 (Photos)<\/a><\/p>\n\n\n\n



Although the Fourth of July cut this week to three days, Stefan Wipf compressed into this period not only a brilliant survey of the problems of instabilities and at effects in superconductors, but also a half-day review of the status of flux pumps. Particularly notable in the first category were the review papers by Hart of General Electric and by Chairman Wipf. Some very imaginative ideas in the field of superconducting transmission systems were outlined by Nahman of the Bureau of Standards who thinks not only of transmitting power but also of transmission in the same system of information and of cryogenic liquids.<\/p>\n\n\n\n
