    摘要： A gondola tub type railway car having an arrangement for transferring payloads from the car side panels more directly to the bolsters. The car at each end has a lower bolster for support by a car truck, and an upper bolster secured to the lower bolster preferably through a shear plate. A center plate unit extends upwardly from the lower bolster into the upper bolster and is secured to the latter. The car, at each end, is provided with a reaction beam located inboard of the associated bolster, and is secured to the shear plate and to side members, and cooperates with the bolster in resisting the couple created by draft and buff forces acting in offset relation to the plane of the shear plate.

    摘要： A catalytic process for the hydroformylation of olefinic, sulfur containing thermally cracked petroleum streams to produce aldehydes and/or alcohols is disclosed. The catalysts are homogeneous transition metal carbonyl complexes. Especially preferred catalysts for low and medium pressure hydroformylation are cobalt and rhodium carbonyl hydride complexes in which some of the carbonyl ligands have been replaced by trivalent phosphorus ligands. In a preferred high pressure hydroformylation, the sulfur-containing naphtha and gas oil distillate feeds are proudced from vacuum residue by high temperature thermal cracking. Such feeds contain more than 20% olefins with 1-n-olefins as the single major types. These olefin components are hydroformylated in the presence of a cobalt cabonyl complex to produce a novel type of semilinear aldehyde and/or alcohol product containing an average of less than one alkyl branch per molecule. The alcohols are converted to dialkyl phthalates and other esters having a unique balance of plasticizer properties. They are also useful for producing novel surfactants, particularly ethoxylated derivatives.For the preparation of products containing minimal concentrations of sulfur compounds, narrow distillate fractions of thermally cracked residua are preferred. In the C.sub.6 to C.sub.11 carbon range, single carbon fractions of sharply reduced aromatic hydrocarbon and thiophenic sulfur content can be obtained. These fractions of increased linear olefin content can be advantageously used as hydroformylation feeds in the derivation of low sulfur containing alcohols and related products of increased linearity.
