Abstract: A container module for intermodal transportation and temporary storage of dry flowable product includes a pressure tank supported by hanger plates welded to end frames of a support frame defining a standardized container envelope. The pressure tank has a wall with a flat top center section and short flat side sections joined by upper cylindrical intermediate sections and lower cylindrical sections below the flat side sections which blend into a plurality of intersecting, downwardly discharging hoppers. Elongated beam members extending along each side of the support frame tie the hoppers together to resist bending of the suspended tank.

Abstract: A universal joint yoke having a tubular body and a pair of ears projecting generally axially therefrom is provided. The ears-have an inner surface, an outer surface and an ear connecting surface. The ear connecting surface has a pair of lower portions, a pair of transition portions and an upper portion. The lower portions are oriented such that a generally straight line drawn in the tubular body connecting surface plane goes through (i) a point at the junction of the ear outer surface and the ear connecting surface; (ii) a point at the junction of the ear inner surface and the ear connecting surface; and (iii) a point on the axis of the tubular body. The upper portion is oriented such that a generally straight line drawn between (i) a point on the junction of the ear outer surface and the ear connecting surface and (ii) a point at the junction of the ear inner surface and the ear connecting surface is generally parallel to the common axis. The universal joint yoke includes a generally concave endcap.
