Patent number: 10596787Abstract: A laminated glazing comprises two plies of glass having an interlayer structure laminated therebetween. The interlayer structure comprises a first sheet of an interlayer material framing a suspended particle device film incorporated therein. The interlayer material is chosen to minimize the migration of the components of the interlayer material into the suspended particle device film. Preferably, the interlayer material does not contain plasticizers, or contains a plasticizer which does not diffuse into the suspended particle device film structure.Type: GrantFiled: April 20, 2007Date of Patent: March 24, 2020Assignees: PILKINGTON GROUP LIMITED, PILKINGTON AUTOMOTIVE LIMITEDInventors: Michael Robert Greenall, Ashley Carl Torr, Jonathan Peter Voss

Patent number: 8957124Abstract: A laser can be used to modify a glazing 100, 300 so as to improve its suitability for use with a signal-receiving device 350 or a signal-transmitting device 350. This is done by using the laser to provide a region of reduced opacity 110, 202, 340 to the signal within the glazing. Preferably, the laser is be used to reduce the opacity of a selected region 340 of a tinted interlayer in situ. The glazing may be for a vehicle, especially an automotive vehicle.Type: GrantFiled: January 6, 2006Date of Patent: February 17, 2015Assignee: Pilkington Group LimitedInventors: Michael Lyon, Michael Robert Greenall

Patent number: 7722948Abstract: A laminated glazing comprising two panes of glazing material, a sheet of interlayer material extending therebetween, and an electrically conductive member formed (possibly etched) from a sheet of electrically conductive material also positioned between the panes. The electrically conductive member may function as one or more of: an antenna element, a capacitive sensor, an electromagnetic shield, part of alarm circuitry, a resistance thermometer, a busbar. Also a method of manufacturing such a glazing involving locating a pre-formed electrically conductive member and a sheet of interlayer material on a first pane of glazing material, placing a second pane of glazing material in register with the first so that the electrically conductive member and the interlayer material are between the two panes, and laminating in an autoclave.Type: GrantFiled: October 5, 2006Date of Patent: May 25, 2010Assignee: Pilkington Group LimitedInventors: Jonathan Barclay Dixon, Michael Robert Greenall

Publication number: 20090279004Abstract: A laminated glazing comprises two plies of glass having an interlayer structure laminated therebetween. The interlayer structure comprises a first sheet of an interlayer material framing a liquid crystal film incorporated therein. Preferably, the interlayer material does not contain plasticizers, or contains a plasticizer which does not diffuse into the liquid crystal film structure. In addition, the interlayer material preferably resists the migration of mobile liquid crystal film components.Type: ApplicationFiled: April 20, 2007Publication date: November 12, 2009Applicants: PILKINGTON GROUP LIMITED, PILKINGTON AUTOMOTIVE LIMITEDInventors: Michael Robert Greenall, Ashley Carl Torr, Jonathan Peter Voss
