181, Acoustics,
119+, for a seismic wave generation means coupled to a fluid.
367, Communications, Electrical: Acoustic Wave Systems and Devices,
25+, for the communication of information or intelligence in the form of acoustic waves traveling through earth and detected by electric signal handling means passing through a well bore and providing information pertaining to a characteristic or a location of discontinuities within the earth, subclasses 81+ for the communication of information or intelligence in the well bore in the form of acoustic waves traveling in a medium in the well bore different from the surrounding earth and providing information pertaining to a characteristic of the well bore or a location of discontinuities within the earth, and subclasses 86+ for the communication of information or intelligence in the form of acoustic waves traveling through earth and detected by electric signal handling means (a) passing through a well bore and (b) providing information pertaining to a
characteristic of a borehole or a location of discontinuities within the earth for electroacoustic borehole testing and wherein the intelligence pertains to the walls of the borehole and is obtained from a device which travels through the passageway and emits acoustic waves into a medium contained within the borehole (e.g., water, air, etc.) which are reflected from the walls back to the device and are detected.
