Abstract: The aim of the invention is to provide a method for conveying flowable substances, whose implementation does not require adherence to any special supply prerequisites. To this end, a gaseous conveying medium subjects the substances to the action of pressure which is alternately changed between two pressure levels such that at a low pressure level, the substances continue flowing, and by applying the higher pressure level, are conveyed in the desired direction of conveyance.

Abstract: The invention relates to a technology for pressurizing dust. The dust is fed from a storage hopper of a feeding device, the storage hopper being at ambient pressure. In the feeding device, the dust is pressurized by introducing high-pressure inert gas and fed to a high-pressure apparatus. By means of a hydraulically deflected membrane in the feeding device, the remaining volume to be relaxed after the dust sluicing and the consumption of inert gas are minimized.

Abstract: A method of, and apparatus for, transferring material, which may be hydrocarbon exploration and production industry by-products in the form of drill cuttings (48), from a first location to a second location is described. A first container (14) is provided containing fluid and the material is transferred from a first location outside of the container (14) to a second location inside the container (14). Fluid, which is typically air, is at least partially evacuating from within the container (14) in order to facilitate progression of the material into the container (14).
