An electromagnet includes a lightweight movable body in the form of a hollow cylindrical body. The resistances of circulation paths for eddy currents flowing in the movable body due to electromagnetic induction are increased to suppress the eddy currents. Excitation coils are connected parallel to each other to reduce the coil inductance for increasing the magnetic forces to attract the movable bo...

The invention deals with improvements in doffing of yarn packages and insertion of bobbins (either conical or cylindrical) into the cradle mechanisms of operating stations of a yarn handling machine including definition of the insertion path, retention of the bobbin relative to the operating station while axiilary operations such as formation of a thread reserve are performed, and control of the i...

A method for forming intermetallic and intermetallic-type precursor alloys for subsequent mechanical alloying applications. Elemental powders are blended in proportions approximately equal to their respective intermetallic compounds. Heating of the blend results in the formation of intermetallic compounds whereas lack of heating results in intermetallic-type powder without the intermetallic struct...

In a method of manufacturing accumulator plate sets separator sheets (15) consisting of glass fleece are cut to size and are adhesively bonded to form pockets after being folded around a positive grid plate laid thereon. A predetermined compressive stress is maintained in the plate set (18) by bands (21) placed around it, whereupon the plate sets are then inserted into an accumulator housing (20).
