ELECTRONIC INDUSTRIES & Tele-Tech • August 1957 1 RADARSCOPE NEW TV BROADCAST PACKAGE offered by Hall- amore Electronics Co., a division of the Siegler Corporation, Anaheim, California, is a complete one- man TV program center. Included in the center is all equipment necessary to telecast live, filmed, or remote programs. The $15,000 package includes a master console, with combined audio and video con- trol equipment; both film and slide projection equip- ment; audio and record turntable facilities; one or more cameras, which can be operated by remote control from the master console; and all necessary transmitting circuitry. It is specifically designed for one-man operation, including controls so one man can operate cameras remotely—turning them on himself for commercial, news, or other announce- ments.

Early military applications are predicted by Naval Ordnance Laboratory workers, who see pos- sibilities of cheaper, smaller, and simpler electronic control systems. GIANT RADIO-TELESCOPE is being completed in England. It is the largest steerable radio-telescope in the world, is valued at more than $2 million. The reflector is 250 feet in diameter, weighs 750 tons, towers 215 feet above the ground. Tracking rate of this mammoth telescope is great enough to track the earth satellites to be launched during IGY. BREAKER POINTS are elimnated in the new igni- tion system developed by Commonwealth Engineer- ing Co., of Ohio. The new device is reportedly inexpensive, and small enough to be installed be- neath the dash of present vehicles without requiring any major changes in other equipment. 2 ELECTRONIC INDUSTRIES & Tele -Tech • August 1957 Analyzing current developments and trends throughout the electronic industries that will shape tomorrow's research, manufacturing and operation MORE VERSATILE ENGINEERS are needed for See You at WESCON! the growing technical revolution, says Willard F.
