Title: Process for coating particles and products resulting therefrom
IPC: C01B31/00
Filed: 1969-03-18
Abstract: 1,256,101. Fuel elements. GULF OIL CORP. 18 March, 1969 [28 March, 1968], No. 14045/69. Heading G6C. Nuclear fuel particles comprise cores 11 of fissile or fertile material each surrounded by a layer 13 of relatively low density pyrolytic carbon a seal layer 19 of impermeable pyrolytic carbon of sufficient thickness to provide a gas barrier, a layer 15 of dense SiC or ZrC, and a layer 17 of dense isotropic pyrolytic carbon. Materials specified for the cores 11 include (ThU)C 2  having Th : U mole ratio of 3 :1, and UC 2  and VO 2  having a U-235 enrichment of 93%. The layer 13 is preferably of spongy carbon having a density less than 60% of the theoretical maximum and serves both to accommodate expansion of the core 11 during high temperature operation and to absorb fission products. The presence of the seal layer 19 allows the particles to be transferred from one coating apparatus to another in the air without any problems of hydrolysis. Where the dense isotropic pyrolytic carbon of the layer 17 is to be deposited at temperatures within the range 1800 to 2000 C., there is a tendency for uranium to migrate from the core 11 into the layer 13 and in order to prevent this an additional seal layer may be provided between the core 11 and the layer 13. The seal layers are preferably of a dense laminar pyrolytic carbon. The layer 15 of SiC or ZrC serves to contain the fission products and to provide a layer having adequate strength to permit handling without risk of damage. SiC is commonly deposited by the pyrolysis of methyltrichlorosilane in the presence of an excess of H 2  gas. A by-product is HCl gas which is prevented from leaching U from the core by the seal layer 19. The dense isotropic pyrolytic carbon layer 17 which surrounds the carbide layer 15 shrinks under neutron irradiation, thus providing a compressive force on the layer 15 which counteracts the internal forces resulting from the build-up of gaseous fission products. In one example (Fig. 4, not shown) the dense isotropic carbon is in two layers, a layer interior of and a layer exterior of the carbide layer 15. The inner layer prevents possible chemical reaction between the material in the core 11 and the metal carbide, the effectiveness of the seal layers being destroyed during the expected life of the fuel particle.

The detachable coupling comprises a worm 1 positively driven by the motor 42 and engaging a worm wheel 2 loose on a main shaft 4 on which is fixed a boss 3 provided with a spring-biased coupling pin 6 which, when a tapered slot therein is not engaged by a disc 8, engages a recess in the worm wheel 2. The disc 8 is disengaged from the coupling pin 6 when the knife treadle 7 is depressed. The guillotine knife 9 is driven from the main shaft 4 through cranks 5, connecting rods 11 and pivoted cranks 10. The clamp 20 may be operated in synchronism with the operation of the guillotine knife by means of an eccentric 21, Fig. 2, on the main shaft 4 engaging one arm 22a of a bell-crank lever the other arm 22 of which moves a collar 32 and with it a shaft 16 to which the clamp 20 is coupled by means of cranks 19 and connecting rods 17. The pressure of the clamp may be adjusted by means of a crank 34. The clamp may, however, be actuated by means of a treadle 18 which when depressed actuates the clamp, by means of the shaft 16, cranks 19 and connecting rods 17. The treadle 18 is locked releasably in its depressed position by means of a spring- influenced lever 24 and is released after a certain rotation of an eccentric 30 on the main shaft 4 operating a bell-crank lever 28 engaging the lever 24. The lever 24 has an extension 24a forming a subsidiary clamp treadle which is adapted to engage the shaft 16 to drive the connecting rods 17 independently of any automatic operating means. To allow of measurement of the material to be cut, the clamp 20 has a sawtoothed edge, the material is illuminated by means of a fluorescent lamp 39, Fig. 3, and a straight edge rule device is provided which comprises a graduated endless belt 53 adapted to be driven by means of a toothed rack 46 one end of which is connected to a straight edge 52, the rack being driven by a hand wheel 49. The straight edge is provided with retractable pins for supporting thin sheets of material to be cut.

Abstract: 934,098. Locating faults in cables and pipelines; voltage measurement; measuring bridges; fault testing. BRITISH INSULATED CALLENDER'S CONSTRUCTION CO. Ltd. April 28, 1960 [April 28, 1959], No. 14546/59. Class 37. A method of detecting perforations in the insulating outer covering of an underground cable or pipe comprises feeding a direct current, interrupted at a very low frequency, to the cable or pipe and traversing the surface of the ground along the route with a pair of probes connected to a voltmeter. In Fig. 5, a pulsating direct current is fed from source 40 to an underground pipe 42 having an insulating outer covering 43. A perforation such as 45 in the outer covering 43 will result in a potential gradient occurring along the surface of the ground. This is detected by a voltmeter 44 carried by a man, represented by resistance 46 walking along the route. The man 46 must not wear highly insulating footwear and holds one terminal of the voltmeter 44; the other terminal being carried by a second man representated at 47. The pulsation of the supply current may be coded and is of a sufficiently low frequency to cause a visible variation in the voltmeter reading. A null is detected when the two men are equidistant from the fault 45. Alternatively, the men 46, 47 may use extended probes contacting the surface of the ground. Fig. 1 (not shown) relates to a constant-current power supply unit, the output of which is pulsated by means of mechanically controlled contacts. Portable valve voltmeters.-Fig. 4 shows a valve voltmeter suitable for use at 44 and comprising a bridge circuit formed by a pair of valves 30 and the two halves of a potentiometer 31. The bridge is initially balanced by adjustment of potentiometer 31 so as to give zero indication on the centre-zero microammeter 39. The bridge becomes unbalanced by a D.C. potential present between the manually-held probes 25 so that the deflection of instrument 39 is dependent on the value of the applied potential. The potentiometer 31 may be adjusted so that the pointer of instrument 39 remains on the scale despite the presence of extraneous unmodulated potentials between the probes 25. The instrument sensitivity may be changed by one operator holding part 27 of his probe so that a series resistor 29 is incorporated.
