  • System for transmitting ultrasonic energy through core samples
    Patent number: 4380930
    Abstract: A system for measuring ultrasonic (50 Khz-10 Mhz) velocity and attenuation in core samples employs transmitting and receiving transducers for generating and receiving ultrasonic energy in a core sample. The transducer and core sample are contained in a high pressure cell. The transducers are isolated from the high pressure of the cell by suitable housings, allowing the transducers to operate at ambient pressure.
