  • Patent number: 9038706
    Abstract: A method of forming a cast product (30) by providing a core (52) having a plurality of sections (54) and one or more gaps (55) there-between. The core further includes an insert member (60) spanning the gap (55) between adjacent sections (54). The core (52) is located within a mold (68) and a liquid phase material is introduced into gap (55) between the core sections. The liquid phase material is solidified in the gap so as to form a cast feature of a resulting solid product and the core sections (54) are removed from the solid product (30) such that the insert member (60) remains securely held within the feature (74).

  • Patent number: 7744344
    Abstract: Vanes are generally hollow with a passage through which service pipes extend. These service pipes must be connected such that they can allow for thermal expansion and contraction but also anti rotation features are needed in order to prevent damage when a supply coupling is connected through a pipe end. This anti-rotation feature is generally provided between a top hat and a pipe end through flanges. In order to allow reduced spacing between the top of the vane and a casing the flanges are arranged to allow at least recessing of a first flange into a passage opening profile whereby those flanges inter-engage with second flanges at a surface interface to prevent rotation.
