Description

This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1910 edition. Excerpt: ... to change the term "Static Induced Current" to "Hertzian Franklinization." It has also been suggested that the term "Franklinization with Indirect Sparks" would appear to be an improvement over the term "Morton Wave-Current." However, this does not at all appeal to the writer. Every electro-therapeutist knows exactly what is meant by the terms employed by Morton. D'Arsonval taught us nearly all we now know of the effects on the human body of high frequency currents. He gives the following actions: --yji Llji fig. 65.---Drawing of static current through a solenoid. (a) An entire absence of effect upon the general sensation and upon muscular contractility. (&) A marked influence on the vasomotor nervous system. (c) Marked assimilative and nutritive changes. Increased heat production in the body as well as increased absorption of oxygen and increased elimination of C02. There is increased heat dissipation without a lowering of the bodily temperature. In the year 1891, Nikola Tesla so forcibly called the attention of electrical engineers to the wonderful effects of the highfrequency currents that we often, at the present time, speak of "Tesla currents" when we really mean the high frequency currents. GENERATION OF HIGH FREQUENCY CURRENTS. In the generation of the high frequency currents we now have: --(a) The Morton method. (6) The d'Arsonval method. (c) The Tesla method. (d) The Oudin method. The foundation of these methods is practically that each one uses the disruptive discharge of a condenser to produce vibration, or the "to-and-fro" movement of the current. Much has been written lately upon the subject of high frequency currents. In fact, so many contradictory statements...show more
