Ainlay, J A

A floating, seagoing skimmer has a separating chamber communicating at this lower end with the body of water into which it is placed. A weir at the front of the chamber has a forwardly extending curved surface which terminates in a skimming edge and a rotating vaned impeller whose path of movement is disposed relatively closely to the curved surface of the weir, so as to carry the combined floating liquid and water over the weir and into the separating chamber. The top of the weir is substantially above the water surface so as to create a hydrostatic head for causing water flow out of the bottom of the chamber and the number of vanes in the impeller. Its speed of rotation and its depth of penetration are such as to move the combined floating liquid and water with a minimum of turbulence. The skimming edge ahead of the weir is adapted to be held somewhat below the interface of the floating liquid and water surface. (17 claims)
