Granted: 1897-09-11
Abstract: 18,353. Fritz, F. Aug. 6. Lighting and extinguishing gas by electricity. Relates to that class of apparatus in which the gas cock is actuated through the agency of the current which ignites the flame. When the core d of the electromagnets c, c<1> is attracted by the magnet c, the gas freely traverses the groove s to the burner ; but when the core d is attracted by the magnet c', the gas-way n is closed by the ungrooved part of the core. In a modification, the core consists of a brass rod with iron pins of different lengths projecting from the ends. The escape of any gas leaking past the core or valve d is prevented by a ' float' or sliding cap k, which is raised by the gaseous pressure when the valve d is open, and which falls by its own weight and seals the outlet n when the valve is closed.

Title: A Process for the Preparation of Guanidine Salts.
Inventor: GOLDBERG ALWIN
Filed: 1897-12-10
Granted: 1898-10-29
Abstract: 29,308. Goldberg, A., Siepermann, W., and Flemming, H. Dec. 10. Guanidine salts.-Guanidine sulphocyanide is prepared by heating ammonium sulphocyanide, mixed with charcoal for increasing the porosity, in an atmosphere of ammonia, together with a metallic oxide such as zinc oxide, or a metallic salt such as lead sulphate at 160‹-175‹ C., and then lixiviating the mass with water. Guanidine hydrochloride is produced when a mixture of zinc oxide and lead chloride is used in the foregoing process, and guanidine sulphate results when excess of lead sulphate alone is used. Guanidine sulphocyanide is also produced by heating a mixture of a sulphocyanide of a heavy metal, such as lead, and charcoal, in presence of ammonia. Double ammonical sulphocyanides, such as cuprammonium sulphocyanide, may also be used if the operation is carried on in a digester. The metals present in these reactions are converted into sulphides.

Title: The Manufacture of Aromatic Compounds by Means of Hydrocyanic Acid and Certain Derivatives thereof.
Inventor: NEWTON HENRY EDWARD
Filed: 1898-06-16
Granted: 1899-04-15
Abstract: 13,453. Newton, H. E., [Farbenfabriken vorm. F. Bayer & Co.]. June 16. Hydroxyaldehydes of the aromatic series are produced by acting upon phenols, or upon acid phenol ethers with hydrochloric acid and hydrocyanic acid, or its salts, or with the double compound HCN.HCl, and then splitting up the resulting aldimide with an acid. For example, to an icy-cold mixture of phenol and dry hydrocyanic acid, aluminium chloride is added, and then dry hydrochloric-acid gas is passed through the mixture for 5 hours, the temperature being allowed to rise to 40‹ or 50‹ C. during the last two hours. The reaction product is precipitated by pouring the mixture upon ice and after boiling it with hydrochloric-acid the p-hydroxy-benzaldehyde thereby liberated is extracted by ether and is purified by means of its bisulphite compound. In a similar manner aldehydes are produced from resorcinol, pyrogallol, resorcinol monomethyl ether, and the like, aluminium chloride being omitted when bodies containing more than one free hydroxy group are used. Benzhydrylamine and leuco bases are produced by acting with sesquichloride of hydrocyanic acid 2CNH.3HCl upon aromatic hydrocarbons, phenols, or phenolic ethers in presence of aluminium chloride, or upon tertiary aromatic amines without aluminium chloride. The compound 2CNH.HCl behaves as if constituted thus : NH # CH.NH.CHCl2 + HCl (hydrochloride of dichlormethylformamidine) and with benzene, for example, it yields a new compound NH = CH.NH.CH(C6H5)2. This compound when heated with alkalies yields formylbenzhydrylamine, HCO.NH.CH(C6H5)2, and this on prolonged heating with caustic alkalies yields benzhydrylamine NH2.CH(C6 H5)2. Similar compounds are obtained from toluene, anisol, and the like. From dimethylamine the leuco base of auramine [N(CH3)2C6H4]2CH.NH2 is first obtained, but this at once reacts with another molecule of dimethylaniline producing the lecuo base of crystal violet.

Title: Improvements in and relating to Apparatus for Generating Acetylene Gas.
Inventor: ADOLFSSON ANDERS EDWARD
Filed: 1899-09-26
Granted: 1899-11-04
Abstract: 19,345. Adolfsson, A. E. Sept. 26. Acetylene.-Relates to generating-apparatus in which the carbide is intermittently fed into water, and consists of a device for preventing the entrance of air into the generator when changing water, and the entrance of gas into the generator from the gasometer when filling in carbide. The generator b is provided with an internal or external water chamber a communicating therewith. This chamber has a water-supply pipe f, a pipe e leading to the gasometer, and a pipe open to the atmosphere at its upper end. Acetylene passes from the generator to the holder by a tube d. The lime sludge is removed by a tube n, arranged as shown either in full or dotted lines, always leaving sufficient water in the generator to seal the end of the outlet tube, and prevent any escape of gas. During this operation, the pressure of gas in the holder forces water into the bent end of the tube d, preventing any escape of gas thereby, and also forces a way for itself through the tube e into the vessel a. When water is poured down the tube f, the gas is displaced and driven back to the holder. The escape pipe l is for allowing water to flow out when the required level is attained. When adding fresh carbide, the pressure in the holder is not sufficiently above that of the atmospheric pressure present in the generator to force gas back into the generator.

Granted: 1900-01-06
Abstract: 24,143. Boult, A. J., [Barthel, G.]. Dec. 4. Vapour burners. -In burners for heating, using petroleum or like hydrocarbons, a stream of vapour from a vertical inlet nozzle a is mixed with air drawn into a horizontal mixing- chamber formed between two plates b, c placed above the nozzle. The upper plate b rests with its projections d on the edge of the top of the burner, and the mixed vapour escapes round the edge of this upper plate, projections f being formed on the edge of the burner for the purpose of forming the flame. The gaseous current between the plates b, c prevents any flashing back of the flame, and this current, together with the current under the plate c, tends to keep the mixing-chamber cool, which effect may be increased by making the chamber of bad conducting material.
