Abstract: An improved electrically-heated contact vaporizer (EHCV) for a catalytic hydrocarbon reformer. The EHCV has an electrically-heated vaporization surface and a helical-wound flow director. Preferably the EHCV includes a port and internal passages to permit controlled entry of an oxygen-containing gas, preferably air, into a flowing stream of vaporized fuel near the exit of the EHCV to mix with the vaporized fuel and spontaneously combust, forming hot gases for heating the reforming catalyst. A third wall may be provided to surround the outer wall of the air passage to provide further thermal insulation against heat loss.

Abstract: A diverter valve is disclosed and may comprise an actively cooled valve actuation section, an actuator, and a valve section comprising a rotationally actuated valve plate that is structured to be rotationally actuated by the actuator to direct flow wherein the actuation section may be thermally insulated from the valve actuation section.

Abstract: A method and apparatus for spin forming a portion of a workpiece includes at least two rollers rotatable about a spin axis. Each one of the rollers is axially and radially offset from the others. An axial drive mechanism reciprocates the rollers or workpiece to causes the first roller and then the second roller to sequentially engage the workpiece. A higher reduction ratio is achieved which enables improved efficiency. The present invention reduces floor space requirements as the forming operation may be completed on a single machine.

Abstract: A method and apparatus for spin forming a portion of a workpiece where the formed portion has a formed axis that is non-coaxial with the non-processed axis of the workpiece includes at least two rollers rotatable about a spin axis. Each one of the rollers is axially and radially offset from the others. An axial drive mechanism reciprocates the rollers or workpiece to causes the first roller and then the second roller to sequentially engage the workpiece. A pivoting mechanism rotates the rollers or workpiece about a pivot point from a first angular position to a second angular position during a forming operation to create a formed portion that is oblique to the non-processed portion or is substantially curved. A higher reduction ratio is achieved which enables improved efficiency. The present invention reduces floor space requirements as the forming operation may be completed on a single machine.
