Radio Broadcast (May 1929-Apr 1930)

"A penny saved is a penny earned" is not true in purchasing instruments for radio servicing work. The small difference in cost between the best obtainable meters and those of secondary value comes back to you many times over in the money you can make and the business reputation you acquire through the use of reliable equipment. Shown herewith are two designs of miniature panel instruments — 2" and 3J" diameter — for use in the repair shop and in portable testing work. These are the instruments selected by Commander Byrd for his Polar expeditions. Preferred for their nicety of construction and superior electrical characteristics. Made in A. C, D. C. and Thermocouple Types, and in all the required ranges. Open scales almost to zero position. Designed for flush panel mounting. Write for Circular JJ, containing complete descriptions and prices. INSTRUMENTS WESTON ELECTRICAL INSTRUMENT CORPORATION 604 Frelinghuysen Ave. Newark, New Jersey 236 • {Continued from page 235) corporation was made and this was secured by the option on National Union stock. At this point Senator Hawes of Missouri asked of Senator Dill the reason for this trend of inquiry into the financial activities of the corporation. Senator Dill replied that he had heard stories, that the RCA was endeavoring to "browbeat" companies into effecting license agreements with it on patent infringement grounds but that the facts, as explained by Mr. Sarnoff, "disprove" these reports. In concluding, Mr. Sarnoff said that the 1\ per cent, royalty on receiving sets is levied on the "full completed article," and not on the cabinet or chassis. RCA could have placed a 15 per cent, royalty on the selling price, he said, which represents about one half the cost of the radio set. Senator Couzens observed that the policy adopted by RCA is that it is better to charge a flat rate on the whole rather than a high rate on the chassis alone. This has been found effective in the automotive industry also, he declared. Aerovox Sues Dubilier The Aerovox Wireless Corp. sued Dubilier on patent number 1,736,764 on the use of mineral oil as a cooling agent in the manufacture of condensers. In addition to damages asked on the alleged infringement, a counter suit has been filed against Dubilier for damages totalling $500,000. Sonora Acquires Home Movie Before the involuntary bankruptcy action brought against Sonora Products late in December, it was announced that, the company had in production a home movie unit including motion picture projector, synchronized phonograph, and radio receiver. It was also announced that the company had a compact six and seven-tube radio set for installation in automobiles. DeForest Sues RCA "Under the Clayton Act the DeForest Radio Company is entitled to triple damages for the period in which Clause 9 of the RCA contract with receiver manufacturers was in operation," said James W. Garside, president of DeForest, recently. The DeForest suit for damages, it was said, was not to bring about loss of RCA radio licenses as provided for under the radio act of 1927, but merely to press the suit for damages. Radio Interference Manual A 64-page booklet combining all engineering data secured by the Tobe Deutschmann Corporation on radio interference prevention and a catalog of Tobe apparatus for many special purposes in this connection has just been issued. Copies can be had at 25 cents each postpaid from the company at Canton, Mass. Dayrad — a New Name Radio service equipment manufactured by the Radio Products Company, of Dayton, Ohio, will, in the future, be made under the trade name Dayrad. E. T. Flewelling, formerly associated with the company, has resigned. Dayrad radio service instruments have been developed by an engineering personnel working independently of Mr. Flewelling and additions to the line will be announced shortly. Bosch Dispute Settled Settlement of litigation between American Bosch Magneto and Robert Bosch Magneto has been made. American Bosch secures the sole right to the use of the single word " Bosch" on automotive products, radio and all its other products in the United States, Canada, Mexico, Cuba, and American dependencies. Remote Control Patents As announced recently by E. F. McDonald, Jr., president of Zenith, the following patents are held by his company covering remote tuning and immediate tuning or the combination of both, providing that such tuning is done automatically.
