PRIME SUBSTANCE AND PROCESSES FOR THE MANUFACTURE OF OPTIC FILTERS IN THE VIOLET AND VISIBLE EXTREME REGION
NOVELTY – The ultraviolet and visible region optical filter fabrication material comprises, e.g., SiO2, CaO, Al2O3, Fe2O3, Na2O, K2O, TiO2 and MgO, which form a ceramic matrix. USE – In optical filters production. DETAILED DESCRIPTION – An INDEPENDENT CLAIM is given for a process for making the filter. The process eliminates surface porosity of the matrix by using processed hospital waste plasma, with controlled cooling.
Main Application Field
L03 (Electro-(in)organic – chemical features of conductors, resistors, magnets, capacitors and switches, electric discharge lamps, semiconductor and other materials, batteries, accumulators and thermoelectric devices, including fuel cells, magnetic recording media, radiation emission devices, liquid crystals and basic electric elements. Growing of single crystals of semiconductors and their doping are included, but semiconductor devices, where the manufacture is not claimed are excluded. Electrography, electrophotography, magnetography, electrolysis, electrophoresis, power plant, X-ray and plasma-techniques, ion exchange resins, polyelectrolytes, electroplating, metal electrodeposition, electroforming, anodising, electrolytic cleaning, cathodic protection and electrolytic or electrothermic production or refining of metals are all covered elsewhere (Sections G, J, K and M).); L02 (Refractories, ceramics, cement – includes manufacturing methods, limes, soil preparation for (road) building, magnesias and slags, cements, mortars, concretes, abrasives, thermal or acoustic insulation (non)oxide ceramics and ceramic composites, but not brick making, concrete mixers or casting or potters’ wheels (C04).); P81 (Optics (G02).); V07 (Fibre-optics and Light Control)
