摘要： A vent apparatus is used to install a tankless water heater or similar equipment inside an attic without going onto the roof. The vent apparatus may include a main housing and an umbrella assembly movably disposed therein. The main housing (e.g., PVC pipe) is installed through the roof. The umbrella assembly may have a central rod with a flexible umbrella cover on top. The umbrella assembly is pushed up through the main housing until the umbrella cover exits the top of the main housing to cover it and prevent rain from entering the main housing. The bottom of the main housing is then connected to the tankless water heater. Additional embodiments are disclosed for tankless water heaters and other equipment with an air intake port and a gas exhaust port.

摘要： The lighter is an ignition device. The lighter includes a housing structure, a fuel system, and an ignition circuit. The housing contains the fuel system and the ignition circuit. The fuel system provides the ignition circuit with a supply of a hydrocarbon based fuel. The ignition system provides the fuel with a source of plasma that is used to initiate a combustion reaction that converts the fuel into a flame. The ignition system continuously provides the plasma to the fuel to ensure that the flame is continuously sustained.

摘要： An aircraft has first and second fuel sources containing fuels with different characteristics, and one or more gas turbine engines powered by the fuels and each having a staged combustion system having pilot and main fuel injectors and being operable in pilot-only and pilot-and-main ranges of operation. The gas turbine engines each have a fuel delivery regulator arranged to control fuel delivery to the pilot and main fuel injectors. The method includes: obtaining a proposed mission description; obtaining nvPM impact parameters for the gas turbine engines, the impact parameters being associated with each operating condition of the proposed mission; calculating an optimised set of one or more fuel characteristics for each flight condition of the proposed flight defined in the flight description based on the nvPM impact parameters; and determining a fuel allocation based on the optimised set of one or more fuel characteristics.

摘要： An assembly is provided for a turbine engine. This assembly includes a combustor, a fuel-air mixer and a mixer guide. The combustor includes a bulkhead. The fuel-air mixer includes an inner passage, a sidewall and a fuel circuit. The inner passage extends axially along an axis within the fuel-air mixer. The sidewall extends circumferentially around and axially along the inner passage. The fuel circuit includes a first fuel passage and a first fuel nozzle outlet fluidly coupled with the first fuel passage. The first fuel passage is embedded within the sidewall and extends along the inner passage. The fuel circuit is configured to direct fuel into the inner passage through the first fuel nozzle outlet. The mixer guide couples the fuel-air mixer to the bulkhead. The mixer guide is configured to slide axially along the fuel-air mixer.
