20100210754 | X-ray Opaque Barium-Free Glasses and Uses Thereof - Zirconium-containing BaO— and PbO-free X-ray opaque glasses having a refractive index n | 08-19-2010 |
20100210755 | X-ray Opaque Barium-Free Glasses and Uses Thereof - Zirconium-containing BaO- and PbO-free X-ray opaque glasses having a refractive index n | 08-19-2010 |
20100212742 | PHOTOVOLTAIC DEVICE WITH CONCENTRATOR OPTICS - The invention relates to a photovoltaic device having a concentrator optics. The photovoltaic device includes at least one solar cell and a concentrator optics, with the concentrator optics having at least one first, light-input-side, focusing optical element and at least one second optical element downstream of the first, light-input-side optical element and upstream of the solar cell, onto which, in operating position of the photovoltaic device, the bundled solar radiation falls by way of the first optical element, with the second optical element having a solarization-stabilized silicate glass. | 08-26-2010 |
20100242543 | METHOD AND SYSTEM FOR PRODUCING GLASS, IN WHICH CHEMICAL REDUCTION OF GLASS COMPONENTS IS AVOIDED - In the apparatus for producing glass reduction of reduction-sensitive components in the glass melt is reduced or preferably is prevented during the melting and/or fining processes by introducing an oxidizing agent into the glass melt. The apparatus has a melt crucible, a fining vessel, and a device for conducting oxygen and/or ozone into the glass melt in the melt crucible and/or fining vessel, in order to suppress reduction of reduction-sensitive components of the glass melt. A preferred embodiment of the apparatus has a metallic skull crucible, which includes the melt crucible and/or the fining vessel. The apparatus preferably includes a homogenization unit connected to the fining vessel to receive glass melt from the fining vessel in order to further process the glass melt after refining. | 09-30-2010 |
20110103757 | SIDE-EMITTING STEP INDEX FIBER - Side-emitting step index fibers. Between core and cladding, the side-emitting step index fibers have scattering centers that ensure the coupling out of light from the fiber. The side-emitting step index fibers are produced by preforms that contain inlay rods, in which the scattering centers are embedded and which are applied to the outer region of the fiber core during fiber drawing. Alternatively, at least one inlay tube can be used. | 05-05-2011 |
20110218268 | X-ray Opaque Barium-Free Glasses and Uses Thereof - Zirconium-containing BaO- and PbO-free X-ray opaque glasses having a refractive index n | 09-08-2011 |
20120057337 | CONVERSION MATERIAL, PARTICULARLY FOR A WHITE OR COLORED LIGHT SOUCE COMPRISING A SEMICONDUCTOR LIGHT SOURCE, A METHOD FOR THE PRODUCTION THEREOF, AS WELL AS A LIGHT SOURCE COMPRISING SAID CONVERSION MATERIAL - The invention relates to a conversion material, in particular for a white or colored light source comprising a semiconductor light source as primary light source, comprising a matrix glass that, as bulk material, for a thickness d of about 1 mm, has a pure transmission τ | 03-08-2012 |
20140106168 | X-RAY-OPAQUE BARIUM-FREE GLASS AND USES THEREOF, ESPECIALLY IN POLYMER-BASED DENTAL COMPOSITIONS - The X-ray-opaque glass, which is free of BaO and PbO except for at most impurities, has a refractive index n | 04-17-2014 |
