Abstract :
The following bibliography relating to ultrasonic delay lines has been compiled as a useful guide on their theory, design, and applications. One can consider the material in four classifications; first, references of a general nature, descriptive or analytical, dealing with the principles of wave propagation in bounded elastic solids and with the basic elements of ultrasonic delay lines and the eqUivalent circuit; second, material re~ating to the means by which ultrasonic waves are generated, the electromechanical transducer; third, material relating to the transmission medium, principally vitreous silica, aluminum, magnesium, iso-elastic metal alloys, and, to some extent, mercury; and finally; references on applications of ultrasonic delay lines as information storage elements in digital computers and in radar indicators and as time calibration devices.
