Title: Manufacture of dyestuffs of the dioxazine series
IPC: C09B56/00
Filed: 1935-02-15
Abstract: Oxazine dyes are prepared by heating above about 150 DEG  C. in a high-boiling solvent a diarylaminoquinone of the formula <FORM:0452033/IV/1> wherein R stands for an aromatically bound radicle of an azo-dye which may contain one or more sulpho groups and X means hydrogen halogen or alkyl; an oxidizing agent, a metal chloride and an acylating agent may also be present.  The products may be further sulphonated by means of strong or fuming sulphuric acid. Suitable amino-azo compounds for use in preparing the starting materials (at temperatures below 100 DEG  C.) are aminoazobenzene, aminoazonaphthalene, benzene-azo-naphthylamine, benzene-azo-anthramine, benzene-azoaminodiphenylamine, benzene-azo-aminocarbazole or dyes wherein naphthylamine, anthramine, aminodiphenylamine, aminocarbazole, aminopyrene, aminochrysene are combined as diazo components with aromatic amines; amino-di-or-polyazo dyes may also be used.  The oxazine ring closure may be effected by subjecting the unreacted aminoazo compound and the benzoquinone compound to a heat treatment above 150 DEG  C., and also the diarylaminoquinone body may be converted to the oxazine structure by treating it with strong or fuming sulphuric acid, preferably in presence of an oxidizing agent, whereby a sulphonic acid derivative may be produced.  The unsulphonated products or the sulphonated dyes in the form of their barium or calcium salts, may be used as pigments, for instance for colouring caoutchouc.  The sulphonic acids dye vegetable, animal or artificial fibres (for instance viscose artificial silk).  In examples: (1) the intermediate obtained by condensing p-aminoazobenzene with chloranil is boiled in nitrobenzene containing a little m-nitrobenzene sulphochloride; the product may be sulphonated by means of fuming sulphuric acid (dyes animal, vegetable or viscose artificial silk fibres violet shades); (2) the condensation product of 4-benzene-azo-1-naphthylamine and chloranil is boiled in nitrobenzene containing p-toluenesulphochloride and further sulphonated (green shades); (3) the condensation product of 4-amino-1.2<1>-azonaphthalene and dichlorobenzoquinone is heated to boiling in nitrobenzene containing benzoyl chloride; sulphonation yields a blue-green dye; (4) the intermediate from 4-amino-azobenzene-4<1>-sulphonic acid and chloranil is stirred at 150 DEG  C. with fuming sulphuric acid (dyes blue shades). Samples have been furnished under Sect. 2 (5) of products prepared (a) by heating to the boil in nitrobenzene containing p-toluenesulphochloride the condensation product of 4-(azobenzene-azo)-1-naphthylamine and chloranil); (b) by further treating the pigment product of (a) with fuming sulphuric acid at 80 DEG  C. (green shades).ALSO:Products considered to be dioxazine dyes containing azo groups and to correspond with the general formula <FORM:0452033/V/1> wherein R stands for an aromatically bound radical of an azo-dyestuff and X for hydrogen, halogen or alkyl, are of use in a finely dispersed state for colouring caoutchouc.

Filed: 1955-02-21
Abstract: 765,012. Lixiviating metal - bearing material. SHERRITT GORDON MINES, Ltd. Feb. 21, 1955 [April 10, 1954]. No. 5045/55. Class 82(1) Metal values are extracted from metalbearing material and dissolved in a leach liquor by continuously feeding a slurry of metal-bearing particles and leach liquor and a stream of gas under pressure to the lower part of a vertically disposed column, the column being maintained at a Temperature and pressure above atmospheric, forming in the column a continuously rising turbulent suspension of gas bubbles, particles and leach liquor of substantially uniform cross-section and velocity, without fall back of particles, from the point of entry to the point of discharge of the particles so as to achieve optimum extraction of metal values within the drum by controlling the rate of feeding slurry and gas, and continuously removing gas, particles and leach liquor from the upper part of the column. In a preferred form as shown the bottom of the column 40 is an inverted cone 46 gas being injected at the apex 45, the slurry of particles being fed in at a point above the entry point of the gas stream. The column may be divided into a number of separate compartments 47, 48 and 49 as by inverted cone shaped partitions 41 and 42, adjacent compartments communicating through orifices 43 and 44, the rate of flow of gas, leach liquor and particles through each compartment being approximately the same as the rate at which they are introduced into the column. In a modification the slurry of undissolved particles and leach solution is withdrawn from the column at a point below the top thereof and gas is withdrawn separately from the top of the column. In a further modification the treatment takes place in a number of columns in series, gas and slurry from the top of one column being introduced into the bottom of the next. In this modification used gas may be discharged from the top of one column in the series fresh gas being introduced into the next column

