mm RADIO DICES 1 April 21, 1923 DEFOREST COMPANY BOUGHT BY JEWETT DR. DEFOREST TO REMAIN AS ADVISOR Possible That Newly Purchased Corporation Will Combine with Jewett Company (Special to RADIO DIGEST) DETROIT, MICH. — Outright purchase of the entire business, good will and patents of the DeForest Radio Telephone and Telegraph Company was announced todav by President E. H. Jewett of the Jewe"tt Radio and Phonograph Co. of Detroit. Associated with Mr. Edward Jewett in the purchase are Theodore Luce, former Detroiter now associated with the New York and Chicago bond house of A. C. Allyn; Frank W. Blair, President of the Union Trust Co. of Detroit; H. M. Jewett, President of the Paige-Detroit Motor Car Company; and several other capitalists and Radio experts. Possess 181 Patents As a result of the purchase, the Detroiters come into possession of 181 Radio patents, among them the basic rights to the three-electrode audion bulb, which is an essential part of every long distance Radio receiving or sending set. All other tube manufacture is conducted by virtue of license under DeForest patents. Among the other patents are several others covering Radio equipment in general use, as well as a large number representing more recent development and research by Dr. Lee DeForest, and embodying startling new developments in the Radio field. The purchase also includes the fine new plant of the DeForest Company at Jersey City, the largest individual plant in the world devoted solely to Radio manufacture, at which DeForest inventions are manufactured commercially. No announcement was made of the amount of money involved in the transaction. DeForest to Remain. Dr. DeForest remains with the company under a long-time contract as consulting engineer and is now, according to Mr. Edward Jewett, giving a large share of his attention to the perfection of equipment by which the human voice is synchronized and reproduced in connection with moving pictures, thus adding a startlingly widened range of interest to the hitherto silent drama. "Dr. DeForest is really the father of modern Radio," commented Mr. Jewett in discussing the transaction. "Without his contributions to the science, commercial Radio would not be possible. Like most inventive geniuses, the commercial side of his work has been distasteful and he is glad to turn over this factor to our group. It is our intention to make the name DeForest as significant to the general public of the best and the most advanced in Radio, as it stands today among the experts. In accordance with this policy we will put behind the DeForest products every bit of Detroit enthusiasm and merchandising ability within our power. May Consolidate "The affairs of the DeForest Company will be administered from Detroit, though we have no plans for any immediate change in the personnel or operating methods of the Jersey City factory. "Will the DeForest Company be eventually combined with the Jewett Radio and Phonograph Company?" Mr. Jewett was asked. "Such a combination is more than possible," replied Mr. Jewett. "It is also possible that the DeForest purchase may eventually result in a large addition to the manufacturing facilities of the Jewett plants at Allegan." RUM RUNNERS RADIO (Continued from page 1) rum-runners, as told in Montreal, prove it to be complete in every respect. The place where the sending station is located is the headquarters o'jf. the large booze ring. The rum-runner reports to this station, whereas formerly lie was obliged to communicate with every town along the line by telephone. The minute the report as to location and time is received at the Radio station, it is broadcast to every station. The time, meaning the exact hour at which he has paid for his protection in every town, a proceeding observed before the trip is attempted, is then arranged according to the time made on the trip. May Revolutionize "Profession" "So far," declared one rum-runner, "it has worked fine. I have made two trips on the Radio schedule and got through without a hitch. All the men at the stations are experts in Radio and have no trouble in picking up all the signals. In fact, it is the most complete working system that I ever been connected with, and it looks as if it is going to revolutionize the 'profession' of rum-running." Radiograms can be exchanged between vessels and Syria by means of the Alexandria Radio station. The rate is the same as the rate for Egypt increased by an additional rate of 30 centimes per word.
