Title: Improvements in the manufacture of mixed carbides and of articles made therefrom
IPC: C22C1/05
Filed: 1936-09-10
Abstract: Hard alloys, particularly for tools and dies, consisting mainly of metal carbides, comprise at least two carbides embedded in a mass of mixed crystals which consist wholly or mainly of a solid solution of the same metal carbides in one another, the usual addition of iron group metal binder being wholly or substantially wholly dispensed with.  The carbides may be, for example, those of tungsten and titanium, or vanadium and titanium, or titanium and chromium, with or without the addition of a carbide of an iron group metal, and with or without up to 25 per cent of free titanium.  The alloys may be made, for example, by finely grinding and mixing together two or more metals or compounds thereof, for example oxides of titanium, tungsten, and vanadium, with carbon or a substance yielding carbon such as lamp black or calcium carbide, and heating the mixture to 1600-1800 DEG  C.; or a mixture of metallic tungsten, titanic acid, and carbon or a carbon-yielding body may be used.  The mixture may be heated directly to fusion and the product cast in carbon moulds, or it may be ground after being formed, and, with or without addition of an iron group carbide and a carbon-yielding substance such as calcium carbide, may be pressed and heated to 1300-1600 DEG  C.  The Specification as open to inspection under Sect. 91 refers also to the following further elements as constituents of the alloys: silicon, boron, tantalum, molybdenum, zirconium, uranium, nickel, cobalt.  It describes also coated or composite articles, such as nozzles, consisting of a core made of an alloy as above coated with a metal such as titanium, molybdenum, aluminium, an iron group metal, or an alloy of a metal of the iron group, such coating being applied by spraying or electrolysis, or by deposition from a compound such as a carbonyl; the coated article may be heated to ensure consolidation and impregnation.  This subject-matter does not appear in the Specification as accepted.  Reference has been directed by the Comptroller to Specifications 460,013 and 463,239.

Electric discharge device of the type comprising a cathode, a fluorescent anode and two deflecting members connectable each to a separate voltage source so that the fluorescent pattern on the anode indicates a voltage difference between the sources has the deflecting members 5, 6, Fig. 1, in the form of plates or vanes in the same plane substantially parallel to and on the same side of a rectilinear cathode 1, the deflecting members having adjacent faces parallel to and at a short distance from each other so as to form together an elongated structure with a gap or slot extending between its longer sides. The fluorescent anode 2 is planar and parallel to the cathode and is formed from a nickel plate having a coating 3 of zinc orthosilicate deposited thereon from a suspension of that material in alcohol. The cathode 1 is supported by conductors 16 from a shield member 4 which is positioned behind the cathode to direct the electron beam towards the anode. In the construction shown in Fig. 2 the shield is of angular cross-section with both sides inclined to the anode 2 and the deflecting members 5, 6 lie in the same plane as part of the shield. In the construction shown in Fig. 5, the deflecting members 5, 6 are parallel to the anode 21 which has an overhanging portion 20 to obscure the edge portion of the anode. The above constructions give a kinked line separation between the light and dark portions of the anode when different voltages are applied to the deflecting members 5, 6. In the construction shown in Fig. 7 the shield 4 is of T crosssection, and the deflecting members 23, 24 are separated by an inclined slot. This arrangement gives an inclined indication on the fluorescent anode 2 according to the difference in magnitude of the voltages impressed on the deflecting members 5, 6. Fig. 8 shows a construction in which the shield 25 is of box formation and in which a masking 27 having an elongated aperture 27<SP>1</SP> is supported at 26 from the anode 2. More than two deflecting members can be arranged so that groups of two deflecting members have adjacent edges or end faces to form gaps between them and are connected to separate voltage sources.
