  • Patent number: 6013752
    Abstract: Halogenated resin compositions are prepared without using halogen acids by combining at least one silicone intermediate, with an optional silane, an organic halogen-containing ingredient having functional groups selected from the group consisting of hydroxy, amine, and carboxyl groups, and a resin selected from the group consisting of hydroxy- and epoxy-functional resins. One or more amine curing agent and/or catalyst selected from the group consisting of organometallic compounds, acids, bases, and mixtures thereof can optionally be added to facilitate ambient temperature curing of the resulting composition. The combined ingredients undergo hydrolysis reactions to form a halogenated organooxysilane that condenses to form a cross-linked halogenated polysiloxane composition. The resin also reacts with the condensing halogenated organooxysilane to introduce itself into the cross-linked halogenated polysiloxane and, thereby form the halogenated polysiloxane resin composition.

  • Patent number: 6010796
    Abstract: An organic electroluminescent device of a single heterostructure is fabricated by forming a transparent electrode (anode) of ITO, a hole transport layer, an electron transport layer and a metal electrode (cathode) in that order on a glass substrate. An exciton generation promoting layer is formed between the hole transport layer and the electron transport layer. The hole transport layer is a two-layer structure consisting of a hole transport light emitting layer or a hole injection layer, and a hole transport light emitting layer. Exciton generation in the hole transport light emitting layers 4a and 4b can be promoted. The hole injection layer enables efficient hole injection.

  • Patent number: 6004682
    Abstract: An oriented polymeric in-mold label film comprises a hot-stretched, annealed, linerless self-wound film lamina and has a face layer for printing and a base layer which includes a heat-activatable adhesive. The heat-shrinkability of the film is balanced thickness-wise to minimize curl and allow the film to be printed in conventional label-printing presses. An antistat may be included only in the charge for the base layer which includes the heat-activatable adhesive. In the manufacture of labelled blow-molded containers, sheets and labels formed from the film may be handled at high speeds while maintaining accurate registration and dimensional and positional integrity even in the absence of any reinforcing backing, yet the labels perform well on deformable containers such as shampoo bottles.

  • Patent number: 5989684
    Abstract: A slitting and scoring machine includes an upper tooling roller and a lower tooling roller that cooperate to define a tooling nip. Each tooling roller includes an alternating series of coaxially arranged annular knives, annular dies, and annular mandrels. A web of insulation is drawn through the tooling nip to simultaneously (i) cut the web into strips, (ii) score the strips in a manner that promotes the forming of the strips, and (iii) partially form the strips into modified U-shapes. Each strip includes a longitudinally extending middle segment and a pair of longitudinally extending side segments that extend away from the middle segment in a divergent manner to define a longitudinally extending channel. Longitudinally extending grooves are formed by the scoring at the junctures of the middle segment and the side segments. The scoring/grooves promote the divergent shape of the strip.

  • Patent number: 5972271
    Abstract: A modified bitumen sheet material and method for a protective moisture barrier, particularly for masonry surfaces. The sheet material has a bitumen layer modified by the addition of a minor amount of a long-chain polybutadiene-isocyanate urethane polymer and optionally, a modifying amount of a hydrocarbon oil to provide a stable, non-flow and selected tackified surface properties to the bitumen layer. The sheet material includes a releasable casting paper film on one surface of the bitumen layer, to be removed prior to use, and a cross-linked polyethylene film bonded to the other outer surface of the bitumen layer as a handling or moisture barrier sheet. The sheet material is prepared by casting the hot, melted bitumen as a layer onto a casting paper sheet and applying the outer film to the exposed bitumen surface to bond to the top surface.
