NAB reports (Mar-Dec 1933)

lating to broadcasting apparatus has not been tested in court. There are many patents on crystal oscillator circuits, devices and methods of manufacture and many conflicting claims. It is of interest to note that most of the Wired Radio patents listed are the results of work Conducted by government employees in government estab¬ lishments, principally the Naval Research Laboratory. The legality of such procedure whereby private corporations may secure rights to inventions made by government employees has been upheld by the Supreme Court of the United States in the recently decided Lowell and Dunmore case. The National Association of Broadcasters is informed that nego¬ tiations are under way for licensing the Western Electric and the Westinghouse Electric and Manufacturing Company under Wired Radio patents pertaining to broadcasting apparatus. It is suggested that owners of composite radio transmitters or apparatus or equipment of other than RCA, General Radio or Western Electric manufacture consult the National Association of Broadcasters if faced with suit for infringement, furnishing exact allegations in the suit. Wired Radio Patents of Possible Application to Broadcast Trans¬ mitters: 1,608,047 — Radio signalling apparatus — 4 claims covering use of concentric transmission line between transmitter and antenna. The circuits are unconventional, however, in the methods of terminating the line. 1,619,854 — Piezo-Electric Crystal Apparatus — 5 claims relative to crystal holder, comprising a retaining ring around the crystal having a plurality of inwardly directed contact¬ ing portions to prevent the crystal from wandering around in the holder. 1,800,576 — Piezo-Electric Crystal Apparatus — 6 claims relative to crystal holder of the air-gap type having an element to keep the crystal from moving vertically. 1,831,151 — Temperature Control System for Frequency Determin¬ ing Elements — 6 claims relative to temperature control box having a fan to circulate the air inside the box. 1,848,630 — Piezo-Electric Crystal — 5 claims relative to a quartz crystal having the electrodes cathodically deposited on the surfaces of the crystal. 1,822,825 — Piezo-Electric Crystal Apparatus — 3 claims relative to means of changing air-gap or pressure of crystal holder by screw-thread adjustment. 1,830,642 — Piezo-Electric Controlled Oscillating System — 13 claims relative to use of 4-electrode tube in a crystal oscillator circuit. 1,688,714 — Piezo-Electric Crystal Apparatus — 5 claims relative to adjustment of air-gap in crystal holder. 1,683,093 — Piezo-Electric Crystal Apparatus — 4 claims on screwthread adjustment of electrode spacing in crystal holder. 1,572,773 — Piezo-Electric Crystal Apparatus — 16 claims on crystal holder, covering hermetic sealing and electrode arrange¬ ments. 1,896,238 — Frequency Control System — 3 claims relating to use of untuned crystal oscillator circuit with an inductance in the plate circuit. 1,822,928 — Piezo -Electric Plate — 9 claims relating to method of manufacture of circular quartz disks. 1,738,041 — Piezo-Electric Crystal Oscillator — 3 claims relating to crystal oscillator circuit, of the tuned-plate variety, hav¬ ing a parallel plate supply through a choke coil. 1,724,232 — Piezo-Electric Crystal — 6 claims relating to rectangular crystals in which the axes are proportioned to each other in a ratio which is equal to a whole number. 1,696,626 — Control Circuit for Electron Tubes — 3 claims on crystal oscillator circuit having a choke coil in series with the bias voltage supply, and a parallel plate supply with a choke coil in series with the “B” voltage supply. 1,683,091 — Piezo-Electric Crystal Holder — 14 claims on pressure type of crystal holder, whereby pressure is exerted by a resilient element between case and electrode, and on multiple crystal holders. OIL CODE REGULATES ADVERTISING The code of fair competition submitted to the administrator of the National Industrial Recovery Act by the petroleum industry on July 13 contains several important rules governing the adver¬ tising of petroleum and petroleum products. The code has not yet been approved by the President. The rules relating to advertising are as follows: “Lotteries, prizes, wheels of fortune, or other games of chance shall not be used in connection with the sale of petroleum products. “Refiners, distributors, jobbers, wholesalers, retailers, and others engaged in the sale of petroleum products shall not give away oil, premiums, trading stamps, free goods, or other things of value, or grant any special inducement in connection with the sale of petro¬ leum products. “The broadcasting or publishing, in any manner, of a claim, representation, or implication which might be reasonably construed to lead to a false or incorrect conclusion in regard to the goods, prices, or services of the advertiser, or in regard to the goods, prices, or service to a competitor, or which lays claim to a policy or con¬ tinuing practice of generally underselling competitors, is an unfair and uneconomic practice and is prohibited.” SECURITIES ACT REGULATIONS Copies of the Federal Trade Commission’s regulations under the Securities Act will be ready for distribution early next week. These copies will be punched for the NAB HANDBOOK and members are urged to include them in the handbook along with the copies of the act previously sent. As pointed out in earlier issues of NAB Reports, the regulations relate in part to the advertising by radio of securities issues. MEMBERSHIP DRIVE TO BEGIN The Managing Director sent to the printer this week a compre¬ hensive outline of all activities of the NAB which is to be used in connection with a membership drive to be conducted under the auspices of the Membership Committee. Every member of this Committee and every member of the Association is urged to assist in this drive for new NAB members.
