Operation (Sequence Chart)
Sort and Count (Figures 63, 64, and 65)
OBJECTIVE: A simultaneous sort and count operation. The
count-only switch (Figure 63) is in the OFF position, the count
switch is in the ON position. This changes the sort circuit, but
the principles remain the same.
1.
A +150v through CI, octal plug pin 4, is applied to the
main anode (pin 5) of the OA4G.
2. Reading a hole in the card permits a circuit from +150v,
CI, RI13-3N/o, common brush, contact roll, card brush,
R113-2N/O, count only switch, commutator inner brush,
commutator outer brush, RI13-5N/O, C6, octal pin plug 5
to pin 7 OA4G (starting anode). This causes the OA4G
to go into conduction.
3. At the same time a circuit is available from + 150v, CI,
R113-3N/O, common brush, contact roll, card brush, RI13-
IN/O to the number 2 grids of all the counter tubes.
4. Refer to items 2 through 5 in the preceding section for the
remainder of circuit.

condition circuits for counting operation.
RI13-1NjO
closes to provide a circuit to grid 2 of
all counter tubes.

R113-3NjO
provides a circuit from CI to the com-

R113-4Njc
opens the circuit from the main anode

provides plus potential to the outer
brush of the commutator with the counter switch off.
