    • A combined door carrier and hanging device for transporting and hanging a door panel is provided. The combined device is generally defined by an elongated carrier structure having a first end and a second end, and includes a wheel supporting chassis to which a pair of beams are mounted and spaced apart to define an elongated slot. The chassis further supports a plurality of floor engaging foot members at the second end, a vise mechanism at the second end, and an axle having a plurality of floor engaging wheels at the first end. More specifically, the elongated slot is adapted to closely receive a door panel across its thickness, wherein one of the pair of beams is rigidly attached the chassis at the first end, but is free to flex at the second end to facilitate clamping of a door panel in the slot. The vise mechanism is attached to the chassis at the second end, which vise when operated compresses the second end of one beam moving the beam toward the other beam, thereby narrowing the slot and hence clamping upon a panel placed therein.
    • 提供了一种用于运输和悬挂门板的组合门架和悬挂装置。 组合装置通常由具有第一端和第二端的细长载体结构限定,并且包括轮支撑底盘,一对梁被安装到所述车轮支撑底盘并间隔开以限定细长的槽。 底架还支撑在第二端处的多个地板接合脚构件,在第二端处的虎钳机构和在第一端具有多个地板接合轮的车轴。 更具体地,细长槽适于在其厚度上紧密地容纳门板,其中一对梁中的一个在第一端处刚性地附接底架,但是在第二端处可自由地弯曲以便于夹紧门 面板在插槽中。 虎钳机构在第二端附接到底架,当操作时,当操作的虎钳将一束光束的第二端移动到另一束光束时,从而使狭槽变窄并因此夹在放置在其中的面板上。

    • Sulfur trioxide is formed by a process wherein a first gaseous stream comprised of SO2, SO3, and oxygen and/or air is passed into a bed of a vanadium-containing catalyst that oxidizes S02 to SO3and that releases therefrom a second gaseous stream comprised of sulfur trioxide. This process is improved in a first case by providing vaporized sulfur in the first gaseous stream so that the resultant mixture passes through a substantial portion of the catalyst bed, and maintaining the catalyst bed at one or more temperatures in the range of about 450 to about 700° C. The sulfur is oxidized to S02. As a result, the second gaseous stream released from the downstream end portion of the catalyst bed has an enriched content of sulfur trioxide, which can be used for production of compounds such as tetrabromophthalic anhydride. In a second case, a stream of sulfur dioxide is generated from sulfur and an oxidant, and this stream is introduced into the first gaseous stream referred to above. In this second case, the feed of sulfur dioxide replaces the vaporized sulfur used in the first case. As in the first case, an enriched stream of sulfur trioxide is released from the downstream end of the catalyst and can be used for producing compounds such as tetrabromophthalic anhydride.
    • 通过以下方法形成三氧化硫:将由SO 2 SO 3 SO 3,SO 3 3组成的第一气态物流和氧气和/或空气通入含钒的床 将SO 2 SO 2氧化成SO 3的催化剂,并从其中释放出由三氧化硫组成的第二气态物流。 在第一种情况下,通过在第一气流中提供蒸发的硫使得所得混合物通过催化剂床的大部分,并将催化剂床保持在约450至约 700℃。硫被氧化成S0 2。 结果,从催化剂床的下游端部排出的第二气态物质具有富含三氧化硫的含量,可用于生产四溴邻苯二甲酸酐等化合物。 在第二种情况下,硫和氧化剂产生二氧化硫流,并将该流引入上述第一气流。 在第二种情况下,二氧化硫的进料代替第一种情况下使用的汽化硫。 如在第一种情况下,富集的三氧化硫流从催化剂的下游端释放出来,可用于生产化合物如四溴邻苯二甲酸酐。

    • An aircraft wing slat for mounting to a leading portion of an aircraft wing includes a main body section and a forward section, wherein the forward section is demountable from or releasably secured to the main body section. The forward section may have a nose skin with an electrically powered heater. The electrically powered heater may be integral with the nose skin and may be microporous such that it is integrated into surrounding dielectric to contribute to the mechanical strength of the nose skin. A demountable forward section of an aircraft wing slat, a main body section of an aircraft wing slat arranged to receive a demountable forward section, an aircraft wing and an aircraft wing slat with a nose skin with an electrically powered heater are also disclosed.
