Show ralph H townsend has new invention ralph H townsend more familiarly known in this community as jack townsend sd son of mr and mrs H S townsend of this city la Is in the limp lime light of new york city is as an la inventor and in all probability will yet win tame fame and fortune because of the successful pana trope and thus one by one are our former park city boys making good in various parts ot of america in a column article in the new isea yolk times ot of saturday august 15 1925 the now new invention is described in detail from rom which the following ollof follo Aing ting extracts are taken ken the first demon demonstration demonstrate strat io 0 or the e a new music producing producing instrument developed on principles totally different from those ot of the phonograph was given yesterday at the brunswick Brunsw lck balke collender Collen Col leader dBr briding af at fifth avenue the audience broke into applause tor for the performance ot of the new invention I 1 in hearing bearing a record played on the Pana trope immediately after hearing the records played on a standard phonograph the new instrument which has neither diaphragm nor horn born played disk records produced by an entirely new method the effect was an excellent reproduction 0 of the full orchestra the jazz band the h human union voice the guitar the plan piano I 1 0 the saxophone and other instruments the instrument produced fundamental tones and overtones with much the color ot of the original it 11 II townsend who has been working tor for five years to bring this instrument to perfection said yesterday that laboratory measurements showed that the Pana trope ff reproduced pro 90 per cent of the frequencies or sound waves originally given forth by the orchestra or artist whereas s the standard phonograph at best reproduced 50 per cent of the frequencies quen cies the best phonograph music lie he said has an admixture of andel undesirable sounds caused by the distorting effect ot of the diaphragms an and d horns on tho the sound waves a and ad also by sounds of their own which were interjected acted by tho the diaphragms and her horns for the purpose or of making a smooth transition from the old instrument ment to the new the records which are being issued bear a close outward out iward resemblance to the old ones they are intended ifor for use on phonographs as well as on Pana tropes similarly the old records can be used on the Pana trope with an effect act said to be 10 g bly auve flur ro their use on the old phonograph ultimately the inventor said that I 1 the film record would undoubtedly I 1 displace the disk ile he said that film records had been produced which would run for an hour without interruption ter and that those these would gradually be introduced later the Pant trope Is adapted to play either the film record or the disk record the film record is a film on which the sound round waves are photographed it is la unwound in the face ot of a small but intense light which reproduces the variations ot of the sound I waves ivos vos by its variations in brightness these Nar variations lations are reproduced reproduce dl electrically by means or a photoelectric photo electric cell and then stepped up to the required power by vacuum tubes eventually the power vibrates bratos vi a disk producing the sound waves the apparatus par atus required tor for playing the photographic film records Is very simple and Is planned tor for adjust nickit in the sanie same cabinet which plays the disks the loudness or volume ot of the music Is 13 determined by the number ot of vacuum tubes used this can bo be var ledi 14 by moving a small lever from the volume required tor for a small room to that needed tor a 1 largo large auditorium the inventor said yesterday that while the film records can run an hour leour or longer tile the disk records cannot at present be made to run satisfactorily facto rily tor for more ihan ten minutes ithe the records now being issued are ive five minute re records corda ten minute records will be issued later expert ment luent is golna on tor for the purpose ot of li making laking possible still longer records liy fly the grooves cut in the disks |
