RADIO PROGRESS IN U.S.

NEW DEVICES EVOLVED.

. (PBOM ODB OWIT COBBEBPOJIDEICT.) SAN FRANCISCO, January 23., Important improvements are being chronicled almost every day in radio telephony development, and one that has particularly struck the public fancy was that which came to light early m the New Year.

Some of the United States' Government Cabinet Ministers, including Vice-President Coolidge, Secretary of War Weeks, and Secretary of the Navy Denby, made Christmas greetings into a new recording device whereby the vibrations of their voices were photographed «pon a strip of film. Subsequently that film was run through another invention , tne pallophotophone, at the General Electric Radio Station at Schenectady, not far distant from New York city and their speeches were broad°ro Z* 11 oyer the United States. / Kadio sets in Mew York picked up the words as clearly as though the speakers had actually been present at bcnenectady. I t was the first official use of the pallophotophone, which had rust been perfected bv the General T +l° Lom P a »y's staff of engineers. in the recording instrument the voice viorations actuate a tinv beam of light 3 C s t r ! kes t]l e moving strip of film and registers theieon a thin, wavering nJlf\ TVhen the fil '» is developed it *?* . an and fed into the sending device. There the procedure is reversed, and the lines on the film are transformed back into snund vibrations.

Tlio pallonhotophone. scientists believe, will do aw.iv with mnnv diflftVu]tws now met with in broadcasting. Heretofore it has often been dimwit to obtain artists for r*dio concerts because nf the time and inconvenience required for them to pr-ceed to and from the broadcasting stations.

Speeches by Machinery. With the new invention, film records can be made at the artist's convenience and broadcast at any subsequent time from any station properly equip-

Additional copies of the film may also be made, and the speech or musical selection be sent from widely-separated stations simultaneously. In this way it would be possible for one person's voice to carry to every part of the globe at a given moment. In. his address broadcast from Schenectady, Vice-President Coolidge sent a Christmas greeting to the American people Secretary Weeks spoke to the ex-service men and urged them to continue to interest themselves in the problems of national defence and the military training of the younger generation.

Secretary Denby's greetings to the men of the navy were listened to by all ship and shore stations within range. Many interesting applications of the pallophotophone have already been made, and a few possibilities can be briefly outlined as follows: It "makes possible the talking motion-picture, for a film of the normal width, both sound and action can be recorded simultaneously ._ and projected with absolute svnchronism. It is practically unlimited as to the length of record it can make and reproduce, and is, therefore, suitable for recording speeches, debates, concert programmes, in the taking of evidence, and for any purpose where a lengthy record of sound is required. It can be duplicated and used as a film photograph and applied in. radio telegraphy, in producing wireless signals and for radio amplification. Radio Funeral. •

"We commit this body to the deep. . . . ." "While the crew of the stormtossed little freighter Hatteras stood with bared heads about the body of their dead captain, the steamship President Adams, 240 miles away, transmitted by radio the solemn words of the Church of England burial service, according to a dispatch from New York. ~

They had ho Bible or' Book of Common Prayer aboard the Hatteras, and none knew the ritual. But one more captain had eiven.his life to the sea, and they wished that his burial should not be devoid of honour, so they appealed to the big American liner, the President Adams. The service was dictated at the height of a furious gale, and word by word the radio operator of the Hatteras relaved it to the chief officer, who performed the committal ceremony. ' *

This firnnee story of the sea was related when the Present Adnms arrived in the port of New York after one of the roughest trips in her historv.

Captain Penderhurv said the Hatteras fnt in toii"h with his ship bv radio 'n mid-Atlantic, statin? that tTip captain. A. Mathews, was dnn<rerouslv ffl, Tl>e left. Virmr,i n . on December 24th, for Belfast. For four doys the weather was so rough that Captain Mathews, according to the message from the Hatteras, had stood almost continually on .the bridge. He was constantly drenched to iho skin, and got little sleep. On the fifth day he was stricken by pneumonia, and succumbed after his terrible exposure to the gale. I Chickens like Radio. Chickens like radio music, and owners of the birds have been advised in a telegram from St. Paul, Minnesota, that installation of radio outfits will more than repay the outlay I This, at least, is the contention of Jacob J. Irvine, of iWinlock, Washineton, who arrived in- St. Paul and told his experiences. By providing the hen coop with a radio set the hens produced better results. Irvine solemnly declared to his astonished listeners. Irvine stated that he had installed a radio set in hia_chicken house, which shelters 6000 hens. A survey revealed that the number"of eggs laid had increased from an average of 58 to 78 for every 100 hens.

Radio as an aid to surgical operations was employed for the first time in Minneapolis medical circles when a radio receiyins set was attached to the ears of a woman patient who underwent a Caesarian operation at a hospital in that citv. Local anaesthesia was- applied to the patient and the radio set adinsted. As the surgeons went about "their work the of the patient was soothed and districted from the operation by the strains of music. Mother and child both came out of the operation in fine condition, and were resting easily, it -was said. A band concert was given exclusively for the patient. Foreseeing millions or listeners, the bulk of them of college age. the National Radio Chamber Commerce of America, is developing a plan to establish rad'o extension bourses in American colleges and universities. In radio, education has found a new and powerful ally, said announcement issued at the Chamber's headquarters in New York- „ England and Germany, it was stated, are planning to broadcast university extension courses. "Several prominent institutions of learning in the United States hare made a beginning fh this. direction" the announcement continued, "and their reports of the encouraging success attending their efforts

show us that the possibilities of the new method are not underestimated. "Sixty other educational institutions are broadcasting educational and musical programmes, forty-seven of them being colleges and universities. The combined area nominally covered by these institutions has been estimated to be .seven or eight times the total area of the United States." The National Radio Chamber of Commerce, which has set out to end confusion in the radio industry by bringing into harmony all of its instrumentalities, is devising a scheme of practical assistance to educational institutions.
