Title: Improvements in or relating to heterogeneous liquid moderated nuclear reactors
Inventor: CAMPBELL CLIFFORD GRAHAM
IPC: G21C19/02
Filed: 1961-07-10
Abstract: 934,612. Nuclear reactors; handling radio-active materials. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. June 26, 1962 [July 10, 1961], No. 24851/61. Class 39 (4). A liquid moderated nuclear reactor comprises a container for liquid moderator and means for locating a plurality of frames in planes parallel to one another within the container, each of the frames being adapted to releasably retain nuclear fuel bodies. In Fig. 1 the reactor core is housed in a tank 1 containing liquid moderator, and nuclear fuel rods 2 are mounted in a series of frames 3 arranged in parallel planes within the tank. The frames 3 are provided at their upper comers with sockets 3a, which engage pins 4 mounted on the tank, and at their lower corners with projections 3b which engage with slots in the rack 5 to maintain the frames in parallel vertical planes. Each pin 4 is tubular, as shown in Fig. 2, and is supported by a bracket 7 which also supports a mounting for a latch 8 provided with a bolt portion 9 which can engage a laterally-extending plate 3c carried by the frame 3. Guide rods 6 for use during loading and unloading are provided with spigots 12 which are inserted in the pins 4, each spigot being provided with a portion 12c of square section which engages a square section aperture in the latch 8; a plate 10 provided with a square section aperture prevents the rod 6 from being withdrawn unless the latch is in the locked position. The top corner of each frame 3 is yoked at 14, the arms of the yoke being joined by a cross-pin 15 adapted to be engaged by a latch provided on a transport beam 13. Fig. 4 shows a part of the top of the tank fitted with a slidable lid 20 provided with three slots 21 (of which only one is shown), sealing between the lid and a fixed containment structure 22 being provided by an inflatable seal member 23. Each of the slots 21 is framed by an upwardly-projecting beading 24 retaining a further inflatable tubular seal 25. When there is a risk of contamination of the atmosphere round the core during loading or unloading, the frame containing fuel elements is enclosed in a collapsible cover 26 comprising rigid top and base plates and side walls 29 of concertina form made of synthetic plastic material. In use the cover encloses the loading beam 13 and the fuel frame 3 and the whole assembly is brought into position above the lid by a gantry crane. The detachable bottom plate 28a is removed and the bottom skirt 28b of the cover is attached in sealing engagement with the beading 24 and the seal 25 is inflated. The frame 3 is then lowered through the slot and the cover side walls 29 are allowed to collapse.

IPC: C10L5/14
Filed: 1925-10-06
Abstract: 263,942. Tapping, A. Oct. 6, 1925. Emulsions, making.-A binder for briquetting fuel, minerals, earths, &c. consists of a homogeneous mixture of a solid bituminous substance and an aqueous pulp of a starch-bearing vegetable material with or without a small amount of an alkaline substance and a preservative, the incorporation of the ingredients in equal or any other proportions being effected under heat and pressure. An enclosed vessel having stirring gear and a pressure gauge and valve may be employed, the vapour pressure being controlled so as to maintain the temperature above the melting point of the bituminous ingredient and so as to regulate the amount of moisture required in the final product. As the, bituminous substance mav be employed coal tar pitch, bitumen, natural asphalt or the residue from the distillation of asphaltic petroleum or mixtures of these substances ; the aqueous pulp may be made from prepared starch, the flour or meal of wheat, barley, rice, maize &c., or from peas, beans, potatoes, artichokes, acorns, chestnuts, cassada, cotton seed, flax-seed, hemp-seed, or waste products such as bran, chop, brewers' waste, husks, peelings, shells, &c. Soda, ammonia or sodium silicate may be used as the alkaline substance, and salicylic acid cresol, phenol, or formaldehyde as the preservative. As discharged from the mixing vessel the binder is in semi-liquid form and may be added directly to the pulverized material to be briquetted. or it may be allowed to set and then ground before mixing with the material.

