LAMINATED GLASS Russian patent published in 2022 - IPC C03C27/12 H05B3/86 

FIELD: glass industry.

SUBSTANCE: invention relates to laminated glass. Laminated glass contains a pair of glass plates facing each other; an intermediate layer located between this pair of glass plates; and a set of parallel linear elements for heating the transparent area of this pair of glass plates. Each of the set of linear elements has a line width greater than or equal to 2 microns and less than or equal to 30 microns. At least part of the set of linear elements have a non-constant line width. The set of linear elements includes linear elements having line widths that differ from each other. Among the linear elements inside a square with a side of 50 mm in any position in the area where the linear elements are located, when the line width of any of the linear elements is designated as W_i [mcm] and the line width of its adjacent linear element as W_i+1 [mcm], the maximum value |W_i-W_i+1|_max among the absolute values of the differences between W_i and W_i+1 are in the range of 1 mcm < |W_i-W_i+1|_max < 10 mcm, and the standard deviation of the line width of the set of linear elements is more than 0.5 mcm.

EFFECT: creation of laminated glass, which can suppress optical effects due to diffracted light caused by linear elements.
