Title: Improvements in and relating to moving bed reaction systems
IPC: B01J27/06
Filed: 1963-07-08
Abstract: <PICT:0996718/C1/1> In the production of chlorine by alternate oxidation and chlorination of active constituents comprising a polyvalent metal oxide/chloride on an inert support, said active constituents are renewed whilst passing through at least one reaction vessel at high temperature by injecting finely divided active constituents into or immediately before a zone in which said constituents are in a pasty condition. In the Figure, granular masses comprising alumino-siliceous cylinders impregnated with ferric oxide, potassium chloride and cupric (or cadmium) chloride (promoter), are fed from reservoir 11 to chlorination vessel 1 via a channel 2 into which pulverized potassium chloride is blown from reservoir 12. Chlorination is effected at 450-550 DEG C. Hydrogen chloride and/or ammonium chloride is introduced at 3 whereby the ferric oxide is chlorinated to form ferric chloride, and water and/or ammonia formed simultaneously is removed at 4. The granules pass through channel 5 to oxidation vessel 6, iron filings being injected into the upper empty part of vessel 6 and air being admitted at 7, the vessel being maintained at 530-560 DEG C., and chlorine and nitrogen are removed at 8. The granules are finally returned to reservoir 11 by means of an air lift or trough-conveyer. The potassium can alternatively be injected as carbonate or hydroxide and the iron and copper as chloride, carbonate or oxide.

Title: Device for connecting and sealing-off between two sections of a pipeline for conveying liquefied gas
IPC: F16L29/02
Filed: 1965-11-18
Abstract: Means for sealing off the connection between the inner tubes of two coupled pipe sections A and B, each section comprising arcuate inner and outer tubes 2, 16 and 1, 18 respectively having a sealed annular space therebetween, comprises a conical plug C carried by a control rod 48 passing through tubular terminal extension portions 27 and 29 of the section B at right-angles to the inner and outer tubes of said section, said valve being adapted to stop the flow of a liquefied gas from pipe 2 to pipe 16 on rotation of the control rod nut 55. Said plug is adapted to seat on an annular seal 41 which is clamped between rings 40 and 5 secured to the terminal portions of the inner tubes 2 and 16 when the sections are coupled together by a screwring 31. The arrangement is such that the sections may be uncoupled and annular seal when worn replaced without the evacuated annular space of either pipe section being destroyed. The innermost end of the inner pipe of section A is connected by ring 5 and a tubular sleeve 3 to one end of outer tube of said section whilst the outermost end of the inner pipe is connected to a sleeve 7 secured to the other end of the outer pipe by a bellows 11, which permits relative expansion between the inner and outer pipes whilst maintaining a vacuum therebetween. The tubular sleeve 3 is received in the terminal portion 27 of the tube 16 and is sealed thereto by compression of a sealing ring 33 when a further screw-ring 30 is tightened. Expansion bellows 50 and 52 disposed between the control rod and the terminal portion 27 of the inner tube of section B and between the control rod and the terminal portion 27 of the outer tube 29 of section B ensure the maintenance of the evacuated space 18 of said section.
Patent ES-330210-A1 (ES)
Title: Grabs for handling nuclear fuel elements
IPC: G21C19/105
Filed: 1966-08-12
Abstract: To remove a nuclear fuel element 80, Fig. 4, from a hollow nozzle 81 where it is held by balls 83 which are pushed outwards by a spring-loaded sleeve 84 a grab 1 is lowered into the hollow head of the element and latched thereto by balls 34. The balls 34 are urged outwards by a slide - block 29 which is moved up the grab by a screw 18 turned in a fixed nut 19 by an electric motor 9 and a sleeve 12. When a rod 35, which moves with the slide block 29, closes contacts 36 the motor 9 stops. After a time delay a second motor 66 is energized and pushes arms 69, 70, Fig. 4, out of slits 79, 80, Fig. 1, by rotating a differential housing 50. The housing 50 is prevented from further rotation by the arms 69, 70 when the latter are fully extended. Continued rotation of the motor 66 causes rotation of a screw 42 in a nut 43, through the differential gearing, which raises the differential housing 50 and the arms 69, 70. The latter slide up slots 79, 80 until the end of a pile of spring washers 40 abuts the lower end of rod 25. The motor 66 is now stopped by a contactor, or, if this fails, by the excess current taken by the motor. As the arms 69, 70, Fig. 4, are raised by the screw they push the sleeve 84 upwards to a position in which the balls 83 are received in grooves 90. This releases the element 80 from the nozzle 81 and since it is attached to the grab by balls 34 it may be lowered and removed.

Title: Reorientation of fibers in a fluid stream
IPC: D04H1/74
Filed: 1972-10-06
Abstract: Fibers in a fluid stream, predominantly oriented in the stream direction, are reoriented by passing the stream into a curved enclosure which subjects the fibers to a centrifugal action which tends to realign the fibers in a direction normal to the fluid flow. By introducing artifical turbulence into the air stream, the orientation of the fibers may be varied from substantially random to substantially normal to the fluid flow. Associated means are provided for converting the fluid stream of fibers into a fibrous web with a controlled fiber orientation.

Title: Steam generator
IPC: F22B1/02
Filed: 1973-09-03
Abstract: A steam generator includes a U-shaped nest of tubes having vertical legs with their lower ends mounted in the holes of a circular tube sheet and centrally forming a vertical corridor or passage extending upwardly from the tube sheet, the nest and the upper surface of the tube sheet being enclosed for containment of water and generated steam. Feed water flows radially inwardly from the periphery of the tube sheet towards its center, the heating fluid flowing through the tube's nest via the tube sheet's lower surface. To prevent the feed water from prematurely converting to steam, or boiling, on the upper surface of the tube sheet and in the corridor or passage, means are provided for reinforcing the inward radial flow force of the feed water, assuring an adequate flow of the feed water throughout those areas to prevent such premature boiling or conversion to steam.
