Legislation and Acoustics Topics at March RM A Meeting Dr. John Winton, Acoustical Engineer, Gave Illustrated Address on "Sound Generating Surfaces" — Legislation in Washington Discussed Developments in radio, both in legislation and in acoustics, were subjects discussed at the monthly luncheon of Radio Manufacturers' Association on March 20th, at the Hotel Commodore, New York. Dr. John Winton, acoustical engineer, who has been identified with some of the most important steps of radio progress, gave an illustrated address at the RMA luncheon, which was presided over by Hugh H. Eby, of Philadelphia, an RMA director. "Sound Generating Surfaces" was the subject of Dr. Winton, who reviewed over a century of pioneering experiments in acoustics from which the modern loud speaker has developed. These experiments, Dr. Winton said, dated back to 1829, including tests of metal bells, one of the many types of sound transmission surfaces. Mathematics of vibrating surfaces, as well as acoustics, which are now incorporated in the modern loud speaker, according to Dr. Winton, go back at least to 1839. He reviewed the developments in telephone, phonograph, and other sound transmitting and radiating devices and stated that, peculiarly, some modern manufacturers were basing their new products on acoustic principles as old as fifty years. How representatives of the radio industry had been opposing new radio legislation in Congress, threatening the radio public and the industry, were detailed by Bond P. Geddes, executive vice-president of the RMA. The new legislation was rushed through Congress, Mr. Geddes stated, without any one of the radio industry or the radio public having a word before either House or Senate Committee. None of the radio interests able to give their technical or other opinion on the effect of the legislation upon the industry or the public was heard. Protests of radio industry representatives to individual members of Congress, Mr. Geddes stated, had been followed by a compromise on the so-called "equal" distribution of broadcasting facilities, which actually is unequal and inequitable both to the radio public and the broadcasting interests. "Politics of many varieties, from Ku Klux Klan to the Shipping Bill, all figured, and unfortunately, in the new radio legislation," said Mr. Geddes. "The compromise probably will read into law an unfortunate principle that radio broadcasting facilities should be allocated from the transmitting end, rather than the public reception end. However, the compromise is infinitely better than the original drastic and unworkable legislation proposed." That within a week the Senate will take action on the confirmations of radio commissioners and give the radio public and the industry something it had been denied for a year — a functioning commission — appears probable, Mr. Geddes said. during the past four days, April 2 to 5, under the auspices of the Federated Radio Trade School and the Amateur Relay Clubs of the city, was a decided success. Manufacturers of radio receivers, parts and accessories from all parts of the country had displays, featuring chiefly the newest AC developments. One entire section of the exposition hall was devoted to a series of electrical stunts and radio experiments, including television and short-wave operation. United Co. Announces Motor for Portables For several years F. F. Paul, president of the United Air Cleaner Co., has felt that the one outstanding need in the phonographic field was Radio Exposition Held in Detroit Detroit, Mich., April 6.— The radio exhibition which was held at the Convention Hall United No. 2 Motor a good small motor designed exclusively for portables. This idea, combined with the engineering activities of the United Air Cleaner Co. over a considerable period, has at last resulted in the new United No. 2 Motor — a motor made to (it the distinctive needs of portable construction. The new motor is silent, and though of necessity small, has a strong, even pull, operating with a noiseless worm-gear wind. It has a number of exclusive United features which especially adapt it for use in portables.
