Title: Apparatus incorporating an electrical isolating transformer
IPC: H05H5/02
Filed: 1969-03-19
Abstract: 1,256,011. Transformers; discharge apparatus. COMMISSARIAT A L'ENERGIE ATOMIQUE. 19 March, 1969 [20 March, 1968], No. 14438/69. Headings H1D and H1T. [Also in Division H2] Apparatus for the transmission of A.C. power from a first to a second circuit at different D.C. potentials includes an isolating transformer comprising an insulated conductor 10 passing through a magnetic core 19 which further carries a winding 20. As shown, the insulation 14 of the conductor 12 withstands a steady potential difference U between a power source 16 and a load 18 to which the cable 10 is coupled by another transformer 24. The winding 28 is maintained at a potential U with respect to earth and the winding 20 is fed by a D.C. source 29. To avoid voltage " creep " along the cable 10 the insulation 14 ends only at portions of the cable remote from the core 19. The voltage U at the cable ends depends on the ratio of the areas of cross-section of the cores 19 and 24 and the source voltage. Preferably this ratio is equal to the number of turns of winding 26, in order to keep the value of U a sufficiently large fraction of the source voltage. If the load requires only a low voltage it may be fed by a winding 10. In another embodiment the arrangement is reversed (Fig. 2, not shown). The load is supplied via a ferrite core (40) to which the cable is linked and the source is connected to the cable ends via a second transformer which may be fed through a frequency changer (36). The cable is maintained at the supply circuit potential. When the steady voltage U is more than a few kilo-volts the isolating transformer may be disposed in a gas such as sulphur hexafluoride at high pressure (Fig. 3, not shown). The isolating transformer may be used to supply power to a particle accelerator or to an X-ray tube. The transformer is enclosed by the metal container (46, Fig. 4, not shown) of the accelerator which constitutes a return path at one end of the insulated cable (12c).

Abstract: 1423240 Carbon fibre reinforced carbon bodies DUCOMMUN Inc 28 March 1973 [28 March 1972] 14798/73 Heading C1A [Also in Division C7] A fibre reinforced composite is produced by forming a substrate from a compressible fibrous carbon material, such that the volume of the initial substrate is greater than the volume of the final product, compressing the substrate by pressure compaction means such that the volume of the substrate is reduced and it is shaped substantially into its finally desired form, and then binding the fibrous mass, whilst it is constrained so as to maintain its shape and fibre volume, by pyrolytically depositing a pyrolytic material in the pores of the mass to act as a binder. The pyrolytic material may be pyrolytic carbon, pyrolytic graphite, silicon nitride, boron nitride, titanium, tantalum, tungsten, molybdenum, niobium, tantalum carbide, niobium carbide, zirconium carbide, hafnium carbide, tungsten carbide, titanium carbide, and silicon carbide. The substrate may be in the form of a woven material having a multiplicity of interwoven carbon fibres. The substrate may also comprise a plurality of layers of woven material lying in planes forming an angle relative to the longitudinal axis of the substrate. In alternative embodiments, the woven material can be wound circumferentially round the longitudinal axis of the substrate or it can be shaped as a series of hollow conical members which are nested together to form the substrate. The woven carbon material may also be laid as pieces having a desired shape arranged in shingle fashion to form a desired complete shape. The fibrous carbon material may have been derived from rayon, polyacrylonitrile, wool or pitch. Particular fibre volumes are given for the substrates. The impregnated substrate may be densified by a further stage of pyrolytic decomposition. Before being assembled into the compressible substrate the fibrous carbon material may be abraded so as to raise a nap on the material to provide an increased number of deposition sites. Random arrays of carbon fibres, and carbon felts may also be used as substrates. The examples are all directed to the deposition of pyrolytic carbon on the substrate using temperatures of 1875‹ to 1900‹ F. Properties, e.g. density, of the completed composites are given.
