  • Patent number: 9228606
    Abstract: A hook, a hold down strap and a method for holding down an underground tank. The hook includes a base portion connectable to the hold down strap; a curved portion extending from the base portion and defining a concave receiving area having an entrance sized and configured for receiving an anchor element. The hook includes at least one hooking aid member being a flexible member or an extension member. The flexible member extends across the entrance of the concave receiving area and is sized and configured to bend from a closed position to an open position such that, when the anchor element traverses the entrance, the flexible member bends from the closed position toward the concave receiving area to the open position, thus allowing the anchor element to enter the concave receiving area. The extension member extends from the curved portion beyond the entrance of the concave receiving area.

    Abstract: Methods for the synthesis and use of several variations of styrene maleic acid-based polymers and the hydrogel tissue bridges that can be formed from such polymers. Specifically, a method is disclosed for synthesizing a styrene maleic acid-based polymer that can be dissolved in DMSO and injected into the vasa deferentia of male subjects, creating a hydrogel tissue bridge. This hydrogel tissue bridge can occlude the vas deferens, thus forming an effective male contraceptive. Additionally, this male contraceptive can be reversed by injecting the lumen of the vas deferens with a basic buffer solution to dissolve and remove the hydrogel tissue bridge.

    Abstract: The exemplary embodiments disclosed herein relate to activating methods for initiation polymerization of methylene malonates and other polymerizable compositions. The polymerization may be activated by anionic or free radical mechanisms. Because the polymerization may occur very quickly upon contact between the activating agent and the polymerizable composition, methods are provide herein for separating or otherwise rendering the activating agent ineffective to initiate polymerization, until such a reaction is desired. The separation may be physical (separate packaging, separate application steps, encapsulation) or it may be based on latent-activation methods (activation precursors, UV activation). Products formed from the methods disclosed herein may include inks, adhesives, coatings, sealants, reactive moldings, fibers, films, sheets, medical polymers, composites, laminates and the like.

  • Patent number: 7893176
    Abstract: The disclosure provides for a process and polymerization system to produce isoolefin polymers (72) utilizing polymorphogenates (16, 26) in the catalyst system to control polydispersity (MWD). The disclosure also provides a catalyst system (20) comprising a plurality of active catalyst complex species (34) formed by combination of a Lewis acid (24), an initiator (22) and a polymorphogenate (26), as well as polymers made using the catalyst system or process. The polymorphogenate (16, 26) can promote or mimic the formation of different active catalyst complex species (34) having different polymerization rates, i.e. different rates of propagation, chain transfer, or termination, as observed by different polydispersities resulting from the presence of relatively different proportions of the polymorphogenate.
