Anti-bounce device for preventing the multiple shocks of a moving mass after a first impact against another element

摘要

An anti-bounce device for avoiding the multiple shocks of a moving mass after a first impact against another element. Magnetic arrangements are associated with element for exerting an attractive force on the mass sufficient to prevent possible bouncing. These arrangements comprise, for example electromagnets and circuits for connecting the electromagnets to a current source via a switch. Permanent magnets may also be associated therewith. The direction of the electric current is then chosen so that the electromagnetic forces developed are added to the attractive forces of the permanent magnets or else for cancelling these latter out, which allows the mass to be released.
