Title: Nuclear reactor fuel pins
IPC: G21C3/16
Filed: 1970-06-17
Abstract: 1314248 Fuel elements UNITED KINGDOM ATOMIC ENERGY AUTHORITY 26 May 1971 [17 June 1970] 29450/70 Heading G6C A fuel pin for use in a high temperature gascooled reactor comprises a stack of fuel compacts 1 (comprising coated uranium oxide particles dispersed in a graphite matrix) enclosed in an annular chamber 2 bonded by two coaxial graphite tubes 3, 4. The tubes are rigidly secured together at one end by a screw thre ad 5 sealably to close the end of the chamber. The outer tube 4 has a radially inwardly projecting flange 6 secured by a screw thread 7, the flange presenting a sliding surface 8 to the inner tube 3 and closing the other end of the chamber. A clearance space 9 is provided to accommodate longitudinal dimensional changes in the fuel compacts and graphite tubes. The outer tube 4 has three equally spaced, longitudinal ribs 10 which resist bowing of the fuel pin and also serve to locate it centrally within a fuel channel. The annular chamber 2 may alternatively be formed by trepanning a single bore of graphite. Under irradiation, the compacts 1 shrink radially on to the inner tube 3 and grow longitudinally so that, when they have shrunk sufficiently to grip the inner tube, a tensile strain is induced in the tubes over most of its length by further longitudinal growth. Thi s growth is also reacted by the outer tube 4 by reason of the abutment of the stack of compacts 1 with the flange 6 and the rigid junction of the sealed end closure so that the strain due to growth is significantly less than in the case where compact growth is resisted only by the inner tube. The reactor core comprises stacked prismatic blocks of graphite having bores which co-operate to form vertical channels each of which houses a stack of fuel pins. Coolant flow (helium) is downwardly through the channels, and over and through the tubular fuel pins. A pressure drop is created over the fuel pins but because the uppermost ends of the fuel pins are sealed any coolant entering the fuel pins will permeate through the tubes and any oxidants in the helium will react with the graphite before they reach the fuel.

Abstract: 1333370 Machine for hand-wrapping articles FELRAP Inc 31 May 1972 25411/72 Heading B8C A packing machine 10 for use in hand-wrapping articles in a flexible heat sealable sheet material comprises a supporting frame 11 with a fixed wrapping platform 12, a heat sealing tray 28 having a heated surface and mounted for movement between operative and inoperative positions respectively forward of, and underneath, the platform 12, and support means 18 for a supply roll 19 of the heat-sealable sheet material. Plates 45, 46, pivoted respectively in bearing members 50, 51 secured to the frame 11, carry a heated severing wire 26 and a trip blade 48 for manually rocking the wire 26 against a counterbalancing bias, above the level of the platform 12. The tray 28, covered for example with polytetrafluoroethylene, is fixed to a carriage 30 which has, along each side, a pair of spacers 31, 32 which define a track for a pair of rollers 34 mounted on the inside of a corresponding frame member 40. The carriage 30 is mounted on an inclined plane containing the axes of the rollers 34 so that it is biased by gravity for sliding movement into its normal forward heat-sealing and operative position. Spacers 36 compensate for the angle of incline so that the tray 28 is maintained parallel with the platform 12. Electricity is fed through an on-off  switch 29 to the heating wire 26 and through a thermostat 27 to the tray 28. In use the desired length of film is pulled, by an operator, from the roll 19, over guide bars 20 and through a slot 21 adjacent the forward edge of the platform 12 and a first tight band is made around a laundry bundle 60, the operator simultaneously exerting pressure against a safety bar 35 carried by the tray 28 to hold the latter in its inoperative position beneath the platform 12. The operator then steps back and the tray 28 slides out to its operative, forward, position as the operator picks up the bundle 60 from the platform 12 and draws the film over the trip blade 48 so that the exposed heated wire 26 severs the film as the package is placed on the tray 28 for a first seal. The operator then folds the ends of the film under the package before placing the latter down again on to the tray 28 to form the final seals. In a modification, Figs. 9, 9A, not shown, two rolls 19 of film are rotatably supported upon spaced parallel rollers (61). Two films from separate rolls (19) each pass around a pair of guide bars (20, 20) and through a respective pair of guide rollers (62) adjacent the slot (21). A pivotally mounted selector flap (63) can be positioned to obstruct one film feed while freeing the other to the operator.

Filed: 1970-06-19
Abstract: 1354114 Colour television RCA CORPORATION 15 June 1971 [19 June 1970] 29969/70 Heading H4F A colour television receiver receiving PAL signals with swinging colour bursts comprises a colour killer 24 operative to prevent colour reproduction if bursts are not present or if a flip-flop 15 controlling PAL switch 9 is out of phase with the received swinging bursts. The flip-flop 15 is controlled by a trigger source 13 receiving the line sync. pulses and antiphase outputs from flip-flop 15 are fed on lines 16, 20 to a synchronous demodulator 19 to which is also fed a square wave signal from phase control 11 which is in phase with the signal from oscillator 8 phase-locked by loop 12 with the average phase of the incoming bursts. If the inputs to demodulator 19 indicate antiphase operation a positive signal results at 21, colour killer 24 is operated and inhibitor 22 stops flip-flop 15. If no signal is present at input 16 or 18 (as when flip-flop has been cut-off or colour bursts are absent) a zero signal is produced at 21 which operates colour killer 24 but not inhibitor 22 which allows flip-flop 15 to be restarted by source 13. With inputs to demodulator 19 indicating in phase operation a negative output at 21 does not operate killer 24 or inhibitor 22. A delay may be provided so that colour killing is initiated only if a number of consecutive bursts are missing. In a receiver for operation with a SECAM (R.T.M.) signal having different subcarrier rest frequencies on alternate lines the square wave signal at 18 is obtained using a gated discriminator and an integrator.
