Abstract: Described is a variable reference blocking apparatus for blocking an optical article (5). The apparatus comprises an adjustable ring unit (11) having a plurality of concentric members (19,19c,19i) positioned about a central axis. Each concentric member (19,19c,19i) generally comprises a lip region (17) on its upper end that is capable of receiving at least a portion of a front face of the optical article (5). The apparatus further comprises a moveable base (13) in which its upper portion is coupled with a removable insert (7). The removable insert (7) is generally positioned to be centered about the front face of the optical article (5).

Abstract: A communication number processing system and methods for processing communication numbers or identifiers of various types to prevent fraud in transactions associated with the communication numbers are disclosed. The communication number processing system, in an example embodiment, verifies a communication number by retrieving characteristics data including network-derived characteristics data and/or other attributes relating to the communication number and processing the characteristics data and/or the attributes based on one or more rules. The communication number processing system further generates a fraud score for the communication number. A client system can then use the fraud score to assess a risk associated with engaging in a transaction with a user associated with the communication number.

Abstract: The cap assembly of a turbine combustor includes a plurality of burner tubes sealed against fuel nozzles extending in the tubes. These piston seals are coated with a high velocity oxygen fuel coating to extend their service life. The outer cap body assembly includes concentric seal rings each with cantilevered convex fingers circumferentially offset from one another to seal between the cap assembly casing and the inner liner. The cap assembly casing is provided with a plurality of holes at predetermined locations about the casing to minimize or eliminate response to combustion dynamics.

Abstract: A fuel nozzle assembly for a gas turbine includes a plurality of circumferentially spaced vanes with holes for flowing fuel from plenums within the vanes through holes in the vane walls for premixing with air. To tune the nozzle assembly, the holes are resized by reforming the existing holes to a predetermined hole size, securing plugs into the holes, and forming holes through at least certain of the plugs to diameters less than the diameter of the existing holes.
