Density trace made with computer printout
Special drum for a computer-controlled printer improves density trace of scientific data. The drum provides uniformly shaped characters and evenly spaced variations of print density that precisely reflect data magnitude. This device plots temperature profiles, geographic contours, pressure gradients, electric potential gradients, and magnetic field configurations.

Vibration tests on vidicons made by improved method
Sensitive method is used for checking the performance of vidicons in mechanical vibration tests. The image of the desired fine-detail test pattern is stored in the photosensitive surface of the vidicon while the system is free of mechanical vibration. Mechanical excitation is then applied, and its effects observed.
