RADIO FADING M NOT CAUSED BY VOLTVARIATION Breaking Tube Filaments Usually Are to Blame For Trouble. BY JOHN T. HAWKINS Time. Radio Editor Many complaints have been received by this department lately regarding excessive fading cm radio sets at night The theory has been advanced that voltage variations on the Indianapolis Power and Light Company circuits are responsible. This is true in some localities of the city, where at times the voltage falls so low as to fail to light an ordinary light bulb to normal brilliance. but is not responsible for the greater amount of program fading. Two Routes Used As far as is known in radio engineering, radio waves are propagated or transmitted by two distinct routes. The first Is the ground wave, the signal that follows the ground and which is extremely limited in range. The other is the ether route, making use of that intangible quantity in space called ether. Transmission in this medium, according to present beliefs, is dependent on the Heaviside layer, a strata of complex composition In the upper atmosphere. This Heaviside layer is supposed to act as a great reflecting mirror for radio waves in the same manner as an ordinary mirror is to sunlight. The whole theory of fading in radio receivers is based on the reflecting properties of this layer in the upper atmosphere. It can be seen readily that if the Heaviside layer is in such position as to be reflecting a radio signal at a certain spot, the signal will vary in strength as the layer moves up or down. In other words, your antenna will be out of focus, if the term may be used, as the radio signal Is reflected back and forth by the movement of the Heaviside layer. Layer More Pronounced At certain seasons of the year and during changing weather conditions, this layer seems to be more pronounced in its movement and at the present time, it seems to have reached a peak in its activity This explanation of fading does not take into account, however, those individual cases where defective heater type a. c. tubes are being used in the radio set. ' Laboratories of the Radio Corporation of America during the last six months have brought out five different designs in the familiar UX 227 heater type vacuum tube. Ihe reason for this Is breaking of the Aliment in use due to strains imposed on it. The tubes apparently will be functioning all right and then the filament will go out. The elements in the tube will cool slightly and the tube again will fight, repeating this cycle of operation as long as the set Is turned on. The broadcast listener notices only one thing however, the program keeps coming In and dying out The action of the tube in this case is due to the filament expanding and breaking Its connection and the coding and making the connection again

SODA FOUNTAINS GET $700,000,000 YEARLY Statistics Show Decline of Heavy Lunches Among Men and Women. Bj i'imcs Suecial NEW YORK, Dec. 4.—Americans spend $700,000,000 annually at the soda fountains. Approximately $250,000,000 more is spent each year at these counters for sandwiches and luncheons, representing a little more than 2 per cent of this country’s retail trade. These figures have just been made ’- ’blic by William J. Baxter, director of the chain store research bureau of New York City. New York City consumers alone eat approximately 2,000,000 sandwiches a day the report continues. The chain stores now report from 50 to 60 per cent of fountain sales in luncheon items. People don’t eat as they did ten or fifteen years ago, especially at noon , this research bureau concludes. The sandwich and salad are fast replacing the steak and pudding. The number of men eating a heavy noon meal has decreased. The number of women eating their noon meal outside the home has greatyy increased, due to their employment in industry.
