    摘要: A three part laminated material for use in making blister packages and a method of making such a material. The material is comprised of a central core layer of fluoro-polymer based sheet material to each side of which a separate polymer film is adhesively attached. In the preferred embodiment, each of the polymer films is polyvinyl chloride, although a variety of chemically different films may be used. The disclosed material provides a high moisture barrier, a stable inter-laminar structure and outer surfaces which lend themselves well to bonding with other materials.

    摘要: A welding material assembly is constructed and arranged to position a welding material in electrically conductive relation between exterior surface portions of first and second weldable members at a location where the first and second weldable members are to be joined. The welding material assembly includes at least one welding material member mounted on a flexible carrier sheet in a predetermined arrangement, each welding material member being constructed of an electrically conductive metallic welding material capable of melting when heated by application of an electrical current and each carrier sheet being constructed of a material that is electrically nonconductive. Each welding material member is mounted on the sheet such that when the sheet is placed between the exterior surfaces of said first and second weldable members to be welded each said welding material member is electrically conductively disposed therebetween.

    摘要: This invention is a regenerable process for producing elemental sulfur from SO.sub.2 initially contained in a dilute gas source by: (1) absorbing the SO.sub.2 in a concentrated Na.sub.2 SO.sub.3 solution to convert most of the Na.sub.2 SO.sub.3 to Na.sub.2 S.sub.2 O.sub.5 ; (2) separating one third of the absorbed SO.sub.2 ; (3) reacting the residual mixture with solid NaHCO.sub.3 to form gaseous carbon dioxide used in a subsequent step and a slurry composed of solid Na.sub.2 SO.sub.3 suspended in a Na.sub.2 SO.sub.3 solution; (4) separating solid Na.sub.2 SO.sub.3 from the solution which is recycled to (1) above; (5) reducing solid Na.sub.2 SO.sub.3 to Na.sub.2 S; (6) reacting the Na.sub.2 S with H.sub.2 O and CO.sub.2 to form solid NaHCO.sub.3 which is recycled to (3) above and gaseous H.sub.2 S; (6) reacting gaseous H.sub.2 S with SO.sub.2 separated in (2) above to form water and elemental sulfur.

    摘要: This invention is a process for producing gaseous hydrogen sulfide in concentrated form from sulfur dioxide obtained from a dilute gas source by (1) reacting the SO.sub.2 with Na.sub.2 CO.sub.3 to form Na.sub.2 SO.sub.3, (2) reducing the Na.sub.2 SO.sub.3 to Na.sub.2 S, (3) reacting the Na.sub.2 S with NaHCO.sub.3 to form H.sub.2 S and Na.sub.2 CO.sub.3, (4) recycling part of the Na.sub.2 CO.sub.3 to the SO.sub.2 reaction step, (5) reacting the remainder of the Na.sub.2 CO.sub.3 with CO.sub.2 and H.sub.2 O to form NaHCO.sub.3 and (6) recycling the NaHCO.sub.3 to the H.sub.2 S formation reaction.
