Patent GB-189903326-A (GB)
Title: An Improved Process of Amalgamating and Concentrating Ores.
Inventor: BYRD ANTHONY ALBERT AUGUSTUS
Filed: 1899-02-14
Granted: 1900-02-10
Abstract: 3326. Byrd, A. A. A. Feb. 14. Amalgamating. - For obtaining gold and other precious metals, the following process and apparatus are employed. Air is forced by a pump A into a reservoir B, from which it passes to a coil E heated by a stove D. The hot air passes by a tube G to a retort F containing mercury H. The temperature within the retort is maintained at not less than 300‹ C., as shown by the thermometer I. The hot mercury vapour given off passes up the tube L to two perforated pipes M, N, and melts the pulp which enters the chamber 0 by a funnel P having a small central opening. The pulp flows downwards and outwards over an amalgamated copper cone Q, and then inwards over a second amalgamated copper funnel R. The amalgam adhering to the copper plates is removed at intervals through a manhole Y. The superfluous mercury and tailings pass by a tube 8, at the bottom of which is a turbine plate K, to a vessel T called a "divider," in which a layer of mercury V is maintained. The mercury is rotated by the incoming material and by the turbine plate. The heavy concentrates are removed by one siphon U, and the valueless tailings by another W at a higher level. The mercury, together with any precious metals, may be drawn off at intervals by the valve X.

Granted: 1900-05-05
Abstract: 24,227. Lake, H. H., [Huestis, F. W.]. Dec. 5. Treads; footways. - Slits are cut in a bed-plate a of sheet steel or other bard material, as shown in Figs. 1, 6, and 11 ; the tongues a<1> are turned up at right-angles, and strips b of lead or other non-slipping material are secured between the tongues.

Patent GB-189925640-A (GB)
Title: Improved Vacuum Evaporating Apparatus for Separating Salt from Solutions, especially from Brine.
Inventor: VIS GERHARD NICOLAAS
Filed: 1899-12-28
Granted: 1900-12-28
Abstract: 25,640. Vis, G. N. Dec. 28. Evaporating brine; vacuum apparatus.-Relates to the vacuum apparatus for evaporating brine described in Specification No. 16,738, A.D. 1899. In the apparatus described in that Specification, the brine is prevented from rising too high in the evaporators A by means of a pipe the lower end of which dips into the brine reservoir D and the upper end of which opens into the upper part of the evaporator A so that, when an excessive quantity of liquid passes from the reservoir D into the evaporator A, the lower end of the pipe becomes uncovered thereby, admitting air to the evaporator and causing the l i q u i d level to be lowered. In practice, i t is found that these pipes become incrusted with salt, and this invention consists in causing the stoping end of this pipe l to dip into a small quantity of a liquid, such as glycerine, water, oil, or mercury, which will not form incrustations. A vessel l<2> provided with baffle-plates l<3> prevents the liquid from passing over into the boiler.
Patent GB-190003934-A (GB)
Title: A New or Improved Method of and Means for Regulating the Degree of Humidity of the Air in Incubators.
Inventor: SUTCLIFFE JOHN HENRY
Filed: 1900-03-01
Granted: 1901-02-09
Abstract: 3934. Sutcliffe, J. H. March 1. Incubators.-Relates to means for regulating the degree of humidity in the air in incubators. The incubator is fitted with an egg tray A<1>, water tray B, hot-water tank C, and heating-lamp D as is customary. The egg chamber A is ventilated through a bent pipe J, the upper outer end of which is closed by a damper K suspended from a lever K<1> pivoted at K<2>. The opposite end of the lever K' is connected by a rod K<3> to an arm secured to a rock shaft L supported in a frame L<1>. A piece of catgut or similar material susceptible to moisture M is coiled round the shaft L, and by its contraction and expansion operates the damper K, to prevent an undue current of air through the egg chamber when the air is not sufficiently humid, and to allow a strong current through when there is excess of moisture. The Specification describes modifications in the arrangement of the catgut M and in the form and arrangement of the outlet valve and passages. The valve may be applied to the air inlets, instead of to the air outlets.

Inventor: FEYERABENDT GUSTAV
Filed: 1901-07-30
Granted: 1901-10-19
Abstract: 15,402. Feyerabendt, G. July 30. Wood, fireproofing, preserving, &c.-Relates to a process of treating wood by heating it in a solution of sodium aluminate to which alumina has been added to prevent alkaline reaction. The temperature of the solution is about 270‹ to 300‹ F. The aluminate converts gums and resins in the wood into soaps. Wood treated in this way is hardened and non-inflammable. The alumina on the fibres acts as a mordant, and fixes dyes applied to colour the wood.

Abstract: 17,320. Corbin, P. E. C. March 25, [date applied for under Sec. 103 of Patents &c. Act, A.D. 1883]. Bromates; chlorates; iodates; perchlorates.- These or like compounds are produced by electrolysis of chloride, chlorate, or like solutions, containing a small quantity of chromic 'acid, which is kept in the state of bichromate by adding small quantities of a dilute acid, preferably hydrochloric, hydrobromic, or hydriodic acid, to the solution, so that it is never alkaline. The chromic acid remains unaltered, chlorine is not evolved, and the process is efficient as regards the current required. A warm solution of sodium or potassium chloride may be electrolysed, with additions of the chloride, so far that chlorate crystallizes out from the solution when this is cooled, without concentration ; the residual solution is returned to the electrolytic apparatus. Cathodes of carbon, iron, copper, or brass may be used, and the apparatus may be made of any desired material.

Abstract: 11,450. Schofield, E. H., and Cole, L. C. May 19. Extracts.-Relates to apparatus for obtaining extracts of coffee and other substances, in which the substance treated is caused to pass through the liquid in a direction towards the liquid inlet and away from the liquid outlet in a series of containers, to which a combined progressive and rotary movement is imparted. The apparatus comprises an elongated cylinder 1, heated by a hot-water or steam jacket 2, and provided at one end with an inlet 5 for inserting the cartridges or containers and at the other end with an outlet 1<a> for withdrawing them one by one. The containers consist each of a cylindrical body 6 and two perforated ends 7, 8, and are provided with lugs 21 and teeth 24 for engaging with corresponding teeth and lugs on the adjacent containers. Motion is imparted to the containers by a follower 12, carried by a shaft 13 provided with an elongated nut or sleeve 15, into which enters a screw 17 driven from a countershaft 25. By means of a spiral groove engaging with a fixed pin, the sleeve 15 is rotated as it is moved backwards and forwards. The countershaft 25 is driven by reversible friction gearing, consisting of a pair of friction cones 28, 29 movable longitudinally on the shaft so that one or the other engages a driving-cone 31. Assuming that the parts are in their inoperative position, as shown, and a fresh container has been inserted, the cone 29 is thrown into engagement with the cone 31 by raising a lever 33 connected by a link with the shifting-lever 37. When the forward movement is completed, a tappet 48 rocks a three-armed lever 41, 42,43,connected through toggle mechanism with the shifting-lever 37, and reverses the movement. On the completion of the backward movement, a second tappet 49 throws the mechanism out of gear, and another container is inserted into the machine. Floats are placed on the surface of the liquid in the inlet 5 so as to prevent the loss of aroma.
