Patent ES-409684-A1 (ES)
Title: Device to supply a thread
IPC: D03D47/00
Filed: 1972-12-09
Abstract: The invention relates to devices adapted to positively supply a thread or like elongated article under an approximately constant tension to a processing machine as it is pulled by the latter, of the kind comprising a thread advancing mechanism driven by a variable-speed electric motor, and two supports, such as pivoted levers, movable with respect to each other and urged apart by appropriate means such as springs, each carrying a number of guiding means between which the thread passes in zig-zag fashion, while means are provided to control the angular speed of the motor in such manner that it increases as the supports come nearer to each other and that it decreases when they move apart. In order to absorb the sudden variations of the linear speed at which the thread is pulled by the processing machine, as for instance a loom with stationary weft supply, in accordance with the invention the thread guiding means are carried by the movable supports through the medium of spring loaded pivoted arms of quite negligible inertia which follow closely the variations of the pulling speed of the thread without causing appreciable additional tensions. With such an arrangement the supports are practically only responsive to the variations in the average pulling speed of the thread.

Title: Gas-centrifuge unit and centrifugal process for isotope separation
IPC: B04B5/08
Filed: 1977-11-10
Abstract: An invention involving a process and apparatus for isotope-separation applications such as uranium-isotope enrichment is disclosed which employs cascades of gas centrifuges. A preferred apparatus relates to an isotope-enrichment unit which includes a first group of cascades of gas centrifuges and an auxiliary cascade. Each cascade has an input, a light-fraction output, and a heavy-fraction output for separating a gaseous-mixture feed including a compound of a light nuclear isotope and a compound of a heavy nuclear isotope into light and heavy fractions respectively enriched and depleted in the light isotope. The cascades of the first group have at least one enriching stage and at least one stripping stage. An example of such a gaseous mixture is uranium hexafluoride incorporating uranium-235 and uranium-238. The unit further includes means for introducing a gaseous-mixture feedstock into each input of the first group of cascades, means for withdrawing at least a portion of a product fraction from the light-fraction outputs of the first group of cascades, and means for withdrawing at least a portion of a waste fraction from the heavy-fraction outputs of the first group of cascades. The isotope-enrichment unit also includes a means for conveying a gaseous-mixture from a light-fraction output of a first cascade included in the first group to the input of the auxiliary cascade so that at least a portion of a light gaseous-mixture fraction produced by the first group of cascades is further separated into a light and a heavy fraction by the auxiliary cascade. At least a portion of a product fraction is withdrawn from the light fraction output of the auxiliary cascade. If the light-fraction output of the first cascade and the heavy-fraction output of the auxiliary cascade are reciprocal outputs, the concentration of the light isotope in the heavy fraction produced by the auxiliary cascade essentially equals the concentration of the light isotope in the gaseous-mixture feedstock.

Patent ES-482175-A1 (ES)
Title: Self-cleaning rotary filter for the cooling air inlet of an engine enclosure
IPC: A01D41/12
Filed: 1979-07-04
Abstract: The engine of a self-propelled combine is mounted in an enclosure having an inlet through which cooling air is drawn by an engine-driven fan. The air is filtered by a rotating disk-like screen mounted over the air inlet before passing through a radiator adjacent the inlet. A duct extends across the face of the disk from its center to periphery, changes direction and terminates with an open end adjacent the inlet side of the fan by-passing the radiator. The duct is also open adjacent the face of the screen so that the fan draws air through the duct, (some of the air being necessarily drawn from inside the screen as it passes the duct opening) so that foreign material filtered from the mass of cooling air being drawn through the unobstructed portion of the screen and held on the screen exterior surface is removed and carried through the duct. A trash knife rigidly attached to the periphery of the screen extends outwards parallel to the screen's axis of rotation. The knife is shielded by and travels within an annular channel-like shroud as the disk rotates. The shroud is connected with and intersects the duct so that as the screen rotates the knife passes through the duct, closely adjacent a shear bar supported there. The knife cuts or dislodges any foreign material lodged in the duct where it changes direction so that it may continue its passage carried by the air flow through the duct. A relatively flexible material with a high percentage open area is used for the filter element of the screen and is held taut by a compression spring pressing outwards on a thrust washer at the center of the screen to form it into a shallow cone.

Title: Method and apparatus for the control of fuel rods used in nuclear reactor assemblies.
IPC: G01N29/34
Filed: 1980-04-18
Abstract: A method of testing new fuel rods for assemblies for nuclear reactors. Ultrasonic waves are transmitted in the canning tube of the fuel element disposed in the open, with an oblique incidence with respect to the axis of the tube, from one region of the side wall of the tube. By reflection at the walls of the canning tube, these waves produce plate waves or Lamb waves. These Lamb waves are picked up after a certain distance has been covered along the length of the canning tube and the attenuation undergone by these Lamb waves is measured. From this, by comparison with the attenuation results obtained at another part of the length of the tube or with a standard tube, data on the possible presence of moisture in the fuel rod is deduced. The invention particularly applies to the testing of fuel rods of assemblies for a pressurized water nuclear reactor.
