In a centrifugal screening apparatus wherein a housing (10, 11) mounts a screen assembly (12) and a scroll assembly (20) to be differentially rotated about the machine axis, there is provided an inlet assembly (30) having an inlet body (31) defining an annular inlet space (32) coaxial with and opening in to an open apical end of the screen assembly (12) and a material supply conduit (35) delivering material to be screened to the annular space (32) and being aligned in a tangent to the annular space to deliver material to the screen assembly (12) substantially in the direction of rotation of the screen assembly (12).

A flow-through sampling apparatus for sampling a bulk solid mixture includes a main body forming an opening. A screen is located in the opening and forms a plurality of sample zones within the main body. The apparatus further includes a first slide door that is movable above the screen so as to close one side of the opening. Further, the apparatus includes a second slide door that is movable below the screen so as to close the other side of the opening.

A material sampling system for obtaining a plurality of substantially similar samples of granular material, such as grain or other crop material, from a load of granular material is provided. The system can include a sample extractor for obtaining a sample portion of granular material, a sample divider operative to divide the sample portion of granular material into a plurality of smaller samples of granular material in a plurality of sample containers and a sample transfer conduit for transferring the sample of granular material from the sample extractor to the sample divider. The sample portions can be taken at regular sample time intervals throughout the entire load of granular material to get an accurate representation of the granular material and information about the samples in the sample containers can be obtained by the system while it is obtaining the samples and this information stored for later use and display.

A method of vapourising a sample of liquefied natural gas so as to retain the proportions of components of the liquefied natural gas on vapourisation, the method comprising the steps of: introducing liquefied natural gas into a liquid inlet (112) of a liquefied natural gas vapouriser (110); vapourising the liquefied natural gas at a vapourisation element (134) of the liquid inlet (112); and directing vapourised liquefied natural gas into a vapourisation conduit portion (120) directly after the liquid inlet, the vapourisation conduit portion (120) having a fall, thereby encouraging vapourised liquid natural gas to be directed against a flow direction of liquid or liquid-gas phase natural gas in the vapourisation conduit portion to encourage remixing of the vapourised liquid natural gas and liquid or liquid-gas phase natural gas A liquefied natural gas vapouriser (110) suitable for the above method is also provided.
