Fluid handling

SECTION I - CLASS DEFINITION

This is the residual class for fluid material handling, and takes processes, systems, combinations, subcombinations and certain elements pertaining thereto not otherwise classified.

Fluid materials include gas and liquids primarily, but the handling of other flowable materials, as fluent granular solids, is also found.

Handling for this class comprises the transfer of fluent material by flow, as by confining, directing, causing and/or controlling the flow, and includes making the material available for flow or separating a smaller from a larger body of fluid material, as by tanks, containers, receivers, traps, etc., or pipes or conduits, with or without siphons, pumps, pressure or displacing fluids or other flow imparting means.
