Text Appearing Before Image:
so hard that it cannotbe machined by sharp edge tools, but has tobe brought into desired shapes by high tem-perature hammering or cold grinding. The rough anode head for the Universal 256 Manufacture of the Coolid£:e A-Rav Tube tube is formed from a sintered tungsten rodin a swaging machine, which is a nicely con-trolled high speed hammer used in this caseto reduce. ))y successive operations, the diam-eter of the tungsten rod. The rod is heatedto about i6oo°C. in an atmosphere ofhydrogen gas in an electric furnace, and isthen rapidly passed through the swagingmachine. In this operation the diameter ofthe rod is reduced lo per cent. The rod is iiicnfs.—The tungsten wire used in makingthe filament for the cathode is produced ina similar manner, the rod being reduced insize ill the swaging machine until it may behot drawn to the required size of wirethrough diamond dies. MoLYHDEXUM.—\\rought molybdenumis ver\ much like wrought tungsten, butdiffers from it in that it can be machined

Fig. 2. Mold .\ni) Hydraulic Press for M.akixgRods from Tungsten and Molybdenum Powder.The operator is removing a rod from the moldafter pressing in the hydrauHc press at the right. then re-heated in the furnace and is readyfor the next pair of swaging dies, whichwill again reduce its diameter by lo per cent.When the rod is at the recjuired diameter forthe head of the anode, the end of the rodonly is swaged down to form the taper andstraight portion to which the molybdenumstem is attached. After rough grinding toapproximate size and shape, the anode headand molybdenum stem are swaged together.The assembly is completed by the additionof an iron collar and a thin metal tube andthe finished anode is then polished and verycarefully cleaned.
