Title: Manufacture of Colouring Matters of the Thiazine Series and of Intermediate Products therefor.
Inventor: KEHRMANN FRIEDRICH
Filed: 1900-12-31
Granted: 1901-11-02
Abstract: 23,902. Kehrmann, F. Dec. 31. Phenazthionium compounds of the general formula in which R represents an acid radicle, are produced by oxidizing thiodiphenylamine with chlorine, bromine, ferric chloride, lead peroxide, chromic acid, bichromates, nitrous acid, persulphates, and the like. An example is given in which phenazthionium bromide is produced by acting upon thiodiphenylamine in alcoholic solution with bromine at a temperature not exceeding 15‹-20‹ C. The product separates as dark brownish-green crystals with a slight metallic lustre. When ferric chloride is used as oxidizing-agent, phenazthionium chloride is obtained in the form of its double compound with ferrous chloride. Dyes, artificial, of the thiazine series are produced by a conjoint oxidation of the foregoing phenazthionium compounds with one or two molecular proportions of an aromatic amine. These products are represented by the following formulµ :- The production of the phenazthionium compounds and of the thiazine dye-stuffs may be combined in one operation. Examples are given in which (1) di-anilinophenazthionium chloride is obtained from aniline and the double compound of phenazthionium chloride and ferrous chloride by passing air through a boiling mixture of them ; (2) mono- and di-anilinophenazthionium chloride are obtained by oxidizing aniline and thiodiphenylamine in suitable proportions in alcoholic solution by means of ferric chloride; (3) sulphanilinophenazthionium anhydride is similarly obtained from sulphanilic acid and thiodiphenylamine ; (4) p-acetamidoanilinophenazthionium chloride is obtained from thiodiphenylamine and acetyl-p-phenylenediamine ; and (5) mono-p-acetamidodianilinophenazthionium chloride is produced by oxidizing the preceding product with aniline by means of a current of air. The dyes obtained by these processes dye tannin-mordanted cotton greenish-blue, dark green, and indigo-blue shades.

Title: Improvements in Braiding Machines.
Inventor: CLAREMONT ERNEST ALEXANDER
Filed: 1902-06-13
Granted: 1902-09-04
Abstract: 13,395. Claremont, E. A., and Stratton, J. June 13. Braiding - machines. -Relates to machines for covering electric cables &c. The machine has two tables F, A, in the lower of which are carried spindles carrying a ring of spur-wheels B, all gearing together, and a ring of smaller spur-wheels G, which have hubs G<1> working in holes in the upper table. The hubs G<1> and the holes in the upper table form two sinuous intersecting paths. The wheels B are driven from the pulley C through bevel and spur gearing D, D', E, E<11>. The bobbins b are carried by sleeves I having flanged recessed bases I<1>, working on a spindle H carried in a recessed flanged carrier 0. The base of the spindle H is of two diameters. Surrounding the smaller diameter is a spiral spring secured at its ends to the spindle and to the base I<1> of the sleeve I. This spring keeps the thread taut as the spindles move to or away from the centre of the table. A spring L, adjustably secured to the base 0, presses on the larger diameter J of the base of the spindle, and acts as a band brake to regulate the tension. The flanges 0, o work above and below the top table, and are secured to boat-shaped pieces N<1>, 0<1> by bolts. The boat-shaped piece 0<1> is toothed, and gears with the wheels G. The boat-shaped pieces N' work in the serpentine grooves, and are provided with springs N which act as switches and cause one half of the bobbins to move in the opposite direction to the other half. The springs may, however, be fixed to the table, as shown in Fig. 3, to produce the same result. The thread from a bobbin passes through an eye p on a pivoted lever P, and thence through the eye Q to the braiding-point. When a thread breaks, the lever P drops, and comes in the path of a spring lever, which it displaces, thus causing a latch to be removed from a bar, which falls and disengages a driving-clutch and stops the machine. The cable &c. passes once or twice round a take-up drum driven by worm and spur gearing, and then is wound on another drum.

Abstract: 4510. Crossley, W. J., and Webb, W. le P. Feb. 26. Inertia governors for air and gas engine valve gear. Relates to hit-and-miss governors in which the knife edges do not actuate the admission valve directly, and to improvements in the arrangement described in Specification No. 8704, A.D. 1902, [Abridgment Class Air and gas engines]. The lever B, pivoted at its centre, carries a weight G at its upper end, made in one with a spring- controlled block E, to which is attached the pushing-rod J, and governing-blade H. The lever B is operated by the cam C. While the engine is running below, or at its normal speed, the blade H rests on the block K, and presses it forward until the rod J engages with the projection on the block M, and opens the valve. If the speed is above the normal the inertia of the weight G lifts the governing-blade H out of the recess in the block K, and throws the rod J out of action as shown in Fig. 2. The arrangement may be used to control the pumps or other parts of the engine requiring governing, or may be modified so that the valve opens when the governing-blade H rises above the block K, and remains closed while the blade slides on the block. If preferred, a centrifugal arrangement may be used to raise the governing-blade and pushing-rod out of action. The Provisional Specification states that one lever may operate more than one valve.
