Title: Nuclear reactor fuel elements
Inventor: ROBERTSON JAMES MARTIN
IPC: G21C3/36
Filed: 1964-03-20
Abstract: 1,095,652. Fuel elements. UNITED KING- DOM ATOMIC ENERGY AUTHORITY. Feb. 25, 1965 [March 20, 1964], No. 11970/64. Heading G6C. A fuel element of tubular form comprises a helically wound strip of protectively clad fuel material, adjacent edges of the wound strip being arranged in abutting edge to edge relationship and being joined together so as to form a tube with a helical seam. In the embodiment illustrated, a two-tube fuel element is formed by first winding a length of ribbed strip stock consisting of fuel material 4, such as natural or enriched uranium alloyed with aluminium, completely enclosed by protective cladding material 5, such as aluminium, upon a mandrel of circular cross-section in such a manner that adjacent edges are in abutting relationship, these edges then being joined together as for example by welding, brazing or interlocking engagement to form a tube 1 with a helical seam 2. An upstanding spacer rib 3 extends along one side of the strip stock adjacent that portion of the cladding material 5 which lies beyond the fuel material 4. A second length of ribbed strip stock is similarly wound and joined along its adjacent edges, the mandrel used being of increased diameter so that the inner diameter of the resulting tube 6 is equal to the outer diameter of the rib 3 on the tube 1. The width of the second strip is increased compared with that of the first strip so that both strips have the same pitch at their different diameters. The tube 6 has fuel material 9 enclosed in cladding material 10, and its seam 7 and rib 8 lie in positions corresponding to the seam 2 and rib 3 of the tube 1 when the two tubes are assembled as shown. The outer face of the rib 3 may be coated with brazing material so that on heating the assembly the rib 3 is bonded to the inner surface of the tube 6. A plurality of tubes can be built up and assembled in this manner in order to form a fuel element of multi-layer construction. A channel 11 is defined by the rib 3 between the tubes 1, 6 for the flow of coolant lengthwise along the element when installed in a nuclear reactor. The opposing faces of each tube 1, 6 may be roughened as for example by knurling to increase heat transfer. A single tube fuel element may be formed without a spacer rib and in the two-tube element illustrated, the rib 8 may be omitted.

Title: Improvements in or relating to circuits for generating electrical impulses
IPC: H04N5/06
Filed: 1946-04-20
Abstract: 611,751. Television. WHITE, E. L. C., and NEWMAN, E. A. April 20, 1946, No. 12145. [Class 40 (iii)] [Also in Group XL (c)] A circuit for generating impulses commencing with one of a sequence of impulses under the control of switching impulses, comprises a trigger pair of valves, means for applying the impulse sequence to both valves and the switching impulse to at least one valve, so that on appearance of a switching impulse the valves are conditioned so that one of the impulse sequence causes the valves to change from one stable state to the other. Fig. 1 shows an application to television, positive double-line frequency pulses are applied to terminal 11 and negative frame switching pulses to terminal 10. Initially valve 21 is conducting and double-line pulses appear at grid 25 via resistor 16 as shown at 40, Fig. 3, and due to amplification in valve 21 appear at grid 24 as shown at 50, Fig. 2. At point 41, Fig. 3, a negative frame switching pulse initiates the generation of the required frame keying pulse, the low-pass filter 12, 13 causes the potential of grid 25 to fall, Fig. 3, and that of grid 24 to rise until at instant 54, Fig. 2, when impulse 53 terminates, grid 24 rises above cut-off and the trigger pair changes over to the other of its two stable states. Double line pulses at grid 24 are amplified and appear at grid 25 as at 45, Fig. 3, this portion rising by virtue of the short time constant of the resistor-capacitor combination 14, 15. At point 46, Fig. 3, pulse 47 terminates, grid 25 is driven above cut-off and the trigger pair reverts to its original state; a square frame keying pulse thus appearing at the anode of valve 21, the duration being adjustable by resistor 15. In a modification, Fig. 4 (not shown), the trigger pair is comprised by cross-connected triodes having a common cathode impedance, negative double-line frequency pulses are fed to the common cathode circuit and positive frame switching pulses to one anode circuit, the waveforms developed at the grid and cathode circuits appearing as in Fig. 5 (not shown). The time constants of both grid circuits are such that the duration of the frame synchronizing pulse is coarsely determined by the duration of the frame switching pulse, and in a further modification the duration of the frame synchronizing pulse is coarsely determined by the time constants of the valve grid circuits. In a modification, Fig. 6 (not shown), one cross-coupling of the trigger pair is omitted, the negative frame synchronizing pulses are applied to one grid circuit via a low-pass filter and negative double-line pulses are amplified and outputs taken from the anode and cathode circuit of the amplifying stage to the anode of one valve of the trigger pair and to the common cathode circuit respectively, the duration of the frame keying pulse being set coarsely by the time constant of the grid circuit of one valve of the trigger pair.

