Title: Anthraquinone vat dyestuffs containing sulfohalide groups
IPC: C09B6/00
Filed: 1962-02-09
Abstract: The invention comprises anthraquinone vat dyes which contain at least one oxdiazole ring and at least one acylamino group, especially an aroylamino group, which is substituted by a sulphohalide group, and particularly dyes of the formula <FORM:0954410/C3/1> where X is a direct bond or an arylene bridge, n is 1 or 2, A is an anthraquinone residue, such as an aminoanthraquinonyl or an anthraquinoneacridone residue, and Y is an aroylamino group containing a sulphohalide group. The dyes are made by acylating aminoanthraquinones containing at least one oxdiazole ring with a carboxylic acid halide containing a sulphohalide group, by sulphochlorinating an anthraquinone vat dye containing an acylamino group and either an oxdiazole ring or a group of the formula -CO-NH-NH-CO- and when the latter group is present simultaneously forming the oxdiazole ring, by chlorinating the appropriate vat dye sulphonic acid or oxidatively chlorinating the appropriate isothiouronium compound. Aminoanthraquinones which may be acylated are compounds of the above general formula where Y is hydrogen, reaction products of diaminoanthraquinones with reactive derivatives of dicarboxylic acids containing oxdiazole rings and phenyl- or aminophenyl - oxdiazolylanthraquinones containing a -amino groups. The acylating agents mentioned are derived from the sulphonic acid carboxylic acids of thiophene, naphthalene and substituted and unsubstituted benzene, and from sulphoacetic and sulphochloracetic acids. Examples are given. The dyes vat-dye and print textiles of natural or regenerated cellulose and the dyeings may be coated with polyvinyl chloride.

The lever is raised by the diaphragm 54 of actuator 52 when the vacuum pump 43 is actuated by the unit 28 via cam operated switch 57. The speed of the tub or actuator can therefor be increased during part of the operating cycle. As shown the lever is moved between adjustable stops 39, 40 so that the speed has discreet maximum and minimum values. Alternatively the position of the lever, and thus the speed can be set manually. In modifications the vacuum source may be driven by the motor, or only actuated when the motor is energised.
Patent ES-350352-A1 (ES)
Title: Electrodeposition of resins
IPC: C08G65/26
Filed: 1968-02-10
Abstract: An electrically-conductive body is coated with a resin by immersing the body in an aqueous dispersion of a hydrophilic resin having an acid number of 8 to 70 and being a linear resin containing carboxyl groups and hydroxyl groups, the latter having been formed by reaction of some of the carboxyl groups with an epoxide and being positioned remote from the backbone of the resin, the resin being in the form of a salt with a base to provide dispersed particles of size less than 0.5 micron, passing a unidirectional current through the dispersion with the body as anode to form a film thereon and baking the film to cure it. The dispersion may also contain a waterinsoluble thermosetting aminoplast resin. The hydrophilic resin may be derived from a polyhydric polyether or an addition polymer. The polyether is preferably an aliphatic polycyolic polyether of the formula where n is 10 to 14. This is partially esterified with a monocarboxylic acid and the hydroxy ester is then reacted with a polybasic acid anhydride to provide carboxyl groups without cross-linking the resin. The product is then reacted with an epoxide in stoichiometric deficiency to form a hydroxy ester containing carboxyl groups. The epoxide is preferably a mono-epoxide but may comprise additionally or solely a polyepoxide, e.g. a diglycidyl ether of bis-phenol. The polyether may also comprise, instead of the above polycyclic compounds, glycidyl ethers of aromatic compounds or of glycols. The addition polymers which may be used are copolymers of hydroxyl-containing ethylenic compounds and carboxylcontaining ethylenic compounds. The first group includes hydroxyalkyl acrylates, methacrylates, maleates, crotonates and norbornene and alkyl, methalkyl and orotyl alcohols. The second group includes acrylic, methacrylic, crotonic, itaconic, maleic and fumaric acids and monobutyl maleate. The copolymers are reacted with epoxides as above. The aminoplast resin may be a urea-, melamine- or benzoguanamine-formaldehyde condensate in amount up to 40% by weight of total resin. A pigment, e.g. TiO 2 , and organic solvents may also be present. The base which may be used to convert the resin to a salt may be ammonia but is preferably an amine. The dispersion preferably contains 5 to 15% solids and may be maintained at a pH of up to 10. Voltages of at least 200 are suitable. In Example 1, a metal tank serves as cathode and steel and aluminium panels treated with zinc phosphate are used as the anodes for coating. The voltage is run up from zero to 500. The film is baked at 400 F. to cure.
Patent ES-355490-A1 (ES)
Title: Hydrocarbon production by secondary recovery
IPC: E21B43/243
Filed: 1968-06-26
Abstract: In a method of secondary recovery a production well overtaken by a thermal reaction is converted to become an air or water injection well to maintain or direct the reaction. Air is injected into the central well of a fivespot well pattern in a larger field, in situ combustion of the underground hydrocarbons adjacent the central well is started, and the four outer wells are produced. When the combustion front breaks through at a well this well is converted an air injection well, the remaining outer wells are shut in, the initial air injection well is converted to water injection and a well adjacent the five-spot pattern is produced. The process may be continued following break through in the last mentioned well by keeping one well as an air injection well and converting the other wells to water injection according to which well in the field is required to produce next. If the initial break through is at the wrong well this or adjacent producing wells may be used for water injection to induce the combustion front to break through a desired well so that the process may be continued by injecting air into the desired well after break through.

Title: Method and apparatus for determining the depth of submerged lances and the like
IPC: F27B3/22
Filed: 1972-08-05
Abstract: Method and apparatus for determining the depth of a submerged article with the use of a pressure probe, and in particular the depth of a submerged lance used to deliver a gaseous reaction agent to a metallic bath. The probe is adjacent or within a conduit delivering the gaseous reaction agent to the bath. The pressure at the probe is compared with that above the bath, the difference between the two pressures being proportional to depth. The system can be used in installations where the pressure at the surface of the bath is atmospheric pressure or in cases where the space above the surface is evacuated as in vacuum decarburization of stainless steels and the like. In the former case, the probe is usually pressurized to prevent clogging of the tip. In the latter case, the ambient pressure at the tip of the probe is compared with that above the surface of the bath and the probe pulse-pressurized periodically to prevent clogging.
