| 20080316777 | Method for thermal protection of frequency converter and a frequency converter - A method for thermal protection of a frequency converter and a frequency converter that comprises means for controlling the output current of the frequency converter. The method comprises the steps of determining beforehand two or more data points which define a thermal current limit for a semiconductor component of the frequency converter at specific temperatures at two or more switching frequencies, determining beforehand two or more data points which define a thermal current limit for the semiconductor component at specific temperatures at a zero converter output frequency, measuring the temperature of the semiconductor component, determining the switching frequency of the frequency converter, determining the output frequency of the frequency converter, determining the highest allowable thermal current as a function of measured temperature, determined switching frequency and determined output frequency on the basis of the defined data points, and limiting the output current of the frequency converter to the determined highest allowable thermal current. | 12-25-2008 |

| 20090074964 | METHOD AND APPARATUS FOR REMOVING SUBSTANCES FROM GASES - The present invention concerns a method and an apparatus for removing substances from gases discharged from gas phase reactors. In particular, the invention provides a method for removing substances contained in gases discharged from an ALD reaction process, comprising contacting the gases with a “sacrificial” material having a high surface area kept at essentially the same conditions as those prevailing during the gas phase reaction process. The sacrificial material is thus subjected to surface reactions with the substances contained in the gases to form a reaction product on the surface of the sacrificial material and to remove the substances from the gases. The present invention diminishes the amount of waste produced in the gas phase process and reduces wear on the equipment. | 03-19-2009 |

| 20100316186 | Arrangement and Method in Digital Mammography Imaging - The invention relates to an arrangement and method in digital mammography imaging especially for use for imaging of small breasts. In the invention, a so-called full-field sensor and an upper compression plate substantially equal in width with this sensor are used. According to the invention, the beam is limited to a width narrower than the width of the sensor and the compression plate and directed for oblique imaging non-centrally relative to the center of said sensor and the upper compression plate, while the automatic exposure system of the imaging apparatus is caused to adapt itself for imaging in accordance with this imaging position non-central relative to the sensor and the upper compression plate. | 12-16-2010 |

| 20100209725 | METHOD OF MODIFYING PAPER AND CARDBOARD - A fibrous product, the absorption and desorption properties of which have been improved and which comprises a fibrous substrate which has, on at least one of it surfaces, a small quantity of a modified starch, and a method of producing it. According to the present invention, onto at least one surface of the fibrous product is applied 0.01-1.0 g/m | 08-19-2010 |
| 20100261807 | NOVEL DISPERSIONS AND METHOD FOR THE PRODUCTION THEREOF - An aqueous dispersion comprising a non-settling colloidal hemicellulose ester polymer in water and a method of producing the same. In the method an esterified hemicellulose is provided wherein at least a part of the esterifying groups are derived from a lower alkanoic acid; the esterified hemicellulose is dissolved in an alkanoic acid to produce a solution; and the solution is dispersed into water to produce an aqueous dispersion of the hemicellulose ester. The present compositions, containing hemicellulose derivatives of low solubility, can be used in paper, paperboard and other fibre-based materials, for paints, surface treatments for polymer films, and polymer films as such, and can be applied as binders. | 10-14-2010 |
