(2.) The device of claim 1 having the connections between the motor and signal or other object characterized by an operating-belt driven by the motor and a magnetically controlled clutch, connected with the signal, and adapted to connect or disconnect the signal with the belt. (3.) The device of claim 1 characterized by a clutch connected with the signal or other object adapted to engage or not with the detachable portion, and a catch for engaging with the clutch when the connection between the clutch and detachable portion is broken, to hold the signal in set position, and means for causing the clutch to engage with or be freed from the detachable portion of the catch. (4.) The device of claim 1 having the connections between the motor and the signal characterized by a rotary power-wheel. (5.) The device of claim 4 characterized by an arm, connected with and adapted to move the signal and mounted concentrically with the power-wheel and provided with a magnetically controlled clutch adapted when energized to engage with the power-wheel to move the signal to set position. (6.) The device of claim 5 characterized by a magnet controlling the clutch and mounted upon and movable with the arm. (7.) The device of claim 1 having the connections between the motor and the signal or other object characterized by a clutch, and a locking-device therefor, electrically controlled, the clutch and lock being flexibly connected together and so arranged that when the locking-device is held in its locking position the clutch will operatively connect the motor with the devices for operating the signal or other object to move the signal or other object into set position without moving the magnet, and when the locking-device is in its inoperative condition the clutch will be inoperative and the signal or other object will be disconnected from the motor. (8.) The device of claim 5 characterized by a locking-device flexibly connected with the clutch and a stationary magnet controlling the locking-device, substantially as described.

No. 13787.—5th July, 1901.—GUSTAVE LOUIS MOUCHEL, of 38, Victoria Street, London, England, Engineer, and CONSTANT ELIET, of 24, Rue Bellefontaine, Lorient, France, Civil Engineer. Improvements in concrete and metal partitions.

Extract from Specification.—This invention has for its chief object to provide an improved construction of concrete and metal partitions capable, when arranged vertically, of withstanding lateral or horizontal pressures, such, for example, as in the case of the outer and inner walls of silos, bins, granaries, warehouses, and other structures and receptacles, and also, when arranged horizontally, of withstanding vertical pressures, as in the case of floors and the like. According to this invention, such partitions are constructed of concrete, having imbedded in it a strengthening skeleton or framework of metal composed of practically rigid longitudinal members—that is to say, members extending between the main or end supports of the partition—in a suitable combination with practically rigid transverse members—that is to say, members arranged substantially at right angles to the said vertical members. The longitudinal members are made of metal bars, curved or arched in such a manner as to effectually take up the strains. The transverse members are made of preferably straight metal bars of any suitable form in cross-section, arranged preferably parallel to one another at suitable intervals apart. In the case of vertical partitions the longitudinal members are horizontal, and are curved or arched in a horizontal plane, with the convex side of the arch or curve directed in the opposite direction to that of the pressure the partition is designed to withstand. In vertical partitions which are liable to horizontal pressure on both sides the longitudinal members are arranged in two series—that is to say, one series of longitudinal bars are arranged with their convex curvature or arch towards one side of the partition, and another series of longitudinal bars are arranged with their convex curvature or arch towards the opposite side of the partition. In general, it is preferred to arrange the ends of the one series of longitudinal bars so as to overlap the ends of the other series of longitudinal bars, so that the overlapping ends of the two oppositely curved or arched series of longitudinal bars when seen in plan have the appearance of a swallow’s tail. In the case of vertical partitions which are required to withstand horizontal pressure from one side only, only one series of longitudinal bars presenting their convex curvature or arch towards that side of the partition may be employed. In constructing vertical partitions according to this invention, it is preferred to arrange the metal framework of the same in such a manner that the ends of the longitudinal metal members or bars of each partition will overlap in plan the ends of the longitudinal members or bars of the adjacent and intersecting partition or partitions, with the object of obtaining a better bond between the several partitions at their junctions and intersections. Instead of making each vertical or horizontal partition in one solid piece at the time of erection, such partition may be constructed of self-contained partition bodies or slabs or blocks of concrete, moulded separately beforehand according to this invention. Such slabs for vertical partitions may be made at their ends with tongues, grooves, or other suitable devices to facilitate making the joints on erection. The slabs may be made with the ends of their longitudinal metal members either projecting from the concrete or embedded in the same. To form the angle or connection between four intersecting or adjacent partitions, the slabs may be arranged in the form of a cross in such a manner as to enclose between them a rectangular cavity in plan, and with the projecting ends of their longitudinal metal members overlapping one another in plan, in said cavity, which is then filled with concrete or cement to form the joint.

[NOTE.—The number and length of the claims in this case preclude them from being printed, and the foregoing extract from the descriptive part of the specification is inserted instead.]

No. 13788.—5th July, 1901.—JOHN BREEDON, of John Street, Granville, near Sydney, New South Wales, Brickmaker. An improved method, with apparatus therefor, for treating kaolin, slimes, saponaceous earthy matter, and the like, preparatory to the extraction, by either amalgamation, chlorination, leaching, or suchlike processes, of the precious metals contained therein.

Extract from Specification.—By means of this invention kaolin, slimes, saponaceous earthy matter, and the like are treated with the object of converting the pulpy, slimy, or tenacious material into coagulated pieces preferably of tubular or channel formation, and of dimensions suitable for immediate furnacing, by which they are adapted for subsequent treatment by means of extraction processes, such as amalgamation, chlorination, leaching, or the like. The initial operation, when treating pulpy or slimy matter, comprises the use of an evaporating-table suitably heated, combined with an endless conveyer fitted with cutting-appliances for separating the layer of material during its passage over the evaporating-table so as to facilitate the escape of the moisture, thus hastening the drying operation. The material passes from thence into an expressing appliance suitably constructed to create tubular, channelled, or suchlike elongated formations, the said appliance being further provided with means for filling, wholly or partially, the tubes or channels (during the period of the expressing operation) with an inflammable material, which will be of service during the subsequent calcining operation. Combined with the said expressing appliance is a multitubular heating-chamber, through which the expressed material passes in its elongated form, and is partially dried. In its outward movement it is caused to pass between suitable cutting-appliances, and is divided into pieces of any desired length. The said material passes thence to the heated surfaces of a series of shaking-tables, set at a desired angle, and having an impulsive action imparted to them by which the pieces are moved (and hardened during the movement) onward towards an exit, where a conveyer is located to receive and discharge them on to a trough having a distributing conveyer, by means of which they are passed into a kiln of special construction, adapted for the immediate furnacing and perfect calcination of the coagulated tubular pieces which require no special method of setting, but may occupy a jumbled state within the chambers. The tubular and channelled formation of the pieces provide the necessary interstices and spaces for the passage of the heat, which is generated in adjacent chambers, from whence it is conveyed to the inflammable material within the coagulated pieces. The furnaces adjacent to the calcining-chambers are placed one above the other, and are fed from upper openings. Fire-ducts and heating-flues are also provided so as to permit of
