Patent GB-190106173-A (GB)
Title: Improvements in or relating to Buffing Rolls for Boots, Shoes and the like.
Inventor: WEBSTER HAROLD ARTHUR
Filed: 1901-03-23
Granted: 1901-11-16
Abstract: 6173. Webster, H. A. Aug. 23, A.D. 1900, [date applied for under Sec. 103 of.Patents &c. Act, A.D. 1883]. Surfacing and polishing.-In order to produce rotary cushioned rolls for abrading or burnishing boots, shoes, and other articles, which rolls shall be sufficiently firm to do the required work and yet sufficiently yielding to accommodate themselves to curved surfaces and avoid injurious pressure on the work, the hub is formed in two parts 1, 2 of which the one part 2 is so connected by screw threads or friction to a projection 3 on the other part 1 that the length of the roll may be adjusted, and the outer end of each part terminates in flanges 6, 7 which are respectively secured to the rotary spindle or shaft by set-screws 4, 5. Around the hub, two cushion sections 8, adapted to be distended by centrifugal force, and to support a tubular working cover 9 of sandpaper or other material, are formed by nesting dished or conical rings of leather or other tough and flexible material. The portions of the end discs projecting beyond the flanges 6, 7 allow the roll to operate in corners, as between the shank bottom and the breast of the heel, while opposite the V-shaped space between the two cushion sections 8, a projecting strip 10 of cloth or cord is fastened to the inside of the cover 9 to bear against the inner ends of the cushion sections, and prevent the longitudinal displacement of the cover. To reinforce the cover at this point, a felt or other centrifugally-distensible cushion 11 is placed loosely within the strip 10. The cover is placed in position by first moving it on to one part of the hub, and its cushion section in position on the shaft, and then inserting the other part of the hub and its cushion section into the cover, and securing it to its companion. When the apparatus is in motion, the tendency of the strip 10 and the discs to move outwards imparts the necessary firmness and elasticity to the working cover 9. The discs can be replaced on either portion of the hub 1, 2 by a continuous band wound helically about the hub and inclined outwardly, similarly to the discs.

Title: Improvements in Mordanting Wool.
Inventor: IMRAY OLIVER
Filed: 1902-07-31
Granted: 1903-02-05
Abstract: 16,980. Imray, O., [Jung, E.]. July 31. Dyeing.-Consists in mordanting wool by treating it, at a temperature not exceeding 65‹ C., either with chromium sulphocyanide (normal or feebly-basic) or with a double compound of chromium sulphocyanide, e.g., that obtained by dissolving chromium hydroxide in ammonium sulphocyanide or that obtained by introducing chromate or bichromate of ammonium, potassium, or sodium into fused ammonium sulphocyanide. The process is preferably carried on in presence of a soluble chromate, and small quantities of a nitrite, a soluble salt of copper, and a free acid may be added. The nitrite or copper salt promotes the subsequent development of the lakes, and fixes the chromium compounds. When a copper salt is used, the process is well suited for dyeing Campeachy black.

Title: Improvements in and relating to Outlets or Exits for Inclined Storage Compartments or Floors.
Inventor: LEETHAM RICHARD EDMUND
Filed: 1903-05-20
Granted: 1904-04-21
Abstract: 11,463. Leetham, R. E. May 20. Shoots.-Relates to outlets or exits for inclined storage compartments cr floors, described in Specifications Nos. 20,682 and 23,284, A.D. 1900, and used for the storage of grain &c., in sacks, goods in bales, &c., and consists of means for delivering such sacks &c. one by one at any desired intervals. At the outlet end of the inclined floor a is pivoted a trap b, the end c of which, in the position shown, projects above the level of the floor and forms a stop, agaiust which rests the lowest package d in the store. When the delivery of a package is required, the projection c is withdrawn, the lower end of the trap being at the same time raised. The package then moves downwards, and, on passing the pivot p, depresses the lower end of the trap, thus causing the part c to rise and block the next passage. The apparatus remains in this position until the trap is again raised, either by hand, or automatically after a predetermined interval. Means for the automatic operation of the trap are shown in Fig. 5 in connection with a somewhat modified trap. The trap b is, as before, turned into its blocking position by the passage of the package, but is automatically shifted to its other position by its connection with a lever m, the lower end of which is depressed by the package in the course of its progress down the shoot. In a modification, the actual stop consists of a pivoted plate, which is moved between a vertical "stop" position and a "pass" position, flush with the floor, by means of a trap similar to that shown in Fig. 1. In another modification, the trap consists of a pivoted plate, which is moved through half a turn by the passage of each sack, and always in the same direction. These modified forms of trap embody the same principle as that shown in Fig. 1, but are not claimed.

