F. H. Gulliksen, Ralph N. Stoddard · Transactions of the American Institute of Electrical Engineers · 1935
Electronic tubes are being applied in rapidly increasing numbers in the solution of industrial control problems. A review of several of the most frequently encountered types of problems to which these tubes are being applied is presented herewith. These include photo-electric control applications, electronic relays, electronic regulators, and a welding timer for seam welding.
