  • Publication number: 20200147935
    Abstract: A laminated glazing for use as a combiner in a head up display comprises first and second glazing panes with at least one adhesive ply and an infrared reflecting film therebetween. Light incident upon the first glazing pane at an angle of incidence of 60° is reflected off the laminated glazing to produce first, second and third reflections, the third reflection being from light reflected from the infrared reflecting film. The laminated glazing further comprises light intensity reducing means between the first and second glazing panes for reducing the intensity of the third reflection. In an aspect, upon directing a beam of electromagnetic radiation having an intensity IO at 770 nm toward the first pane of glazing material at an angle of incidence of 60°, the intensity of the third reflection at a wavelength of 770 nm is less than or equal to 0.185×IO.

  • Publication number: 20200140324
    Abstract: A method for coating glass containers provides improved tensile strength (hence improved resistance to internal pressure). The coatings so produced are durable and, in particular, resistant to the treatment steps associated with recycling of bottles. The method lends itself in particular to implementation as part of a continuous production process by utilising residual heat from the bottle casting step. The ability to recycle and the use of residual heat from an existing process offer considerable environmental benefits.
