Title: Method for electrochemical enrichment of low quality raw manganese
Inventor: SHENGELIA (GE) JEMAL
IPC: C22C1/06
Filed: 2020-11-10
Abstract: A method for electrochemical enrichment of low quality raw manganese provides electrochemical discharge of raw material by electrolysis with indirect electrochemical reduction of raw MnO2 and parallel reduction of Fe3+ to Fe2+ ions in the electrolyzer by electrolytic manganese diode at the anode – electrosynthesis; in addition, usage of large electrolyzer, and the electrode passing through the carbon cage is taken as a cathode. The concentration of iron ions in the solution is 1.5-2.5 g/l, and the solution passed through the cathode is delivered from the electrolyzer to the accumulation of raw manganese, and the solution obtained by leaching into the mass is returned to the anodic area of electrolyzer without filtering.

The resultant Y2O3 partially stabilized zirconia ceramics have a Y2O3 content of from 1.3 mol.% to 2.0 mol.%, the content of the tetragonal phase being 65% or more, and is a high strength ceramic having a fracture toughness of more than 10 MN/m3/2, reaching 16 MN/m3/2.  The resultant alumina containing partially stabilized zirconia ceramic has a novel composition containing transition metal ozide, and is a high strength ceramic having Vickers hardness of 1100 to 1600 Kg/mm2, and improved heat shock resistance.  Particularly, when based on the above-mentioned Y2O3 partially stabilized zirconia, the fracture toughness will reach 18.5 MN/m3/2.

Abstract: ABSTRACT A scanner including a source of coherent or substantially coherent radiation, a radial hologon, a f.THETA. lens and a target.  Between the light source and the hologon there are means for forming radiation from the source into a collimated beam having an oblong cross-sectional shape and for directing the beam onto the hologon at a predetermined incident angle and with the long axis of the oblong cross-sectional shape of the beam radial of the axis of rotation of the hologon.  Two prisms are provided between the hologon and the lens means for so modifying the cross-sectional shape of the beam that the spot at the target station has a selected shape and orientation.  The prisms are mounted in an articulated mount having adjustment means, which allows rotation of the prisms so as to correct both bow in the scan line and incorrect placement of the scan line on the target.  Such bow and incorrect placement could be created by a change of the wavelength of the radiation and by the pitch of the grating lines of the hologon being different to nominal.
