Patent number: 8745281Abstract: A device includes an interface configured to receive an indication of a second device on a network, and a processor configured to determine if the indication is one of an expected set of indications and generate a permanent node address for assignment to the second device if the indication is one of an expected set of indications. The permanent node address places the second device into an active mode as a permanent node addressed device. The processor is further configured to receive at least one device parameter from the permanent node addressed device, determine if the at least one device parameter matches an expected device parameter for the permanent node addressed device, and generate a second permanent node address for assignment to the device if the at least one device parameter matches the expected device parameter for the permanent node addressed device.Type: GrantFiled: April 23, 2012Date of Patent: June 3, 2014Assignee: General Electric CompanyInventors: John Alexander Petzen, Andre Steven DeMaurice, Dana Robert Kreft, William Kennedy Galt, William Robert Pettigrew

Patent number: 8352641Abstract: Systems and methods for identifying one or more Fieldbus devices in a control system are described. One or more messages from respective linking devices and including information associated with a plurality of segments for the linking devices may be received and analyzed to identify one or more segments to which at least one Fieldbus device is connected. A respective query message requesting information associated with connected Fieldbus devices may then be generated and communicated to each identified segment. One or more responses to the query messages may be received and utilized to prepare a listing of the Fieldbus devices that are included in or connected in the control system.Type: GrantFiled: April 21, 2010Date of Patent: January 8, 2013Assignee: General Electric CompanyInventors: William Robert Pettigrew, Dana Robert Kreft

Patent number: 4132503Abstract: A variable-pitch propeller has a hollow hub rotatable about a hub axis and carrying a plurality of angularly equispaced vanes each rotatable on the hub about a respective vane axis extending radially of the hub axis. Each of the vanes has an eccentric pivot pin parallel to its respective vane axis and connected via a bearing to one end of an arm formed on an adjustment member displaceable in the hub along the hub axis and rotatable in the hub about the hub axis. The bearing allows for rotation of the pivot pin relative to the arm in which it is received and for displacement of the pivot pin along the pivot axis relative to the arm receiving it. Thus axial displacement of the adjustment member will force the pivot pins to orbit limitedly about the respective vane axes with concomitant sliding of the bearing along the pin and simultaneous rotation of the adjustment member in the hub.Type: GrantFiled: March 25, 1977Date of Patent: January 2, 1979Assignee: Schaffran Propeller Lehne & Co.Inventors: Robert Kreft, Udo Torper
