<p>A container vehicle for fluent contents, that is to say a container in which such contents can be securely held when In transit. It comprises a cylindrical vessel (1, 80) arranged with its axis (2) level and having axially-disposed ports (93, 96), valve means (94, 11; 98, 14) to prevent an above-axis height load within from spilling out of the ports, and sealed joint halves (92, 99) associated with the ports whereby to make sealed joints (91, 100) between those ports and input (10) and output (13) delivery pipes. The vessel can be rotated by external means (7, 8, 9) and contains at least one helical vane (18) within it which propels contents axially when the vessel is so rotated. The ports may coincide with bearings (3, 4) to support the weight of the vessel. The vehicle may be for the transport of powdered material, to be delivered into and discharged from the vessel when fluidised by pressurised air, in which case angled delivery and discharge spouts (11, 14) within the vessel may suffice as the valve means. Vehicles in containerised (60) form are described, also vehicles suitable for railway travel including variants in which the vessel (50) provides the structural link between bogies (36, 37) at opposite ends of the vehicle. Vessels including discharge means (74-77, 72) specially suited to liquid contents, and vessels (80) whose weight is supported by bearings, for instance air bearings (83) remote from the means (85, 86) which rotate the vessel, are also shown.</p> |
