| 20090084566 | HITCH DEVICE FOR A WORKING VEHICLE - A hitch device for a working vehicle for coupling a working device to the working vehicle has a lifting shaft unit supported in the frame structure of the working vehicle, and a coupling structure that is operatively connected therewith. The lifting shaft unit includes a lifting shaft, at least one lifting arm that is fixedly connected with the lifting shaft, and at least one reciprocating cylinder, which is hingedly connected with the lifting arm. The coupling structure includes first, upper coupling elements, which are located on the frame structure, second, lower coupling elements, which are hingedly connected to the frame structure, and connecting elements that are hingedly located on lifting arms of the lifting shaft. At least one of the connecting elements is rigid. In this manner, it is ensured that the load on the coupling elements that form the hitch device is balanced, even when a load is introduced asymmetrically. | 04-02-2009 |

| 20110261441 | Spectral Filter - This invention relates to use of metamaterials for creating spectral selectors of electromagnetic radiation. Planar metamaterial films patterned on the sub-wavelength scale can be used in polarization filters instead of natural and synthesized bulk crystals. Characteristics and the quality factor of metamaterial filters is controlled by the geometry of the pattern. Various types of metamaterials and filter configurations are proposed. | 10-27-2011 |

| 20090317544 | Method and Device for Gasodynamically Marking a Surface with a Mark - The invention relates to the field of powder materials coatings, in particular the introduction of material powder particles in a pulse mode to the surface layers of production. The invention can be used in various industries to give the surface specific physical and chemical characteristics, as well as for causing spot-markers on the surface of the production with the aim of their further identification, including new developed DNA-methods. The method proposed here is the method of causing markers on the surface Gasodynamically, which is described further: disperse gas powder dredge by supersonic gas jet in the booster channel and subsequent causing the powder from the gas powder dredge on the surface that is to be marked. At the same time the supersonic gas jet is supplied to the boost channel from the supersonic nozzle, in which the compressed gas is supplied from the source of gas. Gas powder dredge is fed to the booster channel from the ejection chamber in the form of a swirl through the annular gap formed by external surface of the supersonic nozzle and internal surface of the ejection chamber. Also the device for causing spot-markers on the marking surface Gasodynamically, which is proposed, is also described further: boost channel and ejection chamber are coaxial and conjugated hermetically and in the place of this conjugation, the inner surface of this conjugation forms annular gap with outer surface of supercritical part of supersonic nozzle, powdered material batcher formed by sectional and hermetically conjugated case and lid, and inside it is fitted with U-shaped curved tube performed as split through U-shape curve and fitted with aperture in the area adjacent to the inner part of the lid. | 12-24-2009 |
