Abstract
A magnetic suspension device or bearing employing permanent magnets (see Groups XXXIV and XXXV) has means which compensate for variations of flux due to alterations in the ambient temperature. These means are made of alloys containing either approximately 70 per cent nickel and 30 per cent copper, or 30 per cent nickel and 70 per cent iron; such alloys are magnetically non-permanent, have low magnetic permeabilities and negative temperature coefficients of permeability. It is stated that like alloys are known which have relatively linear temperature coefficients of permeability from -20 DEG to 100 DEG F. Specification 550,788, [Group XXXVI], is referred to.
