paper speed

I hand- cranked it until the strip caught properly and then pressed a button and watched the Sunday paper speed by in a blur.

Faster paper speeds can be used, for example, to resolve finer detail in the ECG.

On all pneumatic player pianos, the paper is pulled on to a take-up spool, and as more paper winds on, so the effective diameter of the spool increases, and with it the paper speed.

The duration of the nadir could only be graded into coarse divisions of less than one second, one to two seconds, or more than two seconds as the paper speed at which the recordings were made did not allow greater accuracy.

The His/Purkinje specialized muscle cells coordinate the depolarization of both ventricles, and if they are working efficiently the QRS complex is 80 to 120 ms in duration (represented by three small squares or less at the standard paper speed of 25mm/s).

Player piano engineers were well aware of this, as can be seen from many patents of the time, but since reproducing piano recordings were generally made with a similar take-up spool drive, the tempo of the recorded performance is faithfully reproduced, despite the gradually increasing paper speed.

Expired CO 2 curves were then recorded at a paper speed of 50 mm/s, and only tracings demonstrating a clear end-expiratory plateau, defined as a constant CO 2 value for more than 0.5 s at end-expiration, were used to determine P ET CO 2 .