Abstract: 778,456. Air-blast switches. I-T-E. CIRCUIT BREAKER CO. Aug. 27, 1954 [Sept. - 4, 1953], No. 24986/54. Class 38(5) An air puffer blowing an arc from the 'contacts 23, 24 towards the arc-chute comprises a piston 32 connected by a linkage 38, 40 to the operating arm 42 and movable in a cylinder 30. When the breaker opens, the piston 32 moves from left to right to force a stream of air through an orifice 52b, tube 55a and nozzle 57a, that portion of the stroke when piston 32 has passed aperture 52b acting as a buffering stroke to prevent rebound of the contacts. Air intakes 60 are provided in one end wall of the cylinder, and an air bleed clearance with adjustable means 63 is provided round the piston rod 37. In another embodiment (Fig, 4, not shown) an adjustable small air vent and an :air intake are provided so that buffering also occurs at the end of the closing stroke. In Fig. 5, an auxiliary piston 72 is driven to the right by piston 32 to provide the buffering action for the opening stroke, the movement of piston 72 to the left being limited by engagement of a pin 95 on piston rod 73 with end wall 62 of the cylinder. Three circumferentially-aligned orifices 52b are provided for a three-pole breaker. Specification 763,747 is referred to.

Abstract: 837,082. Valves. PHILLIPS, R. R. Aug. 5, 1958, No. 25022/58. Class 135. Pressurized gas in a container F, Fig. 1, is released through a manually operable step valve O at a predetermined lower pressure controlled by a reducing and regulating valve V. The valve O comprises a casing 8 the wall 16 of which has an orifice 17 which communicates with the interior of the container F and is controlled by a closure member 23 carried by a hollow screwed stem 4 to the outer end of which the valve V is attached. The valve O has an actuating bail 3. The valve V comprises a shell 44 screwed to a body 40 screwed to the stem 4. The body 40 has aligned passages 45, 46 leading to an inlet chamber 47. The passage 46 is controlled by a closure member 54 on the stem 53 of a piston 59 movable in the shell 44. The chamber 47 communicates with an outlet and is connected via passages 64, 65 with a pressure chamber 62 defined by the piston 59 and a piston-like member 63 in the shell 44. A spring 52 loads the piston 59 to bias the closure member 54 away from the passage 46 and is opposed by a spring 66 and the pressure in the chamber 62. The member 63 is positionally adjustable by a screwed spindle 70 to determine the loading of the spring 66 and so determine the regulated pressure in the chamber 47 which is connected to a pressure gauge. The piston stem 53, the piston 59 and the member 63 have annular sealing rings. The valve V may be arranged at right angles to the valve O in which case an adapter connects one to the other.

A continuously-variable-ratio gear comprises two simple trains of planetary gearing having two pairs of their gear elements connected together, each of the two pairs of elements being connected to the pump and turbine of an hydraulic torque converter. In one form, an input sun gear 11 drives through planet pinions 12 and a ring gear 13, comprising a first planetary train. A carrier 14 journals the planet pinion 12 and also journals further planet pinions 16, meshing the ring gear 13 and a second sun gear 15, the latter elements comprising a second planetary train. The two ring gears 13 of the planetary trains are fast with the pump 18 of an hydrodynamic torque converter, shown diagrammatically externally of the two planetary trains, but actually located spatially between them. The two sets of planet pinions 12, 16 on the common carrier 14 are connected with the torque converter turbine 19, and the sun gear 15 drives an output shaft 22. A one-way detent 23 stations the reactor 20 of the torque converter. In a modification, an input shaft 50, Fig. 2 (not shown), drives through a first planetary train having bevel planet pinions 52 on a carrier 54 geared through a countershaft train 58 to the turbine 62 of an hydrodynamic torque converter, the output sun gear 53 of the planetary train driving the input bevel sun gear 69 of a second planetary train, both of which sun gears are fast with the pump 63 of the torque converter. Planet pinions 71 of the second train are on a carrier 70 fast with the turbine 62 geared to the planet carrier of the first train. The second sun gear 72 of the second train drives an output shaft 73, and the reactor 64 of the torque converter can be stationed by a oneway brake 67.
