Patent GB-189719634-A (GB)
Title: Manufacture of a New Amido-base and New Direct Dyeing Polyazo-dyestuffs therefrom.
Inventor: IMRAY OLIVER
Filed: 1897-08-25
Granted: 1898-07-02
Abstract: 19,634. Imray, O., [Schneider, H.]. Aug. 25. Diamidodiphenyldisazoresorcinol is produced by first combining two molecular proportions of diazotized p-nitraniline with one molecular proportion of resorcinol in alkaline carbonate or caustic alkali solution, and then reducing the dinitrodiphenyldisazoresorcinol, thus formed, by mixing it with water, heating to 50‹ C., and gradually stirring in sodium-sulphide solution. The new base is precipitated by addition of sal ammoniac, and then filtered, washed, pressed, and dried. Dyes, artificial.-Polyazo dyes, which have a great affinity for vegetable fibres and are very fast to soap and light, are produced by combining tetrazotized diamidodiphenyldisazoresorcinol in an alkaline, neutral, or weak acid solution with two molecular proportions of the same, or of two different amines, phenols, or amidophenols, or their sulphonic or carboxylic acids. A large number of such combinations are described in the Specification, derived from a- and #-naphthol mono- and di-sulphonic acids, amidonaphthol mono- and di-sulphonic acids, dihydroxynaphthalene sulphonic acids, salicylic acid, hydroxynaphthoic acid, &c. They yield shades varying from green, green-blue, blue, and violet to blueblack, violet-black, and black. Those which are derived from naphthylamine, or from amidonaphthol sulphonic acid in alkaline solution, are further diazotizable in substance or upon the fibre.

Two outlets may be provided, A in the block B and C in the dome D. If the outlet C is dispensed with, perforations E are provided. In a modification, the valve seat G is inserted in a recess formed in a flange at the bottom of the block B.

Granted: 1898-02-12
Abstract: 27,653. Honigmann, F. Nov. 24. Conveyers; elevators.-Coal, gravel, sand, ore, and the like are conveyed from place to place through pipes by means of water currents. Fig. 1 shows a conveyer to which the material is fed by a pipe J. It is discharged on to a sieve S or into a box K. In the arrangement shown, the current is caused by injecting air through a pipe r into the system, but a pump or other apparatus may be used to induce the necessary movement. Fig. 2 shows an elevator provided with a receiver C having valves a and b. When b is shut and a open the receiver is filled. The valve a is then closed and the receiver put in communication with the pipe system by opening a valve c, after which the valve b can be opened and the contents of the receiver carried away. When being filled the water from the receiver falls through pipes d and e into a tank R, from which it is returned to the system by a pump P.

Title: Improvement in Filters for Water.
Inventor: MALLINDER THOMAS
Filed: 1897-11-26
Granted: 1898-11-26
Abstract: 27,785. Mallinder, T., and Greenwood, W. Nov. 26.

Filed: 1900-03-17
Granted: 1901-02-23
Abstract: 5080. Lock, W. H., and Isherwood, H. March 17. Calliper and like gauges.-A micrometer gauge consists of a screw-threaded spindle 16, carrying the ram 17, and a number of screw-threaded tubular parts 14, 11, and 7. Rotary motion of the ram is prevented by a feather 24. The conical end of the part 14 is engaged by a nut 21. The outer threads on the part 11 are right-handed, while the threads on the part 14 and the spindle 16 are left-handed or vice versÔ. By rotating a thimble the ram is advanced or receded at a rate proportional to the sum of the pitches of the right and left handed screw-threads, while when a thimble 3 is rotated the motion of the ram is due to the difference of the pitches. A spring bar 26, secured to the thimble 1 by screws 27, carries a nose 29 adapted to engage a longitudinal slot in the hub 7 so as to lock the thimble with an index mark on it in alignment with a scale on the hub. From this scale the largest readings are taken ; the medium readings are taken from a scale on the part 8 ; and the smallest readings are taken from a scale on the edge of the thimble 3.
