Dolls Dance to Radio Music
FROM Germany comes the latest radio novelty. It is a platform upon which a group of dolls dance to the tune of music issuing from your radio receiver.
The device is a mystery until you understand the dance platform is caused to vibrate by means of a small needle which connects with a headphone, as illustrated in the accompanying drawing.
This headphone is connected up with your radio receiver, so that the same current sounds the music and excites the dancers. The effect of the contrivance is extremely fascinating.

Radio Speaker Like Chandelier
LOUD speakers which are placed in or on top of your receiving set cabinet are now being supplanted by a new amplifier that hangs from the ceiling like a beautiful metal chandelier.
The new amplifier is made up of a number of tone tubes which not only amplify the sounds but also give musical notes a rich tone. Each tube tones one note. Any electrical connection may be used between receiving set and chandelier.
It’s here at last—relief for your throbbing dialing finger. Just slip this plastic card into Bell Labs’ experimental dialer phone and the number is dialed automatically. The card could also be used to transmit information over telephone lines to computers, or even to check bank balances.

RESEARCH MAKES THE DIFFERENCE
Unlike ordinary Citizens Band transceivers, there are certain distinct advantages in owning the SONY CB-901 fully transistorized unit. One of the most important is the separate speaker and microphone, rather than the combined speaker-microphone found in other sets. This means greater ease in operating and superior clarity in transmission and reception.

By A. J. Steiger
Radio LISTENERS who tracked the earth-circling travels of Sputnik I have reported new discoveries in short-wave propagation, including a round-the-world echo, according to preliminary findings published in a recent issue of Radio, a Russian popular electronics journal.
What the Sputniks discovered about prospects for using solar power to operate space vehicle instruments is also discussed in the Moscow journal. These reports on Russia’s pioneer space vehicles’ discoveries, the first to be published, are translated here.

Call Indicator for Telephone
THE numbers dialed on automatic telephones can now be recorded on a call indicator device invented by William Green-berg of Portland, Ore. In the center of the regular telephone dial is a space where the numbers being dialed are reproduced, showing what number is being called, and warning immediately of any error. Pressing a small button at the top of the device clears the figures for the next call.
Sound-powered telephones make superlative yuletide toys
By HAROLD P. STRAND
SURE THEY WORK—and you don’t even need batteries! What are they? Just a pair of sound-powered telephones that are certain to turn a couple of kids into a pair of happy hooligans for many a fun-time session. And what’s the secret? There really isn’t any— other than the fact that a crystal earphone will work as either an earphone or a microphone, depending on whether you talk or listen.
