Abstract: HARD MAGNETIC FERRITES OF THE FORMULA MO.6FE2O3 WHERE M IS BARIUM, STRONTIUM OR LEAD, ARE MADE BY PROVIDING A MOTLEN BORATE COMPOSITION CONTAINING THE METAL OXIDE AND FERRIC OXIDE IN AMOUNTS CORRESPONDING TO THE DESIRED FERRITE, COOLING THE MELT BELOW THE LIQUIDUS EITHER SO RAPIDLY AS TO CONVERT THE MELT TO A GLASS WHICH UPON APPROPRIATE HEAT TREATMENT UNDERGOES NUCLEATION AND CRYSTALLIZATION OF THE FERRITE, OR AT A RATE SUCH THAT DEVTRI-

FICATION AND FERRITE CRYSTALLIZATION OCCURS DURING COOLING. BOTH PROCEDURES RESULT IN A BORATE-RICH MATRIX CONTAINING THE CRYSTALLIZED FERRITE WHICH CAN BE EASILY RECOVERED SEPARATELY FROM OTHER MATRIX SUBSTANCES BY FOR EXAMPLE MAGNETIC SEPARATION OR DISSOLUTION OF THE BORATE MATRIX MATERIAL IN A WEEK ACID.

Abstract: A SELF-ALIGNING BEARING IS FORMED FROM A ONE-PIECE METAL MEMBER HAVIN GA TUBULAR CENTRAL PORTION FOR RECEIVING A ROTATING SHAFT, AND SUPPORTING END PORTIONS FOR THE TUBULAR PORTION INTEGRAL WITH ITS OPPOSITE ENDS. THESE SUPPORTING END PORTIONS ARE DISPOSED AROUND THE OUTSIDE OF THE TUBULAR PORTION AND ARE CURVED BACK OVER IT. THE OUTER SURFACES OF THE SUPPORTING PORTIONS LIE IN AN IMAGINARY SPHERICAL SURFACE HAVING ITS CENTER AT THE AXIS OF THE TUBULAR PORTION OF THE BEARING MIDWAY BETWEEN ITS ENDS. THIS BEARING IS MOUNTED IN AN OPENING THROUGH A BEARING SUPPORT PROVIDED WITH AN ENCIRCLING SIDE WALL CURVED TO FIT AGAINST THE OUTER SURFACES OF THE SUPPORTING END PORTIONS OF THE BEARING SO THAT THE BEARING CAN TILT IN THE OPENING IN ANY DIRECTION.
