Telephones on wheels
The mobile telephone center above has been put into service in Chicago. It is designed to assist reporters and officials at special events. The 32-foot bus carries 15 phones—two of them on the outside. It is also provided with 10 mobile radiotelephone channels, several hand-carried radio transmitters, and a powerful public-address system.
TELEPHONE WIRES RUN THROUGH TREE
RATHER than cut down an oak tree which grew directly in the way of a telephone line which was being erected in Wexford County, Michigan, the company cut an opening directly through the tree large enough to permit the wires to pass through without marring the oak. The rectangular opening is large enough so that the branches and leaves do not interfere with the wires, and all that is necessary to keep the opening clear is to trim away the foliage once a year. This opening does away with the necessity of cutting down the tree entirely or of cutting off the top, as is frequently done.
Scientist’s Theory Explodes Hopes of Talking to Mars
THE possibility of transmitting signals to Mars by short waves has long been a moot question among scientists. Some say no, and some say yes, but the latest contribution to the dispute has been made by Dr. Alexanderson, world famous electrical wizard.
Dr. Alexanderson’s stand on the question is negative, for the reason, he claims, that there exists another electrical ceiling beyond the moon which impedes the signals sent out from the earth. He also believes that the signals may get “snarled” in a mysterious electrical medium of some sort, which holds the waves imprisoned for a fraction of a second before releasing them for a return to earth.
PHONE GIRLS USE SKATES
OPERATORS in Los Angeles telephone exchanges go roller skating each night. They don’t have any boy friends along to pick them up when they fall, nor is their skating comprised of fancy turns and difficult tricks. Business is the primary cause of their donning skates.
After 10:30 p.m. phone calls become less frequent, and not many girls are on duty. Distances which used to keep the girls doing kangeroo jumps to plug in a call are now covered with ease.
NEW in SCIENCE
Navy’s Newest Copter is the Kaman HTK-1 eggbeater with two intermeshing rotors. It is easy to fly and exceptionally stable. Photo at upper left shows blower for engine cooling and servo-tab on rotor blade used for control in flight.
Land-Anywhere Plane is a Piper Cub exported to Rome, Italy where Count Giovanni Bonmartini attached his trick landing gear. It is a tank-track type which enables the plane to land on rough terrain. It fits any small plane.
Telephones OF TOMORROW
by J. R. Pierce
Condensed from The Atlantic Monthly
The telephone network is the nervous system of our civilization, carrying messages of demand and direction, of pain and pleasure, to collective enterprises and to individuals alike. The telephone itself is a mere end-organ which enables any of us to make use of billions of dollars worth of complex switching and transmission equipment.
A new car is a complete means of transportation, but a new telephone can be only a small alteration in a massive electronic organism that seems to change with glacial slowness. For this reason it is far easier to see what sort of advances in telephony are technologically possible than to say when they may actually take place, and I doubt if anyone can make detailed predictions concerning the future.
This was the first modem I got for my Apple IIc. I remember being crushed when I tried to log in to a particular bulletin board system and it came back with: “300 baud? Yeah right, come back when you’re at least at 1200.”
“My Apple’s telephone just called up the home office!”
The exciting world of telecomputing. With a Hayes system, you just plug it in! Communicating is so easy with a complete telecomputing system from Hayes. Hayes Smartmodem 300™ is a direct-connect modem for the new Apple IIc. Hayes Micromodem IIe installs easily in an expansion slot in the Apple II, IIe, III and Apple Plus. Packaged with Smartcom I™ companion software, both are complete systems. Best of all, both systems are from Hayes, the established telecomputing leader. Just plug in-and the world is your Apple!
At a current value of $362 I’m pretty sure you could just get a human answering service for considerably less money.
Self-Answering Telephone Thinks and Talks
By Harry Kursh
“HELLO, hello. This is the residence of Mr. John Smith. Your message is being recorded automatically. Ready! Please speak now.”
Don’t be surprised if that’s what you hear one of these days when you dial the familiar number of one of your friends. For Ipsophone—the robot telephone device with a brain—has been placed on the market and is rapidly coming into use all over the world. Three of these ingenious Swiss inventions have already been installed for the King of Egypt but their cost ($38 per month) will make them practical for even the smallest businessman.
Two Ears Now Can Listen at One Telephone
A TELEPHONE attachment which permits the user to listen to a long distance call with both ears, and incidentally allows two people to hear from a single receiver at the same time, has been designed especially for noisy offices. The device is a sound-distributing chamber which slips over the end of the standard telephone receiver and sends part of the sound through a rubber tube ending in a metal cup, similar to that on a doctor’s stethoscope, which fits in the opposite ear of the user.
Wired for Sin – THE VICE RACKET BEHIND THOSE PHONE ANSWERING SERVICES
Bigtown call girls operate freely because slick tele-fronts handle their incoming calls
By JACK MITCHELL
THE TALL, sleeky-dressed blonde got off the hotel elevator and made her way swiftly across the lobby to the telephone booths. Tossing aside a mink stole from her shapely shoulders, she took pencil and notebook from her pocketbook, dialed a number and said softly: “This is June. Any calls?”
