20150056624 | METHOD FOR ISOLATING NUCLEIC ACIDS FROM A FOOD SAMPLE - The method for isolating nucleic acids from a food sample comprising the following steps: a) obtaining a food enrichment culture; b) transferring a portion of the food enrichment culture into a reaction vessel thereby providing a food enrichment sample and providing a water-immiscible phase in contact with the food enrichment culture; c) lysing the food enrichment sample to provide a lysed sample; d) isolating nucleic acids from the lysed sample. Food enrichment culture samples are known to contain high concentrations of organic and/or liposoluble inhibitors. By contacting the enrichment culture sample with a water-immiscible phase before the actual DNA extraction procedure starts, part of the lipophilic inhibitors is expected to cross the phase interface due to an enhanced solubility in the organic phase and thereby become depleted. The water-immiscible phase provided according to the invention interacts directly with the sample material throughout bacteria lysis and DNA extraction thereby optimizing the subsequent DNA purification processes due to the depletion of food-borne inhibitors. This method yields nucleic acids, in particular DNA that is of an improved quality and purity to be used in a subsequent PCR reaction to detect pathogen nucleic acids in the isolated nucleic acids. | 02-26-2015 |

20100181018 | Consolidating and Curing of Thermoset Composite Parts by Pressing Between a Heated Rigid Mold and Customized Rubber-faced Mold - Method and apparatus for consolidating and curing a composite part places and registers a composite laminate layer of thermoset polymer matrix and reinforcing fibers onto the temperature-controlled curing surface of a heated curing mold and provides a base mold with base surface covered by a rubber mask having a mask surface. Three-dimensional surfaces of the curing, base and mask surfaces complement each other so with the curing and base molds adjacent, a pressure space is formed between the base and curing surfaces that contains the compressed rubber mask, a bleeder layer for removing excess air and polymer matrix, and the composite laminate, the pressure space having a perimeter. The base and curing molds are pressed together with a particular force, thereby creating a uniform hydrostatic pressure at the rubber mask and composite laminate interface by virtue of the mold and mask three-dimensional surfaces and rubber mask thickness distribution, to squeeze the composite laminate during consolidation and curing of the part. A vacuum is also applied to the perimeter of the composite laminate during consolidation. | 07-22-2010 |

20100207305 | System for cooling shape-rolled rails - A system for cooling a hot rail of rail steel to a fine perlitic or ferritic or perlitic/ferritic structure has a plurality of separate cooling modules with independently adjustable cooling parameters. The rail is guided downstream through the modules of the cooling stretch and through intermediate zones between the modules so as to cool the surface of the rail in each of the modules and to subject the rail to destressing or stress relief between the modules. Sensors in each of the intermediate zones detect the actual surface temperature of the rail in the respective zones, and a controller connected to the modules and to the sensors varies the cooling parameters of the cooling modules in dependence on the detected temperatures in the respective upstream zones to ensure a defined temperature in the rail that lies above a critical temperature at which bainitic structure components are formed. | 08-19-2010 |
