Patent ES-363371-A1 (ES)
Title: Supple sheet material and method of producing same
IPC: D04H1/50
Filed: 1969-02-07
Abstract: A supple sheet material suitable for the manufacture of artificial leather comprises a non-woven densified web which comprises substantially hydrophilic fibres and a polymeric filler which has substantially no adhesion to the fibres and is homogeneously distributed throughout the web and coheres substantially via the spaces between the fibres, wherein the sheet material has a density of at least 0.5 g/cc. and a polymeric filler content of not more than 30% by weight of the sheet material. Hydrophilic fibres are considered to be fibres which when placed in a moist atmosphere at 20 C whose relative humidity changes from 50% to 95% will show a moisture pick-up of at least 7% of their own weight. The hydrophilic fibres may be polyvinyl alcohol, which may be water shrinkable and crimped or regenerated cellulose or mixtures thereof. The non-woven fibrous web may contain up to 5% of non-hydrophilic fibres such as nylon, polyester or polypropylene. The polymeric filler is preferably polyurethane or a nitrile rubber. The unfilled fibrous web may contain a binder such as a rubber latex, an isocyanate, an acrylate rubber, an alginate or a carboxy methylcellulose to temporarily maintain the high fibre density which may be applied to the web as a suspension or dispersion, and which may be removed in subsequent treatment. In a preferred embodiment, the binder is 5 to 10% and the polymeric filler is 10 to 20% by weight of the sheet material. The formed non-woven web may be needle punched followed by a shrinking treatment during which the binder may be added. The dried web is pressed at an elevated temperature of at least 120 to produce a web of density of at least 0.5 g/cc. The filler may be applied as a solution followed by its precipitation by a non solvent or by cooling. Further conventional leather processing may be effected on the supple sheet produced as may finishing applicable to synthetic leather.

Title: Fuel subassembly for a liquid-metal-cooled fast reactor
IPC: G21C3/32
Filed: 1969-04-09
Abstract: A fuel subassembly for a liquid metal-cooled fast nuclear reactor comprises a shroud containing a bundle of slender, elongated, parallel fuel pins, each of which includes a fuel zone and a fission-gas plenum, the ends of the fuel zones of all the fuel pins lying in parallel planes perpendicular to the axis of the subassembly, with the fuel pins being so oriented that some of the fission-gas plenums are located downstream of the fuel zones and the remainder are located upstream of the fuel zones. In one embodiment described, a group of fuel pins at the centre of the fuel subassembly have their gas plenums below the fuel while the remaining fuel pins have their gas plenums above the fuel. Two adjacent outer and inner fuel pins 15a, 15b respectively are shown in Figs. 6 to 8, both including a tube 38 enclosing PuO 2 /UO 2 pellets 40 which make up the fuel zones 13. Pellets 41 of depleted UO 2 are disposed above and below the fuel zones 13 to serve as an axial blanket while nickel rods 42 are disposed above the fuel zones 13 to serve as an axial reflector. Springs 43 are disposed above rods 42. The fuel pins differ only in the location of the fissiongas plenums 44 which are formed by stainless steel tubes 45. In the outer fuel pins 15a the plenums 44 are disposed above the fuel zones 13 between springs 43 and upper end fittings 22, while in the inner fuel pins 15b they are disposed below the fuel zones 13 between pellets 41 and lower end fittings 29. This embodiment was specifically designed for use in a reactor which required the lower end of each fuel subassembly to be tapered. Where this is not necessary, alternate rows of fuel pins may have their fissiongas plenums located on one side of the fuel zones and the remaining rows have their plenums on the other side of the fuel zones. Reference has been directed by the Comptroller to Specification 1,139,968.

Title: Method and apparatus for detecting the faulty operation of spinning units open-end spinning machines
IPC: G01N33/36
Filed: 1977-01-14
Abstract: A method and apparatus of detecting faulty operations of spinning units of an open-end spinning machine by monitoring the faults appearing in the yarn being produced by the machine and generating a fault signal responsive thereto. Another speed responsive signal is produced responsive to the speed that the yarn is being delivered from the spinning compartment of the machine. The fault signal is fed to a variable gain amplifier which has its gain controlled by the speed responsive signal. The signal produced by the amplifier is then differentiated, shaped, and integrated. The integrated signal is, in turn, compared with a threshold value for determining when the faults in the yarn exceed a predetermined level.
