Abstract
Abstract Means and method for harnessing inertial forces so as to suppress rebound-resonance resulting from abruptly stopping a moving body. The inertial forces are generated by a movable mass yieldably and resistently coupled to the moving body. The movable mass maintains its motion when the body is abruptly stopped and the inertial forces coupled to the moving body are out of phase with the rebound reaction forces generated when the movement of the body itself is halted.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
138 words
In a system having a first moving mass and stopping means for abruptly stopping the movement of said first moving mass, means for reducing the tendency of said first moving mass to rebound from said stopping means comprising; a second mass movably coupled to said first moving mass such that said second mass will move with said first moving mass and will maintain its motion due to its inertia when said first moving mass is abruptly stopped by application of said stopping means; means for coupling the inertial force of the maintained movement of said second mass to said first moving mass so as to continue to impell said first moving mass against said stopping means, said inertial force acting counter to the rebound reaction force resulting from application of said stopping means to said first moving mass.
Claim 2
Dependent Claim
138 words
In a system having a first moving mass and stopping means for abruptly stopping the movement of said first moving mass, means for reducing the tendency of said first moving mass to rebound from said stopping means comprising; a second mass movably coupled to said first moving mass such that said second mass will move with said first moving mass and will maintain its motion due to its inertia when said first moving mass is abruptly stopped by application of said stopping means; means for coupling the inertial force of the maintained movement of said second mass to said first moving mass so as to continue to impell said first moving mass against said stopping means, said inertial force acting counter to the rebound reaction force resulting from application of said stopping means to said first moving mass.
