Abstract :
C. R. Hanna (Westinghouse Electric and Manufacturing Company, East Pittsburgh, Pa.): This paper on the design of the familiar metadyne is very interesting. Where regulation accuracy requirements are not too great, this device may be used, but as the author points out, a nice balance between the compensating field and the armature ampere turns due to load current is required for high amplification, and this balance, of course, is subject to definite practical limitations.
