Patent GB-190307394-A (GB)
Title: Improvements in the Manufacture and Production of Anthracene Colouring Matters and Intermediate Products
Inventor: JOHNSON JAMES YATE
Filed: 1903-03-30
Granted: 1904-02-04
Abstract: 7394. Johnson, J. Y., [Badische Anilin & Soda Fabrik]. March 30. Dyes, artificial.-Anthraquinone #-monosulphonic acid is treated with concentrated sulphuric acid and either mercury or a mercury salt in the presence of nitrous acid and of either phosphoric or arsenic acid. A new polyhydroxyanthraquinone sulphonic acid (a purpurin sulphonic acid) is obtained. This yields bluish-brown shades on chrome-mordanted wool, and blue-red shades on alumina-mordanted wool, while on unmordanted wool in the acid bath it produces bluish-red shades. This sulphonic acid, when treated with aromatic amido compounds, forms colouring- matters which can be directly employed for dyeing. The reaction may be assisted by boric acid, a salt of an amido compound, hydrochloric acid, hydrobromic acid, hydrofluoric acid, sulphuric acid, phosphoric acid, benzoic acid, acetic acid, zincchloride, &c. The amido compounds used may be aniline, n-toluidine, p-toluidine, xylidene, pphenylenediamine, benzidene, alpha-naphthylamine, #-naphthylamine, &c. In an example, sodium nitrite is gradually stirred into sulphuric acid, and then the dry sodium salt of anthraquinone #-monosulphonic acid is added, followed by metaarsenic acid and mercury sulphate. The mixture is boiled for about two hours, allowed to cool, poured into water, and boiled, and then common salt is added, and the liquid cooled and filtered. The product may be purified by solution in water, and reprecipitation by hydrochloric acid. This product can then be heated with aniline in an autoclave at about 160‹ C. for about 3 to 4 hours. The excess of aniline is driven off by steam, and the colouring-matter thrown down by salt, or separated out by pouring into dilute hydrochloric acid. It dyes unmordanted wool from the acid bath violet, and chrome-mordanted wool darkblue. The first product may be heated with aniline in a reflux apparatus at about 135‹ C. until the mass becomes red-blue. Or the first product may be heated with dry boric acid and aniline at about 135‹ C. until it becomes red-blue. Or it may be heated in a reflux apparatus at about 135‹ C. with aniline chloride and aniline. The excess aniline is driven off by steam. This colouring-matter dyes unmordanted wool from the acid bath, and chrome- or aluminium-mordanted wool, rather redder shades than the last one. Finally, the first product may be heated in a reflux apparatus with p-toluidine and absolute alcohol at about 135‹C. When cold, the product is poured into dilute hydrochloric acid. After drying, the dye will dissolve in sulphuric acid, yielding a blue-red solution, which on the addition of boric acid acquires a greenish tint. It dyes chrome - mordanted wool a bluish - black. On treatment on the fibre with a chromate, the shades become gray-blue.

Patent GB-190326259-A (GB)
Title: Improvements in Apparatus or Means for Regulating or Governing the Speed of Engines Employed in Driving Electric Current Generators
Inventor: JOHNSON JAMES YATE
Filed: 1903-12-01
Granted: 1904-02-04
Abstract: 26,259. Johnson, J. Y., [Electrizitats Akt.-Ges. vorm. W. Lahmeyer & Co.]. Dec. 1. Dynamos, regulating. -Relates to an electric control system for governing engines driving dynamos, and to its application in distribution systems provided with buffer or energy-storing batteries or masses. The governor of the engine is accelerated or retarded in its action, as may be required, by means of a solenoid in the dynamo circuit, the solenoid core being suitably connected to the governor sleeve. As shown in Fig. 1, the solenoid S and core K are arranged to accelerate the action, the effect of an increased load and current being to speed up the engine and so to reduce fluctuations. The core K may otherwise be placed under the solenoid S, so that the action is reversed, an increase in load having the effect of slowing down the engine. This second arrangement is used in the case in which buffer storage batteries in parallel to the dynamo supply the necessary additional current during periods of increased load. The increased fall in the dynamo voltage caused at such periods by the arrangement described allows the batteries to come into action immediately the increase occurs. When the dynamo and batteries are to be used independently at different times, the core K is hung between two solenoids, which are placed in a vertical line and may be switched into and out of circuit independently. The second arrangement is also applicable to the case in which the dynamo supplies current to alternating-current motors provided with energy-storing masses. When the load increases, the solenoid and governor act to decrease the speed of the dynamo and therefore the frequency of the current supplied to the motor, which may be synchronous or asynchronous. With either type of motor, the speed is then reduced, allowing the energy-storing masses to come into action. In the case of asynchronous motors, resistances may, in addition, be switched into the motor secondary circuit, as usual, for the same purpose. The solenoid may be in a shunt from the main circuit, or may be fed by a transformer. The current from the solenoid may be regulated by a variable resistance operated by the governor of the engine. The control system may be modified so that its action depends, not upon the energy required, but upon the speed of the motor carrying the buffer masses. In this case a governor on the motor regulates by a resistance the current flowing through the solenoid ; the two methods may be combined, if desired. The system may be modified by directly controlling the supply of power to the engine, instead of controlling the governor.

Granted: 1905-03-30
Abstract: 7526. Pieper, H. March 30. Locomotives and motor vehicles.-In motor road vehicles, cars running on rails, and the like propelled by an internal-combustion engine coupled to an electric dynamo and battery of accumulators, regulation of speed, carburetting, and the ignition device are simultaneously controlled by one or two hand or foot levers. In the circuit of the compound or shunt wound dynamo 1, which acts as a motor at starting, is a rheostat 4 for the introduction of resistances in the armature circuit, which are gradually cut out by the lever 5. This lever also introduces resistance in the shunt circuit, whereby the field is diminished and the speed increased. The lever 5 also closes the engine ignition circuit, which draws its current from some of the elements of the secondary battery, by the copper segments 19, 20. A rod 6 coupled to the lever 5 is connected to the spark-controlling device cf the engine. This rod has a pin 11 fitted into a fork working a disc 12 with sector-shaped openings forming a second air inlet. The size .of these openings is chosen so as to maintain a uniform explosive mixture. Two levers may also be used, one for introducing resistance into the armature circuit for starting the vehicle, and the other for the shunt-circuit resistances, the latter being connected to the sparking and carburetting devices. The shunt circuit may also be varied by changing the air gap ; if two dynamos are used, the lever may be used to connect them in series or parallel.
