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.
