Granted: 1901-09-28
Abstract: 14,463. O'Rourke, J. F. July 16. Foundations; bridges; walls.-Relates to the construction of great lengths of the waterresisting walls employed for subaqueous or subterranean foundations, and consists mainly in the arrangement of caissons shown in horizontal and transverse vertical sections in Figs. 2 and 3, respectively. Each separate caisson is built up of vertical timbers A bound together by horizontal angle-irons B, and a roof E is provided. The hole F in the roof opens into the air shaft and a second hole F<1> near one end of the caisson is normally closed by a cover G. One separate caisson is first sunk to the desired depth, and within it is built as much as is possible of the water-resisting wall, with the exception of a semicylindrical part H at the end under the hole F<1>. A second caisson is then sunk into position in line with the first and the abutting-ends are secured together so as to give a water-tight joint about the middle timbers. The lower angle-irons band the middle timbers a of the abutting-ends are then removed, and the wall M, Fig. 5, constructed in the first sunk caisson, is continued through the opening into the second-sunk caisson, in which is then built the next length N of the wall. The covers G are taken off to allow the upper angleirons b and middle timbers a<1> to be removed, whereby the two parts M, N of the wall can be more securely connected. The next length is connected in the same way, and so on until the whole wall is completed. The two vertical ends of each separate caisson may be slightly inclined to each other, so that the fully-constructed wall may enclose a circular or polygonal space, which may afterwards be filled with concrete or the like, to form a foundation for a building or pier. In a modified form, the roof E may be dispensed with, and the uppermost angle-iron B' is in that case fixed below the upper ends of the timbers A, which engage with the lowermost projecting angle-iron B' of a coffer-dam extension A'.

Title: Improvements in Obtaining Hydrocyanic Acid from Ferrocyanides and in Apparatus therefor
Inventor: CRAIG GEORGE
Filed: 1901-12-02
Granted: 1902-12-02
Abstract: 24,456. Craig, G. Dec. 2. Hydrocyanic acid and its salts.-Relates to the production of hydrocyanic acid from ferrocyanides, more particularly those obtained in the recovery of cyanogen from coal gas, such as alkaline, alkalineearth, or metallic ferrocyanides, or mixtures thereof which may contain also chlorides, sulphates, sulphides, or other substances. The metallic ferrocyanides, unless they are present only in small quantity, are first converted into alkaline or alkaline-earth ferrocyanides by treatment with caustic alkali or alkaline-earth. The process then consists in distilling the mixture with an excess of dilute sulphuric or hydrochloric acid, with or without the addition of magnesium sulphate, or other salt, which facilitates the expulsion of the hydrocyanic acid, in a still fitted with a reflux condenser. The gases produced are passed through a purifier containing white lead in suspension and then through a condensing-worm to an absorber containing caustic alkali. An ejector is fitted to the absorber for drawing a current of air or gas through the apparatus. The residual solution is run off, and any metallic ferrocyanide originally present, or produced in the process, is allowed to settle. This may, if sufficiently pure, be dried, or if not, when a sufficient quantity has accumulated, it may be converted into alkaline ferrocyanide and be subjected to the original process. Other salts present in the residual lye are crystallized out, and the acid is used again in the process. When hydrochloric acid is used, the reflux condenser employed is made of earthenware, glass, porcelain, or the like, and is kept at 40‹ C. The acid is recovered from the residual lye by distillation.

Abstract: 14,040. Preston, E. J., and Ralston, G. C. June 20. Windows, sliding. The sliding windows operated by toothed and worm gearing described in Specification No. 8551, A.D. 1901, for ships' sidelights are now modified to adapt them for railway-carriage windows of light weight. In the form shown in Fig. 1, the sash is supported on a spring f carried at its ends by vertical racks c which can slide in grooves in the framing. The sash is raised or lowered by the rotation of a quick-threaded screw h by means of a sliding nut with a handle K, the screw having at each end a pinion engaging the rack. When the sash is fully raised, further rotation of the screw raises the racks slightly higher, flexing the spring f, and bringing into action wedges on the racks, which force the sash outwards against its seat. The racks may be formed on the sash, and, instead of wedges, the sash may be forced on to its seat by eccentrics turned by handles. The seat may be faced with rubber. In the form shown in Fig. 3, vertical screws are substituted for the racks, each screw engaging a nut or nuts on the sash; or nuts on the screws may each engage a tooth on the sash. The screws are adapted to move slightly in a transverse direction with the sash by the action of the wedges. In the form shown in Fig. 6, the sash is raised and lowered by lazy-tongs operated by a bell-crank lever 2, or by a vertical screw and nut. In an arrangement applicable to double sliding windows, horizontal or vertical right and left handed screws are employed to separate the sashes or bring them together. The screws are rotated by bevel gearing.
