Abstract: Described is a turbine arrangement of a gas turbine engine, the turbine comprising: a rotor comprising a disc which incorporates a plurality of circumferentially spaced turbine blades, each blade having an aerofoil extending for a platform and a root portion securing the blade to the disc, a lock plate located at an axial end of the root portion of the blade, the lock plate comprising: a plate body having an inward facing surface which is located adjacent the blade root and an outward facing surface, radially inner and outer edge portions, and first and second circumferential edges; a head located at the radially outer edge portion of the plate body; a foot portion located at the radially inner portion of the plate body; a projection extending from the outwardly facing surface away from the turbine blade root in use, the projection being located adjacent to the foot portion, wherein the foot portion and head portion are located within slots provided at least partially by the disc and turbine blade respectivel

Abstract: A turbine blade includes a labyrinth of internal channels for the circulation of coolant received through an inlet formed in a terminal portion of the blade root and leading to a duct-defined wall. A first passage intersects the duct and extends through the blade towards a tip. An end of the first passage is arranged to capture incoming coolant flow. A second passage intersects the duct at a position downstream of the first passage intersection. The duct and/or the passage intersections are configured to create a pressure drop in the duct in the direction from the inlet to the second passage intersection. In an axial direction, a duct wall terminates at a position between the inlet and the second passage intersection.

Abstract: A turbine stage assembly includes a disc carrying a cascade of blades and an annular seal-plate that is secured to the disc by a first connection. One or more of the blades include a root portion configured to be received in a complementarily shaped radially extending slot in the disc such that a face of the root portion faces the plate. A terminal portion of the root portion is cut away adjacent the face to present an open space between a radially inner wall of the slot and a wall of the cutaway root portion. A first part of a second connector extends radially inwardly from the wall of the cutaway root portion. The first part of the second connector is configured to engage with a complementing second part of the second connector provided on the seal-plate.

In an axial direction, a duct wall terminates at a position between the inlet and the second passage intersection to balance the pressure of coolant in the duct with the pressure of coolant in a leakage path thereby reducing the mass flow of coolant entering the leakage path.

Abstract: A turbine blade has a trailing end and a leading end and a tip. A gutter is formed in the tip and extends to an exit defined in a region of the trailing end of the blade. The gutter is defined at least in part by a floor, and the floor defines a decreased depth in a region proximal to the exit than in a region distal to the exit.

Abstract: Devices systems and methods are provided for providing a deterministic remote interface unit (RIU) based on a finite state machine. The RIU emulator uses a sequence controller that is configured to receive a synchronization input and to execute a fixed list of unconditional commands in an invariable order of execution based solely upon the synchronization input. The RIU emulator also uses pre-defined or pre-certified data structures that are specific to one or more interface devices to successfully execute the at least one unconditional command of the plurality when encountered in the invariable order. As such, peripheral devices may be added, removed or updated without recertification by merely inserting pre-certified data structures into memory or deleting them.

Abstract: A method of thermally treating tissue during a surgical procedure where a surgical access device, including a body member having walls with at least one conduit therein, is inserted into the patient. A chilled fluid is circulated through the at least one conduit such that the tissue that is located proximate the body member is cooled. Alternatively, the body member may be constructed from a highly thermally conductive material such that heat energy is transmitted through the body from the tissue located proximate the body member and into a heat sink. The surgical device may include a first or second blade portions constructed from an inner and an outer shell having walls. Ribs located on the inner shell sealingly coupled to the inner wall of the outer shell to create the at least one conduit within the walls of the blade portion.

Abstract: A hinge set (and associated methodology and resultant hung doors or windows) where the leaf of each hinge sleeved component is, or is to be, leafwise received in, and is, or to be, screwed into, a different cavity, yet allowing aligned sleeve meshing for pin insertion. Its use allows the leaf to be largely concealed even when the doors or windows are open.

Abstract: A device for spinal stabilization includes bone anchors, a metal cord, and a spacer. The materials of the cord and spacer are chosen to allow the physician to customize the stiffness of the stabilization device based on a particular patient's needs. Each bone anchor has a clamping mechanism for securing the cord to the bone anchor. In an assembled and implanted state of the device, the spacer is positioned between two neighboring bone anchors, thereby impeding the motion of the bone anchors toward each other; the cord is clamped to the bone anchors, thereby impeding the motion of the bone anchors away from each other. By increasing or decreasing the tension in the cord during implantation, the physician can create a stabilization device that is either relatively stiff or relatively flexible to accommodate the specific needs of the patient.

Abstract: An instrument, and method for using the same, for treating and repairing a vertebral body, which includes a steerable shaft and a distal end portion. The steerable shaft defines a longitudinal axis and includes a proximate portion and a flexible portion along the length. The distal end portion extends from the steerable shaft with an initial diameter, in the collapsed state, and has one or more expanded diameters. After inserting the instrument into the vertebral body, the flexible portion permits the distal end portion of the steerable shaft to be steered away from the longitudinal axis toward a center region within the vertebral body. A cutting surface upon the distal end portion is used to ream cancellous bone within the vertebral body and to create a single void which is off-set form the initial access axis.

Abstract: The present disclosure provides methods for the transformation of soybean cells or tissue and regeneration of the soybean cells or tissue into transformed plants. The disclosed methods utilize an explant prepared from an immature soybean seedling which can be induced directly to form shoots that give rise to transgenic plants via organogenesis. The disclosed methods do not require germination and are rapid and efficient.
