Abstract: The invention relates to a method of controlling a wind turbine, the wind turbine comprising wind turbine blades attached to a rotor hub and a control system for pitching the blades relative to the rotor hub. The method comprises determining a wind speed and providing a normal pitch mode of operation to control the output power of the wind turbine, where the pitch mode of operation comprises pitch reference values in dependence of the wind speed. The output power of the turbine is controlled according to the normal pitch mode of operation as a function of the wind speed if the wind speed is lower than a first upper level wind speed threshold, and according to a modified mode of operation if the wind speed exceeds the first upper level threshold wind speed, wherein the modified mode of operation comprises decreasing the output power according to a de-rating function which is a function of time.

Abstract: Compositions and packaging films are provided having a multilayer oxygen barrier comprising an EVOH copolymer layer in contact with at least one polyamide layer. The EVOH copolymer compositions preferably comprise about 44 mol %, or less, of ethylene. Multilayer packaging films can optionally include an exterior layer comprising heat resistant materials such as polyester or polyamide. The multilayer oxygen barriers described herein can provide high shrink films with desirably high oxygen barrier properties. The oxygen barriers can be used in making heat-shrinkable films and food packages having desirable high levels of free shrink.

Abstract: The invention pertains to a dosimeter using a canister-type irradiator having a void area adapted to contain material to be processed by irradiation and absolute dose distribution indicia which indicia comprises (i) a radiochromic, self-developing, radiation sensitive film enclosed in a radiation transmitting leak proof housing and fixedly mounted in the canister and (ii) an absolute dosage measuring amount of alanine fixedly mounted in a leak proof receptacle on the outer surface of the housing at a location overlaying said film. The invention also relates to an improved canister-type irradiator apparatus and its method of operation.

Abstract: A method of distributing or commercializing fresh meat having the general steps of butchering a slaughtered animal into a plurality of retail cuts; packaging the retail cuts into a plurality of articles wherein each article comprises a polymeric oxygen barrier film having a transparent portion in contact with at least a portion of the fresh meat product; transporting the packaged article to a retail outlet, wherein the packaged article is adapted for retail display and sale without removing the polymeric film and wherein the fresh meat product has a desirable appearance especially a desirable red color e.g. having an “a*” value of at least about 15 for the fresh beef product or of at least about 6 for a fresh pork or fresh poultry product and the color is maintained for at least five days and up to four weeks or more after display.

Abstract: Heat shrinkable, oxygen barrier, packaging films, methods of packaging and packages are provided having a myoglobin blooming agent to provide, promote, enhance or maintain a desirable coloration on the surface of a myoglobin-containing meat product.

Abstract: A coextruded heat-shrinkable, biaxially-oriented multilayered packaging film comprising a first layer, a second polymer layer, a third polymer layer, and a fourth polymer layer wherein the first polymer layer comprises a first ethylene/?-olefin copolymer preferably, an ethylene/?-olefin copolymer having an ?-olefin comprising 4-8 pendant carbon atoms, a melting point of less than 105° C., a molecular weight distribution Mw/Mn of from 0.05-2.7, a melt index of from 6.5-34 g/10 min. at 190° C., and is present in the first layer is an amount of from 50-100%, based on the total weight of said first layer. The second layer comprises a second ethylene/?-olefin copolymer having a melt index of from 0.85-6.0 g/10 min.

Abstract: A method and apparatus for the manufacture of metallic filaments is provided. The method and apparatus are used in the continuous manufacture and production of metallic filaments. The apparatus comprises a vertical reactor having a vertical chamber and having three mixing nozzles disposed at the top of the chamber and three vapor lines connecting to the respective three mixing nozzles along the axes of the nozzles, and three gas lines connecting to the respective three mixing nozzles in respective tangential directions. The apparatus also has twelve ring magnets, which are coaxially disposed, and which are mounted on the outside of the vertical ractor. The apparatus also has an outlet duct at the bottom of the chamber. The three vapor lines are supplied through three respective steam-heated heat exchangers from a feed vessel for supplying iron pentacarbonyl vapor to the mixing nozzles. The three gas lines are supplied from a nitrogen receiver tank.
