Title: Improved Acetylene Gas Lamp for Cycles.
Inventor: GOSSWEILER KARL
Filed: 1901-07-16
Granted: 1901-10-05
Abstract: 14,506. Gossweiler, K. July 16. Velocipede lamps consuming acetylene gas comprise a waist a, to which are attached the combustion chamber b, the anti-vibration device c, the water chamber d, and the calcium-carbide chamber l, the chamber d by screwing, and the chamber l by pressing it upon the elastic ring m. After the water valve i has been opened and adjusted, the water supply is automatically regulated by the pressure of the gas generated on the water in the drip tube e. The water then percolates through slits n in the tube o to the surrounding calcium carbide, which is compressed beneath the spring-actuated ring q. The gas is freed from water while on its way to the burner by traversing the gauze r and a trap chamber t provided with an overflow pipe v. Should the orifice of the burner w become choked, the spare burner w<1> can be turned into the combustion chamber, the valve x being so arranged as always to cut off the supply of gas to the lower burner. By means of a clamp y and a screw z, the burner may be adjusted to prevent the glass of the combustion chamber from becoming smoked.

Title: Improvements in the Manufacture of Phthalic Acid and Benzoic Acid.
Inventor: IMRAY OLIVER
Filed: 1901-07-31
Granted: 1901-09-28
Abstract: 15,527. Imray, O., [Basle Chemical Works]. July 31. Phthalic and benzoic acids.-Phthalic and benzoic acids are produced by heating nitro-naphthalene, naphthylamines, naphthalene sulphonic acids, naphthols, or their substitution products, such as nitroso-, nitro-, and sulpho-naphthols and the like, as well as the intermediate products formed during the oxidation of these naphthalene derivatives, with metallic oxides or peroxides which are oxidants, and alkali, alkali lye, or alkali lyes and alkaline earths, if necessary under pressure, to over 200‹ C. Examples are given in which alpha- or #-naphthol is heated with caustic alkali or alkali lye and copper oxide, or with iron oxide and a current of air for regenerating the oxide. The product is lixiviated, the solution obtained is freed from unaltered naphthol by nearly neutralizing it with mineral acid and saturating it with carbonic acid, and then the phthalic and benzoic acids produced are precipitated by sulphuric acid and separated in the known way. When nitronaphthalene is used, alpha-nitro-#-naphthol and alpha1-nitro-alpha2-naphthol are first produced at about 100‹-110‹ C. These bodies may be separated, or they may be further oxidized to phthalic acid and benzoic acid by continuing the process. In other examples, alpha-nitroso- #-naphthol is employed, and nitronaphthalene is oxidized by means of soda lye and barium peroxides.
