Patent ID: 7765852

Claim:
A method of conducting a non-destructive test on fused beads in a molded foam to measure a bead fusion quality of the fused beads, the method comprising: inserting a nozzle, directly and operatively connected to a member, into the molded foam to an insertion depth of the molded foam, the member having substantial planar surface, wherein the nozzle comprises: a tube having a wall; a plurality of apertures formed in the wall of the tube and distributed along the length of the tube, wherein an aperture in the plurality of apertures extends partially about a circumference of the tube; forming, by the member abutting the external surface of the molded foam when inserted, an air tight seal with the external surface of the molded foam, proximate to the point of insertion of the nozzle; supplying air from an air source that flows through an air flow meter, the member, and the nozzle into the molded foam; disbursing the air through the plurality of apertures, thereby causing the air to flow around the fused beads; and monitoring the air flow around the fused beads to obtain a monitored air flow.
