Title: Process for the production of chlorides from oxides
Inventor: BAUER WILLIAM V
IPC: C01B35/06
Filed: 1959-02-09
Abstract: <PICT:0865939/III/1> A process for producing a chloride from an oxide comprises forming a fluidized bed containing carbon and an oxide, passing an electric current between spaced electrodes and through the solids in the bed, thereby heating the bed due to the electrical resistance of the carbon, and passing chlorine through the bed. An apparatus which may be used in carrying out the process comprises an outer layer of fire brick 7, an inner layer of hard refractory 8, a feed inlet 9 for solid materials, a gas inlet and outlet 14 and 12 respectively, and spaced graphite electrodes 16 and 17. Borontrichloride is produced by reacting boric oxide and chlorine in the presence of carbon in a slightly modified apparatus.  A further form of apparatus (Fig. 2, not shown) comprises a carbon or graphite electrode mounted axially in a carbon or graphite cylinder forming the other electrode and provided with a gas inlet and outlet and an arrangement for feeding solids to the cylinder.  This apparatus may be used to chlorinate a metal oxide to produce a metal chloride. ZrCl4 and SiCl4 are produced by feeding a mixture of milled zircon and calcined coke into a chlorine gas stream which is fed into a bed of calcined petroleum coke fluidized with nitrogen.  Aluminium chloride is produced by feeding a mixture of aluminium oxide and coke to the chlorine gas.  Silicon tetrachloride is produced by feeding a mixture of silica and coke to the gas.  Modified forms of the apparatus are used to carry out the following reactions. ZrCl4 and SiCl4 are produced by feeding a mixture of granular zircon and calcined coke to a point below the surface of the fluidized bed, the chlorine being fed in separately. TiCl4 is produced by feeding a mixture of rutile and coke to a point above the surface of a bed of calcined coke fluidized with nitrogen which is later replaced by chlorine.  BCl3 is produced by using a mixture of boron oxide and coke. NbOCl3, TaCl5 and other chlorides, e.g. NbCl5, are produced by chlorination of a niobium ore by two processes, in one of which gases from a first reaction are used to fluidize a second bed.  VCl4 is produced from commercial oven dried V2O5 consisting of approximately 95% V2O5 and 5% Na2O present as sodium metavanadate.

Title: Improvements in the production of gas-turbine blades containing voids
Inventor: PFEIL LEONARD BESSEMER
IPC: B23P15/02
Filed: 1953-02-19
Abstract: 745,655. Extruding. WIGGIN & CO., Ltd., H. May 19, 1954 [Feb. 19, 1953], No. 4709/53. Classes 83 (2) and 83 (4). In the manufacture of a chromium alloy gas turbine blade containing voids, for example for use as cooling passages, a number of bars or the like of the alloy are each provided with an impermeable coating of a metal or alloy having low affinity for oxygen, the bars are assembled together side by side, with filler material extending longitudinally between or through the bars, the assembly is then extruded through an orifice to form it into a composite billet whereby the spaces occupied by the filler are elongated and the filler is subsequently removed to form the voids. The bars are preferably of chromium-cobalt-nickel alloy containing small quantities of titanium and aluminium and are coated with cobalt, copper, iron or preferably nickel which is applied by electrodeposition. The filler may be in bar form or the alloy bars when nested together may leave gaps for the filler. Alternatively the alloy bars may have longitudinal holes occupied by filler. The assembly may be consolidated before extrusion and for the extrusion step is preferably put into a case of nickel or nickel-chromium alloy sheet the ends of which may be sealed by spraying with nickel after insertion of the assembly. The case becomes part of the extruded blade. Glass may be used as a lubricant during extrusion. The filler, if of low melting point metal, is subsequently removed by melting, or other metal fillers may be disintegrated by inducing inter-granular corrosion and then blowing it out or it may be dissolved by an acid which will not affect the chromium-alloy. If the filler is of molybdenum or graphite it may be removed by oxidation and if of a refractory material it may be disintegrated during subsequent hot working operations on the billet and thereafter removed by jets of water or air. At the leading and trailing ends of the extruded billet the holes may be distorted and these ends may have to be scrapped, therefore one or both of these ends may be of a cheaper material shaped to fit the extrusion container. In the manufacture of a tubular product with voids in its walls, the assembly may be provided with a central core of filler material in addition to that forming the voids; alternatively the core may be of metal which is prevented, by an oxide surface layer or otherwise, from welding to the surrounding alloy bars during the extrusion. If the finished product has to have a large number of voids, the extruded billet may be cut into bars which are nested to gether to form a second assembly which is again extruded.
