Single-primer nucleic acid amplification methods
ActiveUS20060046265A1Reduce appearanceMinimize emergenceMicrobiological testing/measurementFermentationSide productOligonucleotide
The present invention is directed to novel methods of synthesizing multiple copies of a target nucleic acid sequence which are autocatalytic (i.e., able to cycle automatically without the need to modify reaction conditions such as temperature, pH, or ionic strength and using the product of one cycle in the next one). In particular, the present invention discloses a method of nucleic acid amplification which is robust and efficient, while reducing the appearance of side-products. The method uses only one primer, the “priming oligonucleotide,” a promoter oligonucleotide modified to prevent polymerase extension from its 3′-terminus and, optionally, a means for terminating a primer extension reaction, to amplify RNA or DNA molecules in vitro, while reducing or substantially eliminating the formation of side-products. The method of the present invention minimizes or substantially eliminates the emergence of side-products, thus providing a high level of specificity. Furthermore, the appearance of side-products can complicate the analysis of the amplification reaction by various molecular detection techniques. The present invention minimizes or substantially eliminates this problem, thus providing an enhanced level of sensitivity.

Catalytic hydroconversion of chemically digested organic municipal solid waste materials
InactiveUS6270655B1Increase surface areaReduce total nitrogenLiquid hydrocarbon mixture productionHydrocarbon oil crackingParticulatesLiquid product
A hydrocarbon liquid feedstock containing at least 50 wt. % chemically digested organic-MSW material is catalytically hydroconverted utilizing either a single stage or two-stage catalytic reaction process to produce desirable lower-boiling hydrocarbon liquid products. The catalyst can be either a particulate supported type catalyst such as containing cobalt and / or molybdenum and / or nickel on alumina support, or a dispersed slurry type catalyst containing mainly iron oxide with anions of molybdate, phosphate, sulfate or tungstate, and combinations thereof. Broad useful reaction conditions are 600-860° F. (315-460° C.) temperature, 1000-3000 psi hydrogen partial pressure, and fresh feed rate of 20-60 pounds / hr / ft3 reactor volume. Effluent material from the final stage catalytic reactor is phase separated and the resulting liquid portion is fractionated to produce the desired low-boiling hydrocarbon liquid products particularly useful as transportation fuels. If desired, the chemically digested organic-MSW feedstock can be blended with petroleum residua and / or particulate coal and / or mixed waste plastics and the blended feed material processed in catalytic two-stage reactors to produce similar desirable low-boiling hydrocarbon liquid products.

The present invention relates, in general, to sheet material forming technology and the forming of structures there from. The invention relates to incremental forming of sheet material (1) with localised heating (5) and more particularly to a system and method for incrementally forming a sheet blank (1) that is at the same time heated by a dynamically moving heating source (5). This dynamic and localised heating locally changes the mechanical properties of the sheet material (1), thus facilitating the forming process.

Rinsing methodologies for barrier plate and venturi containment systems in tools used to process microelectronic workpieces with one or more treatment fluids, and related apparatuses
ActiveUS20090038647A1Rapid and efficient rinsingReduce riskHollow article cleaningElectrostatic cleaningMultiple treatmentsEngineering
Tool for treating microelectronic workpieces with one or more treatment materials, including liquids, gases, fluidized solids, dispersions, combinations of these, and the like. The invention provides an approach for rapid, efficient rinsing of wetted surface(s), and is particularly advantageous when used to rinse the lower surface of moveable barrier structures such as a barrier plate that overlies a workpiece being treated in such a manner to define a tapering flow channel over the workpiece. Rather than spray rinsing liquid onto the surface in a manner that generates undue splashing, droplet, or mist generation, the liquid is flowingly dispensed, preferably under laminar flow conditions, onto a surface that is in fluid communication with the surface to be rinsed. A smooth, uniform wetting and sheeting action results to accomplish rinsing with a significantly reduced risk of generating particle contamination.

Treatment of substrates, formation of structures, and formation of multilayer structures using contact masks are disclosed where a non-parallel or non-simultaneous mating of various mask contact surfaces to a substrate surface occurs. Some embodiments involve bringing a relative planar mask contact surface and a relative planar substrate surface together at a small angle (but larger than an alignment tolerance associated with the system). Some embodiments involve flexing a mask to make it non-planar and bringing it into contact with a substrate such that progressively more contact between the mask and substrate occur until complete mating is achieved. Some embodiments involve use of gas or liquid pressure to bow a flexible or semi-flexible mask and use a linear actuator to bring the mating surfaces together and to bring the mask into a more planar configuration.
