Abstract: In a heated transport tank, the lower zone of the tank jacket 10 is surrounded by an outer shell 15 spaced from the jacket by socket-type projections 16 integrally formed in the shell 15. The outer shell 15, which forms a vapour flow chamber 20, extends throughout the axial length of the tank. At an intermediate location, where the tank is supported by a transverse bar 11 of a base structure via a transverse saddle 25, the socket-type projections 16 are reinforced by spacers inserted between the tank jacket 10 and the shell 15, each spacer being formed as a stack of comparatively thin annular discs. The individual discs are capable of conforming themselves to the local curvature of the tank jacket 10 and following instantaneous variations in curvature, thereby ensuring a uniform distribution of forces under all load conditions.

Abstract: A freight container for flowable materials includes a tank (10) and diagonal members (15) which serve to accommodate longitudinal forces occurring in operation. The diagonal members (15) extend from the end groups of the container and are joined by transition pieces (20) to reinforcing rings (11) of the tank (10). Each transition piece (20) is composed of at least two brackets (20, 21) joined to the corresponding diagonal member (15) and to the reinforcing ring (11). Longitudinal bars may be fitted between the lower diagonal members of the container.

Abstract: In a freight container the tank is joined via saddle means to end frames which are provided with the standardized corner fittings which are normally used in container design and determine the outer dimensions of the container. Each saddle means in its simplest form consists of a cylindrical end ring welded to the relatively less curved spherical main portion of the tank end portion surrounded by the highly curved knuckle zone, and of a saddle ring of L-shaped cross-section having its radially extending flange secured to the end frame and/or diagonal struts thereof and its second flange extending in tank axial direction welded to the end ring. This structure permits a strong connection between the tank and the end frame, while the loads transmitted by the tank are almost completely directly introduced into the corner areas of the end frame. At the same time it permits the "breathing motions" occurring on account of temperature and pressure variations in the knuckle zone of the tank end portion.

Abstract: A corner fitting is disclosed for freight containers, particularly for small and medium size containers. The corner fitting includes three mutually perpendicular side walls connected to one another to form a section of a corner of a cube having its apex pointing outwardly from a freight container when in an in-use position. Container handling openings are provided in at least one of the sidewalls and in an oblique triangular surface extending transverse to a diagonal through the corner apex. Particularly preferred embodiments of the corner fitting are formed from sheet metal blanks which are cut and bent along fold lines to form the sidewalls.

Abstract: The corner portions of a small or medium freight container are formed by the respective three frame elements (31,32,33) of the container frame and by a corner fitting (30) welded thereto. The frame elements are hollow elements of essentially square cross-section. The corner fitting (30) is formed with a corner opening (24) which is dimensioned so that the clear cross-sections of the frame elements (31, 32, 33) are accessible as fork truck channels intended for the arms of a fork truck through the respective corner fitting. The edges of the corner fitting (30) and the frame elements (31, 32, 33) inserted into the edge regions of the corner fitting are formed with aligned corner holes (25, 26) used for insertion of a crane hook tip or for securing and latching of coupling or lashing elements.

Abstract: A pressure-resistant container for liquids, gases, or loose material is composed of at least two part-cylindrical shells which have mutually parallel axes and intersect each other so as to form troughs between the tops and bottom thereof, respectively. In accordance with a preferred embodiment, the ends of the part-cylindrical shells are joined at their edges along the height of the longitudinal troughs formed between the tops and bottoms of the part-cylindrical shells of the container by their intersection, whereby a central shell element forms tunnels respectively interconnecting the tops and bottoms of the part-cylindrical shells.

Abstract: A transport container of the type made from cylindrical shells for use in the combined handling of liquids gases or loose material. The transport container is designed for emptying under pressure or by gravity, with connections for fixtures wherein stresses in the region of the connections are reduced.

Abstract: A freight container for flowable substances comprising a fully closed vessel formed at least partly of cylindrical sheet metal, two rectangular end frames interconnected by corner fittings for lifting and stacking the freight container and saddle members connected to the vessel and respective frame members. According to preferred embodiments, the saddle members are formed of sheet sections of an arched area and planar triangular surfaces adjacent opposite lateral edges of the arched area, each of the saddle members being interposed between an adjacent corner of the end frames and the vessel. The arched area has a conical surface having an apex located near an associated corner of the end frames and an arcuate base edge curved to conform with the wall of the vessel. Each of the triangular surfaces has an axial outer edge beginning near the apex of the conical surface and extending outwardly therefrom and being connected to an adjacent one of the members of the end frames.

Abstract: The improved double-walled transport container for transporting liquids and gases which have to be protected against heating or cooling and against mechanical shock, has a fully insulated inner vessel and an outer vessel comprising an upper shell, a lower shell and two dished endwalls. A shock-absorbing and thermally insulating layer is provided between the outer and the inner vessel, and support flanges extend over the entire length of the outer vessel. The sum of the distances between the endwalls of the inner and the outer vessel is at least equal to the distance of the crest of the arch from the edge of an endwall of the outer vessel.

Abstract: For charging and discharging a freight container, a device for tipping the container has a U-shaped frame, to which two tipping cheeks are connected which are adapted to be raised and lowered together and to pivot and which have rotary locking devices for engaging the lower corner fittings of the freight container. The device can be mobile and self-propelled or towable, is collapsable into a relatively small space when not in use and has hydraulic thrust and tipping actuators.
