Abstract
Abstract A separator system for use in removing liquid from a surface, which surface may be liquid or solid. The system consists of a pickup head, a separator, and an exhaust source which draws air through the pickup head and separator. The pickup head causes liquid to be entrained in the flow of air passing through it. The air and entrained liquid pass to the outer chamber of the separator where the liquid falls out and the air is fed through the inner chamber of the separator to the exhaust source.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
113 words
A separator system for picking up flow substance from a surface, comprising a. an exhaust means, b. an outer chamber having a top with a central opening connected to the exhaust means, having a side wall, and having a bottom, c. an inlet conduit having a first end which enters through the side wall of the outer chamber above a selected level, d. a pick-up head attached to the other end of the inlet conduit, and e. an inner chamber positioned within the upper portion of the outer chamber, the inner chamber having a tubular side wall surrounding the central opening and with an open bottom located below the said selected tubular level.
