Title: Improvements in or relating to methods of recrystallizing filaments for incandescentlamps or heaters
IPC: H01K3/02
Filed: 1958-12-15
Abstract: 904,920. Making filaments for incandescent lamps or heaters. PHILIPS ELECTRICAL INDUSTRIES Ltd. Dec. 15, 1958 [Dec. 18, 1957], No. 40345/58. Class 39 (2). In the process of recrystallizing a filament of high melting-point metal, e.g. tungsten, for an incandescent lamp or heater, by passing a current through the filament while this is in a magnetic field, a capacitor discharge is passed through the filament after the current is switched off. The filament 8 is carried by lead-in wires 4, 5 with or without support wires 6, 7 in a mount consisting of a stem 2 and pinch 3, the lead-in wires being connected to the terminals 11, 12 of a direct current source, with the interposition of a double-pole switch 15. Capacitors 24, 25 are connected across the leads 18, 19 between the switch 15 and the lead-in wires, chokes being connected in series in one of the leads. The filament is supported between the poles 26, 27 of a magnet. The arrangement obviates a sudden drop in the field of force when the current is switched off.

Abstract: 1279603 Fuelling reactors BRITISH NUCLEAR DESIGN & CONSTRUCTION Ltd 26 Aug 1969 [11 Sept 1968] 43118/68 Heading G6C The core of a gas-cooled reactor comprises moderator columns 1 having channels containing fuel elements arranged in triangular lattice formation in groups of seven columns. For refuelling purposes a standpipe 7 penetrating the top end cap 8 of the pressure vessel is provided for each group and is aligned with the centre of the group. Standpipes 5 penetrating the lower end cap 6 of the pressure vessel are provided, one for each column 1. An extension tube 4 of each standpipe 5 supports its associated column 1 by means of a support plate 3 and lifting grid 2. Coolant gas from a lower void 11 enters the tubes 4 through apertures 12, passes upwards through the columns 1 and enters an upper void 9. Refuelling may be performed whilst the reactor is operating, an upper fuelling machine 14 being inserted through the appropriate standpipe 7 and a lower fuelling machine 15 being coupled to the appropriate standpipe 5. To prevent gas flow through the void formed in the core when a column 1 is removed whilst permitting gas to continue to flow through the column, a gas flow control tube 21 is raised by a chain elevator 22, 23 from the machine 15 through the extension tube 4 so that the top end 25 of the tube 21 engages the lifting grid 2 of the column 1 to be removed. The tube 21 has four longitudinallyextending lines of flap valves 24 whereby valves opposite the apertures 12 are opened by the gas pressure so that the gas enters the tube and flows through the column 1 into the void 9. However, the gas pressure within the tube 21 holds the other flap-valves 24 closed so that the coolant gas does not enter the core void formed as the tube is further raised to lift the column 1 out of the core. The column 1 is lifted into a guide tube 17 of the fuelling machine 14, this tube being laterally movable from within a rotatable support tube 16 so as to be aligned with the column. When the column 1 has been raised into the guide tube 17 a latch 19 of the latter is operated to engage the bottom of the column and the tube is retracted into the tube 16, the column 1 now being lifted into the machine 14 leaving a neutron shield assembly 10 and the grid 2 supported on the tube 21.
