Abstract: 1,029,010. Superconductive devices; electromagnets. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. Sept. 21, 1964 [Sept. 24, 1963], No. 38386/64. Headings H1K and H1P. [Also in Division F2] A magnet 1 is caused to float in a stable position and direction above a superconductive plate 2 by forming the plate with two magnetic apertures 3, 4 spaced apart by a distance 7 approximately equal to, but preferably 10% less than, the distance 6 between the magnet poles. The magnet or electromagnet can rotate freely about its longitudinal axis and thereby form a magnetic bearing. The plate 2 can be cup-shaped or comprise a mosaic of small plates of superconductive material on a substrate. The plate is made of a niobium-tin alloy.
