Monitor screen (left) shows magnified images of livingorganisms picked up by combination of light microscopeand sensitive Vidicon tube at right.ance also is known to be obser%'ed by this means. Classroomteaching is frequently made more effective via TV.Other fields for which the system is suitable andeither in operation or considered for the near future are:Commerce and Banking — meetings (sales, stockholder);shows, exhibits and demonstrations; officeintercom; 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 ofprints, photos, drawings; foundry- and rolling mill operations,training, materi.Us handling.Medical surgery. X-ray transmission, training.Military — handling of explosives, rocket and guidedmissile performance, view of range finding, training.Security and Law Enforcement — patrolling, guarding,fingerprint transmission.Specialized Application — under-water work, TVrehearsals, fire control, forestry conservation, rescue work,radiation and nuclear research.Traffic Control — streets, railway yards, bus andtnick terminals, ships and docks.In other words, wherever it is desirable to view ata distance a clear, exact, instantaneous picture underconditions where direct observation is too dangerous,or the arena of action too inaccessible, too inconvenientor too expensive, industrial TV is the solution.Design of RCA's ITV system centers around a newcamera rube, the Vidicon. It is two-thirds as sensitiveas the srudio-t}-pe image orthicon, costs only one-thirdas much.The ch.un consists of a miniature camera, about diesize of a 16 mm. movie camera, and a conip.ict controlmonitor connected by 500 feet of 18-conductor cameracable, .625 inches in diameter.The connecting cable transmits the picture pickedup by the camera to the control monitors 10-inch viewingscreen. The complete chain operates from ordinary115-volt, 6Q-c7cle power (50-c7cle equipment is .ilsoavailable), and is entirely self-contained. Power consumptionis only 230 watts.The RCA industrial television camera is as easy tohandle as the average 16 mm. movie camera.It containsonly three tubes, one of which is the Vidicon. The smallsize explains why the camera can be placed in spotsinaccessible to humans.The monitor, together with its own power supply.ind control panel, is housed in a metal case smaller thanthe average table-model TV set (20" deep, 15" high,13" across). The optical-focus control operates a smallreversible motor, which changes lens focus.Interlocking safet)' switches and a complete shieldingunit permit [>eople to work on the equipment in absolutesafety. Though a standard set is supplied with 50feet of camera cable, the monitor may be located at anypoint within 500 feet of the camera by the addition ofextra cable,supplied on special order.For applications requiring more than one viewer,or where the distance from the camera must be greaterthan 500 feet, the control monitor has been equippedwith provisions for plugging in additional receivers.Where distances between monitor and auxiliaryviewers are extreme, the RCA system is so designed thatit can be operated with microwave transmission or bymeans of coaxialcable.ScockholdcrsTour" Plant(Continued jrom page 12)of television. Bliss predicted that TV will become avalued tool of business and industry for such purposes."It provides a unique means of showing stockholderswhat is being done with their money and how theirinvestments are being protcaed and enhanced," he said,"without wasting their valuable time and energies andthose of company officials in traveling from point topoint."Further, it makes it possible to present a dramaticvignette of highlights in a company's operations that ismore impressive and understandable than a physical tourof the plant. It presents the company's story with morerealism and conviction than film can .ichievc, since it isrecognized that there is no window dressing in a TVpresentation—no opportunity for nitting and editing."RAD\0 ACE 2J
