Patent GB-1503465-A (GB)
Title: Pressure operated isolation valve for use in a well testing and treating apparatus and its method of operation
IPC: E21B49/00
Filed: 1976-01-28
Abstract: 1503465 Wells &c. HALLIBURTON CO 28 Jan 1976 [20 June 1975] 03383/76 Heading E1F A normally open valve 150 in the wall of a well bore testing and treating string is closed when the pressure in the well bore annulus above a packer (not shown) exceeds the pressure below the packer by a predetermined amount and is maintained closed, even though the pressure below the packer may be subsequently increased, e.g. during treatment of the well. As described the testing and treating string includes a normally closed ball valve 103 which can be opened to collect a sample of formation fluid and/or to inject a treating fluid into the formation in response to an increase in the pressure of the fluid in the well bore annulus above the packer. The ball 103 is rotated by downward movement of a piston 104, one side of which is acted upon by the fluid in the annulus via port 126. Downward movement of the piston 124 is opposed by spring 127 and by the pressure of an inert gas container in chamber 128. Initially the pressure of the gas in chamber 128 is equalised with the hydrostatic pressure in the annulus by means of a floating piston 129, passage 130 and ports 154, 155. Communication between the passage 130 and ports 154, 155 can be closed by a valve 150 including a sleeve 167 which engages a seal 166 when moved upwardly. The sleeve 167 has faces 169, 173 subjected to the pressure in the annulus above the packer and a face 174 subjected to the pressure below the packer via the internal bore and ports 161. In use, as the string is lowered into the well bore the pressure of the gas in chamber 128 is equalised with the hydrostatic pressure in the well bore. When the required depth is reached the packer is set, sealing off the formation to be tested and/or treated. An increase in the pressure in the annulus above the packer moves the valve sleeve 167 to close the passage 130 and thus prevent any further increase in the pressure of the inert gas. A further increase in the annulus pressure then shifts piston 124 to open valve 103, e.g. to collect a sample of formation fluid. Should the formation be treated by pumping a treating fluid down the string, the pressure below the packer may exceed the pressure above the packer. However the valve 150 is maintained closed during subsequent increases in formation pressure by a floating piston 180 which engages a shoulder 171 on the valve sleeve 167 to hold it closed should the formation pressure exceed the pressure of the inert gas. The valve 103 is closed by reducing the pressure in the annulus to its original value.

Title: Improvements in the manufacture and production of dyestuffs
IPC: C09B47/067
Filed: 1937-02-05
Abstract: Dyestuffs are manufactured by heating compounds of the general formula B-A-R (where B is the radicle of a cyclic compound having in o-position two halogen atoms, e.g. of the benzene, naphthalene, anthracene, anthraquinone, benzanthrone, azanthraquinone, azabenzanthrone or pyrene series, A is a simple linkage or an atomic bridge, e.g. of carbon, nitrogen or a non-metal of group VI of the periodic system or containing two or more of the said atoms, e.g. a carboxylic acid amide group such as -NHCO-, -CONH-, -NHCONH-, -NHCSNH- or -NHCO-CONH-, and R is the radicle of a vattable compound, e.g. of the indigo, thioindigo, anthraquinone or azanthraquinone series) with cuprous cyanide in the presence of a nitrogenous organic base, e.g. pyridine, quinoline or dimethylaniline, if desired in the presence of an additional diluent, e.g. nitrobenzene, alkylbenzenes, naphthalene and its derivatives, phenols, glycol or cyclohexanol, and advantageously in the presence of metals or metal compounds, e.g. copper and its compounds.  The products are useful as vat dyestuffs and as body colours for the preparation of coatings, lacquers and varnishes.  In examples: (1) anthraquinone-2-carboxylic acid 31 : 41-dibromanilide is heated with cuprous cyanide, pyridine and nitrobenzene; the product dyes cotton green shades from a brown vat; similar dyestuffs are obtained from 31 : 41-dihalogenanilides of other vattable carboxylic acids, e.g. of other anthraquinonecarboxylic acids or of anthraquinonecarboxylic acids in which the anthraquinone nucleus contains substituents or has other rings joined to it; (2) 1-(41-chloro-31-bromobenzoyl) - aminoanthraquinone is heated with cuprous cyanide, cuprous bromide and quinoline; the product dyes cotton green shades from a violet vat; similar dyestuffs are obtained from o-dihalogenaroyl derivatives of other aminoanthraquinones or of other vattable amines, or from compounds in which an o-dihalogenaryl radicle is attached to the carbon atom of an azole or pyrimidine ring in a vattable compound. o-Dihalogen compounds of the general formula given above are obtainable by condensing the halide of a carboxylic acid of a vattable compound, e.g. the chloride of an anthraquinone or anthraquinonebenzacridone carboxylic acid, with a dihalogenaniline; or by heating a vattable amine such as aminoanthraquinone with 3 : 4-dichloro- or -dibromobenzoyl chloride; or by reacting vattable carboxylic acid chlorides with o-dihalogen compounds by the Friedel-Crafts synthesis; or by reacting o-dihalogenbenzoyl chlorides with diaminoanthraquinones. The starting materials of the examples above are obtainable by reacting together, in the presence of nitrobenzene: (1) anthraquinone-2-carboxylic acid chloride and 3 : 4-dibromaniline; (2) 1 - aminoanthraquinone and 4 - chloro -3-bromobenzoyl chloride.
