The Commercial Exhibits

Abstract

As a result of the splendid co-operation of thirty exhibitors, the space reserved for commercial exhibits at the Joint Meeting of the American Roentgen Ray Society and the Radiological Society of North America was filled almost to overflowing. The exhibit space was adjacent to the scientific exhibits, and it was necessary to pass through it to reach the ballroom, where the morning sessions and the afternoon diagnostic sessions were held. The attendance at the commercial exhibits was excellent, giving the exhibitors an opportunity to demonstrate new equipment and methods, to renew old friendships, and to make new contacts with the more than 1,300 members and guests registered at the meeting. Your roving reporter (Chairman of the Commercial Exhibit Committee) attempted to make notes on all the exhibits, but the material was so extensive that it was impossible not to miss some points of interest. To appreciate the quality and extent of the exhibits, it is necessary to see them for oneself. Not to spend considerable time in the commercial exhibit section is to miss an important part of our scientific meetings. Many of the exhibitors have been producing materials of great value to the war effort, which for reasons of security they could not show, but the quality of the equipment displayed was up to pre-war standards, and the extent of the exhibits indicated that the difficulties in the shipping situation, which interfered with the size and quality of the exhibit at the 1942 meeting, had been largely overcome. A brief note concerning each of the exhibits follows: Ansco: In addition to the excellent line of photographic materials shown by Ansco, there were also exhibited specimens of the machine work turned out in their shops for the ordnance departments of our Armed Forces. Buck X-ograph Company demonstrated complete film processing tank layouts, with thermostatic controls. A new development, shown in the central portion of their exhibit space, was an ingenious wet film transfer cabinet for viewing wet films. Mr. Buck was in immediate charge of the exhibit. Canadian Radium & Uranium Corporation: This exhibit demonstrated radium and its applications from the ore to the finished product. Of especial interest was the radon-containing ointment which is being used in the treatment of radiation injuries and other intractable conditions. E. I. du Pont de Nemours & Co., Inc.: An extensive exhibit of du Pont products, of which there is an extremely varied assortment, was shown. A large spindle of Nylon thread brought forth many expressions of interest, especially from the lady visitors. Carl Patterson (Patterson Screens), an important addition to the du Pont Company, was on hand. Eastman Kodak Company: The use of “Kodacolor aero reversal film” in aerial photography was strikingly demonstrated by a long strip color photograph shown in a special demonstration at the front of the booth.
