  • Patent number: 3935104
    Abstract: An automatic foam remover for a substantially rectangular flotation tank in which during operation thereof a layer of foam accumulates on the top surface of a liquid body therein, said foam remover comprising a hollow beam extending horizontally across the top of the tank and being movable back and forth between two parallel side walls of the tank by means of motor-driven endless chains mounted on the tank and operably connected with said beam, the hollow interior of which is in communication with a source of vacuum. Said hollow beam is provided with a longitudinal bottom slot through which a vane which is pivotally mounted within the hollow beam, extends downwardly through said layer of foam, whereby said vane during the movement of the beam is alternately forced into engagement with the two edges of said slot and thereby causes the layer of foam to be subjected to the action of the source of vacuum alternately at one side of the vane and at the other side thereof.
