Abstract: A drill pipe (10) having an elongate tubular body (12) with an interior surface enclosing a main bore (14) which extends generally parallel to a longitudinal axis (A) of the tubular body (12) from a first end to a second end of the tubular body (12), a side port (16) provided in an exterior surface of the tubular body (12), a side bore (18) extending through the body (12) from the main bore (14) to the side port (16), and a valve assembly (20, 22) which is operable to substantially prevent flow of fluid along the main bore (14) and to substantially prevent flow of fluid along the side bore (18), wherein the valve assembly (20, 22), side port (16) and side bore (18) are provided in a first connection portion (10a) of the drill pipe (10) at the first end thereof, the first connection portion (10a) comprising a thickened portion of the tubular body (12) in which the separation of the interior surface and the exterior surface is substantially greater than the adjacent portion of the tubular body (12), the length

Abstract: An inductive cap sealer (10) for sealing an inner seal over an opening (54) in container (52) includes a vented sealing head (12). The sealing head (12) contains an induction coil (24) for producing an electromagnetic field when energized by a power supply. Field focusing elements (26) contain the coil (24) and direct the electromagnetic field to a sealing region beneath the sealing head (12). The housing (20) has a central inlet vent (40) flanked by two outlet vents (42, 44) aligned with a vent plate (46) inside the housing (20) having a plurality of small openings (48) which allow a fan (18) to blow cooling air through the sealing head from only one side of the sealing head (12) in a generally U-shaped flow pattern, preferably from the side opposite the sealing region.
