(under subclass 282) Apparatus having means for producing compressional vibratory wave energy in a fluid medium in relation to or associated with the separating media to cause adhered constituents to be removed from the separating media, said waves being below, within or beyond the audible spectrum.
(1) Note. Pressure pulses in a fluid 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. Devices in which cleaning of the separating media is effected by pressure pulses of a gas will be found in subclasses 293 and 301+.
