Patent ES-463976-A1 (ES)
Title: Transducer assembly, ultrasonic atomizer and fuel burner
IPC: B06B3/00
Filed: 1977-11-08
Abstract: A transducer assembly includes a first half wavelength double-dummy section having a pair of quarter wavelength ultrasonic horns and a driving element sandwiched therebetween. A second half wavelength stepped amplifying section extends from one end of the first section and has a theoretical resonant frequency equal to the actual resonant frequency of the first section. When used as a liquid atomizer, the small diameter portion of the stepped amplifying section has a flanged tip to provide an atomizing surface of increased area. To maintain efficiency, the length of the small diameter portion of the second section with a flange should be less than its length without a flange. A decoupling sleeve within an axial liquid passageway eliminates premature atomization of the liquid before reaching the atomizing surface. In a fuel burner incorporating the atomizer, ignition electrode life is increased by locating the electrodes outside the normal flame envelope. During the ignition phase, drive power to the atomizer is increased to widen the spray envelope to the location of the electrodes. A variable orifice controls combustion air flow in accordance with fuel rate while maintaining constant lower speed. Either three-step or continuous fuel rate modulation saves fuel and reduces pollution.

Title: Dual pore-structure artificial carbon and graphite
IPC: B01D53/02
Filed: 1978-04-28
Abstract: Dual pore-structured carbon and graphite consist essentially of a macroporous agglomeration of strongly bonded microporous grains of carbon or graphite the radii of the macropores therein being from substantially 10 to 350 mu m and those of the micropores from substantially 0.2 to 1.0 mu m, with the macropores being joined by intercommunicating channels which form a fluid permeable structure. Such carbon or graphite has a density of from 0.70 to 1.50 grams/cc., a permeability to gases of from 20 to 500 cm2/sec/atmos and a porosity of from 30 to 50%. Such materials are produced by including in a mixture of tar or pitch and finely divided solid carbonaceous material in suitable proportions, a particulate eliminable non-carbon-forming material having a particle size of 10 to 350 mu m, which material is substantially insoluble in said mixture, in a proportion sufficient to secure the desired porosity, shaping and then heating the mixture to effect carbonization and/or graphitization thereof and, after the product has cooled, giving any appropriate after-treatment to eliminate any heat treated residue from said particulate material and leave the desired porous structure.

Patent ES-8103966-A1 (ES)
Title: Heart valve prosthesis.
IPC: A61F2/24
Filed: 1980-08-06
Abstract: Single or double-leaflet heart valves (11) having improved flow (19) through the orifice defined by an annular valve (13) body include a pair of leaflets (15) which may be arcuate or flat in cross section. Guides (35) protrude oppositely from the leaflets and are received in complementary depressions (21) in the interior wall surface preferably of a pair of standards (23) which extend downstream from the annular valve body at generally diametrically opposite locations. The depressions (21) are preferably elongated so that, as the leaflets (15) pivot between the open and closed positions, the guides (35) move from one end of the elongated depressions (21) to the other. Eccentric pivot axes provide for quick response of the leaflets, and the location of the depressions (21) in the standards (23) moves the leaflets (15) out of the annular valve body, reducing resistance to the free flow of blood therethrough. The leaflet (15) valve members are preferably arcuate in cross section and may be essentially a portion of the wall of a circular tube.

Three additional rollers are located between the other two guide rollers and project outwardly from the surface of the main body opposite the one surface.
Patent ES-8200167-A1 (ES)
Title: Fuel injection pump
IPC: F02M41/14
Filed: 1980-10-16
Abstract: A fuel injection pump of the rotary distributor type has angularly adjustable stop rings which limit the outward movement of the pumping plungers so as to control the maximum fuel output of the pump. The stop rings have an outwardly extending curved stop surface so that the maximum fuel output can be altered by altering the angular setting of the rings. The latter portion of the stop surface is arranged to curve outwardly at a greater rate so that as the engine speed increases the plungers no longer follow paths determined by said surface so that the maximum fuel delivery of the pump decreases.

Patent ES-8403571-A1 (ES)
Title: Needle-valve injection nozzle.
IPC: F02M61/20
Filed: 1983-03-28
Abstract: A control device and method for opening and closing the nozzle of a fuel injector. The control device includes first and second cavities which are formed in the body of the fuel injector, with the second cavity being located close to the nozzle. First and second variable pressure supply chambers are connected to the nozzle and to the two cavities by several fluid passages. A spool valve and a needle valve are positioned in the first and second cavities, respectively, with the spool valve abutting a stem which projects into and terminating in the second cavity. Also situated in the second cavity between the stem and the needle valve is a spring which forms a link therebetween. The spool valve is pressure-actuated by a difference of pressure in the first and second pressure chambers to move between an open and a closed position. In the open position, fluid flow from one of the pressure chambers is permitted through the spool valve and to the second cavity. As the fluid pressure in the second cavity increases to a value greater than the compressive force of the spring, the needle valve will open and allow fluid flow through the nozzle of the fuel injector. As the spool valve moves to its closed position, it compresses the spring further and then urges the needle valve to close. The needle valve closes prior to a drop in fluid pressure in the second cavity.

Patent ES-8500466-A1 (ES)
Title: Control apparatus for a liquid flow, in particular for a radioactive liquid.
IPC: G05D7/06
Filed: 1984-03-14
Abstract: The device comprises at least one nozzle (T), in combination with a regulating valve (VR). A detector (135) measures the flowrate of the fluid in the nozzle and controls a distributor (109) for selecting a static pressure take-off orifice from among a plurality of regularly staged orifices in a convergent section (101). The orifice is brought into communication with a chamber (127) of the regulating valve to control the position of a closure member (119) which uncovers to a varying degree the orifices of a cage (117). The displacement of a distributor (121) from one position (R) to another (S) converts the regulating function into a shut-off function by pressure effect, by applying a high pressure to the chamber (127). The total immersion of the closure member obviates the disadvantages of the rod and packing system of conventional valves, as well as those resulting from the radiation-sensitivity of the prior art pneumatic servomechanisms.
Patent ES-8503622-A1 (ES)
Title: Elevator governor
IPC: G05D13/28
Filed: 1984-04-03
Abstract: A flywheel or disc rotates around a circular stationary surface, for example, a shaft, the disc is configured relative to the stationary surface so as to define the tapered area or gap at diametrically opposite positions. Two flyweights that are mounted on the disc and mechanically interconnected pivot on the disc radially outward as the disc speed increases. A pair of rollers are located in the space between the disc and the stationary surface, and, as the weights move radially outward, are progressively forced into the tapered area or gap, eventually contacting the stationary surface where they are wedged in the gap, abruptly stopping the rotation of the disc. The counterweights' center of masses and the pivot points are such that the centrifugal force of one weight is slightly greater than the other. An overspeed switch is operated by the weights at a certain speed.
