  • Patent number: 9975142
    Abstract: A fluid applicator tool that includes an applicator portion including a pair of arcuate clamping members that each include an inner radial portion and an outer radial portion, an absorbent media extending along the inner radial portion of each arcuate clamping member, and a hinge coupled between the pair of arcuate clamping members. The hinge is operable for rotating the pair of arcuate clamping members relative to each other for positioning between an open position and a closed position. The pair of arcuate clamping members are oriented such that a through hole is defined therebetween when in the closed position.

  • Patent number: 7287406
    Abstract: An apparatus and method including a die assembly and tooling, which includes a draw bolt and coaxially disposed expandable element. When control of the apparatus is initiated the die assembly and draw bolt retract or move down over the work piece until the die assembly is seated in the die holder. The draw bolt continues to move down which causes the elastomer insert to expand and push the work piece outwardly forcing the work piece to conform to the contour of the die assembly creating the desired transition diameter.
