2. Both cards then feed simultaneously past the next station in their respective unit. At this point, the source card is read by the com-paring brushes, and impulses representing digits.

punched are directed to the comparing magnets by wiring the comparing brush hubs of the field being reproduced to one side of the comparing unit. At the same time, the reproduced card will be read by the punch brushes, and impulses representing digits punched are directed to the corresponding magnets by wiring the punch brush hubs of the reproduced field to the other side of the comparing unit. Thus, if the two impulses received by a particular comparing position are the same, reproducing has been performed satisfactorily. If the impulses dif-fer, or if only one magnet is a comparing posi-tion has received an impulse, an error is indi-cated. The machine stops and the comparing position in which the error is located is iden-tified by the comparing indicator.

Any comparing position can be used to verify punching in any given column, but the pOSitions corresponding to the columns in the reproduced card are generally usedo This pro-vides for ease in wiring, as well as simplifying the process of finding the error column.

Selective Reproducing And Comparing

Selective reproducing is the process whereby only one type of card, X or NX, will be repro-duced. The reproducing switch and the selective reproducing GP and compare switch must be is the same as for straight reproducing.

2. In order to identify the X cards, a read X brush is set to read the column containing the X punch, and the corresponding readXbrush hub on the control panel is wired to the PX hub.

The PX circuit then sets up the conditions under which reproducing and comparing can be performed, in conjunction with the detail-master switch, as follows:

X Elimination or Transfer

Column splits operate on the same principle as those in the type 557 interpreter. They allow the reading of a column to be divided between the zero and 11 punching positions in order to separate the reading of control punches from digit punches, or to combine these punches from different columns into one column. Figure 7-7 shows three uses for column splitso

other punch magnet, if desired. The comparing brush must be wired through a column split in . the same manner in order to avoid a false error light during comparison.

2. The column split may also be used for combining punches. The reproducing brush hub representing the control punch is wired to the 11-12 hub, and the digit punch from another . column is wired to the 0-9 hub. The common hub is then wired to a punch magnet, where the two punches from different columns are punched into one column. The comparing brushes fo r fieldo This can be accomplished by wiring the

Gangpunching from a single master card does not. require the use of a control punch to identify the master or detail cards. Verification of punching should be performed by visually com-paring the master card with the last detail card punched as each handful of cards is removed from the stackero

Where information to be gangpunched changes from one group of cards to the next, inter-spersed gangpunching may be employed. This could be in the form of straight or offset

gang-149

punchingo A different master card is placed in front of each group of detail cards. Gang-punching and comparing are then controlled by the presence of a control punch in either the master or the detail cardso Each feed unit is allowed to operate independently of the other for gangpunching operations by turning the reproducing switch OFF.

The selective reproducing and gangpunch compare switch must be turned ON in order for the gangpunching operation to be comparedo Straight Intersperse Gangpunching

Cards to be gangpunched are placed in the punching unit. After a handful has been punched, they may be compared for accuracy of gang-punching by placing them in the reading unit. Fig-ure 7-8 illustrates the wiring for interspersed master card gangpunching and comparing.

1. Information to be gangpunched is wired from the punch brushes to the punch magnets.

This permits each card to pass the punched information to the following card. The punch brushes must be wired to the corresponding punch magnets, column for column.

2. A punch X brush is set to read the column containing the control X, and the corresponding PX brush hub on the control panel is wired to the PX hub. This causes either X punched cards or NX punched cards to be gangpunched, depend-ing upon the settdepend-ing of the detail-master switch.

If master cards contain the control X, the detail-master switch must be set to MASTER. If detail cards are punched with the control X, the detail-master switch must be set to DETAIL. Punching is then controlled by the detail-master switch as follows:

a o When set to MASTER, punching is sus-pended when X punched master cards are passing under ~he punch magnets. This prevents a master card from being punched with information contained in the last detail card of the preceding group. All NX detail cards are gangpunched.

b. When set to DETAIL, punching is sus-pended when NX master cards are passing under the punch magnets. This prevents a master card from being punched from the preceding detail card. All X punched detail cards are gang-punched.

3⁰ In order to compare the gangpunched cards, the compC\ring brushes are wired to one side of the comparing unit and the reproducing brushes to the other side. The wiring allows information punched in one card to be compared with the information in the following card. If

4. The control field is wired for comparing to ensure that the appropriate detail cards follow their respective master card. If a master card is missing, or if a detail card has been misfiled or punched with the wrong control data, an error will be signalled.

