About this book
Induction Coils, How to Make, Use, and Repair Them by H. S. Norrie covers Ruhmkorff, Tesla and medical coils, Roentgen radiography, wireless telegraphy, and practical information on primary and secondary battery. The section headed Insulations and Cements begins by considering compounds for apparatus intended to operate under the influence of high tension currents. Instructions for glass condensers describe alternating tinfoil and glass, clamping the stack securely, and placing cloth above and below to prevent pressure from cracking the glass.
The account of coherers describes adjustment by advancing or receding electrodes and altering the quantity of filings, while noting difficulty in guarding against external electrical disturbances. The mercury vibrator described for almost every large coil has a pivoted arm, a soft iron armature at one end, and an adjustable platinum point at the other.
