The investigations described concern research designed to discover the feasibility of ultra sonic propagation in quartz media. The purpose of the investigations was that of determining the feasibility of bending optical quartz rod into various geometric forms for maximum delay time and minimum space requirements. A second purpose was to determine the feasibility of di rect propagation of Rayleigh and shear waves in the geometric form of the media studied, and the practical requirements for propagation. A third prupose was that of developing, theoreticay or practically, methods for obtaining specified characteristics in the transmitted and received wave form or pulse. A fourth purpose required the determination of the feasibility of pro ductively manufacturing the specific geometric form of quartz rod determined by the investiga tions. The goals of attainment established, initially, for these investigations were accomplished. Author
