DEFINITION

Classification: 55/309

(under the class definition) Apparatus provided with means (1) to permit total flow of the system fluid directed through the apparatus to avoid the separating means, or at least one stage of serially arranged separating means, (2) to admit ambient air to the apparatus through other than the normal inflow path of fluid to be separated, or (3) to permit discharge or escape of system fluid to the ambient air through other than the normal gas effluent path.

(1) Note. Pressure relief is not a matter of mere multiple discharge paths or inlet paths, but some modified arrangement for flow which responds to excessive or back pressures.

(2) Note. A bypass means under this definition does not include a mere movably or removably mounted separator means, but does include a separating means which, in response to certain gas pressure or flow characteristics, is moved out of its normal use position to provide for a bypass therearound.
