Title: Improvements in or relating to an apparatus for fastening together the ends of a binding member or strap
IPC: B65B13/34
Filed: 1937-09-21
Abstract: 490,800. Feeding - devices for flat articles. STEVENS, A. H. (Leechgrip Co.) Sept. 21, 1937, No. 25607. [Class 117] [Also in Groups XV and I] A device for fastening together the ends of a binding strap comprises a magazine for holding a number of separate flat clip blanks and mechanism for individually feeding a blank from the magazine over the strap ends. During the preliminary movement of a shear lever 34 a pin fixed to a collar on the shaft of the lever, and which engages a cam slot in a shuttle lever, reciprocates the latter. On the end of the shuttle lever is pivoted an extension 74, and a spring is mounted on the pivot so that the extension will remain in any raised or lowered position to which it may be moved. The extension engages a face 85 on a shuttle 79, mounted to slide in a guide 80. Flat clip blanks 61 are stacked in a magazine 62, provided with a sliding door 64 and a spring pressed follower 65. At every forward movement of the shuttle lever a spring pressed pawl 87 mounted on the shuttle feeds forward the lowest blank 61. If the movement is completed a spring 93 engages and raises the extension 74, so that, on the return movement of the lever, the extension can engage a shoulder 86 on the shuttle and return it. During this movement the extension is returned to its lower position by an edge 94a on the shuttle guide. If the forward movement is not completed the extension 74 will miss the shoulder 86 on the return movement, and therefore fail to return the shuttle, so that a second blank cannot be fed unless the previous one has been fully fed into position.

Abstract: 186,910. Martini & H³neke Maschinenbau-Akt.-Ges., (Assignees of Hurlbrink, E.). Oct. 5, 1921, [Convention date]. Fluid-actuated valves.-A safety cut-off device for use in connection with plant for storing imflammable liquids under protective gas and having the external conduits surrounded by gas jackets comprises a cut-off valve in the feed pipe connected to an actuating member subject on one face to an actuating member and on the other to the pressure in the storage chamber. In the form shown, the valve 5 controls the flow through a pipe 2 protected by a gas jacket 4 which jacket is isolated from the storage chamber 1 but is connected by a pipe 11 to a diaphragm chamber 20. The valve 5 is mounted on a hollow spindle 6 which passes through a stuffing-box 8 into the diaphragm chamber and is coupled to a diaphragm 7. The outer face of the diaphragm is open to the pressure in the container while, jacket pressure admitted through the conduit 11 acts on the inner face. As the valve 5 closes the end of the hollow spindle is adapted to draw away from a plate 19 carried by a bridge 12 and so directly connects the gas space in the reservoir with the pipe 2 to stop the flow of liquid. In a modification, a diaphragm replaces the stuffing- box and the jacket pressure is transmitted to the actuating diaphragm through a volume of liquid adapted to pass through a restricted orifice to damp the movement of the valve. In another modification, a shuttle type valve is connected by a lever to a diaphragm immersed in a liquid, the whole device being arranged outside the storage vessel. In a further modification, a double seated lift valve is actuated by an annular diaphragm surrounding the outlet pipe.

Title: Process of treating tin sulphide concentrates
IPC: C22B5/02
Filed: 1944-12-28
Abstract: A pyrometallurgical process for treating tin bearing materials, containing sulphur and iron as impurities, to recover tin metal, which comprises forming a charge by intermixing up to 30 per cent. of sodium carbonate and optionally up to 2.5 per cent. of coke with the tin bearing material, smelting the charge to form a tin sulphide-soda-iron matte, introducing metallic iron into the molten mass in sufficient amount to react with the matte and produce a soda-iron-sulphide matte phase containing not more than 1 per cent. of tin and a tin metal phase containing less than 1 per cent. of each of sulphur and iron.  Where necessary sulphur is added to the charge to assist in the formation of the tin sulphide-soda-iron matte.  The addition of metallic iron may be performed in more than one stage, the last addition being in excess of the quantity required to replace the tin in the matte, thereby producing a matte containing less than 1 per cent. of tin which may be discarded, a tin metal phase low in iron and sulphur, and a final tin metal product high in iron content which provides part of the metallic iron added to a succeeding charge.  The operations may be carried out in a reverberatory furnace at a temperature within the range 1800 DEG F. to 2000 DEG F.
