Abstract: The present disclosure relates to an air supply duct for a vehicle, the air supply duct comprising a housing, the housing having an inlet adapted to receive air from outside of the vehicle and an outlet adapted to convey the air to a vehicle climate control system, and a cowl arranged inside the housing, the cowl being adapted to direct the air along an air path, such that the air path changes direction within the housing. The cowl has a curved form adapted to form an inner curve of the air path. Further, the cowl comprises a precipitation collection means arranged to collect precipitation borne by the air from the outside of the vehicle and to remove the precipitation from the air. The disclosure also relates to a vehicle comprising such an air supply duct.

Abstract: The present invention relates to a froth flotation mechanism located in a flotation cell, comprising a directional element suspended from the lower end of a hollow shaft extending to the lower section of the cell and vertical vanes attached to said directional element, which extend above and below the directional element and horizontally beyond the directional element. The substantially horizontal circular plate of the directional element is symmetrically attached around the shaft at its centre and the outer edge of the central plate is bent downwards to form the lap of the guiding part. The gas spreading plate is located on the inner side of the lap. The flotation cell is comprised of a cylindrical lower section, a middle section located above it in the form of a truncated cone widening upwards, and a cylindrical upper section attached to the top of it.
