    Abstract: 684,318. Cathode-ray tubes. PHILIPS S ELECTRICAL, Ltd. May 19, 1949 [May 22, 1948; July 16, 1948], Nos. 13403/49'and 13404/49. Class 39(i) [Also in Groups XL(b) and XL(c)] A cathode-ray tube pulse distributer is used in a signalling system (see Group XL(c)). Regular pulses from a generator 1 are supplied to the grid electrode 72, acting as the anode, of a cathode-ray tube 63 and a control voltage from circuit 5 to the deflecting electrode 70. The beam thus strikes one of the secondary-emitting auxiliary-cathode targets 73, 74 depending upon the output from circuit 5. The target upon which the beam is directed follows the variations of potential of the anode 72 so that a pulse applied to the latter is repeated by one or other of the electrodes 73, 74.
