  • TURBINE BLADE PLATFORM TRAILING EDGE UNDERCUT
    Publication number: 20100129228
    Abstract: A gas turbine blade having reduced stresses around a regions where the airfoil training edge joins the platform is disclosed. The lower stresses are achieved due to an undercut region proximate the blade trailing edge being placed in the platform. The undercut region has a compound fillet radius formed from two single and tangent radii where the first radius closer to the airfoil is larger than the second radius such that a ratio of R1/R2 is approximately 2.0 to 2.5.

  • Luminescent lanthanide complexes
    Patent number: 7517701
    Abstract: Systems, including compositions, kits, and methods, particularly for photoluminescence applications. The systems may include, among others, (1) organic chelators, (2) complexes between the chelators and lanthanide ions, and (3) precursors, derivatives, and uses thereof. The chelators may include a 1,4,7,10-tetraazacyclododecane ring system, for example, having the formula: Here, R1, R2, and R3 are substituents of the tetraazacyclododecane ring system, that is further substituted at the 10-position by a sensitizer Z that is typically a polyheterocyclic ring system. The organic chelator may be capable of forming a luminescent complex with a lanthanide ion, and is optionally further substituted by a reactive functional group or a conjugated substance. The resulting lanthanide complex may be useful in luminescence-based assays, such as energy transfer assays, among others.

  • Compositions And Methods Relating To Extensible Transgenic Vector Assembler, Pestilence Ridder, Plus Cannabinoid Producer
    Publication number: 20090042974
    Abstract: The following provisional patent application refers to the methods and compositions relating to a novel use for enzymatic catalysis of C21-H30-O2 (delta-nine tetrahydrocannabinol (THC)) as an insect repellent, bactericide, and fungicide and dispensation methods as commercial reagent. The bio-synthesis of cannabinoids represents a landmark achievement in the field of composting, vector removal and ecological reconstitution. Although the benefits have been known for millennia, the advent of modern bio-engineering techniques brings these small seeds of native wisdom to bear on a broader and more industrialized scale—removing dangerous molds and pestilences such as mosquitoes from swamped and flooded regions, raw sewage areas, and disaster sites where ensuing vermin and harmful vectors may cause greater damage than the initial catastrophes.
