Title: Improvements in the manufacture and production of anthraquinone derivatives
IPC: C09B1/32
Filed: 1920-10-19
Abstract: Arylaminoanthraquinone compounds are obtained by treating aminoanthraquinones, or their derivatives substituted in the nucleus or in the amino group or both, with metal arylides and primary arylamines.  The metal arylides may be used as such or may be formed in the reaction from metals or metal compounds, such as metal amides. The reaction may be assisted by treatment with weak oxidizing agents, for example blowing air through the mass. According to examples:-1-amino-2-methylanthraquinone is dissolved in excess of aniline and sodium amide is added to the solution in a nitrogen atmosphere; air may be blown in after the first reaction caused by the amide has ceased; the product is 1-amino-2-methyl-4-phenylaminoanthraquinone; 1-amino-anthraquinone similarly yields an aminophenyl-aminoanthraquinone; sodium is heated with excess of p-toluidine and a little nickel oxide in nitrogen, and a solution of 1-amino-2-methyl-anthraquinone in p-toluidine is added; air is passed through the reaction mixture; the product is 1-amino - 2 - methyl - 4-p-tolylaminoanthraquinone; magnesium anilide is prepared by boiling magnesium shavings with aniline and sodium amide, and 1-amino-2-methylanthraquinone is added; the product is 1-amino-2-methyl-4-phenylaminoanthraquinone; aluminium anilide is prepared by heating aluminium shavings with aniline in nitrogen, and 1-amino-2-methylanthraquinone is added, giving 1-amino-2-methyl-4-phenylaminoanthraquinone; the same product is obtained from 1-amino-2-methyl-4-chloranthraquinone, aniline, and sodium amide; 1 : 4-bis-phenylaminoanthraquinone is obtained from 1-phenylaminoanthraquinone, aniline, and sodium amide; 1 : 4-di-p-toluidoanthraquinone is obtained from 1-p-toluidoanthraquinone, p-toluidine, and sodium p-toluidide; an aminophenylaminoanthraquinone is obtained from 2-aminoanthraquinone, aniline, and sodium amide; this product is not 1-phenylamino-2-aminoanthraquinone and yields a different imidazole with acetic anhydride; 1-aminoanthraquinone yields the same product; o- and p-toluidine give corresponding aminotolylaminoanthraquinones; 2-amino-1-chloranthraquinone, aniline, and sodium amide give the same product as 2-aminoanthraquinone; a bis-phenylaminoanthraquinone is obtained from the 2-phenylaminoanthraquinone described in Specification 100,580, aniline, and sodium amide; oxidation of this product by passing air into its solution in aniline containing caustic alkali gives the anthraquinonedihydro-N-phenylphenazine described in Specification 100,581; a diaminophenylaminoanthraquinone is obtained from 2 : 6-diaminoanthraquinone, aniline, and sodium amide.  Benzidine is also specified as a parent amine.

Title: Safety valve having back pressure compensator
IPC: F16K17/08
Filed: 1971-06-28
Abstract: 1329487 Valves DRESSER INDUSTRIES Inc 28 June 1971 [27 July 1970] 30126/71 Heading F2V In a safety valve, wherein premature closing of the valve is eliminated by counter-balancing the back-pressure forces acting on the valve member 22, the valve member is carried by a cylindrical guide 30 and is loosely coupled to one end of a stem 33, the other end of the stem being subjected to the action of a spring urging the stem and hence also the valve member towards the valve seat 21. The guide terminal portion is formed with a flange 60 which co-operates with a housing member 50 to define a variable volume compensator chamber 71, the chamber being in communication with the outlet 17 through radially extending ports 62 which are closable to a predetermined degree by an adjusting ring 63. Formed within the guide 30 and between the guide and a stem-enclosing bellows 42, is a chamber 48 which is in permanent communication with the outlet 17 via radially extending bores 49. In operation the valve opens upon the pressure within inlet bore 13 exceeding a value as preset by the spring. Accordingly, chamber 48 attains a pressure equal to the static pressure within outlet 17 and such pressure acts on the valve member 22 tending to move the latter toward its seat. This outlet-pressure-bias is opposed by the inlet pressure which is fed to the variable volume compensator chamber 71 and which therefore acts on the flange 61, the inlet pressure being fed to chamber 71 by way of a chamber 70 formed between a further adjusting ring 53 and the guide 30, and a leakage path (not shown) formed from chamber 70 and between the guide 30 and the housing member 50. The required upward thrust on the flange 60 is obtained by appropriate adjustment by ring 63 relative to the radial bores 62. The pressure within chamber 71 is said to exert a net positive force, tending to raise the valve member, when the back-pressure in chamber 48 is of a magnitude of at least ten per cent of the set pressure of the valve.
