Abstract
Abstract In an apparatus for producing vibrations, there is provided a combination consisting of a housing having an annular channel and at least one mass accomodated in and movable circumferentially of the channel. The combination further includes an arrangement for effecting movement of the mass circumferentially of the channel to respective locations therein. Abutments are provided in the channel for impeding movement of the mass through distances in excess of a predetermined portion of arc.
