Millikan Tube. Members of the Radiological Society of North America meeting in Pasadena gave Dr. Robert Andrews Millikan, chairman of California Institute of Technology, a gold medal for a powerful X-ray source developed in his laboratories. The new 650,000-volt tube, the work of Dr. E. C. Lauritsen, is the most powerful ever demonstrated. Dr. William David Coolidge in General Electric Laboratories, Schenectady, has been experimenting for the past year with a 900,000-volt tube not yet perfected for demonstration. Hospitals today use a 200,000-volt tube. Five billion dollars worth of radium (20 Ib.) would...
...attention has just been called to an article at the bottom of p. 58 in the Nov. 3 issue of TIME in which the statement is made that, "coppermen noted with fear that last fortnight International Paper & Power Co. completed a 126-mile 220,000-volt transmission line made of aluminum wire, first important one of its kind in the U. S." I do not know your source of information for this statement but the statement as it stands is incorrect. Our records show that during the last ten years-the period of time in which 220,000-volt lines...
...talk that the lowest price in recent history, 1894's 9?, may be seen again. No company could make sizable profits at that price, many could make none. And coppermen noted with fear that last fortnight International Paper and Power Co. completed a 126-mi., 220,000-volt transmission line made of aluminum wire, first important one of its kind...
...rays into photographic appliances or other aparatus that they would harmfully affect. The basment is to be equipped with double walls which will prevent outside disturbances from affecting the extremely delicate measurements essential to research. Rooms will be sound proof and of constant temperature. A huge, 100,000 volt storage battery, one of the largest of its kind in the world, will also be situated underground...
...start them glowing. Last week Raymond R. Machlett, 30, Manhattan electrical engineer who, when he was 26, was one of the first to develop a commercially satisfactory Neon tube, announced that by altering the construction slightly, he had been able to light a neon lamp with a 220-volt current, the ordinary household voltage. Present tubes require a 10,000-volt current, expensively stepped-up from service current by transformers...
