Abstract
Abstract An energy-dissipating receptacle for use with a fluid jet cutting system is disclosed wherein the interior cavity of the receptacle has generally converging sidewalls in the direction of jet flow. A plurality of circulating suspensoids within the cavity are impinged upon by the jet to dissipate the jet's kinetic energy. Means are included for permitting the egress of spent jet fluid while retaining the suspensoids.
