Abstract: An applicator of a clip system includes an elongated member and a bushing coupled to a distal end of the elongated member and a coupling movably attached to the bushing. A capsule is coupled to the coupling via a coupling member hooked over a hook of the coupling. Proximal ends of clip arms are received within the capsule and a core member received between and connected to the proximal ends of the arms includes a projection and a failure point distal of the projection. The core member is coupled to a control member so that movement of the control member relative to the elongated member opens and closes the arms. The projection is configured so that, when the clip is clipped over tissue, the coupling is drawn into the body and the projection drives the coupling member radially outward off the hook to free the capsule.

Abstract: This invention reveals a pneumatic tire comprising a generally toroidal-shaped carcass with an outer circumferential tread, two spaced beads, at least one ply extending from bead to bead and sidewalls extending radially from and connecting said tread to said beads, and an innerliner which covers the inner surface and which is comprised of a halobutyl rubber, a filler and lignin. The incorporation of lignin into the innerliner prevents migration of moisture into the tire carcass which can lead to corrosion and consequential delamination of steel cords within the tire. Normally the lignin will be included in such innerliner formulations in an amount which is within the range of 1 phr to 20 phr. Lignin can also be used to protect the steel belts by incorporating it into other tire components located between the innerliner and the belts.
