Title: Improvements in or relating to a process for recovering manganese values from metalliferous material containing manganese and iron
Inventor: COOPER HUGH SPENCER
IPC: C22B47/00
Filed: 1956-01-20
Abstract: Metalliferous materials such as oxide ores, steel slags and alloys containing manganese, iron and contaminants are contacted with an anhydrous chloridising gas at an elevated temperature to form and remove the manganese and iron chlorides as a gaseous stream, at least the manganese chloride being condensed and collected from said stream as an anhydrous powder and electrolysed in a fused salt bath to deposit the metal.  Chloridising gases referred to are chlorine and/or hydrogen chloride.  If desired, some or all of the iron may first be removed as ferric chloride by treatment, e.g. with chlorine at 400-650 DEG  C.; thereafter the remaining iron and the manganese may be chloridised at above 700 DEG  C., e.g. with hydrogen chloride. After condensation at e.g. 350-650 DEG  C. (or fractional condensation, if mixed chlorides are formed and if separation is desired), the electrolysis may be performed in the presence of hydrogen (see Group XXXVI), and the hydrogen chloride thereby produced returned to the chloridising process for use after the addition of chlorine (to react with excess hydrogen) and further quantities of hydrogen chloride. Similarly, excess hydrogen chloride used in the chloridisation, after removal of phosphorus chlorides and water may be reused.  By the provision of standby condensers and cells, the process may be made continuous.  Suitable initial materials are low grade ores and slags, e.g. from the open hearth steel process and containing in addition to iron and manganese, silicon dioxide, calcium, aluminum and magnesium oxides and phosphorus and carbon, high grade ores and high carbon ferromanganese.  If metals other than iron and manganese are present as oxides the absence of a reducing agent such as carbon may be essential, depending upon the particular metals.  Specification 713,432, [Group XXXVI], is referred to.

Title: Improvements in or relating to methods of manufacturing frame grids for use in electronic valves
IPC: C23C18/28
Filed: 1963-01-16
Abstract: A method of manufacturing a frame grid, having a grid wire wound on a frame, for use in an electronic valve, comprises coating the frame with a phosphorus-containing nickel layer by means of an electroless Ni plating bath of an aqueous solution containing Ni ions, hypophosphite ions and a compound forming a complex with Ni ions, in which solution the mol. ratio between the hypophosphite ions and the Ni ions is at least 3 and the mol. ratio between the compound forming complexes with the Ni ions and the Ni ions is at least 2, the bath having a pH between 4 and 7, thereafter winding the grid wire on the frame and then heating the assembly at 700-800  DEG C.  Specified complex forming compounds are citric and hydroxyacetic acids.  The bath may contain a buffer to maintain the pH constant formed on the basis of an amine. Ethylene diamine, ammonium ions and aminoacetic acid serve both as Ni complexing compounds and as buffers.  W wire and frames of Mo or Fe-Ni-Co are referred to.  The P content in the deposited Ni depends on the quantity of complex forming compound relative to that of the Ni ions. In an example, baths containing sodium hypophosphite, citric acid and different quantities of Ni ions deposit Ni containing 8%, 9%, 11.5%, 14.5% and 20% of P, the first two values being produced from baths outside the scope of the method as defined above.  A specific plating solution contains per litre 16 gs. NiCl26H2O, 80 gs. amino-acetic acid, 24 gs. NaH2PO2.H2O and 6.8 gs. NaOH.  The pH of the solution is 5.5.  The mol. ratio between the hypophosphite ions and the Ni ions is 3.3 and the ratio between the compound forming complexes with the Ni ions and the Ni ions is 15.8. Plating may be at 65  DEG C.  A large number of frames may be plated in a rotating drum.  The Ni applied may be 2-5 microns thick. Specification 785,695 is referred to.
