Granted: 2009-12-08
Abstract: A torque tube and conical back plate for aircraft brakes including a torque tube having a truncated back plate of thin metal construction extending from the outboard end thereof. The conical back plate is characterized by inner and outer reinforcing rings, such rings providing a compressive force at opposite ends of the truncated cone of the back plate, thus allowing the back plate to resist bending and deflection. In accordance with the invention, the cross sectional centers of mass of the inner and outer reinforcing rings are shifted outboard from a projection of the center plane of the conical back plate, such positioning enhancing the stiffening and reinforcing capabilities of the reinforcing rings.

Abstract: L'invention concerne un procédé pour solubiliser et purifier des protéines recombinées qui sont exprimées dans des cellules hôtes bactériennes et sont déposées en tant qu'agrégats non solubles ( corps d'inclusion). La purification s'effectue par transformation des corps d'inclusion en formes solides au moyen de réactifs de dénaturation organiques et par mise en oeuvre de procédés chromatographiques. A cet effet, on sélectionne des phases mobiles inorganiques, alcalines et renfermant des sels, qui permettent, une fois la purification effectuée, de mettre à disposition les protéines recombinées, après neutralisation, sous une forme physiologiquement tolérable et directement utilisable en médecine. Ce procédé est particulièrement approprié pour la purification d'allergènes et de fragments de ces derniers.

Abstract: A short range radiolocation system and associated methods that allow the location of an item, such as equipment, containers, pallets, vehicles, or personnel, within a defined area. A small, battery powered, self-contained t ag is provided to an item to be located. The tag includes a spread-spectrum transmitter that transmits a spread-spectrum code and identification information. A plurality of receivers positioned about the area receive signals from a transmitting tag. The position of the tag, and hence the item , is located by triangulation. The system employs three different ranging techniques for providing coarse, intermediate, and fine spatial position resolution. Coarse positioning information is provided by use of direct- sequence code phase transmitted as a spread-spectrum signal. Intermediate positioning information is provided by the use of a difference signal transmitted with the direct-sequence spread-spectrum code. Fine positioning information is provided by use of carrier phase measurements. An algorithm i s employed to combine the three data sets to provide accurate location measurements.

Abstract: This invention teaches a rope that can be electrified. The rope is comprised of an outer sheath and an inner core. The outer sheath includes non-conductive elements braided with one or more conductive elements. The conductive elements are wound in a parallel helical pattern and do not touch each other. The inner core is a braid comprising non-conductive and conductive elements. In both cores, the conductive elements comprise one or more metal strands and the non-conductive elements comprise one or more monofilaments of synthetic or natural fibres. Should a breakage occur in the conductive elements of the outer sheath, the conductive elements of the inner core provide conductivity across the breakage and throughout the length of the rope by intermittently contacting the conductive elements of the outer sheath. An optional coloured tracer can be braided into the outer sheath to provide better visibility since the non-conductive elements are preferably a neutral colour, such as white.
