Abstract: A panel having a panel surface and an edge pair of mutually opposite complementary panel edges provided with complementary locking elements. The complementary locking elements are configured such that, when two panels are assembled, both a locking action of the panel edges in a direction perpendicular to the panel surface and a locking action preventing the panels from moving apart is achieved underneath a visible joint by the assembled complementary locking elements. The panel edges with the locking elements have an upper portion and a lower portion, relative to thickness of the panel. The locking elements are arranged and configured in the lower portion. The upper portion forms the upper joint region, including the visible part of the joint. The upper portion on each panel edge of the edge pair has a chamfer which, when two panels are assembled, forms a depressed joint. The chamfers of the complementary panel edges are different sizes in the upper portion.

Abstract: What is proposed is a centrifugal droplet separator for separating liquid droplets out of a feed gas stream comprising them, with a vertical longitudinal axis and circular cross section, with a jacket (1) and with hoods (2) at the upper and lower ends of the jacket (1), with tangential supply (3) of the feed gas stream comprising liquid droplets at the jacket (1) and with an outlet stub (4) for the liquid separated out in the centrifugal droplet separator in the region of the lower hood (2), and with a gas outlet stub (7) for the gas stream cleaned in the centrifugal droplet separator in the region of the upper hood (2), wherein two, three or more inlet orifices (9) arranged symmetrically on the circumference of the upper hood (2) for tangential supply of cleaning liquid are provided in the same direction as the supply of the feed gas stream comprising liquid droplets.
