Title: Fuel elements for nuclear reactors
IPC: G21C3/04
Filed: 1971-12-22
Abstract: 1372103 Fuel elements KERNFORSCHUNGSANLAGE JULICH GmbH 22 Dec 1971 [24 Oct 1970] 59707/71 Heading G6C A fuel element has a flow passage extending within it and passing through one or more fuel bodies located in the passage and comprising coated nuclear fuel particles and porous walls bounding the particles. Portions of the passage form supply and discharge zones for the coolant with respect to the or each body, each of the supply and discharge zones being so shaped that the longitudinal component of coolant velocity in the passage is substantially constant throughout the zone. As shown in Fig. 1, outer and inner coaxial cylindrical members 1, 2 define a passage between them in which there is a fuel body comprising a mass of coated fuel particles 3 between porous support members 4. The particles 3, coated with pyrolytic carbon or silicon carbide, may be present as a loose mass or be bound together to give a porous structure. The diameters of the particles are within the range 10<SP>2</SP> to 5 Î 10<SP>3</SP> microns. The fuel element has an inlet 5 at its lower end which together with inlet openings in the cylinder 1 serve for the entry of coolant. The coolant flows as shown by the arrows and leaves via outlet openings formed at the top of the cylinder 1. The porous support members 4 comprise either a solid porous lattice structure of coated fuel particles united with one another or perforated plates or screens of different material. Alternative forms of fuel body include double frusto-conical bodies and bodies in the form of corrugated members whose corrugations run horizontally. To allow for thermal expansion of the fuel particles, a layer of a resilient, flexible, porous material having a small neutron capture cross-section may be provided between the support members 4 and the fuel particles 3 and intermediate layers of a similar material may be incorporated within the mass of fuel particles 3. Suitable materials are felts and woven fabrics consisting of graphite or silica. The supply zone of the fuel body 3, 4, which can be considered as the space lying radially inwardly of the fuel body between it and the cylinder 2, progressively narrows in the axial flow direction in proportion as the coolant has passed through the body with the result that the axial component of flow velocity in the zone remains constant. The same applies to the progressively widening discharge zone lying radially outwardly of the fuel body 3, 4.

Patent GB-614277-A (GB)
Abstract: 614,277. Recording-apparatus. LAURENT, G. L. July 10, 1946, No. 20581. Convention date, Oct. 4, 1945. [Class 106 (iv)] Means for recording on a paper strip the duration of each successive time period in a sequence comprises two sliding gears for alternatively gearing driving means to time print wheels or to a printing control shaft which shaft also controls the sliding gears and the zeroizing of the time print wheels and feeding of the paper after each recording. A gear-wheel 2 engages a sliding gear 6 through a dog 4 and so drives a gear 9 which through gears 13, with aligning springs 14, drives time print wheels 8 which are carried loose on the shaft of the gear 9. To effect printing at the end of a time period a knob 16 is pressed as limited by a stop 44<1> so that a pawl 17 initiates rotation of a cam-shaft 21 through a cam 19, whereupon a cam 22 together with stops 23, 25 on a lever 24 causes a second sliding gear 7 to be driven by the gear-wheel 2 and so to drive the camshaft 21. In a similar way a cam 29 causes the first sliding gear 6 to disengage the gear-wheel 2. As the cam-shaft turns, a cam 26 raises a frame 27 in which the print wheels are mounted against a spring 28 and causes printing on a paper strip 10 which slides over a carrier plate secured to columns 15. An ink ribbon may be provided or the paper specially prepared. Thereafter, a cam 34 causes the spindle carrying the print wheels to rotate and through a longitudinal groove and catches on the wheels causes zeroizing. A cam 35 co-operates with a pawl 36 to feed the paper and the cam 29 releases the sliding gear 6, while the cam 22 disengages the sliding gear 7 so that the gear 2 drives the time wheels again. To prevent the time wheels from being driven after the final recording of a sequence, a knob 38 is pressed until a stop 44 engages a groove therein to arrest it when the stop 441 will rise clear of a shoulder on the knob 16 in preparation for restarting. Pressing the knob 38 advances the knob 16 to initiate the rotation of the camshaft 21 and cause printing, but a rod 42 locks a bar 41 to withhold the re-engagement of the sliding gear 6 with the driving gear 2 until it is desired to start a new sequence when the knob 16 is pressed further, allowing the stop 44 to release the knob 38 which withdraws and unlocks the bar 41.
