    Abstract: Disclosed is an electric oscillation generator comprising an exciter and an output amplifier stage utilizing a vacuum tube connected in a common-grid circuit. A section of the input circuit of the vacuum tube is connected to the output of the exciter. The exciter is made as a power supply through a compensating-voltage producing device connected in series with said section of the input circuit and having an output voltage opposite in phase to the voltage across said section of the input circuit of the vacuum tube.

    Abstract: In a directly heated meshed cathode made of one metal piece in the form of a hollow cylinder, the working surface is constituted by intersecting helical filaments 3 and 4 with holes 5 therebetween, each filament 3 and 4 being formed with a stepped increase in the width from periphery to center of the cathode.A method of making the meshed cathode comprises fabrication of a tool electrode out of a plate by electroerosive cutting of grooves in the end portion of the plate with projections therebetween shaped to match the holes 5 between the filaments 3 and 4, and electroerosive broaching, using this tool electrode, of longitudinal rows of holes 5 in a hollow cylindrical blank rotatably displaced, after each pass of the tool electrode, through an angle equal to twice the angular distance between the center lines of adjacent longitudinal rows of holes 5 in the cathode. The grooves are cut out in the plate so that after each pass of the tool electrode, there are produced in the blank: full holes 5 of one longitudinal row, hole-halves 5' of two rows adjoining thereto, and corresponding sections of the filaments 3 and 4 between these holes 5.
