Granted: 1900-12-15
Abstract: 25,734. Timofeeff, P. Dec. 30. Building and paving blocks; slabs.-Relates to the manufacture of artificial stone for building and paving blocks and slabs &c., and to the manufacture of cements for uniting the blocks. Materials, such as clay, limestone, brick, stone, and rubbish, together with fluxes, alkalies or alkaline earths, lime, oxides, mineral colouring- matters, &c., are ground to a fine powder and melted at a high temperature in furnaces such as those employed in melting steel or glass. The fused material is cast or pressed in moulds, to form blocks, which are afterwards annealed in the same manner as glass. The cement employed for uniting the blocks consists of lime together with calcium silicate, or of ordinary cement together with the pulverized artificial stone. Ordinary cemeut may, however, be employed, without modification. When great hardness is required, quartz sand is mixed with the molten materials just before casting. The blocks may consist of a core of one kind of the fused material covered by fusion with a layer of a different composition. The outer layer may, however, consist of a mortar composed of soluble glass and quicklime, applied like a paint. Proportions are given for a composition consisting of quartz sand, red clay, lime, river silt or mud, and brown iron ore.

Title: Improved Means of Preventing the Refilling of Bottles and Receptacles.
Inventor: BIZOUARNE LEON FERDINAND
Filed: 1900-06-19
Granted: 1901-04-27
Abstract: 11,121. Bizouarne, L. F., and Kugler, E. June 19. Stoppers; refilling, preventing.-The neck of the bottle &c. is fitted with a lining a, Fig. 1, closed at its upper end by a diaphragm d, and contracted at its lower end h to form a seat for the cork plug or valve i, which is attached toa a bent tube k. Within the lining are arranged two siphon tubes c, b for the outlet of the liquid, and two siphon tubes l, m for the admission of air. The siphon b is inverted, its longer arm opening through the diaphragm d, while the longer arm e of the siphon c is spirally twisted and forms a second diaphragm for the lining. When the bottle &c. is inverted, the liquid flows out through the chambers and siphons g, c, n, b. If it is attempted to refill the vessel while it is in an upright, inclined, or horizontal position, the liquid enters the chamber n, and by closing the tube m compresses the air within the vessel, so that the liquid cannot enter the latter. If it is attempted to force in liquid, the pressure will tend to straighten the tube k, which will break and allow the valve i to be forced on to its seat. In the modification shown in Fig. 6, the liquid-outlet siphon c and air-inlet siphon l are arranged between two diaphragms p, d in the lining a, the passage h being normally closed by the valve i. The diaphragm d is preferably made convex on the top, to prevent it from being perforated, and is formed with inclined holes d<1>, or with radial inclined grooves, to serve as ports for the liquid &c.

Abstract: 18,667. Brown, A. B. Oct. 19. Starting-engines.-The engine is so arranged as to enable the valve gear of a large engine to be adjusted by steam power or by hand as desired, and so that, when steam power is to be used, the usual automatic stoppage after a predetermined movement has been effected can be avoided, and the engine be converted into an " all-round gear." The weigh shaft of the main engine is operated by a suitable connection with the crank-pin A on the worm-wheel B. The worm-wheel B gears with the worm C, which can be rotated by the fastrunning engine shown through bevel gear G, F, but also, when the wheel G is disengaged from the wheel E, by the handing-wheel E. The fast-running engine is controlled by a valve operated by the lever N fulcrumed at P, and it is started by an adjustment of the lever N by means of the handlever X, and is stopped again by the resulting movement causing one or other of the pins 8, T acting on the pin Q to restore the lever N to its primary or neutral position. The "all-round" action is introduced by shifting the pin Q in the slot R so as to be out of the path of the pins S and T.

Title: Improvements in the Manufacture, or Preparation, of Cyanamide, and its Compounds
Inventor: JOHNSON GEORGE WILLIAM
Filed: 1901-02-15
Granted: 1902-01-16
Abstract: 3328. Johnson, G. W., [Deutsche Gold & Silber Schelde Anstalt vorm. R÷ssler]. Feb. 15. Cyanamides.-Disodium cyanamide, Na2N2C, is produced by heating sodium amide with carbon or a carbonaceous substance at about 380‹ C., and then further raising the temperature to about 550‹ or 600‹ C., i.e. above the melting point of disodium cyanamide. The process may also be carried out by melting sodium in a crucible, adding carbon, and then passing in ammonia through the mass. When other alkali metals are used, the temperatures are varied, and the corresponding alkalimetal cyanamides are produced. Other salts of cyanamide are precipitated upon adding concentrated solutions of salts, such as calcium or lead salts, to a concentrated solution of a dialkalicyanamide. Cyanamide itself is obtained by adding sufficient oxalic acid to a concentrated solution of disodium cyanamide and separating the sodium oxalate thus formed.
