated. The magnesium hydroxide product may be subsequently treated to obtain caustic magnesia and dead burnt magnesia.

Title: Porous silica free gamma alumina base contacting agents and use thereof
Inventor: JNR JAMES ALLEN ANDERSON
IPC: B01J35/10
Filed: 1959-04-02
Abstract: A porous solid catalyst for use in hydrocarbon conversion comprises a silica-free gamma alumina base and a catalytically active metal component, the alumina base having its most frequent pore diameter (Df) between 60 and 400 , the spread of the range of the pore diameters (D DR) between 20 and 100 , and a pore size distribution factor (PD) above 5, where <FORM:0870509/III/1> The catalyst may be used in the conversion of a hydrocarbon boiling above 450 DEG F. where the ratio of the Df of the catalyst to the average molecular diameter in   of the hydrocarbon is between 1.2 and 4, and the average molecular diameter of the hydrocarbon is above 30 .  The catalytically active metal component, which may be present in an amount of 0.1% to 40% by weight, may be deposited on the alumina before or after it has been treated to obtain the above-mentioned pore characteristics.  Alumina having a low PD factor may be treated in several ways to obtain the desired results:-alumina may be heated in the presence of a pore growth promoter, e.g. MoO3, CoO, NiO, Fe2O3 or cobalt molybdate (which may be the catalytically active metal component or may be removed later) at 1350 DEG  to 1550 DEG F. for 4 to 36 hours in a stream of dry gas, e.g. air; carbon may be deposited on alumina, preferably containing a promoter, then burnt off by heating the alumina in air at 900 DEG  to 1250 DEG F., followed by heating at 1350 DEG  to 1550 DEG F. for 6 to 36 hours; aluminas such as gibbsite and bayerite may be heated without a promoter at above 1300 DEG F.; alumina may be heated in steam at 500 DEG  to 1500 DEG F. for 6 to 36 hours; and material which is removed on heating may be incorporated in the alumina, e.g. hydrogenated corn oil, maleic anhydride, ammonium carbonate, ammonium oxalate, naphthalene, anthracene and hydrazine oxalate, and the alumina heated.  The catalysts may be used in desulphurization, decolorizing, hydrocracking hydroforming, polymerization, depolymerization, alkylation, dealkylation, disproportionation, reforming, isomerization, aromatization, hydrogenation, dehydrogenation and hydrofining.  The hydrocarbon conversion may be carried out 30 DEG F. to 2000 DEG F., at a pressure from atmospheric to 5000 p.s.i.g., and with a liquid space velocity from 0.1 to 30 V/V/Hr.  The conversion may be in the presence of hydrogen, nitrogen, air, carbon dioxide, methane, ethane or naphtha fractions.  When hydrogen is present the temperature may be 400 DEG  to 1000 DEG F., the pressure 200 to 5000 p.s.i.g. and 100 to 10,000 standard cubic feet of hydrogen per barrel of feed may be used.  In examples catalysts are prepared by heating gamma alumina containing cobalt molybdate at several temperatures and for several periods of time, the pore characteristics are determined, and the catalysts are used for the hydrodesulphurization of gas oil, the hydrofining of lubricating oil, and the hydrogenation of asphalt.
