Abstract: Embodiments of the disclosure include systems and methods for providing a flow of purge air and an adjustable flow of cooling air to a wheel space cavity or a stator cavity. According to one embodiment, there is disclosed a turbine assembly. The turbine assembly may include a rotor assembly, a stator assembly positioned adjacent to the rotor assembly, and a wheel space cavity formed between the rotor assembly and the stator assembly. At least one fixed purge air orifice may be associated with the stator assembly. The fixed purge air orifice may be configured to provide a flow of purge air to the wheel space cavity. Moreover, at least one adjustable cooling air orifice may be associated with the stator assembly. The at least one adjustable cooling air orifice may be configured to provide a flow of cooling air to the wheel space cavity.

Abstract: A method for manufacturing a brush seal is provided including the steps of: (a) providing fiber; (b) providing a packing material; (c) providing a pair of backing plates; (d) arranging the fiber in a particular arrangement; (e) applying the packing material to selective areas of the arranged fiber; (f) cutting the fibers in bristle sections, wherein each of the bristle sections includes a plurality of bristles and one of the selective areas having applied packing material; (g) stacking the bristle sections, such that the selective areas of applied packing material are aligned between the backing plates; and (h) bonding the backing plates, the bristle sections, and the packing material together.

Abstract: An electromagnetic generator without moving parts includes a permanent magnet and a magnetic core including first and second magnetic paths. A first input coil and a first output coil extend around portions of the first magnetic path, while a second input coil and a second output coil extend around portions of the second magnetic path. The input coils are alternatively pulsed to provide induced current pulses in the output coils. Driving electrical current through each of the input coils reduces a level of flux from the permanent magnet within the magnet path around which the input coil extends. In an alternative embodiment of an electromagnetic generator, the magnetic core includes annular spaced-apart plates, with posts and permanent magnets extending in an alternating fashion between the plates. An output coil extends around each of these posts. Input coils extending around portions of the plates are pulsed to cause the induction of current within the output coils.

Abstract: A hand held circular saw rip guide that is attached to a planar base and includes a movable cross member that is disposed about the planar base. An cross member extension serves as a straight-edge to guide the skill saw in operation. An upper surface of the planar base has a graduated series of indicia that represents feet and inches, or any suitable scale, to provide the operator with a tool for measuring the work piece and in combination with the movable cross member allows the operator to measure and cut any desired dimension in the work piece.
