Patent GB-189812679-A (GB)
Title: Manufacture of Naphthacetoldisulphonic Acids and of New Colouring Matters Derived therefrom.
Inventor: IMRAY OLIVER
Filed: 1898-06-06
Granted: 1898-08-20
Abstract: 12,679. Imray, O., [Society of Chemical Industry in Basle]. June 6. Acetylamidonaphthol disulphonic acids, or 'naphthacetol disulphonic acids,' are produced by gently boiling 1 : 8 : 3 : 6-, 1 :8 : 4 : 6-, 1 : 8 : 2 : 4-, and 1 : 5 : 3 : 7-amidonaphthol disulphonic acids with acetic anhydride and glacial acetic acid, or other acetylizing agents, upon an oil bath until a sample gives no colour with nitrous acid. Any diacetyl amido derivative is converted into the monacetyl derivative by distilling off the acetic acid and heating the mixture with dilute sodiumcarbonate solution, or with a dilute acid, or water. The free naphthacetol disulphonic acids are very soluble and are only precipitated by acids from concentrated solutions of their salts. With diazo compounds they yield the same prodncts in acid and alkaline solutions, and they are not attacked by nitrous acid. Dyes, artificial.-Monazo dyes which yield on wool blue-red to violet tints are produced by combining the foregoing naphthacetol disulphonic acids with diazobenzene, or its sulphonic acid, or similar diazo compounds. Non-diazotizable intermediate products are formed by combining the tetrazo compound of benzidine, tolidine, or dianisidine, with one molecular proportion of one of the foregoing naphthacetol disulphonic acids in alkaline or acetic-acid solution, and disazo dyes are produced by combining these intermediate products with a molecular proportion of alpha- or #-naphthol, 2 : 6- or 2 : 7-dioxynaphthalene, 1:4-, 1:5-, or 2 : 6- naphthol sulphonic acid, naphthol carboxylic acid, 1 : 8 : 3 : 6-, 1 : 8 : 4 : 6-, 1 : 8 : 2 : 4-, or 1 : 5 : 3 : 7- amidonaphthol disulphonic acid, 2 : 8 : 6 amidonaphthol sulphonic acid, alpha-naphthylamine, pxylidine, or p-cresidine. The disazo dyes yield on unmordanted cotton violet to blue tints of a brilliant and pure shade. The naphthacetol disulphonic acids may also be combined with the known intermediate products for producing disazo dyes, but the process described above is preferred. The disazo dyes which contain a diazotizable amido group may be diazotized upon the fibre, and then be developed with #-naphthol or m-phenylenediamine, whereby violet to blue, and not black, shades are obtained.

Title: A Black Cotton Dyestuffs and Process for the Production of the same.
Inventor: BANG ADOLF
Filed: 1898-06-13
Granted: 1899-03-11
Abstract: 13,167. Bang, A., [Dahl & Co.]. June 13. Dyes, artificial.-A dye-stuff. which is soluble in water and alkalies and yields absolutely fast brownish-green to intense black shades upon unmordanted cotton according to the strength of the solution, is produced as follows :-Dinitrodiphenylamine monosulphonic acid is melted with sodium sulphide and a little water, then sulphur is added, and the mixture is heated to dryness and then melted at 200‹ to 250‹ C., at which temperature it is stirred until it again becomes dry. If the product is dissolved in water and acidulated, a brownish-black precipitate is formed which redissolves in alkalies with a greenish colour. The dinitrodiphenylamine monosulphonic acid used in this process is produced by boiling aniline sulphonic acid with dinitrochlorobenzene in aqueous solution.

Title: Improved Gas Lighter.
Inventor: VIETINGHOFF-SCHEEL KARL VON
Filed: 1898-09-10
Granted: 1899-06-10
Abstract: 19,307. Vietinghoff-Scheel, K. von. Sept. 10.

Reflectors.-The reflectors H, K are formed of two prisms, the contact faces being straight or slightly curved, and the other faces parallel. The angle of each prism is small, but must exceed a certain small limit. Under certain conditions as to the angles at which the plates must be set it is shown mathematically in the Specification that, if this limit be 7¢‹, the plates H, K will act as reflectors on their upper faces only, and that no confusion will arise from other reflections.

Abstract: 16,263. Spencer, A. Aug. 13. Brakes. hand. Relates to either-side wagon brakes. The brake lever e, which operates the ordinary tumbler levers and push-rods, is connected by the link f to the loose lever a, arranged inside the handle h fast on the cross-shaft b, which has a corresponding handle at its other end or is linked to the handle h' in the manner shown. Both the lever a and handle h pass through the bracket m, the inner convex side of which has a rack n adapted to be engaged by the pawl s formed with the arm t terminating in a cross-piece, or catch q, which may rest, when the brake is off, as in Fig. 1, in notches o formed in the concave sides of the bracket. The lever a has an outward projection k, while to a lug on the handle h is pivoted an arm w which passes through a hole in the catch q. To apply the brakes, a handle h is depressed, causing the shoulder x of the arm w to trip the cross-piece q from the notches o, and the handle h rests on the projection k and descends with the arm a to depress the link f while the pawl s keeps the brakes in the " on " position. On lifting the handle h, it first trips the catch q and pawl s, and the catch then slides up the concave edges of the bracket m, raising the lever a and taking off the brakes, after which the catch q drops into the notches o.
