EXPERT ADV No. 37—To Make a ICE ON RADIO Simple Vario Coupler. W BY A. HYATT VERRJLL Expert on Radio Technology. n many ways a vario ooupler is a more efficlent and satisfactory form of loose-coupled inductance tham the ordinary loose-coupled coil and it is even simpler and easier to con- struct. 3 To construct -the varlo coupler shown In the accompanying draw- ing you will require a stator or outer tube about four and one-half inches in diameter, five to five and one-half inches in length: an inner or rotor tube of the right diameter and length to revolve freely within the other without touching any- where, after allowing space for the wire winding: a sheet of bakelite, a brass rod a quarter-inch in diameter and_about six inches long, a knob, - six binding posts, a six-point switch, a plece of wood for a base and the necessary wire. Winding Outer Tube. Commence winding the outer tube by threading one ead of the No. 26 ‘wire througn a hole about a half-inch from the tube end, as shown in the cut, and wind on the wire, keeping the turns close together but not touching, and take three taps at about every ten turns, beginning with Wind on thirty- the second turn. #ix to forty tumm: with a drop of sealing it across diagonally, leaving a bar space a half-inch wide on the tube and %o on winding for thirty turns more. taking three more taps as illustr: in the figure at A. Finish by run ning the wire through another hol a half-inch from the end of the tube and fasten with sealing wax, leavini about eight inches of loose wire frex To Wind Roto. wax, b Winding thg inner coil or roto is simpler because no taps are taken No. 20 wire.

LONDON, June 20.—British govern- ment officials are giving close study to American methods of wireless broadeasting and _ gradually are adopting some of them. While tt wireless telephone is not as popu in England as in the United Stat due largely to government lic and control, people are beginning to show intense interest fn it. S of the big London have established wirele and are selling receiving sets for low as $10. Crowds of entertained each day concerts, spesches and weather re- ports. Direct contact with Arling- ton and other American stations is easily established. Nothing written on the subject of wireleas broadcasting has brought it home to England so vividly as a re- cent New York dispatch to the Lon- don Times. “In the United States.” says the correspondent, “there are already Iglf a million home-made re- celving sets for listening in and a million manufactured scts have been s0ld.” In answer to a published state- ment that wireless broadcasting -of | concerts would hurt the musical and theatrical industries, Louis Sterling, president of a larze American phono- graph company, has said that in th march of science thers never yet wi a _great invention that had not been | of "incalculable benefit both to the industry with which it was imme- diately concerned and to kindred in- dustries. “When grafophones were Invent- said Mr. Sterling, “people said they would kill pianos; the cinema was fully expected to give the quietus to the legitimate stage: vaudeville was at first looked upon as the death dance of musical comedy. None of these things has happened. The new has in every case benefited the old.” S TEST OF RECEIVING SET. Loud Speaking Outfit Successfully Demonstrated at Bowie. A loud-speaking recelving set, proj erty of James W. Cook of the Radie Institute, was demonstrated suce fully recently from the balcony uers rothers, eneral st Bowie, Md. . ¥ Pittaburgh and the Naval Air Sta- tlon came in very clearly h their proadcast, and Naval Air Station in gach volume that the concert could ve heard for a distance of two squares. Commander Hibino of the Toyal Japanese navy. assistant naval attache of the Japanese embassy, was with the demonstrating party, for the purpose of obtaining data for a re- port to his government on “The Mani- fest Interest and Success of Radio In America.” Because of the special in- terest and success in outdoor con- certs, Mr. Cook contemplates a repeti- tion of this demonstration with special equipment, in an effort to cover larger areas by increasing in volume the penetration of the re- celvers. of at nsurance ‘Advisers We are something more than mere agents—solici- tors of insurance business.

Bore the proper holes in the bake- lite pancl, as shown in figure D, plac- ink a quarter-inch hole for the rotor shaft two inches from one end and three and one-quarter inches from one side. Make the six holes for the switch contacts and the hole for the switch-arm post in one corner. Make six holes for hinding posts nlong one cdge and bore holes near another edge for screws to secure the panel to the wooden base. The rotor should be slipped inside the outer tube, the rod passed through the “holes in both and through the hole in the panel and the outer tube, secured to the back of the panel hy small screws throngh bare ends of the tube. Th secure the rotor to the rod by sealing wax or glue on the inside of the tube and secure the shaft so it cannot move 'k or forth through the panel and outer tube. This may be done by washers and nuts, or washers and I pins, or even by washers fas- 1 to the shaft by means of seal- ing wax. One or two fiber washers may be inserted hetween the outer and inner tubes on the shaft, if you prefer (Figue E). Finally, fasten the ‘knob or handle to the projecting end iz of the shaft and lead the wires to their proper terminals. Vario Coupler Used.

IT's A DANDY! EVERYTHING SHUTS UP BRAZIL ENDS MONOPOLY. | American Telegraph Firms Admit- ted to Eastern Coast. Action. of the Brazillan government admitting American telegraph compa- nies to the east coast of Brazil, formerly held as a monopoly by the British-owned Western Telegraph Company, is said to remove the chief objection raised by the United States government to the ad- mittance of that company to the United States over the proposed Miami-Barba- dos cable of the Western Union Tele- graph Company. Efforts to install the terminal of this cable first brought the situation to public view in December, 1920, when several destroyers dropped anchor in the Florida port and forcibly prevented operations of the cable ship. The Western Union took its fight to the courts and a suit was pending in the United States Supreme Court when announcement was made that a settle- ment had been effected on the basis of the Western Telegraph Company aban- doning its monopoly in Brazil in return for equal concessions from the All- America Cable Company in connection with landings on the west coast.
