Patent number: 10265931Abstract: The invention relates to a laminated glazing comprising first and second plies of glazing material, a carrier film arranged between the first and second plies of glazing material carrying an electrically conductive coating, a busbar arranged in contact with the electrically conductive coating. An edge of the carrier film is spaced inwardly from an edge of the glazing. The busbar and the carrier film are arranged to define an anchor portion suitable for anchoring the carrier film, the anchor portion comprising a region of the carrier film extending outwardly from an edge of the busbar. The anchor portion anchors the film to avoid the formation of wrinkles in the carrier film. Avoidance of wrinkles results in more uniform heating and elimination of hotspots.Type: GrantFiled: February 18, 2015Date of Patent: April 23, 2019Assignee: PILKINGTON GROUP LIMITEDInventors: Leigh Francis Mellor, Mark Andrew Chamberlain

Patent number: 10087309Abstract: The invention relates to a printed article and a feedstock for printing comprising a matrix forming material, in particular a polymeric material, and a filler material dispersed within the matrix forming material, in which the filler material comprises glass flakes. Glass flakes are characterized as having an aspect ratio of average diameter divided by average thickness greater than or equal to three. Selecting aspect ratio of glass flakes controls an orientation of glass flakes angled relative to a printed layer and formation of a depletion layer in a printed article. Technical effects of angled flakes include better adhesion between successive printed layers in 3D printing and a crack-stopping function. In a preferred embodiment the glass flakes comprise a conductive coating such that a printed article functions as a moisture sensor. Technical effects of a depletion layer include high moisture permeability and so a fast rate of change in electrical resistance due to moisture.Type: GrantFiled: November 24, 2015Date of Patent: October 2, 2018Assignees: NGF Europe Limited, Pilkington Group LimitedInventors: David Mason, James Underwood Campbell
