Abstract: An electronic device is provided, which includes a printed circuit board (PCB), a housing receiving the PCB and including a through-hole connected to an outside of the electronic device, an electronic component connected with the PCB and accessible from the outside via the through-hole, and a sealing member disposed between a surrounding of the through-hole and the electronic component and shaped as a closed loop. The housing includes a sealing area disposed inside the housing along the surrounding of the through-hole and contacting the sealing member, a rib projecting towards an inside of the housing from an end of the sealing member, supporting the electronic component, and limiting movement of the electronic component by an external force, and a recess formed in an area of the rib, at least a portion of the recess that is flush with a surface of the sealing area.

Abstract: An apparatus for the flocculation of solid particles in a solid-liquid stream including an enclosure, an upwardly converging flow diverter defining a first zone and a second zone within the enclosure, and a solid-liquid stream inlet into the first zone of the enclosure at or towards the bottom of the first zone in proximity to the lower region of the flow diverter, the upwardly converging flow diverter having an upper opening for fluid communication between the first zone and the second zone. The apparatus is preferably a feedwell for a separation device for separating solid particles from a liquid in a solid-liquid stream.
