The supply includes a cooled case beam that is hollow inside and several nozzles for feeding the additional material. | 08-06-2009 |
20100319782 | Method For Monitoring The Composition Of Flue Gas Resulting From A Thermal Process - The composition of flue gas generated in a thermal process, especially in the combustion of bio fuel or refuse-derived fuel, is monitored by measuring the quantity of particles belonging to certain size categories in at least one point along the flow path of the flue gas. Such particle size categories are chosen as objects of the measurement, in which the particles are known to consist mainly of alkali chlorides. | 12-23-2010 |
20150138544 | MEASUREMENT OF GASEOUS COMPOUND USING SPECTROSCOPY - The method includes guiding a light beam to a first optical path, the light beam being attenuated to an attenuated light beam and detecting a first value indicative of a first intensity of the attenuated light beam. The method further includes generating a last light pulse, dissociating at least part of the gas compound molecules (optionally excited) or dissociated parts thereof (optionally excited) on the first optical path to first part atoms, molecules, ions, or radicals, and to another part using the last light pulse, the light beam being further attenuated by absorption to the first part atoms, molecules, ions, or radicals on the first optical path. The method further includes detecting a second value indicative of a second intensity of the attenuated light beam and determining, using the first and second values, the gas compound content of the gas mixture. A gas compound measuring device measures uses the method. | 05-21-2015 |

The power semiconductors and the cooling elements are disposed around a center axis of the arrangement in such a manner that they demark a channel around the center axis from at least three sides, to which channel cooling surfaces of the cooling elements extend and in which the cooling medium is able to flow in the direction of the center axis, and the power semiconductors extend from the connections between the power semiconductors and the cooling elements substantially away from the center axis. The arrangement can further include at least one choke disposed in the channel demarked around the center axis. | 09-16-2010 |
20100265659 | ELECTRIC DRIVE - An electric drive is disclosed which includes at least a choke unit, a power step unit, and a capacitor unit for implementing power supply to an electricity-consuming device. A cooling arrangement is disclosed for cooling the choke unit, the power step unit, and the capacitor unit. The choke unit, the power step unit, and the capacitor unit can be distributed into at least two separate and separately coolable entities, and the cooling arrangement can include parallel cooling apparatuses for cooling the at least two separate and separately coolable entities. | 10-21-2010 |
20120257338 | FREQUENCY CONVERTER UNIT - A frequency converter unit includes a unit body, input bus bar means and output bus bar means. The input bus bar means have a plurality of input side bus bars spaced apart in a first direction, and the output bus bar means have a plurality of output side bus bars spaced apart in the first direction, which is perpendicular to an installation direction of the frequency converter unit. Each of the plurality of input side bus bars and the plurality of output side bus bars includes an aperture configured to connect the bus bar to a counterpart contact in a frame with a bolt-nut connection. | 10-11-2012 |
20150359143 | METHOD OF HEAT TRANSFER IN POWER ELECTRONICS APPLICATIONS - An exemplary method of heat transfer in power electronics applications is disclosed, wherein a metal foil including at least about 50% of tin, based on a total amount of metals contained in the metal foil, is used as a thermal interface material between a base plate of a heat-generating component and a heat sink. The metal foil is disposed on a heat sink. A base plate of a heat generating component or module is disposed on the heat sink covered by the metal foil to provide a power electronics device. A clamping force is applied to the power electronics assembly to provide a cooled power electronics assembly. | 12-10-2015 |