Title: An Improved Apparatus for the Production of Acetylene Gas.
Inventor: DANANCHE RAOUL DE
Filed: 1903-08-14
Granted: 1903-09-17
Abstract: 17,648. Dananche, R. de. Aug. 14. Acetylene, making automatically. The carbide holder T, which is connected with the concentric tubes O, I, by means of a screwed ring, is placed in a vessel of water, and the tap G is connected to the gas burner or burners, either directly by means of a hollow stem, or by an india-rubber tube. The water enters the tube O by the hole A, but does not rise to the hole K in the inner tube I which is some distance above the hole A until the tap G has been opened to allow the contained air to escape, since the tube O is not in direct communication with the carbide chamber. When the gas supply is no longer required, the tap G is closed, and the gas, generated by the water as it falls drop by drop, exerts a pressure inside the tubes O, I, causing the water to fall again by the level of the hole K, thus stopping further generation of gas. A gas holder may be added to accumulate a certain reserve of gas without adding anything to the automatic action of the apparatus.

Title: Improvements in the Manufacture and Production of Sulphur Colouring Matters and Intermediate Products therefor.
Inventor: JOHNSON JAMES YATE
Filed: 1903-11-16
Granted: 1904-10-27
Abstract: 24,930. Johnson, J. Y., [Badische Anilin & Soda Fabrik]. Nov. 16. Amines; dyes, artificial.-(1) Indophenols result when o-o-dichlor-p-phenylene-diamine (2.6.1.4) is oxidized with a phenol. In an example, an aqueous solution of the p-diamine, hydrochloric acid, and ordinary phenol are mixed, and the whole cooled to 0‹ C. with addition of ice. While stirring, an aqueous solution of bichromate is added, and on further addition of an aqueous solution of sodium acetate the indophenol is filtered off, washed, pressed, and dried. It is only gradually decomposed after long standing with 30 per cent. acetic acid. (2) Diphenylamines result on reducing the indophenols say with aqueous sodium sulphide. The crystals are soluble in caustic soda, the solution turning reddish blue in air with gradual precipitation of the indophenol. (3) The indophenols yield sulphurized dye-stuffs when treated with sulphur and alkaline sulphide. In an example, an aqueous solution of crystallized sodium sulphide is mixed with the indophenol, and sulphur is added. The whole is evaporated until the temperature rises to 120‹ C., when a reflux condenser is fitted and the vessel is closed. When the indophenol has almost or entirely disappeared with continued heating, the mass is extracted with boiling water, the solution is filtered, and air is passed through the filtrate. The dye-stuff separates as a dark powder, which is filtered off, pressed, and dried. It yields a blue solution with concentrated sulphuric acid, and a violet one with a small quantity of sodium sulphide. With excess of the latter it readily undergoes reduction to the leuco compound, like the related indophenols. These sulphide solutions dye unmordanted cotton greenish-gray to bluish-gray shades, rapidly turning deep violet on exposure to air. A similar dye-stuff is obtained by using the corresponding diphenylamine in place of the indophenol, or by heating either of these bodies with alkali polysulphide to a higher temperature, say 160‹ C. The raw melt may be used directly, or the dye-stuff extracted as before.
