Abstract: Apparatus for reducing dust emissions from particulate commodities such as wheat or coal using a curved loading spoon connected to the discharge from a loading spout. The curved loading spoon turns particulate commodities delivered at a rate above a predetermined delivery velocity against a curved outer wall causing dust arising from the particulate commodities to be re-entrained within the commodities as they are diverted from a straight path by the curvature. Also described are an optional flap designed to rest just above the surface of the commodities stream adjacent the outlet, and a converging duct located upstream of the curve loading spoon and arranged to direct commodities against the curved outer wall adjacent the inlet.

Abstract: There are disclosed methods for inhibiting dynamin-dependent endocytosis in cells comprising treating the cells with an effective amount of a compound of formula (I), or a dimeric tyrphostin, physiologically acceptable salt, or prodrug thereof. Compounds useful in the methods described are also provided. The inhibition of dynamin-dependent endocytosis of cells is applicable to the treatment of epilepsy and neurological disorders and conditions.

Abstract: Method and apparatus for the separation of particles from a particulate suspension. The apparatus comprises a rotating flotation drum (10) with a feed distribution chamber (13). Particulate suspension feed enters the chamber through a delivery pipe (20). The feed passes through holes (21) into the particle collection chamber (22). Air is passed into the particulate suspension through a porous inner wall (29) and a froth is generated. The froth and particulate suspension pass into a froth cleaning chamber (32). The froth is washed by being sprayed from a washwater distribution pipe (47). Froth is removed from the drum by a froth scraper (49) through a froth removal chute (50). Unfrothed particulate suspension passes through openings (40) into a weir chamber (41) and is removed through a launder (45).

Abstract: A method of operating a plurality of minerals separation flotation cells (1,2) each having a feed inlet (9,14) a values outlet (11) and a gangue outlet (12,15), and each flotation cell being located at substantially the same level. A feed box (3) is located alongside the flotation cells (1,2) which are connected in series such that the outlet (7) from the feed box (3) is connected via a first pump (8) to the feed inlet (9) of a first flotation cell (1), the gangue outlet (12) from the first flotation cell (2) is connected via a second pump (13) to the feed inlet (14) of the next flotation cell (2), and so on until all of the flotation cells are connected in series. Each flotation cell also has a recycle outlet (19) from the lower part of the flotation cell arranged to return a predetermined proportion of the material flowing through that flotation cell to the feed box (3).

Abstract: An apparatus for use in photogrammetry is disclosed having two spaced-apart parallel scanning zones to which the photographs of a stereoscopic pair of photographs are mounted.A carriage mounted optical scanning system is provided for scanning the two scanning zones and for projecting images of the respective zones to a binocular viewing system, and a secondary optical system is provided, preferably on the carriage, for superimposing reference marks on the projected images.The scanning system is arranged in such a manner that simultaneous scanning of the two scanning zones can be effected in a first direction parallel to the scanning zones, and independent scanning of the two scanning zones can be effected in a second direction which is parallel to the scanning zones and orthogonal to the first direction. Also, the apparatus is adapted to permit relative scanning of the two scanning zones in the first direction or for optically moving the reference marks relative to one another in the first direction.
