Class Information
Number: 315/377
Name: Electric lamp and discharge devices: systems > Cathode ray tube circuits > Cathode-ray deflections circuits > With marker
Description: Subject matter wherein the cathode-ray tube includes a cathode-ray beam source, fluorescent target, and a marker circuit whereby the cathode-ray beam is caused to produce a periodically recurring indication pattern, or marker on the fluorescent target by the effect of the marker circuit on the cathode-ray beam, when the marker circuit is energized.
