Discharging.-Relates to a ladling machine for taking up material from a container, such as a furnace or melting-pot, carrying it to the working point, and then pouring it, the ladle being so mounted that it can be rotated about three different axes when gathering or pouring. The machine is described as adapted for ladling glass from a furnace and for pouring it on to the table of a rolling - machine. The machine comprises a frame 1, Fig. 1, which runs on rails 2, a carriage 4 which runs on rails on the frame 1, its track being transverse to the rails 2, and circular platform 5 pivoted on the carriage 4. The platform 5 carries a supporting-bracket 7 on which bearings 9 are mounted, and the front end of a cradle 10, Figs. 1 and 5, is journaled in these bearings. The ladle 14 is carried by a shaft 12 which is journaled in a cylindrical member or " cannon " 11. This " cannon " has two cheeks 17 which are secured to a shaft 18, parallel with the shaft 12 and journaled in bearings on the upper part of the cradle 10, and the axis of the shaft 18, if extended, would pass near the pouring lip of the ladle. A counterweight 19 balances the weight of the "cannon" and the ladle. The cradle is tilted about the bearings 9 by a compressedair cylinder 38, and another cylinder, operating a rack 21, swings the " cannon " about the shaft 18. The ladle can be turned by these cylinders about the axes of the shaft 12 or 18, and also about the axis of the bearings 9. These movements enable the ladle to be inserted in the furnace 3 and dipped to gather metal, and then withdrawn and moved to deposit the charge on the table of a rolling machine. Movement of the " cannon " about the shaft 18 is obtained by means of a strap 26, Figs. 1 and 6, loosely mounted on the shaft, which is connected by a rigid rod 30 with the frame of the machine. A pawl 28 on the strap engages teeth on a wheel 25 which gears with another wheel on the shaft 12, and movement of the cradle about the bearings 9 turns the " cannon " about the shaft 18 and also rotates the ladle about its axis in either of these movements. Means are provided for locking the " cannon " to the cradle when desired, and a handwheel 29 is provided to enable the ladle to be turned or to be moved from the furnace in case the air supply should fail.

Title: Improvements in or relating to the fuse-setting mechanism of anti-aircraft guns
IPC: F42C17/00
Filed: 1919-06-25
Abstract: 140,044. France, State of. March 13, 1919, [Convention date]. Sights.-Relates to fuse-setting devices for use with anti-aircraft guns, of the kind in which the device is automatically rotated into the setting position, by the operation of maintaining a pointer opposite a curve representing the given altitude of the target, this curve being one of a set which indicate the variation of fuse-setting with angle of sight. The invention consists in mounting the graphs on a drum rotatable automatically in accordance with the angle of sight, and in adapting a hand-wheel simultaneously to displace the pointer in a direction parallel to the axis of the drum and to operate the fuse-setting device. In the form shown, a drum G carries graphs, each plotted for a given altitude by taking angles of sight as ordinates and the corresponding fuse settings as abscissµ. The drum is rotatable in accordance with the angle of sight, and a pointer on u member E carried un a screw V is manually displaced, by rotating a hand-wheel R, to maintain it on the curve corresponding to the given altitude. This operation simultaneously rotates the fuse-setting device D through the gearing S, T, M. Fuse-setting corrections may be applied to a corrector mounted on the pointer, as, for example, in the manner described in Specification 127,568.

Abstract: 1,102,164. Semi-conductor devices. TEXAS INSTRUMENTS Inc. 14 April, 1965 [15 April, 1964], No. 16021/65. Heading HlK. In making a semi-conductor device impurities are simultaneously diffused into a semi-conductor wafer from overlapping layers respectively containing impurities of opposite conductivity types and different diffusion characteristics to form side-by-side layers of opposite conductivity types extending to different depths. In a typical embodiment a planar NPN transistor is made in multiple by first depositing phosphorus doped oxide on an N-type silicon wafer from a gaseous mixture of tetraethylorthosilicate and phosphorus oxychloride or tribromide and reducing it to isolated areas (2 in Fig. 1) by photoresist and etching steps. Then a layer of gallium doped silicon oxide is deposited from a mixture of the orthosilicate with triethyl gallium and etched back to form areas 3 covering and extending around areas 2. Next undoped silicon oxide 4 is deposited by pyrolytic decomposition of silanes over the doped layers and the assembly heated to 1200 C. to diffuse in the gallium and phosphorus to form base region 6 and emitter 5. Apertures are then provided in the layers to accommodate electrodes 7, 8 formed by deposition and photo-resist and etching steps, and the wafer divided into single elements for attachment to headers 9. Formation of PNP structures using oxide layers containing phosphorus and boron as dopants is also suggested, the boron doping being achieved by incorporating tripropyl borate or boron tribromide in the tetraethylorthosilicate. The method is also said to be applicable to germanium and gallium arsenide wafers.
