20090155598 | Coatings and Coating Systems for Metal Substrates - Disclosed are methods of treating a metal to improve the metal's corrosion resistance. In one such method, the method is carried out by applying, to the surface of the metal, a coating which includes magnesium powder and a UV-curable or other radiation-curable binder. In another such method, the method is carried out by applying, to the surface of the metal, a coating which includes magnesium powder and an inorganic binder. In another such method, a coating that includes a magnesium alloy powder and a binder is applied to the surface of the metal. The magnesium alloy powder is selected such that it has a corrosion potential that is from about 0.01 volt to about 1.5 volt more negative than the metal's corrosion potential. Also disclosed are methods of treating a ferrous metals and magnesium alloys to improve the corrosion resistance of these materials. | 06-18-2009 |
20130302628 | PROTECTIVE COATING - A protective coating including a crosslinked polyester that is removable with a basic composition, as well as coated articles, methods of preparing a protective coating, and methods of using a protective coating. | 11-14-2013 |
20140191163 | METHOD OF APPLYING A MAGNESIUM-CONTAINING POWDER TO THE SURFACE OF AN ALUMINUM OR ALUMINUM ALLOY SUBSTRATE - Disclosed are methods of treating a metal to improve the metal's corrosion resistance. The method includes applying, to the surface of the metal, a coating which comprises magnesium powder and a binder. The present invention also relates to a coating composition that includes magnesium powder and a silane modified epoxy isocyanate hybrid polymer or prepolymer. The inventors have found that corrosion resistance (as determined by Prohesion™ exposure in accordance with ASTM D5894-96, which is hereby incorporated by reference) in excess of 3,000 hours on 2024 T-3 aluminum alloy can be achieved with the methods and coating compositions of the present invention. | 07-10-2014 |

20120185684 | BOOTING A MOBILE ELECTRONIC DEVICE WITH A LOW BATTERY BASED ON A DYNAMIC BOOT THRESHOLD - A method, an apparatus, and a computer program product for booting the apparatus with a low-energy battery are provided. In a first configuration, the apparatus monitors a level of the battery while the battery is charging. The apparatus attempts a boot of the apparatus when the level is greater than or equal to a dynamic boot threshold. The apparatus increases the dynamic boot threshold when the boot is unsuccessful and repeating the monitoring and the attempting based on the increased dynamic boot threshold. In a second configuration, the apparatus detects a connection to an external power source. The apparatus attempts a boot using an FLCB protocol that is based upon power drawn directly from the external power source upon detecting the connection to the external power source. The apparatus attempts the boot as part of an ATC protocol when the boot using the FLCB protocol is unsuccessful. | 07-19-2012 |

20120160221 | Method And Apparatus Of Fuelling An Internal Combustion Engine With Hydrogen And Methane - A gaseous-fuelled internal combustion engine and a method of engine operation improve combustion stability and reducing emissions of NOx, PM, and unburned hydrocarbons. The method comprises fuelling an internal combustion engine with hydrogen and natural gas, which can be directly injected into the combustion chamber together or introduced separately. Of the total gaseous fuel delivered to the engine, at least 5% by volume at standard temperature and pressure is hydrogen. For at least one engine operating condition, the ratio of fuel rail pressure to peak in-cylinder pressure is at least 1.5:1. A fuel injection valve introduces the gaseous fuel mixture directly into the combustion chamber. Two separate fuel injection valves could also introduce the methane and hydrogen separately. An electronic controller controls timing for operating the fuel injection valve(s). The engine has a preferred compression ratio of at least 14:1. | 06-28-2012 |
20130179050 | Gaseous-Fuelled Stoichiometric Compression Ignition Internal Combustion Engine - In a gaseous-fuelled stoichiometric compression ignition internal combustion engine, a pilot fuel is injected directly into the combustion chamber to help initiate a multi-point ignition. The engine provides performance improvements approaching those of high pressure direct injection engines but with less complexity because the gaseous fuel is introduced into the intake air subsystem at relatively low pressure and as a result of the stoichiometric combustion, the low oxygen content in the combustion products exiting the combustion chamber allows the use of a three-way catalyst instead of other after treatment arrangements normally associated with conventional compression ignition engines that require the addition of a reductant. | 07-11-2013 |
20150020769 | Apparatus And Method For Igniting A Gaseous Fuel In A Direct Injection Internal Combustion Engine - An apparatus and method for igniting a gaseous fuel directly introduced into a combustion chamber of an internal combustion engine comprises steps of heating a space near a fuel injector nozzle; introducing a pilot amount of the gaseous fuel in the combustion chamber during a first stage injection event; controlling residency of the pilot amount in the space such that a temperature of the pilot amount increases to an auto-ignition temperature of the gaseous fuel whereby ignition occurs; introducing a main amount of the gaseous fuel during a second stage injection event after the first stage injection event; and using heat from combustion of the pilot amount to ignite the main amount. | 01-22-2015 |
