through 2B. The interposer
magnet is energized at 86° (PS) through the decode
tree. The escape magnet is energized by the closing
of the interposer bail contacts. The escape-armature
contact energizes the escape-interlock relays.
The
punch clutch is energized through Pl, the escape-
interlock relays and P2.
In our example, we punched
a zero in card column 11, energized the interposer 0
magnet, escaped to column 12, and energized the
punch clutch.
Read-out, Punch-out Cycles 4, 5, 6 and 7: Cycles 4,
5, 6, and 7 are identical to cycle 3 in operation.
In our
example, we punched a 0 in column 12, energized the
interposer 4 magnet, and escaped to column 13 during
cycle 4. During cycle 5 we punch a 4, energize the
interposer 6 magnet, and escape to column 14. In cycle
6 we punch a 6 in column 14, energize the interposer 0
magnet and escape to column 15. In cycle 7 we punch
a 0 in column 15, energize a 7 interposer magnet, and
escape to column 16.
Read-out, Punch-out Cycle 8: During this cycle, the
information set up in cycle 7 is punched, the last digit
is transferred from the register 2B to register IA. The
interposer magnet is energized to allow the last digit
t-0 be punched on the next cycle. At 10° the informa-
tion in register 2B is transferred into register IA. At

86° the interposer magnet is energized through the
decode tree. The interposer bail contacts make, ener-
gizing the escape magnet at 180° (Pl). The escape
armature contact makes, energizing the escape-inter-
lock relays. The punch clutch is energized through P2,
interlock relays, and Pl. At 86° the information in
registers 8A through 2A is transferred to registers 8B
through 2B. All digits that were keyed in have been
read out; so all registers equal zero (no relays picked).
In our example, we punched a 7 in column 16, ener-
gized interposer 8 magnet, and escaped to column 17.
Read-out, Punch-out Cycle 9: Escapement to the
last column of the field ( detail card) and out of the
last column of the field (program card) happened in
the last part of cycle 8. This opens the starwheel 12
contact. All digits have been read out of storage, the
last digit will be punched on this cycle.
It
is necessary
to drop out the left-zero control relays during this
cycle. At 10° the punch-out relay 317 is dropped; after
the starwheel 12 contact opened, relay 317 was held
by P7 until 10° of this cycle. The
N/o
2-point of relay
317 opens, dropping read-out I (326). The
N/o
5-point
of relay 317 opens the circuit to the keyboard-restore
magnets, but the interposer bail contacts hold the
magnet until about 65°. The digit is punched, and
the punch clutch latches at 345°.
In our example, col-
umn 17 is punched with an 8.