Title: Improvements in or relating to siloxane elastomers
Filed: 1959-02-13
Abstract: An elastomeric solid is made by adding to liquid diorganosiloxanes having a linear structure, Si-bonded monovalent hydrocarbon or halohydrocarbon radicals, a viscosity between 5,000 and 500,000 cs. at 25 DEG C. and contain at least 0,1% of Si-bonded OH groups, from 0,5 to 10% by weight of the siloxanes of a silane of the formula R. Si(OCOR1)3, wherein R is a lower alkyl, alkenyl, aryl or aralkyl group and R1 is an alkyl group containing 1 to 18 C atoms, but excluding methyltriacetoxysilane which is claimed in the parent Specification.  Silanes specified are methyltri-propionoxy, -oleyloxy and -benzoyloxy and ethyltriacetoxy silanes.  The silanes may be diluted with inert powders or octomethylcyclotetrasiloxane.  Fillers, e.g. natural, precipitated and fume silicas, alkoxy modified silicas and oxides of Al, Fe, Zn and Cd and vulcanisation accelerators, e.g. oxalic acid, p-aminobenzoic acid, morpholine, ethanolamine, diethylaminoethanol, methyldiethanolamine, o-toluene sulphonamide and urea, may also be added.  Examples are given in which the siloxanes used are made by heating the cyclic tetramer under nitrogen at 150 DEG C. with aqueous KOH to yield an oil to which water is added in small quantities over a period of about 4 hours.  The mixture is allowed to cool and the KOH is neutralised by adding silica.  The resulting liquid is then heated under nitrogen to remove volatiles and to give the desired oil.  Organotriacyloxysilanes are made by reaction of an organic acid, its anhydride or its alkali metal salt with an organotrihalogenosilane.  In Examples, (1) methyltribenzoyloxysilane is made by the action of methyltrichlorosilane on anhydrous sodium benzoate dispersed in toluene; (2) methyl-tripropionoxysilane is made by progressively heating to gentle boiling (150 DEG C.) a mixture of methtrichlorosilane and propionic acid; and (3) ethyltriacetoxysilane is made by refluxing a mixture of acetic anhydride and ethyltrichlorosilane.  Uses.  For moulding (notably for dental use), for sticking various materials together and for treatment of fabrics.

Abstract: 608,348. Milking-machines. NIELSON, H. Feb. 20, 1946, No. 5354. Convention date, June 21, 1940. [Class 84] The main space at the right hand end of the piston 12 of the pulsator of a milking-machine is connected through ports 37, and 25 &c. with the main suction nipple 26, a smaller space behind an extension 15 being connected with the atmosphere through ports 33, 28. The space at the other end of the piston which starts at atmospheric pressure, is exhausted through a port 38, a frequency-control valve 39, and the suction nipple 26 until its suction overbalances that at the right hand end (which is exerted on part only of the piston 12) and atmospheric pressure on the end 15 moves the piston 2. In its stroke towards the left hand side, the piston uncovers a port 22 of the teat-cup hose nipple 18, which is at atmospheric pressure due to connection at 21, 28 with the air, and aids the piston movement which reverses the connections to the nipples 17, 18 for the teat-cup hoses. The arrangement allows substantial quantities of air to pass through the frequency regulating valve which may therefore be made large so that it does not readily clog. The Specification as open to inspection under Sect. 91 comprises also modifications:-(1) air inlet is through a filter disc alternately to two compartments, one at each end of the pulsator; (2) initial movement of the piston forces compression springs past a dead centre; (3) levers and pistons moving under air pressure aid in completing the piston stroke.
