Title: The Production of a New Trioxynaphtalene and Dyestuffs Deriving therefrom.
Inventor: RANSFORD ROBERT BOLTON
Filed: 1898-12-27
Granted: 1899-10-28
Abstract: 27,345. Ransford, R. B., [Cassella & Co., L.]. Dec. 27. 2 : 3 : 8-Trioxynaphthalene is produced from the 2 : 3 : 8-trioxynaphthalene-6-sulphonic acid, which results from the melting of 2-naphthol-3 : 6 : 8- trisulphonic acid with alkalies, by heating it with water in an autoclave for five hours at a high temperature, for example, at 210‹-220‹ C. Upon concentrating and cooling the solution, the new product separates in small light brown needles which melt at 164‹-165‹ C. It is fairly easily soluble in water, very easily in alcohol and ether, and scarcely soluble in benzole or chloroform. In alkaline solutions, it is turned dark brown by air, and ferric chloride gives an intense blue coloration to its solution Treatment with acetic anhydride and sodium acetate converts it into a triacetyl derivative which melts at 125‹-126‹ C. Dyes, artificial.-The foregoing trioxynaphthalene, when combined with diazo compounds in weak acid solution, yields azo dyes in which the diazo compound enters in relation only to the alpha-hydroxyl, leaving the two #-hydroxyl groups free, and which, consequently, are capable of forming lakes with metallic mordants like alizarin dye-stuffs. When non-sulphonated or carboxylic diazo compounds are used, the dyes produced yield absolutely fast shades on mordanted cotton. Sulphonated diazo compounds may be used for producing wool dyes. The shades produced are in all cases brown to black. Examples are given in which the new trioxynaphthalene is combined with the diazo compounds of m-nitraniline and of naphthionic acid, respectively.

Granted: 1900-06-02
Abstract: 15,747. Tomkies, W. H., and Webb, W. C. Aug. 1. Clutches; brakes.- Relates to clutches for free - wheel driving - mechanism and backpedalling brakes. In the arrangement shown in Fig. 2, the hub g carries two flanged collars h, i between which the chain-wheel a is mounted. The flange k is formed with a series of recesses on its face, and the chain-wheel has holes d passing obliquely through it and opening into grooves on each face, these holes each containing a clutch ball m. A ring p placed between the chain-wheel and the flange n is held from rotation by connection with the frame, but is free to move laterally to a certain extent. This ring is also formed with recesses. The flange n is covered with vulcanized fibre &c. to form a brake surface. During forward driving the balls lock the chain-wheel to the flange k. When coasting, the balls are forced back into the holes d, and back-pedalling then causes them to pass to the other side and act on the ring p, thus forcing it against the flange n and at the same time pressing the chain-wheel against the flange k, so as to brake the cycle. In a modification, the holes in the chain-wheel are replaced by grooves on each of its faces, and two sets of clutch balls are used. In this case, the flange k and ring p are formed with annular grooves instead of recesses. According to the Provisional Specification, the ring p may be arranged so as to be capable of partial rotation by the rider to apply an additional brake.

Title: Improvements in or relating to the Step by Step Rolling of Tubes and Apparatus therefor.
Inventor: LAYBOURNE RICHARD
Filed: 1900-08-03
Granted: 1901-09-03
Abstract: 13,985. Laybourne, R., Marsh, C. W. E., and Price, B. Aug. 3. Rolling; forging.-Relates to improvements in the apparatus described in Specification No. 6283, A.D. 1894, for the step-by-step rolling of tubes from hollow ingots by segmental rolls or swages mounted in a housing reciprocated along the length of the tube. The present invention relates to the feed motion and the removal of the rolled tube from the mandrel. The feed-screw I, carrying the mandrel N, is carried by a saddle K, intermittently moved along a bed C by a motor cylinder M. The screw is intermittently rotated by a sleeve A rocked by a rod D from a shaft F, which may be rocked as described in Specification No. 9917, A.D. 1897, or by other suitable means. The nut of the screw is held against longitudinal movement in the saddle, the tube 0 being thus intermittently advanced and rotated between the reciprocating rolls or dies V<2>, V<3>. The screw has an internally-screwed sleeve P<3>, held by a cottar l, which also secures the mandrel. The sleeve screws over a second sleeve S, with a collar S' to ensure displacement of the metal in the right direction. After most of the tube has been rolled, a collar S<1> on the sleeve S comes in contact with a bracket W, holding the sleeve against advancement and rotation, and thus causing the mandrel to be advanced through the sleeve so that the remainder of the tube can be rolled without interference from the collar S'. The work can then be removed bv passing a yoke U, Fig. 5, over the mandrel between the tube and the bracket W, thus stripping off the tube when the saddle is drawn back by the motor cylinder M. During the withdrawal, a stationary rack B operates gearing B', A<4>, A<3> to reverse the screw and return it to its original position in the nut, a clutch A<1> being operated to connect the wheel A<3> to the screw. The wheel A<3> may be driven from the main shaft or a suitable motor. Fig. 4 shows a modified form of sleeve, in which the part P<3> is formed without the internal thread and has long slots L to accommodate the cottar l. The sleeve is frictionally held on the head of the screw I by a set-screw X, and slips over the head when the movement of the sleeve is arrested by a friction washer S<4> engaging the bracket. Elastic cushions may be arranged so that tho saddle is not held too rigidly on the bed.

The tube and coil are enclosed in metal tubes P, Q and a cap S attached to a supporting-bracket R. The coil is connected by vertical sleeves with wires carrying terminals, which may be directed towards either the front or the back of the instrument. The lower part of the coil may be wound thicker than the upper part, and surrounded by additional resistant wire wound on a longitudinally-corrugated paper tube. The glass tube C is supported on an adjusting- screw t, and is held forward by a spring in the lower metal tube P, which is slotted in front and carries a scale. The indicating-mark on the float is a line on a piece of paper F, secured in the bulb, in optical contact with the glass, by a transparent cement, such as Canada balsam, glycerine and gelatine, or one of the latter ; this causes the line to appear to extend across the whole width of the glass tube. The bulb may be made with small projections, or it and the depending weight may be surrounded by rubber rings, and cork or rubber rings or discs may be placed in the tube C, to prevent breakage of the float in transit. The stem a may be enlarged at its upper end, either gradually or by a - step, to extend the upper part of the scale. Or the float may be provided with a removable stem of unglazed porcelain, and the upper part of the tube filled with a staining-liquid, to enable the instrument to be used as a maximum indicator
