RADIO BECOMES BILLION INDUSTRY Alternating Current Receiver Called Secret of Most of the Progress. NEW YORK (#)—Radio, having discarded its baby shoes for seven- league boots, looks in retrospect to 1928 as the year that put it in a class ::ordermg upon a billion-dollar indus- Catching its breath after the com- pilation of a mass of figures, it has concluded that its efforts for the last 12 months have developed a business estimated at gore than $750,000,000, with the alternating current receiver @s the secret of most of the progress. Self-contained sets that plug into the light socket without attention to batteries or eliminators have given the listener something for which he had been pleading since the early days of broadcasting. His eagerness to buy ‘was reflected by the fact that dealers experienced difficulty in keeping even tube supplies up to the demand. Revolutionary improvements in set Hesign were nil after the AC outfit got into maximum production. The few changes were due largely to refine- ments needed to iron out circuit kinks that developed with alternating cur- gent operation. Most of the elabora- tiop was in cabinet construction to Please the eye of the housewife. Better Instrument. Today the AC tube is a much better Anstrument than the early models. Dangers of burnouts due to fluctuating input voltages have been eliminated as far as possible. Appearance of a superpower tube Alled a need brought on by the dyna- mic speaker, which requires a separate current supply for its driving unit. It functions more satisfactorily when fed by a power amplifier. Another new tube, the shield grid, came into prominence last New Year. Ot created its greatest excitement among the fans building their own and numerous circuits for its use were brought out. Only one or two set manufacturers placed the tube in their products despite its high amplification factor without oscillation in a radio- ¥requency socket. The usual refinements in components and accessories kept step with the other advancements. Television Gets Start. __ Attention of the experimenter was gdrawn toward television after the de- cision ‘of a number of stations to run tests on both the broadcast and short ‘wave bands. Transmission of instan- taneous light is not yet adaptable to everyday use, but it was given a start. Broadcasting became a more im- portant factor when politics sought its aid to bring the candidate to the voter, spending approximately $2,000,000 for Nation-wide hookups and individual station broadcasts. Politics, which in- cluded the broadcasts of the national conventions, also was credited with in- creasing the sale of receivers. Chain broadcasting of sponsored programs from coast to coast became almost a daily event, and numerous features originating in New York found many listeners along the Pacific. Schools more.and more adapted ra- dio to the classroom, and many were the instances where it was used to aid in instruction. An important development in the industry centered around the greater effort at stabilization, mergers ‘of a number of important companies result- ing. As the year ends, leaders express the belief that the pulse of radio is| steadier than &t any .other holiday period of French President Anxious to Get U. S. on His Radio By the Associated Press. PARIS. — President Gaston Doumergue, an ‘enthusiastic ra- dio amateur, is anxious to get America on his receiver. He possesses three receivers in the palace of the Elysee, one in his dining room, another in the billiard room and a third in his study. They have enabled him to tune in all Europe, but he has not picked up signals from across the sea. A short-wave recefver is now being fitted up for his use. LECTURES BY RADIO PROVING A SUCCESS British Broadcasters Sell Million Pamphlets in Eudca- cational Campaign. LONDON (#).—Conclusive evidence has been obtained by the British Broad- casting Co. that its attempts to educate adults by means of broadcast lectures are proving a success. A million pamphlets, t0 be used in conjunction with educational talks, have been sold in the last 12 months. These pamphlets, costing one penny each, were forwarded in response to applica- tion by letter. Since eductaional bodies enlisted the aid of radio their membership has in- creased. One hundred and forty groups of listeners meet to hear the broadcast lectures and afterward discuss and de- bate them. An official of the company who under- took a tour of the country districts to obtain first hand evidence of the inter- est in educational broadcasts learned that farm workers in the agricultural county of Sussex read and enjoyed Plato’s “Republic” after hearing a broadcast talk on philosophy. Libraries throughout the British Isles are advised in time to enable them to order advance stocks of books on suk- jects about to be broadcast. PROGRESS IS MADE BY SIGNAL CORPS Chief Officer Notes Two Contribu- tions to Aircraft Radio in Report. ‘The “most astonishing progress” made by the Signal