Abstract: A viscous torsional vibration damper of the kind operating on the shear film principle has an annular shaped housing providing an annular working chamber within which is mounted an annular complementary inertia mass ring and a viscous damping fluid substantially fills shear film spaces between the working surfaces of the inertia ring and confronting working surfaces of the housing within the chamber. The cover has one or more lugs extending from the outside of an axially extending wall that engage with lugs inside the housing near the bottom wall. Rotation of the cover relative to the housing causes an axial force through the lugs that forces the cover into sealing engagement with the housing.

Abstract: A fishing rod holder having a base, a fishing rod holding tube pivotally mounted on the base, a one-way movable connection located between the base and the fishing rod holding tube for holding the fishing rod holding tube against movement to a more horizontal position while permitting the fishing rod holding tube to be swung to a more upright position by merely manually grasping the holding tube and pivoting it on its base, a disengagement member for disengaging the one-way movable connection to permit the fishing rod holding tube to be swung manually to a more horizontal position, with the one-way movable connection consisting of engaged serrated discs having relatively small serrations to permit the holding tube to be oriented at a plurality of relatively small angular positions between its horizontal and vertical limits of movement.
