Patent ES-8306189-A1 (ES)
Title: A method and an apparatus for the continuous plastic deformation of metal and for the pretreatment of said metal before said deformation.
IPC: C23G3/00
Filed: 1982-09-09
Abstract: The invention relates to the pretreatment of ductile non-ferrous metal to be deformed in a continuous plastic deforming device (20) in which the surface parts of the metal to be deformed do not substantially form surface parts of the metal after said deformation. Known methods of pretreatment include scaling off of thin surface layers and pickling e.g in baths and coiling or storing the metal thereafter before feeding to the deforming device. Such methods have disadvantages in view of energy, waste of material and, in many cases, in still having some surface contamination on the metal entering the deforming device. To avoid such disadvantages, the invention proposes to spray the metal with a deoxidation and cleaning agent in one throughgoing operation directly while it is moving to the deforming device and continuously and synchronously therewith. Spraying is done by directing forceful jets of the liquid onto the moving metal surface. The spraying agent is a strong alkali and for some types of alloys there is a further spraying step using an acid such as a strong nitric acid solution in water. The metal is thereupon, while moving on to the deforming device, rinsed with water and dried.

Title: Method and device for roasting coffee beans.
IPC: A23N12/08
Filed: 1983-09-29
Abstract: Apparatus for roasting small quantities of coffee (typically less than five pounds) includes a roasting chamber with base and cylindrical wall portions in fixed relation to each other. Disposed coaxially within the chamber is a downwardly extending tube that has an outlet orifice spaced from the base surface, and an exhaust outlet is in the upper portion of the chamber. A stream of hot roasting gas flowed downwardly through the central tube at high velocity for impact on the base surface and deflection radially outwardly and then flow upwardly through the exhaust outlet at the top of the chamber produces a toroidal circulation pattern of fluidized coffee beans with rapid and uniform roasting of the green coffee, in a simple and compact arrangement in which roasting parameters (such as fluid temperature and cycle duration) may be easily adjusted depending on the degree of roast desired.

Title: Pressure resistant submarine optical fiber cable
IPC: G02B6/44
Filed: 1985-04-18
Abstract: A submarine cable with optical fibers which prevents damage to the fibers due to water pressure without the use of an external armor. The cable has a central core with a strand which provides the cable tensile strength and which is surrounded and contacted by a layer of plastic material having helical grooves which receive the optical fibers which may have a protective covering. The layer of plastic material is surrounded by a thin metal sheath which, in turn, is closely surrounded by a layer of plastic material. The grooves and any spaces radially inwardly of the sheath, such as the spaces between the wires of the strands, are filled with a practically incompressible fluid, such as a grease or jelly. If the optical fiber protective layer is a tube loosely receiving the optical fiber, or optical fibers, the space within the tube not filled by optical fibers is filled with a substantially incompressible fluid. A further layer of plastic material may be interposed between the metal sheath and the plastic material layer of the core and may at least partially extend into the grooves.

Title: Nuclear reactor
IPC: G21C3/326
Filed: 1986-05-08
Abstract: A nuclear reactor in which control rods are inserted in the thimbles of only certain of the fuel assemblies (which may be called controlled assemblies) in the core and the remainder of the assemblies (which may be called non-controlled assemblies) are provided with hollow structural members containing burnable poison which form these non-controlled assemblies into integrated units. The hollow structural members are formed with end plugs welded to the lower end and are open at the top. The end plug of each member is secured to the bottom nozzle of the non-controlled fuel assembly. A skeleton is formed of the bottom nozzle, the structural members secured to it and a plurality of grids spaced along the structural members. A bulge tool is then inserted in each hollow member and it is on each side of each grid. Neutron absorbers are then inserted in each hollow member and an upper end plug is welded to it. The fuel rods are then inserted in the assembly and the upper end plugs are secured to the top nozzle. Typically, there are 24 thimbles in a controlled assembly but not all thimble locations in a non-controlled assembly contain neutron-absorber structural members. Typically, there are eight structural members in a non-controlled assembly. In the other positions there are fuel rods. In reactors where there are water displacement control rods which extend over several assemblies, the so-called non-controlled assemblies may have the necessary thimbles for the water displacement rods.

Title: Process for filling a siphon container with liquid
IPC: B65D83/14
Filed: 1986-07-01
Abstract: A siphon head 304 is configured in order to fit onto the neck 350 of a bottle 352 in a sealed relationship. On the outer surface 360 of the body 362 is mounted a lever 340 by means of breakage filaments and a spring sheet. During use, the user pulls the lever 340 up in order to break the filaments. The strip 230 causes one end of the lever 340 to pivot across the opening 342 of the body 362 and across the actuator shaft 348. The actuator shaft 348 is joined to the inner surface of the body 362 by means of an elastic diaphragm (membrane). The raised part 324 on the elastic sealing member 318 seals an opening in the siphon tube 310 until the force exerted on the handle 340 causes the rod 348 to move in order to allow dispensing of seltzer (water) 356. It is possible to manufacture the head 304 in a single injection-moulding operation. The head 304 is joined detachably to the bottle 352. The bottle 352 is transported with a cap over the neck 350. The user removes the cap and connects the head 304 for dispensing the seltzer 356. It is possible to re-use the head 304 with other bottles 352.
