20090025425 | Method for spray-forming melts of glass and glass-ceramic compositions - The invention relates to a process and apparatus for forming a particulate composition, especially a particle glass composition, through the use of shock waves. A nozzle element is utilized having inlets for introduction of cold and heated gas and a delivery tube for introducing molten material. Through the introduction of the cold and heated gases, droplets are formed from a molten stream, a cone-shaped standing shock wave is formed, and shock waves are formed via a modified Hartmann-Sprenger chamber, the shock waves impinging on the droplet stream to break up the larger droplets. | 01-29-2009 |
20120033693 | REAR EARTH ALUMINOBOROSILICATE GLASS COMPOSITION - The invention relates to aluminoborosilicate-based glasses suitable for use as a solid laser medium. In particular, these aluminoborosilicate-based laser glasses exhibit broad emission bandwidths of rare earth lasing ions. Although not entirely understood, the broadening of the emission bandwidth is believed to be achieved by the presence of significant amounts of lanthanide ions in the glass matrix. In addition, because of the high values of Young's modulus, fracture toughness and hardness, the rare earth aluminoborosilicate glass system according to the invention is also suitable as transparent armor window material. | 02-09-2012 |
20120269995 | LIGHT WEIGHT TEMPERATURE RESISTANT TRANSPARENT LAMINATE STRUCTURE - A transparent laminate structure is provided that includes a front section, a rear section, and a middle section securing the front and rear sections to one another with a gap therebetween. The front section has a strike face formed of an impact resistant layer and a polymer backing layer bonded to the impact resistant layer by an interlayer.
