CCURATELY guided missiles, rockets, and space-exploring vehicles require instruments and apparatus which operate with accuracies undreamed of even a few years ago. Precision requirements are such that even primary standards must be re-evaluated. A major advance in this area occurred in August when the National Bureau of Standards dedicated its Electronic Cali­ bration Center at Boulder, Colo. T h e new facility, associated with the Radio Standards Laboratory, provides govern­ ment, industry, and the military services with access to t h e nation's primary elec­ trical and electronic standards. The primary standards are used to cali­ brate master working standards which are used, in turn, to calibrate instruments used in research laboratories and on pro­ duction lines. NBS feels that its new $2.5 million calibration facility will help it to meet the ever-increasing need for still greater accuracy of measurement and for more precise electronic standards and instru­ ments. T h e new laboratory expects to calibrate about 3000 pieces of equipment a year for the defense agencies alone. This is expected to increase substantially over the next few years. In the electrical field, where the art has advanced beyond t h e wildest dreams of early research workers, continued prog­ ress in research and development will depend on standardized terminology, ade­ quate basic standards, and standardized measuring devices. Some of the areas requiring attention were outlined in a 3-day Conference on Electronic Standards and Measurements, held in conjunction with the dedication of the calibration center. T h e meeting was sponsored by NBS, the American I n ­ stitute of Electrical Engineers, and the Institute of Radio Engineers. T h e pro­ gram covered such topics as standards and measurement techniques for frequen­ cies from direct current into the micro­ wave region, relation of primary stand­ ards to physical constants, and the most effective methods of organizing and op­ erating a standards laboratory. Research on electronic standards has not kept pace with the rapid develop­ ments of the electronics industry. As a result, individual laboratories have had to set up their own reference standards which differ from those of other labo­ ratories.

AIR-DRAW FURNACE Temperatures

to 1250° F.

Forced high-speed air circulation as­ sures fast, uniform heating to 1250° F. A heat-resistant, r e m o v a b l e alloy baffle directs the flow of air from the high-speed fan into t h e work chamber and back to the intake of the fan. Removable alloy s h e l v e s placed at various levels in the heat­ ing chamber provide extra capacity and versatility. All the necessary temperature indication and control­ ling i n s t r u m e n t s are conveniently mounted in the pyramid base. Cham­ ber size — 7 in. wide, 12 in. long, 7 in. high. C h o i c e of either 230 or 115 volts AC. Price
