Compounds which are strong organic bases do not stabilize capacitors. Quartz Crystals for Electrical Circuits.4 R. A. HEISING. This book is a compendium of information, both theoretical and practical, on quartz crystal plates, their design and manufacture. 

It embodies the vast experience of the Bell Telephone Laboratories in research and in manufacture of quartz crystals. It originated from a series of lectures given by the members of the Laboratories technical staff who had carried out the early studies and developments in this field. By this means, engineers were trained for the immense expansion in crystal manufacture required to meet the demand of our military forces during the War. These lectures have been reorganized and rewritten, and are published together in this comprehensive book. Articles covering some of the various chapters have appeared in the Bell System Technical Journal. The treatment covers in full the theory and practice of the preparation of quartz crystals, the instruments used, including new types developed for special purposes, the problems encountered in the various uses of quartz crystals, and the full details of the methods devised for their solution.
