Ill DEVICES OF use lira Electricity Authority Declares De-clares Few Years Will Bring Great Advances. Wartime electrical discoveries and inventions in-ventions will be of great benefit during the days of peace, forming a basis for : even greater developments, Dr. Frank B. Jewett, chief engineer of the Western Electrical company and former civilian member of the antisubmarine board of the navy, said yesterday upon his arrival in Salt Lake. Dr. Jewett was a lieutenant colonel in the signal reserve corps of the army during dur-ing the war and was decorated by the war department for his aid in the development devel-opment of electrical devices. He will address ad-dress members of the American Institute of Electrical Engineers at a meeting to be held at 8 o'clock thie evening at the Commercial club on "Some Wartime Developments De-velopments in Electrical Communication and Allied Fields." In discussing the use for wartime electrical elec-trical inventions, he said: "The submarine sub-marine detectors developed during the war will be of great value In the shipping industry in avoiding collisions in the dark and fog and in the locating of submerged harbor bells." He pointed out that many of the losses of life at sea are caused by the failure of ships to hear foghorns. Use of the submarine detector will tend to eliminate these disasters, he said. "If there come a time when the airplane air-plane is used for commercial purposes," he declared, "the wireless telephone developed de-veloped during the war will be a means of communication between planes. It may also be used to communicate messages mes-sages from the machines to the ground. Radio telephony may be used, also, between be-tween ocean ships and the land." That the field of electricity is In Its infancy was the opinion expressed by Dr. Jewett. The next few years, he said, will bring important developments In power generation and control, communication, and In electrically operated machinery. Speaking of remarkable advances in the perfection of electrical devices during the war, Dr. Jewett said that It was possible, with the use of sound-ranging apparatus, to determine within a radius of fifty yards the position of a big gun. Sound ranging was one of the Important discoveries discov-eries developed in the war, he said. All apparatus for range finding was manufactured in the laboratory of the Western Electrical company. Dr. Jewett Is speaking before branches of the American Institute of Electrical Engineers in the west.
