Abstract: The present disclosure is to a fly fishing line and a method of making a fly fishing line. The method includes preparing a composition comprising a polymer resin, a co-polymer of silicone, and one or more other polymeric materials. The method includes applying the composition around an elongated core. The method also includes exposing the composition to conditions that form a coating around the elongated core thereby forming the fly-fishing line. The composition is a plastisol composition and the polymer resin is a polyvinyl chloride resin. The fly fishing lines include an elongated core a coating disposed around the elongated core. The coating comprises a polymer resin, a co-polymer of silicone, and one or more other polymeric materials.

Abstract: A breaker fluid may include a base fluid; and an inactive chelating agent. A process may include pumping a first wellbore fluid comprising an inactive chelating agent into a wellbore through a subterranean formation; and activating the inactive chelating agent to release an active chelating agent into the wellbore.

Abstract: A free-standing collapsible panoramic theatre is described. When assembled, the theatre includes a multiplicity of vertical screens arranged in a polygonal arrangement that defines an internal viewing region. The viewing screens are supported by a multiplicity of towers which are located external to the polygonal arrangement with one tower located at each vertical corner of the polygonal arrangement. Each tower has a base, a support structure extending vertically from the base, a manually-operable alignment mechanism which permits the vertical orientation of the support structure to be adjusted, a pair of upper and lower screen support brackets mounted for telescopic movement on the support structure and releasably retaining the pair of adjacent viewing screens at the vertical corner associated with the tower, and a projector support housing for supporting a projector.
