  • Patent number: 9932499
    Abstract: The present invention relates to a polymerizable composition, comprising a polymerizable monomer of formula (I), a copolymerizable UV-initiator, at least one copolymerizable (meth)acrylic monomer: R1—(OCH2CH2)n-L-OC(O)—CR2?CH2??Formula (I) wherein R1 is hydrogen or a C1-C6 alkyl group, n is an integer from 1 to 100, L is a single bond or a divalent linking group, preferably a single bond or a C1-6 alkylene group, and R2 is hydrogen or a CH3 group; and optionally (d) at least one copolymerizable non-acrylate monomer; wherein the amount of the polymerizable monomer of formula (I) is between 2.5 and 40% by weight of the total of all polymerizable monomers (a), (b), (c) and (d). The invention also relates to a random copolymer obtained by reacting the polymerizable composition, a crosslinked product of the random copolymer and an adhesive composite material comprising the random copolymer or the crosslinked product on a substrate.

  • Patent number: 5406697
    Abstract: An apparatus for assembling mechanical components, and particularly in a mass-production line, includes a fixture to clamp and support the component and a flexible connector for supporting the combined weight of the fixture and the component. The fixture is particularly configured to position the center of gravity of the fixture and the component in substantial vertical alignment with the flexible connector so that the component is oriented for direct assembly to the structure. The apparatus is particularly useful for assembling the components of an automobile, such as the doors, to its body with little or no manual manipulation on the part of a worker.
