Patent GB-189807376-A (GB)
Title: Improvements in the Treatment of Ores containing Precious Metal, for the Recovery of the Precious Metal therefrom.
Inventor: WETHERED HENRY
Filed: 1898-03-26
Granted: 1899-02-18
Abstract: 7376. Wethered, H., [Gilmour, J. A., and Young, H. S.]. March 26. Gold; silver; amalgamating.-Ores, especially slimy ores, are treated with a cyanide solvent, with or without mercury, and are then treated with an amalgam or a mixture of amalgams. When treating for the extraction of gold, a mixture of zinc and copper amalgams is preferred, and if silver is being dealt with a mixture of lead and tin amalgams is found effective. The ore is first ground and charged with water into an agitator. Mercury is then added, and afterwards the cyanide, in solution or otherwise. Or the cyanide and mercury may be supplied together, or the former alone without the mercury. After the metal has been dissolved out, the amalgam, or a mixture as referred to above, is added. The ore may, if desired, be heated by steam during the amalgamating process. The charge is then run into a settler provided with a siphon cup and straining-bag, and treated in the ordinary way, or may be dealt with on concentrating-tables.

Title: Improvements in Detectors for Checking and Controlling Watchmen and Employees.
Inventor: DEMUTH JOHN ARTHUR
Filed: 1900-08-03
Granted: 1900-09-29
Abstract: 13,977. Demuth, J. A. Aug. 3. Tell-tales for checking watchmen. Clockwork 18, Fig. 3, drives a spur-wheel 20 carrying a pricker 21 and, through the spur-wheel, two other spur-wheels 26, 27 differing slightly as to their number of teeth and carrying dials having letters and numbers marked round their peripheries, as shown. The letters only appear successively through sight-holes in the casing of the apparatus, the numbers being for determining, when first setting the apparatus, which letter (as each is repeated several times) is under the sight-hole, so that is can be recognized in the subsequent checking operation. The watchman, at each visit, inserts the card, Fig. 6, at the bottom of the card carrier 35, Fig. 5, and then presses the carrier in, against the action of springs, by pushing the knob 41. The pin 21 punctures the card in the circle 49, which is divided for hours and tens of minutes, and so indicates the time of the visit. The card is forced off the pricker by a spring 22. The watchman then notes in the blank space 48, corresponding to the number of the visit, the combination of letters appearing at the sight-holes. The subsequent checking is effected by an apparatus nearly resembling that shown in Fig. 3. The card is torn along the line 50, and the upper part placed upon spikes on a wheel similar to 20 in a position corresponding to the first visit of the watchman. Wheels similar to 26, 27 are set in corresponding positions and then thrown into gear with the wheel 20. The punctuations on the part of the card 49 are then brought successively opposite a pointer, and the letters on dials similar to 26, 27 coming opposite two fixed pointers should correspond to those entered in the spaces 48 by the watchman. Time-checking apparatus for workmen. A rack is provided having slots to receive numbered cards, divided and marked according to the purpose required. The workmen who arrive in time take their cards from this rack, initial them in the proper place, and deposit them in a box having a sloping slide to keep them in regular order. Late workmen, the box having been removed, must use the pricking-apparatus already described, tickets as shown in Fig. 6 being given to them. On these they mark their working time as indicated by the holes pricked. Calculating-apparatus.-To verify the workman's calculation of the working time, the upper part of his ticket is secured to a rotary disc, normally held by a spring brake. A radial arm with two pointers works over this disc and over a concentric dial marked for hours, one of the pointers travelling over the card and the other over the dial graduations. Proper adjustment having been made, the brake is allowed to clamp the disc, and the angular distance between the punctures is measured by one pointer, the other showing the corresponding time.

Abstract: 15,344. Goreham, W. F. Aug. 29. Separating or sorting cements &c.-Relates to apparatus for separating the finer particles from cement or other material. Fig. 1 shows a small apparatus adapted for testing purposes. The material is placed in the glass receptacle a, at the bottom of which is a small metal cone d. The vessel a is pressed against a rubber ring b<2> and a current of compressed air is passed into it from the serrated lower end of a tube e. The fine particles carried off descend the branch b<1> of the tube b, and are deposited in the expansion chamber c. Fig. 6 is a transverse sectional view of an apparatus for use on a larger scale. The chamber a is inclined from the feed to the tail end, and is provided with helical feed and discharge apparatus. The tube b conveys air laden with fine particles to an expansion chamber not shown. Compressed air is supplied to the chamber c through an inlet i, and issues through slits &c. d into the material, which is kept in a state of agitation by stirrers h. Guards or baffles k are secured to the walls of the chamber a, and windows are provided for purposes of inspection.

Title: Improvements in the Method of and Machinery for the Carding of Fibrous Materials and Manufacture of Yarn.
Inventor: SPOAK ALFRED
Filed: 1900-09-12
Granted: 1901-05-25
Abstract: 16,219. Speak, A., and Sedgwick, J. H. Sept. 12. Combined carding and spinning machines; processes.-The material is fed into the machine through a number of feedrollers A-B, of gradually-increasing diameter, and arranged so that dust and impurities may fall from the material into a receptacle on the space beneath. The swift D is rotated slower than usual and in the direction opposite to that in which the teeth thereon are set. The workers and clearers C-C<4> and E-E<4> are arranged alternately round the swift and are of gradually-increasing diameter as shown, or are otherwise so mounted and driven that their surface speeds are progressively increased from the feed to the doffer end of the carding-engine. The material is removed from the swift and laid on the doffer G by means of a roller F having radial teeth. The fibres may be removed from the doffer in a continuous fleece or, when a ring doffer is used, in a number of slivers, which are passed through a combined drawing and twisting apparatus K, K<1> before being wound on to the bobbins T. In the combined drawing and twisting-apparatus, a pair of drawing-rollers J, Fig. 5, are carried by one rotating pulley K, with their axes at right-angles to that of the pulley, and toothed wheels on the axles of the rollers engage with teeth on the face of the second pulley K<1>. The pulleys are driven independently, and at speeds which may be varied, so that the ratio of the amount of twist to the draught may be regulated as desired. The different parts are driven by belt &c. geariug from the main shaft S. When yarn of great uniformity is required, the bobbins T of lightlytwisted fibres may be mounted on a suitable creel and passed through a carding-machine such as that described in Specification No. 17,169, A.D. 1898.
