  • Patent number: 9193135
    Abstract: A laminated glazing comprising an SPD ply comprising a suspended particle device having a low light transmission off-state and a high light transmission on-state, at least one interlayer ply comprising an interlayer material, and at least one glazing ply is disclosed. The interlayer material has been dried to a predetermined moisture content to increase the time over which the suspended particle device is switchable between the low light transmission off-state and the high light transmission on-state. Use of a dried interlayer to increase the time over which an SPD film is switchable between a low light transmission off-state and a high light transmission on-state is also disclosed. Additionally a process for producing the aforementioned laminated glazing is disclosed. It has been found that the moisture content of the interlayer material is a factor in determining the switching characteristics over time of an SPD film incorporated into a laminated glazing.

  • Publication number: 20070262082
    Abstract: A bag dispenser including an enclosure having sidewalls for enclosing a plurality of serially connected bags. The dispenser has a gripping orifice in a sidewall of the enclosure through which a first bag extends, and through which a serially connected second bag extends at least partially. In operation, the gripping orifice grippingly engages the second bag, or the first bag, for holding the gripped bag in the gripping orifice and suspending the first bag from the gripping orifice. When the user is finished with the bag, it can be removed from the bags remaining in the enclosure, closed and discarded.
