    • An imaging system for and method of imaging product in a product flow (F), the system comprising: an illumination unit for illuminating product in the product flow with illumination at first and second, different wavelengths or ranges of different wavelengths; a detector unit (15) for detecting reflected illumination from product in the product flow, wherein the detector unit comprises first and second line array detectors, the line array detectors (17a, 17b) each comprising a plurality of pixel elements and extending as lines across a width of the product flow, one line downstream of the other, whereby product passing a pixel element of the first line array detector passes a corresponding pixel element of the second line array detector; a control unit for triggering the first and second illumination sources to flash sequentially at a scan rate corresponding to the flow rate of the product flow; and an image processing unit for successively reading the pixel lines of the first and second line array detectors and constructing images of the product at each of the illumination wavelengths or ranges of illumination wavelengths.

    • A valve device is disclosed for controlling the delivery of gas from a pressurised source, suitable for use in a pneumatic ejector in sorting apparatus. The device comprises a housing defining a valve element chamber with an input for connection to a source of pressurised gas. A body (50) in which at least one output duct is formed, has an end face in the chamber with a valve seat thereon surrounding the output duct or ducts (56). A valve element (52) overlays the valve seat, and means are provided for moving the element between a closed position in engagement with the valve seat and an open position spaced from the valve seat. Additional abutment surfaces can be provided for engagement with the valve element on closure. At least one pocket (57, 58) is formed in one of the juxtaposed body end face and the valve element, which pocket forms a cushion of gas as the element moves towards its closed position. The pocket or pockets or additional pocket or pockets can be formed on one or more abutment surfaces spaced from the valve seat. Similar pockets can be formed on surfaces in juxtaposition to form a gas cushion on movement of the valve element to its open position.
    • 公开了一种用于控制来自加压源的气体输送的阀装置,适用于分选装置中的气动喷射器。 该装置包括限定阀元件室的壳体,其具有用于连接到加压气体源的输入。 其中形成有至少一个输出管道的主体(50)在腔室中具有围绕输出管道或管道(56)的阀座的端面。 阀元件(52)覆盖阀座,并且提供装置用于在与阀座接合的关闭位置和与阀座间隔开的打开位置之间移动元件。 可以提供附加的邻接表面用于在关闭时与阀元件接合。 至少一个口袋(57,58)形成在并置的主体端面和阀体中的一个中,当该元件向其关闭位置移动时,该口袋形成气垫。 口袋或口袋或附加口袋或口袋可以形成在与阀座间隔开的一个或多个邻接表面上。 可以在并列的表面上形成类似的袋,以在阀元件移动到其打开位置时形成气垫。
