Title: Manufacture and use of polyazo-dyestuffs
IPC: C09B43/14
Filed: 1946-07-16
Abstract: Polyazo dyestuffs are manufactured by treating aminoazo dyestuffs with phosgene, and using at least one aminoazo dyestuff of the formula R1-N=N-R2-N=N-R3-NH2 wherein R1 represents the residue of a hydroxybenzene-o-carboxylic acid free from sulphonic acid groups, R2 represents a residue of the benzene series containing a sulphonic acid group and having the azo groups in p-position to one another, and R3-NH2 represents the residue of an amine of the benzene series capable of coupling in p-position to the amino group.  Such aminoazo dyestuffs may be prepared by coupling in alkaline medium a diazotized 1-amino-4-nitrobenzenesulphonic acid or monoacyl - p - phenylenediaminesulphonic acid (e.g. 1-amino-4-nitrobenzene-2- or -3-sulphonic acid or corresponding compounds containing an acylamino group in place of the nitro group) with a 1-hydroxybenzene-2-carboxylic acid (e.g. salicylic acid or 6-methyl-1-hydroxy-benzene-2-carboxylic acid), reducing the nitro group or hydrolysing the acylamino group, diazotizing, and coupling in acid medium with an amine of the benzene series coupling in p-position to the amino group, e.g. aniline (preferably as its o -methanesulphonic acid with subsequent hydrolysis), 1-amino-2-methoxy-5-methylbenzene, m - toluidine, 1 - amino - 2 : 5 - dimethoxybenzene or m-anisidine.  The treatment with phosgene, to produce symmetrical or asymmetrical polyazo dyestuffs, may be carried out in an aqueous medium maintained alkaline in reaction.  The products are suitable for dyeing and printing wool, silk, leather, artificial fibres from animal materials such as casein, superpolyamides and especially cellulose fibres such as cotton, linen, ramie, hemp and artificial silk or staple fibres of regenerated cellulose.  They may be treated in substance, in the dyebath or especially on the fibre with agents yielding metal, e.g. copper, yielding mainly red dyeings. Examples describe the manufacture of symmetrical and asymmetrical p  tetrakisazo dyes from certain of the components specified above, and of a trisazo dye in which the second aminoazo dyestuff is 41-hydroxy-31-carboxy-4-aminoazobenzene, and the after-coppered dyeing of cotton with the sodium salt of the dyestuff obtained by phosgenating the aminodisazo dyestuff 4-amino-41-hydroxy-31-carboxy-1 : 11-azobenzene-2-sulphonic acid --> 1 - amino - 2 - methoxy - 5 - methylbenzene.  Specifications 455,274, 468,362 and 516,076 are referred to.

Filed: 1931-07-10
Abstract: 381,608. Photo-electric cells. ELECTRICAL RESEARCH PRODUCTS, Inc., 195, Broadway, New York, U.S.A.-(Assignees of Stilwell, G. R. ; 1023, West 5th Street, Plainfield, New Jersey, and Prescott, C. H. ; 552, Riverside Drive, New York, both in U.S.A.) July 10, 1931, No. 21493/32. Convention date, Aug. 11, 1930. Divided on 381,606. Drawings to Specification. [Class 39 (i).] A photo-electric material, such as caesium, is deposited on an oxide-coated electrode in a photo-electric cell by first producing the material in the form of vapour in the cell by means of a chemical reaction initiated by heat, and directing the hot vapours to be condensed to a part of the wall of the enclosing vessel of the cell, and then baking the vessel to cause the material to deposit on the surface of the electrode. The invention may be carried out by mounting a broken ring of low resistance material below the light-sensitive electrode, the circuit of the ring being completed by a metal capsule or pill containing a mixture which is heated by induction currents to liberate the photo-electric material, a shield being provided to direct the freshly-liberated vapour away from the cathode on to the surface of the bulb. The detailed descriptionof the method of, and apparatus for, carrying out the invention is identical with that contained in Specification 381,606.

Abstract: The working-up of cellulose into viscose is facilitated if there is incorporated with the former prior to or during the tearing or mercerizing operations a small quantity of methylhexanol, borneol or terpineol, or a mixture of such substances as yarmor pine oil. Amounts of 0,1--0,6 per cent calculated on the cellulose or mercerizing lye are suitable.  By the use of such additions, the alkali cellulose may without maturing be worked up immediately into viscose.  Specifications 344,288, 356,749, and 363,908 are referred to.  The Specification as open to inspection under Sect. 91 refers to the production of cellulose derivatives in general and mentions in particular the production of "cellulose ethyl ester" by treatment of alkali cellulose with "chlorethyl": it contains an example in which a treated alkali cellulose is rubbed up with copper sulphate and the mixture dissolved in ammonia; and it includes the use as agents for the treatment of the cellulose or alkali cellulose of higher monovalent alcohols in general, of hydrogenation products of higher fatty and oxyfatty acids such as Mercerol 25, of products produced during the treatment of hydrogenation products of higher fatty and oxy fatty acids with sulphonating agents such as Leophen M, and of products obtained by the treatment of fatty and oxyfatty acids with sulphonating agents such as turkey red oil and Prastabitol.  This subject-matter does not appear in the Specification as accepted.

Title: Improved composition of a soluble oil
Inventor: PUTMAN JOHN HAROLD
IPC: C10M169/00
Filed: 1949-08-23
Abstract: A water-emulsifiable composition, especially for use as a cutting oil or textile oil, comprises a lubricating oil of viscosity 70-200 Saybolt Universal seconds at 100 DEG F, an emulsifying agent and a minor proportion of an alkali metal benzoate or ammonium benzoate. The lubricating oil may be a hydrocarbon oil or a synthetic oil, but is preferably a mineral oil.  The emulsifying agent may be an oil-soluble metal petroleum sulphonate, preferably sodium petroleum sulphonates having molecular weights between 350 and 450.  The composition may contain an emulsion stabilizer such as an alkali metal or alkaline earth metal naphthenate, preferably sodium naphthanate, or diethylene glycol or a lower aliphatic alcohol such as methyl, ethyl, isopropyl or butyl alcohol.  Anti-foaming agents such as silicone oils or vegetable waxes, particularly candelilla wax, and fungicides such as sodium ortho phenyl phenate may be added and, where transparent emulsions are desired, sodium rosinates may also be added.  Where heavy duty conditions are encountered, it may be desirable to include an oiliness or extreme pressure agent, particularly isopropyl oleate, tricresyl phosphate, chlorinated wax, fatty oils or sulphurized or phosphorized fatty oils.  The benzoate may be formed in situ, for example, benzoic acid may be dissolved in the lubricating oil and the necessary amount of alkali added to neutralize this acid together with any naphthenic, fatty or rosin acids that may be present.  Sodium petroleum sulphonates containing free alkali may also be employed to neutralize the benzoic acid that has been added to the lubricating oil.  In the examples, mineral lubricating oil compositions are described comprising (1) sodium mahogany sulphonates dissolved in mineral oil, sodium benzoate, naphthenic acids, isopropyl alcohol, silicone oil, caustic soda and water, (2) sodium mahogany sulphonates dissolved in mineral oil, benzoic acid, rosin, isopropyl alcohol, silicone oil, caustic soda and water and (3) sodium mahogany sulphonates dissolved in mineral oil, sodium benzoate, naphthenic acids, diethylene glycol, candellilla wax, caustic soda and water.  The compositions of the examples are compared with similar compositions from which the sodium benzoate or benzoic acid has been omitted.  Specification 689,739 is referred to.
