  • Publication number: 20180283650
    Abstract: A system for re-distributing light emitted from a light source using an optical element is described. The optical element is manufactured using a bulk matrix material, and diffusing particles and/or scattering particles are embedded within the bulk material. The optical element is coupled to the light source to capture emitted light and redistribute the light in a desired angular distribution pattern depending on the ratio of total weight of diffusing particles to total weight of scattering particles.
    Type: Application

  • Patent number: 6783719
    Abstract: A method and a system for fabricating articles made from thermoset resins using an ionic mold release agent. The invention uses a mold having a metal oxide surface with enhanced mold release characteristics. The release agent is applied internally in the resin composition or externally on the metal oxide surface. The method includes providing a mold, forming a metal oxide surface on the mold, providing an ionic release agent, providing the acid or base conjugate of the release agent at the metal oxide surface, providing a thermoset resin in the mold, and curing the resin in the mold. A method of using float glass having a SnO2 enriched surface, wherein the method includes the steps of providing an ionic release agent externally to the tin oxide surface, is also disclosed.

  • Patent number: 5163753
    Abstract: There is provided a differential thermal analysis calorimeter for performing thermal hazard testing procedures which can be utilized as an ancillary plug-in device with commercial thermal analysis data acquisition systems. Simultaneous measurement of heat flow of sample reactants and direct measurement of sample pressure is provided during a reaction within a substantially hollow furnace enclosure defining a heated zone having a heated top plate. A pair of longitudinally elongated heat conductive sample and reference tubes having upper and lower ends are each connected to the top plate adjacent their respective upper ends. The tubes depend downwardly from the top plate within the hollow furnace enclosure, and are heated by the heating means, whereby heat is conducted to the lower end of each tube longitudinally therealong. A pressure transducer is connected adjacent the upper end of the sample tube for directly measuring the pressure in the sample tube within the heated zone of the furnace.
