Patent GB-1184188-A (GB)
Title: Improvements in or relating to Nuclear Reactors
Inventor: PACKMAN GORDON
IPC: G21C19/04
Filed: 1966-10-21
Abstract: 1,184,188. Fuel elements. UNITED KING- DOM ATOMIC ENERGY AUTHORITY. 10 Oct., 1967 [21 Oct., 1966], No. 47423/66. Heading G6C. The levitation of a fuel stringer within a fuel channel of a nuclear reactor is resisted by the use of a coolant pressure difference. In the embodiment illustrated, a component 1 of a fuel stringer, e.g. a neutron scattering plug, has an extension 3 of reduced external size, a further component 4 sealing between the extension 3 and the wall 2 of the fuel channel. The component 4 has a pair of sliding seals 5 contacting the wall 2 and a pair of sliding seals 6 contacting the extension 3, and is held stationary with respect to the channel. As described in Specification 882,714, part of the fuel coolant flow, i.e. pressurized gas, is introduced at a pressure in excess of that prevailing elsewhere in the channel by means of passages 7 into the annulus between the component 1 and the channel wall 2 and flows downwards through the core at the bottom of which it joins other coolant flow and passes up through the interiors of the fuel elements of the stringer and the component 1. The pressurized gas from the passages 7 enters the space between the components 1 and 4, the component 1 acting as a plunger exerting a downward pressure on the sleeves of the fuel elements on which it rests. Levitation of the fuel elements is thus resisted. The component 4 carries a spider 8 through which extends a tie-rod 9 having an upper termination 10 which, after the spider is raised a short distance, abuts on the spider and lifts the tie-rod 9, this in turn raising the fuel elements. A connection 12 releasably connects a component 11 to the component 4. The component 11 is normally a spacing piece connecting the fuel and neutron plug parts of the stringer with parts having a gag valve and a shield and seal plug serving to close the respective refuelling access aperture in the reactor pressure vessel. The component 4 has a lost motion interconnection 18 with the component 1 consisting of abutments 19 and 20 adapted to cooperate after a certain degree of raising of component 4 relative to component 1 in excess of the abovementioned short distance. On raising the stringer, an upward pull on component 11 is transmitted to component 4 which when raised beyond the short distance lifts the fuel elements. The pressure resisting levitation continues to hold down component 1 until the seals 5 are clear of the channel. The abutments 19 and 20 are not brought into contact until after removal of the stringer from the reactor when they support the component 1 after the tie-rod 9 has been severed. The force resisting levitation may, if desired, be utilized only during refuelling by arranging components 1 and 4 so that they completely close together when the stringer is fully inserted with the weight of component 4 holding down component 1.

Title: Tape Recorders
Inventor: PAPST GEORGE FRIEDRICH
IPC: G11B15/10
Filed: 1966-10-24
Abstract: 1,165,366. Tape recorders. G. F. PAPST. 24 Oct., 1966 [25 Oct., 1965; 2 July, 1966; 8 July, 1966 (2); 27 July, 1966], No. 47697/66. Heading G5R. A tape recorder comprises a deck for receiving a sound tape cassette, wherein the deck is mounted for limited displacement in a plane parallel to a face of the recorder, and wherein any one operative condition of the recorder is adapted to be established by selective displacement of the deck to one of its limits of displacement. A tape cassette 10, Fig. 4, including loaded spool and take-up spool is located on a displaceable deck 2 forming part of a recorder, the deck incorporating mandrels 26 and 15 for loaded spool and take-up spool respectively, and a tape-transporting capstan 9, all of which project into the cassette. The deck also incorporates pins 3, Fig. 2, engaging fixed slots 4. When the cassette and deck together are moved (downwards in the plane of the drawing) to the record/playback position shown in Fig. 2, a flywheel 7 on the shaft of capstan 9 is forced into engagement with the drive shaft 6 of a motor 5 mounted in a yoke 30 pivotable about a fixed pin 27. At the same time a guide pin 18 on deck 2 moves linkage 16, 16<SP>1</SP> about a fixed pin 17 to effect engagement of a friction wheel 13 with a friction roll 12 (extending below flywheel 7) and with a friction disc 14 connected to mandrel 15 to drive the mandrel. At the same time the tape 11, Fig. 4, is engaged between capstan 9 and a pressure roll 9<SP>1</SP>. For rapid wind the deck 2 is moved upwards and to the right, whereupon contact between shaft 6 and flywheel 7 is maintained, but friction wheel 13 is displaced, while another friction wheel 20 is brought into contact with flywheel 7 and with a friction disc 21 connected to mandrel 15 to drive the mandrel. For rapid re-wind, the deck is moved upwards and to the left so that shaft 6 drives mandrel 26 through flywheel 7, an intermediate wheel 22 rotating about an axis fixed to the recorder frame, a friction wheel 24 and a friction disc 25. The cassette may incorporate a protuberance capable, in one cassette position, of switching off the erasing (and recording) heads to prevent accidental erasing of the tape. In a modification, the motor 5 is secured horizontally to a plate fixed to deck 2 and is permanently connected by belt and pulleys with the flywheel 7. This modification may be further modified by having a further flywheel, driven by the same motor, with its capstan directed downwards, and a further deck 2 on the underside of the recorder. This further deck is used to accommodate a cassette having different dimensions and a different playing speed. A pin displaced by the locating of either cassette on the recorder prevents the locating of the other thereon at the same time. In a further alternative, the two decks may be on the same face of the recorder.

