Radio age research, manufacturing, communications, broadcasting, television (1941)

Monitor screen (left) shows magnified images of living organisms picked up by combination of light microscope and sensitive Vidicon tube at right. ance also is known to be obser%'ed by this means. Class- room teaching is frequently made more effective via TV. Other fields for which the system is suitable and either in operation or considered for the near future are: Commerce and Banking — meetings (sales, stock- holder); shows, exhibits and demonstrations; office intercom; transmission of signatures, balances, records. Industrial Control and Testing — wind tunnel tests, [imc study, oven and furnace operation, smoke control, life tests, remote telemetering, inspection (processes, machines, gauges, etc.); plant intercom, transmission of prints, photos, drawings; foundry- and rolling mill opera- tions, training, materi.Us handling. Medical — surgery. X-ray transmission, training. Military — handling of explosives, rocket and guided missile performance, view of range finding, training. Security and Law Enforcement — patrolling, guard- ing, fingerprint transmission. Specialized Application — under-water work, TV rehearsals, fire control, forestry conservation, rescue work, radiation and nuclear research. Traffic Control — streets, railway yards, bus and tnick terminals, ships and docks. In other words, wherever it is desirable to view at a distance a clear, exact, instantaneous picture under conditions where direct observation is too dangerous, or the arena of action too inaccessible, too inconvenient or too expensive, industrial TV is the solution. Design of RCA's ITV system centers around a new camera rube, the Vidicon. It is two-thirds as sensitive as the srudio-t}-pe image orthicon, costs only one-third as much. The ch.un consists of a miniature camera, about die size of a 16 mm. movie camera, and a conip.ict control monitor connected by 500 feet of 18-conductor camera cable, .625 inches in diameter. The connecting cable transmits the picture picked up by the camera to the control monitors 10-inch view- ing screen. The complete chain operates from ordinary 115-volt, 6Q-c7cle power (50-c7cle equipment is .ilso available), and is entirely self-contained. Power con- sumption is only 230 watts. The RCA industrial television camera is as easy to handle as the average 16 mm. movie camera. It contains only three tubes, one of which is the Vidicon. The small size explains why the camera can be placed in spots inaccessible to humans. The monitor, together with its own power supply .ind control panel, is housed in a metal case smaller than the average table-model TV set (20" deep, 15" high, 13" across). The optical-focus control operates a small reversible motor, which changes lens focus. Interlocking safet)' switches and a complete shielding unit permit [>eople to work on the equipment in abso- lute safety. Though a standard set is supplied with 50 feet of camera cable, the monitor may be located at any point within 500 feet of the camera by the addition of extra cable, supplied on special order. For applications requiring more than one viewer, or where the distance from the camera must be greater than 500 feet, the control monitor has been equipped with provisions for plugging in additional receivers. Where distances between monitor and auxiliary viewers are extreme, the RCA system is so designed that it can be operated with microwave transmission or by means of coaxial cable. Scockholdcrs Tour" Plant (Continued jrom page 12) of television. Bliss predicted that TV will become a valued tool of business and industry for such purposes. "It provides a unique means of showing stockholders what is being done with their money and how their investments are being protcaed and enhanced," he said, "without wasting their valuable time and energies and those of company officials in traveling from point to point. "Further, it makes it possible to present a dramatic vignette of highlights in a company's operations that is more impressive and understandable than a physical tour of the plant. It presents the company's story with more realism and conviction than film can .ichievc, since it is recognized that there is no window dressing in a TV presentation—no opportunity for nitting and editing."
