Abstract: 242,951. Gewerkschaft Wallram. Nov. 14, 1924, [Convention date]. Addition to 239,499, [Class 1 (ii), Inorganic compounds, other than &c.]. Processes.-Materials to be fused are introduced into a crucible formed by a cavity 28, Fig. 1, in a carbon rod 27 which is inserted into a carbon tube 18 forming the heating element of an electric' furnace. A check block 29 pressed from the material to be melted is placed loosely on the material in the cavity. The rod 27 is wedge-shaped to allow observation by an optical pyrometer 30 of the check block. The rod 27 is left in the furnace for an empirically determined period after melting has been observed to begin, and is then removed with asbestos gloves and emptied into a casting mould outside the furnace. The carbon tube 18 is mounted between carbon or graphite terminal blocks 19 mounted in a sheetiron container 22 filled with an incombustible non-conducting loose mass such as carbon granules. The container is provided with a detachable cover 23 and a valve 24 in the bottom by means of which the contents may be emptied into a lower container 25 when it is desired to replace a consumed resistance tube. Hydrogen, ammonia, or other neutral gas may be admitted by a pipe 26. In a crucible for large castings, the cavity 32, Fig. 2, is connected by a channel 34 having a slight gradient to an outlet 35 situated above the funnel 36 of a mould 37. The outlet :35 may be closed for a predeterminel period after melting has begun. The mould 37 may be at first heated and afterwards cooled in such a way as to control the crystalline form and texture of the product. The proooss and apparatus are particularly applicable to the production of tungsten and other ueavy metal carbides. The charge may consist of highly reduced metallic tungsten mixed with powdered carbon. Absorption of carbon may take place from the melting crucible or by evaporation from the walls of the furnace. The period during which the crucibles is left after melting has been observed to start should be chosen so as to preclude excessive absorption of carbon as the resulting compound could not then be cast. Powdered molybdenum, titanium, uranium, chromium, and vanadium, either alone or with powdered carbon or carbide, may be treated instead of tungsten. Silicon and boron may be also treated for the production of carbides. Catalytic agents may be added to the charge. According to the Specification as open to inspection under Sect. 91 (3) (a) carbides or oxides of the metals may be used as raw materials. This subject-matter does not appear in the Specification as accepted.
