Abstract: A hybrid vane (50) for a gas turbine engine having a ceramic matrix composite (CMC) airfoil member (52) bonded to a substantially solid core member (54). The airfoil member and core member are cooled by a cooling fluid (58) passing through cooling passages (50) formed in the core member. The airfoil member is cooled by conductive heat transfer through the bond ((70) between the core member and the airfoil member and by convective heat transfer at the surface directly exposed to the cooling fluid.  A layer of insulation (72) bonded to the external surface of the airfoil member provides both the desired outer aerodynamic contour and reduces the amount of cooling fluid required to maintain the structural integrity of the airfoil member. Each member of the hybrid vane is formulated to have a coefficient of thermal expansion and elastic modules That will minimize thermal stress during fabrication and during turbine engine operation.

Title: Spreading apparatus for flowable materials
Inventor: PITMAN ROBIN G
IPC: B05C17/10
Filed: 2004-07-02
Abstract: A spreading apparatus is provided for spreading flowable materials such as adhesives and/or sealants on a surface such as a floor and/or a wall. The apparatus has a pad retainer for retaining a removable spreader pad and a reservoir chamber for flowable material pivotally attached to the pad retainer to permit pivoting of the reservoir chamber frontwards and backwards. The reservoir chamber has an adjustable gate through which the flowable material may exit. The gate is proximal the bottom of the reservoir chamber and complementary to the width of the pad retaining means to permit more uniform spreading of the flowable material. A  handle is attached to and extends from the reservoir chamber. The handle may pivot from side to side on the reservoir chamber and may be hollow to house a cable associated with the means for opening the gate. A system is also provided involving the spreading apparatus together with a removable spreader pad and a container containing the flowable material. The container is housed in the reservoir chamber and cooperates with the gate to permit the flowable material to exit the container and the reservoir chamber when the gate is open. The spreader pad comprises an elongated resilient foam member sufficiently thick to fit within and frictionally engage the pad retainer, and sufficiently high to extend below the pad retainer so that the spreader pad rather than the pad retainer contacts the surface when the spreader pad is retained by the pad retainer.
