Title: Production of ingots or castings of refractory metals
IPC: B22D11/14
Filed: 1949-08-23
Abstract: 665,716. Producing titanium and zirconium. BATTELLE MEMORIAL INSTITUTE. Aug. 23, 1949 [Nov. 23, 1948], No. 21887/49. Class 82(i) A method of producing ingots or castings of the refractory metals titanium and zirconium, which refractory metal has been produced by reaction between a reducing metal and a halide of the refractory metal salt associated therewith, including the steps of introducing the refractory metal and contaminants into a chamber which contains a protective atmosphere, heating the refractory metal to a temperature at which it melts and at which the contaminants rise as a mist, cooling the refractory metal to the solid state and in which method the mist is collected in the protective atmosphere which is passed through the chamber under pressure, the mist being removed from the atmosphere outside the chamber and the purged atmosphere being re-circulated through the chamber. In the apparatus shown contaminated metal is introduced into chamber 21 from container 30 by feed screw 31. Heat sufficient to melt the refractory metal is produced by an arc between electrode 37 and the refractory metal ingot 41 which is continuously produced in the chamber. The walls of the chamber are cooled by two jackets, in which cooling media are circulated, namely 18, adjacent the lower part of the chamber in which the ingot is formed, and 17, adjacent the upper part of the chamber causing condensation on the walls of part of the mist which collects in the ring 49 and is removed through conduit 50 to the vessel 57. The remainder of the mist is removed by a circulating protective atmosphere which enters the chamber by conduit 45 through the electrode tip 37 and leaves the chamber by conduit 46. The gas containing the mist enters a scrubber 63 set in a furnace 64. The scrubber is heated, by combustion products entering the furnace at 65 and leaving at 66, to a temperature above the melting point of the constituents of the mist. The gas entering the scrubber follows a tortuous path between baffles 71 and deposits the reducing metal and reducing metal salt in molten form to be removed through valve 73. The stripped gas is recirculated by blower 69 to the chamber. Specification 665,715 is referred to.

Abstract: 874,094. Rolling tubes. PHOENIX-RHEINROHR AKTIENGESELLSCHAFT VEREINIGTE HUTTEN - UND ROHRENWERKE. July 9, 1958 [July 9, 1957], No. 22077/58. Class 83 (4). In a method of reducing the bore of a thickwalled pipe by passing it in an axial directon between skew rolls, the pipe and a cylindrical mandrel mounted within and in fixed relationship to the end are advanced to a position between the rolls at which an internal flange is formed at the end of the pipe to provide an abutment by which the pipe may be subsequently pushed into the roll pass so as to be moved axially over the mandrel to produce a uniform extension of the remaining part of the pipe. The rear end of the pipe bears against an abutment d (not shown) so fixed on the mandrel that the end face f of the inner mandrel e is situated before rolling at a desired distance behind the end of the pipe. As the mandrel is advanced the end of the pipe b impinges against the rolls a and the end portion i is deformed to a flange shape. For processing pipes of varying length the pipe b and the internal mandrel e are each moved by separate pushing-in devices against an arresting device t which is then removed and the two pushing-in devices are coupled to advance the pipe and mandrel between the rolls a. In another form, Fig. 5, a pipe bl is closed at one end by a thin end-plate w which limits the relative movement of the mandrel end stud q.

Title: Process for suppressing side reactions in the oxidation of hydrocarbons
IPC: C07C45/34
Filed: 1963-06-04
Abstract: Side reactions are suppressed in a product stream produced by partially oxidizing hydrocarbons having 1-8 carbon atoms by flowing a vapour phase mixture of the hydrocarbons and oxygen through a reaction zone wherein the reaction temperature is controlled, partially oxidizing the hydrocarbons within the reaction zone, discharging the resulting product stream containing oxidized hydrocarbons and residual oxygen from the reaction zone and cooling and condensing the oxidized hydrocarbons. The reaction product stream being flowed, prior to the condensation, through a mass of solid, extended-surface material which has a surface-to-volume ratio in excess of 31.5 m2 per m3 and a free volume in excess of 70%.  The extended surface may be provided by a multitude of small, tortuous passages formed by a solid material providing a high surface-to-volume ratio as well as a high free volume.  The "free volume" is the percentage of the bulk volume of the solid mass which is occupied by the passages.  Suitable extended surface materials are, e.g. a mat or mass of fine strands or wire which may be regularly or randomly oriented, consisting of stainless steel, carbon steel, copper, metal alloys, fused alumina, silicon carbide or ceramics. An example is given of the oxidation of propylene to acrolein.  It is stated that the process is applicable to the oxidation of aliphatic, alicyclic and aromatic hydrocarbons, e.g. the oxidation of methane to methanol and the oxidation of xylene to phthalic acid.  Suitable apparatus for carrying out the process is described.
