Abstract: A vibration dampener for dampening vibration in a brake rotor comprising two elongated, flexible, stretchable, tubular members, one of which is shorter than the other. Weights are attached to the two members. Links connect the two members end-to-end in a closed loop capable of being stretched over the periphery of a relatively large diameter brake rotor. The links are releasable so that the shorter tubular member may be removed and the ends of the longer tubular member connected together in a closed loop capable of being stretched over the periphery of a smaller diameter brake rotor.

Abstract: An enclosure for a swimming pool or the like comprising a cover and a frame for supporting the cover. The frame has a plurality of longitudinally spaced laterally extending ribs which arch over the area to be enclosed and have their ends secured in the ground. The ribs are composed of a plurality of straight elements connected substantially end to end by angularly shaped tubular sections. The frame also has laterally spaced longitudinally extending members interconnecting the ribs. Gripper boards or strips are provided to anchor the cover at the perimeter of the enclosure.
