Abstract: The reformer (2) is designed for use with a large fuel cell power plant capable of producing megawatts of power, as, for example, would be used by a public utility. The catalyst tubes (16) in the reformer (2) have their upper ends at staggered elevations so as to be capable of having their temperatures individually monitored by infrared temperature sensors. The catalyst tubes (16) are mounted on a floating support within the reformer housing (4) so as to be free to undergo expansion and contraction during periods of internal temperature variation as the reformer (2) is operated. The floating support is preferably formed from fuel manifolds suspended in the reformer housing (4). Baffles (64) are included in the reformer housing (4) for evenly distributing heat to the catalyst tube (16) arrays. The reformer has a long burner (56) tube which is approximately the same length as the catalyst tubes (16).

Abstract: The new invention concerns the regulation of air volume in a conveying system comprising an air collecting line (37) in which the air volume and the corresponding air velocity, respectively, is regulated in the individual conveying pipelines (30-36) by a lifting body (4) resembling an airfoil. The latter works like a throttle flap and moves from an incidence angle ( alpha ,  beta ) of at least 10 degrees in the completely open position to 90 degrees in the closed position as a result of the lifting moments acting on it. The lifting body (4) itself regulates the air volume by means of blocking the air line cross section to a greater or lesser extent, wherein a balance is adjusted in every case between the air forces and lifting moments, respectively, which act at the lifting body (4) so as to be directed in a closing position and a counterweight (5) or countertorque, respectively, acting at the lifting body (4) in the opening direction. A responsiveness which has not been previously achieved can accordingly be achieved from every position and an optimal regulating characteristic, e.g. at an approximately constant air velocity, can accordingly be achieved independently of the air resistance occurring prior to the regulating unit.

Abstract: An infrared soldering iron for the fusing soldering (reflow soldering) of electronic components onto printed-circuit boards by means of a solder paste comprises a heating chamber which is ventilated with an essentially vertical air flow and in which the printed-circuit boards rest on a support (37) which is at least partially permeable for infrared radiation and for the air flow. Above and below the support there are arranged infrared radiators (39-42) which heat the printed-circuit boards (which are furnished with the components and are provided with the solder paste) to different temperatures during a heating phase and a fusing phase. For the uniform heating of the printed-circuit boards, the support (34, 35, 37), which is permeable for the infrared radiation, has a flat air block (46) as a mount for the printed-circuit boards (e.g. 38), which air block is impermeable for the air flow but is permeable for the infrared radiation. The air block (46) projects at the sides completely beyond the printed-circuit boards placed thereon, but is arranged at a distance (48, 49) from walls (7, 8) bounding the heating chamber. In consequence, it bounds at least one gap (gap widths 48, 49) for the vertical air flow. For soldering operations in a protective gas atmosphere, a smaller chamber (53) is arranged in the heating chamber. <IMAGE>

Abstract: One end of a crimp terminal is formed with a wire insulation grip portion and a bare conductor grip portion. The bare conductor grip portion is divided in two. When the terminal is crimped on the wire, the divided bare conductor grip portions are crimped in such a way that the cross section of the conductor portion held by one of the divided bare conductor grip portions will be deformed more than 40% and the cross section of the adjacent conductor portion held by the other grip portion will be deformed 10 to 30%. The first crimped portion, which is deformed more than 40%, provides a reduced electrical contact resistance and the second crimped portion, which is deformed 10 to 30%, provides a good mechanical strength or connecting force between the terminal and the wire. Thus, the crimped terminal as a whole exhibits a good electrical characteristic while at the same time providing a good mechanical strength.
