Inventor: NOLL ROBERT
IPC: G01N21/27
Filed: 2011-02-25
Abstract: A method is provided that includes receiving and processing a sample signal scan.  Processing the sample signal scan includes applying an inner-product operation on the sample signal scan and each of a plurality of eigenvectors to generate a plurality of corresponding coefficients, and subtracting the sample signal scan from a linear combination of the eigenvectors and corresponding coefficients to thereby produce a corrected sample signal scan. In this regard, the eigenvectors have been generated by decomposing a plurality of background reference signal scans according to a singular value decomposition technique. The signal scans include a plurality of electromagnetic signal measurements at a discrete set of frequencies, where each measurement has been taken by a spectrometer system passing an electromagnetic signal through a sample cell including just a base medium (for the background reference signal scans), or both a base medium and a sample medium (for the sample signal scan).

Abstract: An alcohol dehydrogenase (ADH) from hyperthermophilic archaeon Thermococcus guaymasensis was purified to homogeneity and was found to be a homotetramer with a subunit size of 40 ~ 1 kDa. The gene encoding the enzyme was cloned and sequenced, and found to have significant sequence homology to known zinc-containing ADHs and L-threonine dehydrogenases with both binding motifs of catalytic zinc and NADP+. The wild-type enzyme is a primary-secondary ADH that exhibits a substrate preference for secondary alcohols and corresponding ketones, and exhibits unusual stereoselectivity.    The wild-type enzyme was found to have outstanding thermostability, demonstrating 60% activity after incubation at 80°C for 40 hours. Site-directed mutagenesis was used to substitute the cyteine residue at position 56 with a serine, to provide the TgADH(C56S) mutant. In the assays that we carried out, we found virtually no difference in enzyme activity and oxygen-sensitivity between the mutant TgADH (C56S) and wild type TgADH.

IPC: C23C14/16
Filed: 2010-02-04
Abstract: The present disclosure concerns a process suitable for coating discrete articles with a zinc-rich, fully alloyed layer.  A known method for the corrosion-protection of such articles comprises the steps of hot-dip galvannealing, typically followed by painting. This hot-dip process has however to be performed at a high temperature, thereby submitting the articles to severe thermal stress. A novel vacuum deposition process of Zn is therefore presented. It is characterized in that, in the step of contacting the arti-cle with metallic Zn vapor, the temperature of the article is equal to or higher than the dew point of the Zn vapor. The process results in a coating having a uniform thickness, even on less accessible surfaces. The surface roughness is well adapted for the adhe-sion of paint.

Abstract: The present disclosure is directed to a process for the chemical syn-thesis of (-)-.DELTA.9- ^tetrahydrocannabinol (.DELTA.9--THC) and related compounds of formula (I). In particular, the process comprises a one-pot condensation and sulfonylatton re-action sequence that produces crude .DELTA.9--THC aryl sulfonate or related compounds. Sulfo.pi.ylatio.pi. of .DELTA.9-THC or related com-pounds immediately upon their formation imparts stability to the cannabinoids, and prevents formation of the corresponding .DELTA.8 isomer. .DELTA.9THC aryl sulfonates may be readily separated from A6THC aryl sul-fonates using reverse phase chromatogra-phy. Hydrolysis of the .DELTA.9-THC aryl sul-fonates or related compounds produces .DELTA.9--THC or related compounds containing rel-atively low amounts of the corresponding .DELTA.8 isomer. (Formula I).

Abstract: A structure includes a skin and a foam member. The foam member has a molded contour, the mold contour being configured to provide tooled surface for the skin. When the skin is a composite skin, the foam member provides support for the skin so that the skin can be cured under heat and pressure. A method of making the foam member for a foam stiffened structure includes creating a mold having an interior cavity which resembles a desired shape the foam member. A subsequent step involves introducing a foam mixture into the mold. Next, the foam mixture is allowed to polymerize so as to expand and distribute within the cavity of the mold. The method further includes selectively controlling a density of the foam member in the mold. The foam member is at least partially cured. The foam member is assembled with a skin to produce the foam stiffened structure.

Abstract: A device used for the prevention of property damage or personal injury due to a motorcycle falling over when parked on unsuitable ground. Unsuitable ground includes but is not limited to:  wet, muddy, grass covered, rocky or sandy soil, or asphalt in direct sunlight.  The device utilizes redistribution of weight over a larger area to increase the amount of supportable weight. This device nicknamed "motorcycle landing" consists of two parts. These parts attach to the bike frame, tank or other area via magnetism or other means. The device is removed and placed under the kickstand when parking. This increases the surface area and the amount of supportable weight and thus renders poor ground suitable for parking heavy motorcycles safely.  Also, the device is designed in such a way to enhance the motorcycles appearance.
