Abstract: A gas turbine engine having a waste heat recovery system is provided. The gas turbine engine includes a compressor section, a combustion section, a turbine section, and an exhaust section in serial flow order and together defining a core air flowpath, the exhaust section including a primary exhaust flowpath and a waste heat recovery flowpath parallel to the primary exhaust flowpath; and the waste heat recovery system includes a heat source exchanger positioned in thermal communication with a first portion of the waste heat recovery flowpath.

Abstract: A stump grinder for a powered cutting wheel attached to a boom is disclosed, wherein the improvement relates to a cutting wheel confinement system which includes a cutting wheel further comprising a coaxially disposed spindle extending from an unsupported side, and a boom which further comprises an opening which is centrally disposed with the spindle and sized so as to allow the spindle to freely rotate therein without contact when the cutting wheel is not rotating, and to allow for a predetermined amount of eccentric motion of the spindle before the spindle makes contact with the first opening, and which prevents more than a predetermined amount of eccentric motion of the spindle by confining the eccentric motion of the spindle via contact with the first opening.

Abstract: A sheet of material having a first layer of a first density is patterned to include a main body having a plurality of sides and a side member pivotably attached to the main body adjacent at least one side thereof. At least one relief is formed in the main body for decoupling a portion of the main body from the respective side member. The reliefs permit the side member to move relative to the decoupled portion of the main body in a direction generally perpendicular to the respective side of the main body. The sheet of material may further include a second layer of a second density, different than the first density. The second layer is patterned to form a hinge between the main body and each respective side member to enable each side member to be pivotable relative to the main body.
