DEFINITION

Classification: 204/196.15

With fluid inlet or outlet means used or protected:

(under subclass 196.1) Apparatus having at least one inlet or outlet or means for protecting an object having at least one inlet or outlet (e.g., object is a fluid heat exchanger or object protection means is a simple fluid pipe which may or may not be connected to a tank or vessel, etc.).

(1) Note. This subclass and the subclass indented hereunder are not intended to provide for an object protection means having a perforated anode unless the apparatus encloses at least a portion of the object and thereby forms inlet or outlet means for a fluid. The terms "inlet" and "outlet" find their meaning when applied to one or more openings in an apparatus which surrounds or contains an internal space (for holding or passing a gaseous or liquid medium) as would be the case with a vessel or pipe.
