Abstract:
A filter formed essentially from a staple fiber is provided. A nonwoven staple fiber is compressed in to a mat or sheet of selected porosity. The mat or sheet does not include a binder or bicomponent fibers. The staple fibers may be heat treated. The sheet is formed into a selected geometric shape and the staple fibers are thermally fused to bind the staple fibers into a porous filter element. The preferred shape is a helically wound tube or plural sheets, each sheet being self-overlapped and compressed to overlap another sheet. Each sheet is preferably heated and compressed individually and the sheets may be selected to have different porosities and densities.
Abstract:
A method for the characterization of chromosomal inversions using anti-parallel probes is described. Reporter species are attached to oligonucleotide strands designed such that they may hybridize to portions of only one of a pair of single-stranded sister chromatids which may be prepared by the CO-FISH procedure. If an inversion has occurred, these marker probes will be detected on the second sister chromatid at the same location as the inversion on the first chromatid. Further, one or more reporter species are replaced with anti-parallel probes that hybridize at known locations along the second sister chromatid such that the position and size of the inversion may be identified/estimated.
Abstract:
Turbine blade assemblies of a turbine include airfoils that are mounted on bases. The leading and/or trailing edges of the bases are provided with curved portions. Likewise, curved portions may be provided on leading and/or trailing edges of the angle wings of a turbine blade assembly. Also, curved portions may be provided on the leading and/or trailing edges of nozzle assemblies of a turbine.
Abstract:
This application relates to hardware based memory scrubbing. One disclosed embodiment may comprise a system that includes an engine, implemented in hardware, configured to initiate a request for data residing in associated memory. An error system is configured to detect errors in data that has been read from associated memory in response to the request for the data, the error system maintaining a log of entries corresponding to errors detected by the error system. An identifier is associated with each of the entries in the log that result from the request initiated by the engine to differentiate from other entries in the log.

Abstract:
A communication device (100, 200) is adapted to participate in a primary communication on a communication channel with at least one other communication device (250); and simultaneously transmit an image to the at least one other communication device (250) or and alternative communication device using the communication channel or an alternative communication channel.
Abstract:
The present invention is directed to accounting for crystal cut error data in ion implantation systems, thereby facilitating more accurate ion implantation. One or more aspects of the invention also consider possible shadowing effects that can result from features formed on the surface of a wafer being doped. According to one or more aspects of the invention, crystal cut error data and optionally feature data also are periodically fed forward in one or more ion implantation stages or systems to ascertain how to re-orient the ion beam with respect to the workpiece to achieve desired implantation results.
Abstract:
Method and apparatus for introducing particles into living cells. Fluorescently-stained human chromosomes are introduced into cultured, mitotic Chinese hamster cells using electromicroinjection. The recipient cells frequently survived the physiological perturbation imposed by a successful chromosome injection. Successfully injected recipient cells maintained viability as evidenced by their ability to be expanded.The technique relies on the surface charge of fluorescently stained chromosomes and their ability to be attracted and repelled to and from the tip of a micropipette. The apparatus includes a micropipette having a tip suitable for piercing the membrane of a target cell and an electrode inserted into the lumen thereof. The target cells and suspended particles are located in an electrically conducted solution, and the lumen of the micropipette is filled with an electrically conducting solution which contacts the electrode located therein. A second electrode is also located in the conducting solution containing the target cells and particles. Voltages applied to the electrode within the micropipette attract the particles to the region of the tip thereof. The particles adhere to the surface of the micropipette with sufficient force that insertion of the micropipette tip and attached particle through the membrane of a target cell will not dislodge the particle. By applying a voltage having the opposite polarity of the attraction voltage, the particles are expelled from the micropipette to which is then withdrawn from the cell body.
Abstract:
A system for cleaning at least one filter in a baghouse and an associated method for providing the system. The at least one filter separate a dirty gas chamber from a clean gas chamber, and filters at least one substance from a gas. The system includes a supply of compressed air and a blowpipe to direct the air at the at least one filter to dislodge a collected amount of the at least one substance from the at least one filter. The blowpipe has a cross-sectional flow area through which the compressed air flows. A valve controls provision of the compressed air. The valve has a cross-sectional flow area though which the compressed gas flows. The cross-sectional area of the valve is smaller than the cross-sectional area of the blowpipe to provide for air pressure at the valve to be greater than air pressure at the blowpipe.
Abstract:
A method and a kit for the identification of chromosomal inversions is described. Chromosomal inversions are difficult to detect unless they are quite large. The improved ability to detect chromosomal inversions is important to a number of medical applications, such as cancer and birth defects, as examples. Reporter species are attached to oligonucleotide strands designed such that they may hybridize to portions of only one of a pair of single-stranded sister chromatids prepared by the CO-FISH procedure, as an example. If an inversion has occurred, these marker probes will be detected on the sister chromatid at the same location as the inversion on the first chromatid.
