Abstract: Rotational motion generates velocity of a mass wherein the mass' release from the rotating system, becoming a projectile, and subsequent impact can result in cutting, abrasion, mixing of chemicals, coating, and other surface and bulk volume effects including the transfer of momentum. Structures and devices are used to insert a mass into a rotating device. While inside the rotating device the mass gains velocity. Transitioning from the rotational system to a stationary surface is accomplished with a minimum of velocity loss by selecting trajectories, air flows, and surface finishes to reduce energy losses in the mass' transition onto the stationary surface and info a fixed stationary guide tube, and ultimately to an impact point. Single and multiple conduits, stationary and rotating, can be used to accomplish complex chemistry and physics affects.
