Abstract

Data are recorded in a core memory 1 by coincident energization of selected input lines 2 and 3. Sense windings 4 provide a binary output. Cores 5 and 6 form part of a circuit which detects the energizing of more than one conductor 2 or 3 in the same plane.

Checking Circuit

Data are recorded in a core memory 1 by coincident energization of selected input lines 2 and 3. Sense windings 4 provide a binary output. Cores 5 and 6 form part of a circuit which detects the energizing of more than one conductor 2 or 3 in the same plane.

All lines 2 are connected to a winding 7 linking core 5. Similarly, all lines 3 are connected to winding 8 linking core 6. A signal on a single line 2 or 3 is insufficient to switch the corresponding core 5 or 6 and produce an error signal on a line 9, whereas, signals on two lines 2 or two lines 3 are sufficient to switch the corresponding core 5 or 6 and produce an error signal.
