Industrial applications of amplidyne generators

ACONSIDERABLE number of “amplidyne”^∗ generators^1,2 have been applied in conjunction with other electrical apparatus to industrial processes within the past few months. A summary of these applications indicates that the amplidyne generators are of particular value in conjunction with so-called “closed-cycle” control systems. A closed-cycle system may be defined as one in which the controlling agency is actuated in part by some function of the final output in such a manner as to minimize any deviation of this output from an ideal value.
