摘要： A method for delivering liquid fuel and gaseous fuel to a dual fuel engine operating in a dual fuel mode includes establishing a governor output value indicative of a total fuel energy rate desired to be delivered to the engine to maintain a desired engine speed. A first value indicative of a liquid pilot fuel energy rate desired to be delivered to the engine and a second value indicative of a gaseous fuel energy rate desired to be delivered to the engine are each determined such that the sum of the desired liquid pilot fuel energy rate and the desired gaseous fuel energy rate is substantially equal to the desired total fuel energy. A stored gaseous fuel energy content can be updated to assure continued accuracy of the fuel control system of the dual fuel engine.

摘要： A method and a tool for tying a stitch knot. The tool comprises a first elongated member and a grasping member. The first elongated member includes a helix on one end. The helix has a filament extending from the first end, and a threading device is attached to the free end of the filament. The grasping member is separate and apart from the first elongated member, and includes an elongated shaft. A grasper is mounted on the first end of the shaft, and a portion of the shaft near the grasper is sized to reside within the helix for axial movement therewith. The method for tying the stitch knot involves positioning the shaft within the helix. The grasper is used to insert the threading device and pull the free end of the filament through an area to be stitched, and then to grasp the free end of the filament near the threading device. The grasping member is removed from the inner space of the helix, thus drawing the free end of the filament through the helix. When the grasping member and helix are moved apart from each other and the filament is removed from the helix, a loop for the stitch knot is formed. Moving the grasping member and helix further apart tightens the loop to the area to be stitched.

摘要： An apparatus for use in an arrangement for measuring the relative position of two bones during surgery includes a clamp and a measurement arm. The clamp is adapted to engage and secure to an anchor in a fixed vertical position, the anchor being secured to a first bone location. The measurement arm comprises an elongate portion and a locator portion that extends angularly from the elongate portion. The measurement arm is slidably supported on the clamp. The measurement arm is further rotatably supported on the clamp at a position in which an axis of rotation of the measurement arm is spaced apart from a longitudinal axis of the anchor.

摘要： A method for transitioning between a first operating mode of a dual fuel engine and a second operating mode of the dual fuel engine includes establishing a final liquid fuel amount desired to be delivered to the engine upon completion of the transition to the second operating mode. Delivery of liquid fuel to the engine is adjusted by a first amount and, correspondingly, delivery of gaseous fuel to the engine is adjusted by a second amount, where an energy content of the first amount of liquid fuel is substantially the same as an energy content of the second amount of gaseous fuel. A determination is made as to whether liquid fuel is being delivered to the engine in an amount which is substantially the same as the desired final liquid amount previously established. The fuel adjustment step and the determination step are repeated until a determination is made that liquid fuel is being delivered to the engine in an amount which is substantially the same as the desired final liquid fuel amount, at which point the transition is considered complete.

摘要： In one embodiment of the present invention an apparatus for controlling one or more engines by synchronizing the functions of two or more electronic control modules includes a master electronic control module, one or more slave electronic control modules, and one or more data links for transferring data between the electronic control modules. Engine control and monitoring functions are divided between the master electronic control module and the slave electronic control modules. The present invention may be used to control and monitor dual fuel engines and engines that operate on one type of fuel. The master electronic control module may transition operation of the engine to the diesel fuel only mode in the event of a failure of any dual fuel mode specific components. The master ECM coordinates timing and speed of fuel injection to engine cylinders using input from an adjustable engine speed command device and a speed sensor connected to each engine. The loads driven by the engines may be allocated evenly or unevenly.

摘要： A method of detecting leakage through a gaseous fuel admission valve of a dual fuel engine including at least one such gaseous fuel admission valve and a gaseous fuel shut off valve includes determining a liquid fuel rate when the engine is operating in a liquid fuel mode and the gaseous fuel shut off valve is closed. The gaseous fuel shut off valve is thereafter opened while the engine is operating in the liquid fuel mode. A liquid fuel rate is determined after the gaseous fuel shut off valve is opened and the liquid fuel rate determined before opening of the gaseous fuel shut off valve is compared with the liquid fuel rate determined after opening of the gaseous fuel shut off valve. A detonation level within the engine cylinder may also be checked to determine if such detonation level exceeds a predetermined level indicative of gaseous fuel leakage. The detonation level check may also be utilized in a spark-ignited engine.

摘要： A method for curing resin in the fabrication of a composite material is described comprising enclosing the composite material within a flexible vacuum enclosure, and substantially simultaneously pressing the material within the enclosure between first and second platens of a press to preselected pressure, evacuating the enclosure, selectively heating one of the platens according to a preselected scheme to preselected cure temperature to cure the resin within the material, and cooling the other platen to maintain a preselected temperature differential between the platens across the thickness of the material, whereby cure of the resin is effected in the material first near the heated platen and progresses through the thickness of the material toward the cooler platen as the material is heated to the cure temperature.

摘要： A method for controlling and adjusting the delivery of liquid pilot fuel to each cylinder of a dual fuel engine during a dual fuel operating mode so as to both minimize the quantity of liquid pilot fuel being delivered to each individual cylinder while, at the same time, ensuring that such minimum quantity of liquid pilot fuel provides complete combustion performance within each such cylinder wherein certain cylinder performance parameters such as exhaust port temperature or cylinder pressure are evaluated on a per cylinder basis in order to determine cylinder performance. The present method establishes certain predetermined incremental changes in the selected cylinder performance parameters, which changes are indicative of poor or deteriorated combustion performance within any particular cylinder, and thereafter varies the amount of liquid pilot fuel delivered to such cylinder based upon an analysis and evaluation of changes occurring in the selected cylinder performance parameters. Although it is preferred that each cylinder be evaluated on an individual basis, it is recognized and anticipated that, in some applications, the present method may be used to control the delivery of liquid pilot fuel to two or more cylinders simultaneously.

摘要： A method for controlling delivery of fuel to each cylinder of an engine by adjusting the appropriate fuel valve duration times to each such cylinder based upon a predetermined detonation level. By using the detonation level measurements from each individual cylinder as a controlling parameter, the delivery of fuel to that particular cylinder can be trimmed to achieve the predetermined detonation level. Balancing the detonation level for each such cylinder to a common detonation level likewise produces a substantially identical air/fuel ratio in each such cylinder. The detonation control loop can be initiated at predetermined intervals so as to continuously maintain a balanced air/fuel ratio to each cylinder in any particular engine.
