Abstract: A soft magnetic article is disclosed which is formed of an alloy consisting essentially of, in weight percent, about______________________________________ C 0.003-0.02 Mn 0.10 max. Si 0.10 max. P 0.01 max. S 0.003 max. Cr 0.1 max. Ni 0.2 max. Mo 0.1 max. Co 48-50 V 1.8-2.2 Nb 0.15-0.5 N 0.004 max. O 0.006 max. ______________________________________with the balance essentially iron. The article is annealed at a temperature of not more than 740.degree. C. (1364.degree. F.) for not more than about 4 hours and provides a room temperature yield strength of at least about 620 MPa (90 ksi) in the annealed condition. Among the disclosed embodiments of the annealed article according to this invention are a rotor and a stator for a rotating electrical machine such as a motor, generator, alternator or a magnetic bearing.

Abstract: A skylight system is formed of preglazed modules which are arranged side-by-side in a grid-like array which is supported on an underlying beam structure. The preglazed modules have slideably interfitting edges for joining to adjacent modules along all four sides of each module. The preferred modules are attached and are supported on corners thereof to the underlying beam structure. The interfitted edges allow slight relative shifting to accommodate expansion or contraction due to thermal conditions. Preferably, the modules may be supported and arrayed to define a flat surface or a predetermined curvature for the skylight. Broken glazing panels may be replaced in a given preglazed module. Gutters on adjacent modules are joined to provide a continuous moisture removal system.
