  • Publication number: 20120236393
    Abstract: A suspended particle device (SPD) film or laminate thereof. The film includes substrates coated on their inner surface with a polythiophene-based conductive polymer serving as electrode means. The polymer may be applied in the form of an aqueous composition also comprising solvent(s) and binder(s). A preferred polymer is a polyethylene dioxythiophene (PEDT) polymer. The polymer may be doped with polystyrene sulfonate. The polymer may be connected to a conductive material that extends beyond an outer boundary of the film to connect with a voltage source. Adhesive strength between the cured emulsion and the polymer is at least 1.46 N/25 mm. A further aspect constitutes a method for increasing adhesion between a cured suspended particle device emulsion and electrode means in a light valve film. The method comprises applying the polymer on an inner surface of the substrates constituting the film to serve as the electrode means.

  • Patent number: 4846587
    Abstract: A bag comprised of flaccid material and having an improved integrally formed carrying handle which supports the weight of one or more articles contained within the bag with minimal discomfort to the supporting portion or portions of the user's body. The bag includes an uppermost flap containing the improved integrally formed carrying handle. The handle is provided by making a continuous curvilinear slit in the flap, the ends of the slit comprising a pair of inwardly. open arcs. The uppermost ends of the inwardly open arcs are inwardly extended until they transition into a centrally located, upwardly concave arc which connects the two inwardly open arcs to one another.
