Abstract

657,093. Making grids for electron discharge tubes. RADIO CORPORATION OF AMERICA. Nov. 11, 1947, No. 30005. Convention date, Nov. 26, 1946. [Class 83 (ii)] [Also in Group XL (a)] The aligned grids of an electron tube (see Group XL (a)) are made by cutting the supporting rods 19 to length, holding between members 39, 40, Fig. 5, and swaging by members 36, 37 against anvils 41, 42 to form rectangular pro. jections and recesses. The rods are then mounted in a winding machine between aligned chucks 22, 23, Fig. 7, provided with a notch cutting wheel 26 and peening wheel 27 for closing the groove over the embedded grid wire. Either the chucks or the wheels are held stationary, the other part being rotated.
