Theoretically, we have thus been furnished a basis for the conceptio} of the smallest particle that cal} exist in the constitution of matter, us well as the basic unit of electricity The conception of it or the lack cf jts conception by the average per- son obviously is a matter of little or no consequence, but the concep- tion of the electron on which the “electron theory” is hased has been and is of very great importance to sclentists and scientific progress. The promulgation of the electron i thenry and its subsequent Investi- gation and proof has enabled scien- tiats to clearly and logically exp many a_bafMing phenomenon previously was unintelligih ierefore, could not he explained Alko. the electron theory has heen of invaluable assistance to scientists in the development of the modern radio tube, both for reception and transmission, and obviously, there- s, fove, this theory has assumed the status of an tremely valuable commercial asset, Basis of Radle. From the intangibl mind a modern English scientist who promulgated the electron theory there has, for example, grown our radiophone breadcast programs of today. our great tangible army vad and the tangible and ex- tren important industry that has sprung up as a result of the very tercst in radiophone broad- ) fans, casting Individually, the power or strength the electron is thousands of bil- ons of times less than that of a <trand in the web of a spider, for example.

Mcthods Refined. With the obtaining of additional and more complete knowledge along these lines, the Information gained is applied in devising ways und means for making refinements to the exist- ing types of tubes, whether receiving or trunsmitting, Wwith a consequent fmproved performance in thelr opera- tion and a betterment of the useful service they render. As evidence of the rapid progress being made in effecting refinements to the basic tube, we now have the receiving tubes such the type WD-11 for the filament operation of which only an ordinary inexpensive dry cell is required, as compared with the expensive, cumbersome, and troublesome storage battery formerly required. In the dry cell type of re- ceiving tube only one to one-and- one-half volts are required across the flament terminals, as against from five to six volts previously employed. The current consumption In the fila- ment circult is approximately one- fifth ampere. as against one ampere or more previously required. Yet we obtain as from the later type tube as from the older type, due to the fact that the filament material of the later type tube has been coated with a newly discovered oxide from the use of which a relatively greater stream of electrons can be ohtained as a result of the expenditure of much less electrical heating energy Better Tranamitters. In the transmitting type of tube we have progressed withing the past five or six years from the 50-watt tube to tubes two thousand times more powerful. or the 100-kilowatt tubes emploved for ecxperimental radio-telephony across the Atlanti and the prediction is freely made that the practical production of 1000-kilo- watt transmitiing tubes is not far distant The “peanut” recei max he carried in the the same high power transmitting transmission across the Atlantic The essential difference is only in size, the size of its physical elements being dependent on electrons the tube is designed to ac- commodate when functioning. Complications are introduced into the manufacture and operation of transmitting tubes of high power due to the necessity of associating a cir- culating flow of water or other cool- ing process with the plate or positive electrode of the tube in order to off the excess heat dissipated by the plate in the operation of such tube heat which represents energy lost in Taw ing tube which vest pock device as the consequence of the tubes functioning | and which must be carried avoid the partial or total de; of the tube. In such tubes a metal ordinarily employed place of the glass bulb, the metal container us- ually functioning in the dual capac- ity as the plate or positive electrode and also as a receptacle. devoid of air and gas. in which the fllament electrode and the grid electrode are inclosed. In subsequent articles an attempt will be made to describe in non-tech- nical language the functioning of a tube as a detector, as an amplifier. and also as a generator of electrical oscillations for the creation of ether waves for transmitting purposes.

This survey, the first to be made, and now well under way in all parts of the country, “vitally con- cerns every one in the radio industry as well as the entire public,” accord- ing to the announcement of the cham- ber issued after a meeting of the bourd of governors, at which numer- ©.3 groups were represented.

In prosecuting the survey the chamber is gathering information in every section of thé United States. Amonk the questions asked are these: “Have you an ddequate supply of these tubes? “Have you & supply in sight for the next two months? “If the supply of any of these tubes is short, when did such shortage first appea “What number of each would you deem an adequate stock? “What number of each does your trade normally demand for the sea- son?

Every member of the Delivery Corps is aiming for 1009 perfect record—striving to lay your Star before your door at practically the same hour every day.
