Title: Improvements in or relating to methods of producing carbonimpregnated artefacts
Inventor: CARLEY-MACAULY KENNETH WALLACE
IPC: C01B31/00
Filed: 1960-04-26
Abstract: A carbon-impregnated artefact is produced by arranging an artefact of open porosity at least 60% of its volume and low thermal conductivity in an atmosphere of hydrocarbon gas which permeates the artefact, heating an initial zone of the artefact to a temperature at which carbon is deposited from said hydrocarbon gas to impregnate substantially fully the initial zone with carbon, and then raising the temperature of the impregnated zone so as to maintain the deposition temperature within an advancing impregnated/non-impregnated boundary, the rate of rise of temperature in the initial zone being limited so that the zone defined by the advancing boundary is substantially fully impregnated with carbon. The artefact may be a carbon mass, e.g. a mass of carbon black particles or a carbonized cellulose fibrous material such as cotton wool, cotton, rayon, and cardboard, a mixture of carbon particles and a nuclear fuel material, which may be precoated with carbon, or a carbonized cellulose fibrous material having incorporated therein a nuclear fuel material.  Both the mass of carbon and the mixtures of carbon with nuclear fuel material may be first compacted into coherent masses and granulated.  The artefact may also be silica or alumina in which case the corresponding carbides may be formed, and the nuclear fuel material may also give rise to carbides.  When the artefact has two opposed surfaces, the first of these surfaces is heated while hydrocarbon gas is supplied to the second surface, and as the temperature of the first surface is gradually raised the zone of deposition of carbon moves from the first surface towards the second surface.  The artefact may be in the form of a tube, the inner surface of which may be heated, e.g. by a graphite heating element passing concentrically therethrough, either in contact or not with the inner surface of the tube, while the hydrocarbon gas is supplied to the outer surface, which may be cooled artificially.  If the heating element is not in contact with the tube an inert gas, e.g. argon, may be passed through the annular space between the tube and the element.  Alternatively the outer surface of the tube may be heated, hydrocarbon gas being supplied to the inner surface, in which case the inner surface may be cooled by a cooling fluid passing through a concentric inner tube.  Suitable hydrocarbons are methane, which may be diluted with hydrogen, ethane, propane, butane, ethylene, propylene, butylene, benzene, and toluene.  Specification 878,927 is referred to.

[Class 39 (i)] In an electron tube with two anodes lying in the same primary electron circuit and connected in parallel with the same current source, the electrode system is divided symmetrically into two halves, each containing a grid G1 or G2, Fig. 1, and each anode A1 or A2 comprises a perforated part located in the other half of the electrode system between the cathode K and the grid G1 or G2. When the tube serves as a transmitter of very short waves, the capacity between one anode Al and its associated grid G1 is preferably greater than the capacity between the anode A2 and associated grid G2, to provide feed-back. Between the cathode and the perforated parts of the anodes there may be provided a grid G4, Fig. 2, for modulating the oscillations produced, a grid G3 for accelerating the electrons and a suppressor grid G5. The tube may be operated as a mixer. The tube of Fig. 1 may be used as an amplifier for D.C. or for low-frequency A.C. The Specification as open to inspection under Sect. 91 comprises also an electron tube in which the current distribution over two anodes A1, A2, Fig. 1b (Cancelled), is controlled by the cylindrical grid G, so that the current characteristics of the two anodes show transconductances of opposite sign. A rod-shaped deflector electrode AE fixed to the annular cathode K ensures that a sufficiently large part of the primary electrons reach the anode A1. This subject-matter does not appear in the Specification as accepted.
