  • Patent number: 9108368
    Abstract: There is described an apparatus and method for transporting contact lenses through dipping baths (2, 3, 4) for e.g. rinsing, extraction, coating or loading purposes. The lenses are individually accommodated in respective containers (5) which are capable of enabling a flow of treatment fluid (S) into and out of the container (5). During their automatic transport through the dipping baths (2, 3, 4) the containers (5) are held in carriers (6). Lifters (9) are provided for automatically lowering and raising the carriers (6) in a reciprocating manner along their travel through the dipping bath (2, 3, 4). The reciprocating lowering and raising of the containers (5) is accomplished such, that a portion of each container which accommodates a contact lens remains immersed in the treatment fluid (S) which is contained in the dipping bath (2, 3, 4) while the container (5) suspended from the carrier (6) is advanced through the dipping bath (2, 3, 4) from a starting end to a leaving end thereof.

  • Patent number: 9017773
    Abstract: A method is described for depositing nanostructures, such as nanostructures of conducting polymers, carbon nanostructures, or combinations thereof. The process comprises placing the nanostructures in a liquid composition comprising an immiscible combination of aqueous phase and an organic phase. The mixture is mixed for a period of time sufficient to form an emulsion and then allowed to stand undisturbed so that the phases are allowed to separate. As a result the nanostructure materials locate at the interface of the forming phases and are uniformly dispersed along that interface. A film of the nanostructure materials will then form on a substrate intersecting the interface, said substrate having been placed in the mixture before the phases are allowed to settle and separate.

    Abstract: Systems and methods for fabricating multi-functional articles comprised of additively formed gradient materials are provided. The fabrication of multi-functional articles using the additive deposition of gradient alloys represents a paradigm shift from the traditional way that metal alloys and metal/metal alloy parts are fabricated. Since a gradient alloy that transitions from one metal to a different metal cannot be fabricated through any conventional metallurgy techniques, the technique presents many applications. Moreover, the embodiments described identify a broad range of properties and applications.

  • Patent number: 8486533
    Abstract: An apparatus includes an electronic component mounted on a substrate and metal conductors electrically connecting the electronic component. A conformal coating overlies the metal conductors and comprises a polymer into which a phosphine compound is impregnated and/or covalently bonded. Accordingly, the conformal coating is able to protect the metal conductors from corrosion caused by sulfur components (e.g., elemental sulfur, hydrogen sulfide, and/or sulfur oxides) in the air. That is, the phosphine compound in the polymer reacts with any corrosion inducing sulfur component in the air and prevents the sulfur component from reacting with the underlying metal conductors. Preferably, the phosphine compound in the polymer does not react with other components in the air (e.g., carbon dioxide) which would otherwise deplete its availability for the target reaction. The phosphine compound may be rendered completely non-volatile by covalently bonding it directly into the polymer backbone.
