Patent GB-190328033-A (GB)
Title: Manufacture of New Tetrazo-dyestuffs with aid of 2:5:1:7- amidonaphtholdisulphonic Acid.
Inventor: IMRAY OLIVER
Filed: 1903-12-21
Granted: 1904-02-11
Abstract: 28,033. Imray, 0., [Soc. of Chemical Industry in Basle]. Dec. 21. Dyeing.-Tetrazo dye-stuffs are formed by combining one molecular proportion of the tetrazo derivative of an aromatic p-diamine of the diphenyl series, either with two molecular proportions of the 2: 5 : 1 : 7-amidonaphthol disulphonic acid, or with one molecular proportion of this acid and one molecular proportion of an aromatic amine, a phenol, a naphthol, an amidonaphthol, or a sulphonic or carboxylic derivative of one of these compounds. The compounds dye cotton and vegetable fibres violet to blue tints. The components may be made in an alkaline or in an acetic-acid solution. The dye-stuffs may be diazotized on the fibre or alone, and developed with #-naphthol or the like. The tint with #-naphthol is indigo-blue, fast to washing. Examples :-(1) Benzidine is dissolved in dilute hydrochloric acid, and diazotized with sodium nitrite. The tetrazo compound is poured into 2:5:1: 7-amidonaphthol disulphonic acid containing sodium carbonate, and heated. The dye-stuff is thrown down by salt. It dyes without a mordant, and may be diazotized and developed on the fibre. (2) Benzidine is tetrazotized, and poured into the 2 : 5 : 1 : 7- amidonaphthol disulphonic acid, to which is subsequently added some 2:5: :7-amidonaphthol disulphonic acid. The dye-stuff is precipitated by salt. (3) Tolidine is mixed with hydrochloric acid and diazotized, and the tetrazo solution obtained poured into some 2: 5 : 1 : 7-amidonaphthol disulphonic acid to which some 1 :4-naphthol sulphonic acid is subsequently added. Reference is made to Specification No. 2614, A.D. 1893.

Patent GB-190408297-A (GB)
Title: Improvements in Systems of Electrical Distribution.
Inventor: HEWITT PETER COOPER
Filed: 1904-04-11
Granted: 1904-08-04
Abstract: 8297. Hewitt, P. C. April 25, A.D. 1903, [date applied for under Patents Act, A.D. 1901]. Vacuum tubes.- To obtain a more nearly uniform direct current in a vapour rectifier, fed either with single or polyphase currents, supplemental current impulses are supplied to the rectifier from the secondary of a transformer in the supply circuit ; such impulses, being nearly opposite in phase to the primary impulses, reduce the intermittent character of the direct current obtained. In one application of this system, for the operation of a mercury vapour lamp 5, the single-phase current mains 1, 2 are connected to an anode 8 and the cathode 7, and to a transformer primary 10, the secondary 11 of which is connected between the main 2 and a second anode 9. The secondary 11 then supplies current impulses to the second anode 9 in the intervals between those supplied directly to the anode 8. An inductance 6 may be provided. With the above arrangement of connections, the lamp may also be used on a direct-current system.

Title: Improvements in and relating to Fluid-pressure Brake Systems for Railway Vehicles, Trains and the like.
Filed: 1904-05-11
Granted: 1905-03-16
Abstract: 10,877. British Thomson-Houston Co., [General Electric Co.]. May 11. Brakes. - A straight air - brake system in which the brakes are adapted to be applied automatically in the event of rupture of the train, and also in which the motorman is enabled to apply the brakes rapidly in cases of emergency, consists of two lines of train-pipes L, T, adapted to be connected together through the ordinary motorman's valve M or M<1>, and an automatic valve V, V<1>, a section of which is shown in Fig. 2, in connection with the air reservoir R, R<1> on each car. The valve casing, Fig. 2, is connected to the reservoir R at r, the train-pipe L at l, the trainpipe T at t, and the brake cylinder B at b. The valve being in the condition shown in Fig. 2, air from the reservoir R can leak through small passages a around the piston A and maintain the pressure in the train-pipe L. To make an ordinary application of the brakes, the motorman moves his valve M so as to connect the pipes L, T. Air from the reservoir R then flows through the valve inlet r, piston passages a, valve outlet l, train-pipe L, motorman's valve M, train-pipe T, valve inlet t, and through a hollow in the stem of the valve F, to the outlet b and brake cylinder. Similarly, on the next car, air from the reservoir R' will pass through the motorman's valve and the automatic valve V<1> to the brake cylinder B'. Thus a simple straightair action is obtained. If, however, the train-pipes are ruptured, or if, in an emergency, the motorman throws his valve wide open to connect the pipes L, T, the sudden lowering of the pressure at the valve outlet l will cause a rush of air from the reservoir through the inlet r, and the piston A will be moved against the pressure of its spring S so as to close the piston passages a, open the valve E, and the valve outlet b. Similarly, on the next car, air from the reservoir R<1> will vent directly into the cylinder B'. Thus, an automatic action and a rapid emergency action are obtained.