Title: Carburettor automatic choke construction
IPC: F02M1/12
Filed: 1972-10-18
Abstract: 1392130 Spray carburetters FORD MOTOR CO Ltd 18 Oct 1972 [2 Nov 1971] 47896/72 Heading F1B Automatic choke system for use with a carburetter having an air/fuel induction passage and an unbalance-mounted air-movable choke valve to control air-flow through the passage, thermostatic spring means operably connected to the choke valve, urging the choke valve towards a closed position with a force increasing as a function of decreases in the temperature of the spring means from a predetermined level, and a self-limiting- output-temperature, electrical heater device located adjacent the spring means operable to transfer its heat output thereto to reduce the choke valve closing force of the spring means and permit opening of the choke valve by air-flow through the passage against it. The carburetter choke valve 28 is connected by a rod 52 to a lever 48 secured to one end of a shaft 44, on the other end of which is fixed an L-shaped lever 54. The lever is slotted to receive the outer end of a coiled bi-metallic spring 60, the inner coil of which is fastened to a post 84. Integral with the post is a metal disc 85 which has an electrical heater 86 secured to the face opposite to that carrying the post. The spring is contained in a chamber formed by a housing 42 and a gasket 64 having an arcuate slot through which the L-shaped lever 54 projects. Air heated by the exhaust manifold is drawn through the chamber to heat the spring so that the choke valve is opened by the force of the air-flow. There is also a kick-piston which slides in a cylinder connected by a passage 80 to the intake pipe immediately downstream of the throttle valve 36, so that the choke valve is partly opened as soon as the engine starts. When the ambient temperature is high, the period of time for which the choke is in operation can be reduced, and to effect this the electrical circuit of the heater 86 includes a bi-metal switch 94 which closes at 65F. As the temperature of the heater device increases, its resistance remains almost constant up to a temperature of about 120F and the resistance then increases rapidly with increasing temperature until at about 150F the resistance limits the current flow to such an extent as to prevent further rise in temperature of the heater.

[Also in Division G6] Spent nuclear fuel in oxide form is fluorinated in a fluidized bed with a mixture of O 2  and F 2  at about 350 C. to produces gas containing UF 6 , and fluorinating the remaining fuel in a fluidized bed at about 500-550 C. with a mixture of O 2  and F 2  containing a high proportion of F 2  to produce a gas containing PuF 6 ; the gaseous fluoride streams are separately purified, condensed, combined, and batch distilled to a fluidized bed at about 350 C. where UF 6  passes through and PuF 4  remains in the bed; F 2  is then passed through the bed at 500 C. to form a stream of PuF 6  and the purified UF 6  and PuF 6  streams are passed to a bed fluidized with steam and H 2  to produce mixed PuO 2  and UO 2 . Fast breeder fuels may be treated for decontamination from fission products. Stainless steel cladding is removed mechanically from fuel elements and the oxide fuel is pulverized, mixed with alumina and treated as a fluidized bed with a mixture of F 2  and O 2  at 350 C. in reactor A. Most of the uranium volatilizes as UF 6  together with some of the plutonium and fission products. The residue is transferred to fluidized bed reactor B where it is fluorinated in two stages at 500 and 550 C. to volatilize PuF 6 . The volatile streams from reactors A and B are each passed through a cooler at 15 C. to separate NbF 5  and RuF 5  and then to cold trap at -80 C.; the condensed UF 6  and PuF 6  are combined and introduced into a fluidized bed of alumina at 350 C. where PuF 6  is converted to PuF 4 , UF 6  being removed and passed through LiF and NaF traps to two multi-stage distillation columns where farther fission product fluorides are removed, and then through a MgF 2  trap to separate TcF 6  and a combination NaF-UO 2 F 2  trap to separate NpF 6  and F 2 . The PuF 4  is treated with F 2  at 500-550 C. and purified PuF 6  condensed. An oxide mixture for re-use as nuclear fuel is formed by leading the purified UF 6  and the purified PuF 6  to a bed of oxides of U and Pu at 650-1700 C. fluidized with a mixture of steam and H 2 . The purification process also removes oxyfluorides of Ru, Tc, Mo, and I. Solid wastes are mixed with Al shot or powder and stored. Gaseous wastes are passed through a fluidized bed of activated alumina to remove F 2  and through a soda lime trap to remove I 2  and tritium fluoride.