5" A read X brush is set to read the column containing the control X, and the corresponding read X brush hub is wired to the RX hub. This causes comparing to be performed under the control of the detail-master switch, as follows:

a. If the Control X is punched in the master cards and the detail-master switch is set to MASTER, comparing is suspended when the X punched master cards are passing the repro-ducing brushes. This prevents a master card from being compared with the last detail cardof the preceding group. All NX detail cards are being cOmpared with the preceding detail card.

All X punched detail cards are compared.

Offset Intersperse Gangpunching

In order to differentiate between straight and offset intersperse gangpunching, the origin of impulses must be selected either from punch brushes 25-29 or 35-39 (see fig. 7-9).

Since the punch brushes (for gangpunching) and comparingbrushes (for comparing) cannotbe deactivated, a device must be available into wiring for offset gangpunching and comparing is described in figure 7-9.

1. If the card containing the X is the master card, punch brushes 25- 29 are wired to the transferred hubs of selector #1, and the normal hubs of selector #1 are wired from punch brushes 35-39 for the column to be punched in

the detail cardso The column to be punched in the detail cards is wired from the common hubs of selector #1 to punch magnets 35-390

20 To prevent the master card from being punched from the last detail card of the pre-ceding group, a punch X brush is placed on the proper column to pick up the master X puncheso

The outlet hub that corresponds to that particular punch X brush is wired to the PX hub.

3. The PD is wired to the P pickup hub of the selector to control the selector when the X punched master is at the punch brushes.

Offset Intersperse Gangpunch Comparing In order to compare offset intersperse gang- ..

punching, another class selector must be are· wired to the comparing magnets to compare with the field punched in the detail cards, as read by the reproducing brushes.

Summary Punching

For summary punching operations, the re-producing punch must be connected to the ac-counting machine by a summary punch cable.

Cards to be punched are placed in the punching unit. One depression of the start key causes a card to feed past the punch magnets. From then on, feeding is controlled by the accounting

ma-chine. When a change occurs in the control for which summary totals are to be punched, the accounting machine stops and the reproducing punch operates for one card cycle. After this summary card is punched, the accounting ma-chine continues feeding cards to accumulate totals for the next control group.

MACHINE ACCOUNTANT 3 & 2 When the reproducing punch is connected to

the accounting machine for summary punching, the control panel hubs representing entries to both sides of comparing unit positions 41 through 80 become exits for totals which have been accumulated in counters in the accounting ma-chine. These totals can be punched by wiring im-pulses identical to those obtained from punches in the card. By reference to figure 7-8, G 1-10 and H 1-2, you will notice a hub for each punch-ing position in a card. Each hub in turn emits an impulse whenever the corresponding punching position of the card is passing under the punch magnets. When wired to the punch magnets as seen in figure 7-10, they cause the particular digits wired to be punched. Since these hubs do not emit when the first card is under the punch magnets, a blank card should be placed in front of the deck. Emitting can be performed in con-junction with other machine operations without affecting the particular operation involved.

Double Punch and Blank Column Detection

The double punch and blank column detection device, although standard on a machine equipped . for mark senSing, can be installed on other by turning the corresponding blank column

switches ON.

Mark Sensing

The mark sensing device is a special feature which may be installed in reproducing punches.

The number of pOSitions that may be installed conductive, pencils with special leads containing _ a high graphite content must be used for

mark-ing.

Each mark sense position covers three card columns. Marks placed in these positions are read as they pass the mark sense bru~hes, lo-cated in the punching unit between the punch X brushes ,and punch magnets, or the mark sense brushes located in the reading unit, between the read X brushes and the reproducing brushes.

Because marks are not suffiCiently conductive to permit direct operation of the punch magnets, an amp;iifying unit must be used. When the mark senSing switch is ON, the last 20 comparing positions on the control panel become mark sensing IN and OUT hubs. The mark senSing brushes corresponding to the positions marked are wired to the mark sensing IN hubs,which represent the entrance to the amplifying unit, and the mark sensing OUT hubs are wired to the punch magnets.

The only difference between the mark sensing brushes in the reading unit and those in the punching unit is that, when the brushes in the reading unit are used, the information is punched into cards other than those that are marked.

The wiring is the same.

Verification of mark sensing is performed by wiring the punch brushes representing the
