Title: The Manufacture and Production of Secondary Disazo-dyes from Nitro-amido-phenol-sulphoacids.
Inventor: JOHNSON JAMES YATE
Filed: 1898-06-28
Granted: 1899-05-13
Abstract: 14,251. Johnson, J. Y., [Badische Anilin & Soda Fabrik] June 28. Nitroamidophenol sulphonic acids.-(1) o-Nitroo-amidophenol-p-sulphonic acid is produced by carefully nitrating phenol-p-sulphonic acid and then partially reducing the dinitrophenol sulphonic acid thus produced by means of ammonium sulphide. The free sulphonic acid is precipitated as pale grey-brown crystals by addition of hydrochloric acid, or its potassium salt is precipitated by acidefying with acetic acid and adding potassium chloride. This salt forms brown crystals on recrystallization from hot water. (2) o-Nitro-pamidophenol-o-sulphonic acid is produced by nitrating p-amidophenol-o-sulphonic acid, taking care to keep the temperature below zero centigrade. The product is precipitated by pouring the mixture upon ice. It yields brilliant pale reddish-brown crystals when crystallized from hot water, and forms mono- and di-sodium salts. Dyes, artificial.-A new class of disazo dyes of various shades, the more important of which are dark blue and green or practically black fast dyes suitable for dyeing wool, the fastness being increased by treating the dyed goods with chromates. These dyes are produced by combining the diazo compound of an amidonitrophenol sulphonic acid with any suitable middle component, such as alphanaphthylamine or ClÚve's sulphonic acids thereof, and then again diazotizing and combining the resulting diazoazo compound with any suitable end component, such as alpha-naphthol or alpha-naphthylamine. Examples are given in which the following compounds are used, viz.:-(1) o-nitro-oamidophenol-p-sulphonic acid, alpha-naphthylamine, and R-salt; (2) o-nitro-p-amidophenol-o-sulphonic acid, ClÚve's mixed naphthylamine-2<1>- and 3'- sulphonic acids, and R-salt.

Title: Improvements in the Electro-Deposition of Metals.
Inventor: COWPER-COLES SHERARD OSBORN
Filed: 1898-10-19
Granted: 1899-10-14
Abstract: 21,974. Cowper-Coles, S. O. Oct. 19. Metals, depositing. - In electrodepositing metals, such as copper, the cathode or mandrel on which the deposit is made is rotated during deposition at such a high rate of speed as will produce sufficient friction between the deposited metal and the electrolyte to give tough and smooth deposits without the use of the burnishers hitherto used. The hydrogen bubbles are also thrown off, allowing a much higher current density to be used than formerly, the resistance being reduced. In the suitable apparatus shown, the cathode C is carried by a vertical shaft D supported on ball bearings d and rapidly rotated by a pulley d<3>. The current is conveyed to the negative leads by brushes F. The anode B receives the current from mercury cups b and wires b<2>. The shaft D is surrounded by a tube E. The scalloped flange c<4> around the lower end of the mandrel prevents the formation of trees or nodules. The cathode may be lifted out of the bath by the eye e'. In a modification, the driving-gear is arranged above the bath, the mandrel being connected to the driving-shaft by a universal joint.
