Title: Improvements in Electrodes for Electric Arc Lamps.
Inventor: BREMER HUGO
Filed: 1899-07-17
Granted: 1900-05-19
Abstract: 14,704. Bremer, H. July 17. Arc lamps. - Electrodes are made of carbon mixed with large proportions of salts of calcium, magnesium, strontium, or other metals, to increase the production of light, and such that the electrodes contain at least 5 per cent. of fluorine, iodine, or bromine, to form fusible slags with the bases, which fall off in small drops near the arc. Calcium fluoride and cryolite are most suitable ; an electrode may contain 10 to 60 per cent. of the former. To prevent flickering, the electrode should also contain 1 to 10 per cent. of a salt of boron, potassium, or sodium, such as boric acid, borax, or potassium or sodium carbonate or silicate. The salts should be calcined previously, to remove water of crystallization. The lower electrode of a pair should be provided with a glassy coating of borax, a silicate, or other suitable material, on which drops falling from the upper electrode run away from the arc. The upper electrode may be coated similarly, or with metal, to protect it from the air. The Provisional Specification mentions the use of pulverized metals or oxides in the electrodes.

Title: Improvements in the Manufacture and Production of Colouring Matters of the Anthracene Series, and of Intermediate Products relating thereto.
Inventor: JOHNSON JAMES YATE
Filed: 1900-06-05
Granted: 1901-05-25
Abstract: 10,316. Johnson, J. Y., [Badische Anilin & Soda Fabrik]. June 5. Dyes, artificial. - Relates to anthraquinone derivatives and consists in first preparing bromine and chlorine derivatives of the monoalphylidoanthraquinone sulphonic acids which are produced as described in Specification No. 25,080, A.D. 1899, by condensing mononitroanthraquinone sulphonic acids with aromatic amines. This is effected by acting upon the said monoalphylido compounds with various proportions of bromine or of potassium chlorate and hydrochloric acid, with or without a diluent, such as water, glacial acetic acid, or the like. The halogen compounds thus produced are themselves soluble colouring-matters, but they are converted into other colouring- matters of bluish-green to green shades by boiling them with an aromatic amine such as aniline. These products are rendered more soluble by gently heating them with sulphuric acid monohydrate, and the resulting sulphonic acids are isolated by pouring the melt into water and precipitating by addition of common salt.

Granted: 1902-11-20
Abstract: 26,625. Ellis, G. B., [Soc. Chimique des Usines du Rh¶ne, anciennement Gilliard, P. Monnet, et Cartier.] Dec. 30. Vanillin.-Aromatic aldehydes are produced by the oxidation of aromatic hydrocarbons containing an unsaturated alkyl group, such as ethenyl (CH : CH2) or allyl (CH2.CH : CH2), in the side chain, by means of a metallic superoxide, or cobalt or nickel oxides, and sulphuric acid. A large excess of sulphuric acid, and a quantity of an oxidizing-agent less than that theoretically required yield the best results. An example is given in which the p-toluene-sulphonic ester of eugenol, obtained by the action of p-toluene sulphonic chloride on a eugenol salt, is oxidized by sulphuric acid and manganese peroxide at about 100‹ C. The aldehyde produced is isolated in the form of its bisulphite compound, and this is hydrolysed into vanillin and p-toluene sulphonic acid by a mineral acid.
