Abstract
An apparatus for the listening to words representative of measurements of physical quantities according to which the measurements of said quantities are listened at time intervals controlled by a timer adjustable to operate at chosen time intervals, by means of at least one reading head reading recordings of said measurements, each obtained on the side surface of a revolving record cylinder along a circumferential track, said tracks being spaced away from each other at predetermined equal distances, the reading heads being associated with reproduction circuits.
Claims6
Apparatus for announcing messages representing measurements of physical quantities, comprising in combination:
- a record cylinder having a series of circumferentially extending record tracks thereon disposed in longitudinally spaced relation along said cylinder, each record track being circular such that the end thereof merges with its beginning;
- a read head mounted adjacent said record cylinder for movement into and out of pick-up relation with respect to said record cylinder and for movement along the length of said cylinder;
- means for causing said record cylinder to rotate on command and for an integral number of revolutions;
- means for causing said read head to move into pick-up position in consonance with rotation of said record cylinder and for causing said read head to move out of pick-up position in consonance with stopping of said record cylinder;
- timer means for continuously moving said read head along the length of said cylinder from one fixed position aligned with a particular record track to another fixed position aligned with another record track only when said pick-up head is out of pick-up position;
- and
- means for automatically resetting said read head in its starting position at the end of its longitudinal movement along said record cylinder.
