Abstract: A turbine engine having a rotor rotatable about a rotational axis, a stator, a plurality of circumferentially spaced bleed air passages, and an inducer. The plurality of circumferentially spaced bleed air passages being located between an axially adjacent set of vanes of the stator and blades of the rotor. The inducer including a nozzle passage fluidly coupling a nozzle inlet of the inducer to a nozzle outlet of the inducer.

Abstract: A heat exchanger is provided. The heat exchanger includes a first wall manifold. The heat exchanger further includes a second wall manifold spaced apart from the first wall manifold. The heat exchanger further includes a plurality of vanes that extend generally circumferentially between the first wall manifold and the second wall manifold. The heat exchanger further includes a plurality of fluid circuits defined within the heat exchanger. Each fluid circuit in the plurality of fluid circuits includes an inlet channel portion and an outlet channel portion defined within the first wall manifold. A return channel portion defined within the second wall manifold. At least one passage portion of a plurality of passage portions defined within each vane of the plurality of vanes. The at least one passage portion extends between the return channel portion and one of the inlet channel portion and the outlet channel portion.

Abstract: A passive flow modulation device for a machine defining an axial direction and a radial direction, the passive flow modulation device including: a first ring with a first coefficient of thermal expansion; a second ring disposed coaxially with the first ring and positioned at least partially inward of the first ring along the radial direction, spaced from the first ring along the axial direction, or both, the first ring, the second ring, or both defining at least in part one or more passages, the second ring with a second coefficient of thermal expansion that is less than the first coefficient of thermal expansion to passively modulate a size of the one or more passages during operation.

Abstract: A lubricating tube and a lubrication system are configured to lubricate an apparatus having a rolling component. The lubrication system includes a fluid reservoir containing a fluid, a fluid line coupled to the fluid reservoir; and the lubricating tube, which is disposed between the fluid line and the rolling component. The lubricating tube includes a rigid cylindrical body surrounding a cavity and having an outer circumferential surface. An inlet of the lubricating tube is coupled to the fluid line and provides fluid communication between the fluid line and the cavity. A plurality of ports is disposed on the outer circumferential surface and is configured to dispense the fluid to the rolling component. A location of each port of the plurality of ports from the inlet is customizable.

Abstract: A conveyor condition monitor, for use with a conveyor comprising a plurality of trollies running along a conveyor rail and linked to one another by a chain link system, is disclosed. The monitor comprises a conveyor monitoring station and a first deformation sensor. The deformation sensor is in communication with the conveyor monitor, and is adapted to notify the conveyor monitor of the presence of a deformed trolley in the conveyor.

Abstract: A conveyor condition monitor, for use with a conveyor comprising a plurality of trollies (12) running along a conveyor rail (14) and linked to one another by a chain link system, is disclosed. The monitor comprises a conveyor monitoring station (3) and a first deformation sensor (5a, 5b). The deformation sensor (5b) is in communication with the conveyor monitor, and is adapted to notify the conveyor monitor of the presence of a deformed (13b) trolley (12) in the conveyor.

Abstract: A nozzle mount assembly for use in soft excavation. The assembly includes a vacuum tube, nozzle ports, and a wear ring. The vacuum tube defines air flow passages including an open lower end of the vacuum tube and air relief slots located near its lower end. The nozzle ports are defined by a manifold having air troughs located between the nozzle ports. Each nozzle port is configured to receive a high-pressure fluid nozzle. One nozzle port is angled toward the center of the vacuum tube, and two nozzle ports are angled away from the vacuum tube. The nozzle port angled toward the center of the vacuum tube is configured to direct a fluid stream through an air relief slot in the vacuum tube.
