FRAME SUCCEEDS GILMORE AT WESTERN ELECTRIC After forty-one years of service Harry B. Gilmore, secretary of the Western Electric Company, will retire on September 1, it is announced by the company's directors. He will be succeeded by Norman R. Frame, formerly assistant secretary, who was elected to his new post on July 13. Mr. Frame has been with the organization for twenty years. After he was graduated from Columbia University and the Albany Law School he practiced law for several years, joining the Western Electric Company in 1923. He served as attorney with the company and with its wholly owned subsidiary, Electrical Research Products, Inc. During 1926 he was attorney and secretary of the Graybar Electric Company, and on April 13, 1943, he was elected assistant secretary of Western Electric. WESTINGHOUSE RELEASES MOVIE AND ELECTRONIC ROOKLET An educational motion picture released by Westinghouse, "Electronics at Work," explains the six basic functions of electronic tubes and shows how each type ol lube is used in some of the latest industrial and military applications. Animated drawings are utilized, which show tube construction and explain how the cathode, anode and grid elements rectify, amplify, generate, control, transform light into electric current and transform Today -more than ever, thousands of exhibitors echo its* praises—, Come Victory, it* will be available again to the thousands more who know that it represents the utmost in projection arc lamps ?fr NATIONAL THEATRE SUPPLY Division of National &*&& -Bludworth, Inc.

The company also has published a 44page booklet describing electronic applications in industry, in the war, in medicine and the home. This illustrated work shows the various types of electronic tubes, key units of every electronic device, for such applications as industrial control, diathermy, power conversion, X-ray and radio. A copy of the booklet may be secured from Department 7-N-20, Westinghouse Electric and Manufacturing Company, E. Pittsburgh, Pa. AT YOUR SERVICE (Continued from page 19) to the other side where the blade makes contact along the same -wire. In this manner follow along each lead, taking in every splice or connection from the current source to the carbon holder. At the same time observe the ammeter on the lamp. If, on any of these tests, it is found that by-passing any connections with your test lead causes the ammeter to increase, that connection needs attention and should be cleaned and thoroughly tightened. If the rectifier or generator is located in another room at some distance from the arc, the wiring should be checked for size to determine whether or not it is of the proper carrying capacity as recommended by the manufacturer. Wiring from source to arc should be as short as conveniently possible and any unnecessary lengths should be removed to shorten the distance the current must travel. In many projection rooms both rectifiers are permitted to run for the duration of the show. It would mean a lot in the conservation of both current and rectifier tubes if the rectifier was cut off on the off-machine after each changeover. To do this, remove the switch from the d.c. circuit and feed the d.c. circuit directly to the lamp. Change the switch to the a.c. input circuit of the rectifier. — C. R. Shepard, RCA. Checking Alignment of Arc Lamps With three point pedestals, arc lamps are readily thrown out of proper position by bumping or vibration of machines. Lamps may be easily checked by removing lens tube and placing a flashlight in the lens holder. Sighting over the carbons from the rear of the lamp will readily show if lamps are in direct line with aperture and lens. A poor light at the edge of the screen which cannot be cleared by adjustment of mirror or carbons indicates that the lamp is not properly aligned. — R. S. Sear. RCA. 22 INTER1VATIONAL PROJECTIONIST
