Abstract
477,043. Oscillographs. RADIOAKT.- GES. D. S. LOEWE. June 19, 1936, No. 17138. Convention date, June 20, 1935. [Class 37] [Also in Group XL] Cathode-ray tubes applicable to measurements by the 3-voltmeter method as on 3-phase mains and in cardiographs have three separate cathode rays deflected separately in one direction by plates 7 which may be interconnected at 7<1> and deflected together in the other direction by plates 12 or coils. Each image point on the screen 8 is a reproduction of a diaphragm aperture 1 using a separate cathode 3 and separate electron lens 4, 5 the electrodes of which are each biassed more positively than the adjacent electrode in the direction towards the cathode. To space the image points on the screen by a distance equal to the maximum deflection the electrode systems are sufficiently spaced or inclined or the plates 7 are biassed to bend apart the mean paths of the rays. Specifications 432,485 and 451,745, [both in Group XL], are referred to.
