20140060479 | TWO-STAGE PRECOMBUSTION CHAMBER FOR LARGE BORE GAS ENGINES - In certain embodiments, a two-stage precombustion chamber may be used to reduce engine NOx levels, with fueled precombustion chambers, while maintaining comparable engine power output and thermal efficiency. One or more fuel admission points may be located in either the first prechamber stage or the second prechamber stage. A more efficient overall combustion characterized by low levels of NOx formation may be achieved by a two-stage precombustion chamber system while generating very high energy flame jets emerging from the second prechamber stage into the main combustion chamber. A first prechamber stage may be substantially smaller than a second prechamber stage. The volumes and aspect ratios of the two prechamber stages, along with the location of the electrodes within the first stage prechamber, the holes patterns, angles and the separate fueling, may be selected to create a distribution of fuel concentration that is substantially higher in the first stage prechamber compared to the second prechamber stage. | 03-06-2014 |
20140076274 | Time-varying Spark Current Magnitude to Improve Spark Plug Performance and Durability - In certain embodiments, a time-varying spark current ignition system can be applied to improve spark plug ignitability performance and durability as compared to conventional spark ignition systems. Two performance parameters of interest are spark plug life (durability) and spark plug ignitability. In certain embodiments, spark plug life can be extended by applying a spark current amplitude as low as possible without causing quenching of the flame kernel while it is traveling within an electrode gap and/or by applying spark current of a long enough duration to allow the spark/flame kernel to clear a spark plug gap. In certain embodiments, ignitability can be improved by applying a high enough spark current amplitude to sustain the flame kernel once outside the spark plug gap and/or by applying a spark current for long enough to sustain the flame kernel once outside the spark plug gap. | 03-20-2014 |

20110063116 | SENSING NETWORK AND METHOD - A system and method are described for detecting toxic gas releases in an urban environment. The system includes a series of repositionable remote sensor nodes that are located in an environment containing a toxic gas, the sensor nodes including a chemical sensor and/or a meteorological sensor. The sensor nodes gather data relating to the type of gas released and the surrounding atmospheric conditions and relay the information back to a data processing hub where the data is collated and analysed to produce an indication of the likely spread of the gas plume, the likely danger to the surrounding population and an indication of the release point of the gas. | 03-17-2011 |

20100031942 | Silicon-Controlled Rectifier Shut-Off Circuit for Capacitive Discharge Ignition System - A capacitive discharge ignition system for an internal combustion engine and for use with a generator powered current source comprises a storage capacitor, at least one power thyristor for discharging the storage capacitor to transfer energy to at least one coil triggered in synchronism with an internal combustion engine with which the ignition system may be associated. A triggering circuit biases the power thyristor to discharge the storage capacitor. A shut-off circuit comprises a solid state device for switching the output of the generator to ground interrupting the flow of current to the power thyristor. A circuit sensing current flow in the triggering circuit generates a control and gates the solid state device into conduction in response to the control signal. | 02-11-2010 |
20100116028 | Vibration Monitor - A system comprising an amplifier for amplifying signals of frequencies less than one kilohertz generated by a vibration sensor and using the amplified signal to amplitude modulate a carrier signal at a frequency in excess of one kilohertz and applying the amplitude modulated carrier signal to a sensor interface circuit. | 05-13-2010 |
20130054116 | Digital control of gaseous fuel substitution rate for dual-fuel engines - A gaseous fuel control system for a dual-fuel internal combustion engine comprising a plurality of valves for controlling the amount of gaseous fuel supplied to the engine. The valves have adjustable full-open flow rates and rapidly move from full-open to full-closed in response to a digital signal. An electronic system for monitoring at least one engine operating parameter maps the parameter value to control the opening and closing of the valves to establish a desired gaseous fuel flow rate. | 02-28-2013 |
20130076362 | Ion Sensing Method for Capacitive Discharge Ignition - A method of ion sensing in a CD ignition system for an internal combustion engine comprises: a) closing the controllable switch in synchronism with the internal combustion engine for a period of time to transfer energy to the ignition coil primary to cause a spark breakdown across the spark plug; and b) observing the current in the secondary winding circuit indicative of ionization in the vicinity of the spark plug electrodes. | 03-28-2013 |

20090133304 | Durable display apparatus with retention lip - An advertising display apparatus comprising a hollow receiving tube with an essentially closed distal end and an essentially open proximal end enclosed within a base region, means for retaining a preprinted material inserted through said base region, wherein the hollow receiving tube comprises a plurality of faces where at least one face is transparent and through which said preprinted material may be viewed. The hollow receiving tube in conjunction with the essentially closed distal end and the proximal base end act to retain the preprinted material in a protected environment which aids in ensuring a clean, quality representation of the preprinted material for protracted time periods, especially in environments where people may come into repeated contact with the display apparatus and it is desirable to maintain the quality of the preprinted material, such as restaurants, trade shows and retail sales stores. The plurality of faces comprising the hollow receiving tube are preferably of a convex shape for enhancing retention of the preprinted material and ensuring positive engagement of the preprinted material up to and against the respective face. Included within the base region is a printed material retention lip which extends into and partially occludes the essentially open proximal end of the hollow receiving tube. The base region is designed to allow the display apparatus to remain stable when set upon a flat horizontal surface and may optionally include additional fitments to allow for attachment of the display apparatus to surfaces not of a flat horizontal orientation. The base region may further include means for producing light or sound so as to enhance the attractive attention value of the display apparatus. | 05-28-2009 |
