An elongate container (7) for the transport of bulk powders is provided along its base with a longitudinally sloping membrane support. A gas permeable membrane (11) is mounted on the support and the support is itself unsupported relative to the container between its longitudinal and transverse ends.
An elongate container (7) for the transport of bulk powders is provided along its base with a longitudinally sloping membrane support. A gas permeable membrane (11) is mounted on the support and the support is itself unsupported relative to the container between its longitudinal and transverse ends. A method of conveying bulk powder using such a container is also described.

The invention claimed is: 1. An elongate container for the transport of bulk powders, the bottom of the container being provided with a longitudinally sloping membrane support extending along at least a portion of the length of the container, a gas-permeable membrane mounted on said support, said support being unsupported relative to the container between longitudinal and transverse ends of the support wherein the membrane is curved in a direction transverse to the length of the container, the extent of curvature changing along the length of the membrane. 2. A container according to claim 1, wherein the curvature of the membrane increases in a direction from a lowest point to a highest point of the membrane. 3. A container according to claim 1, wherein a plurality of membranes are arranged along the base of the container in lengthwise juxtaposition. 4. A container according to claim 3, wherein adjacent membranes slope in opposite directions along the length of the container. 5. A container according to claim 1, wherein a container, at least when arranged for unloading of bulk powder therefrom, is provided with a discharge pipe, one end of which is located adjacent the lowest point of the or each membrane. 6. A container according to claim 5, wherein the discharge pipe is connected to means, located outside the container, for pneumatically conveying powder from the container to a position exterior thereof. 7. A container according to claim 1, wherein the or each membrane is inclined at an angle of from 10° to 15° relative to the bottom of the container. 8. A container according to claim 1, wherein means are provided, at least when the container is to be unloaded, to cause powder located above the membrane to be fluidised. 9. A container according to claim 8, wherein the fluidising means includes means for delivering gas under pressure to the space below the sloping membrane. 10. A container according to claim 1, wherein the membrane is made of woven fabric, porous metal sheet or porous plastic sheet. 11. A container according to claim 1, wherein the container is cylindrical. 12. A container according to claim 11, wherein the container is a pressure vessel located within a standard ISO Tank Container dimensioned frame. 13. A method of conveying bulk powder to a destination therefor including the steps of: loading the bulk powder into a container in which the bottom of the container is provided with a longitudinally sloping membrane support extending along at least a portion of the length of the container and a gas-permeable membrane mounted on said support and curved in a direction transverse to the length of the container, the extent of curvature changing along the length of the membrane; transporting the container to a location in the vicinity of said destination; feeding gas under pressure to a position between the membrane and the bottom of the container so as to fluidise the bulk powder within the container; and pneumatically conveying said fluidised bulk powder from the container to said destination. 14. A method according to claim 13, wherein, during the loading of the bulk powder into the container, air is extracted therefrom. 15. A method according to claim 14, wherein air is extracted from below the membrane, thereby drawing entrapped air from the powder and through the membrane to increase the bulk density of the powder. 16. A method according to claim 13 including providing said support being unsupported relative to the container between longitudinal and transverse ends of the support. 17. An elongate container for the transport of bulk powders, the bottom of the container being provided with a longitudinally sloping membrane support extending along at least a portion of the length of the container, a gas-permeable membrane mounted on said support, and wherein the membrane is curved in a direction transverse to the length of the container, the extent of curvature changing along the length of the membrane. 18. A container according to claim 17 wherein the membrane support is in the form of a foraminous curved plate.
