  • Publication number: 20140227212
    Abstract: A soluble UVA and/or UVB absorbing chromophore-comprising polymer useful for preparation of a sunscreen lotion has a multiplicity of repeating units where one or more of the repeating units includes at least one UVA and/or UVB absorbing chromophore. The repeating units are those formed from the ring-opening metathesis polymerization (ROMP) of a strained cycloakene, cycloalkadiene, bicycloalkene, or bicycloalkadiene, or where one or more sp3 hybridized carbons of the strained cycloakene, cycloalkadiene, bicycloalkene, or bicycloalkadiene is replaced with a heteroatom. The UVA and/or UVB absorbing chromophore-comprising polymer can be formed from a UVA and/or UVB absorbing chromophore-comprising monomer, which can be homopolymerized or copolymerized by ROMP. Alternately, the UVA and/or UVB absorbing chromophore-comprising polymer can be formed by polymerization of monomers that can subsequently be substituted with UVA and/or UVB absorbing chromophores.

  • Patent number: 8288307
    Abstract: A hydrogenation catalyst including a base material coated with a catalytic metal is made using mechanical milling techniques. The hydrogenation catalysts are used as an excellent catalyst for the dehalogenation of contaminated compounds and the remediation of other industrial compounds. Preferably, the hydrogenation catalyst is a bimetallic particle including zero-valent metal particles coated with a catalytic material. The mechanical milling technique is simpler and cheaper than previously used methods for producing hydrogenation catalysts.

  • Publication number: 20060279219
    Abstract: A collector for an electron beam tube comprises a plurality of electrode stages. The electrode stages are spaced from one another by a non-conductive spacer. The non-conductive spacer is located between portions of electrodes and extends into the collector on a first side and out of the collector on a second side. The non-conductive spacer has an inner portion extending into the collector and an outer portion extending out of the collector and a waisted portion there between. The spacer is held at the waisted portion.

  • Publication number: 20050200283
    Abstract: A linear electron beam tube comprises an electron gun having a cathode and a grid, and an anode arranged in a first portion of a drift tube. The drift tube is within a vacuum envelope and has first and second portions separated by a gap at which point an electron beam, density modulated with an input RF signal is inductively coupled to an output cavity. The vacuum envelope is partially defined by a cylindrical ceramic wall and a pair of ferromagnetic pole pieces at its ends that form a DC magnetic circuit. The pole pieces extend radially beyond the vacuum envelope. At least those parts of the surface of the pole pieces that are in the RF path are coated with a layer of relatively low RF loss material such as copper. A balance ring separates the ceramic from the pole pieces.

  • Publication number: 20050189881
    Abstract: A collector for an electron beam tube includes one or more electrode stages and has an interior surface for collection of electrons that has a surface layer of low secondary electron emission characteristic on all or part of the interior surface.

  • Patent number: 5427643
    Abstract: An adhesive tape is provided for overcoating splices in polymer coated metal tapes, which comprises a plastic film that serves as recoating material, a layer of adhesive applied to one face of this film and covered by a releasing tape which is peeled-off when required to expose the adhesive tape which is then applied onto the area of the splice to overcoat the same. The adhesive is crosslinkable by application of heat and is crosslinked during a subsequent cable jacketing operation, thereby forming a strong bond between the non-coated metal tape in the splice area and the recoating plastic film.
