A-12 SELEMENT TUBE 10 CUT RADIO cOGT “Twin Screen Grid” An- nounced as Promising Dou- ble Efficiency. Br the Associated Press. NEW YORK, January 23.—A new radio tube, hailed as forecasting a re- duction in receiver cost by cutting down at least one-half the number of tubes required, was announced yesterday. It is the “twin screen grid” pentode, or five-element tube, for house current Teceivers, having more than double the efficiency of the four-element "A. C. screen grid tube to which the public ‘was introduced a year or 50 ago. Engineers sald that the tube, a de- velopment of the Ceco laboratories at Providence, R. I, would make possible the designing of a three or four tube receiver that would be equivalent in output to some present-day sets con- taining up to eight tubes. Great Advance Seen. “The pentode,” Ernest Kauer, presi- dent, summed up, “will represent as great an advance in radio as did the three-element tube back in 1906. “The public has been asking for re- ceiving sets which do not employ 50 many tubes, This development makes | it possible to build sets which will sat- isfy that demand. Bringing more sim- plicity into radio manufacture and re- ceiver operation and maintenance. it will reduce manufacturing costs, ma- terial costs and, therefore, costs to the radio public. It means fewer tubes per family, but a great many more families can own receivers, due to the reduced eost.” The tube resembles the screen grid, except that there is an extra connec- tion at the side of the base for the second screen grid, making a total of seven. The base has five prongs, with another connection at the top of the glass bulb. Like the screen grid, it con- tains & screen for the plate, with the second screen between the regular or control grid and the cathode or elec- tron emitter. Much Greater Amplification. Greatly increased amplification is ob- tained through the insertion of the second screen, which lowers the plate impedance, one of the determining fa tors in the efficiency of a tube. Co with the plate impedance of c.| | ’I:HE EVENING 224, which is 400,000 ohms, it is rated at 250,000 ohms. This factor alone, the engineers said, made possible closer matching of the tube's external imped- ance, such as tuning colls, with at- | tendant increased voltage amplification. To determine the efficiency of the tube, its designers contructed a test set containing one of these tubes as a radio frequency amplifier, a power detector and a power output tube. The result | was very satisfying, they said. In an- | other test they replaced the two screen {erid tubes in an ordinary receiver with | the pentodes and got amplification four |times greater than was possible with screen grids. The pentode. they said. may be used either as a radio frequency amplifier or as a detector. While point- ing out that the idea of a five-element tube is not new, engineers said, its prac- tical application has not been attempt- ed heretofore in America. FOR LEAN MEAT DEMAND Institute of Packers Say Fat Is Crowded Out of Modern Dwellings. By the Associated Press. CHICAGO, January 23.—The apart- ment house, blamed for everything from increase in' divorces to the rise of the delicatessen, was presented with an- other indictment last night. Because of apartments, Homer Davison of the Institute of Meat Packing told the Na- tional Live Stock Producers’ Association here, the public wants lean meat. There is no room for fat or for keeping left- overs to be made into hash or soup, he explained. This reacts most on swine raisers, he said, because swine are fed on corn, which makes fat, and they can't be fed on something that makes lean meat, because they are raised mostly in the corn belt and corn is the cheapest, most convenient food. Cattle and 'sheep raisers have solved their problem, he said, by sending lambs and calves to the slaughter house. The only solution is to breed a type of hog that can eat corn and still be lean, he said. Bees’ Drunk Ties Up Line, Trafic_on the rallway linc passing through Karlovac, Serbia, was tied up recently by a huge swarm of bees on a honey drunk. Derailment of a freight car caused a broken honey jar to release its contents on the ground. Bees tracted by the sweet made the air blacker than during a thunderstorm and forced the wrecking crew to flee. Not until 12 hours later, when all the sweet had been consumed, could the men re- sume their work of putting the car back on the tracks. { | | | about 83 in cash, an automobile oper- | PURSE-SNATCHERS ATTACK TWO WOMEN‘ One Escapes With Pocketbook of Miss Lydia A.

By the Associated Press. GREENWOOD, Ark., January 23.— Greenwood’s new “no whipping” high school, built from a bequest by a foe of corporal punishment, was in ruins yes- terday, after a fire of undetermined origin. ‘The one-story brick structure was dedicated with impressive ceremonies last Armistice day, which was designated as “Alexander Day,” in honor of the late E. S. Alexander of Dallas, Tex., who bequeathed $30,000 for its construction. Alexander was a merchant in Green- wood and a member of the school board for 30 years. As such he bitterly opposed corporal punishment in schools.

Dead Peer’s Diary Is Ordered Sealed For Half Century Viscount Esher, Power Behind British Throne, Was Kitchener’s Aide. By the Associated Press. LONDON, January 23.—Viscount Esher, 77, who was for many years one of the most noted and influential of British peers, died suddenly yesterday. He left a war diary in the custody of t' . British Museum to be kept sealed until 1981. Since the viscount was closely associated with royalty and was | the representative in France of Lord Kitchener when the latter ruled the war office, his diary one day is expected to furnish most “important historical matter. The successor to the title is the Honorable Oliver Sylvain Baliol Brett,| who married Antoinette Heckscher of New York, who thus becomes Viscountess Esher. The late viscount was a close per- sonal friend of King Edward and King George, so close that he was sometimes called “the power behind the throne.” PIONEER LUMBERMAN IS DEAD IN ONTARIO Adam W.

O lubricate, an oil must decrease friction between metal surfaces. A motor oil does this by separating the metal surfaces, and theoretically keep- ing them separated under all operating conditions. It may amaze you to know that many oils frequently fail to do this. ' Think how this “separation” of mov- ing parts is accomplished. The oil forms a wall or “film” between opposing sur- faces ...and it is upon this film that the reputation of every oil must rest. The film is thin, of course, for it must ride in the tight crevices of bearings, cylinder- walls; etc. . . . But it must also be of ex- oils were “oilier” than m ineral oils could ever be, but were impractical for use in internal combustion motors which operated at high temperatures. Finally the Germ-Essence, contain- ing the “oily” property lacking in min- eral oils, was isolated. And a method was devised for combining this essence with highly refined mineral oils. Only Conoco Oils Are Germ- Processed . . This Gives Them Penetrative Lubricity Continental Oil Company now owns convenient to our many patrons and one that affords proper display of our goods. the exclusive right to Germ-Processing for North America.
