Title: Manufacture of Sulpho-acids of Aposafranines.
Inventor: IMRAY JOHN
Filed: 1898-07-07
Granted: 1899-06-24
Abstract: 14,962. Imray, J., [Actiengesellschaft f³r Anilin Fabrikation]. July 7. Dyes, artificial.-Sulphonic acids of the aposaffranines in which formulµ R R, R2 represent a substituted or unsubstituted radicle of the aliphatic or aromatic series, are produced by beating the said aposaffranines with a neutral or acid sulphite on a water bath. Examples are given in which monosulphonic acids are thus prepared from the aposaffranine and from neutral-blue, and a disulphonic acid from the isorosinduline sulphonic acid The new products yield on wool in an acid bath similar shades to the unsulphonated substances. The sulphonic group is probably attached in the para position to the azine nitrogen, and is easily removed by the action of alkalies or primary amines, saffranones and saffranines being thus formed.

Patent GB-189902400-A (GB)
Title: Improvements in Cocks or Faucets.
Inventor: LORRAIN JAMES GRIEVE
Filed: 1899-02-02
Granted: 1899-03-11
Abstract: 2400. Lorrain, J. G., [Perry, I. D., and Weir, J. B.]. Feb. 2. Lift valves.-Relates to means for preventing leakage by ejector action, and also for cushioning. For the former purpose, the outlet J is curved upwards so as to be intersected by the spindle. Where the spindle passes through it, it is constricted, its section, looking from the bib, being shown in Fig. 3. The stream is thus divided, and forms an eddy which prevents leakage past the spindle. The web which forms the constriction may extend entirely across the passage J, which is thus divided into two before the spindle is reached. To effect cushioning, a chamber E<2> is formed in the casing immediately above the valve and has a head or disc H<3> on the spindle working in it. The liquid, which enters the chamber when the valve is depressed, escapes slowly past the spindle through an opening J<3>.
Patent GB-189905633-A (GB)
Title: Improvements in Speed Indicators for Velocipedes and other Vehicles.
Inventor: WINTER JOHN BRADBURY
Filed: 1899-03-15
Granted: 1900-02-24
Abstract: 5633. Winter, J. B. March 15. Speed indicators.-Relates to a speed indicator for velocipedes and other vehicles, Figs. 1 and 3 showing partial front and side elevations respectively. The frame a has a spindle on which rocks an inner frame b carrying a second spindle y provided with a clock spring. The index p<1> is fixed on a short spindle p journalled in the frame a,and is rotated by means of an arm g moved by a pin r fixed to a toothed wheel w on a second short spindle q carried by the frame b. The spring - controlled pivoted racks h, h' normally retain the index and the pin r in the zero positions, and hold the frame b against the stop a, as shown in Fig. 1. The wheel i, driven from the hub of the vehicles, initially rotates the wheel k and spindle y to coil up the clock spring. This spindle turns the arm l into contact with the pivoted lever m, which rotates the part n round the spindle d until it takes under the pivoted catch o. Normally the part n is spring- pressed against the wheel w to act as a brake, but when engaged with the catch o the spring operates against the action of the spring h<2> to turn the frame b round the pivot d, thus disengaging the wheels i, k and engaging i, w. The clock spring is thereby free to rotate the spindle y in the reverse direction, and so to move, through a pinion, an escapement which, after a determined time, allows a pin to lift the lever o, and thus causes the spring on the spindle d to return the brake n into contact with the wheel w. The frame b is then returned to its initial position by the spring h, h<2> until the wheels i, k again gear together. The index is retained in any position by a spring-controlled brake j, of which one arm j is adapted to be operated by the arm l.

Granted: 1899-09-23
Abstract: 9349. Ostmann, C. May 3. Percussive hand tools.-Relates to an electromagnetic hammer, for use in stopping teeth, in which the working parts are enclosed in a tube which serves as a handle. A current is passed through a coil d surrounding two soft iron cylinders x, z. The current enters at a, and passes through a spiral spring n, at the end of which is a platinum strip o in contact with a platinum pin p on the cylinder z, then through a spiral s, connected with the metal tube, to w, where one end of the coil d is soldered, and through the coil cl to k. A switch (not shown), closed by a sliding plate, is used to start the instrument. The cylinder z is suspended by the spring s, and, when the circuit is closed, it moves forward and strikes on the end e, driving the cylinder x forward against a spring f. At the same time the current is broken at the contacts p, o, and the spring s again closes the circuit. The force of the blows can be regulated by adjusting the distance between the cylinders, or by a rheostat.

During the cutting operation, the lengths of paper &c. are supported by holders K, Fig. 4. The twisted paper &c. G passes from a box H, Fig. 1, round guide-pulleys i<1>, i mounted upon, or within, a box containing shellac or other suitable material ; this box is attached to a divided nut F, which travels along a screw E, rotated by means of a pulley D ; the nut F is prevented from rotating by a strap frame F<1>, formed of two parts hinged together at F<4>, and encircling at E<3> a stationary rod E'. After leaving the shellac &c., the paper or other cord passes through a sponge i<2>, and then through an eyelet G', on the frame F<1>, which guides the cord into notches formed in a series of plates B<1> fitted radially within recesses in the reel B. The reel is rotated by means of a handle C. When the reel has been filled, it is removed from its bearings, and one of its journals is placed within a cylindrical bearing U carried by a block O<1>, Fig. 2, which slides upon a bar P. The bearing O is concentric with the ring N, carrying the cutters, and, when the block O<1> is pushed along the bar P, the lengths of cord between the plates B' are severed. Before being cut, the lengths of cord are clamped between the jaws K of the holders, Fig. 4, such jaws being connected by spring arms l<1> and connected by a catch m when in the closed position. In placing the holders in position, they are guided by blades B<2> which are fitted to the reel B, and engage with bifurcated lugs S, on the lower jaws.
