Abstract

Elimination of time delay components utilized with circuits incapable of handling sequential input information has been accomplished by provision of discrete isolation areas within a multipath magnetic core structure. Many different winding techniques permit almost every binary switching function to be realized.

Magnetic Multipath Logic

Elimination of time delay components utilized with circuits incapable of handling sequential input information has been accomplished by provision of discrete isolation areas within a multipath magnetic core structure. Many different winding techniques permit almost every binary switching function to be realized.

With reference to the left-hand component, a multipath magnetic core structure is shown divided into six legs, each of which has the same cross- sectional area, and are numbered 1 through 6. An energized reset winding provides a downward flux direction in legs 1, 2 and 4 and an upward flux direction in legs 3, 5 and 6. An energized Y input winding provides an upward flux in leg 2. The X input winding provides a downward flux in leg 3 when energized. An energized drive winding causes an upward flux direction in legs 4 and 5 and functions to provide an induced output signal on an output winding. This links the leg 6, if the flux in either the legs 4 or 5 is in the downward direction. If the Y input winding is energized before the X input winding, the flux in leg 2 is reversed to an upward direction. This causes the flux in leg 5 to assume a downward direction, since the minimum flux path linking the legs 2 and 3 is much greater than the maximum flux path linking the legs 2 and 5. Energization of the X input winding causes flux reversal in leg 3 and reverses the flux in leg 4. If the X input appears alone, there will be no output engendered, when the drive winding is energized and the structure then performs the logical function of IF THEN. By rearranging...
