Aviators Fly High Above Clouds, Guided to Their Destination Only by Radio

Recent Tests With Beacons and Small Instruments Enabled Pilots to Keep Planes on Proper Course and Reach Landing Point,

St .4 £ err ice AY TON. Ohio, April 4 High above the cloudd, out of sight of land, yet bound for a definite destination, airplane pilots in the future may thus be guided by radio The promise Is made thrmurh observation of recent tests conducted here with radio beacons and other instruments by which aviators were enabled to fly across country with out a landmark to guide them. Not long ago. Lieut. E. H. Barksdale and Instrument Engineer Brad i<iy_ Jones, flew from McCook Field h“re, direct to Mitchell Field, New York, a distance of 675 miles, in less than four hours and did not see land ihree-fourths of the way? Two Important mechanical instruments figured in this feat. But more recently another flight was made over Dayton high above the clouds, and a system of radio signaling was responsible for the pilot’s guidance. Combination of both methods of airplane guidance above sight of land may be the outcome of further t-sts with both sets of Instruments. On Long Flight The purely mechanical Instruments used in the Dayton-New York flight consisted of an “earth induction compass” and an "Inclinometer.'’ The earth induction compass is a small cylindrical affair with propeller, which is attached to the rear of the plane to remove it from magnetic influence and which controls an Indicator on the instrument board in front. The inclinometer is “the eyes of the airplane,” telling the position of the ship In straight flight, the course it takes in a bank and the fore and aft inclination of the plane. Before he goes up. the filer's course is predetermined, the distance to desti- * ation is carefully figured and the degress necessary to keep the pilot on his course painstakingly calculated. All the pilot has to do is keep the compass needle at zero ard watch the indicator showing the number of miles he has traveled. When the required distance is covered, the e viator noses the ship downward and lands where he had planned." Signal Device The radio beacon is another step in the same direction. By use of this instrument, the aviator receives definite signals by which he can tell whether he is running true to his course. The letters A and T were repeated over and over In the recent test flight. As long as the aviator flew over the correct course both letters were equally loud. But as soon as he swerved ofT, one letter became louder than the other and by this difference he knew which way to turn to get back.

The receiving set he used was of the ordinary airplane variety. The signaling device was developed by the Bureau of Standards in cooperation with the Signal Corps and the Army Air Service. Worked Accurately “We passed through all sorts of clouds and over all kinds of territory,” said Jones in explaining how the instruments operated on his last voyage. “We fleyv 400 miles with never a sight of land. “As our instruments told us we were getting near New York, we watched them closely and by signaling, we both agreed at the proper time that it was time to dive down and take a look. “As the plane nosed downward we began to recognize landmarks and knew that our instruments had been set and that we had read them right. Closer inspection of our surroundings showed us that we had dived down right over Mitchell Field, our ultimate destination.”

RADIO TO PHONOGRAPH New Instrument Combines Both Outfits in Period Model Cabinet. An instrument that combines a radio outfit and a phonograph is the latest innovation in the radio field. The instrument is designed and built like a cabinet-period model phon ograph. The radio set is constructed in one side of the cabinet, while the phonograph is built on the other side along with a loud speaker, which serves for both. By pulling out a lever the switch is made from radio to phonograph. Trade name is the Emerson Phonoradio. It is manufactured by the Wasmuth-Goodrich Company, Peru, Ind.. and is on sale in Indianapolis at the Pettis Dry Goods Company. There are more than 3.000 manufacturers of radio supplies in the United States.

BUILD OF NEW SET SIMPLE Outfits of Future Will Probably Be of Three-Tube Design, By ISRAEL KLEIN Times B..idio Editor T r— HE receiving set of the futcre, say prominent radio engineers, will be a simple three-tube outfit—perhaps single radio and single audio frequency amplification, or just double audio frequency amplification. Therefore, the fan who plans such a receiver for his own use is certain to enjoy an outfit that will last through the various stages of changes and Improvements now being experienced in radio. The ultradyne, the monodyne, the pliodyne and many another “dyne” may come and go, but there can be little doubt about the survival of the simple three-tube receiver. Therefore, for the beginner, a single-tube receiver Is Lie safest bet. Then, if he wants more distant reception and use of a loud speaker, the next logical •step Is a two-stage amplifier. It is hardly worth while adding only one step of amplification, because It would still be ineffective for the application of a loud speaker. Parts Required Hook-up diagram and layout of e typical two-stage audio amplifier are given here. Parts for the amplifier, cabinet alone are: Two audio frequency transformers, low ratio, about 4ts to 1. Two rheostats, 20 ohms each. Two double-circuit Jacks. One single-circuit Jack. Two tube sockets. Five binding posts. One dllectric panel, 7 by 11 Inches. One wood base, 6by 11 Inches. Bus connecting wire. The single-circuit Jack may be the one used with th& single-tube receiver, if that arrangement has been made. Detecttyr Changes Following changes should be made In the detector circuit, for the addition of the amplifier. Double-circuit. Jack should ‘be put In place of the single-jacket Jack, or the two phone connections. The two Inner connections of the I detector Jack should be connected to the primar;/ or the first transformer. One of the outer connections of the retector Jack goes to the plate of the detector tube. The other connection goes to the 22 (4-volt tap of the B battery. Other connections in the detector circuit remain the same.

Other Connections A 45-volt R battery' is required to take care of the amplifier tubes, both amplifier jacks being connected to the 45-volt positive end. The rheostats and negative F of the transformer secondaries are Joined to the negative of the A battery. The second double-circuit Jack Is attached between the first and second stages of amplification. The outside connections Join with the plate of the first amplifier and the positive 45-volt tap of the B battery. The Inside connections go to the P and B—plus binding posts of the second transformer. Transformers must be placed at right angles to each other. TJV2OI-A or C3Ol-A vacuum tubes may be used on this amplifier and a 20-ohm rheostat with each. Tuning 1 la accomplished Just as though there were no amplifier to the detector circuit, except for the adjustment of the amplifier tubes to their highest efficiency by means of the rheostats. This amplifier allows for use of a loud speaker for local broadcasting and DX stations up to 1.000 miles.

Beginner Can Choose Proper Set If 'Commandments' of Radio Are Folloewd. Little things like picking out a wife, selecting an automobile, or buying a new house ara a cinch compared td deciding what kind of a radio set ta build or buy, The multiplicity of types of reeelvr Ing sets available, the extravagant cl?lms made for many of them and the inability of a large section of tbd public to select good sets or parts, make the layman's choice of a set, sk real problem. Ten Commandments Yet no one need to gamble on such an important thing if the following ten points are considered or foil owe t before purchasing a set. They corn stitute sort of a "Ten Comma-nd--ments” of radio. So many articles are written, advertisements published extolling thl 5 * or that circuit that It seems pertl-' nent to give a formula by which. the! merits of each may be judged. The formula consists of ten fnrpew-ta tant characteristics divided by thes costs in dollars and equals satisfaction!/ per dollar. Prime Importance These characteristics are of prime* Importance: Quality of reproduction; volume; range or sensitivity: case tuning; ruggedness; small upkeep expense and low cost. Some cf these characteristics may be rated by one who has never see:* or heard a radio set, while other* need explanation. If they are followed the radio fan. will get the most satisfaction per dollar out of his Investment.
