  • Patent number: 10465128
    Abstract: A thermal cracking apparatus and method includes a body having an inner volume with a longitudinal axis, where a reaction zone surrounds the longitudinal axis. A feedstock process gas is flowed into the inner volume and longitudinally through the reaction zone during thermal cracking operations. A power control system controls electrical power to an elongated heating element, which is disposed within the inner volume. During thermal cracking operations, the elongated heating element is heated to a molecular cracking temperature to generate the reaction zone, the feedstock process gas is heated from the elongated heating element, the power control system uses a feedback parameter for adjusting the electrical power to maintain the molecular cracking temperature at a substantially constant value, and the heat thermally cracks molecules of the feedstock process gas that are within the reaction zone into constituent components of the molecules.

  • Patent number: 10288294
    Abstract: A combustion staging system has a splitting unit receiving and splitting metered fuel flow into out-going pilot and mains flows; pilot and mains fuel manifolds receiving the pilot and mains flows; and parallel mains flow scheduling valves distributing the mains flow. The mains flow scheduling valves pass the pilot fuel flow to injector pilot discharge orifices. Each mains flow scheduling valve has a chamber containing a piston, the chamber to a piston pilot side communicating with the pilot fuel manifold and the chamber to a mains side of the piston communicating with the mains fuel manifold. The piston is biased towards a closed pilot-only position preventing flow out of the chamber mains side to the injector mains discharge orifice. The piston is movable under increased pressure in the mains fuel manifold to an open pilot-and-mains position allowing flow out of the chamber mains side to the injector mains discharge orifice.

  • Publication number: 20180372323
    Abstract: A combustion staging system is provided for fuel injectors of a multi-stage combustor of a gas turbine engine. The system has a splitting unit which receives a metered total fuel flow and controllably splits the metered total fuel flow into out-going pilot and mains fuel flows to perform pilot-only and pilot-and-mains staging control of the combustor. The system further has pilot and mains fuel manifolds which respectively receive the pilot and mains fuel flows. The system further has a plurality of mains flow scheduling valves which distribute the mains fuel flow from the mains fuel manifold to mains discharge orifices of respective injectors of the combustor. The system further has servo line which extends to the mains flow scheduling valves, the servo line being controllably fillable with pressurised fuel to change the pressure in the servo line relative to the pressure in the mains fuel manifold.

  • Publication number: 20180312907
    Abstract: The present invention relates to methods of detecting and treating a bacterial infection, such as bacterial meningitis, and addresses the problem of misdiagnosis of bacterial infections. The medical use of antibacterial agents in the treatment of a bacterial infection in a subject identified by the methods of the invention is also described. The methods of the invention comprise assaying a sample from the subject to obtain data of the relative abundance of target molecules indicative of the expression of at least one gene pair, determining the presence or absence of a bacterial infection in the subject in dependence on the data, and optionally treating the subject with an antibacterial agent if required.

  • Publication number: 20180163636
    Abstract: The fuel supply system includes mains pressurising and metering arrangement including a positive displacement ecology pump and an ecology valve piston chamber and a piston slidably movable in the chamber between de-prime and re-prime positions, the chamber forming a fuel sink to one side of the piston which increases in volume when the piston moves to de-prime position and reduces in volume when the piston moves to re-prime position. The ecology valve is fluidly connected to the ecology pump for pilot-only operation reverse direction operation of the ecology pump causes the piston to move to de-prime position removing mains fuel from injectors through a mains fuel distribution pipework and into the fuel sink, and for pilot and mains operation the forward direction operation of the ecology pump causes the piston to move to re-prime position refilling injectors with mains fuel from the fuel sink.

  • Publication number: 20180163637
    Abstract: A fuel supply system includes a metering and splitting arrangement receiving a fuel flow and controllably meters and splits the received fuel flow into metered pilot and mains flows for injecting at injector pilot and mains fuel discharge orifices to perform combustor staging control. The system includes an ecology valve having a piston chamber and a piston slidably movable in the chamber between de-prime and re-prime positions, the chamber forming a fuel sink to one side of the piston which increases in volume when the piston moves to its de-prime position and reduces in volume when the piston moves to its re-prime position. The system includes an actuator for actuating the piston. The valve is fluidly connected to a mains fuel distribution for operating the piston to its de-prime position to remove the mains fuel from the injectors through the mains fuel distribution pipework and into the fuel sink.

  • Patent number: 9739208
    Abstract: An engine fuel control system is provided, including a supply line for the supply of fuel to a fuel metering valve which controls the flow of fuel to burners of an engine. Fuel is delivered at a first high pressure to the supply line by a pump arrangement. The engine fuel control system includes a restrictor located in the supply line for passage of the fuel delivered by the pump arrangement therethrough. The restrictor is configured such that fuel exiting the restrictor for onward supply to the fuel metering valve is at a second high pressure which is lower than the first high pressure. The engine fuel control system includes pressure limiting valves which actuate when the pressure difference between the first high and low pressure reaches a predetermined level to open a flow path for fuel on the supply line to by-pass the restrictor, thereby limiting the pressure difference.

  • Patent number: 9617923
    Abstract: An engine fuel control system includes a fuel metering valve that controls the flow of fuel between supply and delivery lines which delivers fuel to engine burners. The fuel control system includes a fixed displacement main pump which receives fuel from a low pressure source and delivers the fuel at a first high pressure to the supply line, an augmenter pump which receives fuel from the low pressure source and delivers the fuel at a second high pressure to one or more fuel-pressure operated auxiliary engine devices, and a start valve which is actuated at low engine speeds to open a flow path which diverts fuel delivered by the augmenter pump away from the auxiliary engine devices to the supply line to augment the fuel delivered thereto by the main pump, the start valve being actuated at higher engine speeds to shut the flow path.
