Abstract: The present disclosure is directed to a system for mounting an axially staged fuel injector assembly. The system includes an annularly shaped liner that at least partially defines a hot gas path of a combustor. The liner defines an injector opening that extends radially through the liner. A flow sleeve circumferentially surrounds at least a portion of the liner and is radially spaced from the liner to form a cooling flow annulus therebetween. An annular injector boss extends radially from the liner through the flow sleeve. The injector boss includes a first end portion that extends circumferentially about the injector opening and a second end portion that is disposed radially outwardly from an outer surface of the flow sleeve. The injector boss is formed to receive a fuel injector. The present disclosure is also directed to a method for mounting an axially staged fuel injector.

Abstract: A turbine bucket is provided including a bucket airfoil having an airfoil shape, the bucket airfoil having a nominal profile substantially in accordance with Cartesian coordinate values of X, Y and Z set forth in Table 1 wherein the Cartesian coordinate values of X, Y and Z are non-dimensional values from 0% to 100% convertible to dimensional distances in inches by multiplying the Cartesian coordinate values of X, Y and Z by a height of the airfoil in inches, and wherein X and Y are distances in inches which, when connected by smooth continuing arcs, define airfoil profile sections at each distance Z, the airfoil profile sections at Z distances being joined smoothly with one another to form a complete airfoil shape.

Abstract: An apparatus is provided for finding and defining a prescription for prism glasses for Diplopic patients and AMD patients whose Macula and Fovea are damaged enough that the patients have double vision, but, still have relatively good acuity. The apparatus positions lenses in infinitely variable locations horizontally and vertically in front of the patient's eyes until the patient indicates that he/she sees the two images fuse. The H-V coordinates of the location of the Optic center of each lens axis in relation to the patient's visual axis are decentration dimensions indicated for each eye by the H and V dials on the apparatus and are thus the basis for an accurate prescription for prism lenses.

Abstract: An apparatus is provided for finding and defining a prescription for reading glasses for an AMD patient whose Macula and Fovea are damaged enough that the patient has double vision, i.e. the patient sees two images of every object within the field of view of the Macula and Fovea. The apparatus positions reading lenses in various locations in front of the patient's eyes until the patient indicates that he/she now sees one image for each object in the field of view of the Macula and Fovea. The X-Y coordinates of the location of each lens axis in relation to the patient's visual axis are offset dimensions indicated for each eye by the apparatus and is thus the prescription for reading lenses.

Abstract: A typical Christmas tree stand has legs made of stamped metal with thumbscrews threaded through the stamped metal, which provides almost no resistance to lateral movement of the thumbscrews. The rotational action of tightening the thumbscrews actually causes the tree trunk to rotate about its axis thus twisting the thumbscrews laterally and loosening the contact of the thumbscrews with the tree trunk thus allowing the tree to lean or fall over. The present invention is a Christmas tree stand adapter ring, hereinafter referred to as adapter ring, having unthreaded screw holes arranged radially to coincide with thumbscrews in the legs and collar of a typical Christmas tree stand. The adapter ring is positioned inside the collar of the typical Christmas tree stand in an orientation that allows the thumbscrews of the Christmas tree stand to pass through the adapter ring and make contact with the Christmas tree trunk.

Abstract: A multiple contact switch assembly is provided and may be characterized as a four-way rocker switch or as a two axis rocker switch. The switch assembly comprises a rocker body that is supported on a carrier bridge for pivotal movement about one axis. The carrier bridge and rocker body subassembly is attached to a pocket in a bezel for pivotal movement about an axis that is perpendicular to the axis about which the rocker body pivots relative to the carrier bridge. A button face of the rocker body contacts a switch contact dome when the button face is contacted in one of the four quadrants. Contacting the button face between two quadrants is ineffective to make contact with any of the switch contact domes.

Abstract: A standard 2-gang wallbox-mountable light switch assembly comprising two switches for controlling electrical power from two separate circuits, one normal and one emergency power, to two separate lighting loads is disclosed. The assembly comprises two toggle switches, a yoke common to both switches and an axle common to both toggle switches for operating in unison both toggle switches. A single handle is provided that is integral to the axle and extends through the yoke for manual grasping for switching on-off. A partition creates a barrier between the electrical components of the two toggle switches when mounted within a standard 2-gang wallbox. Separation of normal and emergency circuits is a requirement of the National Electric Code (NEC) 700.9 (B).

Abstract: The invention pertains to an extendable directionally adjusted dipole antenna particularly suitable for use with recreational vehicles.
