(under the class definition) Apparatus having means for producing compressional vibratory wave energy in a gaseous fluid mixture to effect or enhance separation, the waves being below, within, or beyond the audible spectrum.
(1) Note. Pressure pulses in a gaseous fluid mixture generated merely by intermittent discharge of a gas are not considered to be compressional vibratory waves under this definition. However, compressional vibratory waves under this definition may be produced by intermittent discharge of a gas, as in a siren.
