MECHANICAL AND ELECTRICAL PRINCIPLES
THE MECHANICAL principles of the Type 80 Sorter
are identical to those of the Type S2.
The electrical principles of the Type 80 machine
differ somewhat from those employed in the Type 82.
No tubes are present in the Type SO machine; there-
fore, the use of a time delay relay to allow time for
tubes to heat up is not necessary. A high speed slate
base relay is employed in place of tubes to aid
In
controlling the energization of the sort magnet.
When a hole is sensed in the card, a circuit is com-
pleted to energize the sort magnet and cause pickup
of a high speed slate base relay. This circuit is con-
trolled through the card brush and the inner and outer
brushes on the commutator. Pickup of the high speed
relay closes its contact point and maintains a hold
circuit to the sort magnet through the center and outer
commutator brushes. This hold circuit continues until
slightly after the 12 position on the card has passed
under the reading brush, thus completing the sensing
of any holes in that column. As on the Type 82
machine, if two holes are present in a column sensed,
and rio provisions are made by means of the contact
bars on the commutator to suspend sorting of one
value, the card will sort according to the first value
sensed by the brush.
