  • Patent number: 8931885
    Abstract: A composition is made from ingredients comprising a fluorinated polyurethane and a copolymer of (i) a fluoroalkylene monomer unit and (ii) a dioxole monomer unit substituted with at least one substituent selected from the group consisting of a fluorine atom and a fluoroalkyl. The fluorinated polyurethane is a product of an isocyanate and a hydroxyl functionalized fluorinated polyether. The composition can be employed for making anti-wetting coatings used, for example, in printhead devices.

  • Patent number: 8906190
    Abstract: A system and apparatus are provided for adhering steering ribs to an intermediate transfer belt (ITB). These steering ribs (one or more) are applied to the ITB by placing the rib material around a cylindrical fixture. The rib material is held in place by a vacuum that is applied to the rib material to hold it against the fixture. An ITB may be separately held in place on the fixture by another vacuum until the rib material is adhered to the inside surface of the ITB through application of compressed air to force the rib material outward against the ITB. Once the rib material is adhered to the ITB, a series of apertures directs compressed air against the rib and the ITB to release them from the fixture.
