Title: A method of and a device for extruding metals, particularly easily oxidising metals
IPC: B21C29/00
Filed: 1950-12-22
Abstract: 691,875. Extruding. HIRSCH KUPFERUND MESSINGWERK GES. Dec. 22, 1950 [Oct. 1, 1948; Oct. 1, 1948], No. 31221/50. Class 83 (iv). In a method of extruding metals, scale forma. tion is avoided by preventing the access of air to the extruded metal until it has cooled down to a temperature at which oxidation cannot take place. In one example, short extruded lengths are discharged from a die 2, Fig. 1, into a tube 5 containing a protective gas supplied through inlet and outlet pipes 6, 7 and which may be below atmospheric pressure. After cooling, the lengths are removed through a sealing door 8. In another example the work is discharged through a pipe 5, Fig. 2, containing steam, and then passes through a tube 16 containing cooling water moving in the same direction as the work. The tube 5 is enclosed at one end by a chamber 11 containing steam and which acts as a sump for preventing water from reaching the die as a result of condensation of steam or backward flow from the pipe 16, a gap 18 and holes 19 being provided for draining purposes. Inert gas or steam may be passed into the pipe 5 through a pipe 21 and a heater may be provided in the chamber 11 for producing steam when starting from cold. The discharge pipe 16 is surrounded by a pressure chamber 12 supplied with cooling water from a pipe 14, the water passing into the pipe 16 through an annular jet 15.

Patent GB-822271-A (GB)
Title: Improvements in or relating to the manufacture of steel
IPC: C21C5/35
Filed: 1957-10-08
Abstract: A method of producing steel by refining pig iron in a converter with bottom tuyeres comprises injecting a suspension and dephosphorizing material carried by an oxidizing gas or gaseous mixture from a nozzle above the surface of the bath, with sufficient kinetic energy to ensure that the said materials penetrate deeply into the bath, the oxidizing gas thus injected being at least 60% of the total oxygen necessary for refining. The gas blown through the bottom tuyeres has the effect of stirring the bath and may or may not be oxidizing in character. During the course of a single conversion operation the composition of the gas blown from the nozzle which may be commercially pure oxygen, and the gas blown through the bottom tuyeres, may be varied.  Conversion may be made in two or more stages in the same apparatus or in two different apparatus, with, if needed, an intermediate recarburization.  As dephosphorizing agent, lime or any other basic oxide or carbonate may be used, and to it may be added fluxing agents such as fluorspar as well as metallic oxides such as iron oxide, manganese oxide or any other substance able to lower the melting point of the slag.  The basic and/or fluxing agents may be replaced by pre-manufactured slags and the addition of dephosporizing agent may be wholly or partly made through the said nozzle during the whole or part of the conversion operation. Specification 822,270 is referred to.

Title: Improvements in fluid operated reciprocating engines
IPC: E02D7/10
Filed: 1956-10-16
Abstract: 823,982. Fluid-pressure engines; valve gear. SIMONS, C. G. Oct. 4, 1957 [Oct. 16, 1956], No. 31477/56. Classes 122 (2) and 122 (3). [Also in Groups XXI and XXVIII] A fluid-operated engine, suitable for use in pile driving, comprises a cylinder 10, Figs. 1 and 2, a piston 11 mounted on a tubular pistonrod 12 provided with a tubular extension 14, and rotatable valve means 19 within the piston by which pressure fluid may be supplied through the piston-rod to act alternately on opposite sides of the piston and exhausted through the extension 14. As shown in Fig. 2, the valve 19 is mounted within the inner end of the tubular piston-rod and seats on a washer 15 which is clamped against the piston-rod by the screwed end of the extension 14. The valve is provided, at one end, with two oppositely diverging slots 20, Fig. 10, which align in one position with two ports 16 in the piston-rod and passages 18 in the piston and at the opposite end with two similar slots 21, Fig. 11, at 90 degrees to the slots 20, which align with two further ports 16 and passages 17 in the piston. In the arrangement shown, the piston is stationary so that, when pressurized fluid, such as air, is admitted through a cross-piece 25a into the piston-rod and then through the slots 20, ports 16 and passages 18 to one side of the piston, the cylinder is moved thereby exhausting the fluid on the other side of the piston through the passages 17, ports 16 and extension 14. By rotating the valve through 90 degrees, the reverse effect is obtained, supply being through slots 20, ports 16 and passages 17 and exhaust through passages 18, ports 16 and extension 14. In an alternative arrangement, the cylinder may be stationary and the piston allowed to move. The valve may be rotated either manually or automatically through rods 22, 24 and arm 26 in the same direction or only oscillated through 90 degrees. The piston-rod may be retained against axial movement by anchoring the crosspiece 25a to a pair of fixed legs, and the movement of the cylinder transmitted by movable legs attached by bolts to nuts 28 welded to the cylinder 10. When applied to pile driving, the piston-rod is suitably anchored so that it may be advanced as the pile-driving proceeds. The cylinder may transmit its motion through a mandrel or the cylinder may itself constitute the hammer.
