. RADIO TUBE “Electro-Mechanical | ing Outfit Now PRODUCTION Brains” of Receiv- in Daily Use to Extent of Three Millions. BY PAUL GRIGGS. 1 Radio lamps or “tubes” now glow | faintly each night in more than a mil- lion American homes. In some cases ouly a single tube is employed to function as a rectifier of alternating electric current or detector ©f radio waves. As such, the tube constitutes the “electro-mechanical brains,” 5o to speak, af recelving outfits as they pick | out of the alr the equivalents of the product of the human brain and faith- | fully reproduce them in thelr natural form, In other cases additional tubes are employed to assist the detector tube either by amplifying the strength of in- coming rudio frequency oscillations be- | fore they reach the detector tube or | anplifying the strength of radio fre- quenc. lations after they leave the detector tube, or both. i Tube sets emplo; g from one to as many as possibly eight individual tubes are used in present practice, but assum- ing that in the average set only three tubes are employed, one as a detector #nd two as audio frequency amplifiers, We have not less than threc million Rubes in daily use, and the number is constantly increasing. Although the radio tube closely re- Sembles the ordinary electric light bulb in its general appearance, yet their manufacture in quantities and their test involves fur more difficulties and re- guires more skillful _craftsmanship, These features, along with the patent rights, determine the relatively higher individual cost of the radio tube as com- pared with the ordinary electric lamp or bulb. Life of Receiving Tube. Tho operating life of a radio receiving tube is dependent principally on the life of the filament or negative electrode. The filament in turn is dependent on the material used in its construction, the extent of evacuation of air from the bulb and the degree of elimination of the Inherent gases in the filament, grid and plate material, and also in the glass | of the bulb. The presence of harmful amounts of £as in the bulb or even secreted in the material of the tube elements will cause 8 tube to function erratically under certain operating conditions. In fact, the Presence of gas in the bulb is the prin- | use of tubes becoming defective inoperative, even though the fllament itself Is not defective and cur- | Tent may be circulated through the fila- ment eircuit in the usual manner, Of the great army gf radio fans who daily utllize the radio fube probably very few | appreciate the remarkable = processes | through which their tubes have been put In the making. With the assembly into a complete unit of the glass bulb and tube base ! contalning th- fllament, grid and' plate, and thelr connecting terminals, the bulb may be exhausted of air by | the use of a vacuum pump to draw | the alr out through apertures in the| base. With the proper Yacuum obtained, the apertures may be sealed and the space withln the tube left virtually devoid of air. Solution Comparatively Simple. ‘The problem of evacuating the tube ©f air may thus be solved in a com- paratively simple manner, but there is also the very much more difficult problem of eliminating the inherent | gasses in the filament, grid, plate and | the glass walls of the bulb, and evac- | uating these gasses also, gasses extent of | I which must be eliminated for the effectual protection of the tube and ity satisfactory operation. The harmful gasses can be elim- inated sufficiently from the filament during the process of evaculation by stmply circulating a heating current through it of greater value than that used in the normal operation of the tube for radlo purposes. This method cannot be employed in connection with the grid and plate however, because they do not of themselves form closed electrical cir- cuits a§ does the filament, and there- fore ordinary heating currents cannot be circulated through them. Likewise the glass of the bulb, not being an elec. trical conductor, {t is obvious tha clectrica currents cannot be circu- lated through it for heating purposes. The methods employed utilizes fur- nace heat for the glass bulb, electric current for the filament and “electron bombardment” for the grid and plate. The tube is placed in a heating fur. nace, which is then brought to a tem- perature just below the collapsing or melting point of giass. The intense heat drives the harmful gasses out of the glass and into the surrounding space and also into the space within the bulb itself. Meanwhile an electric current of heating value much higher than that normally used in the operation of the tube for radio purposes is circulated through the filament circuit, thereby bringing the filament to a tempera- ture sufficiently high to drive out the < and at the same time bnormally large stream harmful ga: give off an of “electrol These electrons are drawn through the grid to the plate under the in- fluence of a potentlal difference be- tween filament and plate such as to maintain the plate highly positive with respect to the filament, “Electron Bombardment.” Under these conditions, the invls- tble electrons strike or collide against the grid and also the plate with such force and in such numbers as to bring these two electrodes to a red heat, thereby driving the harmful gasses out of thesa elements and into the space within the bulb. The latter named action is commonly referred to as “electron bombardment” of the grid and plate. Simultaneous with these various actions, a vacuum pump operates on the tube, drawing out both air and the released gasses from the space within the bulb, thereby creating a | vacuum within ‘the bulb sufficiently high for all purposes for which the tube is designed ‘With the completion of these pro- cesses, each individual tube Is tested for its filament voltage and amperage rating, the resultant current flow in the grid circuit and the plate circu :d for any evidences of possible pai al loss of vacuum or the presence of harmful gasses remaining in the tube. The present extensive manufa of vacuum tubes involves the ser of glass blowers for the production of the fragile bulb, the mechanic for the manufacture of the filament, grid, plate and base and their assembly, d the radio techniclan for the final assembly of the tube and its prepara- tion for radio work and thelr testing for defects or otherwise when the product is finally completed. The miniature radio recelving tube, which survives the process of manu- facture, assembly, evacuation of air and gas, and its final test, is a most delicate and sensitive electrical de- vice, & work of art in electro- mechanical craftsmanship.

