Patent GB-189907868-A (GB)
Title: Improved Process for the Purification of Anthracene.
Filed: 1899-04-14
Granted: 1899-07-08
Abstract: 7868. Aktiengesellschaft f³r Theerund Erd÷l-Industrie and Kraemer, G. April 14. Anthracene.-Consists in purifying crude anthracene by the following processes :-The crude material is fused, and then allowed to cool in a well-insulated metal kettle until about 50 per cent. of the mass has crystallized. The liquid portion is thereupon run off and allowed to cool, and the crystals obtained may be subjected to the same operations for recovery of a further quantity of anthracene. The crystals are re-melted in a vessel fitted with a stirrer, and caustic-potash solution of 50 per cent. strength is stirred in, while the temperature is raised to not more than 260‹ C. After stopping the stirrer, the lower layer, which consists of potassium carbazole. is run off. The upper layer, consisting of anthracene and phenanthrene, is run into commercial benzole of 90 per cent. or into solvent naphtha, whereby the phenanthrene is dissolved. The mixture is then pressed or centrifuged, and washed with more benzole, whereby a fine brown powder containing upwards of 90 per cent. of anthracene is obtained.

Title: Improvements in or relating to Bilge Blocks for Dry Docks, Floating Docks, or Slipway.
Inventor: LEWIS RICHARD
Filed: 1900-01-15
Granted: 1900-06-16
Abstract: 885. Lewis, R. Jan. 15. Docks; slips and grids, building, launching, and repairing.-Relates to an adjustable bilge-block for use in dry docks and the like, and is shown in side elevation in the Figure. The bilge-block W, pivoted at Z to the framing C, rests upon the vertically-movable part of a screw-jack J. This part is raised or lowered when the screw is rotated by means of the hand-wheel V, rod T, wheels R. adjustable rods L, and wheels 5, I, of which the latter rests in a bearing on the platform H. This platform rests on a lower platform B, which turns about an axle F so that pressure on the bilgeblock has a slight tendency to rotate the platform B about the axle F in a direction opposite to the hands of a clock. To the end of the platform, one end of a wire Q is fixed, the other end being fastened to a spring balance U, whereby the pressure on the bilge-block is indicated to the person operating the hand-wheel V. An indicator S is arranged to show the position of the screw J, and, in a modification, two bilge-blocks are operated from one hand-wheel.
Patent GB-190002665-A (GB)
Inventor: DELATURE JULES
Filed: 1900-02-10
Granted: 1900-05-12
Abstract: 2665. Delattre, J. Feb. 10. Sewage and foul waters, treating; agitating; precipitants etc.; settling; filtering.-Relates to the treatment of waste and impure waters, particularly such waters as contain greasy matters, by apparatus such as is described in Specification No. 555, A.D. 1899. The waters are pumped into a channel, where they are thoroughly mixed with sulphuric acid or an equivalent reagent, such as any mineral acid, ferric sulphate, sulphate of aluminium, perchloride of iron, acetates, acid superphosphates, alum, dolomite, etc.; the mixed liquid then passes into settling-tanks, and is decanted and filtered, and, after the filtrate has been neutralized by milk of lime, grease is extracted from the neutral liquid by means of a solvent. The apparatus employed in the process of extracting the grease comprises cylindrical sections a, i, b, connected by pipes c and provided with spoon-shaped agitators d mounted on rotary shafts. The liquid is admitted into the upper section a by means of a pipe f, and the solvent is supplied through a pipe g, and a heating-coil l, fitted in the discharge pipe k, serves to vaporize any solvent carried into the pipe k by the descending liquid ; baffles n prevent the escape of the vapours without mixing with the liquid. The solvent, charged with the greasy matters, is withdrawn through an outlet pipe j. When sulphuric acid is not used, a simple filtering process is employed instead of the neutralization by means of lime.
Patent GB-190002855-A (GB)
Title: Improvements in Acetylene Gas Generators.
Inventor: FORBES CHARLES STEWART
Filed: 1900-02-13
Granted: 1901-01-12
Abstract: 2855. Forbes, Sir C. S. Feb. 13. Acetylene.-Relates to apparatus suitable for use with magic or projection lanterns or as a portable generator. Within the gas-holder bell 3, which is fitted with a handle 2<a> for removing it from the tank 1, is fixed a cylinder 6 cut away so as to leave side pieces 6<a> and a collar 6<b> provided with bayonet slots 7. The carbide holder 8 is provided with pins 7<a> by which it is supported in the cylinder 6. It is open at the top and closed at the bottom, and has a small hole 9 near the top opening into a tube 10 which extends to near the bottom of the holder. In operation, water enters the carbide holder by the hole 9 whenever the bell 3 sinks sufficiently low, and, when the gas is produced more rapidly than it is used, the bell 3 is lifted so as to raise the hole 9 above the water level and thereby out off the supply of water. The gas passes by a pipe 11 to a water trap 12 fitted with a drain cock 13, and thence it passes through a purifier 16 to the distribution pipe 18. Several carbide holders may be mounted in one generator. In a modification, a supplementary gas holder is interposed between the gas holder 3 and the purifier, and the gas delivery pipe of such supplementary holder is also provided with a water trap and drain cock. The gas holder 3 in this form is fitted with a central guiding-tube which carries a flange for supporting several carbide holders. In some forms, the gas bell is fixed, and the water is forced down by the gas. Excessive variations of pressure are in these cases avoided by fitting the carbide holders with caps provided with a small hole for equalizing the rate at which the gas escapes therefrom into the gas holder.

Abstract: 12,760. Sauerbrey, R. June 22. Evaporating brine; residues, removing; vacuum apparatus.-Relates to that kind of vacuum apparatus for evaporating brine in which each evaporator v, Fig. 4, is provided with two separators a, a', with each of which the evaporator is alternately connected, so that the separated salt can be removed from one without impairing the vacuum while the other is being filled. The connection and disconnection of the separators is effected by opening and closing the valves b<1>, b<2>, and the object of this invention is to replace these valves by elbow pipes k, k<1>, Fig. 1, which can be turned through an angle of 90‹, so that, in the positions shown in Fig. 1, the separator a is connected with the evaporator and the separator a' is disconnected from it. The outflow from the separators is led back to the same evaporator or to another evaporator through pipes c similarly arranged. Each set of pipes is connected by rods p, p<1>, g, g<1> to blocks h, h<1>, mounted on a screw spindle i, so that, by turning the spindle, the pipes may be simultaneously moved to the operative and non- operative positions respectively. The rods for the two sets of pipes are driven from a single shaft d. The engagement of the belting for communicating motion to the shaft d is effected by hand, but the disengagement is effected automatically by the rod m, which is actuated by the action of the rods g, p' on the pins s, t.

Abstract: 15,601. Silberstein, A. L. Aug. 1. Sharpening.-In a razor-stropping device, the razor blade x is held firmly in the trough-shaped holder a by a spring h, Fig. 5, and the razor handle y is held by a clip i on a piece b capable of sliding on the holder a against a stop k. The holder is pivoted to the cross-piece c, and has a spur-wheel o for engaging with a tooth sector p fixed to the handle e. The piece c carries bars d for contact with the strop, and is pivoted at f to the handle so that it can rock as shown by the dotted lines. Stops g limit this motion. A spring or springs q tend to turn the holder a until it lies in a line with the handle. In use, the bars d are reciprocated on the strop, and at each fresh stroke the bars rock on the pivot f, and thus reverse the position of the razor blade.
