Title: Improvements in Controlling Systems for Railway Vehicles and Trains.
Inventor: GIBBS GEORGE
Filed: 1903-04-02
Granted: 1903-09-03
Abstract: 7691. Gibbs, G. April 11, A.D. 1902, [date applied for under Patents Act, A.D. 1901]. Stopping engines and trains. - Re-. lates to controlling systems for railway vehicles and trains, particularly those equipped with electric motors and air brakes, and comprises automatic means for applying the brakes and opening the power circuit and thus stopping the vehicles and trains should the signals be over-run. Fig. 1 shows an arrangement in which air brakes are used, and the controller 1 is operated by compressed-air motors 8, 9 governed by electromagnets 13, 14 in a battery circuit controlled by a master - controller 18. A circuitbreaker 121 is arranged to open the circuit when the pressure in the cylinder 131 is relieved. The usual air-brake cylinder 6 is connected by a pipe 19 to the motor 9 to return the controller to the zero position when the brake is applied. The signals are fitted with links and rods to operate a tripping device 33 which is above the track when the signal is at "danger." The car has a branch pipe 34 connected to the train-pipe 7 and provided with a cock 35, which is opened by an arm 36 engaging the tripping-device 33, in the event of the train over-running the signals, and the brakes thus applied and the power circuit opened. The tripping- device may operate a switch arm to open the power circuit and effect the movement of an electrically-controlled air valve to apply the brakes. To prevent the circuit-breaker 121 from being operated each time the brakes are applied, the connections 7, 50, 49, 341 are carried to a fourway cock 351, as shown in Figs. 3 and 4. The auxiliary reservoir 5 normally communicates with the cylinder 131, but, when the arm 36 is tripped, the train-pipe 7 and cylinder pipe 49 are opened to the atmosphere through the opening 51. The movement of the arm 36 may actuate a switch to open the battery circuit and thus open the power circuit; or a switch may be opened by the movement of the brake piston in the brake cylinder.

Title: Improvements in the Manufacture and Production of Disazo Colouring Matters
Inventor: JOHNSON JAMES YATE
Filed: 1903-05-08
Granted: 1904-04-28
Abstract: 10,536. Johnson, J. Y. May 8. Dyes, artificial.-Disazo colouring-matters, which dye wool valuable shades, are produced by combining one molecular proportion of 1 : 5-dihydroxynaphthalene, with either two molecular proportions of one diazo compound, or one molecular proportion each of two different diazo compounds. Some of the dyeings, e.g., those produced by dyes derived from o-amidophenol derivatives, when treated with a chromate or chrome salt turn black, and some are rendered fast to milling by this treatment. In an example, one part of diazotized anyhdrous sulphanilic acid is combined in the cold with one part 1 5 dihydroxynaphthalene. The yellow or red solution so produced is rendered alkaline, and a second part of diazotized sulphanilic acid is added. The liquid is acidified,.and the dye is salted out. The acid bath dyes wool brownish Bordeaux. The dye may be produced in one operation. If 1 :4- or 2 : 8 - diazo-naphthalene suplhonic acid be used, dyes are obtained giving, on wool, blue- and red-violet shades which are rendered fast to milling by a bichromate. The dye obtained from amidosulphosalicylic acid (OH : NH3 : SO3H : COOH = 1 : 2 :4: 6) gives brownish-violet shades. The dye obtained by combining, in one or two steps, two parts of o-amidophenol-p-sulphonic acid with dihydroxynaphthalene gives violet shades which are turned black by bichromates. If o-nitro-o-amidophenolp-sulphonic acid be used, a dye is obtained which gives blue-violet shades which turn greyblack when treated with a bichromate. The dye obtained from p-nitraniline gives brown-red shades. A dye which dyes wool red is obtained by successively combining molecular parts of 1 : :4-naphthylamine sulphonic acid and o-amidophenol-p-sulphonic acid with dihydroxynaphthalene. If the naphthalene derivative obtained from one part of the aniline monoazo colouring-matter be combined with o-diazo-o nitrophenol-p-sulphonic acid, a dye giving brown shades is produced.
