Abstract: 1991. Schofield, H., and Macfarlane, O. P. Jan. 25. Water-circulation, promoting.-One or more connecting-pipes are arranged to receive water and steam ascending Galloway and like tubes and to discharge them through a suitable outlet in any desired direction. The apparatus may be combined with a circulation tube and settling-chamber of the kind described in Specification No. 26,286, A.D. 1897. In the arrangement shown in Fig. 2, the connecting-tube a is formed with a discharge branch having a horizontally-projecting nozzle b. The discharge pipe may be continued to the bottom of the boiler, and a steam outlet may be provided at the middle of the connecting-pipe. In a modification, two curved pipes leading from the tops of the Galloway tubes are united at their ends to form a double discharge nozzle. In another arrangement, shown in Fig. 5, the two forms are combined, the steam collecting in the connecting-pipe a being led to a nozzle c<1>, shown in dotted lines, within the discharge portion b of two bent pipes, the ends of which project into the Galloway tubes as shown in dotted lines at b<2>. When conbined with the circulation and settling apparatus described in the Specification quoted above, which apparatus is also described independently in the Provisional Specification of this case, the discharge from the tube a is delivered through a nozzle within the delivery end of a circulation pipe extending from the bottom of the boiler and connected with a mud box or settling- chamber. The turned-down ends of the tube a, instead of closing the Galloway tubes, may be smaller in diameter and pass through them to the bottom of the boiler. In some cases, also, the lower ends of the Galloway tubes may be partially closed by a guide or deflector.

Rolling.-A rolling - mill for the treatment of worn steel rails comprises breaking-down rolls e, rollers l, and travelling ways m, which transfer the rail to other rollers c, and roughing and finishing rolls d. The rails are charged into furnaces a from the outside, and a rail is discharged from either furnace through the corresponding set of rolls e, which apply pressure to the head and foot and upset the web. The rolls e are provided with travelling or adjustable guides to conduct the rail to any desired part of the rolls. The rail is then carried forward by the driven rollers l, and moved laterally on ways m by chain and sprocket gearing o, the chain having dogs p to engage the foot. The rollers l can be driven in either direction to suit the furnace being used, and the chain gearing can be stopped and started when desired. The framework of the ways m carries a roller stop r which tips over the rail when opposite one of the passes of the rolls d, and allows it to rest on the driven rollers c. At the same time, it is disengaged from the dog p by the latter passing over the sprocket. The rail is then fed through the roughing and finishing rolls which impart to it its original section, allowing the original fishplates to be used. The framework of the ways is carried on rollers n, and is adjustable by rack and pinion so that the tipping of the rail takes place opposite any desired one of the passes in the rolls d. The arrangement of the mill allows the rolls e, d to be continuously revolved, whichever furnace is used.

Patent GB-190012575-A (GB)
Title: Improvements in the Methods and Apparatus for Superheating Steam.
Inventor: WATKINSON WILLIAM HENRY
Filed: 1900-07-12
Granted: 1901-05-18
Abstract: 12,575. Watkinson, W. H. July 12. Superheaters, steam; steam generation by heated liquids.-According to the arrangement shown in Fig. 2 (Sheet 1) as applied to a water-tube boiler, products of combustion are taken directly from the furnace and passed through a chamber H containing a superheating-coil a of fine tubing, and returned to the furnace by a steam-jet blower c. The supply of heating-gases may be controlled by regulating the supply of steam to the blower, by adjusting a damper at E, or by admitting a regulated supply of air at d. The coil a is made up of sections connected in parallel to a divided header tube shown by dotted lines at b. Baffles compel the heating-gases to pass through the narrow spaces between the tubes of the coil. A similar arrangement is shown in the Specification applied to a Lancashire boiler. In this case the heating- gases are taken from, and returned to, the flues at the back of the boiler. Fig. 1 (Sheet 3) shows an analogous arrangement applied to a locomotive. The superheater a is enclosed in a chamber H at the side of the firebox, with which it communicates at G. The heating-gases are passed on through a feedwater-heater at M, and are finally discharged into the smoke-box. In this and other arrangements the surplus heat of the furnace gases may be utilized to heat the air supply to the furnace. Fig. 1 (Sheet 4) shows a superheater a heated by an independent furnace, the temperature of the fire-gases being equalized by heat-absorbing baffles P. Fig. 1 (Sheet 5) shows a superheater combined with a gas-producer and heated by the combustion of the gas produced. The superheater tubes a are shown enveloping the producer, but they may be arranged in a chamber above it. Fig. 1 (Sheet 6) shows an arrangement in which a heated liquid is caused to convey the heat from the furnace gases to the steam, the surplus heat of this liquid being utilized to heat the water in the boiler, the circulation in which is thereby improved. The heating-liquid is contained in a circulation tube forming a closed circuit and comprising three coils, one U in the combustion chamber, another a in the superheater, and a third w in the water space of the boiler. The liquid is heated in the coil U, imparts heat to the steam by means of the coil a, and gives up its surplus heat to the water in the boiler by means of the coil w. By raising the disc x the steam may be passed through the superheater without traversing the spaces between the tubes of the coil, and the degree of superheating may thus be regulated.

Title: Improvements in Sighting Devices for Guns.
Inventor: GRUBB HOWARD
Filed: 1900-12-05
Granted: 1902-02-05
Abstract: 22,127. Grubb, Sir H., Dawson, A. T., and Buckham, G. T. Dec. 5. Telescopes.-Consists of improvements upon the sighting apparatus for ordnance described in Specification No. 12,108, A.D. 1900. Fig. 1 shows a vertical longitudinal section, and Fig. 2 an end view, of one form of the invention. A horizontal tube c is provided at its front end with a glass sight-piece d, covered with some opaque material, through which a design, such as the cross e, is cut. An object-glass f renders the luminous rays from the sight e parallel to one another, and a piece of thick glass a, silvered at its lower back part and inclined at an angle of 45‹, receives the image and reflects it upon the front surface s<1> of the glass, whence it is reflected back to the eye of the gunner. The distant target, when viewed by the gunner, will hence be seen with a phantom image of the sight e superposed thereon. The sight e must be strongly illuminated, and, to increase the briliiancy of the reflected image while reducing that of the target, a neutral-tinted glass h may be arranged near to, but not in actual contact with, the glass surface s', or, instead of the glass h, the surface s' may have a semi-transparent reflecting coating deposited thereon. In the modification shown in Fig. 3, the upper part of the glass a consists of two prisms u, v of crown glass. With this arrangement the prism u may be made separate from the lower prism k, which is then made of flint glass and without the silvered reflecting surface s<1>. In the modification shown in Fig. 4, the luminous image of the sight is seen direct, while the image of the target is seen reflected from the prism m upon the semi-transparent reflecting surface a<1>. Instead of rendering the luminous rays proceeding from the sight parallel by refraction through the convex lens f, they may be rendered parallel by reflection from a concave reflecting surface, as shown in Fig. 5. In this arrangement, both the target and the image of the sight are seen direct, the glass a having a semi-transparent reflecting surface a<3>, and the illuminating light entering the tube b through the opening d*, and being reflected upon the surface a<3> by the prism d', or by an ordinary mirror.
