    • A phosphorus vanadium oxide catalyst for the oxidation of a C.sub.4 hydrocarbon. The catalyst comprises a shaped body having a volume, or a fixed bed comprising shaped bodies having an average volume, of at least about 0.02 cc, and contains a promoter selected from among Bi, Sb, Ge, Ti, Zr, La, Ce, Ni, Zn, U, Sn, Si or mixtures thereof. The promoter is present in a proportion that enables the catalyst to have a developed surface area of at least about 28 m.sup.2 /g, and to exhibit a weight/area productivity of at least about 3.5 mg maleic anhydride/m.sup.2 -hr and/or a weight/weight productivity of at least about 100 g maleic anhydride/kg.cat.-hr. when contacted with a gas containing 2.4% by volume n-butane in air, at a gas flow volume to catalyst weight ratio of 2180 cc/g-min., under a pressure of 1.055.times.10.sup.2 -kPa-G, and at a temperature sufficient to maintain a hydrocarbon conversion of 85 mole percent. Methods for the preparation of the catalyst include activation by ANST.
    • 用于氧化C4烃的磷氧化钒催化剂。 催化剂包括具有体积的成形体或包含平均体积至少约0.02cc的成形体的固定床,并且含有选自Bi,Sb,Ge,Ti,Zr,La,Ce, Ni,Zn,U,Sn,Si或其混合物。 促进剂以使得催化剂具有至少约28m 2 / g的显影表面积的比例存在,并且显示出至少约3.5mg马来酸酐/ m 2 -hr的重量/面积生产率和/或 至少约100g马来酸酐/ kg.cat.-hr的重量/重量生产率。 当在空气中与含有2.4体积%正丁烷的气体在气体流量与催化剂重量比为2180cc / g-min的压力下在1.055×102-kPa-G的压力下接触,并且在足够的温度 以保持85%的烃转化率。 制备催化剂的方法包括ANST的活化。

    • A method for forming a joining profile in a structural member comprises providing an assembly having a base member, a forming body and a pair of side anvils having profiles formed therewithin. The method further comprises mounting the structural member on the base member, advancing the forming body toward the structural member such that the structural member is clamped to the base member, urging the side anvils toward flanges of the structural member, forming a profile in each of the flanges, and engaging protrusions of the side anvils with the web such that opposing portions of the web are forced upwardly by the protrusions at locations adjacent to each one of the flange profiles in order to accommodate formation of the flange profiles in the structural member. Formation of the joining profiles in the structural members allows for detachable engagement thereof with another member having a corresponding mating profile.
    • 一种在结构构件中形成接合轮廓的方法包括提供具有基部构件,成形体和具有在其中形成的轮廓的一对侧面砧座的组件。 该方法还包括将结构构件安装在基座构件上,使成形体朝向结构构件前进,使得结构构件被夹紧到基座构件上,将侧砧推向结构构件的凸缘, 所述凸缘和所述侧砧与所述腹板的接合突起使得所述腹板的相对部分被所述突起在与每个所述凸缘轮廓相邻的位置处被向上推动,以便适应所述结构构件中的凸缘轮廓的形成。 在结构构件中形成接合轮廓允许其与具有相应配合轮廓的另一构件的可拆卸接合。
