BY MIKE MACINTYRE. At an interesting social event the other evening. the entertainment was mostly by radlo—not only did guests|. listen to news, storfes and the gén- eral gossip of the alir, but they danced to the strains of the music broad- casted from a nearby: station. = On every hand conversation about the “good fun” the radlo tele- phone afforded. To most of us who have radio equipment in; our home the radio is but a toy, a means of bringing good music and ‘other forms of entertainment within our four walls. But there is a very serious side to radio telephony as well. Did you ever stop to think what an important part the radio played in the recent war? We, who are so absorbed with the pursuit of broad- casted pleasure, often do not. but an Interesting _story told recently by Capt. C. O. Van Vorst, U. S. A.. brinks home to us the more serious purposes of the great Invention. Like most soldiers, the captain has had enough adventure to fill a book, but he re- lates the following as his most thrill- ing experience: “It was while I was stationed as division radio officer of the 8th Divi- sion In the St. Mihlel sector that a radio message saved the “division headquarters and the entire staff from destruction. i Radio Set In Dumoat. “Our division headquarters was es- tablished in an old church in & town that had been vacated only that morn- ing by the enemy. who had been there for the past four vears; consequently | mfixw New Apparatus and Devices ‘===========By Ralph Brown, Radio Expert RECTIFICATION WITHIN A TWO ELECTRODE TUBE. A vacuum tube with a filament and a plate, but no grid electrode, is called a two electrode tube. It is the father of the three electrode tube that radio experimenters and others know so well, at least by sight. Electrons are given off by a heated filament in this tube, as well as a three electrode tube. and if the plate is positively charged these eléctrons are attracted to the plate. A current of electricity then flows through the. tube and fhe circuit, including the plate and filament terminal to which the circult is connected. But If the plate is given a megative charge the electrons emitted by, the filament are repelled and do: not.reach the plate: There is then no eléétric currémt in the circuit.” 1f the filament terminal and plate are connected in series with a battery across an alternating: current line; the current can then flow in but one direction through tie battery. When the plate is negatiye no current ¢aa | fin flow and current’ only passes when lthe the plate is positive. The alternati: centered | EXPERT ADVICE ON RADIO o. 52.—Life Saved l;y Radio. § it was well fortified, with augouts and bombproof shelters. I had the divi sion radio station established in wha! was left of an old battalion head- guarters’ dugous, under the brow of & hill, facing:a smal créek. “The engmy had bees throwing high @ explosives: over all day, but they did little damage. as our aero squadron had been so active in keeping the German fire control plane away *that the enemy eould not determine. the effectiveness of his fire. Orders hdd been;récdived cov- ering the objective for the.next day. While | was working on some rodio plans the radio. operator remarked, ‘Captain, have You noticed that those shells are coming ¢loser and closer? He asked me to lléten in and see what I could make out'of the German plans, which Rsd"béeen gending the same code letiers over and’ over for the past half hour. 1dld so, and after each shell that exploded I could hear that plane sending ‘XZ8945." It occurred to me that he was directing the big gun, #o I copied the code and hastened to my chief. While 1 was laying my theory before him, the general came out of the hole where he was trying to-get a wink of sleep. He listened to what I was saying, and agregd he believed [ was right. Orders were immediately issued for every man to seek shelter. “Not twenty minutes later a large shell was planted in the middle of the room where the divisfon staff had been quartered. " Later; in:discussing the inci- dent, the general was grateful and pro- fuse in his thanks that radio was with us, for undoubtedly the wireless had that day saved all of our lives.* It is an experiefce like thit which Gapt. Van Vorat relates that makes us realize there is a sprious side to radio. as well as its pleasure-giving pro- | pensities. (Copyright, 1922.) = current is thus rectified and flows in spurts in one direction tbrough the battery. Considering the space between the filament and plats’ with- in the tube, the current can only flow from plate to’ filament, byt not in the opposite direction. When & storage battery is being charged it i necessary to connect the posi- tive battery terminal to the positive side of the line when direct current is used. That is, for charging, the current must flow through the bat- tery from its positive to its negative terminal. It is readily seen, then, that 1f the current through the tube: flows only from plate to filament, the negative terminal of the battary must be ‘connected to the plate of tha tube. The two alternating current line wires may then be connected, one to! the positive terminal of the battery | and the other to a terminal of the tube filament. The filament has, of course, two terminals. If the line is connected to the negative terminal the current from plate to filament flows through one side of the fiament in the same direction that the current flows through the filament from the filament lighting, or “A" battery. This is the connection customariiy made since the main current does not then pass through the filament lighting battery. ADMIRAL MORESBY DEAD.

A VACUUM TUBE RECEIVER REQUIRING NO PMTE BATTERY: - While plate or. as they are pop-. ularly called, * “batteries ordi- narily last a long time in vervice and usually_ give little .trouble, they do occupy §pace.
