ABSTRACT:
A device for discharging floating material from a supernatant layer floating on a carrier liquid in which the discharged material is moved along a discharge surface to an overflow. The device includes a carrier positioned above the supernatant layer. Blades are secured to the carrier for immersion in the supernatant layer in moving the layer toward the overflow. Means are further provided to move the carrier such that the blades supported by the carrier undergo movement through a trajectory with the trajectory of each blade or group of blades encompassing only a portion of the total displacement of the floating material by the movement of the carrier.
