DEFINITION

Classification: 181/115

(under subclass 113) Subject matter including means to minimize adverse effects arising from the production of bubbles by the means for producing seismic waves in a fluid medium.

(1) Note. Some seismic sources produce seismic pulses by producing gaseous bubbles which may produce undesired or adverse secondary impulses. This subclass is drawn to means to mechanically control or compensate for such secondary bubble impulses.
