Patent GB-189800930-A (GB)
Title: A New or Improved Generator for Producing a High Pressure Combination Motor Fluid.
Inventor: LOTHAMMER FRANCOIS JOSUE
Filed: 1898-01-12
Granted: 1898-06-11
Abstract: 930. Lothammer, F. J. Jan. 12. Steam and furnace-gas engine furnaces.-Relates to the production for motor purposes of a gas composed of the combustion gases of liquid hydrocarbons and superheated steam. Fig. 1 shows a vertical section of the apparatus, and Figs. 7 and 8 sections at right-angles to each other of the air and hydrocarbon valves employed. The cylindrical generator G is divided up into a series of compartments by horizontal partitions C around which the products of combustion from the burners T circulate. Through the compartments pass steam generating and superheating tubes B having internal ribs. These receive water, which in the chamber C' has been used for cooling the burner. The water, after travelling through the tubes and the enlargement a, escapes as superheated steam into the dome A, where it mixes with the combustion products, and from which it passes by the connection I to the reservoir D, where a further mixing takes place ; it is then ready for use. Ignition is effected by the spraying of the oil against the tube X of ferro-nickel which, when the apparatus is at work, is maintained at a white heat. In Fig. 1 the burner is shown as consisting of the jacket T which receives air from the chamber C<2>, and of the hydrocarbon nozzle fed from the pipe P. In Figs. 7 and 8 the self-regulating burners are shown. Each burner consists of the air valve T' and of the fuel valve t or t<1>, both valves being adjustable by the screwed rod t<2>. On the air valve being closed, the fuel valve and likewise the fuel aperture from the feed-pipe P are opened. On the air valve being open the fuel outlets are closed. The burners are coupled. up in pairs, as shown in Fig. 8, by the two-armed lever L. By this means a forcing back of the gas into the feed-chamber C<2> is rendered impossible.

Title: An Improved Form of Acetylene Generator and Lamp Combined.
Inventor: LEWIS WYNDHAM WILLIAM
Filed: 1898-06-27
Granted: 1899-06-17
Abstract: 14,149. Lewis, W. W., Davis, S. J., and Osmond, F. J. June 27. Acetylene lamps.-In velocipede, carriage, domestic, and d other lamps, a series of carbide chambers is provided to prevent the whole of the carbide from being deteriorated when the supply of water is cut off, and to facilitate re-charging. A number of tubular chambers b, closed at their lower ends by plugs c fitted with tubular extensions e into which the brown paper or other carbide cartridges are inserted, are affixed to the bottom of the water chamber a. From this chamber the water traverses the pipe h, under the control of the cock j, to the first of the chambers b, and percolates through perforations f in the lower end of the tube e to the cartridge. The top of each chamber b is connected by a tube g to the bottom of the succeeding chamber, so that the gas generated traverses each chamber in turn before passing by the pipe k to the burner. Similarly, the water rises in the first chamber b until, after having exhausted the charge of carbide contained therein, it traverses the tube g to attack the carbide in the second chamber, and so on. Should the gas be generated faster than it is consumed, the increased pressure drives back the water and automatically regulates the generation. The form and arrangement of the chambers b may be varied, and the inner tubes e may be dispensed with.

Inventor: JOHNSON GEORGE WILLIAM
Filed: 1898-12-08
Granted: 1899-09-23
Abstract: 25,964. Johnson, G. W., [Kalle & Co.]. Dec. 8. p-Diamidodiphenylamine-o-carboxylic acid is produced as follows:-A solution of sodium chloronitrobenzoate [Cl : NO2 : COOH = 1 : 4 : 6] is boiled with p-phenylenediamine and sodium carbonate or the like, at a reflux apparatus for five hours. Upon cooling, the sodium salt of the nitroamidodiphenylamine carboxylic acid thus formed separates in lustrous brown crystals, and, on acidifying, the free acid is obtained as a brownish precipitate which is somewhat soluble in hot water. The nitroamido acid is reduced by iron filings and acetic acid, the mixture is freed from iron, and the new diamidodiphenylamine carboxylic acid is precipitated from its alkaline solution by excess of hydrochloric acid. It crystallizes in small needles, is readily soluble in hot water, and forms stable salts with mineral acids. It yields a diazo and a tetrazo compound. Dyes, artificial.-Substantive cotton dyes are produced by combining the tetrazo compound of the foregoing diamidodiphenylamine carboxylic acid with amines, phenols, amidophenols, or sulphonic or carboxylic acids thereof. (1) With two molecular components of 1 : 4-naphthol sulphonic acid, amidonaphthol disulphonic acid- K, -H, -S,- or -2R, or amidonaphthol monosulphonic acid-S, or-G, naphthionic acid, or m-naphthylenediamine, greenish to black-blue and red and violetred dyes are obtained.

Title: Improvements relating to the Manufacture of Titanic Acid.
Filed: 1899-06-08
Granted: 1900-04-14
Abstract: 11,964. Matthews, D., and British Aluminium Co. June 8. Titanic acid.-A suitable bauxite, containing titanic acid, is finely ground, sifted, and then gradually stirred into sulphuric acid of 100‹ Twaddell contained in a circular wooden tank a lined with lead. The mixture is boiled by a steam coil b until it becomes pasty. Water is added, and the insoluble matter allowed to settle. The solution of aluminium and iron sulphates is siphoned off to the lead-lined wooden tank c, where it is diluted to about 50‹ or 60‹ Twaddell, and boiled by a steam coil d, whereby any titanic acid present is precipitated. After cooling and settling, the solution is run into an open evaporator e heated by a steam coil e<1>, and is run off into troughs k for crystallization. The cake is broken up into blocks by means of partitions in the troughs. The titanic acid from the tanks a, c is led to a small lead-lined tank f, in which it is boiled, by means of a steam coil g, along with strong sulphuric acid. Titanium sulphate forms, and is extracted with cold water. The solution is run through a filter h to a precipitating-tank i, which is heated by blowing in steam through a pipe j. Sodium carbonate is added to neutralize the free acid, and, if necessary, the iron is reduced to the ferrous state by treatment with sulphurous acid. Boiling is continued until all the titanic acid has separated out, the liberated sulphuric acid being neutralized at intervals. The titanic acid is then filtered, washed in a press, dried, and finally calcined in a small retort at a high temperature.