RADIO GOSSIP AND NEWS First actual steps to reduce inter- ference will be taken on May 15 by the Department of Commerce when! 1t assigns about thirty-five exclusive| wave lengths to some thirty locali- | ties where high-powered class B broadeasting stations are situated. | It also Is planned to reallocate at this | time the wave lengths for class A stations. Secretary of Commerce Hoover, it Is understood, already has approved the tentative reallocation of speclfic wave lengths to broadcasting stations, but each district radlo inspector must mow confer with the local operators and owners before the wave lengths are definitely fixed. The distribution of the new wave Jengths, which are based on the rec- ommendations of the second national radio conference. will not be made public until the district radio inspec- tors complete their conferences with the operators. Virtually every class B station will have a national exclusive wave length between 300 and 345 or 375 and §45 meters, except where there are two or more such stations in a To- cality. The waves will be assigned to localitles rather than stations and will have to be shared in some citles, 1t is pointed out. Those wave lengths allocated on the Atlantic coast will be repeated in Pacific coast cities. The difference in time of three hours also will tend to eliminate any inter- ferences. ‘Where two or more statlons exist & time schedule will be arranged. A few wave lengths in each district have been reserved because of an- ticiated interference with other lines of communication or held for new {is | undoubtedly lghtning?* This ds a popular question of this season of the yvear. The danger from lightning may be reduced to a minimum providing proper safeguards are adopted. There is no more danger from the antenna being struck by lightning than there from the telephone or electric light wires running into the house. An antenna properly grounded serves as a lightning rod, gradually letting the statlc charges leak away to the ground before they have a chance to gather and attract an opposite charge from the clouds. It is estimated that a radio antenna not only protects the house with which it is connected, but the surrounding area equal to the size of a city block. Every owner of a radlo antenna should have a feeling of safety during an clectric storm. To Broadcast President's Vofee. The voice of President Harding will vibrate through the ether from either WEAF, the Ameri- can Telephone and Telegraph station, or from WJZ, the Radio corporation, Westinghouse station at Newark, when he speaks before the Volunteers of America In New York May 10. Definite arrangements have not been made relative to the hall in which the address will be given, but it is expected the microphone will pick up the President’s voice from eit the Metropolitan Opera House or t Hippodrome, Such_broadcasting will give Presi- dent Harding the distinction of ad- dressing the largest audience of amy President in the history of the United States. The waves of WEAF and WJZ have sufficient power to carry their message to every state in the Unlon, 50 which ever station places its microphone before the President, his voice will be heard in thousands of homes.

The grid condenser in the WD-11 circuit should be about .00025 mfd and the grid leak two megohms. | This type of tube is exhausted to extremely high vacuum, and there- | fore is not dependent upon inclosed gas for detecting properties. For| this reason tho tube is not critical in | filament current or plate voltage ad- justments. When used as an ampli- fier the WD-11 will withstand a plate voltage ranging from 45 to S5 volts. A plate voitage upward to 200 volt may be used without damage to th tube.

The glow does not interfere with the operation of the tube, as is the case if the tube be “soft.” This blue glow is thought to be caused by phosphorescence given off by salts used to coat the filament The WD-11 can be used frequency _amplifiers and i circults, When more than one is used an additional 1!-volt dr. should be employed with each addi- tional tube. Connect the batterles in parallel. The average life of a dry batterw used with a WD-11 Is from | sixty to ninety hours. A’ new tube, WD-12, is simllar to the WD-11, except that it has a! standard base of the same type and | dimensions as the six-volt tub which fit in the standard socket. The electrical characteristics of the WD- | 11_and the WD-12 are the same. The WD-11 tube has been much in demand by those who want to converj the Army sets Tor long distance re- | ception and those who want to bulld their own sets, because they can be operated by a dry cell instead of the more expensive storage battery. Thi type of tube has been very scar. and many rumors have circulated to explain the insufficient supply. rumor was to the effect that the man- ufacturer wished to sell more of the complete sets in which WD-12 bulbs another, that the corpora- hed to sell thousands of storage batteries they have In stock, and still another that they wished to give dealers time to sell the UV- 200 detector tubes, which require a storage battery for operation, before placing more WD-11's on the market Washington dealers, however, recent- ly received large shipments of the once scarce tubes. Officials of the manufacturing com- puny denied these reports, pointing out that the production of the tubes has reached 5,000 a day, and plans are being made to turn out 10,000 a day to mee: the demand. Work Moving on Station. Work 1s progressing rapidly on the Radlo Corporation of America’s Wash- irgton broadcasting station, which is be'~g installed in the Riggs Bank bullding, on the northwest corner of 14th street and Park road. It is now expected that the station will be in operation about May 15. Virtually all the transmitting and receiving apparatus is in the station's headquarters on the second floor of the building and it will be Installed as soon as conduits for the wiring are placed. More than 2,000 feet of | conduits for wires already have been placed by the E. R. Seal Electrical Company of this city, which has the as radio reflex i request contract for thls work. Workmen also are giving the broadcasting studio an acoustic treatment. Although officials of the radio cor- poration have not made public the details concerning the station, it is said that it will be among the most powerful in the United States and that its signals will be heard in the Hawailan Islands under favorable conditions. The estimated cost of the operation of the station is $160,000 a year. Barrel Organ Discarded. New York “organ grinders” have discarded the famillar “barrel organ” and are using instead push carts on which are mounted radio receiving sets using a loop aerial.

A scene in a broadcasting studio wwill be enacted before members of the National Radio Listeners-In As- sociation at a meeting tomorrow night at 8 o'clock at 1100 M street northwest by the Blossom Inn Or- chestra and a jazs band. R. W. Ennes, corresponding secre- tary of the association, said last| night “there seems to be quite a good ! many people in Washington who wunt to ‘go behind the scenes’ of the Jocal broadcasting stations and see what takes place while a station is transmitting. Of course this could not_be done very well, as a radio studio has to be Kept very quiet dur- ing a transmission; the more co! fusion in the studio the more -con- fusion you hear in your set.
