Abstract: A surgical clamp for providing a stable mechanical grasp and stabilisation of bone during an orthopaedic surgical procedure, comprising: a first arm comprising: an extended section comprising a mount at the distal end thereof; and a first jaw portion located at the distal end of the first arm; a second arm comprising: a fastening platform located at the proximal end of the second arm; and a second jaw portion located at the distal end of the second arm; engagement means comprising a bolt to engage the first arm with the second arm about a pivot point formed by the engagement means to provide relative rotation of the first and second arms between: an open configuration whereby first jaw portion and second jaw portion are urged apart; and a clamped configuration whereby first jaw portion and second jaw portion are urged into clamping engagement with the patient's bone in use during the surgical procedure; a fastening component comprising a fastening bolt and a fastening nut, adapted to engage the first and seco

Abstract: A system and method are provided for controlling the power setting of an aircraft engine when the current height-above-terrain (HAT) value Hc is less then a predetermined minimum H(min). The system includes a ground proximity unit (GPU) for measuring Hc, one or more sensors coupled to the engine for detecting an out-of-range operating condition of the engine, an engine control unit (ECU) coupled to the GPU and the one or more sensors and the engine, for controlling operation of the engine in response to Hc, H(min) and the engine operating values. When the one or more sensors detects an out-of-range operating condition normally curable by reducing the engine power setting, the ECU is prevented from automatically reducing the power setting of the engine if Hc<H(min). No pilot action is required.

Abstract: To facilitate the collection of grease and water from commercial kitchen exhaust fans the invention provides a collection tank in communication with the drainage spout of the fan assembly. The tank has a lid for sealing the tank, a first reservoir for collecting the stream of grease and water and a second reservoir below the first reservoir for receiving water separated from the grease and water stream in the first reservoir. The first and second reservoirs are separated by a sloping plate. The tank also includes a siphoning apparatus which when connected to a source of high pressure fluid such as water or steam can purge the second reservoir of water and recycle the water back to a fan cleansing operation or to a disposal facility.

Abstract: Low dielectric materials and films comprising same have been identified for improved performance when used as performance materials, for example, in interlevel dielectrics integrated circuits as well as methods for making same. In one aspect of the present invention, the performance of the dielectric material may be improved by controlling the weight percentage of ethylene oxide groups in the at least one porogen.

Abstract: This invention relates to an improvement in a deposition process for producing low dielectric films having a dielectric constant of 3, preferably <2.7 and lower. The process comprises the steps: (a) forming a liquid precursor solution comprised of an organosilicon source containing both Si—O and Si—C bonds and solvent; (b) generating a liquid mist of said liquid precursor solution, said mist existing as precursor solution droplets having a number average droplet diameter size of less than 0.5 ?m; (c) preferably electrically charging the liquid mist of said liquid precursor solution droplets; (d) depositing liquid mist of said liquid precursor solution droplets onto a substrate; and, (e) converting the thus deposited liquid mist of said liquid precursor solution droplets to a solid, low dielectric film.

Abstract: The invention provides methods, systems, and products for communicating between engine computers without the participation of a flight deck computer. The invention allows the engine computers to coordinate activities for real-time control of the engines for improved efficiency using an existing ARINC 429 communications bus. The invention facilitates cross-engine communications over the same ARINC 429 communications bus used for communicating with the Flight Deck Computer, without installation of a second, dedicated communications bus for cross-engine communications. The invention thus provides a cost effective way to allow the engines to coordinate activities without expensive installation and recertification of airframe modifications.
