Patent CA-2794805-A1 (CA)
Inventor: STAMPS FRANK B
IPC: B64C11/06
Filed: 2012-11-06
Abstract: The present application includes a blade-pitch control system for controlling a pitch angle of each of a plurality of blades on an aircraft rotor. A feedback lever associated with each blade is pivotally mounted to the rotating portion of a swashplate assembly. A pitch link connects an output arm of a lever to a pitch horn of a corresponding blade, and a feedback link connects the input arm of the lever to a yoke. Flapping motion of the yoke causes motion of the feedback link, and this motion causes corresponding rotation of the lever. Rotation of the lever causes motion of the pitch link, which changes the pitch angle of the attached blade.  This provides for selected pitch-flap coupling between flapping motion of the yoke and pitch motion of the blades.

Title: Diagnostic methods for glaucoma
Inventor: GRUS FRANZ
IPC: G01N33/564
Filed: 2011-04-13
Abstract: The invention concerns a first diagnostic method for glaucoma based on an analysis of autoimmune reactivity in body fluids against at least one sample of at least partially purified ocular antigens, wherein the autoimmune reactivity against individual antigens is measured and transformed into a glaucoma score to determine the diagnostic result. Further aspects of the invention include antigen carrying elements carrying at least one sample of the at least partially purified ocular antigens and kits for diagnosis of glaucoma. Further aspects include methods of collecting a body fluid such as tears for the use in the diagnostic method for glaucoma. Yet further aspects include ocular antigens serving as diagnostic markers and/or for preparing pharmaceutical compositions for treatment of glaucoma. The invention further concerns a second diagnostic method for glaucoma comprising the steps of a) providing an in vitro culture of cells; b) incubating a body fluid from a test individual with the in vitro culture of cells or incubating components, which are fractionated from the body fluid or from a body specimen of the test individual with the in vitro culture of cells; c) analyzing protein expression of the cells and/or analyzing the viability of the cells after treatment according to step b); and d) comparing the results of the analysis in step c) with standard data to determine a diagnostic result.

Abstract: A method of biologically treating wastewater with an integrated fixed film activated sludge process. The integrated fixed film activated sludge process includes biomass suspended in mixed liquor and biomass disposed on carriers. Under certain conditions the dissolved oxygen concentration in a reactor that includes the mixed liquor, biomass suspended in the mixed liquor, and the biomass on the carriers, biological treatment is performed primarily by the biomass in the mixed liquor. This is achieved by controlling or maintaining the dissolved oxygen concentration in the reactor at a relatively low concentration. When the biomass suspended in the mixed liquor is unable to adequately biologically treat the mixed liquor, the dissolved oxygen concentration in the reactor is controlled or maintained at a relatively high concentration. This enables biomass on the carriers to contribute more to the biological treatment of the mixed liquor than when the dissolved oxygen concentration was maintained relatively low.

Abstract: A shoulder ring, for installation in a threaded pipe coupling between the installed pin ends of two pipes being connected by the coupling, has opposing end faces and a central opening, and may be lobate or circular in shape. The shoulder ring provides enhanced axial retention within the coupling by incorporating a thread element which engages the internal threads of the coupling to prevent or deter displacement of the ring from the coupling. Alternatively, enhanced axial retention may be provided by means of an interference or interlocking fit that is plastically induced during the ring installation process. The shoulder ring may be of lobate or circular configuration, with the axial retention of lobate embodiments being further enhanced by forces acting radially outward against the coupling due to elastic deformation of the ring during installation. Also disclosed are tools for installing the shoulder rings in a threaded coupling.
