Patent GB-190323392-A (GB)
Title: Manufacture of Dyestuffs Derived from Anthracene.
Inventor: IMRAY OLIVER
Filed: 1903-10-28
Granted: 1904-09-01
Abstract: 23,392. Imray, O., [Farbwerke vorm. Meister, Lucius, & Br³ning]. Oct. 28. Dyes, artificial; oxyamido anthraquinones; oxyamidobromanthraquinones.-Dye-stuffs are prepared by converting amidoanthraquinone sulphonic acids, obtained by reducing nitrated anthraquinone-osulphonic acid, into oxyamidobromanthraquinones and condensing these with aromatic amines. The 1 : 5 - and 1 : 8 - amidoanthraquinone sulphonic acids are saponified with alkaline earths under pressure and the oxyamidoanthraquinones obtained, either separately or mixed, are heated in aqueous suspension at about 60‹ C., an excess of bromine is slowly added, and the mixture is then heated to about 100‹. The resulting oxyamidobromantbraquinone, or mixture of oxyamidobromanthraquinones, after filtering and drying is a brown or orange-red powder insoluble in water and soluble with great difficulty in most indifferent solvents. The bromine derivative is heated with aniline in a reflux apparatus until the mass is pure blue, when the dye-stuff separates in crystals on adding alcohol. It is little soluble in most indifferent solvents, and crystallizes from pyridine or chlorbenzene in dark blue needles. The corresponding sulphonic acid is obtained by slowly adding a quantity of the dyestuff to an excess of fuming sulphuric acid, and allowing the solution to stand until the product is completely soluble in dilute alkali. The mass is poured into water, and the dye precipitated with common salt. The dye gives a pure blue aqueous solution, and dyes unmordanted wool fast shades of pure blue. The condensation product with ptoluidine, when sulphonated, dyes wool rather greener shades than the aniline product.

Title: Improvements in the Production of Black-magnetic Oxide or Iron.
Inventor: PARKER CHARLES LEONARD
Filed: 1904-03-21
Granted: 1904-04-21
Abstract: 6775. Parker, C. L. March 21. Iron oxides.-Relates to the production of black magnetic oxide of iron, intimately mixed with carbon, from ferrous carbonate, spathose, or other native iron carbonate. The material is placed in an airtight, preferably shallow, vessel of iron or fireclay fitted with a safety-valve for the escape of steam &c., and is subjected to a dull red heat in an oven or retort. The vessels are removed from the oven &c. and allowed to cool before opening. The reaction possibly takes place in the stages :- An exceedingly minute amount of carbonaceous material suffices to start the reaction, and in practice the black oxide of iron left in the vessel from a previous operation is sufficient. If the vessels are opened whilst hot, the carbon takes fire, leaving a brown magnetic iron oxide.

Title: Improvements in and relating to Dynamos and the like.
Inventor: VANDERVELL CHARLES ANTHONY
Filed: 1905-02-13
Granted: 1906-02-08
Abstract: 2918. Vandervell, C. A., and Proctor, W. H. W. Feb. 13. Brakes for dynamos giving a constant output at varying speeds. The armature or field-magnet is normally held stationary by means of a brake drum a and blocks b, but, when the desired speed of the driven member is exceeded, the pressure of the brake blocks upon the drum is reduced, and the armature or field rotates in the same direction, thereby maintaining the relative speed constant. For the purpose of preventing oil &c. from getting upon the surface of the drum, the braking-device is completely partitioned off from the main casing. To avoid differences of braking effect due to the drum being out of truth, the brake blocks are carried by a spring support c, Fig. 2, one end of which is pivoted at d while the other end is held by a block h mounted upon a screwed spindle e and acted on by a spring g fixed to a nut f upon the spindle. The tension of the spring support is adjusted by turning a handle j.

Patent GB-190504692-A (GB)
Title: Improvements in Steam and other Fluid-pressure Regulators.
Inventor: BARLOW HENRY BERNOULLI
Filed: 1905-03-07
Granted: 1905-07-13
Abstract: 4692. Barlow, H. B., [Foster Engineering Co.]. March 7. Pressure - regulating valves.-In the steam or other fluid-pressure regulator shown in Fig. 1, the main valve 6 is controlled partly by the high-pressure fluid, acting through the high-pressure port 20 and the ports 48 on the piston 10, which is attached to the valvespindle, and partly by the low-pressure fluid acting through the port 45 on a diaphragm 30. The high-pressure control fluid first passes into a chamber 19, access to which is controlled by an auxiliary valve 22, pressed towards its seat 21 by a spring 42, and away from its seat by a screwcontrolled spring 32. In the event of the outlet pressure at 3 exceeding that required, the pressure will raise the diaphragm 30 and permit the spring 42 to raise the auxiliary valve 22 and close the high-pressure port 20, thereby cutting off the admission of high-pressure fluid to the piston chamber 9. The pressure in the chamber 9 will then be equalized with that at the out'et 3 by leakage round the piston 10 and the stem 26, the main valve 6 being then raised, to throttle the outflow, by means of the spring 14 and by the fluid entering at 2. As soon as the outlet pressure is reducod, as required, the spring 32 opens the valve 22, permitting access of high-pressure fluid to the piston chamber 9 to open the valve 6 again. The maximum opening is regulated by a screw 16. The outlet pressure is regulated by a screw 34 enclosed in a cap which is locked in position by means of a bifurcated lug engaging a lug 38 on the valvecasing to prevent tampering. To enable the valve to be controlled by fluid pressure at some distant point, or by the outlet of a pump, a tapped connexion is made with the diaphragm pressurechamber 29 ; in this case, the port 45 is closed by means of the screw 46. In the event of the diaphragm breaking, it may be replaced, without the flow being stopped, by slightly opening the needle' valve 44, to admit high-pressure fluid to the chamber 19 although the valve 22 would be closed, and closing the valve 46. A ground shoulder 28 acting against the underface of the cap 27 prevents the escape of fluid about the. stein 26 while the diaphragm is being repaired. Lift valves.-The main lift valve 6, Fig. 3, may be fitted with a removable disk 49 secured by a screw collar 50. The auxiliary valve 22, Fig. 1, may also have a removable disk 23.

The shaft rests on bearings on a hollow standard 1, and carries downwardly - extending flanges 42 to embrace upwardly-extending flanges 43 on the hearths and roof. The shaft is shown provided with two outlet passages 12<b> separated by a diametral coldair inlet passage 12<a>, the passages being connected as shown with the interiors of the stirrer arms, which have central partitions to cause the air to pass along their whole length. The arms may be strengthened by hollow rounded swellings 28, and they have tapered ends connected by pins 26 to sockets at the ends of the removable sleeves 13. Grooves and perforations may be provided in the tapered parts, to allow them to be cooled by the passage of air. The sleeves 13 may be prevented from turning by studs 15 engaging notches in the shaft. In a modification, the interiors of the hollow stirrer arms do not communicate with the interior of the shaft, but are cooled by conduction.
