Show I Here Is a Simple Way to o Avoid Corroded Contact Beam Wireless Is Scientists Goal Directing Wave in Sharply Defined Beam, Like Search light, Not Likely. By DR. J. DELLINGER ChW of Radio laboratory, Bureau of Etandards. The conspicuous success of broadcasting frequently gives rise to speculation as to the possibilities in other applications of radio. The waves from a radio station have a natural tendency to spread out In all directions. Broadcasting, as we have It today, Is the culmination of development of the nondlrectlonal property of ordinary radio waves. From the early days of radio It has been a goal of scientific Imagination and effort to concentrate a beam of radio waves In one direction like a searchlight. The possibilities of individual communication and of navl- gatlonal aids and control, If such a thing could be done, are. fairly obvious. tfe are so accustomed to think anything possible with radio that we dislike any thought of limitations. Many efforts have been, made to produce radio, beams, and a number of very Interesting things are being done with such directive properties as radio waves do have. Work Thus Far. The directing of radio waves In a very sharply defined beam, like light from a searchlight, Is a consummation not likely to be achieved. Nevertheless the approximations that have been and are being made are of very great value. About ten years ago Marconi demonstrated that by the use of a parabolic reflecting arrangement radio waves could be partially direet-e- d In a desired direction. With such an arrangement the Intensity of the waves along the desired direction was several times that at angles greater than 30 degrees from that direction. With waves of the order of 3 to 10 meters In length a reflecting arrangement of practical size can readily be constructed and the waves can be transmitted distances of several thousand miles. From this beginning, reflecting arrangements of Improved types have been developed by American and other experimenters, giving the evolution of beam system. The beam the system has been adapted for practical use, particularly by Great Britain. Beam stations are carrying regular radio tralflc between England and Canada, and other beam stations are being erected for communication with other parts of the British empire. In these stations wave lengths up to as great as 100 meters are used and the reflecting devices are very large, straight rows of antennas. Instead of relying upon a parabolic arrangement of reflectors the currents In the various wires of the straight row have their phases so adjusted as to reinforce radiation In a particular desired direction and diminish It In other directions. New Short Wave Discoveries. Certain things have been discovered In the realm of high frequencies or short waves in the last year or two which give renewed Interest to the possibility of using beam methods for communication between one point and another. Very short waves exhibit that the phenomenon of Is, beyond a short distance around the transmitting station there may be a zone of several hundred miles where the signal cannot be received and beyond this there will be another zone of a certain width where the signals come In very well. If now It were possible to confine such waves sharply along a given line from the transmitting station, the area where they could be received would be limited in two different directions and thus the signals from the transmitting station would be receivable at Just one limited area on the earths surface. By suitable control of the wave lengths and times of transmission thisa system would permit the putting ofon message down at any desired spot the earth. The trouble Is that beams , cannot be sent out anywhere nearly The sharply enough to accomplish this. dream of radio as a means, of Individual and secret communication between on persons at any two desired places fades away. thus the earth It Is In the realm of navigationalataids that directional radio has tained greatest success. The directional finder is a device now well known to mariners. In its simplest form It Is Indicates merely a coll of wire which the direction from which a radio wave Is coming merely by turning the coll and listening to the variation of the Intensity of the received signal. This simple device has many uses. reBy virtue of Its complete lack of direca from sponse to waves coming tion at right angles to the plane of the coll, it can be used to eliminate Interference from any particular station. As an aid to ocean navigation It is particularly valuable under conditions of fog.

It grated on no ones finer sensibilities to refer to President Andrew Jackson as Old Hickory, a title, albeit an affectionate one, won in sundry battles with the Indians and the British. But Jackson was not the only man whom a military nickname was to carry into the White House. There was William Henry Harrison, who, even though he was the scion of a family of Virginia aristocrats, was better known as Old Tippecanoe than by his real name. There was Zachary Taylor, the Old Rough and Ready of Mexican war fame, and as late as the last quarter century the Rough Rider of the Spanlsh-Amerlca- n war may have helped put Theodore Roosevelt In the Executive mansion as much as did the affectionate Teddy or the historic Initials, T. R. Although he had no military record to commend him to the electorate the man who came out of the Illinois backwoods In 1860 needed none to win for him.

That Is, until one Harold Grange streaked across gridiron history and left behind him the titles of The Galloping or Just Ghost," 'The Red Rover Red." Team nicknames, however, have been popular and more enduring. Who will soon forget the "Four Horsemen of Notre Dame, who rode roughshod over a great Army team to win that title? Or the Praying Colonels of Center college, who sprang Into sporting fame when they bumbled the Virtumighty Crimson of Harvard. ally every college has its nickname, based upon the colors of the school or some animal mascot, but few enjoy the picturesque descriptive names, such as the Golden Tornado" of Georgia Tech, the Green Wave of Tulane or the Thundering Herd" of the University of Southern California. In other sports nicknames are not so common. There are a few which, applied to the outstanding exponents of their arts, have given them national renown. An Indian once saw a girl named Helen Wills play tennis and was so Impressed by the fact that, regardless of how the tide of battle ran, her countenance remained immobile, called her Little Poker Face." Those who have seen Charlie Paddock run recognize the appropriateness of the "Fastest Human," And American runners who saw only the heels of Paavo Nurmi can tell you why be is called Tennis also has the FlylDg Finn. itz Big Bill" and Little Bill" for us the greatest number of national heroes whose nicknames are household words.

The great baseball pitcher may be the hero of the hour, but when his arm loses Its cunning then the crowd soon forgets, unless he has had a popular nickname to fix his personality In the mind of the fan. So Christy Mathewson la almost unique in the history of baseball.
