(under the class definition) Apparatus provided with (1) means to admit a fluid differing from the working fluid* in some essential characteristic (e.g., temperature, pressure, composition), or (2) at least two inlet means admitting the same working fluid* into the apparatus, one inlet means different from the other in some essential characteristic, (e.g., size, attitude or position relative to a fixed point or axis).
(1) Note. In order to qualify under this definition, the diverse inlets or the diverse fluid must enter the apparatus upstream of all disclosed runner* stages.
