Title: Improved Method of Tunnelling Under Streets, Roads, Squares, Tracks and the like Surfaces of the Ground.
Inventor: KNUDSEN JENS
IPC: E02D29/055
Filed: 1908-06-20
Granted: 1909-02-11
Abstract: 13,189. Knudsen, J. June 20. Excavating, methods of.-In a method of tunnelling under roads &c., a trench is first made in the ground to the depth of the under surface of the roof of the tunnel, the roof is made on the bottom of the trench, the surface of the road is re-made on the roof, and the tunnel is excavated under the roof. Before or after the trench is made, two rows of girders e are driven into the ground, the tops projecting slightly into the space to be occupied by the roof. Between the girders e two or more rows of piles x are driven with their heads a little below the levelled earth, to accommodate beams z which are placed longitudinally on them. Concrete a for the roof is then placed on the levelled earth and is covered with a layer of tarred felt or the like c and finally by a thin layer of cement-concrete d. The road surface is then re-made. After the concrete has set, a drift with sloping sides is made to about half the depth of the tunnel so that the piles x and beams z become exposed. The upper ends of each transverse pair of piles x are then connected by cross-beams y, and the entire cross-section of the tunnel is gradually removed. When the girders e are exposed, planks m are inserted longitudinally between them, forming walls. The walls and bottom of the tunnel are covered with a thin layer of concrete n on which tarred felt is placed, and the side walls o are then made. When these have set, the piles x and beams y, z are removed and the floor is made. In a modified method, after the roof has been made, preferablv on a layer of planks, a drift is excavated to the bottom of the tunnel and planks f and struts g are put in place. Scaffolds p, which may be provided with screw spindles k, are next inserted on sleepers h and support girders i and beams j. The props g and planks f are then removed and the excavation proceeded with, planks m being placed between the girders e. The scaffolds p are finally removed, and the tunnel is completed.

Title: Improvements in Melting and Casting Magnesium and Alloys thereof.
Inventor: JOHNSON GEORGE WILLIAM
Filed: 1908-07-15
Granted: 1909-07-15
Abstract: 15,038. Johnson, G. W., [Chemische Fabrik Griesheim Elektron]. July 15. Casting.-To prevent oxidation during the melting and casting of magnesium and alloys thereof, pieces of the solid metal are added at intervals to the metal in the melting crucible or vessel, so that the melt always contains solid metal and is kept in a pasty condition. When the addition of solid metal is finished, the crucible is immediately removed from the fire, and the metal is stirred energetically ; it thereby receives sufficient heat from the walls of the crucible to give it the fluidity necessary for casting without reaching the oxidizing temperature of magnesium. In making magnesium alloys, the magnesium may be first melted as described above, pieces of the metal to be alloyed therewith being previously heated to a temperature not above that of the magnesium bath and then introduced therein; or a small quantity of magnesium may be melted, and heated pieces of alloying-metal introduced alternately with pieces of magnesium. The melt is finally removed from the fire and stirred energetically before casting, as described above. The process is only applicable to alloys having a melting point below or near to that of magnesium, for instance, alloys of copper and magnesium containing not less than 25 per cent of the latter metal.

Title: Improvements in Liquid Supply Regulators.
Inventor: HAMILL WILLIAM WILSON
IPC: G05D16/06
Filed: 1909-11-19
Granted: 1910-06-30
Abstract: 11,774. Hamill, W. W. Nov. 19. Oil supply.-In apparatus in which a supply of liquid requires to be regulated so as to preserve a constant level, such as internal-combustion engines, lubricators, lamps, &c., the supply is regulated by means of the pressure of a column of liquid, connected to the receiver, acting either directly or through the medium of compressed air in a piston valve. The column of liquid is contained in a vessel a formed as a gauge-glass and communicating with the receiver through the strainer m<4> and fitting m<5>. The lower end of the chamber a communicates with a chamber b, from which a passage e leads by a circumferential groove in the piston-valve f to the supply fitting h. When the liquid rises in the chamber a, the air compressed in the upper part of the chamber b acts on the diaphragm i to move the valve f against the spring k and cut off the supply. The apparatus may be mounted so that its height, and consequently the liquid level maintained, can be adjusted. Modifications are described in the arrangement of the valve f and chamber b, others in which the valve is controlled by gravity or liquid pressure instead of the spring k, and others in which the chamber b is dispensed with, and the liquid acts directly in the diaphragm i.
