Abstract: The present invention relates to a bone plating system and method for fracture fixation of bone. The bone plating system includes a bone plate, at least one locking screw, and at least one non-locking screw. The bone plate has locking holes with threads and non-locking holes. The locking screws have a shaft with a thread for engaging bone and a head with a thread configured and dimensioned to mate with the thread of the locking holes. The non-locking screws have a thread for engaging bone and a non-threaded head. Both the locking and non-locking screws remain seated in their respective holes for substantially as long as the bone plate is implanted. The non-locking screws compress the bone plate against the bone and hold fracture reduction while the locking screws are secured to the plate at a fixed angular relationship. The mixed fixation achieved by this bone plating system and method is particularly useful for treatment of per-articular fractures.

Abstract: A binder mechanism comprises a pair of prong plates pivotally connected by a retainer spring to toggle between a first raised position and a second lowered position. The prong plates include a plurality of ring segments affixed to the prong plates that are capable of forming loops. A cam mechanism is used to toggle the prong plates between the raised and lowered positions causing the ring segments to open or to close to form loops. The cam mechanism is preferably a slider located above the prong plates, the slider having ramps inserted through recesses between the prong plates. Preferably, the recesses are located adjacent to where the ring segments are attached to the prong plates. Cleats may hold the parts of the binder mechanism together and keep the mechanism attached to a binder assembly. Preferably, the retainer spring is in the form of a top spring covering both the slider and prong plates. A handle may be attached to both the top spring and slider such that when the handle is pivoted it moves the slider longitudinally away from the handle causing the ramps to contact the prong plates adjacent the recesses resulting in the prong plates moving upward or downward to open or close the ring segments to form loops.

Abstract: A transition duct for routing a gas flow from a combustor to the first stage of a turbine section in a combustion turbine engine has an internal passage from an inlet to an outlet that is offset from the inlet in the longitudinal, radial and tangential directions. The offset outlet and the curved internal passage discharge the gas flow toward the first stage blade array at an angle in the tangential direction relative to the longitudinal direction. This angled discharge can be presented directly to the blades, thus avoiding the need for first stage vanes and the associated costs and complexity.

Abstract: Aspects of the invention relate to a turbine engine system and method for actively managing blade tip clearances during part load operation of the engine. Aspects of the invention relate to extracting a portion of the combustion gases from the combustor section of the engine and routing these heated gases to the blade rings or other stationary structure surrounding the turbine blades. Upon exposure to the combustion gases, which can be mixed with compressor exit air, the stationary structure will thermally expand, causing blade tip clearances to increase. Thus, concerns of blade tip rubbing are minimized. Once the engines achieves steady state operation, the flow of the combustion gases to the blade rings can be substantially restricted so that only compressor exit air is supplied to the stationary structure. Consequently, the stationary structure will contract and the blade tip clearances will decrease, thereby increasing the efficiency of the turbine.

Abstract translation: 本发明的方面涉及一种用于在发动机的部分负载运行期间主动地管理叶片顶端间隙的涡轮发动机系统和方法。 本发明的方面涉及从发动机的燃烧器部分提取一部分燃烧气体并且将这些加热的气体引导到围绕涡轮机叶片的叶片环或其它静止结构。 当暴露于可与压缩机出口空气混合的燃烧气体时，固定结构将热膨胀，导致叶片尖端间隙增大。 因此，叶片尖端摩擦的问题被最小化。 一旦发动机达到稳态运行，燃烧气体到叶片环的流动可以被大体上限制，使得只有压缩机出口空气被供应到固定结构。 因此，固定结构将收缩并且叶片顶端间隙将减小，从而提高涡轮机的效率。

Abstract: A pontoon comprising a seamless, non-woven, one-piece, inflatable vessel preferably formed by a process of rotational molding, from a resilient, semi-rigid polyolefin elastomer, preferably metalocene. The pontoon has shape memory characteristics, which make it partially self-inflating, and cause it to entrap air when partially deflated, to thereby resist complete deflation if punctured, allowing a user to more easily get to safety. Punctures in the pontoon may be easily eliminated by applying heat to the polymer material at the site of the puncture, such as with a hot knife or other metal implement, so as to fuse the polymer material together. The bottom of the pontoon is preferably thicker than the top, and the ends of the pontoon taper to a blunt point that is thicker still, to thereby resist damage from impact and to help maintain the desirable shape-memory characteristics of the pontoon. The pontoon is tolerant of significant relative pressure changes without substantial deformation or change in its shape.

Abstract: A digital communications system efficiently transports communications data in ATM format from a plurality of information providers to a plurality of users, maximizing transport of the supply of ATM streams to distribution paths in a network. A video tone dial network arrangement synchronizes the timing among various VIP source multiplexers and super trunk transmitters. ATM streams are transported through an ATM backbone network and a local loop distribution network. A serving node, or host digital terminal, of the local loop distribution network, supplies the bit stream carrying ATM cells for a video program to the user terminal and provides information necessary to permit the terminal to decode the data from the ATM cells carrying the program information.

Abstract: Aspects of the invention relate to methods and assemblies for improving the efficiency of a turbine engine through active management of blade tip clearances. In some designs, a portion of compressor exit air is routed to the rotor and discs of the turbine section. Aspects of the invention relate to treating the compressor exit air in light of the operating conditions of the engine. For instance, under base load or substantially steady state operation, a portion of compressor exit air can be routed to the rotor and discs without reducing the temperature of the compressor exit air. In such case, blade tip clearances will reduce, allowing for improved engine efficiency. Under part load or substantially transient operating conditions, a portion of compressor exit air can be cooled before it is supplied to the rotor and discs. As a result, the blade tip clearances increase, minimizing concerns of blade tip rubbing. Routing of the compressor exit air for cooling and bypass can be controlled by a valve.
