Abstract: In an injection molded polypropylene field joint of an oil or gas pipeline, the three- dimensional geometry of the injection molded/cast coating can have an influence on the stress placed on the line coating during cooling. Specifically, it has been found that molding or casting a coating having circumferential grooves, or other groove geometry, proximal to the interface with the line coating, will reduce line coating failure proximal to the field joint, in particular line coating failure related to the initial spooling/reeling of the pipe.

Abstract: A lid for a beverage container is provided. The lid comprises a top side (3), an underside (5) and a flange portion (7) for connecting the lid to the container. The lid further comprises at least one drinking aperture (17) which permits liquid to pass through the lid, and at least one baffle (19) which is attached to a perimeter of the at least one drinking aperture and extends downwards from the underside of the lid so as to prevent liquid flow through the aperture from one or more flow directions.

Abstract: A roof vent (or other opening closure means) for a grain bin is disclosed. Generally, a grain bin has a cylindrical bin body and a conical roof. The roof includes a plurality of wedge-shaped panels secured together in side-to-side relation and often one or more of these panels has an opening therein for accommodating a roof vent. A flange is provided on the roof panel defining an opening in the roof panel with the flange being sealably (preferably integrally) formed with the roof panel. The flange extends outwardly so as to prevent water flowing down the slope of the roof from entering into the opening.
