A printing recorder for use in conjunction with scaling units
A R Lang · Journal of Scientific Instruments · 1952
The machine prints on a 6 in wide continuous paper roll the counts registered by the counter and neons of one or two scaling units, together with an angle, recorded as degrees and minutes. Closure of an external contact triggers a relay-controlled sequence of operations of printing and moving on the paper, counting by the scaling units being interrupted momentarily while printing takes place.
