Title: Improvements in Induction Valves for Motive Engines and other purposes, and in Gearing to Actuate the same.
Inventor: GREEN WILLARD REED
Filed: 1898-12-20
Granted: 1899-01-21
Abstract: 26,844. Green, W. R. Dec. 20. Valves and valve gear.-Relates to lift or beat induction valves and valve gear for steam engines, air compressors, and the like. Two valves 3 and 5 of unequal area are mounted on the same stem with a piston 12, above which a partial vacuum is maintained. The space 4 between the valves is capable of being put in communication, through a passage 37 governed by a tubular slide 7, with the pressure space 6 above the valves. When the passage 37 is open the valves are just kept closed by the resultant pressures, but at other times they are kept closed forcibly. The valves are opened by means of a gyratory lever turning about a ball fulcrum 20 and operated by screw gearing and an adjustable crank. This lever in lifting acts first on the tubular stem of the slide 7, so as to cause the slide to open the passage 37 and so reduce the nett pressure on the valves, and then raises the valves against the reduced pressure. The movement of the lifting-lever gives the valves a slight rotatory movement relatively to their seats.

Title: Improvements in Machines for Mercerising Hanks of Yarn.
Inventor: COPLEY JAMES FREDERICK
Filed: 1899-05-25
Granted: 1900-03-31
Abstract: 10,936. Copley, J. F., Marshall, P. S., and Heaton, R. May 25. Yarns, mercerizing.-The hanks are carried by a pair of chains successively through the mercerizing and washing tanks a, b, and are pressed between the rollers i, j in passing from one tank to the other. The lower portions of the chains are tight, while the upper portions are slack to allow of the removal and application of the hanks. The hanks m are placed on rods which are carried by adjustable hooks k<2>, k<3> mounted on rods g<1> connecting the chains, and when passing round the wheels c are not stretched beyond their normal length, but between the wheels c and e, and while passing round the wheels e, the hanks are stretched, in the first case owing to the straightening of the chains and in the second because of the hanks passing over loose guide-rods n which cause them to assume the curvature taken by the chains. One of each pair of hank-carrying rods is fitted with a star-wheel p, which gears with a fixed rack p<1>, p<2> within each tank, so that the hanks are moved on their carrying-rollers during the mercerizing process. Several sets of wheels similar to c may be interposed between the wheels c and the pressing-rollers, in order that the hanks may be stretched and released several times in succession. Instead of allowing the hanks m to assume positions corresponding to the chords of portions of the circumference of the chain-wheels c, an expansible link, as shown in Fig. 4, may be inserted in each chain at intervals. The expansible link is in two parts t, s, each of which is pivoted to an ordinary link g, while the part t carries a pin t<1>, which projects through slots in the part s and is connected by springs u to pins u<1> on an adjacent ordinary link. In this case the second set of chain-wheels e may be driven at a greater speed than the first set c, and the tank a is fitted with guide-rods similar to n.

Granted: 1900-03-10
Abstract: 24,107. Allis, T. V. Dec. 4. Rolling. -A pack of two or more metal strips is prepared for rolling by arranging the ends in step form and temporarily securing them so that they may be rolled to the desired thickness at one pass. A gas furnace particularly suitable for heating the pack has a brick-lined chamber, Fig. 3, the roof of which is formed by bricks 6 with T-slots engaging ribs on the beams 8. The bricks are thus easily removable and interchangeable. The packs are placed in channel ways 13, 14, 15 supported above the floor. Gas and air are supplied by pipes 24, 25 through branches 27, 29 in the floor, the branches opening into pockets 31. The ends of the chamber have apertures opposite each channel way, and may have a casing or guideway placed opposite either pack to maintain its temperature while fed to the rolls. The preferred form of guideway is shown in Figs. 15 and 17, and consists of two parts 45, 46 with flanges to cover the chamber apertures not in use. The pack is guided vertically by ribs 53, 54, and horizontally by plates, Fig. 17, which can be closed in by a handle 63 on a rock-shaft 55 having pins engaging the plates which are maintained parallel to each other by links 60. Fingers 67, carried by pins 69, 70 on the plates, serve to guide the front end of the pack, being pressed inwards by a weighted bell crank 77 acting on arms 72 on the pins 69, 70. The rolls are of an ordinary type, and may be heated by gas before being used. A travelling crane is provided to pick up the rolls and replace them by another set so that repairs may be executed without stopping the plant. The furnace is mounted on wheels running on a track 92, with branches and a turntable so that one of a number of furnaces may be brought up to the rolls. Whilst in front of the rolls the furnace rests on a trolley 93 on which it can be moved laterally. The furnace may be used for single strips or bars.
Patent GB-189924392-A (GB)
Title: Improvements in connection with the Manufacture of Gas-ignition Pills.
Inventor: MARTINI ADOLF
Filed: 1899-12-07
Granted: 1900-11-03
Abstract: 24,392. Martini, A. Dec. 7. Lighting gas.-In the manufacture of catalytic igniters from meerschaum, a rare earth, and a metal of the platinum group, the meerschaum pellet is first treated with hydrochloric or other acid and water, or, in some cases, with alkalies, to remove the soluble hygroscopic parts. The resulting porcus substance, kept in a wet state at a low temperature to prevent the porosity from being destroyed by slagging, is impregnated with a solution of a salt of one of the rare earths, preferably absolutely-pure thorium nitrate, which is reduced to oxide very slowly at a low or moderate temperature. After lixiviation with hot water, the pellet is impregnated with a solution of platinum chloride, which is reduced by heat or gas, a low temperature being maintained if water gas be used for this purpose. Repeated cleansing with water and acids is not generally necessary, but steam, sulphuric acid, ether, or ammonia may, in some cases, be used. The difficulty of obtaining the thorium salt in an absolutely-pure condition may be overcome by only utilizing the thorium salt to assist the deposition at a low temperature of the metallic platinum in a finely-divided state in the pores of the pellet, the thorium salt, which, owing to the low temperature employed, has remained soluble, being subsequently washed out.
