Abstract: A granular litter cleaning apparatus comprises a separation system having a separation tank adapted to receive a mixture of granules and plastic litter, and water therein, the separation tank having a top opening, and a closeable bottom outlet, and at least one water inlet for feeding water to the separation tank. A collect subsystem is for conveying a mixture of granules and plastic litter to the separation tank. A pump system is in fluid communication with the water inlet. The pump system is operated to raise a level of water in the separation tank to skim water with plastic litter out through the top opening of the separation tank. The closeable bottom outlet is openable to empty the separation tank from granules decanted in a bottom of the separation tank. A process for separating plastic litter from granules is also provided.

Abstract: A stator of a turbine section, has: vanes distributed around a central axis, a vane of the vanes extending along a spanwise axis and defining an internal passage; an insert received within the internal passage, the insert defining a cavity for receiving cooling air and defining impingement cooling apertures facing an inner face of the vane; a splitter plate secured within the cavity and being transverse to the spanwise axis, the splitter plate having a base secured to the insert and a tip protruding from the base; and a flow passage defined between the tip and the insert, the flow passage fluidly connecting a first section of the cavity to a second section of the cavity, the tip of the splitter plate secured to the insert at at least one location along a perimeter of the tip.

Abstract: The gas turbine engine includes a casing assembly located proximate a turbine section of the gas turbine engine, and a tangential on-board injector (TOBI) having a body defining a plurality of air passages extending in a radial direction, the plurality of air passages circumferentially distributed and directing cooling air toward a turbine rotor of the turbine section of the gas turbine engine. An interference fit is provided between a face of the body and a face of a member of the casing assembly, the interference fit defining a fastener-free engagement between the bearing housing and the TOBI to prevent relative movement between the member of the casing and the TOBI.
