Abstract: 957,189. Gas turbine blast furnace blowers. HEAD WRIGHTSON & CO. Ltd. Aug. 29, 1960, No. 29770/60. Heading F1G. A gas turbine blast furnace blower comprises one or more compressor means driven from a gas turbine by which a main airstream is supplied to two, or two sets of, combustion chambers fed with gaseous or liquid fuel, one or one set of combustion chambers supplying hot gas to a stove system or pebble type regenerator, the exhaust from the stove system or regenerator being mixed with the hot gases from the other, or other set of combustion chambers before being fed to and expanded in the gas turbine and a second airstream is supplied, after passage through the stove system or regenerator to the blast air supply to the furnace together with one or more recuperators by which the air from the compressor means is heated by the turbine exhaust gases. Air compressed in the compressor 1 is preheated in a recuperator 2 by the exhaust gases of the turbine 9 before use in combustion chambers 7, 8. The combustion chamber 7 supplies hot gases to the stove 5 the exhaust from which is mixed with the hot gases from the turbine 8 before expansion in the turbine 9. The turbine exhaust is also used to preheat the air from a compressor 3 before it is passed through the stove 5 to the blast furnace. The turbine 9 drives the compressors 1, 3 and a compressor 10 supplying blast furnace gas to the combustion chambers 7, 8. This blast furnace gas may be preheated in a recuperator 11. The combustion chambers 7, 8 may be replaced by sets of combustion chambers and, in general, more than one stove 5 would be employed.

The conductor 13 is connected to the fitting 7, which carries an external connector 16, by two stranded leads 12, the ends of which are welded respectively to the fitting 7 and to a terminal 14 mounted, on the conductor 13. The conductor 13 is centred by a ring 15 mounted on the sleeve 2. A hood 11 which is bolted to the fitting 7 closes the bushing. In a modified construction the hood carries an upwardly projecting sleeve to which the conductor is soldered and which serves as the external connector.

Title: Measurement of magnetic fields
IPC: G01R33/04
Filed: 1975-07-22
Abstract: 1506316 Magnetometer ULYANOV N I I PROEKT TEKHNOLOGICHE INST MASHINOSTRENIA 22 July 1975 30529/75 Heading G1N A fluxgate magnetometer includes a magnetic core 3 with series opposed field windings 4, 4' and an output winding 5. The field windings are supplied from a capacitor 9 which is charged from an A.C. supply across terminals 10', 12' during the positive-going half cycle at terminal 10'. During the next half cycle, thyristor 8 is gated on via resistor 13 and the capacitor is discharged through the field windings via the thyristor 8. The discharge current produces opposed magnetic fluxes F' in the core 3, so there is no voltage induced in the output winding. Introduction of a magnetic flux F by a permanent magnet 1, for example, causes the core to saturate when the fluxes produced by the field windings are generated whereby there is a change of flux in the core which induces an output voltage from the output winding thereby gating thyristor 14 into conduction. The thyristor is switched on for intervals each having duration related to the measured magnetic field strength and so the mean current flow varies as the field strength. In a modification, Fig. 3, (not shown) a further core and winding arrangement provides compensation for the earth's magnetic field.

[Class 98 (ii)] Coloured patterns on textile fabrics are produced by treating the fabric with a solution containing a vat dye, a dichromate, and a binding agent capable of becoming insoluble under the action of light in the presence of a dichromate, exposing to light in selected areas, removing the unaffected areas of the binding agent and the associated dye by a suitable solvent or solvents, treating the fabric with a reducing agent for the vat dye thereby causing the resulting leuco dye to be absorbed by the fabric in the selected areas, oxidizing the leuco dye and removing the insolubilized binding agent. The binding agent may be gelatin, casein, shellac, polyvinyl alcohol, cellulose acetate, amino cellulose, or cellulose nitrate, suitable solvents for the unhardened binding agents being specified. In an example, cotton fabric is spread with aqueous gelatin containing ammonium dichromate, dried, again spread with the same composition containing Caledon Jade Green X 300 paste, dried, exposed to light under a negative, washed in hot water, dried, padded in an aqueous solution of sodium formaldehyde sulphoxylate and potassium carbonate, dried, steamed, washed in a dilute solution of acetic acid and hydrogen peroxide, washed in boiling soap solution, rinsed and dried. In a modification the vat dye and the solution containing the binding agent and the dichromate are applied separately.

Title: Improvements in or relating to the preparation of substituted pteridines
Filed: 1947-11-24
Abstract: Substituted pteridines having in at least one tautomeric form the formula <FORM:0656403/IV (b)/1> in which NHR is an aliphatic amino carboxylic acid group or a salt thereof are obtained by mixing together and heating 2-amino-4-hydroxy-6-methylol pteridine with an N-(para - amino - benzoyl) - aliphatic amino carboxylic acid or with a salt thereof.  The preferred para-amino-benzoyl starting material is paraaminobenzoyl glutamic acid which yields pteroyl glutamic acid (folic acid) but others such as p-aminobenzoyl glycine, p-aminobenzoyl aspartic acid and some having a polypeptide linkage such as p-aminobenzoyl diglutamyl glutamic acid may be used.  The process is preferably effected at a temperature of at least 100 DEG C. and it is preferred to heat in an inert liquid or solvent at 180-200 DEG  C., e.g. in ethylene glycol or glycerol and the reaction may be conducted in a pressure autoclave. Dehydrating agents such as zinc chloride may also be added to the reaction mixture.  In examples pteroyl glutamic acid is obtained by heating a mixture of 2-amino-4-hydroxy-6-methylol pteridine in ethylene glycol with (1) the disodium salt of p-aminobenzoyl glutamic acid; (2) with the free acid in the presence of sodium methylate, acetic acid and anhydrous zinc chloride respectively. The starting material 2 - amino - 4 - hydroxy - 6 - methylol pteridine is stated to be a new compound and is obtained by boiling dibromacetonylphthalimide in water, cooling and filtering, adding sodium bisulphite and then caustic soda to a pH of 8.  To this solution an aqueous solution of 2,4,5-triamino-6-hydroxy pyrimidine hydrochloride is added slowly, 2-amino-4-hydroxy-6-methylol pteridine being precipitated.  The latter is then purified by treating a solution thereof in sodium hydroxide with activated charcoal and then with a weak acetic acid solution.  The Specification as open to inspection under Sect. 91 refers to the production of pteridines having the formula <FORM:0656403/IV (b)/2> in which R is OR1 or NR1R11, R1 and R11 being hydrogen or aromatic or aliphatic radicals, by heating a mixture of 2-amino-4-hydroxy-6-methylol pteridine with an aminobenzoic acid or a salt, ester or amide thereof.  This subject-matter does not appear in the Specification as accepted.

If the setting of the dampers moves outside a preselected normal range the movement of the grate is changed to bring the dampers within the normal setting range, when the grate speed returns to normal. If the grate speed variation exceeds a predetermined account, an alarm is operated.
