  • Patent number: 10526243
    Abstract: Bird collisions with windows or other glazings are minimized or prevented with a glazing comprising as least one substrate with a UV reflectance coating deposited over the substrate in a patterned arrangement comprised of a plurality of stripes, and each of the plurality of stripes has a thickness that changes by 10 nm or less over every 1 mm in width. Such an arrangement of stripes having soft edges are less apparent, and thus more aesthetically pleasing, when compared with a similar arrangement of stripes formed with hard edges, while providing an effective deterrent to bird collisions. The glazing may also be utilized as part of a laminated glazing or insulated glazing unit. A method of manufacturing the glazing is also provided.

  • Patent number: 10345229
    Abstract: A method of determining the concentration of a species in a portion of a furnace atmosphere is described. The method comprises the steps of measuring first, second and third intensities of electromagnetic radiation in the furnace at first, second and third wavelengths respectively. The third wavelength is selected to be representative of absorption of electromagnetic radiation by the species. A fourth intensity of electromagnetic radiation is calculated, being an estimate of the intensity of electromagnetic radiation in the furnace at the third wavelength absent any absorbing species in the furnace atmosphere. The third intensity and the fourth intensities are used to determine a parameter that is proportional to the concentration of absorbing species in the portion of the furnace atmosphere. Apparatus for carrying out the method is also described.
