  • Publication number: 20160369521
    Abstract: A securing device anchors a flag pole inside a boats rod holder so the boat can operate while flying a flag. The securing device includes an elongated cable, preferably including a protective sheathing, with a securing device such as an eyelet connector at one end for connecting to a flag pole, and a hooking device such as a snap hook at the other end. The device detachably connects a flag pole to the cross bar of a boat's rod holder.

  • Patent number: 4447475
    Abstract: A process of incorporating non-polymeric particulate matter such as magnetic materials, pigments and minerals, into a cross-linked styrene-based polymeric matrix, which process comprises dispersing the non-polymeric particles with a polymeric dispersant in a medium containing one or more vinyl monomers and a crosslinking agent, and adding a polymerization initiator. Typical polymeric dispersants are copolymers, styrenes and tertiary-nitrogen-containing vinyl monomers. Non-polymeric particulate matter incorporated into polymeric beads by this process is resistant to chemical attack and the beads may be used to prepare composite adsorbents or ion exchange resins.

  • Patent number: 4246355
    Abstract: Processes for making copolymers comprising treating a reaction mixture of a monomer and a substrate comprising ferromagnetic material located in a polymeric matrix so as to polymerize the monomer in a manner that it forms a polymeric shell grafted on to and surrounding the substrate, the polymerization of the monomer being initiated by adding the components of a redox system sequentially to the reaction mixture.
