Patent GB-190007291-A (GB)
Title: Improvements in the Manufacture or Production of Dye-stuffs of the Anthraquinone Series.
Inventor: NEWTON HENRY EDWARD
Filed: 1900-04-19
Granted: 1901-03-02
Abstract: 7291. Newton, H. E., [Farbenfabriken vorm. F. Bayer & Co.]. April 19. Dyes, artificial; quinoneimides.-(1) Quinoneimides of anthraquinone disulphonic acids are produced from the disulphonic acids of dinitroanthrarufin and dinitrochrysazin by reducing these compounds by heating them with sulphur sesquioxide, i.e., a solution of sulphur in fuming sulphuric acid, and then either allowing the melt to stand some time, or more quickly by heating it to 80‹ or 90‹ C., or by adding to the melt sulphuric acid of from 75-95 per cent. The quinoneimides separate in the form of blue needles. If the melt is poured into water, the corresponding diamido compounds are produced, as described in Specification No. 16,574, A.D. 1899. The same quinone imides are produced by acting with fuming sulphuric acid upon the dihydroxylamine derivatives of the disulphonic acids of anthrarufin and chrysazin which are obtained as described in Specification No. 20,649, A.D. 1897. (2) The' quinoneimides are converted by reducing-agents into the corresponding diamido compounds, and by the action of hot water they are converted into violet-red solutions containing the corresponding anthradiquinones, which upon treatment with sulphurous acid are converted into 1 : 4: 5 : 8-tetraoxyanthraquinone disulphonic acids. (3) When the disulphonic acids of dinitroanthrarufin and dinitrochrysazin are acted upon by sulphur sesquioxide in presence of boric acid, the formation of quinoneimides is avoided, and boric-acid ethers of the diamido compounds are formed, and when this mixture is poured into water the diamido disulphonic acids of anthrarufin and chrysazin are precipitated.

Title: Improvements in Electrical Valve Apparatus for Actuating the Air Brakes of Railway Trains.
Filed: 1901-12-27
Granted: 1902-08-14
Abstract: 26,474. Abel, C. D., [Siemens & Hal8ke Akt.-Ges.]. Dec. 27. Brakes.-Relates to electrically-controlled valves for allowing the service and emergency applications of air brakes to be started at the rear end of the train. A switch is placed on the locomotive so that, when the electromagnet 1, Fig. 1, is excited, the stem 5 of the armature 3 unseats the valve 7, and air passes from the train-pipe 12 through the pipes 10, 9 and port 13 to the atmosphere, allowing a service application. When the larger electromagnet 2 is excited, the valve 8 is opened, and an emergency application is effected. The switch may be arranged to excite the magnet 1, as well as the magnet 2, during emergency applications. In the modification shown in Fig. 3, the valve 7 is seated in the valve 8, and, when a weak current is passed through the electromagnet 40, the stem 36 of the armature 33 can only rise sufficiently to lift the valve 7, when air from the train-pipe 38 passes through the chambers 31, 32 and passage 39 to the atmosphere and a service application of the brakes is made. Emergency applications are permitted by passing a stronger current through the magnet 40, and then the collar 37 on the stem 36 lifts the valve 8 and allows a large quantity of air to be suddenly vented from the train-pipe.
