Abstract

655,308. Thermionic valves. PHILIPS ELECTRICAL, Ltd. Oct. 30, 1947, No. 29029. Convention date, Nov. 2, 1946. [Class 39 (i)] An electric discharge tube having at least a cathode 5, control grid 6, a screen grid 7, and an anode 8, in which the electrons are concentrated into one or more beams the width of which varies with the voltage of the control grid, has the screen grid connected to members 9 which are designed to intercept part of the anode current so that the anode current/grid voltage characteristic is more linear than a <SP>3</SP>/ 2 power curve. The spacing of the members 9 is preferably arranged so that half their width is located within the beam at the working point of the tube and may be arranged so that they lie wholly within or wholly outside the beam or beams towards one end of the working range. The members may be in the form of rods which may be bent at one or more points and the rods may serve as support rods for the screen grid. Alternatively the members may be in the form of strips which may be of trapezoidal shape or may be notched or recessed at their edges. Specification 467,573 is referred to.
