Title: Giovanni Gagliardi: Innovator in Glazing Technology

Introduction

Giovanni Gagliardi is a notable inventor based in Chieti, Italy, recognized for his contributions to glazing technology. With a total of three patents to his name, Gagliardi has made significant advancements in the manufacturing processes of glass substrates and laminated vehicle glazing.

Latest Patents

Gagliardi's latest patents include a process for manufacturing a glazing and the glazing produced by this process. The glazing features a glass substrate with an enamel layer that contains 20 to 80 wt % frit and 10 to 50 wt % inorganic pigment. The enamel layer's thickness ranges from 2 µm to 50 µm, and the inorganic pigment is designed to achieve an infra-red reflectance of 37% or higher within the wavelength range of 800 nm to 2250 nm. This innovative glazing can be laminated and is suitable for use as a vehicle windscreen. The manufacturing process involves applying ink to the glass substrate, curing it to create an adhered enamel, and shaping the glass by heating it above 570°C. Preferred inorganic pigments include those of the Fe and/or Cr type in spinel, haematite, or corundum crystal forms.

Another significant patent is for laminated vehicle glazing, which consists of a first glass ply coated with an electrically conductive coating, a second glass ply, and an interlayer ply made of polyvinyl butyral. This design includes a first busbar made of conductive foil, ensuring that the electrically conductive coating is in direct contact with both the busbar and the interlayer ply. The outermost layer of the electrically conductive coating is a pyrolytically deposited transparent conductive oxide layer, preferably made of doped tin oxide. This innovation is applicable in vehicle windshields and trains with power supplies ranging from 25 V to 250 V.
