Patent GB-967427-A (GB)
Title: Nuclear fuel element
Inventor: BOUDOURESQUES BERNARD
IPC: G21C3/38
Filed: 1963-08-12
Abstract: 967,427. Fuel elements. COMMISSARIAT A L'ENERGIE ATOMIQUE. Aug. 12, 1963 [Aug. 20, 1962],No. 31796/63. Heading G6C. A nuclear fuel element comprises a canned cartridge of fissile or fertile material centrally disposed in a jacket of low neutron absorption material by means of longitudinal partitions extruded integrally with the fuel can, said partitions having their longitudinal edges formed with teeth which engage in helical grooves in the inside surface of the jacket so that the can is screwed into the jacket. A rod 2 of pure or slightly alloyed uranium has its surface helically grooved as at 6, and a magnesium-zirconium alloy can 4 is interlocked with the grooves by hydrostatic pressure. End plugs 10 are welded to the can. The can has six sets of fins forming a herring bone pattern, divided by three equispaced longitudinal partitions 16, placed at the lines of demarcation between adjacent fin sets. Radial clearance 19 is provided to allow unrestricted expansion of the can. Additionally, a longitudinal clearance may be provided between the sides of the grooves and teeth, this clearance varying from tooth to tooth along the partition so that, when assembled cold, the can is supported only by the uppermost teeth; as longitudinal expansion takes place up to operating temperature, more teeth are brought into load supporting use until the load is shared by the maximum practicable number of teeth. By supporting the fuel in this way, no loading is placed on the welded end caps. The invention is also applicable to tubular fuels, and to cans having longitudinal fins.

IPC: C03B23/11
Filed: 1953-11-19
Abstract: 741,538. Glass ampoules. JOHNSEN & JORGENSEN FLINT GLASS, Ltd. Dec. 6, 1954 [Nov. 19, 1953], No. 32083/53. Class 56 In ampoule manufacture, to facilitate filling and subsequent sealing, means are provided to shape a portion of the stem to a predetermined outer diameter and concentricity to form a standard section in each ampoule. An apparatus for doing this includes an arm 1 mounted for swinging, movements in a horizontal plane about fixed pivots 2 outside the pitch circle upon which the chucks of the ampoule-making machine revolve. A member 4 slidably mounted on the arm carries rollers 6 which are engaged by the chucks during an arc of their movement. Such engagement moves the sliding member 4 against a spring 9 and such movement effects the following operations in sequence:-(a) swings a pair of open jaws 23 from the vertical position shown (in which they are clear of the stem of the rotating ampoule carried in the chuck) to a horizontal position wherein they lie on opposite sides of the stem; (b) closes the jaws with an adjustable pressure on to the stem and (c) lowers (through a link and lever system 45...48) the member 11 by which the jaws 23 are supported, thus causing the jaws to exert a wiping action on the stem as they descend. These actions are reversed as the chuck in its continued movement rides clear of the rollers 6 and allows the slider 4 and arm 1 to be repositioned to engage the next chuck.
Patent GB-1339382-A (GB)
Title: Discharge-lamp supply arrangement
IPC: H05B41/282
Filed: 1972-07-10
Abstract: 1339382 Supply circuits for discharge lamps; inverters PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 10 July 1972 [13 July 1971 25 Jan 1972] 32131/72 Headings H2H and H2F [Also in Division G3] A circuit for supplying at least one low pressure mercury vapour discharge lamp 49, 50 comprises a D.C. to A.C. converter including a transistor 8 controlled by an auxiliary oscillator including a transistor 6, and a variable resistor 25 in the control circuit of the transistor 6 for varying the waveform of the voltage supplied to the base of the transistor 8. The auxiliary oscillator supplies an alternating signal via an R-C circuit 39, 40 to the base of a pro-amplifying transistor 7, the positive half cycles switching on the transistor 7. A transformer 29 therefore switches on the transistor 8 to enable current to flow from a D.C. supply terminal 26 through the primary winding 41 of a transformer 42. The lamps 49, 50 are connected across the secondary winding 43 via respective ballast capacitors 51, 52 each of which forms an oscillatory circuit with its respective lamp so that each positive pulse supplied from the winding 41 is followed by a negative pulse. Adjustment of the resistor 25 alters the width of the half cycles supplied to the transistor 7 thereby increasing or decreasing the conduction period of the transistor 8 to increase or decrease the output power of the transformer 42. Lamps of varying wattages can therefore be supplied without reducing the efficiency of the converter. A circuit 60 switches off the transistor 6 after a delay of several seconds if no load is connected across the winding 43. Fluctuations in the output voltage of the transformer 42 are compensated by a winding 47 which controls the base voltage of the transistor 7.
