  • Patent number: 10968303
    Abstract: In various embodiments, the present invention provides a strong, synthetic elastomer materials (and related methods for making same) with mechanical properties that are controlled by the stereochemically-defined double bonds within their backbone, yet have physical properties that are derived from monomer selection and defined, modifiable, chain end groups. The use of the organocatalyzed, stereospecific addition of thiols to activated alkynes, affords isolated high molar mass materials (>100 kDa) via step-growth polymerization with high levels of cis- or trans-double bond content. Furthermore, in various aspects of the present invention, it has been found that changing the monomer composition and chain end groups provides additional control over the materials' physical properties to provide more efficient compounding with polar additives. Using this approach to elastomer synthesis, further end group modification and toughening through various vulcanization strategies are also possible.

  • Publication number: 20060022388
    Abstract: A metallurgical vessel having a cylindrical upper end section (21) and a top section (22) fitted to the upper end of section (21) to form a top closure of the vessel about a central opening (24) through which to extend a gas injection lance for injecting gas into the vessel. Top section (22) is formed as a two-part domed construction comprising an outer annular panel (71) welded to the vessel top section (21) and an inner annular panel (72) removably fastened to outer panel (71), both panels being formed with inwardly concave curvature so as to form together the continuously domed top section (22). The two panels (71, 72) are fastened together by clamping bolts (79) extended through outturned flanges (76, 77) formed on annular flanges standing up from the panels (71, 72). On release of bolts (79) panel (72) is removable to provide access to the interior of the vessel.
