[Class 39 (i)] A television Braun tube in which the picture screen is scanned by deflecting the ray in directions at right angles by two main deflecting plate systems is provided with auxiliary deflecting means between the main plates and the cathode so that the points of the screen struck by the ray when the main deflecting potentials are zero lie outside the picture area. The cross at the centre of the image, due to positive space charge in gas-filled tubes, is thus avoided. In a tube with cathode K, Wehnelt cylinder W, control anode S and concentration anode A, a pair of auxiliary, constantly biassed plates H are arranged in front of each pair P<1>, P<2> of main plates. The plate of each main pair towards which the ray is deflected, by the auxiliary plates may be inclined as shown at P<1> and nearer to the ray than the other plate. One plate of each pair may be connected to the anode. The other plates of the pairs H may be connected together and to the cathode inside the tube. In a modification, the two pairs H of auxiliary plates are replaced by a single pair inclined to the main plates. The Specification as open to inspection under Sect. 91 comprises also a modification in which the auxiliary plates are omitted, the tube being constructed so that the axis of the electrode system points to a corner of the screen. This subject-matter does not appear in the Specification as accepted.