Corps of the Army dur- ;;:J the last year has been in the radio d, Maj. Gen. George S. Gibbs, chief signal officer, declares in his annual report. Described by Gen. Gibbs as “two notable contributions to aircraft radio,” the Signal Corps has developed a new receiver that will supersede the stand- ard recelvers now in use on Army air- craft, and a double-voltage, direct en- gine-driven generator for use on planes. The new recelver is considerably lighter in weight, occupies much less space, is rugged and receives continuous wave as well as tone modulated and radio tele- phone signals. The direct engine-driven generator was jointly developed by the Signal Corps and the Army Air Corps. It eliminates the necessity of supplying & dynamo with each radio set, and effects a saving in weight and cost and in- creases the dependability of operation, the engineers say. “These two accomplishments have been effected at the Signal Corps air- craft radio laboratory at Wright Field, Qhio; and have ‘been’ greatly facilitated the Air Corps in making available as a flying laboratory a three-motored transport plane,” said Gen. Gibbs. ‘“So 1 THE SUNDAY STAR, WASHINGTON, D. C. DECEMBER 23, 1928—PART 1. RADIO IS EXPECTED TO OPEN NEW FIELD Development of Three Devices in Britain to Enlarge Industry. LONDON (#)—Inventions now un- der test are expected to open an entirely new field in radio in Great Britain in linking the motion picture industry with ‘broadcasting. The development of three devices is reported: An apparatus for broadcast- ing moving pictures, a device for syn- chronizing film§ with music and a re- cording machine which can be attached to any radio receiver which will record the incoming message on a ribbon so that it can reproduced at any time through the same radio set. The production of sound films in Europe seems to be assured. Many companies have been organized, and various experiments in the process of making sound films have been tried out. Great_Britain has four talking and sound film companies. Three separate systems are employed in making “talk- fes” in British studios—the De Forest, the separate film record and the disk system. The De Forest method is an adaptation of the photo-electric cell principle. In addition to these methods there is an acquisition from Germany, an electro-magnetic process operated by a fine wire which runs independently on an aluminum spool beside the film. In Germany a combine of experts with capital of $2,500,000 has perfected sound film systems. This syndicate has; acquired the patents of several inventors and is engaged in combining the best points of all the inventions. Two of the most important electrical com- panies have founded a new sound film company named Klangfilm. AMERICAN BAR PLAN RADIO LEGAL ADVICE Association.

Capt. Otho Fulton, well known British ventor and experimenter, transmitted hotographs to the S. S. Aquitania from he gowertul Daventry ' radio station mear here recently. Radio messages re- celved from the steamer report that facsimile pictures were received aboard the vessel when it was 650 miles off the coast of Great Britain. Five pictures were transmitted di the powerful broadcasting. station. first picture sent was that of the ieen, followed by likenesses of the {Prince of Wales, the Duke of York, the rehbishop of Canterbury, Prime Min- ter Baldwin and Lord Hailsham. .. The photographs transmitted from ventry were first reproduced by pho- them through a finely ruled #creen upon & thin plate of chemically itreated copper, it was explained. The jcopper was then placed upon & revolve ing metallic cylinder, the needle, fol- lowing the finely ruled lines like a graphophone needle, producing a low uneven humming sound which was $ransmitted over the broadcasting ap- paratus to the recei station. Aboard the Aquitania, it was ex- jplained, a similar cylinder revolved in | Perfect synchronization with the send- ing cylinder. The synchronization was reflected upon each revolution of the cylinder. This reflection automatically (electromagnetically as Capt. Fulton says) is one of the most important fea- tures of the apparatus. Upon the receiving cylinder is placed a piece of paper wet with potasstum bromide solution, and upon this ‘paper the receiving needle traces the image transmitted. The process requires about three minutes to transmit each picture. Reports from the vessel indicate the reception of all the pictures was excep- Xionally clear. Capt. Fulton sees his invention not only as an interesting device for the radio fan, but as likely to be enor- mously valuable for commercial utility. The experts who engineered the transmission of the pictures to the Aquitania declare that the success of the experiment will make the picture- transmitting device extremely valuable for the sending of facsimiles of weather ”‘%’, to ships at sea. experiment was conducted by P. E. Pykett, radio expert of the oompyany promoting Capt. Fulton’s invention under the name of Fultograph.
