Granted: 1899-03-11
Abstract: 1089. Wise, W. L., [Illinois Reduction Co.]. Jan. 17. Drawings to Specification. Metals, extracting.-Relates to the treatment of metallic ores, particu'arly those of copper. The ore is crushed, screened, and charged into a horizontal rotating digester, in which it is mixed with an oxidizing-agent, preferably manganese dioxide, and with an excess of sulphuric acid. The digester is slowly rotated, and hot air at 40-80 lbs. pressure is injected through the hollow trunnions. The process is complete in from 4 to 16 hours, when the solution, principally consisting of metallic sulphates, is withdrawn from the residue. The latter is washed, and the washings added to the sulphate solution. The whole solution, after standing to settle, is then passed over copper turnings, whereby the silver is deposited. The solution is afterwards electrolysed to separate the copper. Should the tailings contain gold, they are returned to the digester and treated with hydrochloric acid and manganese dioxide. The resulting solution is afterwards treated with ferrous sulphate or metallic zinc to precipitate the gold.

Title: Improvements in the Manufacture of Saccharine.
Filed: 1899-09-29
Granted: 1900-01-13
Abstract: 19,629. Lake, H. H., [Chemical Works formerly Sandoz]. Sept. 29. Saccharin.- Saccharin is produced from dry o-sulphamidobenzoic acid or its salts by the action thereon of dehydrating-agents, such as chlorosulphonic acid, sulphuric acid of 66‹ BÚ., sulphuricacid monohydrate, or fuming sulphuric acid. For example, o-sulphamidobenzoic acid is stirred into fuming sulphuric acid, containing 20 per cent. of anhydride, while the temperature is kept below 40‹ C. After standing at the ordinary temperature for 24 hours, the mixture is poured upon a mixture of ice and water, and the saccharin precipitated thereby is washed with cold water and dried. The yield is 95 per cent. of the theoretical one. The Provisional Specification mentions also the use of phosphorus oxychloride as a dehydrating- agent. The o-salphamidobenzoic acid employed may be obtained by oxidizing crude toluolsulphamide containing 75 per cent. of the ortho compound with permanganate in dilute soda lye, boiling the concentrated solution of saccharin and o- and p-sulphamidobenzoic acids thus obtained until the saccharin is saponified, precipitating the p-sulphamidobenzoic acid by stirring in dilute mineral acid until a weak acid reaction on congo paper takes place, and finally precipitating the o-sulphamidobenzoic acid, which is quite free from the p-acid, by further addition of mineral acid.

Title: Improvements in Electricity Meters.
Filed: 1900-02-19
Granted: 1901-01-19
Abstract: 3237. Chamberlain & Hookham and Holden, S. H. Feb. 19. Quantity meters.-A motor meter has a conical or cup-shaped copper armature e immersed in mercury, with its point or convex surface downwards, to throw off air bubbles. The armature revolves in two magnetic fields between an iron block d and pole-pieces b on a long magnet a ; the mercury space is enclosed by a non-conducting ring h, two pieces of non-magnetic material between the pole-pieces, and a central plug i. Current is conveyed to the armature by conductors k, l passed through the ring h, and the armature is retarded by eddy currents induced in it. In order to compensate for the diminution in these eddy currents when the resistance of the armature is increased by rise of temperature, a comparatively large resistance o, made of material such as iron having a higher temperature-resistance coefficient, is connected in series with the armature, and the whole is shunted by another resistance r, made of material having a lower coefficient, such as manganin or platinoid ; thus, when the temperature rises, a smaller proportion of the main current passes through the armature, to drive it. The meter is a modification of those described in Specifications No. 14,239, A.D. 1892, and No. 2683, A.D. 1896. Resistances. - The Provisional Specification mentions the use of amalgams for the shunt resistance. Motor meters of any kind having eddy current brakes may have the temperature errors of these compensated by the means above-described. In some cases, the series resistance must have a low temperature-resistance coefficient, and the shunt a high one.
