Experiments with radio communication between moving trains and railroad signal towers had previously been made, but never before so successfully as last week on a mile-long New York Central freight train. In a tower at South Schenectady. N. Y., were Edward W. Rice Jr. and other General Electric officials; on the train were New York Central officials. They talked together, and clearly, as the train moved...
Values of the experiment: (i) Train crews need not signal one another with lanterns, flags or whistle toots; brakemen need not dogtrot over moving car tops to deliver messages to engineers; (2) Train dispatchers can give orders without stopping trains; (3) The voice supplements automatic train signals...
...apparatus is the result of a careful study of the signal strength of radio reception in connection with sun-spot observations. The study revealed that there was a definite correlation between the appearance of spots on the sun's surface and the conditions of radio reception. The new machine, by means of a device that is similar to a weather graph, can measure the amount of change that takes place in the signal strength of radios during the sun-spot cycle...
...must to all men--in the phraseology of "Time"--comes the opera season to the denizens of Greater Boston. It is a signal for many time honored customs: for Willa Jerdone and Betty Alden, experts on Society, to go quite, quite berserk in descriptions of what is being worn in the foyer; for the illustrators of department store advertisements to draw countless long necked and apparently under-nourished grande dames; for H.

...accomplishments of so many who passed under the low lintel of Hollis 15, and in the devotion which these men have always retained for him. They ask nothing better than that the light in the window on the top floor of Hollis Hall, which has been the signal to many generations of Harvard undergraduates that "Copey" is receiving his friends, will burn indefinitely and that even though retired from active service in the University. "Copey" will be "at home" to them until he has lived out the full fourscore years and ten which was the span of life...
