Chapter I: Quartz crystal applications

THIS paper is the first one of a series of papers dealig with quartz crystals, their applications in oscillators, filters, and transducers, and the methods of producing them from the natural crystal. This series was prepared first to make available to the Western Electric Co. and other manufacturers of quartz crystals some of the specialized knowledge on these subjects that has been acquired at the Bell Telephone Laboratories. Sufficient interest has been expressed in this series to make it desirable to publish them in serial form.
