Abstract
The invention features a modified catch tube component capable of performing the function of the conventional catch tube and the conventional MEM simultaneously. The catch tube will also feature a capability to accept modular units of mass for adjusting the available angular momentum (of the spinning catch tube) as well as to incrementally adjust inertial resistance for controlling post-impact translational motion. The safety and performance enhancements of the modified spinner are achieved by the above mentioned integration of the MEM with the catch tube. This invention will eliminate MEM free flight and prevent excessively soft, or excessively hard projectile impacts. Equipment such as rails and wheel sets are used to assure that the motion of the catch tube is constrained to translation and to rotation. The invention contrasts conventional spinners in that the motion of a conventional catch tube is limited to rotation only and the MEM to translation and rotation.