Granted: 1905-09-28
Abstract: 25,358. Hipkins, W. E. Nov. 22. Weigh - bridges for railway vehicles. -Relates to improvements on the invention described in Specification No. 7411, A.D. 1902, the object being to compensate for the varying dead weights o f t h e platforms owing to accumulation of dirt &c. Fig. 1 shows the upper part of the steelyard form of apparatus. By turning the handle H, the pinion I, Fig. 5, operates the rack J, rod K, rock-shaft N, and rods 0, P so as to put one or other of the platforms out of action. At the same time, one of the compensating-weights is lifted so as not to act on the rod C<1>. These weights are in the form of levers B, B<1>, Figs. 1 and 5, pivoted at D, D' and acted on by cams F, F<1> fixed to the shaft of the pinion 1. The levers carry adjustable weights Q, Q<1> which are moved if the dead weight of the platform varies. In the form shown in Fig. 6, the connecting-rod transmitting the load from the platforms to the indicating-dial is shown at a. The rods m, n, which throw the platforms out of action, are connected by a lever e to a shaft b provided with a hand-lever. When a platform is thrown out of action, a corresponding weight j or j<1> is thrown into action- These weights are carried by levers h, h<1> pivoted at i, i' and raised or lowered by links g, g<1> hanging from levers f, f<1> pivoted at f<2>, f<3> and acted on by cams d, d<1> fixed to the shaft b. In a further modification, the weighted levers h, h<1> act directly on the rods m, n, and the levers f, f<1> are dispensed with.

Abstract: 12,737. Meyer, L. June 20. Bottles &c., non-refillable.-Relates to stoppers for bottles, jars, casks, barrels, &c., and more particularly to that type of stopper which is provided with spring catches adapted to engage with recesses in the neck of the vessel, so that the vessel cannot be opened without destroying the stopper. According to the present invention, the stopper is made of thin resilient material, such as tin-plate, and is closed at its upper end, which is adapted to be cut off with a knife, or torn off with a key. Figs. 1 and 5 show the application to a bottle b. The neck a is provided with ridges c, and with recesses d adapted to engage projections k on springs i secured in recesses h in the hollow metal or like stopper e, which is closed at the top by a plate g. In applying the stopper, the projections k pass over the ridges c until they reach the recesses d, in which they snap and are retained, a tight joint being obtained by the use of a washer s. To open the vessel, the top portion g of the stopper is cut off. In a modification, the cover-plate g is made separate from the stopper, to which it is secured by a sealing-strip provided with a tearing-tongue. The ridges c and recesses d, instead of being formed in the neck, may be formed in a sleeve cemented therein, and the springs i and projections k may be replaced by a spring split ring k<#>, Fig. 5, seated in a groove h. Other minor modifications of the means of securing the stopper are indicated.

Abstract: 2552. Betts, A. G. Feb. 1. Electric furnaces.-In an incandescence furnace, an enclosed channel 5 contains a liquid conductor, for instance copper matte, metallic iron or lead, &c. which is caused to circulate to and from a bath 1 in the hearth of the furnace by electromagnetic means. Carbon electrodes 6, 10 dip into chambers which communicate, respectively, with the bath and channel.
