such leading movie producers as Warner Brothers, Cohimbia, RKO. Republic, 20th Century Fox, Walt Disney, The March of Time, and Pathe News. Abroad, British pic- tures have been predominantly RCA recorded, while in Latin America, studios are eiiuipped al- most exclusively by RCA. Today. RCA is the only organization ac- tively engaged in every phase of motion picture sound, from the studio to the theatre. In the war program, RCA the- atre and film recording equipment has been playing a vital role, being used to make and to screen sound motion pictares for entertainment, training and orientation of troops, and for combat records to aid in the shaping of war strategy. New Picture Projector Of particular interest among de- velopments in design and construc- tion which have sprung directly from wartime requirements is the new RCA 16 mm. projector devel- oped for the U. S. Signal Corps. Shock-mounted on rubber in a tough plywood case, this projector has been engineered to function even after being dropped on a con- crete floor from a height of 18 inches. Another major war contri- bution is RCA's Magicote lens- coating process. Before the war this process provided improved lenses for motion picture cameras and projectors. Now it is helping to provide superior binoculars, tele- scopes, and fire control apparatus for American troops. Not confined to the entertain- ment field, electronic sound now reaches into nearly every phase of human e.xperience. Installations of equipment for sound amplification and inter-communication have been made in restaurants and dining rooms, baseball parks, department stores, transportation terminals, hotels, banks, and night clubs. RCA sound systems are also in- stalled in power plants, courtrooms, prisons, and police stations. Sound Systems in Churches Many churches now have RCA sound systems, supplemented by the new 26-note carillon which takes the place of costly and space- consuming bells. Schools are other users of RCA sound equipment, in- cluding 16 mm. sound films, for instruction and entertainment. The RCA Telekom System is installed in many business offices, providing instant, quiet inter-communication which saves time and reduces the load on telephone facilities. In the 1930's the RCA plant broadcasting and industrial music system was born in the Harrison, N. J., plant of RCA Victor. Instal- lations have since been made in leading steel, chemical, textile, automotive, shipbuilding, aircraft plants, U. S. Navy Yards, and other vital industries. Shortly before the war, RCA be- came active in the field of elec- tronic power heating, that is, heat- ing with high-frequency power obtained from an electron tube os- cillator. Urgent demands of war production have since dictated the direction of development in this field. Even in its short history, electronic heating has made pos- sible dramatically increased accu- racy, thoroughness, efficiency, and speed in such processes as molding and bonding of plastics and wood products; case-hardening, welding, soldering, annealing, and temper- ing of metals; seaming of fabrics; and drying of textile yarns. As with electronic heating, so with every phase of radio, sound, and electronics, RCA scientists and engineers have pioneered in his- tory-making advances. The price- less experience and skill which has thus been accumulated during the past twenty-five years insure even greater RCA industrial and sound products for the next quarter-cen- tury of progress. Coastal Station Opens Radio station WPA of Radio- marine Corporation of America, located at Port Arthur, Texas, re- sumed operations with ships at sea on October 15 by authority of the Federal Communications Commis- sion. Serving the Port Arthur area and the Gulf of Mexico, station WPA, operates on both short and long range channels allocated for marine communication. It is the third of twelve Radiomarine coastal sta- tions, closed since the early days of the war, to resume ship-to-shore radio telegraph service as now need- ed for the safety of men and ships. Last February Radiomarine re- sumed operation of WNY, New York, and WOE, Lake Worth, Fla., for commercial message traffic. RCA IS A LEADER IN APPLYING ELECTRONICS TO NON-COM MUNICATIO.N'S PURPOSES.
