Patent GB-190301151-A (GB)
Title: Improvements in and relating to Air Pressure Brakes for Railway and Tramway Vehicles
Inventor: HILDEBRAND WILHELM
Filed: 1903-01-16
Granted: 1903-04-16
Abstract: 1151. Hildebrand, W. Jan. 16. Brakes.-Relates to direct-acting air-pressure brake systems, in which the air for service applications is taken from the main reservoir while that for emergency applications is supplied from the auxiliary reservoirs. Fig. 1 shows an equilibrium valve and its connections for effecting these objects. On admitting a small quantity of air to the train pipe a, it passes through the open valve c to the brake - cylinder passage d, the valve e remaining balanced. A quick rise of pressure in the pipe a causes the air to close the valve c and lift the piston e and open the small flange ports k, i, thereby allowing air from the pipe m connected to the auxiliary reservoir, to pass slowly to the brake cylinder and rapidly to the pipe l so as to increase rapidly the pressure in the pipe a and ensure the simultaneous action of all the valves e in the train.

Title: Improvements in the Manufacture or Separation of Titanium Compounds.
Inventor: DREHER CARL
Filed: 1903-01-26
Granted: 1903-11-26
Abstract: 1835. Dreher, C. Jan. 26. Titanium oxides.-Raw materials containing titanium with iron, aluminium, or other similar impurities are, for the separation of the titanium, dissolved in an acid, such as sulphuric acid, hydrochloric acid, or oxalic acid, or alkali bisulphate, and the solution then treated with nascent hydrogen. The titanium separates out in the form of a blueish precipitate consisting of a lower oxide, after the solution has been nearly neutralized by the addition of an alkali &c. or compounds such as sulphites, acetates, formates, &c., which combine with the acid and do not dissolve the titanic oxide. The nascent hydrogen may be produced by adding tin, zinc, iron, or sodium amalgam to the solution, or by electrolysing the solution. The blue hydrated titanum oxide is soluble, and may be used as a reducing-agent for printing or bleaching purposes. It can also be converted into the higher or white oxide by exposure to air, peroxides, sulphurous acid, or other oxidizing-agents. Two examples are given of the treatment of bauxite residues containing ferric and titanic oxides, the necessary hydrogen being produced by electrolysis of the solution and by means of zinc.
