NEW YORK (#).—Television may not | used to tune into the picture broad- | b2 just around the corner. but Cort- | casts. Any good set that will receive television signals audibly will give satis- factory results. New Form Amplifier Described. “As transformers are unsuited for am- plifying all frequencies, a resistance- coupled amplifier plays an important part. The audio amplifier of the set is not used. the television intensifier be- ing cut in at the detector output. If the set does not have a detector jack, one must be provided. “The television tube is connected to the output of the last amplifier tube in place of the speaker. This tube is placed at the rear of the scanning disk, which is set on the shaft of a motor, and a small window is mounted in front or in the rear of the disk. The speed of the | disk must be kept in step with that at the transmitter. @peed is regulated by a rheostat, cut into the line feeding the motor. For close adjustment two rheo- stats will be needed. How to Get Best Volume. “Before actually connecting the am- plifier to the receiver it is advisable to tune in to the television signals to get the best volume. Then the audio am- plifier is disconnected and the resist- ance amplifier cut in at the detector jack. The switch controlling the motor is turned on and the disk speeds up slowly, the operator watching for sig- | { nals through the window. As the disk | approaches critical speed, flashes will be { thrown across the window and figures will appear when the correct speed Is i reached. The picture will remain until | again, but by careful adjustment of the | motor rheostat it can be brought back. “The amount of illumination of the television lamp is governed by the out- put consumption of the tube and the strength of the signals. In the resist- ance amplifier two hi-mu tubes are preferable in the first two steps with a power tube in the last step.” AUGL T] 10 8. Scheduled for Eastern standard time.

Radio officials of the United States Navy and the Shipping Board profess to be very much impressed with the performance of a static-reducing device known as the clariphone, the invention of William J. Scott, retired chief elec- trician's mate, U. S. N They testify that experiments with | the clariphone on long wave code cir- | cuits have shown that it suppresses the ‘ frying and the crackling that is the | {bane of all radio. Built on electro- | acoustical principles, it clarifies radio | signals that otherwise could not be | heard on account of a preponderance of static strength in the mysterious | | ether. Only One Made. The only existing model of the inven- tion was installed carly last May in the radio central of the Navy Depart- ment at Washington. Radio men there have attached it to the San Francisco, Balboa and other low frequency cir- cuits employed by naval communica- | tons, which is the nerve center of the overland and flect radio system. Almost | invariably they have reported succes: in its operation, though recentls have had occasion to use it on frequently due to an unusual absence | of static disturbance Spurred on by the encouragement given him in the office of naval com_ munications and elsewhere, the inven- tor has now begun to bufld a clari- phone with a range that wiil embrace | all the tones and frequencies of broad- casting. He believes that he has found and demonstrated the basic principle | that will lead to the entire elimination of static from broadcast as well as code | reception. As described in an official naval com- munication’s report, the _clariphone operates as a sound filter. proof box are a loud speaker unit, sev- eral sections of small brass tubing and a microphone. The tubes are so ar- ranged and of such dimensions that they will permit the passage of sound waves or tones of a particular fre- quency.

Every frequency of the pipe organ and plano will have to be | filtered. Therein lies Scott’s next prob- | lem, but he believes he has solved it and will one day be able to make avail- able a clariphone which will clear any | receiving set of static interferences. Even now, though it has never been tried out on short waves and the me- dium waves used for broadcasting, the inventor maintains that the clariphone can be adjusted to any frequency. He also thinks that it will be invaluable as |an eliminator of scratching and other nolses from phonogral h records, the talking movies and nol | apparatus like motor generators. Has Worked 21 Years.

He served in China and the Philippines part of the time rated as a chief electrician. An fllness led him to take radio lessons at the Brook- Iyn Navy Yard in 1904. One of his in- structors was Jack W. Seanlin, now a retired ‘ chief radioman but still at- tached to - naval communications for the Civil Service Commission. Scanlin was instrumental in getting Scott the assignment as radioman in charge of the station on the Island of Culebra on the Virgin Passage in the West Indies. The isolation of that assignment instrument-building ideas.
