  • Patent number: 8487496
    Abstract: A retention system in which rotor pole pieces are retained within complementarily shaped channels in a rotor hub, permanent magnets are secured between the pole pieces and within clamp members, and wedge-shaped pieces are used to apply positive locking forces along the axial length of each clamp member and of adjacent pole pieces. A curable resin preferably in disposed within gaps between the permanent magnets and the clamp members.
    Type: Grant

  • Patent number: 7385973
    Abstract: A method and apparatus for a first network device to identify the VLAN for which the first network device is a member. In response to the broadcasting of a discovery request message by the first network device, a second network device transmits a first data message including VLAN information relating to the VLANs configured on the network. From the VLAN information, the first network device determines the VLAN ID of the VLAN in which the first network device is a member.

  • Patent number: 6931029
    Abstract: A system for re-establishing synchrony with data that was synchronous data in a source device but for which synchrony is lost when the data is transmitted over an asynchronous and unreliable medium to a destination device. The system includes buffering of the data received in the destination device from the asynchronous network, readout of the buffers according to a clock, and adjusting the rate of the clock in the destination device according to the rate of transmitting the data from the source device. The clock rate is thus adjusted to re-establish synchrony, and the clock may be used to control synchronous handling of the received data within the destination device.

  • Publication number: 20050031444
    Abstract: A cooling circuit is provided within a turbine nozzle to help increase turbine efficiency. The turbine nozzle includes first, second and third cavities, an outer band, and an inner band. The cooling circuit contains an inlet receiving cooling medium flow, and a first duct insert disposed in the second cavity. The first duct insert receives the cooling medium flow via the inlet and duct flows the cooling medium flow to a bottom of the second cavity. An impingement insert is disposed in the first cavity that receives the cooling medium flow from the first duct insert. A first impingement plate is disposed within the outer band defining an outer band cooling path within the outer band. The outer band cooling path receives the cooling medium flow from the first cavity. A second cavity cooling path is defined between the first duct insert and a second cavity wall, where the second cavity cooling path receives the cooling medium flow from the outer band cooling path.
