Abstract
1,152,858. Electro-physical measurementdimensions. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. March 19, 1968 [March 22, 1967], No.13259/68. Heading G1N. [Also in Division H1] Local distances between a colour-selectionelectrode and the image-plane at the window of a C.R.T. are measured by temporarily inserting an insulating sheet 4, carrying electrode studs 5 between the selection-electrode 2 and the window 1, and measuring the spark-over voltage between the electrodes and the selectionelectrode. The studs may be of equal length and the contour calculated from the flash-over voltage, but preferably the studs are adjustable in length to the required contour as illustrated in Fig.3 (not shown) and the flash-over volt age should be within constant prescribed limits for each electrode.
