Since Lawyer Richberg stepped down from NRA in 1935, he has been little heard of. But he has been so well remembered by Transamerica Corp., Ford, American Rolling Mill, and other great corporations that he probably pockets a cool half million a year from his law business. The firm of Davies, Richberg, Beebe, Busick & Richardson is one of the busiest in the Capital and one of its principal assets is Partner Richberg's erstwhile intimacy with Franklin Roosevelt. Although he still sees the President frequently, Donald Richberg's advice no longer carries much weight, for the anti...
...This fact, however, he kept a close secret from his business associates. His stories were published under the pseudonym of William March. His literary output and reputation, though not his literary earnings, increased rapidly. In 1933 appeared a War novel, Company K; in 1936 his powerful novel of Georgia mill hands, The Tallons...

...Hardinge's son, Harlowe, vice president and general manager of Hardinge Co. of York, Pa., studied his father's "ball mill" in operation. There was a certain rate of feeding in ore at which it performed most efficiently, and that rate could be estimated by sound. When the feed was too slow, the noisy clatter of the mill increased; when too fast, the sound was muffled. Workmen were trained to listen for these changes in sound and manipulate the ore flow accordingly. But Harlowe Hardinge noticed that the listeners' judgment was likely to vary as much...
Harlowe Hardinge therefore invented a sensitive "electric ear" to replace human hearing. A parabolic reflector picks up the sound from the mill, focuses it on a microphone. If the sound is at the most efficient level, the microphone current keeps a galvanometer balanced between two contacts. If it rises or falls as little as one-quarter of a decibel, the galvanometer makes contact on one side or the other, closing a circuit which starts or stops the flow of ore as the situation requires. More than 75 of these electric ears are already...
