Projection Engineering, September, 1929 Page 5 operating with electrical engineers on RESISTANCE PROBLEMS This complete staff of resistance specialists at your service. A standard Durham Metallized resistance unit, made in a wide variety of ranges and used by the millions in the radio industry. W E mean "at your service" in the broadest sense of the term, for our staff of resistance engineers are glad to extend the full facilities of our laboratory to help solve any resistance problem in connection with any type of electrical work. This organization has long been recognized as the leading producers of resistance units in the country for radio, television, sound amplification, talkie-movie apparatus, X-ray and other work requiring precise design and manufacture. DURHAM RESISTANCES are now standard equipment with many of America's foremost manufacturers of radio and allied equipment, and are also used and endorsed by various departments of the United States Government. We are constantly working in cooperation with the engineers of large manufacturing companies and experimental laboratories and now wish to take this opportunity to invite all engineers to take full advantage of our broad service, which encompasses an equally wide experience.
