Abstract: 11,716. Crosland, J. C. H. May 22. Seats; packing, special methods of; gas valves.- In fixing seats of valves which are used for steam, gas or water, &c., a tight joint is ensured between the seat and casing of the valve by shrinking one or more rings c of copper or other material, of elliptical or other crosssection, and preferably made without a joint, on to the exterior of a cylindrical part d of the seat a, and then forcing the latter into position in a casing b, so that the ring is compressed between the part d of the seat, and a concentric cylindrical part e of the casing. The ring c is prevented from slipping upwards by a shoulder formed on the part d of the seat as shown. Instead of shrinking the ring on to the part d, it may be fitted in a recess or dovetailed groove in either the seat or the casing, or partly in a recess formed in each, or the seat and casing may be cast on to the ring, after previously fixing the latter in a mould.

Patent GB-190319973-A (GB)
Title: Improvements in the Manufacture of Colouring Matters Containing Sulphur and of Intermediate Products.
Inventor: JOHNSON GEORGE WILLIAM
Filed: 1903-09-16
Granted: 1904-09-08
Abstract: 19,973. Johnson, G. W., [Kalle & Co.]. Sept. 16. Dyes, artificial.-A rosinduline is obtained, and is subsequently melted with sodium sulphide and sulphur. In an example, hydrochlorate of benzene azo-alpha-naphthylamine is heated with p-amidophenol at a temperature between 160‹-170‹ C. for five hours. In the reaction, the benzene-azo-alpha-naphthylamine is converted into 1-4 naphthylene-diamine, and therefore the latter compound may also be used along with an oxidizing-agent. The melt is lixiviated with dilute hydrochloric acid, and filtered. Trioxyphenyl rosinduline remains as a sandy powder, which is insoluble in water, benzene, and dilute acids, is soluble to a red-violet solution in alcohol and in dilute alkalies, and to a greenblue solution in concentrated sulphuric acid, and is precipitated by acids as red-brown flakes from its alkaline solution. The same body is obtained either by heating for six hours at 160‹-170‹ C. a mixture of o- or p-nitrophenol or p-nitraniline, pamidophenol, a-naphthylamine, and hydrochloric acid, or by melting together a-nitronaphthalene, p-amidophenol, and hydrochloric acid. Another rosinduline is obtained by heating for three hours at 170‹-180‹ C. benzene-azo-a-naphthylamine, pamidophenol, p- or m-nitraniline, and concentrated hydrochloric acid. This colouring-matter dissolves to a reddish-violet solution in alkalies. The first rosinduline obtained may be mixed in solution with water, soda lye, and a mixture of sodium sulphide and sulphur, then gradually heated, and maintained at 160‹-170‹ C. for about five hours. The melt obtained is dissolved in water, and the dye precipitated therefrom by hydrochloric acid. It dissolves in aqueous sodium sulphide to a redviolet solution, and is precipitated by hydrochloric acid. The second rosinduline may be dissolved in soda lye and water, and a solution of sodium sulphide and sulphur added. This mixture is heated gradually to 160‹ C., and maintained for five hours at that temperature. The dye is then dissolved out, and precipitated by hydrochloric acid. The two latter colouring-matters dye unmordanted cotton pronounced reddish-violet shades, and resist the action of light and soap.
