Patent application number | Title | Published |
20130128912 | CRUCIBLE HAVING A POLYGONAL OPENING - The invention relates to an arc melted silica crucible having a polygonal opening, in particular square or rectangular, and its method of fabrication, which comprises preforming the silica powder in a hollow mold having a polygonal opening, said mold being provided with a multiplicity of channels passing through its bottom and its walls, said channels being distributed over its whole internal surface, to constitute a preform, then melting the silica by an electric arc inside the preform, sucking the gases through the mold and the preform, generating a gas speed of at least 0.15 m/second at every point of the inner surface of the preform at the onset of the melting. | 05-23-2013 |
20130052113 | METHOD AND DEVICE FOR THE PURIFICATION OF THE AIR - The invention relates to a method and a device for the purification of air by passing a flow of the air through a filter having a photocatalytic action subjected to UV lighting, said filter comprising a felt of mineral fibers, the fibers of which are coated with a material having a photocatalytic action, the residence time of the air in contact with the filter being greater than 70 msec and the UV lighting having a power of less than 35 mW per cm | 02-28-2013 |
20120171420 | GLASS FOR INSULATING COMPOSITION - The invention relates to a composition comprising mica and glass, said glass comprising:

20120063958 | MEDIA FOR PHOTOCATALYTIC FILTER - The invention relates to a filtering media having a photocatalytic action which has a thickness of at least 2 mm, which is homogeneous and which is devoid of orifice apparent to the naked eye, comprising a felt of inorganic fibers, the fibers of which are coated with a coating comprising a catalyst having a photocatalytic action, said felt exhibiting a weight per unit area of between 30 and 80 g/m | 03-15-2012 |
20110186418 | PARTICULATE FILTER HAVING MINERAL FILTER MEDIA - The invention relates to a particulate filter comprising a cartridge and a filter media placed in the cartridge in the prefiltering position, said filter media being essentially mineral. Thanks to the absence of any organic compound, the filter media generates no volatile organic compound. The filter media may also be of the type having a photocatalytic action. | 08-04-2011 |
20110064638 | PURIFIER COMPRISING A PHOTOCATALYTIC FILTER - The invention relates to a gas purifier comprising a filtering media having a photocatalytic action, a system for illuminating said media with UV radiation, a time-delay means or a volatile organic compound analyzer, and a means for automatically adjusting the speed of the gas passing through it or for adjusting the intensity of the UV illumination, said adjusting being carried out as a function of the time determined by the time-delay means or as a function of the content of a volatile organic compound analyzed by the analyzer. The invention also relates to a process for the purification of gas using a purifier comprising a filtering media having a photocatalytic action and a system for illuminating said media with UV radiation, according to which, when the concentration of a compound in the gas is greater than a value V | 03-17-2011 |
