Patent GB-189914703-A (GB)
Title: Improvements relating to Carbon Electrodes for Arc Lamps.
Inventor: BREMER HUGO
Filed: 1899-07-17
Granted: 1900-07-17
Abstract: 14,703. Bremer, H. July 17. Arc lamps. -Electrodes are made of carbon uniformly mixed with luminiferous matter such as alkaline earths, or calcium carbonate, fluoride, or silicate; to increase the production of light, and are coated with material adapted to form a fused slag therewith, this dropping off near the arc. The coating also protects the carbons from the air. Suitable coatings are produced by electroplating with metal, or by dipping red-hot carbons in fused boric acid, borax, or a neutral or acid borate or alkaline silicate ; metal coatings are used only on carbons containing at least 5 per cent. of mineral matter.

Abstract: 3673. Newton, H. E., [Farbenfabriken vorm. F. Bayer & Co.]. Feb. 24. Dyes, artificial.-New trisazo dyes, which yield on unmordaunted cotton blue shades fast to light, are produced by first combining a diazo derivative such as diazobenzene, diazonaphthalene.p-diazosalicylic acid, monoacidylamido-p-diazobenzene, or the like, with one molecular proportion of ClÚve's alpha-naphthylamine-#3- or #4-sulphonic acid, secondly, rediazotizing the resulting amidoazo compound and combining the diazoazo product with a second molecule of one of ClÚve's acids; and, finally, again diazotizing the resulting amidodisazo dye, coupling the diazo product with #1-amido-alpha3-naphthol-#4- sulphonic acid, or with an alkyl, alphyl, or acidyl derivative thereof, and, if desirable, splitting off any acidyl groups contained in the resulting trisazo dye-stuff. Examples are given in which diazotized acetyl-p-phenylenediamine, aniline, p-amidophenol, alpha- or #-naphthylamine, and p-diazosalicylic acid are used as first components, ClÚve's acid twice as middle components, and #1-amido-alpha3-naphthol-#4- sulphonic acid and its ethyl derivative as last components. When the first or last component is of such a nature as to confer sufficient solubility upon the dye-stuff, for example, amidosulphosalicylic acid, sulphanilic acid, or the glycine derivative of #1 - amido - alpha3- naphthol - #4 - sulphonic acid, then ClÚve's acids may be replaced once or twice by alpha-naphthylamine.
