Title: Abrasive swivel assembly and method

Abstract

This patent describes an assembly for providing a rotating, particle-laden fluid jet. It comprises tube means including a straight inner tube for containing within its interior a stream of particle-free fluid which flows from an upstream pressured source of the fluid through the inner tube and out the downstream end of the tube, the tube means also including a straight tubular section surrounding the inner tube; means for rotating the straight tubular section of the tube means about the longitudinal axis of the straight tubular section; means for introducing solid particles into the at a point along the rotating straight tubular section so as to cause the particles to mix with the fluid stream at the downstream end of the tube, whereby to produce particle-laden fluid stream; and means for forming a rotating jet from the particle-laden stream; and the straight tubular section of the tube means including a pair of spaced apart longitudinal subsections having confronting flanges and bolts coupling the flange means and therefore the subsections for rotation by the rotating means.
