Abstract: A vibration absorber for attachment to a single conductor suspended transmission line to suppress vertical aeolian vibrations. A clamp arm has one end attached to a suspended cable and another end rotatably coupled to a housing having a weight extending therefrom through two frictionally-engaged elements which provide coulomb friction when the clamp arm is caused to rotate relative to the housing as a result of said vibrations. A separate resilient member couples the clamp arm to the housing to restore the initial orientation of the clamp arm.

Abstract: A hand cart comprises a truck and an upwardly open container mounted on the truck. The truck has an elongate frame provided at one end thereof with a handle and at the opposite end thereof with a nose, against which the container abuts with projections on the front of the container engaging in openings at the base of the nose, and a manually actuable clip or the like is provided for releasably securing the rear of the container to the frame. With the container attached to the frame, the cart can be used as a wheelbarrow and, with the container removed, the truck can be used by itself. A detachable nose extension and a detachable bag support are disclosed and the truck can be disassembled for flat packaging.
