Off the “Platter” and into Your Home
WHEN a voice from your radio says: “This is an electrical transcription,” don’t turn to another station, for what you are about to hear is one of the wonders of modern broadcasting. Last year the customers of one of the leading makers of electrical transcriptions for broadcasting purposes paid $30,000,000 for the records and station time.
It is a big business, this offspring of radio. Every broadcasting station in the United States, without exception, uses these “platters.” Many of the smaller stations depend on them for a majority of the time they are on the air each day.
Odd Jobs for Your Phonograph
WHAT will put you to sleep, wake you up, improve your hearing, and teach you card tricks, foreign languages, or duck calls? Simple enoughâ€”your phonograph. New disks make it a jack-of-all-trades to serve your need or fancy. An innovation for curing insomnia is a twelve-inch record, recently placed on the market. Start it going and you will hear a soft, soothing voice telling you how to relax your muscles and free your mind of cares. Selected words and phrases, whose power of suggestion has been proved by experiment, are said to make you drowsy and finally lull you into deep, restful slumber. According to the psychologist who made the recording, a leading broadcasting company considered adopting his idea as a regular bedtime radio feature, but turned it down because of the danger that motorists with car radios would fall asleep at the wheel!
This reminds me of the RCA Selectavision system.
Home Movies From Phonograph Records
PLAY a moving picture from a phonograph record!
When Baird, the English television experimenter, suggested this system several years ago, he did not realize how soon it would be before his prophecy would come true.
Those who have listened to television programs know that the signals become audible in the form of a shrill whistle in the loudspeaker. This whistle carries the picture elements in the form of modulated sound.
Machine Records Voice For Verbal Postal Messages
Sending a verbal postal message to friends instead of a postcard or letter is a new service available to residents of Amsterdam, Holland. A coin-operated machine installed in one of the city’s post offices is fitted with a small microphone into which the customer speaks, limiting the message to about 100 words. Within a few minutes time, the machine ejects a metal phonograph record on which the message has been recorded. The customer then mails the record to a friend who, upon its receipt, can play it on a phonograph.
PHONOGRAPH RECORDS RADIO PROGRAM
You can make a phonographic record of your own voice or record your favorite radio program through an attachment on a new combination radio and phonograph. The attachment does not interfere with the ordinary use of the instrument for playing a record or program.
For record making, a microphone picks up voices and transmits them to a blank record through an electric “pick-up” similar to the reproducing arm of a standard electrified phonograph.
Phonograph Carried as Vanity Case Plays Standard-Size Records
Carried like a vanity case and about the same size, a collapsible phonograph that plays standard records has been invented.
The motor is wound by a detachable crank and the horn opens and closes like a telescope so that it can be folded into small space. The entire instrument weighs but little and is said to reproduce tones as satisfactorily as many larger and more expensive machines.
New Phonograph Record Plays Half Hour Music Program
THE phonograph, long overshadowed by the radio, now promises to come back into popularity, thanks to the development of an improved type of phonograph record recently introduced. Capable of running for a full half hour, the new long-playing record reproduces entire symphonies and vaudeville and musical comedy acts with-out the necessity of changing the discs.
The long-playing feature is obtained by slowing down the turn-table speed 78 to 33 -1/ rpm., and by introducing almost double the number of grooves in the playing surface. The new discs are made from a composition called Vitrolac, which permits placing finer grooves in the record.
The slower turn-table speed for playing the new records is obtained by the use of a special gear shift arrangement, which can be installed in any electric phonograph. The needles are chromium plated.
‘Phonograph’ Tests Mentality
DESIGNED to aid psychologists in determining the mental rating of patients of the crime clinic at the Institute For The Scientific Treatment of Delinquency in London, England, a newly developed machine resembles a portable phonograph in appearance and operation. A waxed record, bearing a series of small red dots, is revolved at varying speeds and the patient is required to jab at the dots with a stylus pen, the number of hits or misses serving to classify the patient’s mentality.
Phono Runs on Spring or AC
One drawback to the production of AC-DC-battery phonograph portables has been the lack of motors that would operate anywhere. Capitol Records, Inc., of Hollywood, combines an AC motor and a spring-drive mechanism with a three-way amplifier to get a truly portable record player.
