A bodyside cover for an absorbent article is disclosed which includes two different materials to provide enhanced functionality. The bicomponent cover includes an apertured first material, which is positioned along the longitudinal central axis of the absorbent article, and a nonperforated second material secured to at least a portion of the first material. The first material has a rewet value which is less than, or equal to, the rewet value of the second material while the second material is softer than the first material. The first material is positioned below the principal point of fluid discharge and represents the primary fluid-receiving region of the cover. The second material is situated away from the principal point of fluid discharge and represents the secondary fluid-receiving region of the cover.

A containment and circulating system for drilling fluid is provided having generally circular tank means for receiving drilling fluid from a well during well drilling operations and from which the drilling fluid is withdrawn and injected into the well. The system incorporates a plurality of generally cylindrical tanks having cylindrical side wall means in normal relation with a substantially planar bottom wall. On opposed sides of each circular tank is provided angulated flow directing walls which intersect both the side wall and bottom wall. The flow directing walls receive the radiating flow from the impeller and direct it upwardly along opposed portions of the cylindrical side wall of the tank. An impeller is centrally located at the lower portion of each tank thereby inducing radiating flow of drilling fluid toward the lower outer wall structure of each tank. A pair of opposed flow lifting baffles are positioned in close proximity to the internal cylindrical surface defined by the tank wall and function to induce an upwardly directed component flow to the drilling fluid as it is circulated within the tank. The cooperating flow inducing activity of the flow directing walls and the flow lifting baffles develop controlled turbulence with minimal impeller force throughout the tank to retain substantially all of the solid particulate of the drilling fluid in suspension.
