Abstract

The mechanism includes electromagnet 10 having north pole 10a and sout pole 10b with flat pole surfaces 10c and 10d between which magnetic core assemblies 12 are disposed. The magnetic flux between poles 10a and 10b effectively causes core assemblies 12 to have a separating force between them so as to space core assemblies 12 along supporting spindle 14.

Magnetic Ferrite Core Separating Mechanism

The mechanism includes electromagnet 10 having north pole 10a and sout pole 10b with flat pole surfaces 10c and 10d between which magnetic core assemblies 12 are disposed. The magnetic flux between poles 10a and 10b effectively causes core assemblies 12 to have a separating force between them so as to space core assemblies 12 along supporting spindle 14.

Core assemblies 12 are disposed in cleaner tank 16 having cleaning fluid 18 disposed therein, and removable spindle 14 is anchored in the sides of fixture 10. Ultrasonic vibrator 20 is located in tank 16 and agitates the fluid 18 so as to clean core assemblies 12.

Each of the core assemblies 12 has ferrite parts 12a and 12b, and ferrite parts 12b have channels 12c formed into them. Spindle 14 passes through the channels 12c.

Core assemblies 12 also include channeled ceramic pieces 12d, and pieces 12a, 12b and 12d are fastened together, such as by molten glass. Core assemblies 12 are subsequently cut along lines 12e and 12f, and the portions of the pieces 12a, 12b and 12d between the cut lines 12e and 12f are discarded. The junctions 12g and 12h, after this cutting along lines 12e and 12f, form the magnetic gaps in the subsequently used magnetic cores, with each of the assemblies 12 providing two such cores, one with gap 12g and the other with gap 12h. Assemblies 12 are extremely thin, such as between five thousandths and fifteen thousandths of an inch in thickness, and t...