Title: Improvements in and relating to the manufacture of cellular structures
Inventor: VICKERY JOHN PERCY
IPC: F04F13/00
Filed: 1958-04-17
Abstract: 862,595. Making pressure-exchangers. POWER JETS (RESEARCH & DEVELOPMENT) Ltd. April 7, 1959 [April 17, 1958], No. 12203/58. Class 83 (2). In making a cellular structure having inner and outer cylindrical members 1, 2 and walls 3 extending between the members, the walls are secured along one edge to the inner member 1 and along their opposite edges are located in slots 4 in the outer member 2 and secured therein along substantially the whole length of the slots from the outside of member 2. As applied to making the rotor of a pressureexchanger having radial or curved walls 3, these are each secured in the outer slot or slots 4 and in an inner groove in the member 1 by welding, brazing or furnace brazing. Alternatively, slots 4 may also be provided in member 1 for each wall or alternate walls. The member 1 is assembled on a mandrel 9 between sleeves 13 and discs 10 which locate rings 15 having radial grooves to receive the walls 3, which are then welded &c. to member 1. The assembled members are removed and may be stressrelieved before being remounted on the mandrel without sleeves 13 and the clamping nuts 19. Bolts 11 clamp the assembly while the outer edges of the walls 3 are ground. The bolts are then replaced by the sleeves 13 and nuts 19, and the assembly located in the outer member 2, which has axial grooves 8 to receive the walls 3 and form the inner parts of the slots 4. The walls are then welded to member 2 and may be cooled by the passage of air through openings 14 in the discs 10. Rods 18 in castellations in the discs and rings 10, 15 prevent distortion during welding. Disassembly from the mandrel and discs follows before the exchanger is heattreated, machined on the outer surface and the unslotted parts 6 are removed.

Abstract: 377,687. Tractor-trailer couplings. JACKSON, G. H., 6, Chase Hill, Enfield, Middlesex. April 27, 1931, No. 12388. [Class 79 (iii).] The front wheel or wheels 3 of a trailer 2 adapted to be coupled to a tractor 1 are carried by arms 8 swung from a. diametrical shaft 7 on the turntable 4, and normally secured in operative position by pivoted bars 9 formed with steps or notches 10 which engage pins 11, or a transverse rod connecting the arms, to hold them in the forward position, limited by slotted links 14. When, in coupling the vehicles, rollers 6 on the shaft 7 ride up inclined rails 19 on the tractor, the ends 9b of the bars 9 engage the rear axle 12, or cam-shaped plates 13 thereon and the arms 8 are released, being swung backwards by engagement of the wheels 3 with the axle. In order to ensure positive return of the wheels to operative position upon uncoupling, horns 17, Fig. 4, are attached to the arms 8 and drop over the axle as the arms are tilted, being raised by engagement with the axle as the tractor is withdrawn. In coupling the vehicles, the rollers 6, upon riding up the rails 19, press down hooked catches 22a and are engaged thereby on reaching stops 21. The catches 22a, which are mounted on pivots 24, may be released against springs 23 by operation of a lever 25 from the driver's seat. Brakes on the trailer may be operated by a lever 20 through a cable 28 which, when required, may be connected directly to a cable 30 for operation by the driver on the tractor. The restraining action of the links 14 may be assisted by stops or abutments (not shown).

Filed: 1953-05-06
Abstract: 748,897. Reservoir pens. MENTMORE MANUFACTURING CO., Ltd. May 6, 1954 [May 6, 1953], No. 12664/53. Class 146(3) A writing instrument having a retractable e writing point comprises a tubular casing c o ntaining 'a cartridge having a writing point at one end, a spring urging the cartridge into a retracted position, an axially displaceable and rotatable member engaging the cartridge, and a stop within the casing which can support the member in axially spaced - apart positions corresponding to the retracted and projected positions of the cartridge, the stop means comprising an annular member and an operating member which extends with the annular member and is movable axially relative thereto to cause partial rotation of the cartridge-engaging member relative to the stop. As shown, a ball-point pen cartridge 1 is retractable from the writing position, shown, into a casing 8 by means of a spring 6. The rear end of the cartridge has a cap 18 engaged by a spider 15 having radial projections 17 and a body slidable within a base 21 of an operating member 22, the spider 15 being pressed outwardly by a spring 25. The operating member 22 is slidable within an annular member 26 which fits tightly in a casing 10 secured to the casing 8 by a screwed plug 13. The inner ends of the members 22 and 26 have ratchet teeth 35 and 29 respectively displaced relatively through half a tooth pitch. The operating member 22 has one or more ribs 33 each engaging a groove 32 in the member 26. When a stud 23 carried by the member 22 is depressed the projections 17 slide down the grooves 32 to engage the inclined faces 36 of the teeth 35. The projections 17 tend to slide down the faces 36 due to the spring 6, thus rotating the spider 15 until the projections 17 engage faces 37 of the teeth 35. Upon releasing the stud 23, the member 22 is retracted, such that the spider 15 and thus the cartridge 1 are maintained in an advanced position by reason of the projections 17 engaging the faces 31 of the teeth 29. Further depression of the stud 23 causes the teeth 35 to engage the projections 17 and disengage them from the faces 31 of the teeth 29, such that the projections 17 slide down the inclined faces 36, thus rotating the projections 17 into a position opposite the grooves 32. Release of the stud 23 causes the projections 17 to be retracted along the grooves 32, such that the cart-' ridge 1 is retracted into the casing 8.
