Title: Improvements in and relating to lead presses
IPC: B21C33/02
Filed: 1939-07-03
Abstract: 531,617. Squirting. BRITISH THOMSONHOUSTON CO., Ltd. July 3, 1939, No. 19314. Convention date, July 2, 1938. [Class 83 (iv)] To avoid the inclusion of any oxide in the lead &c. in the pressure cylinder 10 of an extrusion press, for sheathing cables or making pipes, the lead is introduced by a removable tube 27, which extends nearly to the residual charge 54, until it overflows the top of the cylinder where it is retained by a flooding ring 38 with ribs 39, Fig. 9. Before the ram 12 is withdrawn, for the new charge, hydrogen flames are projected around it by half-ring burners 64 and, afterwards, additional flames, from a burner 66, are projected into the cylinder. The tube 27 is then swung, by a wheel 34, arm 31 and pin-and-slot connection 32, from position A to B and connected, by a clamp operated by a wheel 50, to a pipe 26 which extends from a pot 16 containing lead at 400 ‹ to 410 ‹C. The pot contains two closed chambers 17, 19, the first being supplied with steam or gas, inert to lead, under pressure to cause the lead to rise in the chamber 19, which is supplied with inert gas at 23 or 24a or both, and overflow into the pipes 26, 27 which are already discharging the gas into the cylinder 10. When the lead overflows into the ring 38, the supply is stopped, the pipe 27 is disconnected and returned to the position A, the dross is skimmed off, the burners 66, 64 are swung out of the way and the ram lowered into the cylinder. The flash 40, Fig. 7, forced out by the ram, lifts the lead overflow which has solidified into three easilyremovable slabs 41. The pipe 27 has a nozzle 29 adapted to give a rotary motion to the lead in the cylinder. To prevent air from entering the pipe 26, when the pipe 27 is detached, a cap is clamped in its place. The pipe 27 is jointed at 28 to facilitate cleaning. In a modification, the pot has a bottom exit and is adapted to receive inert gas under pressure to force the lead out.

Patent GB-1186204-A (GB)
Title: Flotation of Metallic Oxides.
Inventor: WESTON DAVID
IPC: B03D1/001
Filed: 1967-04-28
Abstract: 1,186,204. Froth flotation. D. WESTON. 28 April, 1967 [13 May, 1966; 18 May, 1966; 11 July, 1966], No. 19645/67. Heading B2H. In a process for the separation of metallic oxides from metallic oxide-containing materials by froth flotation, without the need for any desliming prior to flotation, a pulp containing the material in effectively dispersed state is treated with a collecting agent to effect activation of the metallic oxide values of the material. The pulp is conditioned at an ap- ,propriate pH to initiate flocculation of the metallic oxide values. The pH of the resulting pulp is then adjusted to a value suitable for further flocculation and for flotation of the metallic oxide values and is conditioned at the adjusted pH value to effect further flocculation of the metallic oxide values and dispersion of the gangue of the material in the pulp. The pulp is then finally subjected to a flotation process to recover the metallic oxides. The initial effective dispersion may be achieved without the addition of a dispersing agent over a range of pH's and conditioning times. Alternatively, dispersion requires careful control of pH, conditioning time and addition of a dispersing agent, e.g. sodium silicate, sodium hydroxide, lignin sulphonate or silicon tetrachloride. Where initial dispersion is carried at an alkaline pH, recovery of the metallic oxides is improved by the addition of an electrolyte, e.g. sodium fluoride, sodium sulphate or sodium chloride. Suitable collecting agents include fatty acids or the combination of a fatty acid with petroleum sulphonate and/or fuel oil, the fuel oil acting as a modifying agent. PH adjusters may include sulphuric acid, sodium silicate or sodium hydroxide. The flotation circuit may consist of a rougher stage followed by a number of cleaning stages either without or with conditioning between some or each of the stages using a dispersing agent. Carbonates which tend to float with the metallic oxides in the later stages of cleaning may be depressed by lowering the pH of the pulp to acid and conditioning with sodium fluoride. Where a wet grinding circuit precedes the flotation circuit, the dispersing agent and/or the collecting agent may be added directly to the grinding circuit. A wetting agent may be added to the pulp in the grinding circuit. Examples of four-stage conditioning cycles and of comparative tests carried out on iron ores and uranuim ores are given. The process is also applicable to the treatment of materials already in comminuted or naturally finely divided condition, e.g. tailings, slimes, beach sands or clays containing, for example, vanadium oxides.

Abstract: 147,847. Ges. f³r drahtlose Telegraphie. Jan. 19, 1915, [Convention date]. Void [Published under Sect. 91 of the Act]. Drawings to Specification. Inductor-alternators.-In a high-frequency alternator, particularly of the homopolar inductor type, sections of the armature are connected in parallel, so that the thickness of the insulation and of the polar gap may safely be reduced and the self-inductance of the machine is lessenned. The current thus obtained is stepped up in voltage by a transformer dimensioned to suit the aerial or frequency-transformer for use with which the apparatus is designed. The low self-inductance obviates the necessity of interposing condensers in the windings.
