20140209533 | MULTILAYER, MICRO- AND NANOPOROUS MEMBRANES WITH CONTROLLED PORE SIZES FOR WATER SEPARATION AND METHOD OF MANUFACTURING THEREOF - The present invention relates to design and manufacture of multilayer sintered membranes made from metals and inorganic compounds (ceramics, silicate, clay, zeolites, phosphates, etc.). The membranes are designated for separation of water. They comprise at least one layer having nanopores commensurable with the size of water molecules. The membranes comprise: (a) supporting metallic layer having pore size 1-500 microns, (b) metallic interlayer having pore size <2 micron, (c) sublayer with local regular protrusions of the interlayer into the supporting layer to increase service life of the membrane, and (d) one nanoporous ceramic or metallic top layer having pore size in the range of 1-15 angstroms. The invented design and method allow the manufacture of cost-effective multilayer membranes containing nanoporous layer with controlled pore sizes in each layer and optimal morphology of pores that provides selective transport of molecules during filtration and separation of liquids. | 07-31-2014 |
20130315773 | Method of Manufacturing Pure Titanium Hydride Powder and Alloyed Titanium Hydride Powders By Combined Hydrogen-Magnesium Reduction of Metal Halides - The invention relates to energy-saving manufacturing of purified hydrogenated titanium powders or alloying titanium hydride powders, by metallo-thermic reduction of titanium chlorides, including their hydrogenation, vacuum separation of titanium hydride sponge block from magnesium and magnesium chlorides, followed by crushing, grinding, and sintering of said block without need for hydrometallurgical treatment of the produced powders. | 11-28-2013 |
